Preservation Easements and How Long They Bind
An easement is the one preservation instrument an owner creates voluntarily and cannot later repeal. It is recorded against the title, it binds every successor in ownership, and the organization holding it carries a standing duty to enforce it.
The rule in short
A preservation easement is a recorded interest in real property conveyed to a government body or qualified charitable organization, restricting alteration and demolition and reserving to the holder rights to inspect, approve changes and enforce. Where a deduction is claimed, 26 U.S.C. 170(h) requires a qualified real property interest granted to a qualified organization exclusively for conservation purposes and protected in perpetuity.
A preservation easement is a promise written into the title. The owner conveys to a holder the right to prevent specified changes to a building, the holder records the deed, and every future owner takes the property subject to it. Unlike a municipal designation, no later council can repeal it, and unlike a listing, it directly restricts what the owner may do.
What the instrument actually is
Despite the name, the interest conveyed is negative rather than affirmative. The holder does not gain a right to use the property. It gains a right to prevent the owner from doing things, together with rights of inspection and approval that make the prevention workable. Most states have adopted enabling legislation that removes common law obstacles to such interests, so that an easement may be held in gross by an organization owning no neighboring land.
The rights reserved to the owner are as important as the restrictions imposed. A well-drafted deed states what the owner may do without permission, what requires the holder's written approval, and what is prohibited outright. It also states the standard the holder will apply when reviewing a request, and whether approval may be withheld unreasonably. Deeds that simply prohibit alteration without describing an approval mechanism make ordinary repairs into negotiations.
The scope is a matter of drafting. A facade easement restricts the exterior surfaces the deed describes, commonly the front and any elevation visible from a public way, and sometimes the entire exterior envelope including height and massing. A whole-building easement extends to significant interior spaces and features. A land easement protects a historically important setting rather than a structure.
The holder's duties
An easement without a monitoring holder is a document rather than a protection. Holders typically inspect on a fixed cycle, photograph conditions, review and approve or reject proposed alterations, keep the file, and act when a violation appears. Deeds usually grant a right of entry on notice for exactly this purpose.
Holders also charge for the service, and the mechanism varies. Some require a one-time stewardship contribution calculated on the expected cost of perpetual monitoring. Some take an endowment gift alongside the easement. Some charge review fees for each application. An owner comparing holders should ask how the monitoring is funded, because a holder relying on annual fundraising to inspect an easement it will hold forever has an obvious structural weakness.
Enforcement remedies are those of an equitable interest in land: injunction against work in progress, specific performance, and restoration of what was altered. Damages are an awkward fit, because the loss is to the public interest the restriction serves rather than to the holder's own economic position. That is why deeds routinely provide for restoration and for recovery of the holder's costs.
At the time of conveyance the parties prepare and sign a description of the property's condition: photographs of every regulated elevation, plans, and a narrative of features. Without it, an argument years later about whether a cornice was original or whether a window was already vinyl becomes unwinnable for the holder. Owners have the same interest in an accurate baseline, because it protects them from being asked to restore something that was never there.
The requirements where a deduction is claimed
Where the easement is donated and a charitable deduction is claimed, section 170(h) of the Internal Revenue Code sets conditions. There must be a qualified real property interest, conveyed to a qualified organization, exclusively for conservation purposes, and the conservation purpose must be protected in perpetuity. Preservation of a historically important land area or a certified historic structure is an enumerated conservation purpose.
Valuation is the other half of the deduction question and the half that generates disputes. The value of the contribution is generally the difference between the value of the property unrestricted and its value subject to the restriction, established by a qualified appraisal. Where the property was already subject to a local ordinance restricting the same features, the incremental restriction the easement adds may be small, and appraisals that ignore the existing regulation have been the recurring problem in this area.
The regulation adds requirements that matter in drafting. Any mortgage must be subordinated so that a foreclosure cannot extinguish the restriction. For a building in a registered historic district, the restriction must preserve the entire exterior, including front, sides, rear and height, and must prohibit changes inconsistent with the historic character. A written agreement must certify that the holder is qualified and has the resources and commitment to enforce, and specified documentation must accompany the return.
| Instrument | What is restricted | Who holds it | Typical duration | Deduction available? |
|---|---|---|---|---|
| Facade easement | Described exterior elevations, sometimes height and massing | Government body or qualified charity | Perpetual where drafted for a deduction | Yes, if the statutory conditions are met |
| Whole-building easement | Exterior plus identified interior spaces and features | Government body or qualified charity | Perpetual | Yes, on the same conditions |
| Historic land easement | Setting, viewshed, archaeological deposits, development rights | Land trust or agency | Perpetual | Yes, as a historically important land area |
| Grant or credit covenant | Whatever the funding agreement specifies | The granting agency | A stated term of years | No, it is consideration for funding |
| Mitigation easement in an agreement | Features identified in the consultation record | Preservation officer or designated holder | As stipulated, often perpetual | Generally no, it is required rather than donated |
Durability against later owners
Recording is what gives the easement its reach. A purchaser takes with record notice, and the restriction is enforceable against that purchaser whether or not anyone mentioned it at closing. Subordination extends the same result to a lender's foreclosure sale. This durability is precisely why easements appear as mitigation in federal agreements, a use described in adverse effect findings and the mitigation that follows.
The trade for durability is inflexibility. An owner who wants a different outcome must ask the holder to approve it under whatever discretion the deed reserves, and where the deed reserves none, the answer is no. Owners weighing an easement against other routes should compare it with the repealable municipal controls described in local designation and certificates of appropriateness, with the entirely non-restrictive status explained in what a federal listing does and does not restrict, and with the term-limited covenants that accompany the incentive discussed in the rehabilitation credit and its certification steps.
Points to carry away
- The easement is recorded and binds every later owner, including a purchaser at foreclosure.
- The holder must have the commitment and resources to monitor and enforce the restriction.
- A deduction under 26 U.S.C. 170(h) requires the restriction to run in perpetuity.
- Baseline documentation records the condition the easement is measured against.
- Existing mortgages must be subordinated for a qualified conservation contribution.
- Amendment or extinguishment normally requires a judicial proceeding rather than agreement alone.
Questions readers ask
Who can hold a preservation easement?
A government unit or a charitable organization that meets the requirements for a qualified organization, and that has both the commitment to protect the conservation purposes and the resources to enforce the restrictions. The second half of that test is the practical filter. An organization with no monitoring program and no reserve for litigation cannot honestly certify that it can enforce, and easements conveyed to such holders have produced the most difficult cases. Owners should ask a prospective holder how many easements it monitors, how often, and what it has done when a violation occurred.
What happens if the holder organization dissolves?
A well-drafted easement anticipates this and names a successor or provides for transfer to another qualified holder, often with the consent of a state officer. Where the deed is silent, the disposition falls to state law and usually to a court, which may direct the interest to a similar organization. The gap between dissolution and transfer is the dangerous period, because nobody is monitoring and violations accumulate. Nothing about the holder's disappearance extinguishes the restriction itself, and a later owner who assumes otherwise is exposed.
Can an owner get an easement removed because circumstances changed?
Rarely, and not by agreement with the holder alone. Where the easement is drafted to satisfy the perpetuity requirement, it typically provides that extinguishment may occur only by judicial proceeding on a finding that the conservation purpose has become impossible or impractical, with the holder entitled to a proportionate share of any proceeds. Courts have been unreceptive to arguments that a neighborhood changed or that the building became inconvenient. The remedy an owner actually has is to seek the holder's approval for the specific change, within whatever discretion the deed grants.

Listing on the National Register: Criteria and Process
Under 36 CFR 60.4 a district, site, building, structure or object qualifies for the National Register if it possesses integrity and meets one of four criteria: association with significant events, association with significant persons, distinctive design or construction, or the capacity to yield important information. Nominations travel through the State Historic Preservation Officer and a state review board to the Keeper, and 36 CFR 60.6 gives a private owner an objection that blocks listing.
Federal Undertakings and What Triggers Review
Under 36 CFR 800.16(y) an undertaking is a project, activity or program funded in whole or in part under the direct or indirect jurisdiction of a federal agency, carried out by or on behalf of an agency, carried out with federal financial assistance, or requiring a federal permit, license or approval. Section 800.3 requires the agency to decide first whether an undertaking exists and then whether it is the type of activity with potential to cause effects on historic properties.
The Consultation Sequence and Its Agreement Documents
Subpart B of 36 CFR Part 800 sets out four steps: initiation under 800.3, identification of historic properties under 800.4, assessment of adverse effects under 800.5, and resolution under 800.6. The preservation officer, Indian tribes, local governments, the applicant and interested members of the public are consulting parties. Resolution normally ends in a memorandum of agreement, or in a programmatic agreement for complex or repeated undertakings.
