Orange — Land Use

Last reviewed: July 2, 2026

Overview

This page summarizes how the City of Orange regulates what may be built and operated on parcels (permitted, accessory, and conditional uses), and where, under Title 17 (Zoning). The Master Land Use Table and the individual zoning chapters control use permissions; numeric development standards for housing are collected in Table 17.14.070 and related sections. See the City’s master use table rules in § 17.13.030 for use-permit categories and the residential chapter for district standards § 17.14.010 . For parking rules, see the Parking chapter § 17.34 (linked inline below) .

First internal links (useful topic pages referenced in text): the City overview is at Orange zoning & planning overview. This page also links inline to Orange Development Standards, Orange Parking, Orange Design Review, Orange Overlay Districts, Orange ADUs, and the California Building Standards Code when those topics arise.

Note on sources: the City’s Master Land Use Table (Table 17.13.030) is maintained as an attachment to Title 17; cross-check specific permitted/conditional uses there for parcel-level decisions § 17.13.030 .

How Orange’s ordinance regulates Land Use (core rules)

• Uses are authorized, limited, or prohibited by the Master Land Use Table in Title 17; the table marks uses as Permitted (P), Conditional (C or CUP), Accessory (A), or Not permitted (-) and points to additional standards where applicable § 17.13.030 .
• Additional/“special” use standards and conditional-use review rules are listed in § 17.13.040 and § 17.13.050 and in use-specific subsections across Title 17 (example: alcohol sales, kennels, amusement arcades) .
• Numeric development standards (front/side/rear setbacks, minimum lot area, height, coverage, usable open space for residential zones) are consolidated in Table 17.14.070 (residential districts) and the mixed-use / industrial chapters contain their own standards; consult the relevant chapter for the base zone § 17.14.010; Table 17.14.070 (residential standards) .
• All projects must also comply with parking (Chapter 17.34) and landscaping/sign standards in other chapters; parking rates are use-specific in Table 17.34.060 and related sections .
• Accessory Dwelling Units (ADUs) and Junior ADUs are separately regulated in Chapter 17.29 and are permitted where the base zone allows single- or multi-family dwellings; see § 17.29.020 and the Master Land Use Table for zone applicability .
• Nonlisted uses may be evaluated by the Community Development Director as substantially similar to listed uses; otherwise the Planning Commission may require a CUP § 17.13.070 .
• Nonconforming uses/developments and rules for repair, expansion, or replacement are governed by Chapter 17.38 (including the special regime for properties made nonconforming by the 2010 General Plan update) § 17.38.065 .

District-by-district breakdown

Below are the City’s zoning districts as listed in Table 17.06.020; each entry gives the stated purpose, typical permitted uses (high-level), key numeric standards where published in the code for that district, and typical locations/where it applies. For specific parcel-level use lists always consult the City’s Master Land Use Table § 17.13.030 .

Note: many specifics (full permitted-use lists) are in the Master Land Use Table attachment; numeric setbacks and minimums for residential zones come from Table 17.14.070 (see the Code Reference column below) .

R1-R (R1-R Single-Family Residential)

• Purpose: preserve single-family neighborhoods and regulate residential quality § 17.14.010 .
• Typical permitted uses: single-family dwellings, accessory uses (garages, ADUs subject to § 17.29.020), home occupations per Master Table § 17.13.030 .
• Key standards (examples from Table 17.14.070): minimum lot area varies by R-1 subtype (see table), front yard typically 20 ft, side yard 5 ft, rear yard 20 ft, max height 32 ft / 2 stories (varies by subzone) — see Table 17.14.070 for each R-1 variant § 17.14.010; Table 17.14.070 .
• Where it applies: mapped single-family neighborhoods; subtypes (R1-5, R1-6, ... R1-40) shown in Table 17.06.020 § 17.06.020 .

R1-5, R1-6, R1-7, R1-8, R1-10, R1-12 (R-1 subtypes)

• Purpose: as above; each subtype has a different minimum lot area per unit and frontage depth in Table 17.14.070. See Table for exact numbers (e.g., R1-6 = 6,000 sf min lot area, R1-8 = 8,000 sf, etc.) Table 17.14.070 .

R2-6, R2-7, R2-8 (Duplex Residential)

• Purpose: allow duplex or two-unit development with standards in Chapter 17.14 and Table 17.14.070 § 17.14.010; Table 17.14.070 .
• Typical uses: duplexes, accessory units (per Chapter 17.29) § 17.29.020 .

R-3, R-4 (Multi-family Residential)

• Purpose: provide for higher-density multi-family housing; numeric standards and architecture/design review references found in Chapter 17.14 and multi-family objective design standards § 17.14.010; § 17.19.235 .
• Density/intensity: subject to General Plan maximum FAR and tabled standards; see Table 17.14.070 and multi-family standards Table 17.14.070; § 17.19.235 .

MH (Mobile Home Residential)

• Purpose/uses: mobile home parks and associated accessory uses, regulated under Chapter 17.14 and the Master Land Use Table § 17.14.010; § 17.13.030 .

OP (Office Professional), CP (Commercial Professional), C1, C-TR, C2, C3 (Commercial)

• Purpose: office/professional services and retail/service commercial uses; use permissions and whether alcohol or restaurants are allowed depend on the Master Land Use Table and special sections (alcohol regulated in Chapter 17.30) § 17.13.030; § 17.30.040 .
• Key controls: parking per Chapter 17.34, sign rules in Chapter 17.36, and special conditional-use rules for alcohol, large restaurants, etc. § 17.34; § 17.36 .

OTMU-15S, OTMU-15, OTMU-24 (Old Towne Mixed Use) and NMU-24, UMU (Mixed-Use / Urban)

• Purpose: support pedestrian-oriented retail/office on ground floor with residential allowed above or as freestanding in appropriate locations; Old Towne districts have distinct historic-design standards § 17.19.075; § 17.19.230 .
• Typical uses: ground-floor commercial retail/professional; residential as mixed-use or stand-alone; density and FAR ranges appear in the mixed-use chapter (for example UMU density: 30–60 DU/AC; intensity: 1.5–3.0 FAR — see the UMU description in the mixed-use chapter) § 17.19.060; § 17.19.075 .
• Design review/site plan: many UMU and Old Towne projects require site plan and design review; see Orange Design Review and § 17.19.060 .

• Planned Unit Developments must be approved by CUP and adopted by ordinance; see § 17.16.020—§ 17.16.040 for PUD procedures and findings .

Overlay Districts (FP — floodplain, A — Single-Story overlay, E — Equestrian, P — Parking overlay, NP — Neighborhood Preservation, etc.)

• Purpose: overlays impose additional development or use controls layered over base zones (see Table 17.06.020 listing overlays and Chapter 17.28 for overlay provisions) § 17.06.020; Chapter 17.28 .
• Old Towne overlay/Historic: Old Towne standards require conformance with Historic Preservation Design Standards (see § 17.19.230 and the Historic Preservation chapter) and Orange Historic Preservation is relevant here .

Quick reference table — selected decision-relevant items

Practical guidance / interpretation tips

• Use permission: Start at the Master Land Use Table (Table 17.13.030) to see whether a use is P, C, A, or not allowed; the Table also points to special standards in Title 17 (alcohol, kennels, arcade rules, etc.) § 17.13.030—§ 17.13.050 .
• Numeric standards: For single- and multi-family projects consult Table 17.14.070 for lot area, setbacks, height, lot coverage, and usable open space; for mixed-use consult Chapter 17.19 and Old Towne standards where applicable § 17.14.010; Table 17.14.070; § 17.19.075 .
• Parking and loading: Always check Chapter 17.34 (including Downtown Plaza special rules) as parking requirements frequently drive project feasibility; see Orange Parking and Table 17.34.060 .
• Design review: Many nonresidential, mixed-use, and Old Towne projects require site plan and/or design review; consult § 17.19.060 and the design review chapter early in design Orange Design Review .
• ADUs: ADUs are permitted only where the base zoning allows a primary dwelling; Chapter 17.29 sets ADU rules (height/size/placements) and you must also check state ADU law for preemption issues California ADU law § 17.29.020 .
• Overlays & historic districts: If your parcel falls inside overlays (Floodplain, Neighborhood Preservation, Old Towne etc.) additional standards apply — consult Chapter 17.28 and Old Towne design standards § 17.19.230 and Orange Overlay Districts .
• Nonlisted uses: The Community Development Director can determine similarity to listed uses or refer the matter to the Planning Commission for a CUP § 17.13.070 .

Checklist (what an applicant must satisfy)

• Confirm base zoning for the parcel (match against Table 17.06.020) § 17.06.020
• Consult the Master Land Use Table (Table 17.13.030) to determine P/C/A status and any special standards § 17.13.030
• If a residential project: verify dimensional standards in Table 17.14.070 (lot area, setbacks, height, coverage, usable open space) Table 17.14.070
• Calculate parking and loading demand per Chapter 17.34 / Table 17.34.060 § 17.34.060
• Check overlay districts and Old Towne/historic design standards where mapped § 17.19.230; Chapter 17.28
• Determine if ADU rules apply and follow Chapter 17.29 for ADU/JADU submittal § 17.29.020
• Determine whether project requires Site Plan/Design Review or a Conditional Use Permit (CUP) and prepare findings per the applicable sections § 17.10.060; § 17.13.050 (See Design Review chapter)
• Review sign and landscaping standards (Chapters 17.36 and municipal landscape requirements/Chapter 16.50) § 17.36.010; § 17.14.210
• Verify compliance with state codes where they apply (e.g., California Building Standards Code).

Risks & Ambiguities

Plain-English summary

Orange’s zoning (Title 17) regulates which uses are allowed where by a central Master Land Use Table; residential numeric standards live in Table 17.14.070, mixed-use and industrial chapters add their own standards, and overlays (Old Towne, floodplain, Neighborhood Preservation, etc.) add extra rules — consult the Master Table § 17.13.030, the residential table Table 17.14.070, and overlay chapters for parcel-specific answers § 17.13.030; Table 17.14.070 .
