Monte Sereno — Signage

Last reviewed: July 2, 2026

Overview

This page summarizes what the Monte Sereno Municipal Code says about signage: allowable temporary signs (sale/open-house/election/flags), the general 500‑foot prohibition near roads/public places, the scenic‑corridor limitation, and how Planned Development (PD) approvals control signs on PD properties. For exact language and to pull permit forms, consult the cited ordinance sections below. All numeric limits below are drawn from the Monte Sereno code (§ references included).

Key citywide rules (short)

• No sign, billboard, poster, pennant, flag or display unit may be placed within 500 feet of any road/highway/street/public place except as specifically allowed in the sign chapter § 10.13.010 .
• Limited sale/rental signs are allowed in residential zones: non‑illuminated, up to 6 sq ft per sign per street frontage § 10.13.010(A) .
• Open‑house directional portable signs are allowed off‑site with strict small size/height limits (no more than 1 sq ft per face, 4 ft high; one double‑faced sign per corner/private parcel; removed after each open house) § 10.13.010(B) .
• Election signs may be erected without a permit but: not on public property; illumination limited; freestanding/suspended signs limited to 6 sq ft and 3 ft high; must be removed within 6 days after the election § 10.13.020 .
• US and California flags are expressly exempt § 10.13.030 .
• If a property is in a Planned Development (PD) the PD permit may specify exact sign types, sizes, locations and controls that override base zoning rules; once a PD is effectuated the PD provisions prevail § 10.05.047 .
• Lighting used for or on signs must comply with the outdoor‑illumination rules (e.g., directed onto the property and not exceed 1 foot‑candle above ambient at adjacent residential property) § 10.17.030 .

(For context about development standards that interact with sign placement — setbacks, lot coverage, parking and design review — see the Monte Sereno development standards and design review pages linked below. For building‑code sign construction requirements see the California Building Standards Code link.)

District‑by‑district breakdown (how sign rules apply locally)

Note: the sign chapter is largely citywide; the subsections below describe the district purpose/uses and the specific ways Monte Sereno’s sign rules interact with those districts.

R‑1‑8 (Single‑Family Residential)

• Purpose / typical uses: single‑family units (minimum lot area 8,000 sq ft, frontage 70 ft) and related residential accessory uses; accessory dwellings and JADUs are allowed where the lot is residential § 10.05.043: R‑1‑8 uses & standards .
• Key dimensional standards (relevant to sign siting): front setback — single‑story 25 ft, second‑story 30 ft; other side/rear setback rules in the district development standards § 10.05.043(C) .
• Sign implications: the residential sale sign allowance (up to 6 sq ft, non‑illuminated, one per street frontage) applies to properties in R‑1 type districts § 10.13.010(A) . Open‑house directional signs and mailbox/name signs (up to 3 sq ft) are also permitted under the city sign rules § 10.13.010(B–C) . Verify front‑setback measured from official plan lines when siting a sign § 10.12.040 .

RM (Multi‑Family Residential)

• Purpose / typical uses: multifamily units (duplex/triplex allowed), accessory dwelling units and related residential care uses are permitted § 10.05.043 A–B .
• Key dimensional standards: min net lot size per unit 14,520 sq ft, front setback single‑story 25 ft, second‑story 30 ft, side setback single‑story 6 ft, second‑story 10 ft § 10.05.043(C) .
• Sign implications: the same citywide sign prohibitions and exceptions apply (sale signs in residential zones, open‑house signs, mailbox/name signs). For multi‑unit complexes, check PD or site‑development permits for any site‑specific sign program (see PD note below) § 10.13.010 .

P / P‑RM (Public and Public/Residential Multi‑Family Overlay)

• Purpose / typical uses: public uses (community centers, public recreation) plus residential when combined with P uses; overlay adjusts standards for mixed public/residential projects § 10.05.043 & § 10.05.050 .
• Key dimensional standards: front/side/rear setbacks follow the P / P‑RM development standards (front 25 / 30 ft rules for stories) § 10.05.043(C) .
• Sign implications: public‑use sites should not place signs on public property without authorization; election signs are forbidden on public property § 10.13.020(B) . Check overlay rules for site‑specific sign allowances.

Planned Development (PD) District

• Purpose / typical uses: PDs are custom‑designed zoning districts where the PD permit defines permitted uses, development standards and sign regulations for that territory § 10.05.047 .
• Key rule for signs: when a PD permit is implemented it controls sign types/height/area/location — PD provisions prevail over base district sign regulations, and the PD can require exact sign dimensions and placement § 10.05.047(3)(a–e) .
• Practical effect: if a property sits in a PD, do not rely solely on the citywide sign chapter — read the PD permit for sign conditions; the PD can be more permissive or more restrictive.

Quick reference standards table

How signage interacts with other review/standards (practical guidance)

• Check the property's zoning and any PD permit first — PD permits can fully define sign allowances and override § 10.13 defaults § 10.05.047 .
• Confirm whether the street or parcel is inside the State‑designated scenic corridor (Saratoga‑Los Gatos Road / State Route 9). Within the scenic corridor only the narrowly enumerated signs in § 10.13.010(A–C) and existing on‑premise signs are allowed § 10.13.010(D–E) .
• Exterior illumination for signs must meet the outdoor illumination chapter — keep glare below 1 foot‑candle at adjoining residential properties § 10.17.030 .
• If the project needs a site development permit or design review (for example larger commercial signage or signs integrated with a multi‑unit site), sign design may be subject to the Site & Architectural Commission or City Council conditions § 10.08 . See the Monte Sereno design review guidance for process details.
• For sign construction details, electrical work or structural anchorage, coordinate with the local building department and the California Building Standards Code (Title 24) for permit/design requirements — the municipal code explicitly defers technical building/safety requirements where applicable (not a substitute for Title 24 review) (Not found in retrieved materials for procedural interaction; verify with the building department and Title 24).

Relevant internal pages you may need while preparing an application: the city's development standards, parking, design review, overlay district guidance and ADU pages. See: Monte Sereno Development Standards, Monte Sereno Parking, Monte Sereno Design Review, Monte Sereno Overlay Districts, Monte Sereno ADUs, and the state code at California Building Standards Code.

Checklist

• Confirm zoning district for parcel (R‑1‑8, RM, P/RM, PD) and whether a PD permit applies § 10.02.010; § 10.05.047 .
• If PD, obtain and read the PD permit for sign specifics — PD controls signs when effectuated § 10.05.047(3) .
• Confirm whether location falls within the State scenic corridor (Route 9); if so, verify allowed sign types § 10.13.010(D) .
• For sale/rental/open‑house/election/mailbox signs, confirm size, height and removal timing match the limits in § 10.13.010–.020–.030 .
• If any illumination is proposed, ensure lighting complies with Chapter 10.17 (direction, foot‑candle limit, prohibited lamp types) § 10.17.030 .
• If the sign is structural or electrical, confirm building permit and Title 24/California Building Standards Code requirements with the building department (Verify with building official).
• If sign will be on public property or within public right‑of‑way, obtain authorization (open‑house and election signs generally prohibited on public property) § 10.13.010(B); § 10.13.020(B) .
• If the sign is an existing pre‑existing on‑premise sign established prior to the Chapter effective date, confirm amortization/permit timeline under § 10.13.010(E) .

Risks & Ambiguities

Plain‑English summary

Most small residential signs are allowed (for sale, mailbox, limited open‑house and election signs) if they meet the Monte Sereno size/height/time rules; large or illuminated commercial signs, signs on public property, or signs in PD or scenic corridor areas will be controlled by special rules or the PD permit — always check the parcel’s zoning/PD and the specific code sections listed below before installing a sign § 10.13.010–.030; § 10.05.047; § 10.17.030 .
