Cerritos — Development Standards
Development Standards under the Cerritos local zoning and planning code, with the controlling citations.
Last reviewed: July 3, 2026
Overview
This page summarizes the City of Cerritos rules that control development standards — setbacks, maximum building coverage, height, density, and floor area ratio (FAR) — as written in the local zoning and area development plan chapters of the Cerritos municipal code. For the citywide regulatory framework see the Cerritos zoning & planning overview and for the underlying ordinance text consult the Cerritos Zoning references. This page focuses only on the local zoning provisions (Title 22/Title 17 style chapters in the uploaded ordinance) that set measurable site and intensity limits; building-code matters remain governed by the California Building Standards Code.
How to read this page
- Bold indicates the exact district names and numeric limits found in the ordinance (not model placeholders).
- The code citations use the § symbol followed by the ordinance number (for example, § 22.22.600) and are backed by the uploaded code excerpts cited inline.
- Where the ordinance is silent or parcel‑specific, the guidance notes “Verify with the jurisdiction.”
District-by-district development standards
Below are the districts and area development plans that are explicitly covered in the retrieved ordinance excerpts. Each subsection gives the purpose/typical uses, the most consequential dimensional/intensity controls and where those rules apply.
RS (single-family residential; includes RS-5000 and RS-6500)
- Purpose / Typical uses: Single‑family detached housing; the code distinguishes RS-5000 and RS-6500 lot standards for minimum frontage, lot width, and lot area. See the RS rules for single-family intensity limits.
- Key standards:
- Maximum building coverage: 40% of lot area (can be increased to 45% for certain RS-5000 lots under criteria) — § 22.22.600(2) .
- FAR: 0.70 (both RS-5000 and RS-6500) — § 22.22.600(3) .
- One dwelling unit per lot (no duplexing except where other specific plans allow) — § 22.22.600(1) .
- Minimum street frontage / lot width / lot area: RS-5000: 50 ft frontage and 50 ft lot width baseline; RS-6500: 60 ft frontage and 60 ft lot width baseline (exceptions allowed for cul‑de‑sacs and special situations) — § 22.22.700(1)-(2) .
- Setbacks and yard rules governing projecting features, eaves, trellises, garage parking counts and driveway dimensions are in the RS site development rules (see § 22.22.700 for details) .
- Where it applies: typical single‑family neighborhoods and RS-designated tracts; verify the specific RS subcategory for your parcel because RS-5000 and RS-6500 have different frontage and area minima — § 22.22.700 .
(First mention of the city's zoning program above links to the City’s broader Zoning page for related maps and zone tables.)
CN (Neighborhood Commercial)
- Purpose / Typical uses: Small-scale commercial and retail serving nearby residents; the CN chapter lists permitted and prohibited uses and contains intensity/site rules. See § 22.25.110–.500 for permitted/prohibited uses (examples in the code).
- Key standards:
- Maximum building coverage: 50% of parcel area — § 22.25.600(1) .
- Maximum FAR: 0.60 (60% floor area to parcel ratio) — § 22.25.600(2) .
- Adjacent street setback: 25 ft landscaped setback along full street frontage (reducible to 20 ft on certain small legal corner parcels) — § 22.25.700(1) .
- Side/rear setbacks from residential areas: 24 ft minimum (with limited reductions under strict conditions including 20 ft max building height and dense landscaping) — § 22.25.700(2)(a) .
- Parking quantitative rules appear in the CN site rules (e.g., retail/office space parking ratios) — see § 22.25.700(8) for parking requirements and detailed counts .
- Where it applies: parcels zoned CN. See the code chapter for prohibited uses and conditional exceptions — § 22.25.500–.700 .
(When you need to check vehicle stall counts and layout, consult the Cerritos Parking standards and the CN chapter references above.)
Manufacturing‑Office (industrial/office park standards)
- Purpose / Typical uses: Manufacturing, light industrial, office‑park style uses with special design/landscaping and storage containment rules.
- Key standards:
- Building coverage: 50% typical; parcels with parking structures that front an interior street may qualify for 75% lot coverage overall for buildings and parking structures; for parcels with parking structures the building component is limited to 50% — § 22.11.220 .
- Front setback: 33 ft fully landscaped setback from curb face; no parking in that setback — § 22.11.230(3)(A) .
- Building height: No greater than 16 ft within 50 ft of the curb face and in no case more than 35 ft overall (special allowances for parking structures under overlay rules) — § 22.11.230(4) .
- Storage and refuse containment must be fully enclosed and screened (concrete masonry walls required) — § 22.11.230(6)-(7) .
- Design quality can be referred to the city's design review committee (see § 22.11.230(5) which references design review procedures) — § 22.11.230(5) .
- Where it applies: parcels designated manufacturing‑office (refer to the zoning map and precise plan requirements).
(First mention of design controls above links to Cerritos Design Review.)
ADP (Area Development Plans) and Overlays — examples: ADP‑5.1, ADP‑17, ADP‑21, etc.
- Purpose / Typical uses: ADPs are site‑specific planning overlays that can replace or augment base zone rules to achieve coordinated development on complex parcels (shopping centers, large tracts, Auto Square). The code repeatedly states the ADP can control when in conflict. See the ADP chapters.
- Key rules and examples:
- ADPs may set their own density, coverage, setbacks, public open space and private usable open space standards; they often allow the approving authority to permit minor deviations during precise plan review — see § 22.34.130–.140, § 22.36.130–.140, § 22.52.130–.140, and § 22.56.130–.140 for different ADP areas and how they treat density, building coverage and setbacks .
- Example: ADP‑5.1 (Auto Square overlay) imposes special vehicle display rules, sets building coverage to 50% (or up to 65% for existing buildings exceeding the max), prescribes display parking structure heights up to 5 stories or 70 ft west of Studebaker, and requires 25 ft setbacks on certain frontages — § 22.61.110(2)-(4) .
- Example: ADP‑21 (Los Cerritos Center area) sets multi‑family density between 30 and 80 units per net acre, building coverage up to 60%, and requires technical studies for by‑right projects with affordable units — § 22.56.130–.140 .
- Where it applies: parcels mapped to an ADP overlay; where an ADP conflicts with the underlying zone, the ADP standards control — § 22.61.110 (ADP wording on controlling standards) .

Quick standards table (decision‑relevant excerpt)
| District / Plan | Key controls (setback / coverage / FAR / height / density) | Code Reference |
|---|---|---|
| RS (single‑family; RS‑5000 / RS‑6500) | Building coverage 40% (up to 45% in limited RS‑5000 cases); FAR 0.70; one dwelling per lot; lot frontage/width minima: 50 ft / 50 ft (RS‑5000) or 60 ft / 60 ft (RS‑6500) | § 22.22.600–700 |
| CN (Neighborhood Commercial) | Building coverage 50%, FAR 0.60, adjacent street setback 25 ft (landscaped), side/rear to residential 24 ft | § 22.25.600–700 |
| Manufacturing‑Office | Building coverage generally 50%; up to 75% where parking structure permitted; front setback 33 ft; height limit 16 ft within 50 ft of curb and 35 ft overall | § 22.11.220–230 |
| ADP‑5.1 (Auto Square) | Building coverage 50% (up to 65% if existing exceed), special display structure height ≤ 70 ft / 5 stories (west of Studebaker); front setback 25 ft for display uses | § 22.61.110 |
| ADP‑21 (Los Cerritos Center) | Residential density 30–80 units/acre, building coverage ≤ 60%, public open space and tech studies required for by‑right affordable projects | § 22.56.130–140 |
Note: the city has many ADPs (22.34, 22.36, 22.52, etc.) each with its own coverage/setback/FAR rules; always check the ADP that maps to the parcel — e.g., § 22.34.130–140 (ADP ten) and § 22.36.130–140 (ADP twelve) for additional numeric standards .
Synthesis & practical guidance
- Base zone intensity standards (building coverage, FAR, maximum units) are expressed in the zone/ADP chapters (example: § 22.22.600 for RS, § 22.25.600 for CN) and are the first limits you must meet when designing a project .
- Area Development Plans (ADPs) are common in Cerritos and frequently supersede or refine base zone rules for large parcels; when an ADP applies its standards govern if there is a conflict (see § 22.61.110) .
- Many ADP chapters expressly allow the approving authority to permit "minor deviations" at precise‑plan review when consistent with the plan’s intent; anticipate negotiation on setbacks/building offsets rather than absolute uniform outcomes (§ 22.34.140, § 22.36.140) .
- For site layout you must also satisfy landscaping/screening and parking rules; parking rates and design details are quoted in zone/ADP site standards (for example, parking minimums in the RS ADP provisions and CN chapter) — consult the local Parking page as part of preliminary design and the specific code clauses (e.g., § 22.22.700(9) and § 22.25.700(8)) .
- Accessory Dwelling Units (ADUs) are governed by state ADU law which limits how local setbacks and sizes may be imposed; local ADU provisions must be read together with state law — see the city's ordinance where it interacts with state rules and the California ADU guidance for preemption notes (state guidance in the uploaded ADU handbook) . (First mention of ADUs linked to the Cerritos ADUs page.)

Checklist
- Confirm the parcel's zoning district and any ADP/overlay that applies (zoning map + overlay map). Verify the ADP chapter number that maps to the parcel (e.g., ADP‑5.1, ADP‑17, ADP‑21) — § 22.61.110 for overlay precedence .
- Confirm intensity limits applicable to the parcel (maximum dwelling units, building coverage, FAR) per the applicable zone or ADP (examples: § 22.22.600, § 22.25.600, § 22.56.130) .
- Confirm site development standards: setbacks, minimum frontage / lot width / lot area, maximum building height, and any building spacing or offset rules (see RS site rules § 22.22.700, ADP site sections like § 22.34.140 or § 22.36.140) .
- Check parking stall counts, stall dimensions, and location rules in the relevant zone/ADP chapter (see CN and RS provisions) and the city's parking rules — § 22.25.700(8), § 22.22.700(9) .
- Determine whether design review or precise plan approval is required (many manufacturing/ADP projects reference the design review committee procedures) — see § 22.11.230(5) and applicable ADP precise plan language .
- For ADUs, confirm local objective standards do not conflict with state ADU law — consult the municipal ADU chapter and state ADU guidance (uploaded ADU handbook) .
- Confirm nonconforming status and reconstruction rules if the existing improvements are nonconforming — § 23.50.300 .

Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| ADP vs. underlying zone conflicts | ADPs frequently override base zone rules; relying on base zone numbers alone can produce an incorrect program | Check whether the parcel is in an ADP (see § 22.61.110) and use the ADP chapter as controlling where it conflicts with the underlying zone |
| “Minor deviations” and discretionary precise plan approvals | The approving authority can grant deviations; project outcomes may depend on findings and design quality | Verify the approval body (director, planning commission, city council) and the precise criteria in the ADP or precise plan chapter (see § 22.34.140, § 22.36.140) |
| ADU setbacks vs. state law | State ADU law limits what local setbacks/sizes may prevent — local rules that appear strict may be preempted | Cross‑check local ADU chapter with state ADU law and the ADU handbook; where ambiguous, “Verify with the jurisdiction” and cite state guidance |
| Parcel‑specific mapping (ADP boundaries) | ADP numeric standards are area‑specific — the same street can have different standards on different parcels | Confirm the precise ADP map / parcel designation on the city zoning map; do not assume a district name without map confirmation (Verify with the jurisdiction) |
| Nonconforming structure treatment | Rules limit enlarging or relocating nonconforming structures; reconstruction triggers full compliance in many cases — this can affect feasible additions or ADUs | Confirm status under § 23.50.300 and whether reconstruction to original nonconformity is allowed; ask the planning department for an official determination |

Information Gaps
- The uploaded excerpts include many ADP chapters and zone snippets but do not present a single consolidated numeric table containing every base zone (e.g., a full Title 17-style table of all R‑1/R‑2/R‑3 commercial and industrial zones). Verify the full zone table and the official zoning map with the city. (Not found in retrieved materials.)
- Detailed, citywide yard/setback tables for every conventional zone (a concise R‑1/R‑2/R‑3 set) were not clearly present in the retrieved excerpts; several numbers are in ADP chapters only. Verify the standard setbacks in the base zoning tables from the city's full code or zoning map (Verify with the jurisdiction).
- Any recent ordinance amendments adopted after the uploaded file snapshot may not be included here — always check the city’s current online municipal code.
Plain-English Summary
Cerritos sets measurable caps on lot coverage, FAR, height, and setbacks in each zone and in many site‑specific Area Development Plans (ADPs); ADP rules typically control where they conflict with base zone rules, and precise plan or design‑review processes frequently allow limited deviations if justified — always check the parcel’s zone + any ADP overlay and read the corresponding chapter (e.g., § 22.22.600 for RS rules, § 22.25.600 for CN, § 22.61.110 for overlay precedence) .

Frequently asked questions
What can I build on an R‑zone lot in Cerritos?
You must follow the specific RS rules that apply to your parcel (e.g., RS‑5000 or RS‑6500). Generally the code allows one single‑family detached dwelling per lot, limits building coverage to 40%, and caps FAR at 0.70; frontage, width and lot area minima differ for RS‑5000 vs RS‑6500 — see § 22.22.600–700 for exact numeric tests and exemptions .
What are Cerritos setback requirements for single‑family homes?
Setbacks and yard rules vary by RS subzone and by any area development plan that may overlay the lot. The single‑family site development rules (RS chapters/ADPs) contain front, side, rear, and projection allowances and minimums — consult § 22.22.700 for RS minima and the applicable ADP chapter if your property lies inside an ADP .
Do ADP overlays change the base zone development standards?
Yes. When an ADP applies and contains site development standards, the ADP’s standards control where they conflict with the underlying zone; the overlay chapters explicitly state that the ADP standards apply in case of conflict — § 22.61.110 .
What is the maximum building coverage in commercial zones like CN?
In the CN zone building coverage is limited to 50% and FAR is limited to 0.60 under the CN intensity chapter; adjacent street setbacks and enhanced side/rear setbacks next to residential areas are also specified — § 22.25.600–700 .
Are there floor area ratio (FAR) limits in Cerritos?
Yes. Several zones and ADPs specify FAR limits (for example FAR 0.70 in some residential rules and FAR 0.60 in CN); some ADPs specify percent floor area differently or express limits as floor area percentages (see § 22.22.600, § 22.25.600, § 22.12.160(3)) .
Will the city allow small deviations from published setbacks or coverage limits?
Many ADP and precise plan chapters explicitly permit the approving authority to allow minor deviations when the change conforms to the spirit of the plan and is justified in findings; check the ADP or precise plan chapter for the parcel (examples: § 22.34.140, § 22.36.140) .
How are parking requirements set for new projects?
Parking minimums and stall dimensions are specified in the applicable zone or ADP site development section (for example RS ADP rules and CN chapter include parking counts and sizes). Always check the chapter for the parcel and the city’s parking rules; see the CN parking rules in § 22.25.700(8) and RS parking language in RS site rules (e.g., § 22.22.700(9)) .
If my building is nonconforming, can I add an ADU or reconstruct?
Nonconforming structures have limits on enlargement and moving; reconstruction after destruction may require compliance. The nonconforming section explains reconstruction and limitations — see § 23.50.300. For ADUs, state ADU law also constrains local treatment, so check both the nonconforming rules and ADU rules (local + state guidance) .
Is design review required for commercial or industrial projects?
Many manufacturing/office and ADP precise plans reference design review and may refer projects to the design review committee as part of the discretionary approvals (see § 22.11.230(5)). If your project triggers a precise plan or is in an ADP that requires architectural consistency, expect design review to be part of approvals — § 22.11.230(5) .
Where do I find ADP‑specific density numbers (e.g., Los Cerritos Center)?
ADP chapters give parcel‑specific density, coverage and open‑space requirements. For example, ADP‑21 (Los Cerritos Center) sets residential density between 30 and 80 units per net acre and building coverage up to 60% — § 22.56.130–140 . ---
