Yuba County — Signage

Signage under the Yuba County local zoning and planning code, with the controlling citations.

Last reviewed: July 6, 2026

Overview

This page explains how the Yuba County Development Code regulates signs in the unincorporated areas of Yuba County. The rules live in Title XI, Development Code, specifically Chapter 11.27 — Signs, and apply across districts with special distinctions inside vs. outside the County’s Valley Growth Boundary (VGB) (§ 11.27.010–§ 11.27.020 ). Sign allowances also vary by district class (Residential, Commercial and Mixed-Use, Employment/Industrial, Rural/Resource), and must meet countywide measurement and general standards (§ 11.27.060–§ 11.27.080 ).

Most signs in unincorporated Yuba County are governed by Chapter 11.27 — Signs, with exact size/height tied to your district class and whether you’re inside or outside the Valley Growth Boundary (§ 11.27.090–§ 11.27.110 ).

Before getting into sign standards, confirm your base zoning and whether you’re inside the VGB on the County map and district tables in the Yuba County Zoning and Yuba County Land Use pages (§ 11.04.020 ).

How the ordinance is organized

Purpose and applicability: Chapter 11.27 applies countywide in unincorporated areas (§ 11.27.010–§ 11.27.020 ).
Exempt vs. prohibited signs: Detailed lists of what doesn’t need zoning clearance and what is outright prohibited (§ 11.27.030; § 11.27.040 ).
Measurement rules: How to calculate area (single- and double-faced), frontage, height, and clearance (§ 11.27.060 ).
General standards: Illumination, materials, visibility triangles, and right-of-way restrictions (§ 11.27.070 ).
Sign types: Baseline rules for freestanding, wall, projecting, awning, directional, menu/order boards, subdivision signs, and more (§ 11.27.080 ).
District-specific allowances: Outside VGB (§ 11.27.090), Residential (§ 11.27.100), and Nonresidential (§ 11.27.110) .
Programs and relief: Temporary promotional signs (§ 11.27.120), Planned Sign Permit Program (PSPP) for coordinated multi-tenant/area signs (§ 11.27.130), nonconforming signs (§ 11.27.140), maintenance and abatement (§ 11.27.150–§ 11.27.160), waivers/variances (§ 11.27.170) .

Where noted, the County also requires structural/electrical compliance with the most recent California Building Standards Code (§ 11.27.070(1) ).

Key definitions and common pitfalls

Exempt signs: Home occupations (one wall sign up to 4 sq ft), small “freedom of speech/political” signs (up to two, each ≤6 sq ft), real estate signs (size/height limits), many temporary information signs, and window signs up to 20% of the window area are typically exempt from zoning clearance if they meet the criteria (§ 11.27.030 ).
Window signs: Anything hung within 2 feet of a window counts as a window sign; in nonresidential districts window signs are capped at 20% of the window/transparent door area (§ 11.27.030; window-sign rule of proximity and 20% cap) .
Prohibited signs: Animated/flashy, inflatable, and most portable/A-frame signs; and roof signs that extend above the parapet or roofline (§ 11.27.040 ).
Measurement: Area of double-faced signs, lot/building frontage, height from ROW grade, and clearance are controlled by § 11.27.060 (helpful when computing totals for wall/freestanding signs) .
General limits: Keep signs out of rights-of-way without an encroachment permit; maintain intersection sight lines; illumination must be non-pulsating and shielded (§ 11.27.070 ).

District-by-district standards (unincorporated areas)

Yuba County organizes sign allowances by district class and VGB location. Use § 11.04.020 to identify your exact district: AE, AR, AI (Agricultural); RC, RR, RE (Rural Community/Residential Estate outside VGB); RE (within VGB), RS, RM, RH (Residential); GC, CMX, NMX, DC (Commercial & Mixed-Use); EC (Employment Center); IC, IG, IL (Industrial); PF, SE, SP/CP (Special Purpose) (§ 11.04.020 ).

Outside the Valley Growth Boundary — AE, AR, AI; RC, RR, RE (outside VGB); EX, TP, RPR

Purpose/uses: Agricultural operations, rural residential/communities, and natural resource areas (§ 11.04.020; references to A, Rural Community, NR classes) .
Freestanding signs: 1 per street frontage for individual uses (≤2 total), or more for rural commercial centers based on frontage; area ≤36 sq ft (individual) or ≤60 sq ft (rural commercial center); height ≤8 ft for monument; up to 15 ft pole sign if directly on a state highway or road posted 55 mph; setback ≥10 ft from ROW (§ 11.27.090 ).
Wall signs: 1 per tenant; area ≤1.5 sq ft per linear foot of building frontage, max 40 sq ft per tenant (§ 11.27.090 ).
Illumination: No internal illumination unless property is designated Rural Commercial or Public Facility (§ 11.27.090 ).
Where it applies: Parcels outside the VGB in these base districts (§ 11.04.020 ).

Residential districts — RE (within VGB), RS, RM, RH

Purpose/uses: Neighborhood residential; single-family through multifamily (§ 11.04.020 ).
Multi-unit/SRO sites (≥3 units): 1 freestanding or fence/sound wall sign ≤32 sq ft and ≤6 ft tall; plus 1 wall sign ≤40 sq ft; directory signs allowed at each primary entrance (§ 11.27.100 ).
Illumination: Internal illumination is not allowed in residential districts; only indirect lighting is permitted (§ 11.27.100 ).
Home occupations: 1 small wall sign (≤4 sq ft) is exempt if it meets criteria (§ 11.27.030 ).

Commercial & Mixed-Use districts — GC, CMX, NMX, DC (inside VGB)

Purpose/uses:
- GC supports a full range of commercial uses and some light manufacturing compatible with retail/service (§ 11.08 purposes; GC) .
- CMX enables high-density mixed retail/office with residential; pedestrian-oriented (§ 11.08; CMX) .
- NMX focuses on small, localized neighborhood services and mixed housing (§ 11.08; NMX) .
- DC aims for a small-town downtown core with walkable design (§ 11.08; DC) .
Freestanding signs (nonresidential uses): Individual sites may have 1, with a second if multiple frontages, freeway adjacency, or long frontage with multiple driveways; building complexes get additional signs per frontage thresholds (§ 11.27.110 ).
- Heights: DC and neighborhood-service uses in R districts: 8 ft; all other nonresidential districts: 20 ft; plus one sign may reach 25 ft when oriented to a freeway or state highway (§ 11.27.110 ).
- Areas: DC/neighborhood-service uses: 36 sq ft; other nonresidential: 150 sq ft (bases excluded) (§ 11.27.110 ).
Wall signs: Individual uses may have up to 2 (facing entries/streets/parking); complexes: major tenants unlimited, pad buildings get 3 (single tenant) or 2/tenant (multi-tenant), others get 1 (2 on a corner); total wall-sign area ≤1.5 sq ft/lf building frontage, max 200 sq ft per use (major tenants in complexes up to 300 sq ft); length ≤70% of tenant/building façade (§ 11.27.110 ).
Projecting/Awning: 1 projecting sign allowed in DC and NMX and in building complexes; up to 3 awning signs (one per awning) (§ 11.27.110 ).
Directional signs: On-site directional signs (number, ≤4 sq ft area, ≤4 ft tall, safe locations); off-site directional signs only for nonresidential uses outside VGB with specific criteria (§ 11.27.110; off-site directional criteria) .
Programmable electronic signs: Allowed for specific uses (service stations for fuel prices, hotels/motels for vacancies/rates, theaters/churches for events, time/temperature, government info); must meet freestanding/wall standards (§ 11.27.110; programmable signs) .

Employment Center and Industrial districts — EC; IC, IG, IL

Purpose/uses: Employment campus and industrial operations (§ 11.04.020; § 11.09.030 tables) .
Sign allowances: Treated as “other nonresidential districts” under § 11.27.110 (e.g., freestanding height up to 20 ft, one may be 25 ft if freeway-oriented; area up to 150 sq ft; wall-sign area and counts per § 11.27.110) .

Special Purpose districts — PF, SE, SP/CP

Purpose/uses: Public facilities, sports/entertainment, and plan areas (§ 11.04.020) .
Sign allowances: Governed by § 11.27.110 for nonresidential uses (same freestanding/wall/illumination rules described above) .

Special sign topics you’ll likely use

Temporary promotional signs: Up to two per business; must be durable, unlit, and without moving parts; maximum total temporary sign area scales by building frontage (≤60/80/120 sq ft); location limited to frontages and may not extend above roof/parapet; additional temporary signs may be waived for a short period by the Zoning Administrator (§ 11.27.120 ).
Subdivision signs: Off-premises subdivision signs have strict content, spacing, erection/removal rules; on-site entry signs limited in number (up to four per entrance), area (freestanding/wall ≤32 sq ft; logo ≤4 sq ft), and height (≤6 ft) (§ 11.27.080(6)–(7) ).
Service station signs: One freestanding fuel-price sign up to 100 sq ft and 15 ft high; base must match building materials; programmable display permitted for fuel pricing only (static; change no more than once per 12 hours); combined area for wall+awning signs capped at 200 sq ft; up to four canopy (awning) signs; pump/under-canopy price signs are allowed (§ 11.27.110 service-station standards; § 11.27.120 header context) .
Planned Sign Permit Program (PSPP): Required for certain off-site subdivision, plan-area, or community/regional branding signs; can allow additional area or deviations if findings are made; reviewed by the Development Review Committee or other decision-making body if tied to other approvals (§ 11.27.130 ).
Nonconforming and illegal signs: Certain existing pole signs in commercial districts may continue (copy change only); damaged beyond 50% generally must comply if rebuilt; abandonment triggers removal; County can abate illegal/unsafe signs (§ 11.27.140–§ 11.27.160 ).
Relief: A waiver or variance can be granted where strict adherence is impractical or causes undue hardship (§ 11.27.170). See Yuba County Variances and Exceptions for process context (§ 11.27.170 ).

Also note cross-overs:

Visibility triangles at driveways/intersections are enforced via General Site Regulations; coordinate with Yuba County Development Standards (§ 11.27.070; § 11.19.130 reference) .
No sign may encroach into the County right-of-way without an encroachment permit; if you need encroachment, expect coordination with Public Works (§ 11.27.070(3) ).
Signs along State highways must comply with state/federal standards (§ 11.27.070(2) ). Overlays (e.g., Airport Environs, Floodplain) may add constraints—see Yuba County Overlay Districts.

Quick limits that decide most projects

Checklist

Identify if the parcel is inside or outside the VGB and confirm the base district on the map and tables in the Yuba County Zoning pages (§ 11.04.020 ).
Verify any applicable overlays (e.g., AP, FP) that may add constraints; see Yuba County Overlay Districts.
Determine sign type(s) and compute allowable area/height/length using the rules of measurement (§ 11.27.060; § 11.27.080 ).
Check general standards: ROW encroachment, sight distance, illumination, materials (§ 11.27.070 ).
Confirm if the sign is exempt, prohibited, or requires zoning clearance (and whether a PSPP is needed for multi-tenant/area branding) (§ 11.27.030–§ 11.27.040; § 11.27.130 ).
If along a State highway, ensure no conflict with state/federal highway sign rules (§ 11.27.070(2) ).
Coordinate with Yuba County Design Review if your broader project triggers design review alongside signs.
Confirm parking/driveway layout supports safe directional signage; see Yuba County Parking (§ 11.27.110; directional sign limits) .
Maintain the sign and remove any illegal/nonconforming conditions if triggered by change in use/abandonment (§ 11.27.140–§ 11.27.160 ).

Risks & Ambiguities

Issue	Why it matters	What to verify
Freeway-oriented height increase (to 25 ft)	Only one freestanding sign may increase height and must be oriented to the freeway/highway (§ 11.27.110)	Site plan showing orientation and freeway adjacency; confirm “one sign” limit applies.
Defining a “rural commercial center”	Outside VGB allowances scale differently for rural centers vs. individual uses (§ 11.27.090)	Parcel configurations, shared access/parking across parcels; Planning staff interpretation.
Window sign percentage	Over-counting or under-counting window area can cause violations (§ 11.27.030)	Measure transparent frontage per façade; remember anything within 2 ft of a window counts (§ 11.27.030) .
Programmable electronic signs	Allowed only for enumerated uses; content/static limits apply (§ 11.27.110)	Confirm your use category fits; ensure static display and frequency-of-change rules (e.g., fuel prices).
Nonconforming pole signs	Some may continue but can’t be altered (beyond copy) (§ 11.27.140)	Status evidence (permits/dates), extent of damage if repaired, and any change-of-use triggers.
ROW encroachments	Signs in/over ROW require encroachment permit (§ 11.27.070(3))	Exact property line/ROW surveys; Public Works encroachment approval.

Plain-English Summary

In unincorporated Yuba County, your sign size and height depend first on whether you’re inside the Valley Growth Boundary and which district you’re in. Most businesses inside the VGB get wall signs up to 1.5 sq ft per foot of storefront (typically capped at 200 sq ft) and one or two freestanding signs up to 20 ft tall (25 ft if freeway‑oriented), while rural sites outside the VGB are generally limited to smaller, lower signs with tighter illumination rules (§ 11.27.090–§ 11.27.110 ). Temporary banners are allowed with limits, and certain signs are exempt or prohibited; everything must meet visibility, ROW, and lighting rules (§ 11.27.030–§ 11.27.040; § 11.27.070 ).

Frequently asked questions

Are portable A-frame/sandwich board signs allowed in unincorporated Yuba County?

Generally no. Portable signs (A-frames, T-frames, sandwich boards) are prohibited unless expressly provided elsewhere in Chapter 11.27 (e.g., certain temporary scenarios) (§ 11.27.040) .

How big can my business’s freestanding sign be next to a State highway?

In nonresidential districts, one of your allowed freestanding signs may increase to a maximum height of 25 ft if it is oriented to the freeway or state highway (§ 11.27.110) . Otherwise, typical limits are 20 ft (most nonresidential) or 8 ft (DC/neighborhood-service contexts).

What are the limits for window signs at my store?

Window signs in nonresidential districts are limited to 20% of the window/transparent door area, and anything installed within 2 ft of a window counts toward that total (§ 11.27.030) .

Can I use an electronic message center (LED) for general advertising?

Programmable electronic signs are limited to specific uses: fuel prices at service stations, hotel/motel rates/vacancy, time/temperature, government info, and event notices at theaters/churches and similar venues. They must also meet the freestanding/wall sign standards (§ 11.27.110) .

What are the temporary banner rules for grand openings?

Up to two temporary promotional signs are allowed per business at a time; they must be durable, unlit, have no moving parts, and total sign area is capped by storefront frontage (≤60/80/120 sq ft). Placement is limited to fronting areas and cannot exceed the roof/parapet (§ 11.27.120) .

I’m in a rural area outside the VGB. What freestanding sign can I have?

Individual uses outside the VGB get one freestanding sign per frontage (max two total), up to 36 sq ft and 8 ft tall, with a 10 ft setback from the ROW. If directly on a state highway or a 55 mph road, a pole sign up to 15 ft is allowed (§ 11.27.090) .

Do subdivision entry monuments have specific limits?

Yes. At each entrance, up to four on-site signs are allowed within type caps (freestanding/wall ≤32 sq ft; logo ≤4 sq ft; max height 6 ft), with specific location setbacks and rules. Off-site subdivision signs have separate content/spacing/timing rules (§ 11.27.080(6)–(7)) .

When do I need a Planned Sign Permit Program?

A PSPP is required for certain off-site subdivision signs not meeting standards, plan-area/community signs, or modifications to an existing PSPP. It can approve extra area or deviations if findings are made (§ 11.27.130) .

My old pole sign is legal but nonconforming—can I change its structure?

Generally no. In commercial districts, legally established pole signs may continue but cannot be modified beyond copy changes. Extensive damage or abandonment can trigger removal or full Code compliance (§ 11.27.140) .

Do signs have to meet building and electrical codes?

Yes. All signs must comply with the County’s adopted structural and electrical provisions of the California codes (permit requirements may apply separately). Also, no encroachment into the ROW without Public Works approval (§ 11.27.070) .
