Pittsburg — Design Review

Design Review under the Pittsburg local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

The City of Pittsburg administers design review to shape the appearance and site integration of projects across its zoning map; the rules live in Chapter 18.36 of the Pittsburg Municipal Code and apply to all land use districts, with specific procedures for single‑family projects and different (often commission‑level) review for larger or nonresidential projects (§ 18.36.020) . The ordinance prescribes required submittals, the review standards planners and the planning commission use (mass, materials, setbacks, landscaping, etc.), and where design review is mandatory (for example, every project in PD, GQ, CP, -P and -O districts) (§§ 18.36.210, 18.36.220, 18.62.080, 18.72.100, 18.74.080) .

Note: the phrase “design review” below links to the City's zoning/permit menu for convenience; other relevant topic pages are linked where they first appear in text.

Article‑by‑article synthesis of the Pittsburg rules and how they apply in each local district follows. Where the ordinance sets district‑level expectations that trigger or condition design review, that district appears as its own subsection.

How the ordinance organizes review (short version)

Chapter 18.36 is the Design Review chapter (general purpose, single‑family rules, non‑single‑family rules, standards, submittals, hearings, appeals) — see § 18.36.010–§ 18.36.400 .
Single‑family building permits that add above‑ground area or materially alter grade are reviewed administratively by the city planner under § 18.36.100; if the planner has doubt, the planning commission takes the application (§ 18.36.100) .
Non‑single‑family projects (and most land‑use permits) are reviewed by the planning commission under § 18.36.200; the city has downtown design guidelines that may prevail for the downtown commercial core (§ 18.36.200) .
Required submittals (site plan, architectural drawings, landscaping, photos, color/material samples, and more) are listed in § 18.36.210; standards planners/commission must consider are in § 18.36.220 .

District-by-district breakdown (where design review is referenced)

Note: the code uses several district abbreviations; each district name below is written exactly as in the code and bolded. All statements below are grounded in the cited Pittsburg Municipal Code sections.

Single‑family land use districts (general "R" / single‑family districts)

Purpose: maintain consistent neighborhood design and prevent substandard development; design review is intended to be the minimum necessary control (§ 18.36.100) .
Who reviews: the city planner reviews building permits for above‑ground work or material grading changes; planner approval allows building permit issuance, planner denial prevents issuance; if uncertain, application is referred to the planning commission (§ 18.36.100) .
Typical permitted uses: single‑family dwellings and accessory uses as specified in the applicable R district (detailed use lists live in the district chapters referenced by the zoning code) — review applicability comes from § 18.36.100 .
Key design expectations: the planning commission prescribes criteria by resolution (these criteria are used by the planner) (§ 18.36.120) .
Where it applies: any single‑family zoning district in the city where construction is above ground or materially alters grade (§ 18.36.100) .

Planned Development (PD) district

Purpose & typical uses: PD is intended for large, flexible developments where unified design is important; design review is integral to PD plan approval (§ 18.62.010) .
Review trigger: the PD chapter states that each project within a PD requires design review under Chapter 18.36, and the city will not accept plans for design review unless consistent with an approved PD plan or specific plan (§ 18.62.080) .
Key standards to expect in practice: PD plans and conditions may supersede or supplement base district rules (setbacks, height, circulation, landscaping) and the PD approval/plan typically governs the design review findings (§ 18.62.010, § 18.62.080) .

Commercial‑Professional / Old Town – CP district

Purpose & typical uses: commercial and office uses appropriate to the CP base district; Old Town Pittsburg-specific design guidance is referenced (Old Town Design Guidelines) (§ references in nonconforming chapter and CP rules) .
Review trigger: CP and Old Town contexts frequently require plan review and design review; projects that do not conform to Old Town guidelines must supply a schedule to eliminate nonconformities and obtain design review approval (§ 18.76.070) .
Key standards to expect: conformance to Old Town Pittsburg Design Guidelines and any CP-specific development regulations; the design review process is used to integrate improvements with historic patterns and adjacent development (§ 18.36.220; § 18.76.070) .

Governmental and Quasipublic (GQ) district

Purpose & typical uses: public, institutional, educational, or recreational sites of two acres or more; development regulations are often set through use permits or design review (§ 18.60.010–.040) .
Review trigger: all projects in GQ require design review under Chapter 18.36 (§ 18.60.050) .
Practical note: large institutional projects should expect planning commission review and conditions aimed at preserving neighborhood balance and public facility function (§ 18.60.010–.050) .

Limited Overlay (-O), Master Plan (-P), and other overlays

Purpose & typical uses: overlays are used to preserve special site features, allow flexibility, or implement master plans; by code, design review is required for projects in these overlays (§ 18.74.010; § 18.74.080; § 18.72.100) .
Trigger: plans for projects in -O or -P overlay districts are not accepted for design review unless consistent with an adopted overlay/master plan; the ordinances require design review for each project in those overlay districts (§ 18.74.080; § 18.72.100) .
Where it applies: applied on a site‑specific basis via zoning map designators (e.g., adding “‑O” or “‑P” to a parcel) — check the city zoning map to see overlay extents (verify with planning staff) (§ 18.74.020; § 18.72.070) .

Temporarily Unclassified (S) and Rural / Other base districts

The code explicitly requires design review for projects in the S district and many rural or special base districts; for example, rural residential rules reference design review and that development must meet design review where required (§ 18.64.050; § 18.58.040) .
Substandard lots in any R district must obtain design review approval (see § 18.84.655) .

Most decision‑relevant standards & submittals (quick reference)

Topic / Decision factor	What the code requires or focuses on	Code reference
Purpose / scope of review	Design review applies citywide to projects in all land use districts; single‑family gets planner review; non‑single‑family goes to planning commission (§ 18.36.020–.200)	§ 18.36.020; § 18.36.100; § 18.36.200
Required application materials (non‑single family)	Site plan, architectural drawings (elevations, floor plans), landscaping plan, photos, color/material samples, parking layout, drainage, utilities, etc. (§ 18.36.210)	§ 18.36.210

(For full development standards — e.g., exact setbacks, lot coverage, FAR — consult the district chapters and the Pittsburg Development Standards.)

Checklist — what an applicant must provide (minimum, per the code)

Completed application form to the city planner (form and filing rules per the planner) — filing required by the city planner (§ 18.36.210, § 18.36.200)
Site plan showing property boundaries, existing/proposed structures and heights, parking (quantity and dimensions), access, utilities, drainage, existing trees, retaining walls and distances to property lines (§ 18.36.210(A)(1–19))
Architectural drawings — floor plans and four elevations at required scales (§ 18.36.210(B))
Landscaping plan with plant species, sizes, and irrigation plan (§ 18.36.210(C))
Color and material samples, photographs of existing site and adjacent properties, and any additional data requested by the planner or commission (§ 18.36.210(D–F))
If in a PD, -O, or -P district: evidence of consistency with the approved PD/overlay/master plan (§ 18.62.080; § 18.74.080; § 18.72.100)
Check parking and setback calculations against the applicable district standards and provide a statement of conformance (parking linked requirements in § 18.36.210(A)(7))

For parking details see the city's parking rules at the Pittsburg Parking page; for exact setback and dimensional numbers see the Pittsburg Development Standards.

Risks & Ambiguities

Issue	Why it matters	What to verify
Applicability to ADUs (Accessory Dwelling Units)	Some cities exempt ministerial ADU permits from discretionary design review; Pittsburg's design review chapter does not explicitly say ADUs are exempt. Relying on a mistaken exemption can delay permits.	Not found in retrieved materials — verify with the Planning Department whether ADUs require design review or are processed ministerially; also see Pittsburg ADUs and California ADU law for state constraints.
Downtown commercial core guidelines vs code	Downtown design guidelines may override code provisions for that core area (§ 18.36.200). If you assume the zoning code controls, you could miss mandatory guideline conformity.	Verify whether your property lies in the downtown commercial core and obtain the city‑adopted downtown design guidelines (§ 18.36.200) .
Consistency with approved PD / -O / -P plans	The code will not accept plans for design review if they are inconsistent with an approved plan (§ 18.62.080; § 18.74.080; § 18.72.100). A design that differs could be rejected at intake.	Confirm whether an approved PD/overlay/master plan applies to the parcel and obtain the controlling plan paperwork before submitting (§ 18.62.080; § 18.74.080; § 18.72.100) .
Timing and permit sequencing (zoning vs building)	Design review approvals expire after one year without building/grading permits (§ 18.36.240). Failure to coordinate can cause re‑submittal.	Verify approval expiration dates and schedule building permit intake to avoid lapsing (§ 18.36.240) .
Standards that are adopted by resolution (single‑family review criteria)	The planner applies criteria the planning commission adopts by resolution for single‑family review (§ 18.36.120). Those criteria may not be in the zoning code text.	Request copies of the planning commission resolutions and any city‑adopted design guidelines that apply to your neighborhood (§ 18.36.120) .

Plain-English Summary

Pittsburg’s design review rules (Chapter 18.36) mean most projects — from single‑family additions to large commercial or PD developments — must submit site plans, elevations, landscaping, and material/color samples; small single‑family work is reviewed by the city planner while larger/non‑residential projects go to the planning commission, and overlays or PD plans can add or override requirements. The review looks at height, bulk, materials, parking, landscaping and how well the design fits the neighborhood; approvals typically expire after one year if a building or grading permit isn’t pulled (§§ 18.36.100–.240, 18.36.210–.220) .

Frequently asked questions

Do I need design review for a small addition to my single‑family house in Pittsburg?

Small single‑family additions that are above ground or materially alter existing grade are subject to design review by the city planner; the planner will approve the permit if the project meets the locally adopted criteria, or will refer it to the planning commission if there is doubt (§ 18.36.100) .

What submittals are required for design review of a commercial project?

Non‑single‑family projects must include a site plan (showing structures, parking, utilities, grading, trees, etc.), architectural drawings (floor plans and elevations), a landscaping/irrigation plan, photos, and color/material samples as specified in § 18.36.210; additional materials may be requested by the planner or commission (§ 18.36.210) .

Does the downtown commercial core have special design rules?

Yes — the code requires city council‑adopted design guidelines for the downtown commercial core and states those guidelines shall be applied by reviewers and may prevail over conflicting code sections in that area (§ 18.36.200) .

If my parcel is in a PD or overlay district, can I submit a plan that differs from the approved PD/master/overlay plan?

No — the city will not accept plans for design review in a PD, -O or -P district unless they are consistent with the approved PD plan, overlay plan or master plan; check §§ 18.62.080, 18.74.080 and 18.72.100 for the exact rule language .

How long does design review approval last?

A design review approval terminates upon its terms or upon the expiration of one year from approval unless a building or grading permit has been issued; the planning commission may extend the approval if requested in writing within the effective period (§ 18.36.240) .

Will parking and setback compliance be checked during design review?

Yes — applicants must show parking locations and whether they conform to applicable regulations on design review submittals, and reviewers will consider maximum height, lot coverage and setbacks among other factors (§ 18.36.210(A)(7); § 18.36.220(A)(1)) . For the parking standards themselves see the city’s parking chapter and development standards at the Pittsburg Parking and Pittsburg Development Standards pages.

Are historic or contributing buildings reviewed differently?

Yes — for designated historic buildings or properties in historic districts, reviewers must use the general design review standards and the city’s adopted design criteria/design guidelines for historic properties; the reviewer must find the work will not adversely affect character‑defining exterior features (see § 18.36.220(C)) .

What happens if the city planner denies a single‑family design review?

If the city planner denies approval for a single‑family project, the authority that denied the application must provide written findings to the applicant within 10 calendar days (§ 18.36.300) .

Are substandard lots treated differently?

Yes — design review approval is required for substandard lots, and Chapter 18.84 contains development standards and procedures that apply to substandard lots in R or nonresidential districts (see § 18.84.655) .

Who sets the design review criteria used for administrative reviews of single‑family projects?

The planning commission prescribes the review criteria by resolution; these adopted criteria are applied by the city planner in single‑family reviews (§ 18.36.120) . ---
