Manteca — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes the City of Manteca's zoning development standards — the rules that set setbacks, maximum heights, allowed density, and related controls for each base zoning district in Title 17 (the Zoning Code). The authoritative table is Table 17.26.020-1 (Development Standards for Manteca’s Base Zoning Districts) and the supporting rules for multifamily projects, small‑lot development, accessory dwelling units (ADUs), height measurement, and overlays are in the cited sections below. See the City-wide zoning menu for related topics such as parking, design review, overlay districts, and ADUs. The underlying ordinance text is Title 17 — referenced in each subsection below (§17.26.020, etc.) .

Chapter and key sections used here:

• Title 17 — Zoning Code, Chapter 17.26 (Development Standards by Zoning District) — § 17.26.010 – § 17.26.050 and Table 17.26.020-1 (the master district standards) .
• Multifamily add-ons: § 17.26.030 (open space / private open space) .
• Small-lot single-family standards: § 17.26.040 and Table 17.26.020-2 (small-lot standards) .
• ADUs: Chapter 17.82 (Accessory Dwelling Units) — development standards and exemptions (setbacks, height, lot coverage) .
• Height measurement & exceptions: § 17.42.030 and § 17.42.040 .
• Accessory structures and their setbacks/height: Chapter 17.40 and Table 17.40.040-1 .
• Overlay rules (e.g., Central Business District / DMU overlay and Planned Development overlay): § 17.30.020 and § 17.30.030 .
• Minor Zone Modification (waivers up to 10–20% for yards/height/lot coverage): § 17.10.100 .

District-by-district breakdown

Note: the principal numeric summary for all districts is presented in Table 17.26.020-1; each district entry below highlights the ordinance purpose/typical uses where the code text provides them and calls out the most-decision-relevant dimensional standards that the ordinance lists. Where the exact numeric value for a standard was not visible in the retrieved excerpts, the entry points you to the controlling Table/section and flags the gap.

AG — Agricultural Zoning District

• Purpose / typical uses: agricultural uses, farm buildings, accessory residences in agricultural settings (see Title 17 uses listings). See base district list in § 17.26.020 .
• Key dimensional standards from the table: Minimum density 0 du/ac, Maximum density 2.0 du/ac, Front setback 50 ft, Side setback 15 ft, Rear setback 20 ft (Table 17.26.020-1) .
• Where it applies: geographically mapped as AG on the city zoning map. Verify parcel-specific overlay rules (e.g., Floodplain) before design — see overlay districts and § 17.30.030 .

R-E — Residential Estate Zoning District

• Purpose / typical uses: large-lot single-family and estate residential (see § 17.26.020 district list) .
• Key dimensional standards: Minimum density 0.5 du/ac, Maximum density 2.0 du/ac. Front/side/rear yard minimums are listed in Table 17.26.020-1 — confirm on the table for a specific site .

R-1 — One‑Family Dwelling Zoning District

• Purpose / typical uses: conventional single-family neighborhoods; primary permitted use is single-family detached housing (see district list) .
• Key dimensional standards (from Table 17.26.020-1): Minimum density ~2.1 du/ac, Maximum density 8.0 du/ac, Front setback 20 ft, Side setback 5 ft, Street side yard 10 ft, Rear yard 15 ft. For infill small-lot single-family projects there is a separate small-lot standard with Front 15 ft, Side 5 ft/0 ft (one side zero), Rear 10 ft, Height 30 ft — see § 17.26.040 and Table 17.26.020-2 for small‑lot rules .
• Notes: ADUs in R-1 follow Chapter 17.82; ADUs are exempt from lot coverage counting and have their own 4‑ft side/rear setback rules and a 16‑ft height cap for detached ADUs unless state ADU law provides otherwise (§ 17.82.030) .

R-2 — Limited Multi‑Family Dwelling

• Purpose / typical uses: duplexes, small multifamily buildings; additional multifamily standards apply (§ 17.26.030) .
• Key dimensional standards (Table 17.26.020-1): Minimum density ~8.1 du/ac, Maximum density 15.0 du/ac, Front setback 15 ft, Side setback 5 ft, Street side yard 10 ft, Rear yard 10 ft; multi‑family projects also require 30% project open space and 400 sq ft private open space per unit per § 17.26.030 .

R-3 — Multiple‑Family Dwelling

• Purpose / typical uses: medium‑to‑higher-density apartment housing; subject to the multi‑family standards in § 17.26.030 .
• Key standards: Minimum density ~15.1 du/ac, Maximum density 25.0 du/ac; Table 17.26.020-1 provides setbacks and height for R-3 — see § 17.26.020 for the exact table entries (rear/side stepbacks for buildings above second story also noted) .

CMU — Mixed‑Use Commercial Zoning District

• Purpose / typical uses: pedestrian-oriented mixed residential + retail/commercial. The ordinance explicitly identifies active non‑residential uses (retail, restaurants, medical, civic, lodging, etc.) as appropriate in CMU .
• Key dimensional standards: densities are higher (Table shows min ~20.1 du/ac, max 30.0 du/ac), setbacks smaller than residential districts (see Table 17.26.020-1). Mixed‑use properties that combine residential and non‑residential development have an increased FAR up to 1.75 in some cases (note in the table) .
• Design/permitting tips: parking reductions and incentives may apply for mixed‑use projects — coordinate with the City and the parking standards and with design review for façades and active uses .

DMU — Mixed‑Use Downtown / Central Business District Overlay (CBD)

• Purpose / typical uses: downtown, pedestrian-first, active storefronts. The CBD overlay sets special downtown standards in Table 17.30.020-2 (zero setbacks, higher intensity) .
• Key overlay numeric standards: Front/side/rear/setbacks 0 ft (build to the property line where appropriate), Maximum building height 3 stories / 45 ft, Maximum FAR 1.0 in the CBD overlay (Table 17.30.020-2) .
• Note: The CBD overlay also instructs that new construction shall not locate required parking between the building and the street — see Chapter 17.30 and Chapter 17.52 (Parking) .

BIP — Business Industrial Park

• Purpose / typical uses: office/industrial park uses; setbacks and height are applied to provide buffers to residential areas. Table 17.26.020-1 shows no minimum interior side/rear setbacks in some configurations and special street-side setbacks (example: 25 ft in some cases) — always check the district column in Table 17.26.020-1 and the footnotes .

CN / CG / CM — Commercial Districts

• Purpose / typical uses: neighborhood retail (CN), general commercial (CG), commercial manufacturing (CM). Setbacks are typically 0 ft in commercial zones for frontage and side yards in many contexts (see Table 17.26.020-1); confirm parking & loading in Chapter 17.52 and sign rules in Chapter 17.10 .

M‑1 / M‑2 — Light and Heavy Industrial

• Purpose / typical uses: manufacturing and heavy industrial operations. Table 17.26.020-1 lists no minimum setbacks for many yard types in M‑zones and other industrial‑appropriate controls — check the table and the performance standards in Chapter 17.58 for nuisances (noise, odors, etc.) .

OS / A / PQP — Open Space, Park, Public/Quasi‑Public

• Purpose / typical uses: parks, recreation, public facilities. Development standards differ and are listed in Table 17.26.020-1; specific park improvements follow other City standards. See § 17.26.020 and the Table for precise setbacks & lot requirements .

Quick reference table (most decision‑relevant standards)

• Table source: Table 17.26.020-1 and the small‑lot Table 17.26.020-2 for sub‑6,000 sf lots; see § 17.26.020, § 17.26.040 .
• Where a district column or a numeric cell wasn’t visible in the retrieved excerpts for every yard/coverage value, see the full Table 17.26.020-1 in the ordinance for parcel‑specific values — verify with the City for precise measurements on a given lot .

Important cross‑rules and definitions applicants must know

• Height is measured from natural grade to the plane at the allowed feet (height measurement rule) — § 17.42.030 .
• Certain features are explicitly exempt from height limits (e.g., elevator penthouses, church spires) — § 17.42.040 .
• Accessory structures have their own setbacks, maximum rear‑yard coverage, and height limits in Chapter 17.40 and Table 17.40.040‑1 (e.g., small accessory buildings ≤120 sf have different rules) .
• ADUs: Chapter 17.82 controls ADU setbacks, lot coverage treatment, count, and height. Key points: ADUs are exempt from lot coverage calculations of the underlying zoning (with exceptions for attached garages, porches counting), ADU side/rear setbacks are 4 ft, and detached ADU height is 16 ft in the city ordinance (subject to State ADU law adjustments) — see § 17.82.030 and state law references; also see the City ADU page for practical intake steps .
• Multifamily projects must provide 30% project open space and 400 sq ft private open space per unit in addition to the Table standards — § 17.26.030 .
• Overlays and Planned Developments may supersede Table 17.26.020-1; a Planned Development adopted by ordinance contains its own development standards that prevail where in conflict — § 17.30.030 .
• The City permits minor deviations via Minor Zone Modification: up to 10% waiver for yards/lot coverage/height (20% for additions) — § 17.10.100 .

Checklist (what an applicant must satisfy before building)

• Confirm the parcel’s base zoning (e.g., R-1, CMU, DMU) and any overlay or Planned Development that applies (check zoning map and § 17.26.020) .
• Pull the specific line for the parcel in Table 17.26.020-1 and Table 17.26.020-2 (if small‑lot) and document front/side/street-side/rear setbacks, maximum height, and density limits (§ 17.26.020, § 17.26.040) .
• Check ADU rules if proposing an accessory unit (Chapter 17.82); confirm lot coverage treatment and the 4‑ft side/rear ADU setback rule .
• Confirm parking demand per Chapter 17.52 and whether parking reductions/incentives apply for mixed‑use projects; coordinate with the parking standards .
• For downtown projects, apply the DMU/CBD overlay build‑to and FAR rules (Table 17.30.020-2) and contact planning for parking exceptions and design guidance .
• Measure building height per § 17.42.030 and note any allowed height exceptions in § 17.42.040 .
• If seeking deviations, assess Minor Zone Modification or Variance routes and standards (see § 17.10.100 and the Variances chapter); link to variances and exceptions for process steps .
• Check design review triggers and coordinate with design review early — façade, setback, and active‑use requirements can require discretionary review .
• Verify consistency with applicable site planning standards (landscaping/screening, signs, fences) — see landscaping and screening and signage pages.

Risks & Ambiguities

Plain-English Summary

Manteca’s development standards are organized in Table 17.26.020-1 (Title 17), which prescribes per‑district setbacks, height, and density (e.g., R‑1 typically has 20 ft front, 5 ft side, 15 ft rear; DMU/CBD overlay allows 0 ft setbacks and 3 stories/45 ft), with special rules for multifamily open space, small‑lot developments, and ADUs; always check overlays and the full table for your parcel before designing (§ 17.26.020, § 17.26.030, § 17.26.040, § 17.82.030) .
