Fullerton — Land Use
Land Use under the Fullerton local zoning and planning code, with the controlling citations.
Quick answer
Only expressly allowed uses may occur in each zone (§ 15.56.020). In commercial districts, street setbacks are 10–15 ft (garage doors 25 ft) with a 1:1 stepback above 10 ft next to residential (§ 15.30.050). Industrial buildings are capped at 45 ft with similar adjacency stepbacks and at least a 10 ft setback by homes (§ 15.40.040). PRD‑I infill uses 5 ft alley setbacks and street‑type‑based frontages (§ 15.20.140).

Overview
Fullerton regulates what you can do on your land through its Zoning Ordinance (Title 15). Only uses expressly allowed in each zone may occur, and anything not listed is prohibited unless determined to be a similar permitted use. Land use decisions also hinge on district-specific development standards, adjacency rules, and special plan areas. Start by confirming your parcel’s zoning on the city’s map and then match your proposed use to the zone’s allowances.
Core rule: A property in Fullerton may be used “only for a purpose specifically permitted in the zone in which such building or land is located” (§ 15.56.020).
How Fullerton organizes land use
- The zoning map establishes each parcel’s zone classification (§ 15.08.040). Check your mapped zone before anything else. See the Fullerton Zoning page for help.
- Residential uses are governed by the R-1 through R-5 and R-MH districts, with a detailed permitted-use matrix (§ 15.17.020) and zone purposes (§ 15.17.015).
- Commercial uses occur in O-P, G-C, C-3, and C-M, with dimensional standards such as setbacks and height adjacency in § 15.30.050.
- Industrial uses occur in M-P and M-G with uses defined by NAICS, parking ratios, setbacks, and environmental performance standards (§§ 15.40.020, 15.40.040, 15.40.050, 15.40.080).
- Planned/innovative residential infill is guided in PRD‑I with building type, frontage, height, and setback tables keyed to street type (§§ 15.20.130, 15.20.140).
- City facilities and compatible activities locate in P‑L, largely by conditional use permit (§ 15.25.025).
- Some areas are further shaped by plan/overlay rules (e.g., Central Business District, Airport Environs, Restaurant Overlay). See Fullerton Overlay Districts.
Use approvals can include ministerial clearances (when fully conforming), design review or site plan review, or a Conditional Use Permit (CUP) when a use is allowed “by CUP” (§ 15.70.020).

- Parking: Ratios by use (e.g., general manufacturing 1/800 sf, warehousing 1/2,000 sf, office 1/250 sf), with carpool/vanpool and visitor space requirements (§ 15.40.050). See Fullerton Development Standards.
P‑L (Public Land)
- Purpose: City, school, and public-use lands.
- Uses: Certain non-public activities may be allowed by CUP, including open-air markets, commercial agriculture/non-retail nurseries (excluding cannabis), and “special uses” except those specifically excluded (§ 15.25.025).
- Key standards: Not found in source materials; apply adjacency and general provisions as relevant (§ 15.56.010).
Cross-cutting residential allowances
- ADUs/JADUs: Allowed citywide in residential zones, with ministerial approval when standards are met. Highlights include no ADU parking requirement and specific unit-count limits on multifamily sites (e.g., up to 25% of existing units for MF with 8+ units). Setbacks for certain ADU expansions are 4 ft at side/rear; front must follow the base zone (§ 15.17.100).
- Two‑unit housing (SB 9): Only in R‑1 and subject to location exclusions (e.g., mapped historic districts) and deed restrictions; rentals must be 31+ days (§ 15.17.130). See California housing laws and Fullerton ADUs for related topics.
Process notes that affect land use
- Similar-use findings: In residential zones, unlisted uses are prohibited unless determined similar and consistent with the zone’s purpose by the Director (§ 15.17.020(C)). Industrial uses rely on NAICS determination by the Director, appealable per Chapter 15.76 (§ 15.40.020(A)(3)).
- CUPs: If your use is marked “CUP” (e.g., certain industrial uses, residential care facilities over 6 persons), you must file a CUP application with required submittals and fees (§ 15.70.020). See Fullerton Variances and Exceptions for relief mechanisms distinct from CUPs.
- Site/Design review: Industrial projects require site plan review (§ 15.40.030); other projects may trigger design review or site plan review under Chapter 15.47 (§ 15.47.050).
Practical tips
- Adjacency matters: Commercial and industrial buildings must “step back” one foot for every foot of height above 10 feet when next to residential—this often controls massing more than base height limits (§§ 15.30.050(B)(1), 15.40.040(C)(2)).
- Street-context in PRD‑I: Street type drives what building/frontage types you can use and how tall they can be (e.g., shopkeeper types limited to major/primary arterials up to 3 stories) (§ 15.20.130).
- Parking design: Beyond quantity, drive aisles and stall geometry must meet the tables in § 15.30.070; coordinate early with your parking layout.
Checklist
- Confirm your parcel’s mapped zone and any overlay or district designation (§ 15.08.040). See the Fullerton zoning & planning overview.
- Identify whether the proposed land use is permitted, CUP, or not permitted for that zone: residential matrix (§ 15.17.020); industrial NAICS table (§ 15.40.020).
- If in PRD‑I, select a permitted building type and frontage for your street type; verify max stories and setbacks (§§ 15.20.130, 15.20.140).
- Apply zone development standards that affect site layout (commercial § 15.30.050; industrial § 15.40.040). See Fullerton Development Standards.
- Validate parking ratios and geometry (residential § 15.17.080; industrial § 15.40.050; access/aisles § 15.30.070).
- Determine if design review or site plan review is required (industrial: § 15.40.030; general: § 15.47.050).
- If a CUP is needed, prepare application materials and fees (§ 15.70.020).
- For ADUs or SB 9 two‑unit projects, confirm zone eligibility and apply standards (§§ 15.17.100, 15.17.130).
- Check for overlays that can modify standards (CBD, Restaurant Overlay, Airport Environs) and any signage or landscaping and screening requirements.

|---|---|---|
| Residential dimensional standards not provided | Setbacks/height/FAR can control feasibility | Not found in source materials; Verify with the jurisdiction |
| Commercial permitted uses list missing | Use may be prohibited or need a CUP | Not found in source materials; confirm allowed uses in Chapter 15.30 |
| Interpreting PRD‑I tables | Street class affects building type, frontage, height | Confirm your frontage street classification and apply § 15.20.130/§ 15.20.140 |
| NAICS classification for industrial | Determines if use is “X” or “CUP” | Director’s determination per § 15.40.020(A)(3) |
| Overlay boundaries and exceptions | CBD setbacks, Restaurant Overlay parking, Airport height | Confirm overlay maps/policies; apply § 15.30.050(C)(2), § 15.40.050(A), § 15.40.040(C)(3) |
| Adjacency stepbacks | Massing next to residential often drives design | Apply 1:1 stepback above 10 ft (commercial § 15.30.050(B)(1); industrial § 15.40.040(C)(2)) |
| Outdoor storage visibility | Industrial yards must be screened | Screening to fully obscure from ROW (§ 15.40.020(D)) |

Plain-English Summary
Fullerton ties what you can do on your property to your mapped zone. Homes and ADUs are allowed in residential zones per a citywide matrix; offices/retail occur in commercial zones subject to street setbacks and special downtown rules; and industrial uses are checked against NAICS codes with parking, screening, and environmental limits. Projects near homes must step back upper stories, and infill PRD‑I areas follow form-based tables that match building types to street types.

Frequently asked questions
What can I build on an R-1 lot in Fullerton?
A single-family home is permitted, and you may add an ADU/JADU if you meet ADU standards (§ 15.17.020; § 15.17.100). A two‑unit (SB 9) project is also possible on R‑1 if the site is eligible and you record the required deed restriction, with rentals of 31+ days (§ 15.17.130).
Are duplexes allowed in Fullerton?
Yes—on R‑2 and R‑2P lots, two‑family dwellings are permitted (§ 15.17.020; § 15.17.015(C),(D)). Duplexes are not listed as permitted in R‑1/R‑1P; consider SB 9 two‑unit provisions on eligible R‑1 sites (§ 15.17.130).
Do I need a CUP for my industrial use?
Maybe. Industrial uses are classified by NAICS; uses marked “X” are permitted, while those marked “CUP” require a Conditional Use Permit (§ 15.40.020(B)(2)). The Director assigns the proper NAICS, subject to appeal (§ 15.40.020(A)(3)).
How tall can an industrial building be?
Up to 45 ft generally (§ 15.40.040(C)(1)). If your site abuts residential, any portion above 10 ft must step back one foot for every foot of extra height, with at least a 10 ft setback at the boundary (§ 15.40.040(C)(2)).
What setbacks apply to offices and shops?
Along public streets: O‑P requires 15 ft, while G‑C/C‑3/C‑M require 10 ft; garage doors must set back 25 ft in all cases (§ 15.30.050(C), Table 15.30.050(A)). Downtown C‑3 street setbacks can be waived under CBD guidelines (§ 15.30.050(C)(2)).
What are PRD‑I form standards?
PRD‑I ties allowed building types and frontages to street classes (e.g., rowhouses on neighborhood streets, shopkeepers on major arterials) with max stories by type/street and context‑based setbacks (e.g., 5 ft to alleys; 15/20 ft rear next to R‑1/R‑2) (§§ 15.20.130, 15.20.140).
How does parking get evaluated in industrial zones?
By use category: e.g., general manufacturing 1 space/800 sf, warehousing 1/2,000 sf, office 1/250 sf, plus carpool/vanpool and visitor-space requirements (§ 15.40.050). Drive aisles and stall sizes follow § 15.30.070.
Are outdoor storage yards allowed?
Yes, in industrial zones where buildings are allowed, but they must be fully screened from streets and adjacent properties so they aren’t visible from public rights‑of‑way (§ 15.40.020(D)).
Can I rely on an unlisted residential use if it’s similar?
Only if the Director determines it is similar to a listed permitted use and consistent with the zone’s purpose; otherwise unlisted uses are not permitted (§ 15.17.020(C)).
Do commercial buildings have height limits?
If not adjacent to (or across an alley from) residential or located in a public parking district, height is unlimited, though FAR may control massing; next to residential, a 1:1 stepback above 10 ft applies (§ 15.30.050(B)).
