Overview

Belvedere regulates land use through its Municipal Code Title 19 Zoning, with districts mapped on the City’s Official Zoning Map and dimensional standards set across several chapters. The code organizes land into single-family, duplex, multifamily, mixed-use, recreation, and open space zones, plus a planned unit development (PUD) overlay that can modify some standards but not density, lot coverage, or height. See the official zoning map instructions and boundary rules in §§19.12.020–.030, and start with the citywide Belvedere zoning & planning overview for context.

How Belvedere’s Zoning Is Organized

  • Official map and boundaries. The “Official Zoning Map of the City of Belvedere,” adopted December 8, 2025, is on file with the City Clerk; it governs each parcel’s base zone. Where boundaries are unclear, §19.12.030 sets tie-breakers (e.g., follow street centerlines; mean high water for land/water lines).
  • Dimensional standards. Lot area/width/frontage, setbacks, lot coverage, floor area ratio (FAR), height, and related rules are primarily in Chapters 19.44, 19.48, 19.52, and 19.56. If you’re designing or siting a project, refer to Belvedere Development Standards.
  • Design review. Nearly all exterior work in residential zones requires design review under Title 20; Title 19 cross-references this repeatedly (e.g., height approvals are subject to Chapter 20.04).
  • Parking. Zone- and use-specific off-street parking applies (e.g., 2 spaces per single-family home in R-1 zones; R-2/R-3 have unit-based ratios). See the R-1 summary (§19.24.060) and R-2/R-3 standards, and the city’s parking page.

Base Districts — District-by-District

Below are Belvedere’s base zoning districts and the key takeaways you’ll actually use to scope a project.

O — Open Space, Scenic

  • Purpose. Preserve natural scenic areas kept essentially unimproved; public use from sunrise to sunset.
  • Typical permitted uses. Enjoyment of scenic beauty; wildlife habitat; gardens/paths; limited outdoor recreation by use permit.
  • Development standards. Set by the Planning Commission through design review on a case-by-case basis (Title 20).
  • Where it applies. Parcels formally designated on the Official Zoning Map.

R — Recreation

  • Purpose. Recognizes park and recreation lands.
  • Typical permitted uses. Beaches, parks, paths, piers, wharves; public buildings and club buildings require a use permit.
  • Development standards. Set per project in the use permit; Commission specifies setbacks, yards, lot coverage, and height.
  • Where it applies. Recreation sites mapped on the Official Zoning Map.

R-1C — Single-Family (Corinthian Island)

  • Purpose and uses. One single-family dwelling per lot, with customary residential accessory uses and ADUs permitted by right; certain community or institutional uses need a use permit.
  • Typical permitted uses. Single-family dwellings; ADUs and JADUs; home offices (with limits); small community care and small family day care; municipal uses.
  • Key dimensional standards.
    • Minimum lot area: 7,500 sq ft; min average width and frontage: 65 ft.
    • Front setback: unique to Corinthian Island—either the street line or 5 ft from the improved street line, whichever is farther from the street centerline.
    • Side setback: 5 ft. Rear setbacks vary by adjacency (e.g., 20 ft abutting a lot; 10 ft abutting a street in R-1C).
    • Lot coverage: 40% covered; 50% total with uncovered decks. FAR: 50% up to 3,500 sq ft max. Height: generally up to 28 ft, with hillside exceptions up to 36 ft if average slope ≥30% and conditions are met.
  • Where it applies. Corinthian Island area on the Official Zoning Map.

R-1L — Single-Family (Belvedere Lagoons)

  • Purpose and uses. Same R-1 permitted uses; lagoon-interface rules apply.
  • Key dimensional standards.
    • Minimum lot area: 7,500 sq ft; width/frontage: 65 ft.
    • Front setback: “all other residential” rule (15 ft; may reduce to 10 ft if ≤25 ft tall within first 40 ft of lot; to 5 ft if ≤15 ft tall within first 40 ft). Side: 5 ft first story, 10 ft second story. Rear: 20 ft abutting a lot; 15 ft where rear abuts water in R-1L.

Height: 22 ft max; FEMA “substantial improvement” changes the measuring point to Base Flood Elevation +1 ft freeboard; a 1-ft height bonus per extra 1 ft of second-story side-yard (to 26 ft) is allowed; never above 29 ft from existing grade.
  • Special lagoon rules. Setbacks measured from water’s edge at summer high-tide if side or rear line is in water; lagoon bulkheads/docks need design review and a BLPOA letter before approval.
  • Where it applies. Lagoon-fronting tracts as mapped; water-edge measurement applies only where the line lies in the water.

R-1W — Single-Family (West Shore)

  • Purpose and uses. Same R-1 permitted uses.

    • Lot coverage: 30% covered; 50% total. FAR: 33% up to 4,850 sq ft max. Height: generally up to 28 ft; hillside exception up to 36 ft if average slope ≥30% and all conditions are met.
  • Where it applies. Larger hillside or estate lots per the Official Zoning Map.

R-2 — Duplex Residential

  • Purpose. Duplex/two-family areas, with objective standards.
  • Typical permitted uses. All R-1 uses; two-family dwellings; supportive/transitional housing; some public uses subject to use permit.

    • Usable open space and parking: see §19.52.140 (R-2 private open space minimum 300 sq ft per unit, with a 3:2 common-space substitution allowed) and R-2/R-3 development tables for parking ratios.
  • Where it applies. As mapped on the Official Zoning Map.

R-3 — Multifamily Residential

  • Purpose. Multifamily areas with objective, ministerial standards where state law applies.
  • Typical permitted uses. Multifamily dwellings; all R-1 uses; supportive/transitional housing; certain civic uses with use permit.
  • Key dimensional standards.

  • Typical permitted uses. Retail and personal services; banks; business services; multifamily (standalone or in mixed-use); and related uses; emergency shelters subject to specific provisions.
  • Key development standards (Table 19.41-A).
    • Max height: 3 stories up to 45 ft, with upper-story stepbacks on street-facing elevations. Front/Street-side setbacks: 10 ft baseline; 20 ft for garages. Residential share of floor area must be ≥50% in mixed-use. Open space: 400 sq ft/unit (≥200 sq ft private). Parking: 1 space/unit (may be common). Lot coverage: 50%; max FAR of 1.0 for structures.
  • Where it applies. Mapped MU corridor along Tiburon Boulevard.

Overlay Districts

  • PUD Overlay (Planned Unit Development). May be applied only over R-2, R-3, or R-3C base zones and only to sites totaling ≥1 acre. It does not change permitted uses of the base zone unless a conditional use permit is approved. Density, lot coverage, and height may not be changed by a PUD; however, minimum lot size, setbacks, and parking can be adjusted through the PUD permit and rezoning process. See application/permit procedures in Chapter 19.87 and the city’s Overlay Districts.
  • Note on R-3C. The code identifies an R-3C (Multiple Dwelling—Belvedere Cove) base zone for PUD eligibility; specific R-3C standards were not contained in the retrieved excerpts. Not found in retrieved materials.

Selected Standards At-A-Glance

The values below are the ones that most often drive feasibility. Always confirm parcel-specific conditions, height measurement basis, and any overlay or view/slope constraints.

Zone Min Lot Area Front/Side/Rear Setbacks (high-level) Lot Coverage (covered / total) FAR cap Height (base, key exceptions) Code Reference
R-1C 7,500 sq ft Front: special Corinthian rule; Side: 5 ft; Rear: 20 ft abutting lot; 10 ft abutting street in R-1C; water/alley 10 ft 40% / 50% 50% (≤3,500 sf) 28 ft; up to 36 ft on ≥30% slope w/ conditions
R-1L 7,500 sq ft Front: 15/10/5 ft based on height; Side: 5 ft first, 10 ft second story; Rear: 20 ft abutting lot; 15 ft where rear abuts water (R-1L) 40% / 50%; up to 50% covered if ≤15 ft high 50% (≤4,000 sf) 22 ft; FEMA BFE+1 ft for substantial improvements; 1-ft bonus to 26 ft; never >29 ft from grade
R-1W 7,500 sq ft Front: 15/10/5 ft based on height; Side: 5 ft first, 10 ft second story; Rear per §19.48.170 40% / 50% 40% (≤4,240 sf) 22 ft; +1 ft per extra 1 ft second-story side-yard to 26 ft; measured from top of curb
R-15 15,000 sq ft Front: 15 ft (10 ft if low height near front); Side: 10 ft or 10% width, min 5 ft; Rear per §19.48.170 30% / 50% 33% (≤4,850 sf) 28 ft; up to 36 ft on ≥30% slope w/ conditions
R-2 6,000 sq ft Side: 5 ft new/10 ft second story; front/rear follow city rules unless conditioned 40% (50% if adjacent open water) / 60% total n/a (FAR caps apply mainly in R-1/R-15) 22 ft; FEMA BFE+1 ft if substantial improvement; +1 ft to 26 ft via side-yard bonus
R-3 6,000 sq ft Side: 5/10/15 ft by bldg height 40% (50% if adjacent open water) / 60% total n/a 36 ft; Beach Rd incentive max 38 ft (affordable + consolidation)
MU per §19.41 Front/Street-side: 10 ft; interior side: 5 ft (10 ft if abutting res.); rears vary; 75% of street-facing elevation above second story steps back 5 ft 50% (site); total FAR ≤1.0 1.0 total floor area 3 stories up to 45 ft, with stepback triggers

Notes:

  • Usable open space per unit in R-2/R-3 is defined in §19.52.140 with specific minimums and substitution rules; R-2/R-3 objective standards also summarize open space/parking. Where table summaries and Chapter 19.52 differ, verify with staff.
  • In all residential zones, certain equipment may intrude into yards subject to conditions (e.g., low-height AC condensers in side yards; generators under specific slope/noise conditions).

How to Apply the Map and Standards Together

  • Find your base zone on the Official Zoning Map, then apply the corresponding district rules above. Where the mapped line seems ambiguous, use §19.12.030’s interpretation criteria; when in doubt, the more restrictive adjoining zone may govern.
  • Check for overlays (e.g., PUD) and for parcel conditions (slope ≥30%; lagoon frontage; floodplain) that change how height is measured or where setbacks are taken.
  • Confirm whether your proposal triggers objective standards in R-2/R-3 or MU, or discretionary design review with neighborhood compatibility findings elsewhere.

Checklist

  • Confirm your parcel’s base zone on the Official Zoning Map and any overlay (PUD).
  • Verify minimum lot area/width/frontage for the zone (esp. R-15 vs. R-1).
  • Apply front/side/rear setbacks, including special R-1C front rule and lagoon water-edge measurement in R-1L.
  • Calculate lot coverage and, where applicable, FAR limits and exceptions.
  • Determine height and how to measure it (existing grade, front curb in R-1W, or BFE+1 ft if “substantial improvement” in R-1L/R-2).
  • If duplex/multifamily/MU: apply objective standards (parking, open space, massing, stepbacks).
  • Confirm off-street parking, including unit-based ratios in R-2/R-3.
  • Verify if State Density Bonus or R-3 incentives apply; use ministerial track where required by state law references in Title 19.
  • Determine if design review is required (it almost always is in residential zones).
  • If nonconforming or seeking relief, see Nonconforming Uses and Variances and Exceptions. Verify with the jurisdiction.

Risks & Ambiguities

Issue Why it matters What to verify
R-2/R-3 open space numbers differ between objective standards tables and §19.52.140 Different sections summarize open space; project feasibility may hinge on required square footage and whether common space may substitute Ask Planning which section governs for your submittal; cite §19.52.140 and 19.28 development tables in your application package
Height measurement basis varies by zone/condition R-1W measures from curb; R-1L/R-2 may measure from BFE+1 ft if “substantial improvement”; others from existing grade Confirm the measurement trigger and datum in early design; reference §§19.56.040, .100 and FEMA “substantial improvement” definitions
Front setback “ladder” depends on building height within front 40 ft Getting this wrong can force a redesign at hearing Document height sections within 40 ft of front line per §§19.48.040–.060 and show compliant sections/elevations
Hillside height exception in R-1C/R-15 Up to 36 ft allowed on steep lots, but only with multiple conditions Confirm average slope calc and the 28-ft average height cap in §19.56.070; prepare a slope analysis exhibit
Lagoon properties (R-1L) use water-edge setbacks and need BLPOA letter Triggers different setback baseline and extra approval Survey summer high-tide line; obtain BLPOA permission before design review per §§19.48.010(D), 19.48.190(N)
PUD overlay cannot change density/coverage/height Don’t overpromise entitlements in R-2/R-3 PUD concepts Limit PUD requests to allowed topics (e.g., setbacks, parking) per §19.42.050

Plain-English Summary

Most Belvedere lots are single-family in one of four zones—R-1C (Corinthian Island), R-1L (Lagoons), R-1W (West Shore), and R-15 (large-lot). Each sets basic rules for setbacks, lot coverage, floor area caps, and height, with important twists: lagoon lots measure some setbacks from the water; some steep lots can go taller; West Shore height is measured from the curb, not the ground; and duplex/multifamily/MU areas follow objective standards for height, massing, open space, and parking. Nearly all projects need design review, so get your zone and measurement rules right before you draw.

Frequently asked questions

What can I build on an R-1 lot in Belvedere?

A single-family home with typical residential accessory uses is allowed by right, and ADUs/JADUs are permitted. Some institutional or community uses require a conditional use permit. Check §19.24.020 for permitted uses and §19.24.030 for uses needing permits.

What are Belvedere’s standard setbacks for single-family homes?

Front setbacks vary by zone and by the building’s height within the first 40 feet of the lot; side and rear setbacks also vary by zone. For example, R-1L/R-1W side yards are 5 ft (first story) and 10 ft (second story); R-1C fronts follow a special Corinthian Island rule. See §§19.48.040–.060, .120–.150, and .170.

How tall can I build in Belvedere’s single-family zones?

Generally, up to 28 ft in R-1C and R-15, 22 ft in R-1W and R-1L, with specific exceptions (e.g., hillside up to 36 ft in R-1C/R-15; a side-yard “bonus” to 26 ft in R-1W/R-1L/R-2). Height may be measured from curb (R-1W) or from Base Flood Elevation +1 ft (R-1L/R-2 with “substantial improvements”). See §§19.56.030–.080 and .100.

I’m on the Lagoon—how are my setbacks measured?

In R-1L, when a side or rear property line is in the water, setbacks are measured from the water’s edge at summer high-tide. Bulkheads/docks require design review and a BLPOA permission letter before approval. See §§19.48.010(D) and 19.48.190(N).

What are the rules in duplex (R-2) and multifamily (R-3) zones?

R-2 allows two-family dwellings; R-3 allows multifamily. Objective standards set parking, open space, height, and massing; open space minimums are in §19.52.140 and summarized in Chapter 19.28 tables. Incentive programs can increase density/height in certain R-3 cases.

Where can I find the zoning for my lot and what if the zone line is unclear?

Use the Official Zoning Map kept by the City Clerk. If a boundary is uncertain, §19.12.030 sets interpretation rules (e.g., follow street centerlines or mean high water). In doubts, the more restrictive zone may govern until clarified.

Does Belvedere have a mixed-use zone?

Yes. The MU zone along Tiburon Boulevard allows a mix of residential and commercial with objective, form-based standards for height, setbacks, stepbacks, and open space. See Chapter 19.41 and Table 19.41-A.

Can a PUD overlay change my height or density?

No. A PUD overlay cannot change density, lot coverage, or building height; it can adjust items like minimum lot size, setbacks, and parking in R-2/R-3/R-3C areas (≥1 acre). See §19.42.050.

Do I need design review?

Almost always for exterior work in residential zones. Height decisions explicitly require compliance with Chapter 20.04. Check Title 20 and §19.56.010’s cross-reference.

Are there FAR caps for single-family homes?

Yes. R-1C: 50% to 3,500 sq ft; R-1L: 50% to 4,000 sq ft; R-1W: 40% to 4,240 sq ft; R-15: 33% to 4,850 sq ft. Limited exceptions are possible under §19.52.120 with findings.
