Exeter — Historic Preservation
Historic Preservation under the Exeter local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
Exeter’s historic-preservation rules are codified in the H‑X (Historic Overlay) chapter of the local zoning ordinance (Title 17). The H‑X chapter creates a local register, establishes a five‑member Historic Preservation Commission, sets criteria for designation of cultural resources, historic districts and areas of historic interest, and requires Commission review for most alterations, demolitions or relocations of designated resources. Key procedural triggers include petition thresholds, public‑hearing notice and a 60‑day Council review window for new designations. § 17.44.01–17.44.25 .
Note: Exeter treats the H‑X as an overlay that attaches to an underlying base zone (e.g., H‑R‑1 and H‑RM‑3) so permitted uses and base development standards remain those of the underlying zone unless the preservation designation says otherwise. § 17.44.02
How Exeter’s rules work (chapter-level synthesis)
- Purpose and scope: The H‑X overlay is intended to protect cultural heritage, preserve neighborhood character, and encourage compatible infill while involving citizens in planning historic neighborhoods. § 17.44.01
- Applicability: The H‑X overlay may be combined with any residential, office, or commercial base zone; established H districts are suffixed with the base zone (example: H‑R‑1‑6, H‑RM‑3). Permitted and conditional uses default to the underlying base zone. § 17.44.02–17.44.04
- Commission & process: A five‑member Historic Preservation Commission is appointed by City Council to survey properties, recommend designations, adopt guidelines, and review alteration/demolition applications. Commission decisions are appealable to City Council. § 17.44.07–17.44.08; § 17.44.15–17.44.16
- Public participation & notices: Designation hearings require published notice and mailed notice to property owners and to owners within 300 feet for cultural-resource or district actions. § 17.44.13; § 17.44.14
- Work moratorium during designation: After owners are notified of a pending designation hearing, a temporary moratorium applies to alterations/demolition of the subject property while proceedings are pending (with narrow safety exceptions). § 17.44.14
- Standards for alteration/demolition: Alterations/demolitions/relocations of designated cultural resources or properties within historic districts generally require Commission approval; approval criteria require that proposed work will not adversely affect architectural features, special character or relationship with neighboring resources. Demolition may be allowed only for limited reasons (public hazard, public use, or proven unreasonable economic hardship per the code). § 17.44.20–17.44.22; § 17.44.24
- Secretary of the Interior’s Standards: Preservation plans and treatments are expected to generally follow the Secretary of the Interior’s Standards where noted in the code. § 17.44.15; § 17.44.15 (preservation plan def.)
Practical note: Because the H‑X is an overlay, plan reviewers will check both the H‑X chapter and the underlying base zone and development standards; see Exeter’s development standards and the overlay districts overview for context.
District-by-district breakdown (how H-X attaches to base zones)
The ordinance defines the overlay rather than a single fixed historic zone. Below are Exeter‑specific overlay combinations that the code explicitly uses as examples; for each, permitted uses follow the base zone and dimensional rules are taken from the base zone unless the H‑X designation or preservation plan modifies them.
H‑R‑1 (Historic overlay combined with R‑1 single‑family zone)
- Purpose: Preserve single‑family historic neighborhoods while keeping R‑1 uses. § 17.44.02
- Typical permitted uses: Uses listed for the R‑1 base zone (single‑family homes and accessory uses); the H‑X does not add new base uses. § 17.44.03
- Key dimensional standards: The H‑X chapter defers to the underlying R‑1 standards for setbacks, height, lot coverage and parking unless a preservation plan amends them. Specific R‑1 numeric standards are in the base‑zone sections (Not found in retrieved materials; verify with the city’s development standards). § 17.44.02–17.44.03
- Where it applies: Any area formally designated by Commission/Council and recorded; designation is added to the Exeter Register of Historic Places. § 17.44.16–17.44.17
H‑RM‑3 (Historic overlay combined with RM‑3 multifamily zone)
- Purpose: Protect multi‑unit historic resources and neighborhood character while preserving housing uses. § 17.44.01–17.44.02
- Typical permitted uses: Uses listed in the RM‑3 base zone (multi‑family residential, accessory dwelling units where allowed by state/local ADU rules). Check Exeter ADU provisions when working on conversions: see ADUs. § 17.44.03
- Key dimensional standards: Base‑zone RM‑3 standards control unless a preservation plan modifies them (specific RM‑3 numeric standards Not found in retrieved materials; verify with development standards). § 17.44.02
- Where it applies: Properties within a designated historic district or as individually designated cultural resources listed on the Exeter Register. § 17.44.05; § 17.44.17
Practical guidance: Whenever the H‑X overlay is present, check both the H‑X designation resolution and the underlying base‑zone numeric standards (setbacks, height, lot coverage, parking). Parking rules are still governed by base‑zone standards and the city’s parking rules unless the preservation plan states otherwise. § 17.44.03

Information gaps (what the ordinance excerpts in the retrieved materials do not show)
- Numeric dimensional standards (exact setbacks, heights, lot coverage, and FAR) for R‑1, RM‑3, and other base zones — Not found in retrieved materials; verify in the base‑zone sections or development standards. § 17.44.02–17.44.03
- Exact list of the Exeter Register entries (the local list of designated properties) — Not found in retrieved materials; check city clerk or Commission records. § 17.44.05; § 17.44.17
- Whether the H‑X overlay creates any numeric parking reductions or automatic design‑review exemptions — Not found in retrieved materials; verify with parking and the city’s design review procedures. § 17.44.03
- Any formal fee schedule amounts for designation or appeals — Not found in retrieved materials; the code states fees are charged but not the amounts. § 17.44.10(C)
Checklist — what an applicant must satisfy for a designation or an alteration/demolition review
- Submit a complete designation or alteration application on city forms with required materials (legal description/address, photographs/sketches, statement of condition, explanation of threats) and the processing fee. § 17.44.10(C); § 17.44.11(C)
- For a proposed historic district, secure a petition signed by owners of at least two‑thirds (2/3) of parcels in the proposed district and include a preservation plan. § 17.44.11(B–C)
- Provide any additional documentation requested by staff so the application is complete (plans, drawings, cost estimates if claiming hardship). § 17.44.23(F); § 17.44.24
- Be prepared for public notice and hearing: mailed notices to owners within 300 feet and published notice at least ten days prior. § 17.44.13; § 17.44.20(C)
- If proposing alteration/demolition, demonstrate the proposal meets approval criteria (no adverse effect on architectural features, special character, and congruity) or prove unreasonable economic hardship for demolition. § 17.44.21–17.44.24
- If the property is within an H‑X overlay, check whether the preservation plan modifies development standards (setbacks, signage, parking). Verify with signage and the development standards. § 17.44.05; § 17.44.15
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Base‑zone numeric standards not stated in H‑X chapter | The H‑X defers numeric standards to the base zone; whether a project meets setbacks/height/coverage cannot be determined from H‑X alone | Confirm base‑zone numeric standards (R‑1, RM‑3, C‑zones) in the zoning chapters or development standards. Not found in retrieved materials. § 17.44.02–17.44.03 |
| Whether proposed minor repairs are exempt from Commission review | Code lists examples of exempt improvements but allows City Planner or Head Building Official discretion, creating project‑specific ambiguity | For each project obtain a written pre‑application determination from planning staff. § 17.44.20(B) |
| Proof of "unreasonable economic hardship" standard | Owner bears the burden and must supply detailed financial data; lack of clear numeric threshold means dispute risk | Prepare full financial package per the code (market value, rehab costs, taxes, debt service) and expect staff/Commission scrutiny. § 17.44.24 |
| Local register contents and boundaries | Property‑specific rights and obligations depend on whether a property is actually listed or within a recorded district | Verify property status on the Exeter Register of Historic Places and review the recorded designation resolution and map. § 17.44.05; § 17.44.17 |
Plain‑English summary
Exeter’s H‑X Historic Overlay chapter sets up a Historic Preservation Commission and a local historic register, requires public hearings and mailed notice for designations, and generally requires Commission approval before you alter, move or demolish a designated historic property; demolition is only allowed for narrow reasons (public hazard, public use, or proven economic hardship). § 17.44.07; § 17.44.20–17.44.22; § 17.44.24

Frequently asked questions
What triggers Commission review for work on my Exeter property?
Most proposed alteration, demolition or relocation of a designated cultural resource or property within a designated historic district requires approval by the Historic Preservation Commission before a permit is issued. There are limited exemptions for work that does not affect specified exterior features, but the default is Commission review. § 17.44.20–17.44.21
How is a historic district designated in Exeter?
A designation may be initiated by the City Council, the Historic Preservation Commission, or property owners; district petitions must be signed by owners of at least two‑thirds (2/3) of parcels in the proposed district and include a preservation plan and documentation. The Commission holds a public hearing and the Council makes the final decision (Council acts not less than 60 days after the Commission recommendation). § 17.44.11; § 17.44.15–17.44.16
If my building is under consideration for designation, can I still get a building permit?
Once the owner is notified of a pending designation hearing, the code imposes a temporary moratorium on approvals for alteration, demolition or removal of the subject property while designation proceedings are pending, except where immediate action is required for safety or where Council delay exceeds 60 days and work would not harm proposed resources. § 17.44.14
What evidence is required to justify demolishing a designated historic building?
Demolition is permitted only when at least one of the code’s narrow grounds is met: the structure is a public‑safety hazard and repair is impractical, the site is needed for a greater public use, or denial would cause unreasonable economic hardship to the owner; the applicant bears the burden of proof and must submit detailed financial and property evidence. § 17.44.22; § 17.44.24
Do preservation plans change development standards like setbacks, parking or signage?
A preservation plan can include restrictions or modifications (height/area/signage/parking) appropriate to the proposed historic district, but by default the H‑X defers to the underlying base zone for permitted uses and dimensional standards. Always check the preservation plan resolution and the underlying base‑zone chapters; numeric base‑zone standards are not printed in the H‑X chapter. § 17.44.03–17.44.05; § 17.44.15
Who serves on the Historic Preservation Commission and what are its powers?
The Commission is a five‑member volunteer body appointed by City Council, with duties that include surveying properties, adopting designation guidelines, maintaining the local register, reviewing alteration/demolition applications, and recommending nominations to state or national registers. § 17.44.07–17.44.08; § 17.44.19
If my property is not yet designated but is in an "area of historic interest," do I need Commission approval to renovate?
Work within an "area of historic interest" should be done with respect to the area's character and the Commission can act as a resource; however ordinary maintenance/repair that does not require a permit is not prevented by the code. For permit‑required work, the Commission’s guidance is advisory unless the property is formally designated. § 17.44.23
Can the city nominate a property for the State or National Register?
Yes. The City Council may request the Commission to nominate a site for inclusion on the State or National Register following the city’s designation procedures. § 17.44.19
Are there exemptions for minor mechanical or interior work?
The code lists examples of improvements that can be exempt from Commission review (e.g., some mechanical, reroofing not visible from the street, pools not in viewshed), and the City Planner or Head Building Official may grant additional exemptions at their discretion. However, exemptions cannot affect designated architectural features or the special character as specified in the designation. § 17.44.20(B); § 17.44.20(D–E)
What happens if the Commission denies my alteration application?
Commission denials must be supported by written findings and are mailed to the applicant; appeals of the Commission decision may be filed with the City Council within ten calendar days of mailing the decision notice and will be set for a public hearing. § 17.44.20(G–H)
