Oakland Setbacks & Height Limits — Residential Zones

Last updated: Verified:

Fact-checked against Oakland Planning Code Title 17 effective July 21, 2026, and current California ADU law on September 21, 2026.

Oakland's current Planning Code no longer uses the old RD-1 / RD-2 framework shown on the previous version of this page. The current code uses a single RD Detached Unit Residential Zone in Chapter 17.15.

Current RD Zone

Current Table 17.15.03 provides:

Standard RD
Minimum lot width mean 20 ft
Minimum frontage 20 ft
Minimum lot area 2,000 sq ft
Maximum residential density 1–2 units on any legal lot; 3 units on a minimum 3,000-sq-ft lot; 4 units on a minimum 4,000-sq-ft lot
Front setback, lot ≥3,000 sq ft and street-to-setback gradient ≤20% 15 ft
Front setback, gradient >20% 5 ft
Interior side setback 4 ft
Street-side setback 4 ft
Rear setback 10 ft
Maximum wall height, footprint slope ≤20% 30 ft
Maximum pitched-roof height, footprint slope ≤20% 35 ft
Maximum accessory-structure height 15 ft

The previous page's RD-1 20/5/20-ft and RD-2 15/5/15-ft yard table is therefore obsolete.

Smaller Lots Have Separate Setbacks

For lots under 3,000 sq ft, Table 17.15.03 directs users to Table 17.15.04 for reduced setbacks.

Do not apply the 15/4/4/10-ft pattern automatically to every RD lot without checking lot area.

Steep Lots Have Separate Height Rules

The 30-ft wall / 35-ft pitched-roof figures above apply to lots with a footprint slope of 20% or less.

For lots with footprint slope greater than 20%, the code directs users to Table 17.15.06. Oakland hillside property should therefore be checked using the slope-specific table.

FAR and Lot Coverage

For one- and two-unit projects, the current RD table directs users to Table 17.15.05 for maximum FAR and lot coverage.

The previous page's simple 40%/45% lot-coverage claims tied to RD-1/RD-2 have been removed because those old zones no longer describe the current code.

Current Code Publication

Oakland's official Planning Code page states that the current Title 17 PDF is effective July 21, 2026 and notes that the online Municode version may lag behind the City's latest PDF.

Use the City's current PDF when the two sources differ.

California State ADU Law

California State ADU Law is currently codified at Government Code §§66310–66342.

For new-construction ADUs, current state law generally limits required side and rear setbacks to no more than 4 ft. ADU height and unit combinations vary under the current statutory provisions.

See the Oakland ADU rules page for local implementation.

How to Check a Property

  1. Confirm the current zoning district and Height Area in Oakland's zoning map.
  2. If the parcel is RD, use Chapter 17.15 and Tables 17.15.03–17.15.06.
  3. Check lot area before applying the standard RD setback row.
  4. Check footprint slope before applying the ordinary height limits.
  5. Check historic, hillside, wildfire, special-zone, and other mapped controls.
  6. Confirm current-code questions against Oakland's latest official Title 17 PDF.

FAQ

What are the setback requirements in Oakland?
Setbacks vary by zoning district. In RD-1 (Detached Unit Residential), expect a 20 ft front setback, 5 ft interior side setbacks, and a 20 ft rear setback. RD-2 reduces the front and rear to 15 ft. RM-1 (Mixed Housing Type) generally requires 15 ft front, 5 ft side, and 15 ft rear. Corner lots, hillside lots, and substandard lots may have modified requirements — always verify your specific zone on Oakland's zoning map.
What is the maximum building height in Oakland residential zones?
Maximum height is 30 ft in RD-1 and RD-2 zones and 35 ft in RM-1. Height is generally measured from average grade to the highest point of the roof. Hillside properties, the S-7 Preservation Combining Zone, and the Wildfire Prevention District can all impose additional height restrictions.
How is lot coverage calculated in Oakland?
Lot coverage is the percentage of the lot area covered by principal and accessory buildings. Oakland allows up to 40% in RD-1, 45% in RD-2, and 55% in RM-1. Uncovered decks, pools, and driveways are generally excluded, but check Title 17 definitions for your district.
Does state ADU law override Oakland's setback rules?
Yes. Under California ADU law (AB 68, SB 13, AB 881, AB 2221), detached ADUs are entitled to 4 ft side and rear setbacks and up to 16 ft in height (taller in some cases) regardless of the base zone. Oakland cannot impose stricter setbacks on a state-compliant ADU. See Oakland's ADU rules page for details.
