Overview

Mountain View’s zoning ordinance (Chapter 36) establishes several overlay or combining districts that layer additional rules on top of a parcel’s base zone to respond to local neighborhood character, environmental constraints, or plan-level objectives. Overlays do not replace the underlying zone but add or modify standards (for example, height limits, special design rules, or village‑center rules) and are mapped as suffixes to the base district (e.g., R1‑H1S, R3‑SD) § 36.26.65 . Confirm the overlay applicable to a parcel on the City zoning map and the community development department’s records; see Mountain View Zoning for the overall district framework.

Note: where the ordinance requires project-level review, that review follows the City's development/design review process — see Mountain View Design Review — and must also meet the city's Development Standards and related requirements (setbacks, parking, landscaping). The overlay sections specifically cited below are in Chapter 36 of the City Code (zoning) and are the controlling local law for overlays § 36.26.65–36.26.95 .

How to read this page

  • Each overlay below is presented exactly as the code organizes them: the Height Limitation (-H), Neighborhood Design (-ND), Special Design (-SD), and Village Center (VC).
  • For terms you’ll often need (parking, development standards, ADUs, design review, building code) the first natural mention is linked to the City pages referenced in the ordinance: Mountain View Parking, Mountain View Development Standards, Mountain View ADUs, Mountain View Design Review, and the California Building Standards Code. Use those links for procedural or technical handouts; the ordinance text below supplies the legal requirements and code citations.

Overlay districts — district-by-district

Height Limitation (-H) — § 36.26.75

  • Purpose: The -H overlay is used where neighborhood characteristics justify a height limit different from the base zone (for example to preserve single‑story character or view lines) § 36.26.75 .
  • Typical permitted uses: Uses remain those of the underlying base zone; the overlay only adjusts the maximum height permitted (it does not change allowable uses) § 36.26.75 .
  • Key dimensional standards:
    • Height is expressed either in stories or feet appended to the overlay (examples: ‑H1S = one‑story maximum; ‑H25 = 25‑foot maximum) § 36.26.75.c.1–2 .
    • Minimum area for applying an -H overlay must be a definable geographic unit (block, tract, or street face) § 36.26.75.b .
  • Where it applies: Any zone in the city can be combined with -H (commonly applied to residential zones such as R1, R2, R3) — check the zoning map for the exact suffix on a parcel § 36.26.75 .

Practical note: Height measured in stories or feet on the zoning map controls; if you need a higher building than the mapped -H allows you must pursue a map amendment (zoning amendment) per Sec. 36.52.35 (rezoning process) and/or a variance — verify with the zoning administrator.

Neighborhood Design (-ND) — § 36.26.80

  • Purpose: The -ND overlay preserves or enhances discrete neighborhood characteristics through special design standards targeted to that neighborhood § 36.26.80.a–c .
  • Typical permitted uses: Underlying zone uses remain; -ND imposes additional or alternative design standards rather than wholesale use changes § 36.26.80.c–d .
  • Key standards and process:
    • The overlay is applied only to a definable geographic unit (block(s), tract, or street face) § 36.26.80.b .
    • Where the city council adopts special design standards for the neighborhood, those standards apply in addition to (or where in conflict, control over) other ordinance provisions § 36.26.80.d.1 .
    • For new single‑family houses subject to an -ND that regulates multiple special standards, owners must comply with at least half of the applicable standards (a local compromise provision) § 36.26.80.d.1 .
    • All development in an -ND is subject to the City’s development review procedures § 36.26.80.d.2 ; see Mountain View Design Review for process details.
  • Where it applies: Used where residents and the City adopted neighborhood standards; check the zoning map and the ordinance or overlay plan that accompanied the -ND rezoning.

Practical note: Remodels may only trigger the special standards for the portion remodeled (not necessarily the entire home) — review the specific -ND standards that were adopted for the neighborhood to determine applicability § 36.26.80.d.1 .

Special Design (-SD) — § 36.26.85 (and special design permit rules at § 36.50)

  • Purpose: The -SD combining district signals that a site needs tailored development criteria because of proximity to environmental hazards (noise, air pollution), freeway adjacency, unusual size/shape/topography, or other constraints § 36.26.85.a .
  • Typical permitted uses: The principal, accessory and permitted uses of the underlying base zone apply unless the council limits specific hazardous uses. In short, uses follow the underlying zone but may be restricted where hazardous or incompatible § 36.26.85.d .
  • Key dimensional/design standards and process:
    • The city may adopt a set of development guidelines for the SD area that include special setbacks, sound/pollution barriers (walls/berms), window orientation, landscaping buffers, site planning, and other physical requirements designed to mitigate the identified constraints § 36.26.85.e.1–7 .
    • A special design permit is required prior to development in the -SD district (except crop/tree farming) and the permit must detail permitted uses and map/draw the permitted areas § 36.26.85.f; § 36.50.05–25 .
    • The special design permit process is integrated with the city’s development review requirements; findings must demonstrate the design responds to the constraints identified at the time of the SD rezoning § 36.50.05–25 .
  • Where it applies: Applied by zoning amendment to defined parcels where the conditions in § 36.26.85.a exist; the environmental planning commission and city council must find that one or more of the specified characteristics apply when adopting -SD § 36.26.85.c .

Practical note: Because -SD may change setbacks, buffering, or siting, check the SD development guidelines adopted with the rezoning (these are the operative rules used by staff during design review and special design permit evaluation). Those design criteria drive how the site deals with parking (see Mountain View Parking), landscaping (see Mountain View Landscaping and Screening), and building placement.

Village Center (VC) — § 36.26.95

  • Purpose: The VC is a floating village‑center district intended to implement the El Camino Real precise plan’s village‑center growth, transit‑supportive design, pedestrian focus, and public‑benefit expectations § 36.26.95.a .
  • Typical permitted uses: Mixed residential, commercial and civic uses consistent with the base zone and the El Camino Real precise plan; VC is applied to support higher‑intensity, transit‑oriented development where appropriate § 36.26.95.a–c .
  • Key dimensional/standards:
    • Can only be applied to sites identified as village center in the El Camino Real precise plan § 36.26.95.b.1 .
    • Minimum project area: 60,000 sq ft (net) unless parcels are combined into an integrated development § 36.26.95.b.2 .
    • Floor area ratio (FAR) and height allowances follow the Tier structure described in the El Camino Real precise plan; Tier 2 intensities (the highest intensities) require VC zoning § 36.26.95.c–d .
    • VC zoning is applied via a zoning amendment and projects within VC are subject to planned community permit procedures and the El Camino Real precise plan’s development standards (setbacks, parking, open area, etc.) § 36.26.95.c–e .
  • Where it applies: Only in locations identified in the El Camino Real precise plan; VC is not a citywide blanket overlay and is used selectively through rezoning § 36.26.95.a–b .

Practical note: VC projects must obtain a planned community permit and meet precise plan standards; the VC rezoning itself carries public‑benefit expectations that the city council weighs as part of the rezoning action.

Transit (-T) district — § 36.26.90 (REPEALED)

  • The ordinance formerly included a Transit (-T) overlay, but § 36.26.90 was repealed by Ord. No. 22.19 (Dec. 10, 2019). The editor’s note in the code marks this repeal as part of the current Chapter 36 text; Transit (-T) is not in force as a codified overlay at § 36.26.90 (repealed) . Verify with the City for any new transit‑oriented overlay policies or plan areas.

Quick reference table — decision‑relevant items

Overlay Decision‑critical standard / permit Typical effect on uses Code Reference
-H (Height Limitation) Height limited by stories or feet as shown on map; minimum area requirement for application Does not change permitted uses; caps building height (e.g., ‑H1S, ‑H25) § 36.26.75
-ND (Neighborhood Design) Adopted neighborhood design standards override/conflict with other provisions; development review required May require façade, setback, or landscape treatments specific to a neighborhood § 36.26.80
-SD (Special Design) Special design permit required; council/adopted development criteria (setbacks, barriers, orientation, landscaping) Uses follow underlying zone but may be limited for hazardous adjacencies; permits tailor standards § 36.26.85; § 36.50.05–25
VC (Village Center) Applied via zoning amendment; minimum 60,000 sq ft site; planned community permit and El Camino Real precise plan standards Enables Tier 2 intensities under the El Camino Real precise plan (mixed‑use, transit‑oriented) § 36.26.95

Checklist

  • Confirm the parcel’s base zone and any overlay suffix on the official zoning map (zoning map/clerks record); overlays are mapped as suffixes to the base district § 36.04; § 36.26.65 .
  • If the parcel shows an -H, confirm the mapped story/foot limit (e.g., ‑H2S, ‑H25) and design your building to that maximum § 36.26.75 .
  • If the parcel is in an -ND, obtain and review the neighborhood’s adopted special design standards and anticipate development review § 36.26.80 ; see Mountain View Development Standards for related dimensional rules.
  • If the parcel is -SD, assemble an SD‑level design package showing how the project responds to the constraints cited at rezoning (setbacks, berms, orientation, landscaping) and apply for a special design permit per § 36.50 § 36.26.85; § 36.50.05–25 .
  • If VC is being considered, verify that the site is identified in the El Camino Real precise plan, that net site area ≥ 60,000 sq ft, and that planned community permit and Tier process rules are understood § 36.26.95 .
  • For all overlays, confirm how overlay rules interact with parking and other site standards — parking rules remain applicable unless the overlay explicitly modifies them (see Mountain View Parking; overlay sections reference development review and project‑level standards) § 36.26.80–85; § 36.26.95 .
  • Remember to comply with applicable construction and fire code requirements (California Building Standards Code) at building permit stage — overlays do not eliminate Title 24 compliance.

Risks & Ambiguities

Issue Why it matters What to verify
Mapping vs. text differences Overlay restrictions (height in feet vs. stories) are shown on the zoning map and control project design Confirm exact overlay suffix on the City zoning map and the zoning administrator’s interpretation § 36.04; § 36.26.75
SD development criteria not published with rezoning Project approval depends on the SD guidelines adopted with the rezoning; absence of clear guidelines creates uncertainty Request the SD ordinance and adopted development guidelines from Community Development; verify the specific constraints identified at rezoning § 36.26.85.c–e
VC public‑benefit expectations at rezoning VC rezoning requires public benefits as part of the rezoning; that influences project feasibility and entitlement conditions Review the rezoning ordinance and staff reports for required public benefits; verify Tier and planned community permit expectations § 36.26.95.b–e
Transit (-T) status § 36.26.90 was repealed; assumptions about a Transit overlay may be outdated Confirm current City policy for transit‑oriented overlays or plan areas; do not rely on a repealed § 36.26.90 (repeal note)
Interaction with ADU/Accessory rules Overlays may alter setbacks or siting, which affects allowable ADU placement Verify whether the overlay's development criteria change underlying setback/coverage rules that ADUs rely on; ADU specifics are in Sec. 36.12.85 (see Mountain View ADUs) § 36.26.85.d–e; § 36.12.85

Plain‑English summary

If your Mountain View property has an overlay (suffix like -H, -ND, -SD, or VC), the overlay adds special rules on top of the base zoning: ‑H caps building height exactly as the map shows, ‑ND applies neighborhood design rules adopted for that block or tract, ‑SD requires a special design permit and tailored design criteria to handle hazards or odd site conditions, and VC allows higher village‑center intensities only where the El Camino Real plan and rezoning authorize them — check the exact overlay on the zoning map and the cited code sections for what applies § 36.26.65–36.26.95 .

Frequently asked questions

What does a “‑H” overlay mean for my single‑family lot?

A ‑H overlay imposes a mapped, fixed height limit expressed either in stories (e.g., ‑H1S, ‑H2S) or feet (e.g., ‑H25). It does not change what uses are allowed on the lot — only the maximum height allowed — and the overlay applies only where the zoning map shows the suffix § 36.26.75 .

If my house is in a Neighborhood Design (‑ND) overlay, how will that affect an addition?

If your lot is in an -ND, adopted neighborhood standards apply to new development and (for remodels) to the remodeled portion only; if multiple standards exist, a new house need only meet at least half of the standards adopted for that ND § 36.26.80.d.1–2 . Expect development review for the project § 36.26.80.d.2 .

What triggers a Special Design (‑SD) permit and what does it require?

A special design permit is required for new uses, new structures, or significant modifications within an ‑SD district (except for crop/tree farming). The permit must show how the project responds to the environmental/site constraints identified at rezoning (setbacks, barriers, orientation, landscaping, etc.) and is reviewed through the City’s development review/Special Design permit process § 36.26.85.f; § 36.50.05–25 .

Can overlays change parking or setback rules?

Yes — an overlay (especially ‑SD or ‑ND) can adopt special development criteria that modify or supplement standard setbacks, site layout, or parking arrangements. However, unless the overlay specifically changes a standard, parking and setbacks from the base zone and the City’s development standards still apply. Always check the overlay’s adopted guidelines and the base zone rules; see Mountain View Parking and Mountain View Development Standards § 36.26.80–85 .

What is the Village Center (VC) overlay and where does it apply?

The VC is a floating overlay used only where the El Camino Real precise plan identifies village centers; it allows higher Tier intensities (including Tier 2) and is only applied through a rezoning that meets minimum site area (net 60,000 sq ft) and public‑benefit expectations; projects also require a planned community permit and precise plan compliance § 36.26.95 .

Is there still a Transit (‑T) overlay in the code?

No. § 36.26.90 (Transit -T) was repealed by Ord. No. 22.19 (editor’s note indicates repeal). Do not rely on a Transit overlay in current Chapter 36; verify current City transit‑oriented policies separately with staff (repeal note) .

Will being in an SD or ND overlay stop me from building an ADU?

Not automatically. ADUs remain subject to the underlying zone’s allowance and the ADU statute in the code (see Sec. 36.12.85), but an overlay that changes setbacks, coverage, or design requirements may affect where and how an ADU can be sited — verify overlay development guidelines for setback/coverage changes before final design § 36.26.85.d–e; § 36.12.85 .

If overlay text and the zoning map disagree, which controls?

Overlay height limits and suffixes are shown on the official zoning map and the code directs the map and chapter to be used together; where interpretation is needed, the zoning administrator is authorized to determine applicability — contact the Community Development Department for a formal interpretation § 36.04; § 36.02.30 .

Who approves exceptions or modifications to overlay rules?

If an overlay requires a special design permit or planned community permit, the zoning administrator, environmental planning commission or city council may act depending on the permit type and review level; detailed permit procedures and required findings are in the development review and special design permit sections § 36.50; § 36.44.45–70 .
