Cupertino — Signage

Q: What sign permit do I need for a new blade sign in Cupertino?

Blade (pedestrian) signs are regulated in the Permanent Signs table; they are allowed in all except residential districts , limited to 6.5 s.f. and mounted 8–12 ft above pedestrian walkways; if not exempt you must apply for a sign permit to the Director and meet design criteria ( § 19.104.150 , § 19.104.030 , § 19.104.220 )

Q: How much of my storefront window can be used for permanent signage?

Permanent window signs are counted as part of your wall sign area and may cover up to 25% of each storefront bay; neon window signs are counted as 4 s.f. ; one “OPEN” sign under 2 s.f. is exempt — see § 19.104.150 .

Q: Are illuminated signs allowed and how bright can they be?

Yes, but illuminated signage must meet intensity guidance: approximately 250 foot‑lamberts in commercial/office/industrial districts and 100 foot‑lamberts in other districts. The Building Inspector/Planner can require reduction if the sign is found to exceed standards or create a traffic/residential nuisance (see § 19.104.230 and § 19.104.060 ).

Q: Do I need a Sign Program for my shopping center?

If the development contains four or more tenant spaces (commercial, office, industrial or mixed projects), the owner must submit a Sign Program meeting the content and finding requirements of § 19.104.130 ; the Director reviews and approves subject to those findings.

Q: Are electronic readerboard or animated signs allowed?

Animated signs are generally prohibited; limited temporary animated devices (banners, flags) or electronic readerboard signs may be permitted only where expressly authorized by the code and subject to the restrictions in § 19.104.110 and related tables. Verify the specific allowance and standards for electronic readerboards in the applicable table.

Q: What happens if the City finds my sign is unsafe or illegal?

The Director may summarily remove any sign deemed an immediate peril to public safety ( § 19.104.350 ). Costs are charged to the responsible party, unclaimed signs may be disposed of, and illegal signs are subject to nuisance abatement and infractions( § 19.104.360–.380 ).

Q: Does a specific plan (Monta Vista, Heart of the City) change the sign rules?

Yes — businesses inside areas regulated by a specific plan must follow the sign regulations in that plan first; where the specific plan is silent Chapter 19.104 applies ( § 19.104.120 ). Confirm plan text for the parcel and reconcile with the sign chapter.

Q: Are roof signs or billboards allowed in Cupertino?

Permanent roof signs are expressly prohibited, and off‑site billboards are generally prohibited except in narrowly defined exceptions; consult § 19.104.110 for the list of prohibited sign types.

Q: If I change only the face of an existing multi‑tenant sign, do I need a permit?

“Change of face” (replacement of copy/letters) is regulated; if a property is subject to a Sign Program or if the change would exceed current allowed area, a permit or compliance with the existing Sign Program is required. Where a change of face triggers a required review the Director’s sign permit application rules in § 19.104.040 and review criteria in § 19.104.050 apply.

Q: How are ground sign heights measured?

Ground sign height is measured from the grade of the adjoining closest sidewalk to the top of the sign, including trim; see the ground sign rules and Appendix examples in § 19.104.160 and Appendix A. ---

Overview

This page summarizes Cupertino’s local sign rules as adopted in Title 19 (CHAPTER 19.104: SIGNS) of the Municipal Code. It explains the permit framework, the common numeric limits (window, blade, wall, ground, temporary), design and illumination controls, prohibited signs, and special‑district rules you must check before making or changing signage. Key administrative rules (permit, appeals, inspections, removal, penalties) are controlled by § 19.104.030 through § 19.104.380.

Note: when this page refers to dimensional or setback context you should also check the city’s development standards. When a design judgment or consistency with building/façade elements is required, expect design review under Cupertino’s rules. Linkages with vehicle parking and circulation are relevant; consult the City’s parking rules where vehicle signs or directional signs interact with lot layout.

Regulatory framework — headline rules (what matters first)

Permit required for all non‑exempt signs: § 19.104.030 (Director reviews in 30 days)
Signs exempt from permit are listed in § 19.104.100 (small ID signs, political signs within limits, informational signs under 4 s.f., etc.)
Prohibited signs include roof signs, most portable/vehicle signs as advertising, animated signs (with narrow temporary exceptions), and off‑site billboards except where limited exceptions apply: § 19.104.110
Design criteria that guide approval (compatibility, landscaping around ground signs, internal illumination control, motorist safety) are in § 19.104.220 and must be met for permit approvals.
Illumination intensity ceilings: approx. 250 foot‑lamberts in commercial/office/industrial districts and 100 foot‑lamberts in all other districts: § 19.104.230.

Where physical safety, construction, or electrical compliance is required the sign must meet applicable building and electrical code requirements referenced in § 19.104.090; verify structural/installation compliance with the California Building Standards Code.

District-by-district breakdown

Below are the Cupertino districts most relevant for signage. Each subsection lists purpose/typical sign uses, key numeric limits or prohibitions from the sign chapter, and where those rules apply. Always confirm a parcel’s exact zoning designation and any special plan/overlay that may override these rules.

R-1 (Single‑family residential)

Purpose / typical permitted signage: residential identification (address numbers), political signs, temporary garage sale signs, real‑estate for‑sale signs, and limited flags for model homes. See sign exemptions and temporary signs rules in § 19.104.100 and § 19.104.260.
Key limits: most identification/informational signs under small size thresholds are exempt; blade signs and commercial multi‑tenant signage are explicitly excluded from residential coverage (blade signs allowed “all except residential districts”) (see § 19.104.150).
Where it applies: residential lots throughout the city subject to standard residential development rules; design guidance/notice rules for public noticing can apply under Chapter 19.12 (review procedures).

(Also applies to A, A‑1, and RHS zones for single‑family patterns — verify parcel zoning.) Verify with the jurisdiction for ADU or other special residential situations; see the City’s ADU page for policy context. ADUs

R-2 / R-3 / R-4 / R1C / TH (Duplex, small multi‑family, townhomes)

Purpose / typical permitted signage: building identification, unit address signage, temporary real‑estate and directional signage, and limited identification signage for multi‑family developments. Temporary and real‑estate signs are regulated in § 19.104.260; directory and project signs follow similar temporary/permit rules.
Key limits: multi‑unit developments (and any project with four or more tenant spaces) will generally be required to adopt a Sign Program (see § 19.104.130) if the property is commercial or mixed‑use in nature; for strictly residential complexes, development entry “development identification signs” are defined and restricted (see the definitions and § 19.104.150 / § 19.104.160 for ground/development entry signage).

Commercial (all commercial zones), Office, Industrial, Planned Zoning Districts

Purpose / typical permitted signage: business identification (wall, ground, window, blade), tenant directories, and directional signage for customers. Commercial/office/industrial districts have the broadest area allowances and higher illumination caps (§ 19.104.230).
Key numeric standards (decision‑relevant):
- Wall signs: typically computed as 1 s.f. of sign area per linear foot of business frontage with a 70% frontage cap (see the wall sign table references in the sign tables and § 19.104.140).
- Permanent window signs: up to 25% of a storefront bay’s window surface (neon window sign counted as 4 s.f.) and an “OPEN” sign under 2 s.f. is exempt — see § 19.104.150.
- Blade (pedestrian) signs: 6.5 s.f. maximum, installed 8–12 ft above pedestrian walkways, allowed in “all except residential districts” (inspection/approval depending on illumination) — § 19.104.150.
- Logos / insignia: 9 s.f. maximum where allowed and subject to secondary restrictions in § 19.104.190 and design criteria § 19.104.220.
- Ground signs: see § 19.104.160 for ground‑sign rules (height measured from adjoining sidewalk grade to top of sign; landscaping required around ground signs per design criteria § 19.104.220).
Sign programs: any commercial, office, industrial or residential development with four or more tenant spaces must adopt a Sign Program; applications require site plans, computations of total allowed sign area, and sign specifications; the Director may approve upon findings in § 19.104.130.

Special Planning Districts / Specific Plans (Monta‑Vista, Heart of the City, etc.)

Purpose / typical permitted signage: areas governed by a specific plan apply the specific plan’s sign rules first; where the specific plan is silent the City sign chapter applies. See § 19.104.120 (special planning districts).
Where to check: consult the applicable specific plan and the City’s overlay districts material; for historic landmark signs see the City’s historic preservation program which preserves designated landmark ground signs (Appendix B) and exempts them from some nonconforming rules (§ 19.104.210).

Checklist (what an applicant must satisfy)

Confirm zoning of parcel and any applicable specific plan/overlay; check special district rules (§ 19.104.120) and the City’s overlay resources.
Confirm sign type is not exempt or prohibited (compare to § 19.104.100 and § 19.104.110).
Prepare a sign permit application with drawings, materials, colors, dimensions, illumination type and intensity, mounting details, and site plan per § 19.104.040.
Confirm numeric limits relevant to your sign type (window %; blade 6.5 s.f.; logo 9 s.f.; wall area computation) and reconcile with any required Sign Program if 4+ tenants (§ 19.104.130).
Demonstrate compliance with Design Criteria (§ 19.104.220): materials, compatibility, landscaping around ground signs, and non‑distracting illumination.
Provide illumination calculations and be prepared for post‑installation light measurement/adjustment per § 19.104.060 and § 19.104.230.
Ensure construction details meet structural/electrical requirements in § 19.104.090 and obtain building/electrical permits as required (coordinate with Building division and verify with the California Building Standards Code).
Pay fees and be prepared for review times and appeal/reset procedures per § 19.104.030, § 19.104.070, and Chapter 19.12.

Risks & Ambiguities

Issue	Why it matters	What to verify
Off‑site vs on‑site determination	Off‑site signs (billboards) are generally prohibited; mislabeling a sign can trigger removal and nuisance actions (§ 19.104.110, § 19.104.370)	Confirm sign message targets the occupant of the parcel and check off‑site definition in the sign chapter.
Landmark / nonconforming signs	Landmark signs have special exemptions but modifications are restricted (§ 19.104.210)	Check Appendix B (Landmark Signs) and verify allowed minor modifications with Director.
Illumination measurement & complaints	Foot‑lambert caps are advisory thresholds but staff can require dimming per § 19.104.060/230; neighbors or traffic safety can trigger reductions	Provide photometric data and be prepared for on‑site measurement and required reduction.
Special plans override	Monta Vista, Heart of the City, and other specific plans may contain their own sign standards (§ 19.104.120)	Pull the specific plan language and reconcile it with Chapter 19.104; when in conflict, the specific plan controls.
Sign program scope	Sign Programs are required for multi‑tenant projects and can change allowed totals; failing to submit a program can block permits (§ 19.104.130)	If 4+ tenants, prepare a Sign Program submittal with the computations required by the Director.
Intersection sight triangles & pedestrian clearances	Signs that block sight lines or obstruct access are flatly prohibited (§ 19.104.080)	Check Standard Detail 7‑6 (Sidewalk Sight Triangle) in Appendix C and coordinate with Engineering.

Plain‑English Summary

Cupertino’s sign ordinance (CHAPTER 19.104) requires a permit for most signs, limits sign sizes by type (for example, blade signs 6.5 s.f., window signs 25% of window area, logos 9 s.f.), controls illumination (≈250 ft‑L in commercial vs 100 ft‑L elsewhere), and preserves special rules in specific plans and for landmark signs. Follow the design criteria and submit a complete sign permit package to the Director; illegal or unsafe signs can be removed and penalties imposed.
