Fresno County — Zoning
Zoning under the Fresno County local zoning and planning code, with the controlling citations.
Last reviewed: July 3, 2026
Overview
This page summarizes how Fresno County's Zoning Ordinance (Division 6 of the County Ordinance Code, commonly titled the Zoning Ordinance / Title 17 implementation) regulates land use and development in the unincorporated areas of Fresno County. It explains the primary zone groups, where to read the tables that list permitted uses, and the most decision-relevant dimensional and process standards you will encounter when working on an unincorporated parcel. The zoning rules implement the General Plan and are enforced via the County's site plan, director, conditional-use, and map amendment procedures (verify parcel-specific details with the County) .
How the ordinance is organized and what to check first
- The official Zone Map is incorporated by reference and controls district boundaries for unincorporated areas; start by confirming your parcel's zone on the County Zone Map (§ 806.2.020) .
- What uses are allowed and what permit type is required are listed in the zone-specific use tables (Article 2: Chapters 808.2–819.2) — look for "P", "C", "D", "SPR", or "TUP" in those tables (§ 806.2.030) .
- Dimensional standards (minimum parcel sizes, setbacks, height, and lot coverage) are provided in the zone tables (e.g., Table 2‑3 for agricultural zones; Table 2‑4 for residential zones) and the general development standards in Article 3 (e.g., setbacks, fences, screening, parking) (§ 808.2.040, § 810.2.030, Chapters 820–830) .
- Projects commonly require Site Plan Review or other discretionary approvals (see Chapter 854.5); building permits come later and must also comply with the California Building Standards Code (Title 24) (§ 806.2.030, § 800.1.040) .
Important internal County pages you will likely use while preparing an application include links on parking, development standards, overlays, design review, and other topic pages such as Fresno County Parking, Fresno County Development Standards, Fresno County Design Review, and Fresno County Overlay Districts.
District-by-district (selected, decision-relevant) — each applies only in the unincorporated areas
Note: the ordinance contains full use tables for every district (see Article 2). Below are the commonly used zones and the most practically relevant rules for applicants. All quoted program headings and standards below are grounded in the cited Fresno County ordinance sections.
AE (Agricultural Exclusive)
- Purpose: The AE zone protects agricultural land and allows farm operations while minimizing non‑agricultural encroachment; acreage designations (e.g., AE‑20, AE‑40, up to AE‑640) set the minimum parcel size (§ 808.2.010) .
- Typical permitted uses: farming, crop production, agricultural accessory structures; additional uses and permit type are shown in Table 2‑2 (Agricultural use table) (§ 808.2.020) .
- Key dimensional standards: minimum parcel size = 20 acres or the acreage designation shown (e.g., AE‑160); maximum main structure height = 35 ft (see Table 2‑3) (§ 808.2.040, Table 2‑3) .
- Where it applies: large farmland and irrigated agricultural designations on the County Zone Map; check Williamson Act contract rules for parcels under contract (§ 808.2.030) .
AL (Limited Agricultural)
- Purpose: The AL zone allows agricultural uses but limits more intensive activities incompatible with surrounding farms (§ 808.2.010) .
- Uses & approvals: Similar to AE but the ordinance identifies specific accessory and conditional uses in Table 2‑2; farmworker housing/temporary farmworker housing allowances are tied to AE and AL in special use sections (§ 834.4.130) .
- Dimensional standards: minimum parcel size = 20 acres (or acreage designation); main structure height = 35 ft per Table 2‑3 (§ 808.2.040) .
R-R (Rural Residential)
- Purpose: The R‑R zone provides for large‑lot single‑family residences and limited small‑scale agriculture (§ 810.2.010) .
- Uses: Single family dwellings, accessory structures, limited agricultural accessory uses as listed in Table 2‑4 (§ 810.2.020) .
- Key dimensions: See Table 2‑4 and the general development standards (setbacks, accessory‑structure rules); typical front setbacks in rural zones are 35 ft, side 20 ft, rear 20 ft unless otherwise stated (§ 810.2.030, § 822.3.100) .
R-1 / R-1-A / R-1-B / R-1-C / R-1-E / R-1-EH / R-1-AH (Single‑Family residential variants)
- Purpose: These R‑1 family of zones accommodate single‑family development with varying lot sizes and special allowances (e.g., horses allowed in R‑1‑EH) (§ 810.2.010) .
- Uses: One primary dwelling per parcel (except planned developments); accessory uses per Table 2‑4 (§ 810.2.020) .
- Dimensional standards: consult Table 2‑4 for zone‑by‑zone minimum parcel size and setbacks; standard front setback often 35 ft in rural/estate variants, urban R‑1 variants have smaller setbacks (see Table 2‑4 and § 822.3.100) .
R-2, R-2-A, R-3, R-3-A, T-P (Multi‑family & manufactured housing)
- Purpose: R‑2/R‑3 family zones allow low‑ to medium‑density multi‑family developments; T‑P is for trailer park/multiple manufactured home communities (minimum site sizes apply) (§ 810.2.010) .
- Uses & process: Multi‑family uses allowed per Table 2‑4; density limits and planned‑development requirements are in the tables and Article 3 standards (§ 810.2.020, Table 2‑4) .
C‑1, C‑2, C‑3, C‑4, C‑6, C‑M, AC, RCC, R‑P (Commercial zones)
- Purpose: The C family covers neighborhood through regional shopping, central trading (C‑4), general commercial (C‑6), specialty commercial centers (e.g., RCC) and transitional R‑P zones (§ 812.2.010) .
- Typical permitted uses: Retail, offices, personal services — each use and permit type is shown in Table 2‑6; some commercial activities require Site Plan Review or conditional use permits (§ 812.2.020) .
- Key dimensions: Commercial setbacks and minimum parcel sizes vary by subzone; e.g., RCC minimum parcel size 2 gross acres, R‑P minimum parcel size 7,500 sq ft, front setbacks down to 10–15 ft in many commercial zones (see Table 2‑7 and § 812.2.030) .
- Special: Emergency shelters are explicitly allowed in C‑4 and C‑M with additional standards (bed limits, intake area, parking) (§ 834.4.130) .
C‑M, M‑1, M‑2, M‑3 (Industrial / commercial‑manufacturing)
- Purpose: M‑1 (Light Industrial), M‑2 (General Industrial), M‑3 (Heavy Industrial), and C‑M (Commercial & Light Manufacturing) assign appropriate industrial uses and buffering expectations (§ 814.2.010) .
- Uses & approvals: Table 2‑8 lists allowed industrial activities and required permits; many industrial uses require Site Plan Review and may require conditional uses for heavier operations (§ 814.2.020) .
- Key dimensions: M‑1 maximum structure height example 75 ft in some special purpose tables; setbacks and parking requirements defer to Article 3 standards (see Table 2‑9) (§ 816.2.030, Tables 2‑9) .
Special Purpose and Overlay / Combining Zones (selected)
- Purpose: O (Open Conservation), R‑C (Resource Conservation), TPZ (Timberland Preserve), and overlays such as -M (Mountain), -NB (Neighborhood Beautification), and -HB (Highway Beautification) apply additional restrictions or modify development standards in mapped areas (§ 816.2, § 818.2) .
- Where overlays apply: Overlays are mapped and recorded on the County Zone Map; overlay standards can change height limits, setbacks, or allowable uses (see § 818.2.030–818.2.080) .
Quick table — decision-relevant snippets (examples)
| Zone (unincorporated areas) | Most relevant baseline standards / permitted uses | Code Reference |
|---|---|---|
| AE | Minimum parcel 20 acres (or acreage designation), main structure 35 ft height; agriculture principal use (Table 2‑3) | § 808.2.040 |
| AL | Minimum parcel 20 acres, 35 ft height; limited intensive uses compared to AE | § 808.2.010 / § 808.2.040 |
| R‑1 (and variants) | Single‑family primary use; front setback commonly 35 ft in rural/estate variants (see Table 2‑4) | § 810.2.010 / Table 2‑4 § 810.2.020 |

(Consult the complete tables in Article 2 for full permitted/conditional use lists — the table cells show "P", "C", "D", "SPR" or are blank for prohibited uses.) § 806.2.030 .
Practical guidance & interpretations (plain English synthesis)
- Always start with the County Zone Map to identify the zone and any overlays; the map is adopted into the ordinance and controls boundaries (§ 806.2.020) .
- Next read the zone's use table (Article 2) to see whether your proposed activity is Permitted (P), allowed with a Conditional Use Permit (C), requires a Director’s Review (D), or needs Site Plan Review (SPR) (§ 806.2.030) .
- Dimension and development standards (setbacks, heights, parcel sizes) are in the zone tables (Table 2‑3/2‑4/2‑7/2‑9) and the Article 3 standards; where the zone table references other sections (for example, fences, screening, parking) those rules apply and are found in Chapters 822.3, 826.3, and 828.3 (§ 808.2.040, § 822.3.090, Chapter 828.3) .
- Overlays and special purpose zones can add or tighten standards (height caps, scenic buffers, historic preservation); check Chapter 818.2 for overlay rules (§ 818.2.030–818.2.080) .
- For housing projects using State programs (density bonus, ADU rules), the County ordinance implements density bonus incentives and must still follow State ADU law; check § 824.3 for local density bonus provisions and consult California ADU law when the project involves accessory units (§ 824.3.020–040) .
Checklist (what an applicant must satisfy for a typical zoning review)
- Confirm parcel zoning and overlay status on the County Zone Map (§ 806.2.020)
- Verify allowable use and required permit type in the zone's Article 2 table (§ 806.2.030)
- Confirm minimum parcel size, frontage, setbacks, height and lot coverage from the zone’s table (Table 2‑3/2‑4/2‑7/2‑9) (§ 808.2.040, § 810.2.030, § 812.2.030)
- Prepare Site Plan Review materials when required (see Chapter 854.5) and include landscaping, parking, screening per Article 3 (link to Fresno County Design Review and Fresno County Parking)
- Check overlay, historic, Williamson Act, airport, and resource conservation constraints (Chapters 818.2, 808.2.030)
- If proposing housing, verify State ADU and density bonus interactions and that deed‑restriction or affordability rules (where applicable) are met (§ 824.3)
- Confirm any required environmental review (CEQA) and obtain required County or agency clearances before building permits (§ 800.1.030)
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Parcel-specific overlay restrictions (e.g., -M, -HB, historic) | Overlays can change height, setback, and design rules that materially affect project feasibility | Verify overlay mapping on the County Zone Map and read Chapter 818.2 for overlay standards; confirm with staff |
| Williamson Act contracts on agricultural parcels | Contracts impose minimum parcel sizes and limitations (homesite exceptions) that can block subdivisions | Check § 808.2.030 and County Interim Guidelines for contracted lands; verify contract status with County records |
| Nonconforming uses/structures | Existing lawful uses may be protected even if they don't meet new standards, but changes can trigger loss of protection | Consult Chapter 870.6 (Nonconforming Uses, Structures, and Parcels) and ask staff for parcel history |
| Interpretation of use tables for novel uses | The zone tables do not list every modern use (e.g., new tech uses) — an "unlisted use" may be subject to discretionary review | Use the Rules of Interpretation (§ 802.1.020) and request a Director's determination if ambiguous; be prepared to seek an Unclassified CUP (§ 842.5) |
| Parking and loading counts vs. site constraints | Off‑street parking standards (Chapter 828.3) can drive site layout and stormwater/landscaping needs | Confirm required parking calculation early and coordinate with Fresno County Parking and Chapter 826.3 landscaping requirements |
| State housing law conflicts (ADUs, density bonus) | State law may supersede or limit local discretion (e.g., ADU parking limits) | Check local density bonus rules (§ 824.3) and State ADU law; link to California ADU law and consult County planner |
Plain-English Summary
Fresno County's Zoning Ordinance describes what you can build on parcels in the County's unincorporated areas by mapping each parcel to a zone (AE, AL, R‑1, C‑4, M‑1, overlays, etc.), showing allowable uses in zone tables, and setting dimensional and operational standards (minimum parcel sizes, setbacks, heights, parking, screening). Start with the County Zone Map, read the specific zone's use table, and then apply the Article 3 development standards; for anything ambiguous or parcel-specific, verify with County staff and the relevant ordinance sections (§ 806.2.020, § 806.2.030) .

Frequently asked questions
What can I build in an AE zone in unincorporated Fresno County?
In unincorporated Fresno County the AE (Agricultural Exclusive) zone is intended for commercial agricultural uses; typical permitted uses are farming, accessory agricultural structures, and related operations listed in Table 2‑2. Minimum parcel sizes are set by the acreage designation (commonly 20 acres and up) and main-structure height is limited to 35 ft absent discretionary approvals (§ 808.2.010–040) .
How do I find the zoning for my unincorporated parcel?
Your starting point is the County’s official Zone Map (the Zone Map is adopted into the ordinance). Confirm the mapped zone and any overlays and then consult the corresponding Article 2 zone chapter and its tables to see allowable uses and required permits (§ 806.2.020–030) .
What are the setback and height rules for R‑1 and R‑R lots?
Setbacks and heights are established in the residential tables and general development standards; rural/estate residential variants commonly show 35 ft front setbacks and 20 ft side setbacks for primary structures, and height limits are indicated in the zone tables (see Table 2‑4 and § 822.3.100 for measurement/exception rules) (§ 810.2.030, § 822.3.100) .
Do I need Site Plan Review or design review in unincorporated Fresno County?
Many new developments or changes to structures require Site Plan Review under Chapter 854.5; the zone use tables mark uses that require “SPR”, and Article 3 standards (landscaping, parking, screening) typically must be shown in the site plan. Design review requirements depend on overlays, historic districts, or specific plan areas — check the zone table and Chapter 818.2 for overlays and Chapter 854.5 for the site plan process (§ 806.2.030, Chapter 854.5, Chapter 818.2) .
Are emergency shelters allowed in the unincorporated areas?
Yes—emergency shelters are specifically allowed in the C‑4 and C‑M zones but must comply with special development and operational standards (interior intake space, bed limits, parking ratios, security, and length-of-stay requirements), see § 834.4.130 for the full standards (§ 834.4.130) .
How do overlays like -M (Mountain) or -HB (Highway Beautification) affect my project?
Overlays modify or add development standards for parcels where they are mapped (height limits, landscaping, design controls). Always check Chapter 818.2 and the Zone Map to see if an overlay applies to your parcel and then follow the overlay property development standards set out in that chapter (§ 818.2.030–080) .
What happens if my parcel is under a Williamson Act contract?
Parcels subject to Williamson Act contracts have minimum parcel sizes and other restrictions (e.g., a 20‑acre guideline for prime farmland and homesite exceptions rules). See § 808.2.030 and County interim Williamson Act guidance; verify contract status with County records before subdividing or proposing non‑agricultural uses (§ 808.2.030) .
Where are parking requirements spelled out for a new commercial or multi‑family project?
Off‑street parking and loading standards are in Chapter 828.3. The commercial and multi‑family zone tables reference Chapter 828.3 and may specify special event or use‑specific parking rules; coordinate parking with landscaping and circulation shown in Site Plan Review materials (§ 812.2.030, Chapter 828.3) .
Can I build an ADU in an unincorporated Fresno County residential zone?
ADUs are governed by State law and local implementation. Fresno County implements local development standards for accessory units consistent with State ADU law; check local ADU provisions and State ADU rules (see County ordinance table for accessory/dwelling allowances and California ADU law) — where the ordinance does not conflict with State law, local development standards and Article 3 provisions apply (Verify with the jurisdiction) (§ 806.2.030, State ADU law) .
If a use is not listed in a zone table, what happens?
For uses not listed, the ordinance’s Rules of Interpretation (Article 1, § 802.1.020) guide whether a use is similar to a listed use; the County may require an Unclassified Conditional Use Permit or Director determination per Chapter 842.5 or 846.5 (§ 806.2.030, § 802.1.020) .
