Last reviewed: July 1, 2026

Overview

This page distills how Brisbane’s Title 17 Zoning ordinance sets the measurable rules that shape projects: setbacks, height, floor area ratio (FAR), lot coverage, lot size/width/depth, and related objective standards. Use it with the city’s zoning map and any mapped overlays to confirm your site’s district. For broader context, see the Brisbane zoning overview, district purposes in Brisbane Zoning, and allowed uses in Brisbane Land Use.

Below you’ll find district-by-district metrics, plus cross‑district rules (setback encroachments, landscaping, objective design standards), and where state overlays like SB 9 and ADU law adjust local numbers.

Citywide development standards that commonly affect projects

  • Objective housing design standards apply to most multi-unit housing and require conformance with all applicable zoning development regs, plus other objective standards; the code points you back to district metrics (e.g., R‑2 at §17.08.040, R‑3 at §17.10.040) and SCRO‑1 at §17.16.040 for projects mapped there .
  • Setback encroachments: Title 17 lists what can project into required yards (eaves, certain windows, decks, etc.) with limits by yard and minimum clearances; consult §17.32.070 for precise allowances .
  • Fences/walls: Exceptions and height nuances vary by district (e.g., additional lattice in R‑1/R‑2/R‑3/R‑BA/NCRO‑2 rear/side yards) per §17.32.050(B) .
  • Landscaping maintenance and performance bonds may be required under §17.32.240–.250 for incomplete site work/required landscaping at occupancy .

District-by-district standards

R-1 Residential District (single-family)

  • Purpose/where it applies: Standard single-family zoning on mapped R‑1 lots citywide; see the zoning map for parcels. Development regs are in §17.06.040 .
  • Typical permitted uses: One single-family dwelling per lot; home occupations; day care homes; ADUs/JADUs (per Chapter 17.43) .
  • Key dimensional standards:
    • Lot area: The minimum 5,000 sf; single-family may also be built on a legal lot under 5,000 sf per §17.06.040(A) and §17.32.100 cross‑reference .
    • Lot width/depth: 50 ft minimum width, 100 ft minimum depth (§17.06.040(C)) .
    • Setbacks (§17.06.040(D)):
      • Front: 15 ft; can reduce to 10 ft on ≥15% slope or to the block-front average where that’s less than 15 ft; garages/carports minimum 10 ft front setback unless the city engineer allows less for safety .
      • Side: 5 ft; may reduce on sub‑50‑ft lots to 10% of lot width but not under 3 ft (or UBC minimum), with 10 ft minimum if the side yard contains a street/alley garage or carport entrance, unless a lesser distance is found safe by the city engineer .
      • Rear: 10 ft .
    • Lot coverage: 40% max (§17.06.040(E)) .
    • FAR: 0.72 max; on lots ≤3,700 sf, up to 200 sf of one covered parking space can be excluded from FAR (§17.06.040(F)) .
    • Height: 28 ft on slopes <20%, 30 ft on slopes ≥20%; within the first 15 ft from the front lot line, overall height limited to 20 ft from finish grade (special garage allowance noted); living area under a permitted elevated garage may not exceed 30 ft from finish grade (§17.06.040(G)) .
    • Facade articulation: Objective wall articulation is required for larger exterior walls (§17.06.040(H)) .
  • Practical: R‑1 has several slope‑ and block‑context exceptions that can materially change the front and side yard design envelope; measure from the correct grade and confirm garage entry conditions early.

R-BA Brisbane Acres Residential District

  • Purpose/where it applies: The Brisbane Acres subarea designated in the General Plan (steep terrain and habitat constraints) (§17.12.010–.020) .
  • Typical permitted uses: One single-family dwelling; home occupations; day care homes; ADUs/JADUs (§17.12.020) .
  • Key dimensional standards (§17.12.040):
    • Lot area: 20,000 sf minimum; single-family allowed on smaller legal lots per §17.01.060 cross‑reference; clustered development/density transfer available under §17.12.050–.055 .
    • Lot width/depth: 110 ft width, 140 ft depth minimums .
    • Setbacks: Front 10 ft; side 10% of lot width (no more than 15 ft, no less than 5 ft), with 10 ft minimum where a garage/carport takes access from the side street/alley; rear 10 ft .
    • Lot coverage: 25% max; FAR: 0.72 max with an absolute cap of 5,500 sf total floor area (§17.12.040(E)–(F)) .
    • Height: Not found in retrieved materials for base R‑BA; see R‑TUO ridgeline limit below and verify with the jurisdiction.
  • Clustered development option (§17.12.055): Allows clustering one single-family per 20,000 sf of site area with at least 40% of the site permanently conserved as habitat; minimum clustered lot size 5,000 sf; requires a city council use permit with habitat and infrastructure findings .

R-TUO Residential Two‑Unit Development Overlay (SB 9 implementation)

  • Where it applies: Overlay on mapped R‑1 and portions of R‑BA (excluding certain protected habitat areas); unless specifically superseded, the base district’s standards still apply (§17.05.020) .
  • What it does (§17.05.070):
    • Units: Up to two primary units per lot and, in some scenarios, up to a total of four units with ADUs/JADUs, subject to the overlay’s matrix and the overall cap (§17.05.070(A)(1)) .
    • Primary unit minimum size: Each primary unit must be allowed at least 800 sf regardless of lot coverage/FAR; above 800 sf, district FAR applies (§17.05.070(A)(2)) .
    • Side/rear setbacks: 4 ft minimum for primary units unless the base district allows less; legal nonconforming walls can be retained/rebuilt in place (§17.05.070(A)(4)) .
    • Height near reduced setbacks: If using the 4‑ft side/rear setbacks, any portion between 4 ft and the district’s normal setback may not exceed 25 ft in height (§17.05.070(A)(5)(a)) .
    • Ridgeline lots in R‑BA: Max primary‑unit height 25 ft unless an exception applies (§17.05.070(A)(5)(b)) .
    • Parking: 1 standard space per primary unit (garages don’t count); exemptions near transit or car‑share apply; driveway sharing may be allowed (§17.05.070(A)(6)) .

R-MHP Mobile Home Park District

  • Where it applies: Parcels mapped R‑MHP.
  • Typical permitted uses: Mobile homes and related accessory/community buildings; home occupations; ADUs per Chapter 17.43 (§17.11.020) .
  • Key dimensional standards (§17.11.040):
    • Park density: Max 1 unit/1,500 sf of park area.
    • Setbacks/coverage: Governed by California Code of Regulations Title 25; local FAR: none; max accessory structure height 20 ft .
  • Note: Title 25 is a state regulation, not the local California Building Standards Code; confirm park‑specific plan compliance.

PAOZ-1 and PAOZ-2 (Planned Area Overlay Zones)

  • Where it applies: Parcels mapped PAOZ‑1/2 (verify with the zoning map).
  • Typical permitted uses: Multi‑family, dwelling groups, accessory structures; single‑family and JADUs allowed in PAOZ‑1 only (§17.27.020) .
  • PAOZ‑1 development regs (§17.27.040):
    • Density: 20–28 du/ac minimum/maximum.

    • Landscaping: 25% lot area minimum; recycling area standards also apply .

ADUs and their effect on coverage, FAR, setbacks, and height

  • District interaction: ADUs generally count toward lot coverage and FAR, except “state‑exempt ADUs” are excluded; attached ADUs follow the district height limit; detached ADUs are capped at 16–18 ft depending on site and transit context (§17.43.040–.060) . State ADU height and setback minimums are further detailed in state guidance (see California ADU law) .
  • Minimum side/rear setbacks for ADUs: 4 ft; certain conversions may have no new setbacks (§17.43.040(G)) .
  • For a full ADU how‑to, see Brisbane ADUs.

Nonconforming and substandard lots

  • Substandard lots: Title 17 contains exceptions for lot area/dimensions/lot lines for substandard lots (§17.32.055); use R‑1 and R‑BA cross‑references and confirm “lot of record” status with the city .
  • Nonconforming uses: Expansion of nonconforming residential uses in R‑1/R‑2/R‑3/R‑BA may be permitted only if the expansion complies with current development standards (FAR, setbacks, height, coverage) and parking (§17.38.030(B)) . See Brisbane Nonconforming Uses.
  • Variances/exceptions: Where strict application creates undue hardship, consult Brisbane Variances and Exceptions.

Checklist

  • Confirm your base district and any overlays on the parcel (R‑TUO, PAOZ, SP‑CRO) in the zoning map and Brisbane Overlay Districts.
  • Verify minimum lot area/width/depth and whether substandard lot exceptions apply (§17.32.055) .
  • Apply district setbacks and check §17.32.070 for allowable projections into the yard (eaves, windows, decks) .
  • Check height—including slope‑based limits and any reduced‑height zones within a front yard hold‑down (R‑1 §17.06.040(G)) and any overlay‑specific caps (R‑TUO, R‑BA ridgeline) .
  • Calculate lot coverage and FAR (apply small‑lot parking exclusion where allowed in R‑1; note R‑BA 5,500‑sf FAR cap) .
  • If adding units via SB 9, apply R‑TUO standards (min 800‑sf primary units; 4‑ft side/rear setbacks; special height limits near reduced setbacks) (§17.05.070) .
  • If adding an ADU/JADU, apply Chapter 17.43 (4‑ft side/rear; height 16–18 ft for detached; how ADUs count toward coverage/FAR) and see Brisbane ADUs .
  • Apply any district landscaping/screening minimums (e.g., Crocker Park 15%, C/P‑U Commercial 5%; see also Brisbane Landscaping and Screening) .
  • Confirm parking and loading standards per Chapter 17.34 (link: Brisbane Parking).
  • Determine if your project triggers a design permit or housing development permit; see Brisbane Design Review and §17.45.010–.030 for objective design standards in housing projects .
  • If expanding a nonconforming residential use, ensure full compliance with current development standards and parking (§17.38.030(B)); see Brisbane Nonconforming Uses .
  • For signage, consult Brisbane Signage. For state overlay effects (density bonuses, SB 9, ADUs), see California housing laws and California ADU law.

Risks & Ambiguities

Issue Why it matters What to verify
R‑1 front/side exceptions Slope and block‑average rules can tighten or relax setbacks Confirm slope percentage and block context; apply §17.06.040(D) precisely
Front yard height hold‑down in R‑1 A 20‑ft cap within first 15 ft can reshape massing at the street Map the 15‑ft depth from the front lot line; see §17.06.040(G)
R‑BA height (base) Not explicitly found in retrieved text “Not found in retrieved materials.” Verify with the jurisdiction
R‑BA clustered development Can unlock yield with habitat conservation but requires council use permit Applicability, conserved‑habitat boundaries, and findings (§17.12.055)
R‑TUO ridgeline height cap (R‑BA) Reduces total buildable volume on some parcels Whether the lot is a mapped ridgeline lot (§17.05.070(A)(5)(b))
PAOZ‑2 metrics Overlay exists but numbers not retrieved “Not found in retrieved materials.” Verify district‑specific regs
SP‑CRO height Height defers to Sierra Point guidelines Which guideline sheet controls max height (§17.18.040(F))
C/P‑U commercial setbacks “N/A” Other objective standards may still control street frontage Access/landscaping/screening and any frontage road dedication conditions (§17.22.030)
ADU exclusions from coverage/FAR “State‑exempt ADUs” don’t count in coverage/FAR Whether your ADU qualifies as state‑exempt (§17.43.040(H)–(I))
R‑2/R‑3 references in objective standards The code points housing projects back to R‑2/R‑3 development regs Specific R‑2 (§17.08.040) and R‑3 (§17.10.040) numbers were not retrieved; verify locally

Plain-English Summary

Brisbane assigns each parcel to a zoning district that sets hard numbers for lot size, setbacks, height, lot coverage, and FAR. In the R‑1 district, expect a 15‑ft front setback (with slope/block exceptions), 5‑ft sides, 10‑ft rear, 40% coverage, 0.72 FAR, and a 28–30 ft height limit with a 20‑ft cap near the front lot line. In R‑BA, lots are much larger (20,000 sf), coverage is lower (25%), and FAR is capped at 0.72 up to 5,500 sf. Overlays like R‑TUO (SB 9) and ADU rules can reduce side/rear setbacks to 4 ft and guarantee space for additional small homes, while commercial/industrial districts (e.g., Crocker Park, TC‑2, C/P‑U) have their own yard, height, and FAR caps. Always layer these with setback encroachment rules and any mapped overlays that add or supersede standards.

Frequently asked questions

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

Typically, one single-family home per lot, subject to R‑1 metrics: minimum 5,000 sf lot, 15 ft front, 5 ft side, 10 ft rear setbacks, 40% coverage, 0.72 FAR, and 28–30 ft height (with a 20‑ft height cap within the first 15 ft of front yard). ADUs/JADUs are allowed per Chapter 17.43 (§17.06.040; §17.43) .

What are the basic setback rules for houses in Brisbane?

In R‑1, the base setbacks are 15 ft front, 5 ft side (with narrow-lot reduction), and 10 ft rear; R‑BA has 10 ft front/rear and a side yard equal to 10% of lot width (5–15 ft). Check §17.32.070 for allowed encroachments (eaves, certain windows, decks) (§17.06.040(D); §17.12.040(D); §17.32.070) .

How tall can my house be in the R-1 district?

Up to 28 ft on slopes under 20% and 30 ft on slopes 20% or more. Within 15 ft of the front lot line, the height is capped at 20 ft (with special allowances for garages detailed in the code) (§17.06.040(G)) .

What does the SB 9 (R‑TUO) overlay change on a single-family lot?

It allows two primary units and, in some cases, up to a total of four units with ADUs/JADUs. It sets 4‑ft side/rear setbacks for primary units, ensures at least 800 sf per primary unit, and caps height at 25 ft in the portion using reduced setbacks; R‑BA ridgeline lots are 25 ft max (§17.05.070) .

Do ADUs count toward FAR and lot coverage in Brisbane?

Generally yes, but “state‑exempt ADUs” are excluded from lot coverage and FAR calculations. Minimum side/rear setbacks are 4 ft, and detached ADUs are limited to 16–18 ft in height depending on conditions (§17.43.040(H)–(J)) .

What are Sierra Point (SP‑CRO) setbacks and height?

Setbacks are 25 ft front; 15/20 ft side (interior/exterior); 20 ft rear for interior lots (15 ft on corners). 40% lot coverage; height and building placement near the mean high tide line must match the Sierra Point combined site/architectural guidelines (§17.18.040) .

I’m in Crocker Park—what’s my envelope?

Minimum site 10,000 sf/100 ft width; yards 25/10/10 ft (front/side/rear); 60% lot coverage; 50 ft height; 2.0 FAR; and 15% landscaping (§17.19.040) .

What if my lot is smaller than the district’s minimum?

Brisbane provides exceptions for substandard lots and “lots of record,” plus some district‑specific small-lot allowances (e.g., R‑1 FAR parking exclusion on ≤3,700‑sf lots). See §17.32.055 and the specific district regs; then verify with the City for parcel‑specific cases .

Do I need a design or housing development permit?

Single‑family projects often proceed without a housing development permit, but multi‑unit projects typically need one and must meet objective design standards. The code outlines applicability in §17.45.010 and the required objective standards in §17.45.030; see Brisbane Design Review too .

Where can I find R‑2 and R‑3 development standards?

The objective standards section points to R‑2 at §17.08.040 and R‑3 at §17.10.040, but specific numbers were not in the retrieved text here. Not found in retrieved materials—verify with the jurisdiction or the published municipal code . ---
