Hidden Hills — Signage

Last reviewed: July 2, 2026

Overview

This page explains what the Hidden Hills Land Use and Zoning regulations allow and require for signs (on‑site identification, building‑mounted, portable sandwich signs, and small residential signs). It is grounded in the City’s Land Use and Development Ordinance (Title 5) and points to the Architectural/Site Plan review and Building Code adoption that affect sign design and approvals. Always verify parcel‑specific treatment with the Planning Director because discretionary review and the Community Association process can change outcomes. Key controlling citations are collected below.

• If your sign relates to vehicle areas see parking.
• If your sign location might affect yards or massing, check Hidden Hills Development Standards.
• Signs frequently need design review or architectural/site plan review.
• If an overlay could apply, see Hidden Hills Overlay Districts.

District-by-district rules (what the ordinance actually says)

R-1 (Single‑family residential)

Purpose & where it applies

• The R-1 district is Hidden Hills’ single‑family residential zone (Article E). Permitted uses and accessory rules are in § 5-2E-1.

Sign rules (practical summary)

• Residential lots: generally no signs are permitted, with two narrow exceptions: one unlighted name/address sign for the household or the property name, up to 6 square feet; and normal "For Sale"/"For Lease" real estate signs are allowed. See § 5-2E-1.D.

Typical permitted uses/context

• Signs that identify the resident or property ONLY (no commercial advertising) and small real estate signs during sales. See § 5-2E-1.D.

Practical notes

• If you live in Hidden Hills and want anything beyond a nameplate or a sale sign (e.g., a larger illuminated address sign or private directional signs), expect to need confirmation from Planning and potentially a variance. See the enforcement provisions § 5-2J-1 (violations/penalties) for consequences if you exceed the allowance.

RA‑S and RA‑S‑2 (Estate / larger residential lots)

Purpose & where it applies

• RA‑S and RA‑S‑2 are larger‑lot residential districts; permitted uses and sign allowances are in the RA articles (Article C and Article D). See § 5-2C-1 and § 5-2D-1.

Sign rules (practical summary)

• RA‑S: “No signs shall be permitted or maintained on any lot or parcel, except…” with a narrow exception of one unlighted or low‑voltage (≤15 W) sign up to 6 square feet for name/address, plus standard "For Sale"/"For Lease" allowances. See § 5-2C-1.E.

Practical notes

• Demonstration estates and certain subdivision sales promotions may have special, limited sign permissions (see RA‑S‑2 allowances). For any nonstandard sign in these zones, expect discretionary treatment.

Commercial (Commercial / Commercial‑Restricted)

Purpose & where it applies

• The City’s Commercial (Commercial‑Restricted) zone rules are in Article F (5‑2F). Commercial properties and offices located in the City are subject to both the zone rules and mandatory Architectural & Site Plan Review. See § 5-2F and especially the site plan review requirement § 5-2F-6.

Sign rules (decision‑relevant standards)

• Freestanding (monument) signs: One monument‑style building identification sign is allowed per primary building; may be within required front yard (but not side/rear unless adjacent to a public street); maximum 6 feet in height and 20 square feet in area. These must be complementary in material/style to the building and are subject to approval. See the Commercial article (Signs) under § 5-2F.
• Building‑mounted (wall) signs: An occupant is permitted up to 2 sq ft of sign area per lineal foot of building or suite frontage; area calculation is the rectangular bounding box of the sign; sign materials and color/frames must be wood and complementary; multiple signs on the same site must match in style. See the Commercial article (Signs) under § 5-2F.
• Real‑estate sandwich / A‑frame signs (for real estate offices): One unlighted sandwich board per primary real estate office, max 4 ft tall by 2 ft wide; allowed in required front yard outside the street right‑of‑way but not in side/rear yards unless adjacent to a street; no lighting or decorations; allowed hours 9:00 a.m.–6:00 p.m. daily. See the Commercial article (Signs) under § 5-2F.
• Design and illumination: Specific location, height, size, material and illumination of freestanding signs and any departures from the standard must be reviewed and approved with the Architectural and Site Plan Review. See § 5-2F-6.

Practical notes

• The Planning Agency (or Director on appeal) must approve sign materials, color, and style; wood frames and non‑reflective finishes are heavily favored. Expect the Planning Agency to require signs that “contribute to the image of Hidden Hills” (design standard in § 5-2F-6.B.5).

Quick reference table — Decision‑relevant items

Checklist (what an applicant must satisfy)

• Confirm your property zoning (R-1, RA‑S, Commercial) via the City zoning map. See Hidden Hills Zoning.
• Verify the sign type and that it fits the numeric limits (6 sq ft for residential nameplate; 6 ft / 20 sq ft for commercial monument; 2 sq ft per lineal ft for building signs). Cite the relevant § when preparing materials (§ 5-2E-1.D, § 5-2F).
• For commercial or any non‑standard sign, prepare architectural/site plans showing size, materials, lighting, mounting details and context views for § 5-2F-6 review.
• If sign is illuminated, check allowable lighting levels and confirm compliance with City lighting rules and Building Code lighting/energy rules (see California Building Standards Code link).
• Confirm setbacks and placement relative to rights‑of‑way and public streets (if in front yard, sign may not be in street ROW). Use development standards to check yards.
• If within an Overlay (ridgeline, historic, etc.), check overlay limitations via Overlay Districts.
• If you are in a Community Association jurisdiction within the City, get the Association sign approval (the City references Community Association design standards in site review). Verify with the Planning Director. Verify with the jurisdiction.

Risks & Ambiguities

Plain-English Summary

Hidden Hills keeps signs minimal and design‑oriented: residential lots get a single small name/address sign (up to 6 sq ft); commercial sites can have one monument (up to 6 ft tall / 20 sq ft) plus building signs sized at 2 sq ft per linear foot, but most commercial signs must pass Architectural & Site Plan Review and match the city’s wood/nonreflective material preferences. Always check with Planning because design review, overlays, Community Association rules, and the Building Official can change what’s permitted. See § 5-2E-1, § 5-2F, and § 5-2F-6 for the controlling ordinance text.
