Mountain View — Signage

Q: What sign permits do I need in Mountain View?

If the sign isn't listed as exempt in § 36.36.15 , you must obtain a sign permit approved through the Development Review/design review process; the ordinance makes it unlawful to construct, alter or display a sign that does not comply with Chapter 36. § 36.36.10 .

Q: How is sign area measured in Mountain View?

Sign area is measured by the single rectangular or circular shape that encloses all sign elements (individual letters mounted on a wall are enclosed by one rectangle); multi‑sided signs count all visible sides toward area. § 36.36.65 .

Q: Are sandwich boards (A‑frame signs) allowed?

No — A‑frame or sandwich board signs are expressly prohibited under the city’s general prohibited sign types and are also specifically prohibited within the downtown precise plan area. § 36.36.20 and § 36.36.95 .

Q: My building faces the freeway — can I put a freeway‑oriented sign?

Maybe. Buildings adjacent to freeways with limited visibility from an adjacent public street may be allowed signs oriented toward the freeway, but the sign area still counts against your district’s aggregate limits and must comply with district standards. Verify eligibility and how the area is counted. § 36.36.55 .

Q: What types of signs are exempt from sign permits?

Small, limited signs are exempt (examples: one "open/closed" window sign < 2 sq ft; official flags within size limits; small business information signs; single open‑house signs); exempt signs do not count against aggregate area but may still require building permits for electrical/structural work. § 36.36.15 .

Q: Can the city require a smaller sign than the numeric maximum in the table?

Yes — the ordinance makes the numeric maxima into maximums only, and the zoning administrator may require smaller signs for architectural compatibility and to harmonize with the building and neighborhood. § 36.36.05 .

Q: Are illuminated or neon signs allowed?

Illumination is limited: signs should be illuminated only at the lowest level necessary, directed at the sign or internal to it. Neon/exposed fluorescent signs have a specific height restriction (no part of that sign shall exceed 10 ft above the adjacent street) and are otherwise limited by district rules and downtown restrictions. § 36.36.30(e) and related subsections. § 36.36.17/36.36.12 notes on exposed light.

Q: What if my property is in the downtown precise plan area?

Downtown has its own sign regulations that are generally more restrictive — many sign types are prohibited downtown and signs are generally unlit or only internally/indirectly lit unless specifically approved. Use the downtown rules in § 36.36.60 and § 36.36.95 .

Q: If I change tenants, do nonconforming signs have to be removed?

Yes — the code requires legally established nonconforming signs to be brought into conformance when there is additional development of a site or a change of use/tenant (window signs excepted) and nonconforming signs are subject to the time limits in the nonconforming provisions (which include a five‑year conformance schedule). § 36.36.35 and cross‑reference § 36.06.95 .

Q: Where do I check district specific signage limits?

Look up your zoning district and then consult the district row in § 36.36.55 (Permitted Signs by Zoning District) for aggregate area, building and freestanding sign allowances. If your parcel is covered by a precise plan or overlay, consult that precise plan for its sign provisions. § 36.36.55 and § 36.36.60 .

Overview

This page summarizes what the City of Mountain View's zoning ordinance (Chapter 36) requires for signs: who needs a permit, what types of signs are allowed or prohibited, how sign area and height are measured, and the district‑by‑district standards that control size, location and illumination. For broader context about local land‑use rules and where signage fits in the entitlement process, see the Mountain View zoning & planning overview and the city’s Mountain View Zoning pages. The sign rules are collected in Article XII (Signs) of Chapter 36 and are implemented through the Development Review/design review process. § 36.36 et seq. contains the controlling rules.

Core rules (what the ordinance actually says)

Permit requirement — A sign may not be constructed, altered or displayed except in conformance with the sign chapter; signs require sign permits approved through the development review process unless they are listed as exempt. § 36.36.10.
Purpose and aesthetic test — Signs are regulated to identify establishments while avoiding excessive visual competition and to harmonize with building and neighborhood character; the zoning administrator may reduce allowed maximums for architectural compatibility. § 36.36 and § 36.36.05.
Exempt signs — A limited list of small signs do not require zoning approval and do not count against a site’s aggregate sign area (examples: one "open/closed" window sign < 2 sq ft; certain flags; small business information and open‑house signs). § 36.36.15.
Prohibited signs — A broad set of device types are banned citywide (examples: animated/moving/flashing signs, most banners and pennants (exceptions exist), signs in the public ROW, rooftop signs, signs painted on roofs or fences, A‑frame/sandwich boards). § 36.36.20 and additional downtown prohibitions in § 36.36.95.
General sign regulations — Minimum safety/visibility rules, illumination limited and directed, window sign limits, barber poles and menu‑holder allowances, and rules about readerboards/temporary signs. § 36.36.25, § 36.36.85, § 36.36.90.
Measurement and aggregate area — Sign area is measured by the single rectangular (or circular) shape enclosing all sign elements; multi‑sided signs count all visible sides; aggregate sign area equals the sum of all non‑exempt signs on the property. § 36.36.65.
Findings and review standard — The zoning administrator may approve or conditionally approve signs only after finding the sign complies with the chapter, identifies the business rather than multiple products, is proportional and compatible, and limits illumination among other findings. § 36.36.30.
Enforcement, removal and nonconforming signs — Illegal temporary signs may be removed without notice; illegal permanent signs have a written‑notice process; nonconforming signs must be brought into conformance when a site changes or within five years per the nonconforming schedule. § 36.36.40 and § 36.36.35 (see also § 36.06.95 referenced for the five‑year rule).
Downtown precise plan — The downtown area has its own sign rules (more restrictive, many sign types prohibited and most signs unlit or only indirectly/internal lit) and may supersede district standards in the downtown precise plan area. § 36.36.60 and § 36.36.95.
Signs on freeway‑facing buildings — Buildings adjacent to freeways with limited visibility from a public street may be allowed freeway‑oriented signs, but the area must be counted against the district limits and comply with the applicable district standards. § 36.36.55 (referencing sign area counting; plus related note § 36.36.35 / § 36.36.17 snippets).
Sign programs — For multi‑tenant or multi‑building sites the zoning administrator may require a sign program to establish a common visual theme. § 36.36.10(c).

See the ordinance for fine‑print definitions (what counts as sign area, window sign rules, neon rules, etc.). § 36.36.65 and related subsections contain measurement rules and detailed allowances for window signs and temporary signs.

District‑by‑district breakdown (sign standards tied to zoning districts)

Note: the ordinance attaches maximum sign area and typical allowed sign types per zoning district in the table in § 36.36.55; below I synthesize the sign dimensions and the specific district references. For full land‑use purposes and allowable uses in each district, consult the Mountain View Zoning pages and the district purpose text in Chapter 36 (e.g., 36.14 for commercial districts, 36.20 for industrial).

Each subsection below focuses on the sign rules that apply in that district (purpose and uses are summarized where available in the zoning code; if the purpose text is outside Article XII it is cited separately).

Checklist (what an applicant must satisfy)

Confirm the zoning district for your parcel (see Mountain View Zoning) and check the district row in § 36.36.55 for the numeric limits. § 36.36.55.
Determine whether the sign is exempt under § 36.36.15 (if so, zoning approval not required). § 36.36.15.
If not exempt, prepare a sign permit application and submit through Development Review / design review (per § 36.44.45 rules). § 36.36.10 and § 36.44.45.
Measure sign area per § 36.36.65 and total aggregate signage for the site. § 36.36.65.
Ensure the sign does not fall into the prohibited types list (animated, roof signs, A‑frames, etc.). § 36.36.20 and § 36.36.95 (downtown).
Prepare drawings showing attachment, dimensions, lighting, and materials so the zoning administrator can make the findings in § 36.36.30 (scale, harmony, illumination, public safety). § 36.36.30.
If your site is multi‑tenant, be ready to propose a sign program if requested under § 36.36.10(c). § 36.36.10(c).
Check downtown precise plan rules if the parcel lies in the downtown precise plan area — downtown rules may be more restrictive. § 36.36.60.

Risks & Ambiguities

Issue	Why it matters	What to verify
Architectural compatibility vs. numeric maximums	The ordinance treats stated area/height as maximums but allows the zoning administrator to require smaller signs for compatibility. You can have a permitted numeric area but still be required to reduce the sign. § 36.36.05	Ask the zoning administrator whether the site will be held to the maximums or reduced due to design compatibility; submit elevation/context photos. Verify during development review.
Whether a sign is "exempt" vs. requires building permits	Exempt signs under § 36.36.15 still "may require building permits." The ordinance does not list building permit thresholds for every sign. § 36.36.15.	Confirm with Building Division whether a structural or electrical permit is required (building code issues are Title 24 and outside Article XII). Verify with the city; building‑permit triggers are not fully stated in Article XII.
Downtown precise plan overrides	Downtown rules ban many sign types and impose stricter illumination rules; relying on district table alone can be misleading in downtown. § 36.36.60, § 36.36.95.	If parcel is in downtown, use downtown sign rules as primary standard and confirm whether precise plan sign provisions or an adopted sign program apply.
Nonconforming sign timeline and triggers	Nonconforming signs must be brought into conformance with change of use/tenant or within five years; exact triggering events can be case‑specific. § 36.36.35 and crossref to § 36.06.95.	For an existing sign, verify whether it is legally nonconforming, the date it became nonconforming, and whether proposed changes trigger mandatory removal or upgrade.
Signs oriented to freeway	Freeway‑facing signs are permitted in narrow circumstances but their area still counts against site limits — this can materially reduce allowable street‑facing signage. § 36.36.55 and related notes.	Confirm if the building qualifies (limited visibility from adjacent public street) and get clear direction on how that sign area will be deducted from district allowances.
Variations inside planned community/precise plans	Precise plans may have enforceable sign provisions differing from the base district. § 36.36.55 (note about precise plans) and § 36.50 series.	Review the applicable precise plan and ask the zoning administrator whether site is subject to a precise plan sign standard.

Plain‑English summary

If you want a sign in Mountain View, check whether it’s one of the small exempt types; if not, measure it the way the code requires, confirm the numeric limits for your zoning district (or downtown precise plan), and submit a sign permit through Development Review — the zoning administrator will check size, placement, lighting and design against the ordinance findings and may require a smaller or differently lit sign to protect neighborhood character. § 36.36.10, § 36.36.65, § 36.36.30.

How is sign area measured in Mountain View?

Sign area is measured by the single rectangular or circular shape that encloses all sign elements (individual letters mounted on a wall are enclosed by one rectangle); multi‑sided signs count all visible sides toward area. § 36.36.65.

Are sandwich boards (A‑frame signs) allowed?

No — A‑frame or sandwich board signs are expressly prohibited under the city’s general prohibited sign types and are also specifically prohibited within the downtown precise plan area. § 36.36.20 and § 36.36.95.

My building faces the freeway — can I put a freeway‑oriented sign?

Maybe. Buildings adjacent to freeways with limited visibility from an adjacent public street may be allowed signs oriented toward the freeway, but the sign area still counts against your district’s aggregate limits and must comply with district standards. Verify eligibility and how the area is counted. § 36.36.55.

What types of signs are exempt from sign permits?

Small, limited signs are exempt (examples: one "open/closed" window sign < 2 sq ft; official flags within size limits; small business information signs; single open‑house signs); exempt signs do not count against aggregate area but may still require building permits for electrical/structural work. § 36.36.15.

Can the city require a smaller sign than the numeric maximum in the table?

Yes — the ordinance makes the numeric maxima into maximums only, and the zoning administrator may require smaller signs for architectural compatibility and to harmonize with the building and neighborhood. § 36.36.05.

Are illuminated or neon signs allowed?

Illumination is limited: signs should be illuminated only at the lowest level necessary, directed at the sign or internal to it. Neon/exposed fluorescent signs have a specific height restriction (no part of that sign shall exceed 10 ft above the adjacent street) and are otherwise limited by district rules and downtown restrictions. § 36.36.30(e) and related subsections. § 36.36.17/36.36.12 notes on exposed light.

What if my property is in the downtown precise plan area?

Downtown has its own sign regulations that are generally more restrictive — many sign types are prohibited downtown and signs are generally unlit or only internally/indirectly lit unless specifically approved. Use the downtown rules in § 36.36.60 and § 36.36.95.

If I change tenants, do nonconforming signs have to be removed?

Yes — the code requires legally established nonconforming signs to be brought into conformance when there is additional development of a site or a change of use/tenant (window signs excepted) and nonconforming signs are subject to the time limits in the nonconforming provisions (which include a five‑year conformance schedule). § 36.36.35 and cross‑reference § 36.06.95.

Where do I check district specific signage limits?

Look up your zoning district and then consult the district row in § 36.36.55 (Permitted Signs by Zoning District) for aggregate area, building and freestanding sign allowances. If your parcel is covered by a precise plan or overlay, consult that precise plan for its sign provisions. § 36.36.55 and § 36.36.60.
