Hemet — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

This page summarizes what the City of Hemet's development code allows and limits for nonconforming lots, land uses, structures, and improvements (what the code calls "legal nonconforming" items). It interprets the local rules you must follow to keep, repair, rebuild, expand, or lose the right to a nonconforming condition under Hemet's code (not state building standards or tenant law). Key local rules live in the Hemet Development Code divisions addressing nonconformities: § 90‑55 through § 90‑60 and § 90‑59 (nonconforming structures) among others.

(Note: for background on how these rules interact with things like parking, setbacks and ADU permitting see Hemet Parking, Hemet Development Standards, and Hemet ADUs.)

What the code says — essentials and how they apply

• Legal nonconforming status exists when a lot, use, structure or improvement was lawfully established before the code change that created the nonconformity. The general purposes and applicability are described at § 90‑55 and § 90‑56.
• A nonconforming land use may be continued but will be lost if abandoned or discontinued per the abandonment rules (commonly 180 days for most uses). See § 90‑58.
• Nonconforming structures may be repaired, rebuilt, or in some cases enlarged subject to limits (not to increase the discrepancy with current standards); special rebuild thresholds and public‑hearing requirements apply when damage exceeds 50% of fair market value. See § 90‑59.
• Nonconforming nonresidential uses may be allowed a one‑time area expansion of 25% if approved via a conditional use permit and findings are met. See § 90‑271 and related subsections.

Below are the most decision‑relevant standards in tabular and district formats so you can quickly apply them to a Hemet parcel.

Quick reference table — core nonconforming rules

District-by-district guidance (what nonconforming rules mean by zone)

Below are Hemet district names and how the nonconforming rules most directly interact with them. Where possible the actual Hemet district labels and development references used in the code are shown in bold and tied to the ordinance sections cited. For dimensional standards and measurement rules see Hemet Development Standards and the site‑development rules at § 90‑386.

R-1-10 (single‑family)

• Purpose / where it applies: standard single‑family residential lots in Hemet; the code explicitly references R-1-10 when describing allowed treatment of nonconforming single‑family dwellings.
• Typical permitted uses: single‑family dwellings (code treats a continuously used single‑family home as a special nonconforming residential case). Verify with the jurisdiction for parcel‑specific allowed uses.
• Key nonconforming rules that matter to owners:
  • If the single‑family dwelling is nonconforming as to location within a zone that does not permit single‑family, the dwelling shall be subject to R‑1‑10 regulations for additions. § 90‑59(8)(a)(3)
  • Additions: up to 25% enlargement of original enclosed floor area is permitted (subject to other code rules). § 90‑59(8)(a)(2)
  • Continuation of a nonconforming side yard is allowed for single‑family additions if the addition maintains an equal or greater setback and is no taller than 14 ft. § 90‑59(8)(b)
• Interaction with setbacks and development standards: additions must meet the development code provisions applicable to R‑1‑10; refer to Hemet Development Standards for exact setback tables. (See Hemet Development Standards.)

R-2, R-3, R-4 (multiple‑family residential)

• Purpose / where it applies: multiple‑family housing districts; Hemet's minimum development table for these zones (e.g., unit sizes, parking, height limits) is in the site's standards. § 90‑386 provides site measurement rules used to judge nonconforming structure changes.
• Typical permitted uses: multifamily dwellings and accessory uses as listed in the development tables (see the code's zone use tables).
• Key nonconforming rules:
  • Involuntary destruction of legal nonconforming multiple‑family housing may be reconstructed up to predamage size, placement and density, subject to limitations (and state Government Code cross‑references for certain multifamily rebuilds). See § 90‑59(2).
  • Rebuilding must comply with applicable edition of the California Building Standards Code (see below) and any more restrictive local standards. § 90‑59(2)(b)(1–2)

C-1, C-2, C‑M (commercial / mixed‑use)

• Purpose / where it applies: neighborhood, general commercial, and commercial‑manufacturing zones; uses are enumerated in the code tables and certain overlays (e.g., Acacia/Sanderson Overlay) list specific permitted uses by zone.
• Typical permitted uses: retail, service, offices; overlay tables (example: C‑2 and C‑M in the Acacia/Sanderson Overlay) show permitted (P), administrative (A) and conditional (C) uses and are part of the zone regulations.
• Key nonconforming rules:
  • A nonconforming nonresidential land use or structure may not be intensified or extended into parts of a property it did not occupy previously. § 90‑58(4–5)
  • A one‑time 25% expansion of a nonconforming nonresidential use is possible only by CUP with findings (protect investment, no adverse effects, parking adequacy, compatibility). § 90‑271
  • When a discretionary entitlement is requested, nonconforming improvements (landscaping, screening, walls, trash enclosures) will be brought into compliance per the code as conditions of approval. § 90‑271(11)

Industrial / M‑zones

• Purpose / where it applies: industrial/commercial manufacturing areas.
• Key nonconforming rules:
  • A nonconforming residential structure located in an industrial district may not be converted to commercial/industrial uses. § 90‑59(7)
  • Reconstruction/repair caps and public safety abatement rules apply as for other structures. § 90‑59(1–6)

How these rules interact with common permitting topics

• Setbacks & development standards: Nonconforming additions must not increase the discrepancy from current setbacks; single‑family exceptions exist (see § 90‑59(8)). Check Hemet Development Standards for the district table used to measure compliance. (Hemet Development Standards).
• Parking: Expansions or changes that would affect required parking are subject to the code’s off‑street parking rules and the CUP findings for nonresidential expansions must demonstrate adequate parking. See Hemet Parking and § 90‑271( a ).
• Design review: Any discretionary approval (e.g., CUP for expansion or Planning Commission hearing for rebuilds over the 50% threshold) will typically trigger design compatibility review under local procedures. See Hemet Design Review; relevant findings are in the CUP and nonconforming sections. Verify with the jurisdiction.
• Overlays and historic districts: Overlay rules can impose additional development requirements or permitted uses that change whether something is nonconforming; see Hemet Overlay Districts and the overlay use tables (example: Acacia/Sanderson).
• ADUs and nonconforming zoning: State ADU law constrains local agencies from denying ADU permits solely because of nonconforming zoning conditions in certain circumstances; the Hemet code does not repeat state ADU limits here—consult Hemet ADUs and state ADU law for interplay. (Not found in retrieved Hemet nonconforming text; verify with jurisdiction.)
• California Building Standards Code / Title 24: Rebuilding of nonconforming multifamily housing must comply with the applicable edition of the California Building Standards Code at the time of reconstruction. See § 90‑59(2)(b)(1) (references the state code). For building‑code specifics consult the California Building Standards Code.

Checklist — what an applicant must have or do if you have a nonconforming condition

• Document the lawful establishment date and basis for the nonconforming right (proof the use/structure was lawful when created). § 90‑56
• Confirm the use has not been discontinued for 180 days (or more, per the specific category) to avoid abandonment. § 90‑58(1)
• If proposing an enlargement of a nonresidential use, prepare a CUP demonstrating the six findings for a 25% one‑time expansion (protects investment, no adverse effects, compatibility, parking intact, architectural compatibility, modernization). § 90‑271
• For reconstruction after damage, obtain a damage estimate; if reconstruction cost will exceed 50% of fair market value, plan for a Planning Commission hearing and the findings required for rebuild. § 90‑59(1)(b)
• Prepare a scope and cost estimate for repairs vs. replacement; cumulative interior nonstructural work is limited to 50% over five years (community development director to determine replacement cost). § 90‑59(3–4)
• If proposing a single‑family addition on a nonconforming SF dwelling, confirm the 25% enlargement limit and any parking or bedroom‑count implications. § 90‑59(8)(a)(2–3)

Risks & Ambiguities

Plain-English Summary

If your lot, use, building, or fence in Hemet pre‑dates current zoning rules, you likely have a legal nonconforming right; you can usually keep it, make limited repairs, and in narrow cases make modest expansions, but long inactivity (about 180 days), major rebuilds over 50% of value, or intensification that increases the mismatch with today’s rules can cause you to lose that right or require discretionary approvals. § 90‑55 through § 90‑59 are the controlling local provisions.
