Yucaipa Zoning, Planning & Building Codes

Last reviewed: June 30, 2026

Overview

Yucaipa regulates land use through its Development Code (Title 8 of the City Code), not a “Title 17 Zoning” as in some cities. The code is organized so that districts, procedures, and “citywide” rules are easy to find once you know the numbering: 81.xx for general provisions, 83.xx for permits and maps, 84.xx for districts, and 87–88.xx for development and design standards. At a glance, districts run from rural to industrial, with a dedicated high‑density multifamily district and a Planned Development tool; overlays (e.g., floodplain; hillside) and specific plans add site‑specific layers. State housing mandates (ADUs/JADUs, SB 9, and related programs) are implemented locally and dovetail with Yucaipa’s administrative and zoning review tracks.

How Yucaipa’s code is organized

• Official name and where to start. The ordinance is the “Development Code of the City of Yucaipa,” with general authority and consistency rules in Chapter 81.01 (e.g., “Citation,” “Authority,” and General Plan consistency) and the Official Land Use Plan is adopted at §81.0145 . The glossary confirms the Development Code is Title 8 of the City Code (§812.04055) .
• How it’s laid out.
  • Division 1 (81.xx): general provisions and how the code prevails where stricter than other rules (§81.0120–§81.0135) .
  • Division 3 (83.xx): approvals and maps, including Planned Development procedures (§83.030205–§83.030225), Planning Use Permits (§83.030405–§83.030410), revocations (§83.030323), and subdivision procedures (§83.040105–§83.040110) .
  • Division 4 (84.xx): Land Use Districts—this is where each zoning district’s use list and numeric standards live; the full list is established at §84.0301 .
  • Division 7 (87.xx): “citywide” development standards like height (§87.0401), signage (§87.0701), design review applicability (§87.1205–§87.1210), and landscaping (§87.1305–§87.1310) .
  • Division 8 (88.xx): design standards by housing type, including multifamily (RM) and the RM‑24 high‑density standards (§88.0201; §88.01301 et seq.) .
• Where to find the map and permits. The Official Land Use Plan is adopted at §81.0145; basic building/land‑disturbance permits are “Development Permits” defined at §812.04070; subdivisions follow §83.040105–§83.040110 (staff vs. Planning Commission review) .

Zoning district families

Yucaipa’s districts are established by symbol at §84.0301: RL, RS, RM, RM‑24, CN, CG, CS, IC, P, IN, FW, PD, OS . Key, city‑specific highlights:

Residential

• RL — Rural Living. Low‑intensity residential and animal‑raising on large lots. Typical standards: 1 du/ac max density, 1.0 ac minimum lot, 30 ft front, 15 ft side, 25 ft rear, 35 ft height, 40% max lot/building coverage (§84.0320(c)) .
• RS — Single Residential. Neighborhood single‑family. Standards: 4.2 du/ac max density, 7,200 sf minimum lot, 25 ft front, 10 ft & 5 ft sides, 20 ft rear, 35 ft height, 55% lot coverage and 40% building coverage (§84.0325(c)) .
• RM — Multiple Residential. Up to small multifamily by right, larger by CUP: “Ten or fewer multiple‑dwelling units” via Land Use Compliance Review; “more than 10” via CUP (§84.0330(a)(6), (b)(1)). Property standards mirror RS for single‑family and add RM specifics; 35 ft height; 7,200 sf minimum lot; 60% coverage cap (§84.0330(c)) .
• RM‑24 — High Density Multiple Residential. Purpose‑built high density housing with “by‑right” multifamily per administrative review (§84.0335(2) referencing §83.030305), 20–24 du/ac required density range, 2 ac minimum lot, 45 ft height base (with a mixed‑use height increase of up to 20%), and deeper front setbacks for multi‑story (e.g., 35–40 ft avg.) (§84.0335(b)) . Detailed RM‑24 development standards and parking appear in Division 8, Chapter 13 (§88.01301; §88.01305) .

Commercial and Industrial

• CN — Neighborhood Commercial. Neighborhood‑serving uses; 0.5 FAR, 35 ft height, 1 ac minimum lot, 25 ft front; tailored side/rear rules near non‑commercial neighbors (§84.0340(c)) .
• CG — General Commercial. Broader retail/services; 1.0 FAR, 45 ft height, 1 ac minimum lot, 15 ft front (§84.0350(d)) .
• CS — Service Commercial. Auto‑oriented/contractor services; 1.2 FAR, 45 ft height, 1 ac minimum lot, 15 ft front (§84.0355(d)) .
• IC — Community Industrial. Light/medium industrial; 1.0 FAR, 45 ft height, 1 ac minimum lot, 15 ft front (§84.0370(c)) .

Civic and Open Space

• P — Park. Public parks/recreation with 45 ft height, 15 ft front, 10 ft side/rear (§84.0360(c)) .
• IN — Institutional. Civic/education/health; 0.8 FAR, 75 ft height, 15/10/10 ft front/side/rear (§84.0380(c)) .
• OS — Open Space. Resource/open space; typically 35 ft height and 1 ac minimum lots where used as a base designation (§84.0395(c)) .

Special Purpose

• FW — Floodway. Development constraints with plan‑based flood rise protection and cross‑compliance with the Floodplain Overlay (§84.0385(c), referencing §85.020325) .
• PD — Planned Development. A district and process to vary standards for superior design; findings and procedures at §83.030205–§83.030225, with PD district allowances and even animal‑raising parameters in §84.0390 .

Citywide development standards

• Height, measurement, and lot math. Yucaipa centralizes core rules: height increases and triggers (e.g., projects ≥3 stories or with conditioned space above 30 ft or any building above 45 ft are subject to an aerial ladder truck funding resolution) in §87.0401–§87.0405; RM density calculations and lot‑area math in §87.0320–§87.0340 .
• Parking. For typical dwellings, Yucaipa requires 2 on‑site spaces per unit, placed behind the front setback (tandem generally prohibited except in mountain areas). Mobilehome parks and small‑lot/single‑family condo projects have tailored ratios, and qualifying housing developments can use alternative ratios under §83.010715/§83.010730 (cross‑referenced in the parking section) . Multifamily development standards add more detail: RM projects need dedicated on‑site and guest parking (§88.0205), and RM‑24 has its own covered/garage mix, guest ratios, and spacing rules (§88.01305) .
• Design and landscaping. Citywide design review applies to all land use districts (§87.1205–§87.1210), and projects must also meet landscaping and screening rules like drought‑tolerant planting, compost incorporation, and tree counts (§87.1305–§87.1310) . RM and RM‑24 add detailed site/building guidelines in Division 8 (e.g., RM‑24 §§88.01345–88.01350) .
• Signs. Citywide signage rules start at §87.0701, with district‑specific sign matrices embedded in each district chapter (e.g., CG/CS/IC/IN) .

Specific plans & overlays

• Specific plans. The high‑density RM‑24 program expressly applies “including within the Freeway Corridor Specific Plan,” with consolidated review and customized standards residing in Division 8, Chapter 13 (§84.0335(1); §88.01301) .
• Overlays and special areas. Yucaipa uses overlay districts to address constrained areas. Floodway parcels must also meet Floodplain Overlay requirements (§84.0385(c) referencing §85.020325) . Separate hillside/ridgeline procedures require a Hillside Plan Review with Community Development Director/DRC evaluation prior to grading or construction in designated hillside/ridgeline areas (application/permit process noted under “Hillside Plan Review”) .
• Historic resources. A historic preservation program may exist outside the retrieved chapters. Not found in retrieved materials—verify with the City Clerk or Planning.

Building permits & review

• Start with the map and district rules. The Official Land Use Plan is adopted at §81.0145, and the applicable district’s use table and numeric standards control (§84.03xx) .
• Administrative/discretionary paths.
  • Land Use Compliance Review and “by‑right” allowances apply in several places (e.g., up to 10 RM units at §84.0330(a)(6); RM‑24 multifamily by administrative review per §84.0335(2), referencing §83.030305) .
  • Conditional Use Permits are triggered for larger/more intensive uses (e.g., RM projects with “more than 10” units; many commercial/industrial use classes) (§84.0330(b)(1); CN/CG/CS subsections) .
  • Planned Development can flex standards when findings are made (§83.030205–§83.030225; §84.0390) .
  • Planning Use Permit offers a streamlined CUP alternative for small, CEQA‑exempt proposals meeting set criteria (§83.030405–§83.030410) .
• Subdivision and mapping. Tentative tract/vesting maps with more than 10 lots require a public hearing before the Planning Commission; smaller maps may be approved administratively by the Community Development Director (§83.040110). Design and improvement standards for maps appear at §83.041120 .
• Permits and building code. A “Development Permit” includes building and grading permits (§812.04070). Building work must follow the California Building Standards Code (Title 24) as locally amended; Yucaipa’s Citywide Design Guidelines also apply (§87.1210) .

State housing law in Yucaipa

• ADUs/JADUs. Yucaipa implements state ADU law by offering a “building‑permit‑only” path for ADUs/JADUs that meet the California ADU law baseline; such ADUs/JADUs are rented for terms of 31+ days, cannot be sold separately (with narrow state exceptions), and JADUs need no additional parking (§[local ADU chapter—building‑permit‑only path] and JADU standards) . State minimums—like allowing at least an 800 sf ADU with 4‑ft side/rear setbacks and defined height limits—apply citywide under California housing laws and the statewide ADU guidance .
• SB 9 urban lot splits. The code provides an urban lot split track “pursuant to the regulations starting with Section 88.01701,” enabling qualifying two‑lot splits of single‑family parcels consistent with SB 9 (§ reference noted in historic preservation section) .
• Density/parking reductions. The code cross‑references special parking ratios for qualifying housing developments (§83.010715, §83.010730), which function alongside state density/parking relief programs; consult the project’s eligibility and the cited sections in Yucaipa’s parking rules .
