Historic Preservation Easements  

Historic preservation or facade easements play a crucial role in protecting properties of historical significance by restricting certain modifications and uses. While these easements serve
the public interest by preserving cultural heritage, they also introduce unique challenges for property appraisers. Understanding the valuation implications of historic preservation easements is essential for accurate and fair property appraisals.

A historic preservation easement is a legal agreement between a property owner and a qualified organization—such as a government entity or nonprofit preservation organization—that restricts alterations to a property’s historical features. These easements are typically permanent and run with the land, meaning future owners are also bound by the restrictions.

The primary purposes of these easements include:

• Preserving architectural integrity
• Maintaining historical authenticity
• Preventing demolition or inappropriate modifications

These restrictions can significantly impact a property's marketability, usability, and ultimately, its value.

Impact of Preservation Easements on Property Value

1. Marketability & Demand
   Properties with historic preservation easements may appeal to niche buyers who value historic integrity. However, these properties often have a smaller market due to the restrictions, potentially leading to longer marketing times and lower market demand.
2. Use & Development Restrictions
   The easement may prohibit modifications that would otherwise enhance the property's functionality or market appeal. For example, a property owner may be unable to expand a structure, replace historic materials with modern substitutes, or make energy-efficient upgrades that alter the property's historic character.
3. Tax Benefits & Incentives
   In some cases, property owners may receive tax deductions for donating an easement, based on the value of the rights relinquished. Additionally, historic properties may qualify for grants or tax credits, which can partially offset the financial burdens associated with preservation requirements.

Appraisal Methods

1. Sales Comparison Approach

The most commonly used method, this approach relies on recent sales of comparable historic properties with similar easement restrictions. When direct comparables are unavailable, appraisers must make adjustments for differences in easement severity, location, and market conditions.

2. Income Approach

For income-generating properties, the income approach considers the impact of restrictions on rental income and expenses. Easement constraints may limit a property’s ability to generate income by restricting alterations that could attract higher-paying tenants or commercial use changes.

3. Cost Approach

This approach estimates the cost to reproduce or replace the historic property while accounting for depreciation and the constraints imposed by the easement. However, since historic properties often have unique construction methods and materials, estimating replacement costs can be complex and costly.

Appraising properties with historic preservation easements requires specialized knowledge of historic property valuation, easement restrictions, and market dynamics. While these easements protect valuable cultural assets, they also introduce complexities that impact property values.
