Hermosa Beach — Signage

Q: How do I calculate allowable sign area for a storefront in Hermosa Beach?

Permanent sign area is generally computed as 2 sq ft per foot of lineal building frontage , with a minimum of 20 sq ft ; double‑faced signs count as one side plus half the other. See § 17.50.120(D) for the formula and applying secondary frontages.

Q: Are illuminated signs allowed along the open‑space edge or in parks?

In OS / OS‑1 zones, signs should be constructed of natural‑appearing materials and shall not be illuminated except where necessary for safety; importantly, all new signs in OS zones require Planning Commission approval under § 17.50.110 .

Overview

This page explains what the Hermosa Beach municipal zoning code requires for signs (Chapter 17.50 of Title 17 Zoning) and translates the rules into practical, parcel-level guidance. It covers permit triggers, allowed sign types and sizes by district, maintenance, nonconforming signs, portable A‑frame rules, and discretionary review paths. Wherever the code ties into other topics (construction standards, design review, parking, ADUs, overlays), the first natural mention of those topics is linked to the corresponding GoCodebook page.

How to read citations on this page

Each requirement below is grounded to the Hermosa Beach code by the code paragraph (for example § 17.50.040) and the uploaded municipal-code file preview where that paragraph appears. The file citation marker for each quoted section is provided immediately after the § reference (for example ).

District-by-district signage rules (what differs by zone)

Note: the controlling sign rules live in Chapter 17.50 Signs of Title 17 Zoning. The code defines terms and the districts in Title 17; specific sign rules are mostly in § 17.50.040 – § 17.50.220 and district subsections. See the municipal code table of contents under Title 17 for zone names and purposes.

All district references below are bolded (e.g., C-2) and the controlling code citations are given.

Residential zones — R-1, R-1A, R-2, R-2B, R-3 (single- and multi-family)

Purpose / typical intent: residential identification, small real‑estate or tenant information signs; the code treats residential sign rules conservatively.
Key rule: Residential and multi‑family dwellings use the allowances described in the residential sign section; multi‑family standards are referenced to § 17.50.090 (multiple‑family residential) and related definitions. § 17.50.090 (residential sign allowances) is referenced in the code provisions for R zones.
Practical: expect small building‑identification signs, real‑estate signs, and limited temporary signs (see § 17.50.210 for temporary sign limits).
Verify: parcel use (single vs. multi‑family) because allowable sign types and counts change by residential use; verify with the planner.

R-P (Residential‑Professional) — § 17.50.100

Purpose / typical intent: mixed residential/professional buildings (medical, small offices).
Key rule: Signs for residences in R‑P follow the residential rules in § 17.50.090; signs for businesses in R‑P follow the C‑1 (neighborhood commercial) rules per § 17.50.100.
Practical: business tenants in R‑P should prepare signage consistent with C‑1 allowances (one wall sign, awning signs, etc.); see § 17.50.120 for the C‑1 specifics.

OS and OS‑1 (Open Space / Restricted Open Space) — § 17.50.110

Purpose / typical intent: parks, beaches, natural open space.
Key rule: All new signs in OS/OS‑1 require Planning Commission approval; limited to wall or ground signs, natural materials, non‑illuminated except for safety reasons per § 17.50.110.
Practical: expect discretionary review (planning commission) and stricter material/illumination limitations.

C‑1 (Neighborhood Commercial) — § 17.50.120

Purpose / typical intent: pedestrian‑oriented neighborhood commercial corridors.
Permitted sign types: one wall sign, one awning sign, one ground sign, one projecting sign (business identification only), window signs, murals (murals require commission approval). § 17.50.120(A–B).
Size & placement: total permanent sign area is governed generally by the formula in the code (see Allowable Sign Area below), signs above the first story are limited (max 28 ft above street grade) and pole signs are not permitted in C‑1. § 17.50.120(D–G).
Practical: C‑1 focuses on pedestrian scale and limits vertical/pole signs.

C‑2 (Restricted Commercial / Downtown) — § 17.50.130

Purpose / typical intent: the downtown, entertainment and pedestrian core (Hermosa’s beach/downtown).
Permitted signs per site: business signs, building identification signs, one real‑estate sign, one construction sign, temporary signs, commodity identification (with percent caps), portable A‑frame signs (subject to § 17.50.220) and other enumerated types. § 17.50.130(A).
Styles allowed per business: one wall sign, one ground sign per site, one awning sign, projecting sign (business ID), marquee sign, window signs, banners, murals (commission may waive area/height limits). § 17.50.130(B).
Height & coverage: pole signs not permitted in C‑1; C‑2 downtown rules emphasize pedestrian scale and include limitations on percent of wall coverage (no more than 25% of the wall). § 17.50.130 & § 17.50.120(D‑4).
Practical: downtown businesses should design a single coordinated sign program (see sign plan requirement under § 17.50.040(C)).

C‑3 (General & Highway Commercial) — § 17.50.140

Purpose / typical intent: automobile‑oriented strip commercial (higher visibility).
Permitted: broader sign types consistent with auto orientation; general rules for allowable area and height vary from C‑1/C‑2 — consult § 17.50.140 for the C‑3 specifics and the general limitations.
Practical: C‑3 can support larger sign area calculations but still subject to the city’s area formula and other limits.

M‑1 (Light Manufacturing) and Industrial/Other Zones

The code ties some M‑zone sign requirements to the C‑zone rules or refers applicants to § 17.50.140; check the specific M‑zone subsection and § 17.50.140 for consistency. Not all M‑zone special cases are repeated in the signs chapter (verify with the planner).

Universal/General sign standards (applies across districts)

Permits required: No sign may be erected/altered/maintained until a sign permit is issued by the building official; electrical permits separately required for electric signs. § 17.50.040.
Design & construction: Signs must meet recognized engineering principles and the California Building Standards Code (Title 24) for structural and material standards; plastics, glass, and limits on combustible materials are spelled out. § 17.50.070.
Maintenance and inspections: Owners must keep signs and supports in good repair; the building official may inspect and order removal/repair. § 17.50.050 and § 17.50.060.
Temporary signs: Allowed in addition to permanent signs but limited in area and duration (total temporary signage cannot exceed 40% of permanent sign area allocation; individual limits and maximum duration exist). Grand‑opening exceptions apply. § 17.50.210.
Portable A‑frame signs: A distinct temporary sign permit is required, encroachment permit required if in the public right‑of‑way, strict size, material, sidewalk clearance and insurance requirements (minimum 5 ft pedestrian clear zone; tagging by community development). § 17.50.220.
Nonconforming signs: Signs legal when installed but conflicting with the current code are nonconforming and must be removed or brought into compliance under triggers (damage >50% of replacement cost, relocation, abandonment, etc.). Planning Commission may waive for historic signs under criteria. § 17.50.170.
Conditional / discretionary approvals: The Planning Commission (or City Council on appeal) may approve sign modifications with conditions (including projection, height, area) as part of a precise development plan; findings are required to show compatibility and no material harm to existing signs. § 17.50.180.

Key numeric rules — quick reference table

Topic	Numeric / qualitative standard	Code Reference
Permanent sign area (general allocation)	2 sq ft per lineal foot of building frontage; minimum 20 sq ft; double‑faced: count one side + 1/2 of the other	§ 17.50.120(D)(1)
Window sign coverage	Window signs counted toward total; cannot obscure more than 20% of glass area	§ 17.50.120(D)(5)
Signs above first story	Max height 28 ft above adjacent street grade or top of second story, whichever higher	§ 17.50.120(D)(6)
Ground sign height (general)	Ground signs not to exceed 10 ft from grade to top of sign body (exceptions apply); in C‑2 max 8 ft	§ 17.50.120(C)(3)
Temporary signs (total duration)	Temporary display limited to 90 days per calendar year for any business (with some exemptions)	§ 17.50.210(B)
Portable A‑frame size	Min 28" tall × 18" wide; Max 42" tall × 24" wide; base spread 24–30"; minimum 5 ft sidewalk clearance; insurance & tag required if on ROW	§ 17.50.220(B–C)
Nonconforming sign removal triggers	Destroyed/damaged > 50% replacement cost; altered/enlarged; abandoned > 90 days; dangerous or traffic hazard	§ 17.50.170(A)
Permit requirement	Sign permit required before erection/alteration; separate permit per business or sign group	§ 17.50.040(A–B)

Practical guidance & interactions with related requirements

Prepare a comprehensive site sign plan for multi‑tenant or new commercial developments: the code requires a comprehensive sign plan showing location, size, color and elevations as part of plan submittals (§ 17.50.040(C)). This is essential for projects subject to Hermosa Beach Design Review or precise development plan review.
Design and materials must comply with the California Building Standards Code (structural, materials and electrical), per § 17.50.070 (design and construction). For electrical signage you will need the electrical permits called out in § 17.50.040.
Sign area calculations rely on building frontage definitions in Title 17; changes in building frontage (secondary frontage, multiple street frontages) change sign entitlement — consult the building‑frontage rules in Title 17.
If your property sits in an overlay or historic district, the Hermosa Beach Overlay Districts and Hermosa Beach Historic Preservation rules can add restrictions or design requirements beyond Chapter 17.50; murals or historic signs may require the Planning Commission’s discretionary approval. Verify with the planner.

Checklist (what an applicant must satisfy)

Determine zone and whether use is residential, mixed, or commercial (verify district: C‑1, C‑2, C‑3, R‑P, etc.). Verify with the planner.
Confirm allowed sign types & counts for that district (see the district subsections in § 17.50.120, § 17.50.130, § 17.50.140).
Calculate allowable permanent sign area: 2 sq ft/ft of frontage, min 20 sq ft, and check wall‑coverage caps (≤ 25% of façade). § 17.50.120(D).
Prepare required drawings for sign permit (elevations, location on building/parcel, electrical details if applicable) per § 17.50.040(B–C).
If temporary/portable A‑frame sign: apply for temporary sign permit and encroachment permit if on ROW; provide insurance if placing on public sidewalk. § 17.50.220(A).
Confirm compliance with structural/material rules and obtain electrical permits where needed (see § 17.50.070 and § 17.50.040).
If project is new multi‑tenant development or otherwise discretionary, include sign theme/plan in the development submittal and expect design review. § 17.50.040(C) and see Hermosa Beach Design Review.

Risks & Ambiguities

Issue	Why it matters	What to verify
Nonconforming sign triggers	Repairing/altering a nonconforming sign can force removal if change exceeds 50% of replacement cost (trigger for compliance). § 17.50.170	Verify existing sign’s legal status and damage/alteration thresholds before budgeting repairs.
Frontage calculation ambiguity	Building frontage definition affects sign area entitlement (primary vs. secondary street). Title 17 definitions determine calculation.	Confirm exactly which lot face counts as primary frontage for your tenant; get planner confirmation.
A‑frame on sidewalk (ROW)	A‑frames in ROW need encroachment permit, insurance, and minimum clearance; enforcement is strict. § 17.50.220	If you plan sidewalk placement, get encroachment permit and proof of insurance before placement.
Historic or mural exceptions	Murals and historic signs may be treated differently, but require Planning Commission action and findings. § 17.50.130(B) and § 17.50.170(B)	If sign is old or artistic, request pre‑application review with Historic Preservation staff/Planner.
Overlap with Building Code	Structural, fire, and electrical code compliance is required; building permits and code compliance are separate from sign zoning allowances. § 17.50.070 and § 17.50.040	Confirm which Building Division permits are required and plan coordinated submittal (structural calculations, electrical).

Plain-English Summary

Hermosa Beach’s sign rules (Title 17, Chapter 17.50) set how big, how many, where and what kinds of signs you can have depending on your zone (residential, C‑1, C‑2, C‑3, OS, etc.). Most signs need a sign permit, must meet the design/construction rules tied to the California Building Code, follow area/height limits (2 sq ft per foot of frontage, minimum 20 sq ft, various height caps), and temporary or sidewalk A‑frame signs have special permit and insurance requirements. Always check whether your property is in a special overlay or historic area because the Planning Commission may impose stricter or discretionary controls.

Frequently asked questions

What signs are allowed on a single‑family R‑1 lot in Hermosa Beach?

Hermosa treats single‑family residential signage conservatively: small building identification and one real‑estate sign per frontage are allowed under the residential sign rules referenced in § 17.50.090; temporary signs follow the limits in § 17.50.210. Verify the precise allowances for your property with the planner because multi‑family or accessory commercial uses change the rules.

How do I calculate allowable sign area for a storefront in Hermosa Beach?

Permanent sign area is generally computed as 2 sq ft per foot of lineal building frontage, with a minimum of 20 sq ft; double‑faced signs count as one side plus half the other. See § 17.50.120(D) for the formula and applying secondary frontages.

Can I put an A‑frame sign on the sidewalk in downtown Hermosa (C‑2)?

You can place an authorized portable A‑frame in commercial frontages including sidewalks, but it requires a temporary sign permit (and an encroachment permit if on City right‑of‑way), a liability insurance rider, a city tag on the sign, and a minimum 5 ft clear pedestrian path. See § 17.50.220 for size, design and permit requirements.

Do I need a sign permit if I repaint an existing sign or change copy?

Repainting or cleaning is not an alteration that requires a sign permit unless you change structure, copy type, or color (structural/copy changes do require a permit). The general permit requirement is in § 17.50.040 and repainting is explicitly exempt unless it involves structural or copy changes.

What happens to a sign that was legal under an older code but no longer complies?

Such a sign is a nonconforming sign. Nonconforming signs must be removed or brought into compliance if certain events occur, such as damage exceeding 50% of replacement cost, relocation, abandonment >90 days, or alterations (other than routine copy replacement). The triggers and possible Planning Commission exceptions are in § 17.50.170.

Are illuminated signs allowed along the open‑space edge or in parks?

In OS/OS‑1 zones, signs should be constructed of natural‑appearing materials and shall not be illuminated except where necessary for safety; importantly, all new signs in OS zones require Planning Commission approval under § 17.50.110.

Can a multi‑tenant commercial project use a different sign area allocation per tenant?

Yes — the code requires a comprehensive sign plan on proposed multi‑tenant commercial developments and calculates allowable area per entity based on each tenant’s building frontage (and secondary frontage rules). Prepare a consolidated sign plan to show allocation and theme per § 17.50.040(C) and § 17.50.120(D).

If my parcel sits in an overlay or historic area, can I get an exception for a mural or old sign?

Possibly. Murals may be permitted by the Commission and the Planning Commission can waive certain provisions for signs of historic value under the exceptions in § 17.50.170(B) and the mural allowance language in the C‑zone sections. Always verify with the Hermosa Beach Historic Preservation staff and plan for discretionary review.

Where do I find the structural/material rules that signs must meet?

Sign design and construction must conform to recognized engineering principles and the California Building Standards Code; the code’s design and material requirements are in § 17.50.070 and electrical sign rules are tied to the electrical code.
