Pittsburg — Land Use

Last reviewed: July 2, 2026

Overview

This page summarizes how the City of Pittsburg’s zoning ordinance (Title 18 PMC) governs what may be built or used on a parcel and where different uses are allowed. It is focused only on land‑use rules (permitted vs. conditional uses, district rules, overlay constraints and the controlling development tables), not building standards, tenant law, or permitting process details. The ordinance locates land‑use rules in the base district chapters (Division III), overlay chapters (Division IV) and the use/permit rules (Division V); design review and development standards are cross‑referenced throughout. See the City’s rules on design review for the citywide design process. § 18.06.

Division/naming note: the code uses specific Pittsburg district designations such as RR, RS‑40, RS‑10, RS‑6, RS‑5, RS‑4, RM, RMD, RH, RHD (residential); CC, CP, CO (commercial varieties); IP, IL, IG (industrial); GQ (government/quasi‑public); PD (planned development); temporary S and interim study overlay __‑S. Land‑use classifications and the long land‑use table entries (the “L‑numbers”) specify permitted vs. conditional status for specific activities. § 18.06.080 and Division III headers.

District-by-district breakdown

Note: where the ordinance points to a district development table or specific plan for numeric dimensional controls, that cross‑reference is cited. If a numeric standard (setback, FAR, lot coverage) does not appear in the retrieved excerpts, the text below flags "Not found in retrieved materials" and points you to the table or chapter that controls.

Residential districts — RR, RS‑40, RS‑10, RS‑6, RS‑5, RS‑4, RM, RMD, RH, RHD

• Purpose: The city groups single‑ and multifamily districts under Chapter 18.50 (Residential Districts) to implement the general plan's residential policies. § 18.50.005
• Typical permitted uses: owner‑occupied and rental housing types appropriate to each district (single‑family in RS classes; multifamily in RM, RMD, RH, RHD). Accessory uses are allowed consistent with the definitions (e.g., accessory dwelling units — see the local ADU rules and state law). The code organizes the specific allowed/conditional uses through the land‑use table (the L‑classifications). § 18.50.010; Land use table (L‑entries)
• Key development controls: projects require design review or specific development standards as set out in § 18.50.100 and § 18.50.105; those sections point to the property development regulations (tables) for each R district. Numeric setbacks, lot coverage and heights are set in the property development regulations table(s). § 18.50.100, § 18.50.105 — Numeric values: Not found in retrieved materials (see the property development tables referenced in those sections).
• Where it applies: residentially‑zoned parcels across Pittsburg per the zoning map; multifamily projects have additional multifamily‑project standards in § 18.50.125. § 18.50.125

(When you need the exact numeric setbacks, consult the property development tables in Chapter 18.50 or contact the City — those numeric tables are the controlling source. Verify with the jurisdiction.)

Commercial districts — CC, CP, CO, and related

• Purpose: Commercial districts regulate neighborhood/commercial centers, pedestrian‑oriented cores and office/commercial uses. See Chapter 18.60 (commercial/property development for CC and related districts). § 18.60.040
• Typical permitted uses: retail, restaurants, offices, and mixed‑use (residential over commercial in certain locations). Many specific commercial uses are allowed or conditioned via the L‑use table entries (examples: outdoor dining requires an outdoor dining permit; some entertainment or large‑floor‑area uses require a conditional use permit). See the land‑use table L‑items for specific limits (for example, ground‑floor restrictions next to Railroad Avenue). § 18.60.040; L‑entries
• Key development controls: the code defaults nonresidential and mixed‑use development in specific corridors to the CC district property development regulations and mandates design review for all projects. § 18.53.030; § 18.60.050
• Where it applies: downtown/pedestrian corridors, West 10th Street Mixed‑Use Corridor, Railroad Avenue Specific Plan and BART master plan areas have special rules that modify CC controls; see the specific plan chapters. § 18.53.030

Note on pedestrian commercial: if a project is in the CP district the planning findings require supporting pedestrian‑oriented downtown goals. § 18.16.050(J)

Industrial districts — IP, IL, IG

• Purpose: Industrial districts are addressed in Chapter 18.54 and are intended for different levels of industrial activity (light to general industrial). § 18.54.
• Typical permitted uses: manufacturing, warehousing, research and ancillary office/service functions — status (permitted vs. conditional) is set by the land‑use tables and specific L‑entries (for example, outdoor storage rules, setbacks from nonindustrial districts, and restrictions on activities that occur outside buildings). See L‑entries in the land‑use table for use‑specific limits. § 18.54.115; L‑entries
• Key development controls: projects require design review (Chapter 18.36) and the development regulations are set in Table 18.54.115 (IP, IL and IG districts – development regulations). Several L‑entries require buffers (e.g., outdoor manufacturing or mining outside buildings must be 200 feet from rights‑of‑way or non‑industrial districts). § 18.54.100; § 18.54.115
• Where it applies: industrially zoned parcels per the zoning map; certain uses restricted to portions of the Railroad Avenue specific plan or east of Harbor Street are indicated by L‑notes. For location‑limited permissions see relevant L‑entries. L‑entries

Government / Quasi‑Public — GQ

• Purpose: To accommodate public, institutional and quasi‑public uses. Reference appears in several L‑entries and in district summaries. (GQ references in L‑entries)
• Typical permitted uses: public facilities, government offices, and in some circumstances residential processed under the "most appropriate" zoning as determined by the city planner or planning commission for redevelopment. L‑entries include special findings that must be made for commercial uses in GQ. L‑entries (e.g., L‑158)
• Key development controls: project‑specific; the planning commission or city planner must make findings regarding adjacency, transit proximity or street access for some commercial uses. Numeric standards: Not found in retrieved materials (consult the GQ chapter/property development table). L‑entries

Planned Development — PD

• Purpose: A flexible district administered through a PD plan or specific plan to allow unique site designs and mixed uses. § 18.62.030
• Typical permitted uses: No new use is allowed in a PD except as authorized by an approved PD plan or specific plan; uses allowed elsewhere in the code may be included in a PD if the PD plan expressly allows them and is consistent with the general plan. § 18.62.030
• Key development controls: PDs must submit a PD plan with maps, site plans, densities, FAR, architectural guidelines and landscape plans; minimum PD area is generally four acres unless a special finding is made. § 18.62.040; § 18.62.050

Temporarily unclassified district — S

• Purpose: The S district is an interim classification for annexed or otherwise temporarily unzoned lands. § 18.64.010–.020
• Typical permitted uses: No use other than an existing use or an accessory use is permitted in an S district; expansion or new uses require a use permit. § 18.64.030(A–C)
• Key development controls: temporary uses follow single‑family residential district provisions; other development is governed by use permits. § 18.64.030–.040

Overlay districts (e.g., interim study __‑S and others)

• Purpose: Overlay districts add site‑ or area‑specific rules to a base district. The Interim Study Overlay (__‑S) is used to allow discretionary review where zoning is under study. Chapter 18.70
• Key rules: Use permits are required for new or expanded uses in an __‑S, and approval must find consistency with policies adopted when the overlay was enacted; any project in an overlay must conform to an adopted overlay plan. § 18.70.030; § 18.74.080

Quick decision table (most decision‑relevant items)

Practical guidance (plain‑English synthesis)

• Always start at the land‑use table (the ordinance’s L‑entries) for the specific activity you have in mind; that table determines whether an activity is permitted, conditionally permitted (use permit required), or prohibited in a named district. The L‑entries contain many location‑specific qualifiers (e.g., Railroad Avenue, proximity to schools, floor‑area thresholds). (Land‑use table: L‑entries)
• If your parcel is in a PD or a specific plan area (Railroad Avenue or BART master plan), the specific plan/PD plan controls — these can supersede base‑district defaults. § 18.62.030; § 18.53.030
• Most projects require design review and will need to meet the applicable property development regulations; check the development tables in Chapter 18 (e.g., Table 18.54.115 for industrial). § 18.36.
• Parking requirements are separate and cross‑referenced; confirm parking counts and location in the Pittsburg Parking rules and the property development regulations. § 18.32.010 (zoning approval cross‑reference to building/permits)

Checklist — what an applicant must satisfy (first pass)

• Confirm base zoning district on the Pittsburg zoning map and the district designation (e.g., RMD, CC, IP). § 18.06.065
• Check the land‑use table (L‑entries) for the exact use classification and note any L‑notes or distance/area limits. (Land‑use table L‑entries)
• Determine whether the use is Permitted, Conditionally Permitted (use permit required) or Prohibited; note special conditions (hours, drop‑off space, buffers). (L‑entries)
• Identify applicable property development regulations (Chapter 18.50 for R, 18.54 for I, 18.60 for CC/CO) and pull numeric setbacks, heights, FAR or lot coverage from the table for that district. § 18.50.105; § 18.54.115; § 18.60.040
• Prepare design review submittal per Pittsburg Design Review. § 18.36.200 et seq.
• Confirm parking requirements with the Pittsburg Parking standards and any site‑specific parking notes in the L‑entries. § 18.32.010
• If in an overlay or specific plan area, collect the overlay plan or specific plan and reconcile its rules with base zoning. See Pittsburg Overlay Districts. § 18.74.060
• If proposing an ADU, consult the local ADU rules and state ADU law; local code cross‑references accessory dwelling definitions. See Pittsburg ADUs and California ADU law. § 18.06.090 (definition cross‑refs).

Risks & Ambiguities

Plain-English Summary

The Pittsburg zoning ordinance (Title 18 PMC) decides allowable uses by district: check the land‑use table first to see if your activity is permitted, needs a use permit, or is prohibited; then check the district’s property development regulations and any specific plan or overlay that applies. Design review is broadly required and many commercial/industrial activities have site‑specific L‑notes that add buffers or size limits. (Land‑use table; Chs. 18.36, 18.50, 18.54, 18.60)
