Chowchilla — Signage

Last reviewed: July 1, 2026

Overview

Chowchilla regulates signs in Chapter 18.56 — Signs and Outdoor Advertising Structures of the zoning code; the chapter applies citywide and is intended to balance free expression with neighborhood character, traffic safety, and aesthetics (§ 18.56.010, § 18.56.020) . This reference summarizes what the ordinance actually requires by zoning district (residential, commercial, industrial, mixed‑use, public facilities, and open space), explains measurement and illumination rules, identifies exemptions and prohibited signs, and points out where applicants must look up parcel‑specific exceptions (airport overlay, State Highway 99 corridor). See the city’s rules on development standards for how sign setbacks and site layout interact with other dimensional rules and consult the California Building Standards Code for electrical and structural permitting of illuminated or engineered signs.

Chapter highlights: noncommercial speech cannot be disadvantaged (subject to certain limits) (§ 18.56.030) ; a set of commonly exempt signs exists (§ 18.56.040) ; prohibited signs are listed (§ 18.56.050) ; and a zone-by-zone table sets numeric limits (Table 18.56.090(A)/(B)) that control how many and how large permanent and temporary signs can be (Table 18.56.090) .

Citywide rules that apply to all districts (summary)

• Purpose and scope: Chapter 18.56 applies to private on‑site signs throughout Chowchilla (§ 18.56.010, § 18.56.020) .
• Permit vs. exempt: Many small residential nameplates, vehicle signs, holiday decorations, interior signs not visible from the street, and certain temporary signs are exempt from sign permits (§ 18.56.040) .
• Prohibited signs: signs that mimic traffic devices, signs obstructing ingress/egress, and off‑site outdoor advertising on properties other than the advertised business are prohibited (§ 18.56.050) .
• Design & measurement: design principles (compatibility, legibility, materials), and rules for measuring sign face area and lot/frontage are in § 18.56.070 and § 18.56.080 .
• Lighting & electrical: illumination that causes glare to residences is controlled, internally illuminated signs must have non‑gloss backgrounds, shielding and lamp restrictions apply (mercury vapor prohibited); concealed electrical systems are required (lighting rules and § 18.56.200) .
• Master sign programs: required for sites with more than three commercial establishments; approved programs are enforced and do not waive individual sign permits (§ 18.56.210) .
• Enforcement: unlawful signs (erected without required permits or after effective date) are a public nuisance and subject to abatement under the code (§ 18.56.290) .

Note: structural or electrical work for signs that require engineered supports or wiring still needs building permits and must comply with the California Building Standards Code (verify with the building department) (exempt sign note in § 18.56.040) .

District-by-district sign rules (purpose, typical uses, key numeric standards, where it applies)

The numeric limits below come from Table 18.56.090(A)/(B); always confirm with the code for edge cases (Table 18.56.090) .

R-L (Rural / Low Density Residential)

• Purpose & typical uses: single‑family dwellings and low‑density residential uses (see R‑L chapter for full purpose). Signs in R‑L are subject to Chapter 18.56 (18.10.180) .
• Key sign limits: 1 sign per residence, 4 sq. ft. max per permanent building sign, placement max 8 ft high; freestanding signs are not allowed by right (Table 18.56.090(A)) .
• Temporary: limited (see Table 18.56.090(B) for temporary allowances) (Table 18.56.090(B)) .
• Where it applies: all parcels zoned R‑L (see zoning map) — see Chowchilla Zoning.

R-M (Medium Density Residential)

• Purpose & typical uses: multi‑family and medium density residential developments; signs in R‑M must follow Chapter 18.56 (18.12.180) .
• Key sign limits: for sites with 4 or fewer residences, 1 sign per site, 4 sq. ft. max (same as R‑L); where 5+ residences or non‑residential uses are present: 1 sign per street frontage, 32 sq. ft. max per building sign; freestanding signs allowed with 20 sq. ft. max and 6 ft height max (external illumination only where allowed) (Table 18.56.090(A)) .

R-MH (Mobile Home)

• Purpose & typical uses: mobile home parks and similar; treated like R‑M for signage. Key limits mirror R‑M: building sign area caps and freestanding allowances per Table 18.56.090 .

R-H (High Density Residential)

• Purpose & typical uses: higher density housing (apartments, senior housing). Signs must follow Chapter 18.56; in many R‑H situations the code permits 1 sign per street frontage, 30–32 sq. ft. per sign depending on circumstances; freestanding signs allowed under limits in Table 18.56.090 (18.16.170) .

C-N, C-S, C-H (Neighborhood, Service, Highway Commercial)

• Purpose & typical uses: commercial establishments — retail, services, automobile‑oriented uses.
• Key sign limits (commercial core): building signs are limited by frontage: primary frontage = 2 sq. ft. per 1 lineal ft. up to a maximum of 350 sq. ft. (50 sq. ft. minimum regardless of frontage); secondary frontage = 1 sq. ft. per 1 lineal ft. up to 200 sq. ft. (30 sq. ft. minimum). Freestanding signs: 1 sign per establishment, 60 sq. ft. max sign face, height 10 ft if set back <10 ft; 20 ft max if set back ≥10 ft; signs over 20 ft require a conditional use permit (Table 18.56.090(A)) .
• Highway exceptions: parcels in C‑N/C‑S/C‑H/MX adjacent to State Highway 99 may qualify for additional highway‑oriented signs under § 18.56.094; location criteria are strict (east of UPRR tracks, west of S. Fig Tree Blvd, south of Ash Slough, north of Berenda Slough) (§ 18.56.094) .

MX (Mixed Use) and MX‑D (Mixed‑Use Downtown)

• Purpose & typical uses: combinations of retail, office, and housing; MX signs follow the commercial rules above.
• MX‑D (downtown form) has more restrictive limits: primary frontage = 2 sq. ft. per 1 lineal ft. up to 60 sq. ft., secondary = 1 sq. ft. per ft. up to 30 sq. ft., and freestanding signs are not allowed in MX‑D (Table 18.56.090(A)) .
• Downtown design review expectations: signs should meet the city's design guidance and may be subject to design review and master sign program requirements (§ 18.56.070, § 18.56.210) .

O (Office)

• Purpose & typical uses: professional offices and similar uses.
• Key sign limits: 1 sign per street frontage, 30 sq. ft. max building sign; freestanding signs: 1 sign per site, 20 sq. ft. max, 6 ft height; external illumination only (Table 18.56.090(A)) .

I-L and I-H (Light / Heavy Industrial)

• Purpose & typical uses: industrial, manufacturing, warehousing; signs in these zones are governed by Chapter 18.56 (18.34.140) .
• Key sign limits: building signs — there is no numeric limit to the number of signs per establishment; allowed sign area is 1 sq. ft. per lineal ft. of property line adjoining a street, or 100 sq. ft. per acre of site in use, whichever is greater, up to a maximum of 600 sq. ft. Freestanding: 1 sign per frontage, 60 sq. ft. max face, 20 ft height allowed by right (over 20 ft needs CUP) (Table 18.56.090(A)) .

PF (Public Facilities)

• Purpose & typical uses: public buildings, parks, schools; signs are subject to Chapter 18.56 with typically modest size limits.
• Key sign limits: 1 sign per street frontage, 32 sq. ft. max building sign; freestanding: up to 4 per site, 32 cumulative sq. ft. with the first sign 5 ft max height and other signs 2 ft max (Table 18.56.090(A)) .
• PF purpose and where to look: see § 18.36.010 for PF zone purpose and application (§ 18.36.010) .

OS (Open Space)

• Purpose & typical uses: parks, open areas. Signs in OS follow Chapter 18.56, but signs placed by local/state/federal agencies on their own public property are exempt from Chapter 18.56 (§ 18.38.150) .

Practical guidance & interpretation notes

• Always calculate sign area using the code’s measurement rules (single continuous rectangle enclosing all elements); supporting bases that carry no copy are excluded from area calculations (§ 18.56.080) .
• Noncommercial messages can replace commercial copy on a legally established sign without extra review, but that substitution does not increase the total allowed sign area (§ 18.56.030) .
• If a site contains more than three commercial tenants, a master sign program must be submitted/approved; the director reviews minor amendments; the planning commission approves master sign programs with project CUPs (§ 18.56.210) .
• Illumination adjacent to residences: expect additional controls (rheostat, shielding, opaque matte backgrounds for internal illumination). Mercury vapor lamps are expressly prohibited (lighting standards) .
• Airport overlay and FAA rules: proposed freestanding sign heights must comply with the Madera County Airport Land Use Compatibility Plan and FAA where applicable — signs above 20 ft often require higher level review (Table notes and § 18.40.020) .
• Highway 99 corridor: special highway‑oriented sign allowances are available only in narrowly defined parcels — confirm parcel location before assuming larger sign allowances (§ 18.56.094) .

Link to related site processes: if sign changes affect parking layout or site circulation, coordinate with parking and with general development standards. Signs in historic areas may also intersect with historic preservation review; freestanding landscaping around sign bases should follow landscaping and screening requirements.

Checklist — what an applicant must satisfy

• Confirm the parcel ZONE and applicable overlay(s) (e.g., Airport Overlay) and apply the corresponding Table 18.56.090 limits (§ 18.56.020; Table 18.56.090) .
• Measure sign area per § 18.56.080 rules and verify number of permitted signs (§ 18.56.080; Table 18.56.090) .
• Determine if the sign is exempt (e.g., small nameplate) (§ 18.56.040) .
• If >3 commercial tenants, prepare a master sign program (director review / planning commission if part of CUP) (§ 18.56.210) .
• For illuminated signs, show shielding, rheostat control (if residential adjacency), and lamp type (no mercury vapor) (lighting rules) .
• If freestanding and taller than 20 ft or located near the airport, confirm FAA and ALUCP constraints (Table 18.56.090 notes; § 18.40.020) .
• Pull building/electrical permits for signs with engineered supports or electrical connections (coordinate with the building department and the California Building Standards Code).
• Submit drawings consistent with sign design principles (materials, legibility, scale) and with any required site plan or design review (§ 18.56.070) .

Plain-English Summary

Chowchilla’s sign code (Chapter 18.56) sets numeric caps on sign size and number by zone, exempts very small or certain public signs, controls illumination to avoid glare, requires master sign programs for multi‑tenant developments, and reserves large freeway‑oriented exceptions to specific State Highway 99 parcels — always measure sign area per the code and get building/electrical permits when supports or wiring are required (§ 18.56.010–§ 18.56.210; Table 18.56.090) .
