What should developers know about Brentwood zoning?
Brentwood's zoning map is unusual for the depth of its planned-development framework. The city carries 83 zoning districts in total, and the dominant pattern is a long sequence of numbered Planned Development zones (PD-1 through the high twenties and beyond) rather than conventional R-1 or R-2 base zones. The largest single districts on record are PD-20 at roughly 610 acres, PD-18 at about 430 acres, PD-27 at around 426 acres, and the Priority Area 1 (PA-1) designation near 374 acres - meaning a developer's first question on almost any growth parcel here is which PD applies and what that specific ordinance permits.
This structure tells you a lot about how Brentwood grew: as a fast-expanding East Contra Costa community, it entitled large tracts through tailored Planned Development zones, each with its own permitted uses, density, and design standards. Conventional commercial land is comparatively thin - Neighborhood Commercial (C-1), General Commercial (C-2), Thoroughfare Commercial (C-3), and the Administrative Professional Office (CO) zone are modest in acreage - while the Downtown (DT) district at about 80 acres and the Brentwood Boulevard Specific Plan (BBSP) at roughly 260 acres concentrate the mixed-use and corridor-revitalization opportunity.
For acquisition and feasibility, the takeaway is that base-zone shorthand will not get you far in Brentwood. Because the planned-development zones govern so much of the land, entitlements, allowable product, and density are defined parcel-by-parcel in the adopting PD documents. The recorded building controls cover FAR, density, coverage, lot width, height, and all setbacks, but the binding numbers live in each PD ordinance and in the BBSP and Downtown plans. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.

Brentwood zoning: frequently asked questions
Why does Brentwood have so many Planned Development zones?
Brentwood entitled much of its rapid suburban growth through individually adopted Planned Development districts - PD-1 through the high twenties and beyond - rather than relying on a few standard residential base zones. The largest, PD-20, covers roughly 610 acres. Each PD sets its own permitted uses, density, and design standards, so the controlling rules for a site are found in its specific PD ordinance.
Where is the best opportunity for mixed-use or downtown development in Brentwood?
The Downtown (DT) district covers about 80 acres and the Brentwood Boulevard Specific Plan (BBSP) spans roughly 260 acres - these are the city's primary corridors for mixed-use, infill, and revitalization product. They concentrate the walkable and higher-intensity opportunity that the surrounding planned-development tracts do not. Review the DT standards and the BBSP document for permitted intensities.
How do I find out what I can build on a specific Brentwood parcel?
Identify the parcel's zoning designation first, then pull the governing document - for most growth land that means a numbered Planned Development ordinance or the Brentwood Boulevard Specific Plan, not the generic base code. Those documents define permitted uses, density, and design requirements. Treat the zoning label as a pointer to the controlling plan rather than the full answer.
Is there much commercial or retail-zoned land in Brentwood?
Conventional commercial zoning is relatively limited. The Neighborhood Commercial (C-1), General Commercial (C-2), Thoroughfare Commercial (C-3), and Administrative Professional Office (CO) districts are modest in acreage compared to the residential planned-development tracts. Buyers chasing retail or office sites should focus on those commercial zones plus the mixed-use opportunity within the Downtown and Brentwood Boulevard plan areas.
Do California's SB-9 and ADU laws apply to Brentwood's single-family parcels?
State housing statutes apply citywide regardless of the local label, but the practical effect depends on the underlying designation - many residential parcels here sit inside Planned Development zones with their own standards. ADU and lot-split provisions generally reach qualifying single-family land, while planned-development design rules may shape siting. Confirm the parcel's PD ordinance and Brentwood's local implementation before assuming a split or unit is feasible.
