Los Gatos — Signage

Signage under the Los Gatos local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

This page summarizes what the Town of Los Gatos zoning ordinance (Chapter 29) actually requires for signs: who decides, numeric limits, temporary‑sign rules, prohibited signs, nonconforming sign handling, and how overlays or the downtown (C‑2) area change the rules. For general orientation to related local pages see the Los Gatos zoning & planning overview. Key controlling text appears in Divisions 2–3 of Article I (sign rules) and in zone-specific chapters; citations to the ordinance sections are provided next to each rule so you can check the source language.

Notes on reading: the code treats signs as a Town‑wide system (applies in all zones) but then gives separate numeric allowances for residential vs nonresidential zones, plus special rules for events, subdivisions, PD overlays and downtown (the C‑2 zone). See § 29.10.105, § 29.10.110, § 29.10.120, § 29.10.125 and § 29.10.135 for the core rules.

How the code is organized (quick orientation)

The Town treats sign regulation as a single "Signs" division in Chapter 29 with general standards and then zone‑by‑zone allowances. See § 29.10.100—29.10.140 (definitions, permits, exceptions, temporary signs, standards, zone tables).
For zone names and zone‑specific development rules you should consult the applicable zone chapter (e.g., residential article, commercial article) and the Town zoning map — e.g., residential zones are established at § 29.40.010 and commercial/downtown rules appear in the C‑2 chapter.

District‑by‑district signage guidance (Los Gatos‑specific)

Note: the sign chapter is written to apply across all zones; the zone subsections below summarize how the sign chapter (§ 29.10.100 et seq.) allocates area/number/height by zone and then point to the underlying zone purposes or special procedures when relevant. Always verify with the Planning Director for parcel‑specific decisions.

R‑1 (Single‑Family Residential) — purpose & where it applies

Purpose / typical uses: single‑family homes and accessory uses in areas designated under the residential article; see § 29.40.010 for the residential zone establishment.
Sign rules that apply: the sign division applies Town‑wide; in residential zones the ordinance sets small allowances for sale/identification signs and neighborhood identification signs in § 29.10.135(b).
Key numeric standards for signs on residential parcels:
- Nameplates up to 1.5 sq ft, up to 6 plates per building (exceptions/no permit) — § 29.10.110(2).
- Temporary fence/building sign for property for sale/lease: 6 sq ft in residential zones (no sign permit required under the exceptions rules) — § 29.10.110(5)(a).
- Neighborhood identification ground signs generally limited to 24 sq ft (see § 29.10.135(b) and deciding‑body location controls).
Practical: most homeowners will rely on the § 29.10.110 exceptions (small nameplates, window signs up to 25% of pane, convenience signs, etc.); larger freestanding or illuminated signs in residential zones require a permit and must meet the limits in § 29.10.135(b).

R‑M (Multiple‑Family Residential) — purpose & where it applies

Purpose / typical uses: multi‑family dwelling regulations appear in the residential article; R‑M is treated as a residential zone for signs.
Sign allowances: § 29.10.135(b) gives specific totals by size of development:
- For multiple‑family developments < 10 units — one wall sign per lot frontage, 18 sq ft allowed.
- For multiple‑family developments ≥ 10 units — one wall sign per lot frontage, 24 sq ft allowed.
Practical: signs that identify a multifamily property are modest by design; anything illuminated or freestanding beyond these limits requires review under the general standards (§ 29.10.125) and a sign permit.

C‑2 (Central Business / Downtown) — purpose & where it applies

Purpose / typical uses: the C‑2 zone is the downtown / central business district; the code explicitly defines “Downtown Area” as the C‑2 zone for sign/event rules.
Sign rules that apply: nonresidential calculations in § 29.10.135(c) and the event sign limits use C‑2 as the downtown reference.
Key dimensions & special allowances:
- Downtown frequently gets special treatment for streetscape improvements and restrictions on yard rules (§ 29.60.337) which affects where signs or improvements can go (e.g., allowed improvements in front yards if findings are met).
- Event signs in town are limited so that, except as noted, no more than one (1) event sign per event in the downtown area and event sign area cannot exceed the total sign area calculation under § 29.10.135.
Practical: downtown businesses should compute allowable sign area using the business‑frontage rules in § 29.10.135(c) (one sq ft per lineal foot primary frontage or the alternative formula) and expect design review; see Los Gatos Design Review.

CH (Restricted Highway Commercial), O (Office), CM (Controlled Manufacturing) — nonresidential zones

Purpose / typical uses: each nonresidential zone lists permitted uses in its chapter (for example CH permitted retail, services, limited manufacturing; O has office standards; CM has controlled manufacturing uses). See § 29.60.415–420 (CH), § 29.60.100–115 (O), § 29.70.235–245 (CM).
Sign allowances: nonresidential sign area and allocation follow § 29.10.135(c) and the numbered rules that follow (business‑frontage calculation, total parcel cap, special rules for shopping centers and vehicle sales).
Typical dimensional examples you will use:
- Default attached sign area: 1 sq ft per lineal foot of primary business frontage (some frontages use a 1:0.5 ratio for secondary frontage; see rules (1) and (2)).
- Total area cap: the total of all signs on a parcel shall not exceed 1 sq ft of sign area per lineal foot of lot frontage unless limited by the business‑frontage calculation (rule (4)).
- Construction or subdivision development signs have fixed numeric caps (e.g., 25–64 sq ft depending on lot size, and 15 ft max height for many freestanding or subdivision signs) — see § 29.10.120 and § 29.10.135.
Practical: compute allowed area by frontage; verify whether your use is a “shopping center” (special exceptions) and whether a freestanding ground sign is exempt from total area limits for shopping centers or vehicle sales per § 29.10.135.

Planned Development overlay (PD)

Purpose: the PD overlay authorizes a site‑specific development plan; signs shown on the official PD development plan may be erected per that plan. See § 29.80.075 et seq. and § 29.10.135(d).
Practical: if your parcel has a PD overlay the approved PD plan controls signage allowances (the PD plan may deviate from the zone defaults). Check the PD plan and the Overlay Districts page.

Landmark / Historic Preservation overlay (LHP)

Purpose & effect: work on signage that affects designated landmarks, historic districts, or pre‑1941 structures may need review under the historic preservation rules; design findings are required. See § 29.80.230—29.80.290.
Practical: signs on landmark properties may require Historic Preservation Committee or Planning Commission review in addition to the regular sign permit; always check Los Gatos Historic Preservation rules.

Public School overlay (PS)

Purpose: the PS overlay adopts school‑related standards; the code says overlay zones do not remove other applicable Town requirements. Signs for schools remain limited by the sign division but certain bulletin boards and community signage on school property are recognized; see § 29.80.430 and § 29.10.135(b) for bulletin board allowances.

Practical checklist (what an applicant must satisfy)

Confirm whether the proposed sign is covered by an exception (nameplate, window sign, convenience sign) — review § 29.10.110.
Calculate allowable sign area using § 29.10.135 (residential table or nonresidential frontage formulas) and include the calculation in the application.
Meet the design/compatibility standards in § 29.10.125 (materials, illumination limits, projecting sign clearances). See Los Gatos Development Standards and Los Gatos Design Review for complementary street‑level design rules.
If in a historic district or on a designated landmark property, obtain design review approvals required under § 29.80.260—290 before a sign permit is finalized. See Los Gatos Historic Preservation.
For temporary or event signs, ensure removal dates and number/area limits per § 29.10.120 and include securing/removal plan in the application.
Verify any public right‑of‑way placements (special permission required; many temporary signs are prohibited on public property) — § 29.10.120 and § 29.10.110 list limited on‑public‑property allowances.
If the sign involves illuminated electrical work or structural support, coordinate with the Building Official and check Title 24 requirements (California Building Standards Code) for building permits and structural/safety compliance.

Risks & Ambiguities

Issue	Why it matters	What to verify
Sign area calculation across multiple frontages	The ordinance offers two different business‑frontage formulas and caps; using the wrong one can lead to an over‑sized sign that will be denied.	Verify which frontage is "primary" and which formula applies for your parcel per § 29.10.135(c)(1)–(2).
Whether a sign is “attached” vs “freestanding” (affects area and amortization)	Classification changes the measurement method, allowed area, and the amortization schedule for nonconforming signs.	Confirm classification and measurement method with the Planning Director; see definitions at § 29.10.100 and measurement rules in § 29.10.135.
Historic overlay requirements	Landmark/historic sites may require additional committee review that can change allowable design/dimensions.	Verify whether the property is in a LHP overlay and whether Historic Preservation Committee or architecture and site approval is required (§ 29.80.260—290).
Downtown (C‑2) exceptions and event sign limits	The downtown area has stricter event sign limits (e.g., one per event in downtown). Misreading this can cause code violation during civic events.	Confirm "Downtown Area = C‑2" and event limits in § 29.10.120 and related subsections.
Nonconforming sign amortization schedule	Different sign characteristics have different amortization periods; removal deadlines can be enforced.	Check amortization timelines and the Planning Director’s nonconforming list — § 29.10.140(f) and related notice procedures.
ADU signage specifics	The code does not provide ADU‑specific sign rules in the retrieved materials.	Not found in retrieved materials — verify with the Planning Director or Los Gatos ADUs page for any local practice.

Plain‑English summary

Los Gatos regulates signs in one place (Chapter 29) and then tells you how many square feet and what kinds of signs are allowed depending on whether your property is in a residential zone (modest wall and ground signs) or a nonresidential zone (area calculated from your business frontage), with special rules for downtown, planned developments, and historic districts; read § 29.10.110, § 29.10.120, § 29.10.125 and § 29.10.135 and get a Planning Director pre‑application if your sign is near any boundary or is illuminated.

Frequently asked questions

What signs can I erect on a single‑family (R‑1) lot in Los Gatos without a permit?

Small exceptions are allowed without a sign permit: nameplates up to 1.5 sq ft (up to six per building), window signs up to 25% of the window area, convenience signs up to 2 sq ft, and certain for‑sale or for‑lease temporary signs (residential frontages 6 sq ft for sale/lease under § 29.10.110). For anything larger or illuminated you must apply for a sign permit. § 29.10.110

How do I calculate allowable sign area for a downtown business on a C‑2 frontage?

For nonresidential frontages the ordinance uses business‑frontage formulas: generally 1 sq ft of sign area per lineal foot of primary business frontage (alternatives/limits apply for secondary frontages); the total on a parcel is limited by the frontage calculation or 1 sq ft per lineal foot of lot frontage depending on the rule that applies — see § 29.10.135(c) and the numbered rules that follow. § 29.10.135(c)

Can I put up an illuminated billboard or projected light sign in Los Gatos?

No — off‑premises signs and billboards are generally prohibited except for narrow exceptions (subdivider off‑premises signs, certain directional signs). Projected‑light signs and billboards are specifically listed as prohibited in § 29.10.130. Illumination of allowed signs must meet brightness caps (max 150 foot‑lamberts, and signs > 30 foot‑lamberts must be set back 50 ft from residential zones unless not visible). § 29.10.130; § 29.10.125(6)–(7)

If my sign is nonconforming, how long do I have to bring it into compliance or remove it?

The code sets amortization periods: painted‑on wall signs and certain roof/suspended marquee signs have 2 years; freestanding, wall, projecting signs and others generally have 5 years — see the nonconforming sign schedule in § 29.10.140(f). The Planning Director must list and notify owners of nonconforming signs. § 29.10.140(f)

Are temporary event signs allowed in the downtown area, and are there limits?

Yes, but with limits: event signs require a permit under § 29.10.120; except as provided, no more than one (1) event sign per event is permitted in the downtown (C‑2) area, and the sign area cannot exceed the total area permitted under § 29.10.135. Also event signs can generally be posted up to 14 days before and must be removed within 24 hours after the event (there are additional numeric and location limits). § 29.10.120

Who issues sign permits, and can I appeal a refusal?

The Planning Director issues sign permits where action is not required of the Council or Planning Commission; the director also hears many sign applications and maintains the nonconforming sign list. Any interested person may appeal a Planning Director decision to the Planning Commission within the appeal timelines in the code. See § 29.20.255 and related appeal provisions. § 29.20.255

Do historic‑district signs need special approval beyond a sign permit?

Yes — signs on designated landmarks or in historic districts may require architecture/site approval and review by the Historic Preservation Committee or Planning Commission; the historic preservation divisions set the permit and design rules for designated properties. See § 29.80.260—290. § 29.80.260—290

Can I place directional or pedestrian wayfinding signs on public property?

Generally temporary signs on public property and in the public right‑of‑way are prohibited except for limited exceptions listed in § 29.10.110 and § 29.10.120; pedestrian directional signs for entrances can be allowed as small on‑premises signs (e.g., 1 sq ft pedestrian directionals). Always obtain express Town permission if any sign is proposed on public property. § 29.10.110; § 29.10.120

Are there exceptions for signs in a Planned Development (PD)?

Yes. A PD’s official development plan can specify the signs that may be erected within that PD; where a PD plan exists, signs shown on that plan may be erected per the PD rather than the standard zone table. See § 29.10.135(d) and the PD division. § 29.10.135(d); § 29.80.075

If I need structural connections or electrical for an illuminated sign, what else do I check?

Sign structural supports and electrical work can trigger Building Official or Title 24 (California Building Standards Code) permits; the sign division notes that building permits may still be required and that building‑code standards govern structural/safety aspects. Coordinate with the Building Official and consult the California Building Standards Code. § 29.10.105; California Building Standards Code ---
