Mountain View — Land Use

Q: What are Mountain View setback requirements for single‑family (R‑1) properties?

Setbacks and related site standards for R1 are in the R1 Zone Development Standards table at § 36.10.25 ; minimum lot area, frontage and the FAR formula are listed there as well. See § 36.10.25 for front/side/rear setback rules and exceptions (also check § 36.14.75 for certain exceptions) .

Q: How are commercial uses regulated in Mountain View zones?

Commercial uses are listed in the Commercial uses table (see § 36.14.020 ) and the commercial districts (CN, CO, CRA, CS) have district‑specific special standards in § 36.14.030 and related subsections — check the table to see whether your proposed commercial use is P , CUP , or not allowed in that district .

Q: Can I put retail or a small café inside an ML or MM (industrial) area?

Yes — but ML specifically allows limited employee‑serving restaurants/retail/services only if the use is ancillary to the primary industrial use, does not exceed 3,000 sq ft , is sited away from loading/noise areas and meets parking and hazardous materials restrictions (see § 36.20.15(a)(1) ) .

Overview

This page summarizes what the City of Mountain View's zoning ordinance (Chapter 36) actually says about allowed land uses, district purposes, and the most decision‑relevant development limits. It focuses strictly on the zoning/land‑use rules: permitted vs. conditional uses, district purposes, and key dimensional rules — not building code, health or housing law. For the city's zoning framework and maps see the Mountain View zoning & planning overview and the list of zoning districts in § 36.04 . Where the ordinance refers to tables for permitted uses, this page points to those specific provisions (residential use tables, commercial use tables, industrial land‑use charts).

Note: first mentions of linked procedural topics are linked inline — see parking, development standards, design review, overlay districts, ADUs, and the California Building Standards Code.

How Mountain View controls land use (core rules)

Districts are established and mapped in § 36.04; each district has an expressed purpose and its own permitted/conditional use lists and development standards (see § 36.04) .
What is allowed in each district is shown on the land‑use/permit tables (residential: § 36.10.05; commercial: § 36.14.020; industrial: § 36.20.05) — uses listed as P, CUP, TUP or blank are respectively permitted, conditional, temporary, or not allowed .
Uses not listed on the tables are presumptively not allowed; the zoning administrator resolves ambiguities under § 36.06.40 (procedures for interpretation) — do not assume "similar" uses are automatically allowed without a text amendment or CUP where the code requires it .
Conditional use permits (CUPs) are available only for the uses specifically listed as conditional in the applicable district and are decided under § 36.48 (including findings in § 36.48.25) .

District‑by‑district breakdown (purpose, typical permitted uses, key standards, where it applies)

Notes: each district name below is the Mountain View map symbol (bolded); the ordinance text and the land‑use tables cited are the controlling source. For whether a parcel actually carries a district or overlay, check the official zoning map (see § 36.04) .

R1 — Residential — Single‑Family (see § 36.10.10 and § 36.10.25)

Purpose: intended for detached single‑family dwellings and dual urban opportunity developments consistent with low‑density General Plan land use .
Typical permitted uses: single‑family dwellings, accessory uses such as small accessory structures, and ADUs per the ADU rules (see § 36.12.60–36.12.120; ADU rules summarized at Mountain View ADUs) .
Key development standards (highly decision‑relevant): minimum lot area (interior) 6,000 sq ft, (corner) 7,000 sq ft; minimum street frontage 35 ft; FAR is a formula (FAR = 0.50 - (0.00001 × Lot Area); see § 36.10.25) and specific setbacks and site coverage limits apply (see § 36.10.25) .
Where it applies: mapped R1 parcels (suffixes like R1‑8 indicate minimum lot area on map) — see § 36.04 for mapping rules .

R2 — Residential — One‑ and Two‑Family (see § 36.10.40 and § 36.10.50)

Purpose: duplexes, small‑scale townhouse/rowhouse forms and two‑unit configurations compatible with medium‑low density General Plan designations .
Typical permitted uses: single‑ and two‑family dwellings, accessory units, and limited accessory uses; other uses require CUP or PUD per the residential tables (§ 36.10.05) .
Key standards: R2 height limit is usually 30 ft. / 2 stories; site coverage, setbacks and parking follow the R2 tables and Article X parking rules (see § 36.10.50 and Article X) .

R3 — Residential — Multiple‑Family (see § 36.10.60 and related tables)

Purpose: apartments, condominiums and townhomes for medium to higher density housing; specific subcategories (e.g., R3‑2) set density caps .
Typical uses: multi‑family dwellings, accessory residential uses, minor institutional uses where allowed by the table (§ 36.10.05) .
Key standards: site coverage commonly 35% (40% in R3‑D); open area minimum 55% (with private open space minima), height generally up to 45 ft. (and specific wall‑plate limits) — see § 36.10.75 and related development tables for setbacks, parking and open space calculations .

R4 — Residential — High‑density multiple‑family (see § 36.12)

Purpose: highest‑density residential districts; standards and design guidance differ from R3 (see § 36.12) .
Typical uses: multi‑family housing projects, subject to the development standards, density limits and design review.

RMH — Mobile Home Park (see § 36.12.15)

Purpose: mobile home parks with shared recreational facilities; mobile home park permits (MHPP) govern changes and expansion (see § 36.48.45) .

CN / CO / CS / CRA — Commercial zones (see § 36.14.010 and the Uses that are permitted in Commercial Zones table § 36.14.020)

Purposes: neighborhood commercial (CN), office (CO), service/commercial (CS), and corridor commercial/residential (CRA) with district‑specific limits and special standards (see § 36.14.010 et seq.) .
Typical permitted uses: retail, personal and professional services, restaurants (subject to special limits in neighborhood districts), offices (office intensity limits exist in CN/CS), and residential where allowed in CRA per special mixed‑use standards .
Key standards: commercial development standards (setbacks, street frontage, landscaping) are collected under § 36.14.030; see the commercial uses table § 36.14.020 for P/CUP/TUP status by use .

ML — Limited Industrial / Administrative, Research and Limited Industrial (see § 36.20.15 / § 36.20.25)

Purpose: campus‑like research, administrative facilities and light industrial that are non‑nuisance in character .
Typical permitted uses (special ML rules): wholesale, warehousing, data centers (within enclosed buildings), and restaurants/retail/services ancillary to primary industrial uses when limited to 3,000 sq ft total and meeting screening/parking/location rules; accessory outside storage limited to 4% of lot and must be screened (see § 36.20.15) .
Key standards: ML specifics are in § 36.20.15 and ML development standards sections; highly sensitive uses and child‑care are restricted and may require CUPs and special noticing in certain ML locations .

MM — General Industrial (see § 36.20.35)

Purpose: heavier industrial uses with protections for air/water quality and nearby residential areas .
Typical uses: manufacturing, warehousing, data centers and other industrial uses as listed on the industrial land‑use chart § 36.20.05; some uses conditionally permitted with CUP and design mitigation (e.g., drive‑throughs, religious institutions, child‑care under strict criteria) .
Key standards: MM standards address setbacks, landscaping buffers (e.g., 7 ft high masonry walls between public parking and residential), FAR caps for various industrial uses, and a proximity height rule (no structure to exceed 50 ft within 200 ft of any R district in some cases) — see the MM development standards and § 36.20.35 for full details .

P — Planned Community (see § 36.22 and precise plans § 36.50.60)

Purpose: areas governed by an adopted precise plan that supersedes some underlying district rules; precise plans can list provisional uses and unique standards (see § 36.50.75 and § 36.50.55 findings) .
Typical approach: land use and development standards are set by the precise plan and implemented by PUD/planned community permits; check the applicable precise plan before assuming underlying district rules apply .

A — Agricultural, PF — Public Facility, F — Flood Plain, U — Interim

Each special‑purpose district has its own stated purpose and lists of permitted/conditional uses (see § 36.24 for A and PF, § 36.26 for F and U) — for recently annexed lands the U interim zone prohibits new structures and limits temporary uses (see § 36.26.60) .

Overlay districts — -H, -ND, -SD, -VC (see § 36.26.65 et seq.)

Overlays modify the primary district rules (height limits, neighborhood design standards, special design review) and are appended as suffixes (e.g., R1‑H1S) — the overlay procedures and purposes are in § 36.26.65–36.26.95 .

Practical guidance / synthesis (plain‑English interpretation)

Start at the table for your district: the city separates where a use is simply allowed (P), where it needs a conditional use permit (CUP), or is only temporary (TUP). See the residential/commercial/industrial tables at § 36.10.05, § 36.14.020, and § 36.20.05 — uses not listed are generally not permitted without a text amendment or special finding .
Expect accessory commercial in industrial districts to be tightly limited (example: ML allows small employee‑serving retail up to 3,000 sq ft and with parking equal to the primary use) — see § 36.20.15 .
Many approvals require design or development review; review criteria for design review are in the development review divisions (see § 36.44.70 for findings) — anticipate conditions addressing circulation, landscaping and screening . If you are changing or reducing parking, see the parking reduction procedure § 36.32.65 and exemptions § 36.32.67 (some EV and bedroom‑addition changes have their own process) — consult the city's parking rules early in project design (Mountain View Parking) .

Checklist (what an applicant must satisfy under Chapter 36)

Confirm the parcel's mapped zoning and any overlay(s) (see § 36.04) .
Determine whether the proposed use is listed as P, CUP, TUP, or not allowed in the relevant district table (§ 36.10.05, § 36.14.020, § 36.20.05) .
If a CUP is required, prepare the CUP application and supporting materials addressing the findings in § 36.48.25 (compatibility, general plan consistency, CEQA, etc.) .
Verify dimensional standards (lot area, setbacks, FAR, height) in the specific district section (e.g., § 36.10.25 for R1) and any overlay modification § 36.26.xx .
Complete required parking and loading calculations per Article X and request any reductions per § 36.32.65 (or use exemptions in § 36.32.67) — include shared parking agreements or evidence if relying on shared parking .
Prepare landscaping/screening consistent with district standards and Article XI (landscaping) — see development standards and ML/MM buffer rules for industrial adjacency requirements .
If the project is subject to design review or in an overlay (e.g., -ND, -SD), include design documents and responses to the findings in § 36.44.70 and overlay sections § 36.26.65–36.26.95 .
Check for nonconforming use/structure rules if the site currently hosts a nonconforming use (see § 36.06.60–36.06.80) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Use not listed on district table	Chapter 36 treats unlisted uses as not allowed — assuming similarity risks denial	Verify under § 36.06.40 with the zoning administrator whether the use can be classified or requires a text amendment; cite § 36.06.40
Parcel‑specific overlays or precise plans	Overlays and precise plans can override underlying standards (e.g., VC or ND)	Check the official zoning map and any precise plan language before applying; see § 36.26.65 and § 36.50.75
Interpretation of “ancillary” uses (industrial zones)	ML allows limited ancillary retail under strict criteria — ambiguity on scale/location causes disputes	Rely on the specific ML provision (ancillary retail ≤ 3,000 sq ft and parking equal to primary use) — see § 36.20.15(a)(1)
Height/adjacency rules near R districts	Industrial height limits may be reduced near residential areas (e.g., 50 ft within 200 ft)	Verify the applicable MM/ML development standard for the site; proximity rules are location‑dependent — see industrial development standards (e.g., § 36.20.35)
Nonconforming uses	Existing nonconforming uses have time‑limits and reuse/expansion limits	Confirm continuing use rules and whether a CUP or amortization applies; see § 36.06.60–36.06.80

Plain‑English Summary

Mountain View's zoning code (Chapter 36) organizes the city by mapped zoning districts and overlay suffixes; each district's permitted, conditional, and accessory uses are listed in district‑specific tables and are strictly enforced — if your use isn’t on the table, it’s likely not allowed unless you get a CUP or the city amends the code (§ 36.10.05; § 36.14.020; § 36.20.05; § 36.06.40) .

Frequently asked questions

What can I build on an R‑1 lot in Mountain View?

You can build uses listed as permitted in the R1 district table (primarily a single‑family dwelling plus allowed accessory uses and ADUs). Dimensional rules (lot area, frontage, setbacks and FAR formula) are in § 36.10.25 and minimum frontage in § 36.10.20; if a proposed use is not on the R1 table, it is not allowed unless the zoning administrator or City Council approves a reclassification or CUP per § 36.06.40 and § 36.48 .

What are Mountain View setback requirements for single‑family (R‑1) properties?

Setbacks and related site standards for R1 are in the R1 Zone Development Standards table at § 36.10.25; minimum lot area, frontage and the FAR formula are listed there as well. See § 36.10.25 for front/side/rear setback rules and exceptions (also check § 36.14.75 for certain exceptions) .

Do I need design review in Mountain View?

If your project triggers items listed in the development review process (e.g., new structures, major remodels, changes within overlay districts, PUDs, or projects in precise plan areas), design review or development review findings apply — see § 36.44.45 and the development review findings in § 36.44.70; planned community and precise plan projects have additional procedures in § 36.50.55 and § 36.50.75 .

Are accessory dwelling units (ADUs) treated differently under zoning?

ADUs and junior ADUs are addressed as zoning exceptions/exemptions from some zoning permit requirements; the code directs ADU design and compliance to specific sections (see § 36.12.60–36.12.120 in Chapter 36) and the City has an ADU page with summaries — the zoning ordinance exempts certain ADU permit triggers but still requires compliance with the ADU rules and building code (see § 36.06.50(a)) .

How are commercial uses regulated in Mountain View zones?

Commercial uses are listed in the Commercial uses table (see § 36.14.020) and the commercial districts (CN, CO, CRA, CS) have district‑specific special standards in § 36.14.030 and related subsections — check the table to see whether your proposed commercial use is P, CUP, or not allowed in that district .

Can I put retail or a small café inside an ML or MM (industrial) area?

Yes — but ML specifically allows limited employee‑serving restaurants/retail/services only if the use is ancillary to the primary industrial use, does not exceed 3,000 sq ft, is sited away from loading/noise areas and meets parking and hazardous materials restrictions (see § 36.20.15(a)(1)) .

What if my use isn’t explicitly listed in the use table?

The ordinance treats unlisted uses as not allowed unless the zoning administrator determines an allowable classification under § 36.06.40 (procedures for interpretation) or the City adopts a text amendment. Do not assume a "similar" use is permitted without a code determination or CUP where the code requires one .

Are there parking reduction procedures I can use?

Yes. The zoning administrator may grant parking reductions under § 36.32.65 following the CUP procedure; some reductions (EV charger installations; limited bedroom additions in existing multi‑family units) have specific exemptions under § 36.32.67 — review Article X and the referenced sections early in your project planning .

Does the precise plan or PUD change allowed uses?

Yes. Where a P (planned community) district has an adopted precise plan, that precise plan governs land uses and can list provisional uses and specific standards; see § 36.50.55 and § 36.50.75 — planned community permits require findings consistent with the precise plan and the General Plan .

What are the rules for nonconforming uses?

Existing nonconforming uses and structures may continue under the rules in § 36.06.60–36.06.80, but there are limits on continuation, expansion and re‑establishment (including amortization periods/conditions). Verify the nonconforming status and allowed changes with the zoning administrator before relying on continued use rights .
