Chino Zoning, Planning & Building Codes

Last reviewed: July 1, 2026

Overview

This page orients you to the City of Chino’s local zoning and planning framework as codified in the Chino Municipal Code (Title 20—Zoning). The code organizes base zoning districts (residential, commercial, industrial, mixed‑use, agriculture/open space/public), a set of overlay districts, and citywide development rules (setbacks, height, FAR, lot coverage, parking) plus special‑area specific plans and administrative procedures for permits, zone changes and site approvals. For quick navigation to topic pages, see Chino’s pages on parking, development standards, design review, overlay districts, ADUs, and the California Building Standards Code (links inline below).

How Chino's code is organized

• The Zoning Code is implemented as chapters of the Chino Municipal Code and structures regulation by topic: zoning districts and their tables (residential, mixed‑use, commercial, industrial, agricultural/open space/public), overlay districts, citywide standards, use‑specific rules, and administrative procedures (applications, specific plans, zone changes, site approval). The rule that citywide standards supplement the district rules is stated in § 20.10.010.
• Administrative procedures for specific plans, zone changes and other amendments are in the Chapter 20.23 series; adoption/amendment of specific plans is governed by § 20.23.050 and zone change procedures by § 20.23.060.
• The code uses numeric section headings (for example § 20.04.040, § 20.05.040, § 20.06.040, § 20.07.040, § 20.08.040) to present the development‑standards tables for each district family; consult those sections for the district‑by‑district minimums and maximums.

(NOTE: the city’s zoning tables are collected in the municipal chapters referenced above; use the table headers in each section to find numeric setbacks, FAR, lot coverage and parking cross‑references.)

Zoning district families

Chino groups districts into standard families; the local names and representative development rules are in the cited code sections below.

• Single‑ and multifamily residential: RD 1, RD 2, RD 4.5, RD 8, RD 12, and higher residential districts. Standards (minimum lot area, front/rear/interior side setbacks, lot coverage, FAR, heights) are summarized in § 20.04.040; for example RD 1 shows a 1‑acre minimum lot and 25 ft front setback and .20 FAR in the table in § 20.04.040.
• Mixed‑use districts: MU 20 and MU 30 (maximum densities 20 and 30 DU/acre respectively, FAR 1.0 and 1.5, and maximum heights 45 ft and 55 ft). See the mixed‑use development standards in § 20.05.040.
• Commercial districts: several commercial categories (for example CN, CG, CO, CR, CS) with different lot‑area, setback, FAR and height profiles; see § 20.06.040 for the commercial table (e.g., CG permits up to 120 ft building height in the table).
• Industrial districts: BP, M1, M2, and the AD (Airport Development) district; industrial setback rules, lot coverage, FAR and special buffering to residential are in § 20.07.040.
• Agriculture / Open Space / Public: AG, OS‑1, OS‑2, P, PS; development standards for these districts appear in § 20.08.040 (large minimum lot sizes, substantial front setbacks, etc.).
• Overlay districts: Chino applies overlays to add rules on top of the base zones — for example the Affordable Housing Overlay (AHO), Agricultural Overlay (AO), Airport Overlay (A), Downtown Overlay (DO), and Mixed Use Overlay (MUO). The purpose and applicability of overlays is described in § 20.09.010 and § 20.09.020 (and overlay conflict rules in § 20.09.030).

Citywide development standards

Chino’s code layers citywide standards (performance, landscaping, parking cross‑references, use‑specific standards) on top of district tables.

• The general purpose for citywide standards is set out in § 20.10.010, and the performance standards (noise, emissions, storage, nuisance rules) are in § 20.10.020. These are the baseline rules that every use must satisfy in addition to district rules.
• Setbacks, lot coverage, FAR and height: the district tables give the numeric caps and minimums. Examples: RD tables show front setbacks of 25 ft (varies by RD zone) and maximum building height 35 ft for typical single‑family districts in § 20.04.040; the MU tables show maximum lot coverage 80%, FAR 1.0/1.5, and heights 45/55 ft in § 20.05.040; commercial and industrial numeric limits are in § 20.06.040 and § 20.07.040 respectively.
• Parking: off‑street parking and loading standards are handled in the parking chapter and are cross‑referenced from each district table (see the repeated “See Chapter 20.18 (Parking)” notes in § 20.04.040, § 20.05.040 and § 20.06.040). Consult the city’s parking rules for vehicle counts, dimensions, and design standards. See the city’s guidance on parking.
  • (First mention) More on parking is at Chino’s Parking page. (/us/california/chino/parking)
• Landscaping, screening, refuse and recycling, and pedestrian/streetscape expectations are found in the citywide chapters and in the design standard sections referenced by the overlay and district tables (e.g., landscape minimums are flagged in the district tables and Chapter 20.19 is cited for landscape coverage requirements). See § 20.09.7 notes and the landscape cross‑references in the tables.

Design standards, discretionary review and objective review

• Chino separates numeric/measurable standards in the district tables from design and objective standards that guide appearance and site layout. Multiple‑family and mixed‑use design standards are collected in the code and referenced directly from the overlay/district tables (for example Section 20.17.050 for multiple‑family design standards, Section 20.17.060 for mixed‑use, and Section 20.17.070 for commercial design). These sections are used when planning staff and commissions evaluate projects.
• The city uses a site approval and design review approach for larger residential and mixed‑use projects: residential/mixed‑use projects in the AHO or MUO require site approval and design review is conducted to determine compliance with the city’s objective design standards under the site approval process (see § 20.09.090 and the cross‑reference to § 20.23.090 for site approval).
  • (First mention) For procedural steps and how design findings are applied, see Chino’s Design Review page. (/us/california/chino/design-review)

Specific plans & overlays (key area plans)

• Specific plans are adopted under Government Code authority and the Chino code’s procedures in § 20.23.050; area‑specific standards (for example the Central Avenue Specific Plan and downtown/civic center provisions) supplement the zoning rules inside the plan boundaries and may set different minimum lot widths and allowed uses in those areas. See the Central Avenue specific plan references in the municipal code text.
• Overlay districts (for example AHO, AO, A (airport), DO, MUO) add or override standards of the base zone where applied; overlay purpose, applicability and conflict rules are in § 20.09.010–§ 20.09.030. The Airport Overlay contains use compatibility tables and requires avigation easements in certain overflight zones per § 20.09.050.

(First mention) The city’s overlay district summaries are on the Overlay Districts page. (/us/california/chino/overlay-districts)

Building permits & review: the typical path

• Ministerial permits (building permits) and discretionary land‑use approvals are separate steps: the zoning code establishes use permissibility, development standards, and the discretionary review processes (conditional use permits, site approval, variances, zone changes) while building permits are issued through the building department under the state code. The code establishes application, notice and hearing rules (see Chapter 20.23 procedures such as § 20.23.030 for applications/fees references and § 20.23.140 for public notices and hearings where applicable).
• Typical permit ladder: (1) confirm base zoning and applicable overlay/specific plan (district tables in § 20.04.040, § 20.05.040, etc.), (2) determine whether the proposed use is permitted or requires a conditional use permit or site approval (see chapters and use tables), (3) submit discretionary applications (conditional use permit, site approval, design review) when required (procedures in Chapter 20.23), (4) obtain environmental clearance, (5) apply for building permits and inspections under the state code. The Planning Commission and City Council have explicit roles in zone changes and specific plan adoption per § 20.23.060 and § 20.23.050.

State housing law in Chino — ADUs, density bonus, SB9, and rent rules

Summary of how state housing law intersects with Chino’s code (what the local code shows and where state law fills gaps):

• Accessory dwelling units (ADUs) / JADUs: The retrieved Chino zoning excerpts do not contain a dedicated local ADU ordinance text in the materials provided here (search of the retrieved municipal code excerpts did not show an ADU chapter). Therefore state ADU law governs where the local code is silent; statewide ADU rules (permit ministerial limits, size, setbacks and parking constraints) are summarized in the California ADU law guidance. For details on state ADU standards, see California ADU law and the California ADU handbook. (/us/california/california-adu-laws)
  • (First mention) Chino’s ADU information page is here. (/us/california/chino/adu)
• Density bonuses and affordable housing overlays: Chino’s Affordable Housing Overlay (AHO) and the mixed‑use overlay provide explicit mechanisms to increase density and FAR for projects that include affordable units; the AHO development standards and the procedure for additional density are described in the AHO and MUO provisions (see the AHO table and accompanying notes which allow additional FAR where qualifying affordable rental units are provided and the preliminary review/site approval process for added density in § 20.09.090). This is Chino’s local pathway for incentivizing affordable units in exchange for density/standard concessions.
• SB 9 (ministerial lot splits / duplexes) and other recent state statutes: those state laws may preempt or constrain local review (ministerial lot splits, objective design standards, etc.). The Chino Municipal Code excerpts we reviewed do not show an explicit SB 9 implementation provision; where the local code is silent, state law controls. Verify specific SB 9 implementation questions with the city’s planning staff. (Not found in retrieved materials.)
• Local rent control: no rent‑control / rent stabilization ordinance language was found in the zoning excerpts provided. Confirm with Chino’s municipal code or city clerk for any separate rental‑housing ordinances. (Not found in retrieved materials.)

Practical orientation / quick tips

• To find numeric standards for a parcel, start with the base zone table: residential rules are in § 20.04.040, mixed‑use in § 20.05.040, commercial in § 20.06.040, industrial in § 20.07.040, and agriculture/open/public in § 20.08.040.
• If an overlay applies (AHO, MUO, Airport overlay, etc.), overlay rules can override base‑zone standards; see § 20.09.010–§ 20.09.030 for purpose, applicability and conflict rules and the AHO/MUO tables for design and density incentives.
• Large residential or mixed‑use projects that rely on increased density or affordable housing incentives will typically need preliminary review and then site approval per the site approval procedure in § 20.23.090 and the AHO/MUO provisions in § 20.09.090.

Information gaps / things to verify with City of Chino

• Local ADU (ministerial) ordinance language: not present in the retrieved zoning excerpts; confirm whether Chino has an adopted ADU section or uses state law only. (Not found in retrieved materials.)
• Any post‑2024 local amendments or stand‑alone housing ordinances (e.g., SB 9 implementation or local rent rules) were not included in the provided files—check the city’s current municipal code online or contact Planning. (Not found in retrieved materials.)
• For exact parking counts, dimensional standards and accessible parking requirements, consult Chapter 20.18 (Parking) — the district tables repeatedly cross‑reference that chapter but the parking chapter text itself was not supplied in full here.
