Santa Maria — Zoning

Q: Where are mixed-use and live-work rules found and do they affect parking?

Mixed-use and Live-Work/Work-Live rules are in Chapter 12-49 (for example § 12-49.06 covers live-work units). Mixed-use projects follow Chapter 12-32 parking rules but the code allows administrative and Planning Commission reductions (10% / up to 25%) under stated conditions (§ 12-49.*; Chapter 12-32 referenced) .

Overview

Santa Maria's zoning is set out in the Municipal Code (commonly referred to in local practice as the zoning title). The City establishes named base districts (for example R-1, C-1, M-1, OS, etc.), overlay districts (for example H, PD, AA) and a single official Zoning Map that assigns each parcel to a district. The list of districts and the map are adopted by ordinance (§ 12-3.01; § 12-3.02) .

Note: this page summarizes what the Santa Maria zoning ordinance text (as retrieved) says about zoning districts and how they function. For parcel-specific rules, always verify with the Community Development Department. Verify with the jurisdiction.

How to read this page, links and scope

This page covers only zoning (districts, overlays, permitted/conditional uses, and the standards the ordinance points you to). It does not cover building-code compliance (see the California Building Standards Code), separate permitting procedures, or tenant/housing law. Where the zoning code refers to other technical subjects you will see links to the City's related guidance: Santa Maria Development Standards, Santa Maria Parking, Santa Maria Design Review, Santa Maria Overlay Districts, and Santa Maria ADUs. Use those pages for the work the ordinance punts to elsewhere (for example parking rates in Chapter 12-32) .

District-by-district (what the ordinance actually says)

The City enumerates the base and combining districts in the zoning title (§ 12-3.01) — the following subsections synthesize what the Municipal Code text provides for each district name that appears on the official map. For each district: purpose (as stated or implied by the code), typical permitted uses (where the code states them), key dimensional standards only when the ordinance text retrieved explicitly supplies them, and where the district appears to apply. If a specific numeric standard or section is not shown in the retrieved materials, that fact is stated.

All district names below are listed in the ordinance (§ 12-3.01) .

OS (Open Space)

Purpose: The OS district is intended to preserve natural resources, provide outdoor recreation and protect public health and safety; preserve scenic areas and provide areas for future planned growth (§ 12-4.02) .
Typical permitted uses: Not reproduced in the retrieved snippet; see § 12-4.* in the Municipal Code for permitted/conditional uses (Not found in retrieved materials).
Key dimensional standards: Not found in retrieved materials.
Where it applies: Any undeclared / undesignated land defaults to OS per the ordinance (§ 12-3.03) .

RA (Residential Agricultural)

Purpose: Land area for low-density residential/agricultural type uses (district name appears in § 12-3.01) .
Typical permitted uses: Not found in retrieved materials (verify with the code chapter for RA).
Key dimensional standards: Not found in retrieved materials.
Where it applies: As shown on the official zoning map (§ 12-3.02) .

R-1 (Single-Family Residential)

Purpose: Single-family residential development; standards for setbacks, height and yards are provided in the R-1 chapter (§ 12-7.*) .
Typical permitted uses: Single-family dwellings and accessory structures (see the local R-1 chapter; some accessory uses like garages and certain accessory structures are described in § 12-7.10) .
Key dimensional standards (explicit in the retrieved ordinance):
- Maximum building height: 30 ft (§ 12-7.09) .
- Front yard setback: 20 ft (garage exceptions noted in § 12-7.10) .
- Side yards: interior lots 5 ft and 10 ft (one side/other side) and corner-lot side setback 15 ft; zero side yard possible with findings (§ 12-7.10) .
- Rear yard: 10 ft (rear yard adjoining R-1 zone may be 20 ft; alley access exceptions apply) (§ 12-7.10) .
Where it applies: See the official Zoning Map; R-1 rules govern single-family neighborhoods (§ 12-3.02; § 12-7.10) .
Key dimensional standards: The city dimensional matrix includes provisions for M-1, M-2 and CM (matrix in retrieved materials) but a controlling § for the matrix is not shown in the snippets (Not found in retrieved materials) .
Where it applies: See zoning map (§ 12-3.02) .

PF (Public Facilities and Institutional)

Purpose: Public/institutional uses (listed in § 12-3.01) .
Typical permitted uses: Schools, government facilities, hospitals (specific list not reproduced in retrieved snippets).
Key dimensional standards: Not found in retrieved materials.
Where it applies: See zoning map (§ 12-3.02) .

SP (Specific Plan Zoning District; e.g., Entrada Specific Plan)

Purpose: Areas governed by a Specific Plan (the ordinance references the Entrada Specific Plan (SP-1) and makes the plan and map part of the regulatory framework) (§ 12-3.04) .
Typical permitted uses & standards: Specific plans carry their own development standards; see the Entrada Plan map and the SP text (file on record referenced by the code) (§ 12-3.04) .
Where it applies: Only where an SP is adopted and mapped (§ 12-3.04) .

AS-I, AS-II, AS-III (Airport Service I–III) and AA (Airport Approach)

Purpose: Airport-adjacent service zones and approach combining rules; these appear in the district list and overlay list (§ 12-3.01) .
Typical permitted uses: Airport‑related services; AA contains approach/combing regulations for safety and approach compatibility (details appear in the AA chapter; adoption referenced in district list) .
Key dimensional standards: Not found in retrieved materials.
Where it applies: As mapped on the Zoning Map (§ 12-3.02) .

PD (Planned Development) and PD-f (Planned Development/Freeway Tower)

Purpose: Overlay districts to allow flexible, site‑specific development standards where a project is subject to a Planned Development permit (§ 12-25.03) .
Typical permitted uses: The PD symbol is combined with an underlying zone (e.g., PD/R-2, PD/C-2) and generally permits the uses of the underlying zone subject to the approved PD permit; the ordinance lists a number of uses explicitly allowed in PD districts and allows the Planning Commission to modify setbacks adjacent to R districts with required findings (§ 12-25.03) .
Key dimensional standards: PD permits are used to set project-specific standards; the ordinance explicitly allows modifications of setbacks and heights through PD findings (§ 12-25.03) .
Where it applies: Wherever PD overlay has been applied on the official zoning map (§ 12-3.02) .

H (Historic Overlay)

Purpose: Promote orderly, attractive and harmonious development in designated historic areas; the H overlay combines with base zoning and typically requires development plan approval (§ 12-25A.04; § 12-25A.05) .
Overlays matter: a property mapped H or PD will be evaluated under overlay rules and may require development plan approval even for otherwise-permitted uses (§ 12-25A.*; § 12-25.03) .
Small numeric differences (setbacks, height) often appear in the specific chapter for the base zone — the R-1 chapter explicitly states 20 ft front setback and 30 ft height (§ 12-7.10; § 12-7.09) — use those code sections to draft your site plan first .
If the ordinance text allows exceptions (for example, PD, CUP or Administrative Use Permit modifications), the code sets the maximum ranges of modification (example: the Zoning Administrator may permit minor exceptions up to 10%; Planning Commission up to 25%, larger deviations require Council) — see the code on adjustments and PD procedures (§ 12-49.04(a) notes in the snippets) .

Checklist — what an applicant must confirm / provide (minimum)

Confirm parcel district on the official Zoning Map (§ 12-3.02) .
Determine whether the use is Permitted (P), Conditionally Permitted (CUP/PD) or Not Allowed in that base district (see the district chapter or use matrix — § 12-3.01 and relevant chapter) .
Confirm dimensional standards that apply to your lot (for R-1: front 20 ft, side 5/10 ft, rear 10 ft, height 30 ft — § 12-7.10; § 12-7.09) .
Check parking requirements (Chapter 12-32) and whether a mixed‑use reduction or administrative reduction applies (mixed-use rules in Chapter 12-49) — see Santa Maria Parking for guidance and § 12-49 notes in the code .
If property is inside an overlay (H, PD, AA, etc.) prepare for overlay-specific approvals (historic overlay requires a development plan — § 12-25A.*; PD requires a PD permit — § 12-25.03) .
If design review applies (the ordinance references design standards and guidelines for C-1 areas and other review processes), prepare elevations and materials for review — see Santa Maria Design Review and the code references to design guidelines (§ 12-3.04) .
Ensure landscaping and screening proposals meet the code's landscaping rules (tree replacement, percent open space for commercial/multi-family) — see § 12-? (landscaping requirements referenced in the code; see landscaping chapter) .
Confirm whether your proposal requires an Administrative Use Permit, Conditional Use Permit, Planned Development Permit, or referral to the Zoning Administrator / Planning Commission (§ 12-35.301–.303; § 12-25.03) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Which numeric standards apply outside R-1	The ordinance text snippets clearly list R-1 numeric standards but the dimensional matrix's section number is not shown in the retrieved snippets	Verify the controlling dimensional table/section for your base zone on the official code (see the zoning district dimensional standards table in the municipal code) — Verify with the jurisdiction.
Overlay requirements (H, PD)	Overlays can impose design-review/dev-plan approval even when the underlying use is permitted	Confirm whether overlays map to your parcel and read § 12-25A.* (H) and § 12-25.03 (PD) — Verify with the jurisdiction.
Mixed-use allowances and parking reductions	Mixed-use projects have special rules and allowed parking reductions that affect feasibility and parking design	Check Chapter 12-49 for mixed-use rules and Chapter 12-32 for parking; mixed-use reductions require specific findings (§ 12-49.; § 12-32.*)
Parcel-specific exceptions & deviations	The code allows administrative and Commission-level exceptions (10%/25%) which affect building envelopes	If you expect to seek a deviation, confirm the exact procedural steps and standards in § 12-49.04(a) and PD/CUP sections — Verify with the jurisdiction.
Lack of explicit § for dimensional matrix in retrieved snippets	Many of the matrix numbers appear in the file preview but the controlling section number for the table wasn't visible in the retrieved excerpts	Look up the Municipal Code online or contact Community Development for the exact section that houses the dimensional matrix — Not found in retrieved materials.

Plain-English Summary

Santa Maria's Municipal Code lists named zoning districts and an official zoning map that controls which land uses and rules apply to each parcel; small-lot single-family neighborhoods use R-1 rules (including 20 ft front setbacks and 30 ft height limits (§ 12-7.10; § 12-7.09)), commercial and industrial zones follow the municipal dimensional matrix, and overlays like PD and H layer additional approval requirements on top of the base zone (confirm your parcel's map designation and the corresponding sections in the code) .

Frequently asked questions

What can I build on an **R-1** lot in Santa Maria?

Most typical single-family residential uses and accessory structures are the intended uses in R-1; numeric controls for R-1 in the code include a 20 ft front setback (with garage exceptions), side yards 5 ft/ 10 ft, rear 10 ft, and a maximum height of 30 ft — see § 12-7.10 and § 12-7.09 for the R-1 rules .

Where do I check the official zoning for my parcel?

The legal zoning assignment is the City’s official Zoning Map incorporated by reference in the code — confirm your parcel’s district under § 12-3.02 and with the Community Development Department (map dated and amended) .

Do I need a Planned Development (PD) permit to change setbacks or density?

If the property is mapped PD or you are proposing deviations that require a PD, the PD process is the vehicle to set site-specific standards; the code allows the Planning Commission to modify side and rear setbacks adjacent to an R district when required findings are met (§ 12-25.03) .

Are historic overlays (H) just a label or do they trigger extra review?

The H overlay requires a development plan approval process for changes in H areas and can require additional findings and design review even if the underlying use is otherwise permitted (§ 12-25A.04 – 12-25A.06) .

Where are mixed-use and live-work rules found and do they affect parking?

Mixed-use and Live-Work/Work-Live rules are in Chapter 12-49 (for example § 12-49.06 covers live-work units). Mixed-use projects follow Chapter 12-32 parking rules but the code allows administrative and Planning Commission reductions (10% / up to 25%) under stated conditions (§ 12-49.*; Chapter 12-32 referenced) .

Can I get a small modification to setback or height without going to the Planning Commission?

The code allows limited deviations: an Administrative Use Permit (Zoning Administrator) may grant minor exceptions up to 10% of height/setback maximums; the Planning Commission may grant up to 25% via CUP or PD; larger deviations require City Council action (see the code notes on exceptions) — see § 12-49.04(a) for the exception framework (as referenced in the municipal code excerpts) .

If my lot is in a Specific Plan (SP), which rules control?

Where a Specific Plan (SP) applies, the Specific Plan's standards and map take precedence for that area — the code references the Entrada Specific Plan (SP-1) as an example and incorporates the plan by reference (§ 12-3.04) .

What role does the Zoning Administrator play for use permits?

The Zoning Administrator (the Community Development Director or designee) has delegated authority to process certain use permits administratively for specified uses (examples include small residential developments, churches, light manufacturing, live-work in existing buildings, etc.) — see § 12-35.301 – § 12-35.303 for the Zoning Administrator powers and procedures .

Does Santa Maria’s zoning code include a dimensional matrix for most zones?

Yes — the Municipal Code excerpts include a Zoning District Dimensional Standards matrix showing heights and setbacks for a number of zones (for example R-2, R-3, CPO, CC, C-1, C-2, M-1, CM appear in the retrieved matrix). The specific section number for that matrix was not visible in the retrieved snippets (Not found in retrieved materials) — consult the full Municipal Code or Community Development to retrieve the exact section and table on which to base your design .

If I want an ADU, what zoning rules matter in Santa Maria?

ADU rules are primarily governed by state ADU law, but local zoning still controls basic siting (setbacks, overlays, and parking exceptions). The municipal code cross-references state allowances (see the City's ADU guidance and the state codes); consult both the local ADU chapter and the California ADU law and Santa Maria ADUs pages when preparing an ADU application. For mixed-use/parking relief and nonconforming issues the municipal code also references these topics (see § 12-49.* and related ADU cross-references) .
