Apply the Preservation Process Successfully
Last updated: 05-23-2012
Work on historic buildings, landscapes, archaeological sites, or other cultural resources, requires knowledge of a unique process of compliance and review. This process differs from work on existing buildings or on new construction and should be considered in concert with other project goals requiring close collaboration between preservationists and design disciplines. To ensure a balanced, economically viable, and preservation-sensitive project, the outline below should be followed.

Determining What Makes a Building Historic
Properties may be designated as historic at the federal, state, and/or local government levels. Designation recognizes a property's historic, architectural, and community value, and from a sustainability perspective, is an indication that a building is worthy of preservation. All designating agencies use qualifications that emphasize age (usually 50 years old and older), historic significance, architectural and engineering merit, and integrity of design, character, workmanship and materials. Integrity means how well a building or property has retained the important aspects of its historic construction, appearance and association. Buildings, structures, objects, and sites may be designated individually, or as part of a historic district or larger cultural landscape. The National Register of Historic Places is administered by the National Park Service in partnership with State Historic Preservation Officers (SHPOs), Tribal Historic Preservation Officers (THPOS) and Federal Preservation Officers (FPOs). The National Register eligibility criteria, which are often adopted or adapted for use in state and local designation processes, are:
- Resources that are associated with the events that have made a significant contribution to the broad patterns of historic; or
- Resources that are associated with the lives of persons significant in our past; or
- Resources that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or
- Resources that have yielded or may be likely to yield information important in prehistoric or history.

Written and photographic documentation of a property, including a narrative description and a statement of significance, is required for nomination. This documentation, presented in the National Register of Historic Places Registration Form (NPS Form 10-900) or a state or local inventory form, is a key source of information to use in planning for treatment of a building. An on-line index of National Register properties is available at http://www.nps.gov/nr/.
Some income producing properties listed on the National Register, or eligible for listing on the National Register, may qualify for a federal historic preservation tax credit. States may also offer state tax credits to eligible properties.
National Register designation offers some protection when federal actions may impact a property. Federal financial assistance, permit, or license trigger a consultative review process known as Section 106 review which aims to avoid, minimize, or mitigate adverse effects on historic properties. The protections apply when properties are eligible, even if they are not officially listed on the National Register. Private actions are not regulated on National Register listed properties, although local zoning may impose local review requirements if changes are proposed for a historic building. Some states also have state laws that protect historic properties.
State Historic Preservation Offices (SHPOs) are sources of information on designated historic buildings, tax credits, and relevant laws and regulations. See http://www.ncshpo.org/ for a list of SHPO contacts.
Conduct Investigation and Research
Completing a state and/or national historic register nomination requires general knowledge of the resource type being considered (building, landscape, archaeological site), which necessitates investigation and historical research requiring qualified preservation professionals. Procuring qualified preservation professionals can make the process more efficient. (Refer to section on Form a Qualified and Experienced Project Team in Section B below.) There may also be regulations, guidelines, and applicable codes that must be followed. Preparing a nomination should be done in consultation with the consulting agencies (State Historic Preservation Office, the Federal Preservation Office, and the Tribal Historic Preservation Office) to make certain all requirements are met. Nominations for federal properties in certain historic districts must also be reviewed by the local historic preservation commission.
Understand the History of a Property
For the long-term preservation of a historic property, it is very important to understand its history before any construction begins. Consider the following:
- When was it built?
- With what materials and methods was it built?
- Who was the architect or designer?
- What are its architectural characteristics or features?
- Are these features unique in some way?
- What is their condition and will they be lost if not repaired in a timely manner?
- Are original drawings or other planning documents for a building still available?
- Has the building changed over time? If so, how?

Archival research to verify the original appearance of the building and site is helpful in establishing preservation priorities and in preparing treatment alternatives.
An excellent planning tool for successfully completing a project for any historic resource is to develop a Preservation Management Plan. This document records a resource's history, why it is significant, what are the most important features to preserve if work is completed. The plan delineates which areas require special protection or which areas first merit rehabilitation. The preservation management plan guides future maintenance, repairs, and alterations. Some also provide detailed guidance for rehabilitation or adaptive use.
The following are sources to aid in archival research concerning the property:
- American Association of State & Local History
- American Historical Association
- Historic American Buildings Survey (HABS)—for architectural documentation
- Historic American Engineering Record (HAER)—for sites and structures documentation
- Library of Congress
- National Archives
- National Register of Historic Places—National Register Research
- State Historic Preservation Offices
- State Nonprofit Preservation Alliances
- State archives, newspapers, historical societies, libraries, and genealogical societies
- Local preservation commissions, archives, newspapers, historical societies, libraries
Determine the Regulation, Guidelines, and Standards When an Activity is Planned That Affects the Proposed Work
When a treatment is proposed for a historic property, compliance involving a variety of public agencies may be required. Compliance with federal preservation laws is mandatory if the property is using federal funds, leases, grants, permits, or licenses (even if the historic resource is privately owned), is on federal land, or is under the jurisdiction of the federal government. To save time and money, determine ahead of time who must review the preservation project and learn what is required for approval (at all governmental levels).
Section 106, 36 CFR Part 800, Protection of Historic Properties: Section 106 regulations require that the head of any federal agency "prior to the approval of the expenditure of any federal funds on the [construction] undertaking take into account the effect of the undertaking on any [historic] district, site, building, structure, or object". Or, more simply, if federal funds are used to do work on an individual property, then studies must be conducted to determine the potential effect of the work on the property. If any historic or cultural resource (building, land, structure, object, or feature) will be adversely affected by the work, then mitigation and/or remedial plans must be made, as well as a plan to suitably document any resource to be lost. The Advisory Council on Historic Preservation establishes policy on this process.
Section 110: Section 110 regulations require that each federal agency establish and maintain a "preservation program for the identification, evaluation, and nomination to the National Register of Historic Places, and protection of historic properties" for all properties owned by or under the jurisdiction of the agency, thus providing responsible management of current and future historic properties under their care.
For more information on compliance with Section 106 and Section 110, refer to the following:
- The Advisory Council on Historic Preservation
- Federal Preservation Officers (FPO)—For projects affiliated with an agency of the federal government
- State Historic Preservation Officers (SHPO)
- Tribal Historic Preservation Officers (THPO)—For projects affiliated with a property located on or owned by a Sovereign Tribe recognized by the United States federal government
Sometimes there are historic easements, covenants, mechanisms of title transfer, or other legal agreements placed on historic properties that can restrict work undertaken.

- Façade Easements
- National Trust Easements Resources
- Easements to Protect Historic Properties: A Useful Historic Preservation Tool with Potential Tax Benefits (PDF 314 KB, 7 pgs)
There are also binding commitments that federal agencies make with specific regulators that must be taken into consideration. These arrangements are established to protect significant historic, archeological, or cultural resources, and to ensure that the property's intrinsic values will be preserved for future generations through subsequent ownership.
For information on compliance to local regulations, refer to the following:
- Certified Local Governments
- Historic Preservation Review Boards (contact local historic or preservation society, permitting board, or county clerk)
- National Environmental Protection Act (NEPA)
Codes Compliance—Building Codes and Historic Buildings
Until recently, building codes were generally written exclusively for new construction with few provisions made for historic buildings and their unique requirements. New codes are now being developed for older structures on local, state, and national levels. These include those listed in the Relevant Codes & Standards section below.
Additionally, significant older buildings often qualify for zone or code variances if provisions are not explicitly made for historic buildings in the state or local code. Federal Agencies must adhere to other mandates, such as those listed in the WBDG Mandates/Reference section. Federal employees embarking upon a project involving a historic building in addition to checking with the agency's Federal Preservation Officer (FPO), should check with their environmental compliance office, preservation office, and/or facilities division for immediate requirements that must be adhered to.
Identify the Character-Defining Features of the Historic Property
Character-defining elements of the U.S. Capitol include: symmetrical massing, the prominent dome, and extensive grounds

Two terms commonly used in the Standards—and in historic preservation in general—are important for this discussion: the 'historic character' and the 'integrity' of a property. 'Historic character' is, in essence, the things that make a building special—its 'visually distinctive features, materials, and spaces,' for example, or the architectural styling of a structure or its unique methods of construction or craftsmanship. 'Integrity' refers to whether or not a building retains these important 'character-defining' features and has not been inappropriately changed over time.
The terms "character-defining" or "architectural character" refer to all those distinctive elements and physical features that comprise the appearance of every historic building. Character-defining aspects of a historic building include its massing, materials, features, craftsmanship, decorative details, interior spaces and features, as well its site and environment.
Consider the following in identifying the character defining features of the historic property:
- Setting, landscape features, district, or neighborhood
- Spatial definition and volume
- Roof profile
- Window and door pattern
- Elements and assemblies
- Envelope materials
- Interior materials
- Color and texture
- Decoration (ornamentation and artwork)
- Fixtures and furnishings

Following are recommended sources to aid in the investigation and to help identify a building's most salient features:
- National Park Service: Preservation Brief 17—Architectural Character: Identifying the Visual Aspects of Historic Buildings as an Aid to Preserving Their Character
- National Park Service: The Walk Through—Identifying the Visual Character of Historic Buildings
- National Park Service: The Good Guides—A group of websites developed by the National Park Service to help people new to the preservation field understand how to care for historic buildings.
- National Park Service: The Illustrated Guidelines for Rehabilitating Historic Buildings—the online version of the book. The print version is available through the Government Printing Office.
- National Park Service: A Checklist for Rehabilitating Historic Buildings
Fit the Program to the Historic Building

The goal of preservation is to protect the historic integrity of an individual building and its surroundings. Once the important features of a property are identified, their protection is a priority. The design process should respect and respond to the historic features.
Consider the following:
- Can the new use be adapted to preserve the integrity and character of the building?
- Can the design include provisions for protecting the property from the wear and tear associated with active use?
- What should tenant do to ensure long-term protection of the resource?
- Does it involve removing too much of the original architectural materials, changing the plan, or adding an addition that will adversely affect the historic construction?
- Are there alternative approaches that will save more historic fabric?
- Is it feasible to adapt this property to meet the programmatic needs?
- Is it possible to satisfy federal, state, and local regulations and compliance that deal with historic preservation?

B. Planning Stage
Form a Qualified and Experienced Project Team
A historic property's architectural integrity and successful long-term preservation rest on decisions made throughout the entire design and construction process. Therefore, assembling an experienced, competent project team is extremely important. The selected preservation professionals should have experience working on similar historic preservation projects (e.g., the same building type or property), and understanding their unique requirements.
Historic building surveys, planning documents, and technical studies concerning repair and alteration of historic material and spaces should be prepared only by firms and individuals meeting, at a minimum, Department of Interior qualification standards for the applicable preservation professions. This should also be done in accordance with the Secretary's Standards for the Treatment of Historic Properties. These individuals include but are not limited to architectural conservators, architectural historians, preservation architects, preservation engineers, and other allied preservation professionals. If possible, it is recommended to include one or more people with knowledge, skills, and experience in the preservation trades and crafts on the team for historic preservation projects. Preservation trades people can be very helpful in the planning and design process in the survey of needs, temporary removal of building fabric for investigation of hidden features and problems, development of scope, suggesting and reviewing treatment and repair options, estimating quantities, and review of construction details and specifications. Having an interactive relationship between designers and preservation trades people in the design process can often reduce project unknowns, reduce likelihood of change orders, and help in quality control. Preservation trades people can also produce mock ups of preservation treatments that can be used in the bid process as the standard of technique, results and/or quality expected in the project construction phase. See Resources section below for referrals to preservation trades and crafts people, or check with SHPO offices or local preservation organizations for referrals in your area.
Some agencies have developed criteria and procedures for evaluating the competency of preservation professionals and construction contractors.
There are many sources for finding good expertise in historic preservation, including:
- Federal Preservation Officer (FPO)—For Federal Agencies. Some agencies also have preservation professionals on staff or on contract.
- GSA Preservation Professionals
- Construction Contractors
- State Historic Preservation Officer (SHPO)—SHPOs often have lists of individuals with this type of experience.
- How to Find Preservation Professionals
Develop Individual Preservation Management Plans
Continuing the preservation process with sound preservation planning is the next course of action. Prior to construction, it is essential to create a planning document outlining the significance of a historic building, documenting the qualities and elements that contribute to its historic character, establishing preservation priorities, and addressing how the building is to be treated. This type of plan is often called a "preservation management plan" or "Historic Structures Report." In government agencies, this type of document may also be referred to as an Integrated Cultural Resource Management Plan (ICRMP) and Building Preservation Plan (BPP). In addition, a "Cultural Landscape Report or Inventory" may also need to be prepared.
For additional information on preservation management plans, click here.
Federal regulation requires development of individual preservation management plans if the property is federally owned or uses federal funds. The plan can take many forms, but MUST include the following types of information:
- Key Historical Information (when, who, what, where)
- Archival Research (including historic drawings and photographs if available)
- Site Survey Information
- Statement of Significance
- Identification of Character Defining Features
- Documentation of Existing Conditions
- Captioned and Mapped Photos of Existing Conditions (interior and exterior)
- Description of Existing Physical Conditions (on the interior and exterior)
- Materials Analyses
- Overall Conditions Assessment
- Structural Analysis
- Fabric Analysis, Including Paint Analysis; Masonry
- Recommendations for Appropriate Treatments
- Future Compliance Requirements (where applicable as required by law)
The following types of information may be included in a preservation management plan or Historic Structures Report:
- Disaster Mitigation/Management Plan
- Preservation Maintenance Plan
- Establishment of Preservation Zones
- Design Concept (for preservation, rehabilitation, and restoration of building)
- Feasibility Study for Reuse of Building
- Narrative History of Use (construction campaigns, alterations, and additions)
- Description as Built
- Project Scope of Work and Specifications
- Structural Analysis
- Life-Cycle Analysis
Plan Suitable Spaces for Program Needs

Preservation management plans identify character-defining qualities and establish preservation priorities for matching program functions to specific buildings or spaces. The goal is to make the best possible use of existing historic features, minimizing the need for interventions that might compromise the historic character of the building or site. Comprehensive planning is encouraged so that all changes, large or small, are part of a well-integrated building plan, as opposed to piecemeal alterations undertaken without regard to long-term effects.
Preservation zoning establishes a hierarchy based on architectural merit, historic significance, and historic integrity, or the extent to which original materials and design remain intact. These zone categories are then correlated to appropriate levels of treatment, in accordance with the Secretary of the Interior's Standards. The proportion of zones dictating a stricter vs. more lenient design approach is unique to each building. In some buildings, every space is highly significant and all changes must be taken with great care, under the guidance of an experienced preservation professional or team. Other buildings can accommodate greater change while still maintaining their historic character.
Buildings well matched to their tenants and functions require very little change. Whenever changing building occupancy or functions, seek uses and tenants suited to the building. Suitable uses are functions that minimize the need to alter character-defining features or spaces. The less modification required by the proposed program, the more suitable the program.
Accommodating new functions demands ingenuity. The success of which rests, to a great extent, upon the ability to successfully integrate old and new so that the property retains its historic character and the parts still relate to the whole.
In addressing changing space requirements, first consider options that enable the historic building to continue serving the function for which it was originally constructed. When the historic function is no longer viable, feasibility studies are undertaken to assess the financial and practical achievability of treatment options.
C. Design Development Stage
Design to Minimize Changes to Historic Property
Federal Courthouse, Scranton, PA. Adding an adjoining or freestanding annex has enabled many federal courts to remain in historic courthouse buildings, allowing continued public access to ceremonial courtrooms.
The underlying philosophy behind any preservation project is to keep to a minimum the proposed changes to a historic property. For its long-term protection, the historic property must always come first. Therefore, any changes should play a secondary role to the historic property and new work must not dictate what occurs on site. The role of the preservation design team or specialist is to help ensure that these changes contribute to, rather than detract from, a building's historic character and design unity.
If a historic property is on federal land or using federal funds and changes are proposed, the State Historic Preservation Officer (SHPO) in which the property is located must be consulted to comply with Section 106. The Secretary of the Interior's Standards provide the framework for responsible preservation design. Technical guidance is available to help resolve common preservation challenges.
For more detailed design guidance, refer to the following WBDG pages:
- Update Building Systems Appropriately
- Accommodate Life Safety and Security Needs
- Comply with Accessibility Requirements
- Sustainable Historic Preservation
Select Competent and Qualified Contractors

Similar to the selection of the project team, the construction team should consist of qualified contractors and subcontractors with experience working on similar historic properties. Select contractors early enough to include them in developing solutions that meet the project goals (where the contract process so permits).
GSA has developed contract language and evaluation criteria to verify the competency of architectural and engineering firms, as well as, construction contractors that propose to work on historic buildings. GSA's preservation project management online guidance also includes a model scope of services for architectural and engineering design work involving historic buildings. For more information, visit the GSA Historic Buildings website.
D. Construction Stage
Provide Temporary Protection
Construction activity during the course of a project can damage historic resources. Therefore, providing temporary protection of a building or site during this time should be incorporated in planning and construction documents. On-site supervision with regular inspections ensures that historic fabric is not at risk. For additional information on temporary protection see the National Park Service TechNote section on Temporary Protection.
Ensure Fire Safety During Construction
Many historic buildings are destroyed as a result of fires during construction. Fire-safe clean-up, including removal of flammable solvents and rags and debris, is critical. Fire suppression systems must be maintained and augmented when appropriate. Leave pathways to exits clear, and ensure that fire doors remain closed. Additional supervision may be required while high risk construction activities are underway.

Educate Workers and Public on Significance of Historic Property
Educating everyone involved in the project—from the property owner, to the consultants (architectural, structural, mechanical, plumbing, electrical, civil), to the contractors and laborers, and to the eventual property users—about why the property is worthy of preservation is vitally important. The better informed one is the more likely one is to treat the property with care.
Regular on-site supervision and good communication between the preservation team and the construction team can protect a historic building while construction is underway. Sometimes features worthy of preservation are uncovered as work progresses and this can ensure these and other important elements are not compromised.
Wayside signs or exhibits describing construction/preservation work can generate interest in the project while building good will among tenants and visitors who are inconvenienced by construction. The costs of these installations can be offset by reduced effort required to respond to questions and complaints.
Develop Building Maintenance Manual

For the long-term protection of a historic resource, operational guidelines should be developed for not only tenants, but also for the building staff. These guidelines should provide:
- Documentation on building systems
- Facilities management programs to record important information on the operation of a building or property
- Schedules for cyclical maintenance and custodial procedures
- Schedules for regular inspections of important features
- Guidance resources
E. Occupancy Stage
Modify Leasing Agreements and Provisions
Tenants must know what they can and cannot do prior to leasing. This type of information may be included in leasing documents and through the development of tenant guidelines.
Historic properties must also be protected when tenants move in or relocate to a property. Transporting furniture and office equipment can often cause damage unless care is taken to protect important features during increased levels of activity. Once again, accommodations for temporary protection should be made early on in the planning process and in construction documents.
Leases should also include procedural guidance for Section106 compliance when alterations are unavoidable.
Develop Special Events Policies
Historic buildings must be protected when special events are held. Former general post office/Hotel Monaco, Washington, DC.

Historic properties are often used for special events (e.g., exhibitions, exceptions, parties, demonstrations, etc.). These activities increase the wear and tear on a property and can damage an historic resource. Temporary protection of the architectural fabric and landscapes when equipment is moved in and out, and when the space is being used, should be provided. The following actions are recommended to minimize the effects of special events on the historic property:
- Confer with code officials to determine the types of activities that are appropriate for the space. Develop specific special events guidelines, noting that some activities are inappropriate for the property.
- Establish a permitting process when public or private buildings are leased for uses beyond their usual function, such as using a museum for a social event.
- Establish that lessees should submit in advance how they propose to use a historic property; some activities may be inappropriate.
- Determine beforehand who is responsible for protection and incidental damage as a result of leasing out a space. Consider mandatory security deposits.
- Ensure that the property (or lessee) is adequately insured to cover any damage.
- Ensure that appropriate on-site supervision is present throughout the event and clean-up.
Update Individual Preservation Management Plans
Technical guidance provided in the preservation management plans and other preservation plans should be periodically updated to ensure that the plans reflect current conditions. Updating also ensures that recommendations take into account technical advancements in treatment technologies that may have occurred since the plan was initially created. Updates should be undertaken by a specialist firm meeting the Department of Interior qualification standards, preferably by the firm who prepared the original plan.
While the concept of divesting of a historic property is anathema to historic preservation, changing missions and operations will often render historic properties excess to an organization's function. Any discussion concerning life-cycle costing is not complete unless the end of an asset's useful life is planned. Divestiture is the use of any authorized method to permanently remove the real property asset from the organization's inventory. Real property that is no longer required for current validated missions or established and authorized future missions will usually be identified as excess property and properly divested. In this regard, divesting of a property will be considered either by disposal in which the ownership of the property is transferred or by demolition in which the property is torn down, deconstructed, or otherwise destroyed. Within the Federal government, the divestiture process is highly regulated, documented, and controlled.
Generally the Federal government promotes the use of historic buildings. Disposal of a historic property is the preferred course of action if the building cannot be repurposed for an organization's reuse. Methods of disposal include the sale, exchange, or transfer of the real property. For instance, the National Historic Lighthouse Preservation Act (NHLPA) of 2000 (P.L. 106-355) permits historic lighthouse properties excess to U.S. Coast Guard needs may be transferred at no cost to other Federal agencies, state or local governments, nonprofit corporations, or community development organizations for educational, cultural, recreational, or historic preservation use.
While demolition of a historic property is usually not recommended, procedures are in place to regulate this activity. When alternatives to avoid adversely affecting historic and cultural properties are determined by the consulting parties not to be prudent and feasible, mitigation measures with the SHPO or THPO shall be developed to minimize the potentially adverse effect. Mitigation measures shall be appropriate to the nature and importance of the historic and cultural properties in question. In all cases, there will be preservation of such physical features as may be prudent and feasible. Such measures may include, but are not limited to:
- Modifying the proposed undertaking through redesign, reorientation of the project site, and other changes;
- Limiting the magnitude or extent of the proposed undertaking or identified alternatives;
- Rectifying the potentially adverse effects by rehabilitation, repairing, or restoring the affected resources;
- Compensating for the potentially adverse effects, for example, through the recovery and interpretation of scientific, prehistoric, historic, and archeological data; and
- Minimizing potential adverse effects over time through preservation procedures occurring throughout or subsequent to the undertaking.
Whenever an action may result in destruction or alteration of an historic property, the property will be properly documented prior to its alteration.
