Typical Provisions of the Ordinance

It is important to remember that a typical preservation ordinance "package" does all of these things: states a public purpose; creates a local preservation commission; designates historic districts and landmarks; sets out design criteria that govern commission design review; establishes a process for enforcing design review; and also establishes an appeal process for owners who are denied a "certificate of appropriateness." These components have been summarized below. Note that there are special rules for a Certified Local Government's ordinance.

Public Purposes. The ordinance lists the public purposes served by the adoption of the preservation ordinance, including the promotion of aesthetic and architectural values, civic-mindedness or cultural education; the safeguarding of historical and cultural heritage; the improvement or stabilizing of property values; the enhancement of tourism or other types of business; the strengthening of the local economy; the encouragement of cultural diversity, or the provision of recreational amenities. The purposes section is important because it provides general direction for the implementation of the law. When an unforeseen situation arises and specific requirements do not exist or do not seem applicable, look to the purpose section for general guidance.

Creation of the Local Preservation Commission. The ordinance creates a local preservation commission (often described as a landmarks commission, historic district commission, or board of architectural review) to administer the preservation ordinance. Commission members may be required to provide expertise within the diversity of professions bearing upon preservation concerns, such as law, architecture, history, archaeology, real estate, and engineering. Some ordinances have district residency requirements, and many specify an odd number of members to avoid the risk of a tie in voting. The ordinance outlines the scope of the commission's powers, including its power to adopt procedural rules (e.g., open meetings, conflicts of interest, etc.), its authority to hire staff, and possibly its opportunity to receive funding from non-government sources. Ordinances often require the commission to record minutes of its meetings and provide annual reports. Ordinances also usually describe the process for appointing commission members and the duration of the term of appointment.

Designation of Historic Districts and Landmarks. The ordinance requires the commission to conduct a "study and survey" of local historic (and sometimes prehistoric) resources and to maintain an inventory of the survey results. The ordinance also requires the maintenance of a list of those surveyed properties that the local government has chosen to designate with all of the associated benefits and restrictions. It also specifies the designation procedures for historic districts and landmarks, as well as boundary descriptions relating to that selection, and lists significance criteria a property or district must meet in order to be designated. The ordinance then describes the mechanics of designation, including application procedure, provision for notification of owners or other interested persons, public hearings prior to the designation decision, and notification of the ultimate decision. Because a careful evaluation of significance takes time, the ordinance may also impose a moratorium on applications for alteration or demolition while the application for designation is pending. Establishing common criteria for historic resource evaluation is a central objective. Local officials are therefore encouraged to ensure that preservation ordinances incorporate these criteria and standards. Many local ordinances contain criteria of significance that are based on those used for the National Register of Historic Places. In some instances, official local designation involves an amendment to the local ordinance specifically mentioning the historic district. Other kinds of ordinances just describe the mechanism for local designation.

Certificates of Appropriateness. The ordinance requires that prior to material changes or major alterations to a designated historic resource, the commission or other local entity (such as a planning commission or city council) must approve a certificate of appropriateness. Maintenance, such as painting, caulking, and other minor repairs and targeted replacement in kind, usually does not require such a certificate). To make the ordinance understandable to property owners, it should carefully define the term or terms that trigger the need for the certificate, e.g., building/landscape alterations, new construction, etc.; the criteria for design review employed for the issuance of a certificate; the opportunity for a public hearing; and notification to the owner of the reviewing body's decision. To defuse potential takings and due process problems, ordinances should provide owners with an opportunity to claim economic hardship, and to require the reviewing body to prepare detailed findings supporting its decision on a certificate of appropriateness.

Demolition Applications. Preservation ordinances vary in their descriptions of a commission's ability to participate in the process for reviewing an application to demolish a locally designated historic resource. The strongest ordinances provide the authority for outright denial of demolition applications. Many others authorize the commission to impose a delay of proposed demolitions to facilitate additional study and public review, while a weaker type of ordinance simply authorizes a commission to make comments prior to demolition. Even where the ordinance only authorizes delay rather than denial of a demolition permit, that commission "discretion" is likely to be sufficient to provide enough time to consider economically feasible alternatives to demolition. Open and informed decisionmaking is what is being sought here, as well as for every instance of design review.

Some ordinances require consideration of post-demolition plans for the same site before the granting of a demolition permit. Some of the same considerations discussed in connection with certificates of appropriateness also apply to review of demolition applications, including the need for careful specification of review criteria, economic hardship provisions, and detailed findings.

Government-Owned Property. Some ordinances also require commissions to develop and maintain registers of significant government-owned properties, including those that are designated landmarks or within historic districts. These ordinances may require the agency owning the property to seek the advice of the commission before approving significant alteration, demolition of the property, or any other action that might have an impact on the historic district.

Maintenance of Historic Properties. The preservation ordinance often includes some requirement of minimum maintenance for designated historic resources, designed to control deterioration that leads to "demolition by neglect." Minimum maintenance provisions need to clearly specify what is required of property owners. In addition, ordinary maintenance of historic properties is often exempted from the requirement for a certificate of appropriateness. This and other consequences of local designation should become a part of the property's title information, so that new owners have adequate notice of their responsibility.

Enforcement. Enforcement provisions are needed to ensure that a commission's authority (whatever it is) under a preservation ordinance is binding. In other words, the ordinance should describe the consequences of failure to follow the law or legal decisions made pursuant to the law. The ordinance may establish specific penalties for violation or provide for civil remedies. Although these provisions may appear within the preservation ordinance, the ordinance is sometimes part of a larger zoning code that contains enforcement provisions. Local governments and landowners should be aware that in extreme cases the courts have validated a sanction requiring unauthorized demolitions to be rebuilt.

Appeal. In many cases, the ordinance allows a property owner to appeal to another local decision-making body a decision denying a certificate of appropriateness or a demolition application, with the final determination generally provided by the elected city council or county board of supervisors. The ordinance should specify the procedures and timing governing the appeal, and whether the entity deciding the appeal should be allowed to consider new evidence. The ordinance should clearly indicate what constitutes a final decision, so that interested parties will know when a decision is appropriate for judicial review.

Moratoria and Emergency Measures. Because time is often required before a local preservation commission or appeal body can carefully complete its review of a designation decision or a demolition application, a problem arises if the owner seeks to destroy or materially alter the property at issue while that determination is still pending. Moratoria are imposed to provide a period in which the consideration of designation or demolition application can occur free of concern about potential damage to the property.

In addition, local jurisdictions sometimes specify a defined time period in which the commission is authorized to delay demolition and therefore permit further study. In general, preservation moratoria are likely to be upheld where they are of definite sduration. By contrast, moratoria that fail to provide reasonable time limits are likely to be invalidated as violating due process requirements

Severability Clause. Many ordinances have a severability clause, which allows the ordinance as a whole to remain in effect even if a court has problems with a specific provision.
