Last reviewed: July 2, 2026

Overview

This page summarizes the Martinez Municipal Code (Title 22 Zoning) rules that control development standards — setbacks, heights, lot coverage, density and floor-area-ratio — and how they vary by zone or overlay. For a quick view of the city’s zoning map and chapter list see the Martinez zoning overview. This page focuses strictly on the zoning/development-standard rules in the local ordinance (Title 22); building-code requirements (Title 24) and permit procedures are outside this page’s scope. See the city’s guidance on parking, design review, overlay districts, ADUs, variances and exceptions, and the California Building Standards Code where the topic is relevant in the text below.

How to read this page

  • Bolded terms are the actual Martinez district names and numeric standards (e.g., NC, R-1.5, 0.2 FAR).
  • Each numeric requirement is grounded to the Martinez Municipal Code using the controlling § number and the uploaded ordinance text citation.
  • If the ordinance text needed to answer a specific detail was not present in the retrieved files, the page explicitly says "Not found in retrieved materials" so you can verify with the Planning Division.

District-by-district development standards

Downtown Shoreline District

  • Purpose & where it applies: The Downtown Shoreline District encourages mixed downtown uses adjacent to the shoreline and public amenities; design guidance is in the Downtown Specific Plan. See the Downtown provisions for site-specific rules. § 22.23.050 and § 22.23.060 describe the district and its design rules .
  • Typical permitted uses: Mixed residential and commercial forms typical of a downtown environment (see the Downtown Overlay sections). § 22.23.050(D) delegates setbacks/coverage to the Downtown Overlay District (Sections 22.13.040–22.13.090) .
  • Key dimensional standards:
    • Maximum height: 30 ft (typically 2 stories) or 40 ft / 3 stories when built at the higher density of 35 units/acre; Planning Commission may allow other heights by use permit. § 22.23.050(B) .
    • Density: Minimum site area per dwelling unit and potential to approve densities down to 1,250 sq ft/unit (35 units/acre) by use permit. § 22.23.050(C) .
  • Practical note: Many dimensional details are taken from the Downtown Overlay — consult Sections 22.13.040–22.13.090 for block‑by‑block standards. § 22.23.050(D) .

(See the Downtown Overlay on the city site via the city’s overlay page.)

Neighborhood Commercial (NC)

  • Purpose: Small-scale neighborhood commercial uses that serve surrounding residential areas. See general commercial development standards in the zoning chapter. § 22.16.195–22.16.205 address NC district standards .
  • Typical permitted uses: Retail, personal services, small offices; accessory residential where allowed by the district provisions. Not all uses are listed here — consult the permitted uses table in the NC chapter (not reproduced here).
  • Key dimensional standards:
    • Maximum FAR: 1.5 (can increase to 2.0 with the Development Incentives program). § 22.16.195 .
    • Maximum height: 30 ft (can be increased to 40 ft with incentives). § 22.16.200 .
    • Minimum site area per dwelling unit (mixed/residential): 1,500 sq ft/unit. § 22.16.205 .

Service Commercial (SC)

  • Purpose: Auto‑oriented and service commercial uses; larger lot and parking needs than NC. Standards collected with NC/CC rules in the commercial chapter.
  • Key dimensional standards:
    • Maximum FAR: 1.0 (can increase to 1.5 with incentives). § 22.16.195 .
    • Maximum height: 30 ft (increased to 40 ft through incentives). § 22.16.200 .
    • Minimum site area per residential unit (if residential component): 1,500 sq ft/unit. § 22.16.205 .

Central Commercial (CC)

  • Purpose: More intense commercial and mixed-use development in central parts of town.
  • Key dimensional standards:
    • Maximum FAR: 3.0 (can increase to 3.5 with incentives). § 22.16.195 .
    • Maximum height: 40 ft / 3 stories (can increase to 50 ft / 4 stories with incentives). § 22.16.200 .
    • Minimum site area per dwelling unit (if residential): 1,250 sq ft/unit. § 22.16.205 .
  • Transit-area adjustment: Sites within 0.5 mile of Martinez Amtrak Station may have a minimum FAR of 1.0 and max up to 3.5, and specific density ranges are established. § 22.16.195(B) and 22.16.205(B) .

Alhambra Valley (AV/R-20.0, AV/R-40.0, AV/A-5)

  • Where it applies: Rural / Alhambra Valley planning areas; the code keeps special, larger setback and lot rules for agricultural and hillside parcels. See § 22.29.060 for these districts .
  • Key dimensional standards:
    • Maximum FAR: 0.2 in the AV districts. § 22.29.060(E) .
    • Maximum height: 2.5 stories or 35 ft for single‑family structures in Alhambra Valley districts. § 22.29.060(F) .
    • Accessory structure setback relaxations and special animal structure setbacks are explicitly called out in § 22.29.060 (Notes) .

Light and Heavy Industrial districts

  • Key dimensional standards:
    • Maximum FAR: 2.0 (up to 3.0 with development incentives). § 22.18.135 .
    • Maximum height: 50 ft (up to 60 ft with incentives). § 22.18.140 .

Mixed‑Use / Housing Overlay (MUO)

  • Purpose: The MUO encourages multifamily residential in targeted corridors by allowing increased residential densities if affordable housing thresholds are met. § 22.11.010–.040 .
  • Density and standards:
    • If the MUO affordable housing provisions are met, projects must be built at densities between 21.5 and 43 units/acre (and other density rules for opportunity sites). § 22.11.020(A) .
    • Objective development standards state that front/side/rear yard, FAR, coverage, building height, etc., default to the underlying R-1.5 standards unless otherwise specified. § 22.11.040 .
  • Practical note: Because MUO layers on top of the underlying zone, check both the overlay (MUO) and the underlying zoning chapter for applicable numeric standards. See the overlay district page for maps.

Planned Unit Development (PUD)

  • Role: A PUD is an approval path allowing site‑specific standards to replace or supplement base zoning: the PUD plan must set allowable density, FAR, lot coverage, setbacks, height, and parking specifics — and the PUD controls where it differs from Title 22. § 22.42.040–.060; § 22.42.080 .
  • Practical rule: Where a PUD plan is silent, the underlying zoning district standards apply. § 22.42.060(B–C) .

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

  • Governing rules: See the ADU chapter for objective ADU standards: unit size, setbacks, building separation, height measurement, and exemptions. § 22.43.040–.070 cover the main topics .
  • Key ADU numeric rules:
    • Maximum ADU size: 1,200 sq ft (attached or detached) for ADUs (JADU max 500 sq ft). § 22.43.040(B) .
    • Setbacks for ADUs: Front setback same as primary dwelling; side and rear setbacks no less than 4 ft for attached or detached ADUs. § 22.43.050(A–C) .
    • Building separation: Detached ADUs generally require 5 ft separation from other structures unless State‑exempt (then different fire-rating requirements apply). § 22.43.060(A–B) .
    • Lot coverage / FAR: Newly constructed ADUs are exempt from the zoning district’s maximum lot coverage or FAR limits (i.e., ADUs may be allowed above those maxima per the ADU chapter). § 22.43.040(D) .
    • Height for ADUs and how height is measured are covered in § 22.43.070 (height measured from natural grade to topmost point). § 22.43.070 .
  • Practical note: ADU rules in Martinez explicitly track key State ADU provisions (and include ministerial review timelines). See the city ADU page for application steps.

Exceptions and Development Incentives

  • Minor exceptions: The city allows limited minor exceptions to development standards (e.g., small increases in height, small reductions in setbacks) under a defined minor exception procedure and findings. Table 22.45.020(A) lists typical allowable deviations (e.g., up to 5 ft in building height for primary structures, up to 0.1 FAR, 10% coverage, or 10 ft or 25% of a required setback) with the minor exception approval route. § 22.45.020 .
  • Major exceptions / incentives: Larger deviations are possible through the Development Incentives and Community Benefits Program (Chapter 22.81), which ties increased height, reduced setbacks, increased FAR, and parking reductions to provision of community benefits (including affordable housing). § 22.45.020(B) and § 22.81.050 .
  • Practical note: The incentives program is district‑specific — each zoning district has its "incentive" table located in that district chapter. § 22.81.050(A) describes the approach and cross‑references district chapters for the exact numbers .

Minor exceptions summary (selected items)

The city allows limited, administrative "minor exceptions" per Table 22.45.020(A):

  • Building height: up to an additional 5 ft (primary structures) or 2 ft (accessory structures) above limit. § 22.45.020(A) .

  • FAR / Lot coverage: up to 0.1 FAR or 10% lot coverage (or 500 sq ft where noted). § 22.45.020(A) .
  • For larger deviations, the Development Incentives Program (Chapter 22.81) applies — see § 22.81.050. § 22.45.020(B) and § 22.81.050 .

Checklist

  • Confirm zoning designation (e.g., R-1.5, NC, CC, AV/R-20.0) for the parcel with Planning staff. Verify applicable overlays (MUO, Downtown, Historic). Verify with the jurisdiction.
  • Pull the applicable district chapter in Title 22 and note the district-specific numeric standards (height, FAR, lot coverage, site area per dwelling unit). See the zoning chapter list. If MUO or Downtown applies, read both underlying district chapter and overlay chapter. § 22.11.040; § 22.23.050(D) .
  • For proposed residential projects, calculate base density and check for incentives/density‑bonus eligibility (Chapter 22.81, Chapter 22.80). § 22.81.050 .
  • For ADUs, confirm ADU size/setback/separation rules and exemption from FAR/coverage limits in § 22.43.040–.070. § 22.43.040(D) .
  • If your project needs small deviations, evaluate minor exception thresholds in § 22.45.020(A) and prepare findings per § 22.45.040. § 22.45.020–.040 .
  • Check off‑street parking must meet Chapter 22.36 requirements and any reductions available through incentives/overlay. § 22.16.220; Chapter 22.36 Not found in retrieved materials for full table — verify with the City. § 22.16.220 .
  • If using PUD or Development Incentives, secure required community‑benefit commitments and deed restrictions for affordable units per § 22.81.050. § 22.81.050 .

Risks & Ambiguities

Issue Why it matters What to verify
Missing district details for some residential zones (e.g., R‑1.5 numeric yard/coverage tables not fully in retrieved files) Exact setbacks, lot coverage, and minimum lot widths are often in individual district chapters — outcomes depend on those numbers Verify the full district chapter in Title 22 for the parcel; discuss with Planning staff. Not found in retrieved materials.
Applicability of Overlay standards (MUO, Downtown) vs underlying zone Overlays can override or add to base zoning (e.g., Downtown delegates setbacks to the Downtown Overlay) — conflicting standards change design Read both the overlay chapter and underlying district chapter; consult § 22.11.040 and § 22.23.050(D).
ADU exemptions to FAR/coverage ADUs may be exempt from maximum FAR/coverage (important for tight lots) but other constraints (setbacks, separation) still apply Rely on § 22.43.040(D) and related ADU sections; confirm with Building Division on any fire/safety exceptions.
Interaction with State laws (SB 9, ADU law, Density Bonus) State law may mandate ministerial approvals or limit local discretion, changing how zoning standards apply Compare local objective standards (e.g., § 22.51A.050 for SB 9) with State law and consult the City for interpretation. § 22.51A.050
Which height base to use (natural grade vs finished grade) Height measurement assumption changes allowed building height Martinez measures building height from natural grade to topmost point per § 22.43.070 and other district height sections; confirm which measurement the district uses. § 22.43.070

Plain-English Summary

Martinez’s zoning code (Title 22) sets numeric development limits (heights, FAR, lot coverage, setbacks, and density) that differ by district and by specialized overlays; modest variations may be approved as a minor exception, and larger increases are available through the Development Incentives program in Chapter 22.81 if community benefits are provided. Always check both the underlying zone chapter and any overlay (MUO, Downtown) because overlays commonly change setbacks, FAR, or density; confirm parcel‑specific numbers with the Planning Division. See the city ADU chapter for ADU‑specific exceptions (ADUs are often exempt from FAR/coverage limits). § 22.43.040; § 22.45.020; § 22.81.050

Frequently asked questions

What can I build on an R-1 lot in Martinez?

The Martinez code organizes single‑family districts under numeric names like R‑1.5 (and others). The specific permitted uses (single‑family dwellings, accessory structures, ADUs) and numeric setbacks/coverage live in the district chapter for that zone; the retrieved files reference R‑series standards indirectly (for example objective standards for MUO reference R‑1.5) but the full R‑1 numeric tables were not present in the retrieved materials. Verify the parcel’s exact district chapter for the precise list of allowed uses and dimensional standards. Not found in retrieved materials; verify with the Planning Division.

What are Martinez setback requirements?

Setback standards are district‑specific. For ADUs the ordinance sets front = same as primary, side and rear ≥ 4 ft, and allows small architectural projections of up to 18 inches into setbacks. See § 22.43.050 for ADU setbacks and § 22.45.020(A) for allowable minor setback deviations. For other uses, check the underlying district chapter or overlay (e.g., Downtown Overlay). § 22.43.050; § 22.45.020(A); § 22.23.050(D)

What maximum building heights apply in Martinez commercial zones?

Typical maxima in the commercial chapter are: NC/SC = 30 ft (can increase to 40 ft with incentives) and CC = 40 ft / 3 stories (to 50 ft / 4 stories with incentives). Exceptions can be requested via the Development Incentives Program or through the exceptions chapter. See § 22.16.200, § 22.45.020, and § 22.81.050. § 22.16.200; § 22.45.020; § 22.81.050

How does floor‑area‑ratio (FAR) work in Martinez?

FAR maximums are set per district (e.g., NC 1.5, SC 1.0, CC 3.0 with higher FARs available under development incentives). Sites near the Amtrak Station have minimum/maximum FAR rules (transit‑adjacent rules). See § 22.16.195 and the district FAR tables for the exact numbers. § 22.16.195

Do ADUs count toward lot coverage and FAR limits in Martinez?

Newly constructed ADUs are explicitly exempt from the zoning district maximum lot coverage and FAR limits under the ADU chapter; however other ADU standards (setbacks, separation, height) still apply. See § 22.43.040(D). § 22.43.040(D)

Can the city approve a reduced setback or taller building?

Yes — small changes may be approved as a minor exception within the thresholds in Table 22.45.020(A) (e.g., up to 10 ft or 25% of a setback reduction, up to 5 ft height increase for primary structures). Larger deviations are possible through the Development Incentives and Community Benefits Program (Chapter 22.81), subject to findings and community benefit commitments. § 22.45.020; § 22.81.050

If my site is in the MUO overlay, which standards control?

The MUO allows higher residential densities when specific affordability thresholds are met and states that objective development standards default to the underlying district (e.g., R‑1.5) unless the MUO specifies otherwise. Read both § 22.11.020–.040 and the underlying district chapter to determine the controlling numeric standards. § 22.11.020–.040

Are there special rules for hillside or substandard lots?

Yes. For substandard hillside lots with natural slopes above 20%, there is a maximum FAR of 0.30 in the specific hillside chapter, and other averaging rules may apply. See § 22.33.050 for the hillside FAR ceilings and calculation rules. § 22.33.050

Do SB 9 units have different dimensional standards?

Yes — the City’s SB 9 objective standards set specific limits for new SB 9 units on single‑family parcels (e.g., 40 ft front, 4 ft side/rear setbacks for new SB9 units, and a maximum height of 16 ft for new SB9 units). See § 22.51A.050 for the complete objective standard list. § 22.51A.050

When can I use development incentives to increase FAR or height?

If your project provides community benefits (commonly affordable housing) you can apply for development incentives under Chapter 22.81; the incentives program explicitly lists eligible development standard increases (height, FAR, setback reductions, parking reductions). The exact incentive quantities for a parcel are found in each district’s incentive table in its chapter; the Program provides the pathway and findings. § 22.81.050 ---
