Corning — Historic Preservation

Last reviewed: July 1, 2026

Overview

Corning’s Zoning Code (Title 17) does not appear to contain a standalone “historic preservation” chapter; instead, historic resources are handled by references and special rules scattered through Title 17 (zoning), the floodplain combining district, and the development/overlay rules. That means historic properties are treated as a factor that can limit ministerial approvals (urban lot splits, two‑unit developments), trigger discretionary review or use/variance processes, and qualify for special variance relief in floodplain situations. See § 17.04.010 for the Zoning Code title and scope.

How the Corning code treats historic resources — district-by-district

Note: every bolded district name and every code reference below is taken from Corning’s Title 17 (Zoning Code). Where a code fragment mentions “city landmark” or “historic district” the code text treats those designations as showstoppers for certain ministerial/streamlined entitlements but I did not find a separate city procedure for landmark designation in the retrieved materials (see Information Gaps).

P-Q (Public or Quasi-Public Use District)

• Purpose: the P-Q district is to accommodate public, institutional and cultural uses and to allow site-plan/site approval for compatibility § 17.33.010.
• Historic-specific rule: Historical sites are explicit uses permitted subject to a use permit in the P-Q district § 17.33.030. That means a property zoned P‑Q may host a museum or preserved historic site under discretionary review (use permit) rather than by-right.
• Typical permit pathway: discretionary use permit (public hearing/conditions) — see § 17.33.030.
• Where it applies: mapped P‑Q parcels per the city zoning map; see zoning overview.

FP (Floodplain Combining District)

• Purpose: the FP combining district regulates development in floodplains and applies supplementary rules where it is combined with base zones § 17.45.030–040.
• Historic-specific rule: the FP variance provisions explicitly allow variances for reconstruction/rehab/restoration of structures listed on the National Register or State Inventory — i.e., historic structures qualify for special variance consideration § 17.45.190(G)(1). The chapter then requires the variance be the minimum necessary and not increase flood impacts § 17.45.190(G)(2–5).
• Practical effect: If a designated historic building sits in an FP area, the Planning Commission may grant a variance for work that preserves historic character even where standard flood rules would otherwise prohibit the change — but the variance is limited and must show minimum necessary relief § 17.45.190.

R-1 and single-family residential zones (where ADUs / two-unit / urban-lot-split rules apply)

• Purpose & dimensional rules: R-1 (and related single-family districts) set the base residential rules and list Accessory Dwelling Units as allowed subject to Chapter 17.64; see § 17.10.020(J) and the R‑1 development standards table in § 17.10.040.
• Historic-specific limits:
  • Two‑unit development (ministerial, state‑law implementation) is prohibited on parcels that are in a historic district, listed on the state historic resources inventory, or designated/listed as a city landmark or historic property § 17.71.040(E); applicants must also file occupancy history affidavits and record covenants § 17.71.060. This means two‑unit ministerial approvals are ineligible for properties that are historic § 17.71.040(E–F).
  • Urban lot splits (ministerial parcel split for up to two lots) likewise exclude parcels that are in a historic district or listed on the State Historic Resources Inventory or listed as a city landmark/historic property § 17.70.040(F); the ministerial process is described at § 17.70.030.
• Practical effect: owners in R‑1 who have a designated historic property cannot use the streamlined two‑unit or urban-lot-split paths; they must pursue discretionary routes (if available) or be ineligible.

SPMU / CBZ / specific-plan / corridor overlays

• Purpose: overlays like SPMU (Specific Plan Mixed‑Use) and the Highway 99W corridor (Corning Business Development Zone / CBZ) layer design expectations and visual guidelines on top of base zoning § 17.49.010–030; § 17.53.020–040.
• Historic-specific rule: overlay districts typically require that design be consistent with corridor visual/design guidelines; these overlays can make design review and site‑plan requirements applicable to historic or adjacent properties § 17.49.030(C). That means historic status does not remove overlay design rules; rather it can create overlapping review expectations.

Quick decision‑table (most decision‑relevant standards / uses)

Checklist

• Identify whether the property is in a historic district or listed as a city landmark or on the State Historic Resources Inventory — the Corning code treats any of those designations as disqualifying for several ministerial paths § 17.70.040(F) and § 17.71.040(E).
• Check your base zone (e.g., R‑1, P‑Q, overlay like SPMU) and applicable development standards at § 17.10.020 and the residential table § 17.10.040; consult Corning Development Standards.
• If you propose a historical site use on P‑Q, prepare for a discretionary use permit (public hearing/conditions) per § 17.33.030.
• If located in the FP floodplain and the resource is listed on the National Register or State Inventory, evaluate variance eligibility under § 17.45.190(G) and prepare technical flood and structural documentation.
• If you planned an ADU, two‑unit development, or urban‑lot split: confirm the historic‑status exclusion in § 17.71.040 and § 17.70.040 before relying on ministerial review.
• If your site falls in an overlay (SPMU, CBZ, Highway 99W), prepare visual/design documentation consistent with corridor guidelines § 17.49.030(C) and § 17.53.040 and expect site/design review.
• For any variance/conditional use application, follow the application and hearing rules in Chapters 17.58 and 17.54; variances have public‑hearing and findings obligations § 17.58.020–030; § 17.54.030.

Risks & Ambiguities

Information Gaps

• No discrete “Historic Preservation” chapter located in the retrieved Title 17 files — the code references city landmarks/historic districts but does not show the designation process, local landmark criteria, or a local register/map in the retrieved materials. Not found in retrieved materials.
• No ordinance text recovered that explains how a structure becomes a "city landmark" (what body designates, findings required, appeal process). Not found in retrieved materials.
• No local historic‑resource design review standards or guidelines specific to historic buildings located in the retrieved material (there are general design guidelines for Highway 99W and overlays, but not a local historic design guideline). Partial: overlay visual guidelines exist § 17.53.040, but a formal historic design guideline or secretary standards adoption is not found.

Plain-English Summary

Corning’s zoning code treats historic properties as a special status that can block certain “streamlined” approvals (urban lot splits, two‑unit ministerial approvals), makes historic sites a discretionary use in the P‑Q district, and gives the Planning Commission authority to grant limited variances in the floodplain to preserve historic buildings — but the code fragments retrieved do not include a separate local landmarking procedure or a local historic resources register. Always confirm a parcel’s historic status with the City before assuming you can use a ministerial path (see § 17.70.040, § 17.71.040, § 17.45.190).
