San Jacinto — Signage

Signage under the San Jacinto local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

San Jacinto regulates signs in Chapter 17.335 of the Development Code to balance identification needs with public safety and community character (§ 17.335.010) . The sign rules apply citywide to private-property signs (with some exemptions) and set permit, measurement, illumination, temporary-sign, and programmatic (comprehensive sign program) standards (§ 17.335.020; § 17.335.130) . Because signs can affect circulation and land use, check applicable rules for parking, development standards, and design review when you plan a new sign (see related links below).

District-by-district sign summary

The Development Code establishes specific zones; sign rules are applied by zone groups. Below are the sign rules organized by the code's zoning groups. All zone names and symbols come from § 17.200.020 (Zones Established) . Where a specific table governs a zone, that table controls unless a specific sign-type standard says otherwise.

Residential zones (RE, RR, RL, RM, RH, RVH)

Purpose / where it applies: Residential zones are RE, RR, RL, RM, RH, RVH and are listed in Table 2‑1 (§ 17.200.020) .
Typical permitted sign uses: small identification/nameplates, residential community entry signs, and limited freestanding or wall signs for multi-family developments; commercial signage for home occupations and cottage businesses is restricted and cross-referenced to the broader sign chapter (see § 17.430.140 for cottage-business signage exceptions) .
Key dimensional standards (residential): generally small—nameplates up to 2–4 sq ft for single-family, multi-family identification and community entrance signs up to 12–40 sq ft depending on type and number; max height typically 6 ft for freestanding identification signs in residential contexts (see Table 3‑11 and related notes) (§ 17.335.070, Table 3‑11) .
How applied: Sign permit required except exempt signs; Director may allow modest increases where residential character will not be harmed (§ 17.335.070) .

Commercial / Office / Industrial zones (CG, CN, CR, BP, OP, IL, IH)

Purpose / where it applies: Commercial and industrial zones are CG, CN, CR, BP, OP, IL, IH and are listed in Table 2‑1 (§ 17.200.020) .
Typical permitted sign uses: wall/tenant signs, canopy/awning signs, freestanding signs (monument or pylon), directory signs, window signs, and changeable-copy signs subject to limits. Billboards (off‑site advertising) are prohibited (see Billboard policy) .
Key dimensional standards (commercial): permitted freestanding sign area is typically calculated as 1 sq. ft. per linear foot of primary building frontage for the primary sign; secondary signs max 50% of the primary sign area; monument signs typically limited to 7 ft height; pylon signs up to 25 ft height; wall signs often limited to 32 sq ft or 1 sq. ft. per linear foot of tenant frontage (whichever is greater), and a per‑façade cap of 150 sq ft total for primary + accessory wall signs — see Table 3‑12 and § 17.335.080 for specific types and counts .
How applied: Multi‑tenant centers with extensive frontage or many tenants must submit a Comprehensive Sign Program (§ 17.335.130) and the Director is the review authority for that program .

Mixed‑use zones (MU, MU‑E, DV)

Purpose / where it applies: MU, MU‑E, DV (Downtown Village) are mixed-use zones in Table 2‑1 (§ 17.200.020) .
Typical permitted sign uses: similar to commercial but with additional pedestrian-scaled constraints (e.g., blade signs, smaller projecting signs, multiple smaller wall signs oriented to sidewalks) and special allowances for upper-story signs only through a comprehensive sign program (§ 17.335.130) .
Key dimensional standards: pedestrian-oriented limits — signage on upper stories or above the second story generally requires a comprehensive sign program; wall and blade sign counts follow Table 3‑12 maximums unless modified by a program (§ 17.335.130; Table 3‑12) .

Special Purpose zones (OSG, OSR, PI, SP)

Purpose / where it applies: OSG, OSR, PI, SP (open space, public institutional, specific plan) (§ 17.200.020) .
Typical permitted sign uses: site identity and directional signs, interpretive signs in parks/open spaces; in some OSG/OSR areas the code requires a comprehensive sign program for signs that are not straightforward (see § 17.335.130) .
Key dimensional standards: treated on a case-by-case basis; many Open Space signs must go through a comprehensive program when larger or when signs are to be placed in rights‑of‑way (§ 17.335.130) .

Overlay/Combining zones (examples)

The City applies suffix overlay zones (e.g., -H6, -RAAB) on top of base zones; sign rules of the base zone apply unless the overlay adds requirements (§ 17.235.020) . For overlay areas that are part of a specific plan or special study, a comprehensive sign program or design review may be required (verify on a parcel‑by‑parcel basis) .

Checklist (what an applicant must provide / satisfy)

Confirm the base zone for the parcel (RE/RL/RM/RH/RVH, CG/CN/CR, MU, OSG/PI, etc.) and applicable overlays (§ 17.200.020) .
Determine whether a sign permit is required (virtually always) and apply per § 17.335.120 (procedures/fees/filing) — include owner consent where sign is on another property (§ 17.335.020; off‑site sign rules) .
Submit a scaled sign location/size plan showing: sign area calculation, sign height (measured per code), mounting details, materials, illumination method, and landscaping/clearance (if freestanding) (§ 17.335.040; § 17.335.080) .
If placing signage in a public right‑of‑way or on City property, obtain an Encroachment Permit from City Engineer (city requires encroachment for right‑of‑way signs) (§ 17.335.090 / related permit notes) .
For illuminated signs or EV charging signage, be prepared to provide a photometric study and to meet illumination controls; the Director may require dimming after review (§ 17.335.080; § 17.335.090.I) .
If the project is a multi‑tenant center, long frontage, or proposes signs above 2nd floor, prepare a Comprehensive Sign Program (drawings, findings) per § 17.335.130 .
Pay attention to maintenance obligations: removed signs must remove supports and restore building surfaces; illuminated signs subject to 30‑day review window (§ 17.335.140; § 17.335.080.G) .
Verify whether design review or a discretionary permit is required because sign approval may be tied to a site plan and design review, conditional use permit, or variance (Director/Commission authority varies) — check Design Review and Variances and Exceptions pages and Chapters 17.600–17.660 for review authority and appeals .

Risks & Ambiguities

Issue	Why it matters	What to verify
Mixed‑use assignment of sign rights	The Code instructs that mixed‑use buildings treat residential and nonresidential uses differently for sign rights; this can affect the number/area of tenant signs.	Verify whether your specific tenant is treated as “residential” or “nonresidential” for signage under § 17.335.030.E and Table 3‑12; parcel‑specific interpretation may apply.
Sign area & face measurement	Several special rules (double‑faced signs, three‑dimensional objects, frames) change how area is calculated.	Confirm the Director’s preferred measurement approach and the sign face(s) counted (see measurement rules in § 17.335.040 and Figure examples). Verify with the Department.
Billboard prohibition vs. legacy signs	Existing legal billboards may be “grandfathered” while new ones are prohibited.	Check whether a structure is an existing lawful billboard or requires removal under § 17.335.030.F; verify property history.
Illumination nuisance complaints	Director may dim or require changes after installation if lights create a nuisance.	Ask whether a photometric plan will be required at application stage; verify the Director’s recent practice. See illumination rules § 17.335.080.
Signs in rights‑of‑way/encroachment	Signs on or projecting over rights‑of‑way need an encroachment permit.	For any sign proposed on City ROW, confirm Encroachment Permit process with City Engineer per sign chapter and public works procedures.
Variances / minor variance for sign exceptions	Code allows minor variances (including for signs) but with limits (e.g., 15% for sign rules).	If your sign needs larger deviations, plan for a minor variance/variance under Chapter 17.650; confirm which review body will hear it.

Plain‑English summary

San Jacinto’s sign rules (Chapter 17.335) set size, height, placement, lighting, and temporary‑sign limits by zone: small, low signs for homes; larger, structured allowances for commercial centers; and a required comprehensive sign program for big, multi‑tenant or long‑frontage projects. You generally need a sign permit, must follow the measurement and illumination rules, and may have to apply for a variance or a comprehensive sign program for exceptions (§ 17.335.010–.140) .

Frequently asked questions

What sign permit do I need for a storefront in San Jacinto?

Most storefront signs require a sign permit under the Development Code; the permit procedure and required materials are governed by § 17.335.120 (procedures) and the sign rules in § 17.335.070–.080. Prepare scaled plans showing sign area, height, mounting, materials, and illumination details; multi‑tenant or largefrontage projects may instead require a Comprehensive Sign Program per § 17.335.130 .

How big can my freestanding commercial sign be in San Jacinto?

Commercial freestanding primary signs are typically sized at 1 sq. ft. per linear foot of primary building frontage; secondary signs may be up to 50% of the primary sign area. Height caps differ by sign type (monument ≈ 7 ft, pylon ≈ 25 ft) — see Table 3‑12 and § 17.335.080 for the exact calculations and exceptions .

Are billboards allowed in San Jacinto?

No — the City’s billboard policy prohibits new billboards (off‑site advertising signs) except for pre‑existing lawful billboards or those with a valid permit existing before adoption of the policy; see § 17.335.030.F for the billboard prohibition and policy statement .

Can I have an internally illuminated sign with a translucent background?

Internal illumination is allowed only if the sign background is opaque and only the lettering/trademark/logo appears illuminated; illumination must not create nuisance or safety hazards and may be subject to post‑installation dimming by the Director (§ 17.335.080 — illuminated signs) .

Do temporary banners and event signs need permits and how long can they stay up?

Yes — temporary event/promo signs usually require a temporary sign permit and are limited: no more than 45 consecutive days for a promotional posting and 180 total days per calendar year for special‑event signs; banners have size and frequency limits under § 17.335.100 .

When is a Comprehensive Sign Program required?

A Comprehensive Sign Program is required for projects with four or more tenant spaces, four or more nonexempt signs for a single tenant, signs proposed above the second story, projects with over 300 linear feet of street frontage, or substantial remodels of existing multi‑tenant developments; see § 17.335.130 for applicability and findings the Director must make .

How is sign area measured in San Jacinto?

Sign area measurement rules are in the sign chapter: sign area generally includes the display surface and frame (but not support poles unless they form part of the display), double‑faced signs are counted once if faces are ≤2 feet apart, and three‑dimensional objects use their maximum projection upon a vertical plane — see measurement rules and figures in § 17.335.040 and § 17.335.080 .

Can I put directional signs off site for my business (off‑site directional signs)?

Off‑site directional signs are permitted under specific rules (they must direct to lawful uses within the City, are typically limited to one per establishment unless multiple entrances justify more, and must meet design/location rules tied to the zone where placed). Off‑site directional standards (attachment to existing freestanding signs, cumulative area limits, and Director approval of design) are in § 17.335.090.I (and related subsections) — permission from the owner where the sign will be located is required .

If my project is in a Historic or Special overlay, do sign rules change?

Overlay zones and combining zones append requirements to the base zone; the base sign rules apply unless an overlay or specific plan explicitly modifies them. Check the overlay text that applies to your parcel (overlays are listed in § 17.235.020 and in Table 2‑1) and be prepared for design review or a comprehensive program where overlays emphasize character protection .
