Hemet — Development Standards

Last reviewed: July 3, 2026

Overview

This page summarizes development standards in the City of Hemet zoning/planning ordinance (municipal code) as they control setbacks, heights, lot coverage, density and floor‑area ratios (FAR). It interprets the city’s base-zone dimensional tables, site development rules, and special‑zone provisions so applicants can quickly find the numeric limits and the code sections to verify. Where the code text in the City file set is silent or ambiguous, I note that explicitly and suggest verification with the jurisdiction.

For the city’s overall zoning context see the Hemet zoning & planning overview and the Hemet Zoning pages. For related details you will see links to Hemet Parking, Hemet Design Review, Hemet Overlay Districts, Hemet ADUs and the California Building Standards Code where the municipal code refers to those topics.

How this page is grounded

Every numeric standard and procedural point below cites the controlling municipal code section (bold § references). The underlying Hemet zoning excerpts used here are from the uploaded Hemet municipal code materials (file excerpts) .

District-by-district development standards

Notes about terminology used below: the municipal code places dimensional tables and site development rules in several articles; the table numbers and yard measurement rules appear in the cited sections. For how yards are measured, see § 90-386 . For site development review and design findings see § 90-48 and related site review provisions .

R-R (Rural Residential)

• Purpose: The R-R zone provides for large residential lots that combine rural and urban living and may allow limited agricultural activity. § 90-313 .
• Typical permitted uses: Large-lot single‑family homes and agricultural uses (detailed permitted‑use lists not found in the retrieved excerpts; verify with the code). Verify with § 90-313 .
• Key dimensional standards: Minimum lot area: 1 acre; front setback: 20 ft; rear setback: 10 ft; side setback: 10 ft; max building height: 40 ft (all from § 90-185 table for A‑zones which applies to agricultural/residential lots in some contexts — confirm applicability to specific R-R parcels) .
• Where it applies: As mapped on Hemet’s official zoning map; see § 90-313 .

R-1 (Single-family residential — subdistricts R-1-5, R-1-6, R-1-7.2, R-1-10, R-1-20, R-1-40)

• Purpose: The R-1 zone is for single‑family homes at a range of lot sizes. § 90-313 .
• Typical permitted uses: Detached single‑family dwellings and customary accessory structures (specific use schedules not included in the retrieved excerpts; verify). See § 90-313 .
• Key dimensional standards: Minimum lot sizes are differentiated by subzone: R-1-5 = 5,000 sf, R-1-6 = 6,000 sf, R-1-7.2 = 7,200 sf, R-1-10 = 10,000 sf, R-1-20 = 20,000 sf, R-1-40 = 40,000 sf (table in § 90-313). New single‑family projects are subject to pre‑application and site development review per § 90-314 .
• Height / coverage / setbacks: The R‑1-specific numeric front/side/rear setbacks, maximum lot coverage and height references are contained in the single‑family development tables and site requirements (see § 90-314 and measurement rules in § 90-386) .

R-2, R-3, R-4 (Multiple-family residential)

• Purpose: R-2, R-3, R-4 provide for increasing multifamily densities and building heights; the code gives separate tables and site rules for multifamily development. § 90-385 / § 90-386 .
• Typical permitted uses: Multifamily dwellings, supportive residential projects and senior housing (subject to the multifamily standards). Detailed use lists not included in the retrieved excerpts; verify with the code. See § 90-385 .
• Key dimensional standards (summary of the municipal table): Density (max units/gross acre): R‑2 = 8, R‑3 = 30, R‑4 = 45; Net lot area: R‑2 = 6,000 sf, R‑3 = 1 acre, R‑4 = 2 acres; Lot width: R‑2 = 60 ft, R‑3 = 100 ft, R‑4 = 100 ft; Height (habitable): R‑2 = 30 ft (2 stories), R‑3 = 45 ft (3 stories), R‑4 = 55 ft (4 stories) — all in § 90-385 and the development tables in § 90-386 .
• Additional rules: buffering to single‑family requires 20 ft landscaping plus the five feet per story buffer in § 90-385(k)(2); lighting and landscaping rules are in § 90-386(k) and related subsections .

A‑ZONES (A‑1, A‑2, A‑2‑10 — Agricultural)

• Purpose: The A‑zones conserve agricultural land and control urbanization (see § 90-185). § 90-185 .
• Key dimensional standards: Minimum lot area: A‑1 = 1 acre, A‑2 = 5 acres, A‑2‑10 = 10 acres; front setback: 20 ft, rear: 10 ft, side: 10 ft; building height: 40 ft; lot coverage: none (all in § 90-185 table) .

Commercial zones — O‑P, C‑1, C‑2, C‑M

• Purpose: Provide for office, retail/consumer services, and commercial manufacturing/warehousing (the development tables are in the commercial article). § 90-313 and the commercial tables in § 90-895 / the development standard table apply .
• Key dimensional standards: Max lot coverage: O‑P = 60%, C‑1/C‑2/C‑M = 40%; Front landscaped setback: O‑P = 20 ft, C‑1/C‑2/C‑M = 10 ft; Height limits: O‑P = 40 ft, C‑1 = 35 ft, C‑2 = 35 ft, C‑M = 55 ft (commercial standards table in § 90-313 and § 90-895) .
• Commercial design requirements and colors, accessory structures, landscaping and signage are tied to the commercial design standards in § 90-895 and the sign article (Article XXXVI) .

Manufacturing / Business Park — BP, M‑1, M‑2

• Purpose: Industrial and business park uses; development standards are in the manufacturing article. See § 90-1045 onward for manufacturing zone minimum development standards .
• Key dimensional standards (from the table): Lot coverage: BP 65% / M‑1 60% / M‑2 60%; FAR (max): BP = 0.60 / M‑1 = 0.45 / M‑2 = 0.45; Net lot area: BP = 20,000 sf / M‑1 & M‑2 = 10,000 sf; Front yard setback: BP 20 ft / M‑1 15 ft / M‑2 15 ft; Side & rear setbacks vary and increase where adjacent to residential (30 ft); Heights: BP = 55 ft / M‑1 = 60 ft / M‑2 = 60 ft (see § 90-1045 and referenced subsections such as § 90-1046(c) and § 90-1046(g)(1)) .

TR‑20 (Independent Mobile Home Subdivision)

• Purpose and permitted uses: Zone allows subdivisions of not less than 20 acres for independent mobile homes and related accessory structures; one independent mobile home per lot (see § 90-681 — § 90-682) .
• Dimensional standards: Travel/trailer PD specific development rules (heights, lot coverage and access drives) are found in the TRPD article; e.g., building height for TTPD = 15 ft, recreation buildings up to 35 ft in § 90-815; consult § 90-681—§ 90-818 for full requirements .

Public Institutional (PI)

• Site, setbacks and height: PI has no minimum site area or lot width/depth, setbacks and placement are determined as part of project review, and maximum building height is 35 ft unless otherwise authorized (see § 90-1216—§ 90-1219) .

Planned Community Development (PCD) and Specific Plan (SP)

• PCD: Development standards are set by the approved community master plan; building coverage limit 50% for PCDs is noted in § 90-623 and density “shall conform to the approved community master plan” .
• SP: A Specific Plan (SP) replaces the base zone where adopted; if the SP is silent on a standard, the Hemet Municipal Code applies (see § 90-980—§ 90-982) . Always verify the specific plan document for controlling dimensional standards.

Accessory Dwelling Units (ADUs) and Junior ADUs (JADUs)

• Hemet’s local ADU provisions allow detached ADUs with a one‑story height cap of 16 ft, increased to 18 ft in some transit/proximity conditions, and a two‑story detached ADU over a garage may reach 25 ft with side/rear setbacks per § 90-315; attached ADUs may be built to the primary dwelling height up to 25 ft / two stories depending on the base zone (see § 90-315 for the full ADU rules and state‑law alignment details) .
• ADU development standards must comply with base zone objective standards unless they would physically preclude an 800 sf ADU with 4‑ft side/rear setbacks (the municipal ADU provisions incorporate the state ADU constraints) — see § 90-315 and the ADU excerpts in the retrieved materials .

Quick standards table (decision‑relevant excerpts)

(Where the municipal excerpts reference other articles — e.g., parking in Article XL or signage in Article XXXVI — check those articles for details; the development tables frequently point back to those articles and to site development rules such as § 90-386.)

Checklist — what an applicant must satisfy (high‑level)

• Meet the base‑zone dimensional table for the parcel (setbacks, lot coverage, height, density or minimum lot area) per the zone table (see § 90-313, § 90-385, § 90-1045 as applicable) .
• Complete site development review / design review and demonstrate the design findings in § 90-48 and related site review sections (see Hemet Design Review and the site requirements) .
• Provide required parking per the municipal parking rules (see Article XL and zone cross‑references) and show compliance on plans (see Hemet Parking) .
• Demonstrate compliance with landscape, screening and buffering rules (multifamily buffer rules, commercial landscape frontage rules) as in § 90-385(k) and § 90-895(h) (see Hemet Landscaping and Screening) .
• For projects in a Specific Plan, follow the specific plan standards where adopted; if the SP is silent, apply the municipal code standard (§ 90-982) .
• For ADUs, follow § 90-315 and state ADU law; confirm the ADU height and setback exceptions and minimum‑size allowance (see Hemet ADUs and California ADU law) .
• Ensure building permits reference the California Building Standards Code (Title 24) and the city’s building permit requirements (see Hemet Zoning and California Building Standards Code) .

Risks & Ambiguities

Plain‑English summary

Hemet’s zoning tables set the numeric yardsticks: single‑family subzones (R‑1 variants) specify minimum lot sizes and basic setbacks; multifamily zones (R‑2, R‑3, R‑4) set explicit densities, lot widths and heights; commercial and manufacturing zones specify lot coverage, FAR and larger height allowances. ADUs are regulated under a dedicated local ADU rule that aligns with state ADU law and allows at least an 800‑sf ADU with 4‑ft side/rear setbacks in many cases. Always check whether a parcel sits inside a Specific Plan, PCD, or the Hemet‑Ryan Airport Influence Area because those override or add constraints. Key code entry points: § 90-313, § 90-314, § 90-385, § 90-386, § 90-895, § 90-1045 and § 90-315.

Information Gaps

• Full, parcel‑specific permitted‑use lists for many zones were not present in the retrieved excerpts. Verify the permitted uses in the full municipal code for the affected zone. (Not found in retrieved materials.)
• Some residential subzone lot‑coverage or FAR values were not visible in the extracted snippets for R‑1 subtypes — confirm in the full zoning tables. (Not found in retrieved materials.)
• Article XL (parking) and Article XXXVI (signage) are referenced repeatedly but their detailed tables were not included among retrieved excerpts; check those articles for precise parking counts and sign rules. (Not found in retrieved materials.)
