Bradbury Zoning and ADU Guide for Homeowners

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team.

Bradbury has five zones (R-7,500, R-20,000, A-1, A-2 and A-5), a monthly Planning Commission, and a city design guideline that has long allowed one accessory living unit per lot, but the guideline’s accessory-unit rules are dated 1995 and state ADU law has changed since. This guide explains how a Bradbury development application moves through the Planning Department, what the city’s design guidelines say about guest houses and accessory living units, and how to treat those older numbers next to current state law.

The city’s current ADU standards were not published on the pages we could read, so confirm with the City Planner before you rely on any figure.

How a development application works

The city’s Planning page says Bradbury contracts with a City Planner who oversees development applications until the Planning Commission approves them and they are ready for the Building Department. The Planning Department also administers the zoning code and design guidelines and serves as staff liaison to the Planning Commission. The City Planner’s office is open Tuesday and Wednesday from 8:30 to 11:00 a.m. at City Hall.

Application forms are available at City Hall or on the city’s website. Applications are submitted to City Hall with three sets of plans and the filing fee from the planning fee schedule.

Once the application is complete, the planner reviews the plans, prepares a staff report and recommendation for the Planning Commission, and the city says that usually takes about a month.

The Commission meets once a month, and minor reviews do not have to go to the Commission and may move faster. After Commission approval, plans go to plan check; see our Bradbury building permits guide.

Bradbury’s five zones

The city lists five zones: R-7,500, R-20,000, A-1, A-2 and A-5. If you know your zone, the city says you can look up permitted uses, required front, side and rear yard setbacks and height limits online.

For new homes and major additions or remodels, the city strongly recommends reviewing its Design Guidelines, and in some cases owners also need to work with a homeowners association.

The guidelines list required lot areas of 7,500 square feet, 20,000 square feet, one acre, two acres and five acres for the five zones, and larger setbacks for bigger parcels and steep slopes.

Accessory living units in the 1995 design guidelines

The city’s design guidelines, dated August 1995, allow guest houses with cooking and bathroom facilities and space for sleeping, and say one accessory living unit is permitted on any lot in each zone.

The listed maximum sizes are 1,200 square feet in R-7,500 and R-20,000, 1,500 square feet in the one-acre estate zone, 2,000 square feet in the two-acre zone and 2,500 square feet in the five-acre zone.

Guest houses are allowed only on residential lots already developed with a single-family home, may not have a separate address or separate utility meters, and need at least one additional on-site parking space reachable from a shared driveway.

The owner or master lessor must occupy either the main house or the guest house.

The guidelines also say lots of at least two acres must set every dwelling, including accessory structures, back at least 100 feet from all lot lines. Findings for approval include that the unit fits the lot and neighborhood, does not overload parking, traffic or utilities, and does not cost neighbors privacy or views. Treat these as historical city standards, not a current ADU checklist.

State ADU law and the older city rules

California’s ADU law limits what cities can require, and many local ordinances have been rewritten since 1995.

California HCD’s review of Bradbury’s draft 2022 to 2029 housing element noted that, based on a cursory review, the city’s ADU ordinance might need revision to comply with state ADU law under Government Code section 65852.2.

We could not read the city’s current ADU ordinance, so the guest house figures above may not match what Planning applies today.

As general state law, ADUs are also entitled to reduced side and rear setbacks and to a ministerial review timeline, which the city’s pages do not list.

Ask the City Planner which standards apply to your lot, and get the answer in writing, especially in a city where the entire area is a very high fire hazard severity zone and the fire code can shape what can be built.

Fire zone and your plans

Every Bradbury project, including a guest house or ADU, must meet the fire-hazard construction requirements the Building Department applies citywide, in Chapters 7-A and 15 of the 2022 California Building Code and the 2023 Los Angeles County Fire Code. New buildings and some additions also need Los Angeles County Fire Department approval before the city issues the permit. Budget time and money for that review if you are legalizing an older guest house.

State ADU law and Bradbury

California’s ADU statute, Government Code section 66314 and following, sets a floor that every city must follow, and local ordinances fill in the details.

The state requires ministerial review within 60 days of a complete application, bars a city from requiring more than a limited set of standards, and generally allows an ADU or conversion inside existing space without added setbacks.

The California Department of Housing and Community Development (HCD) publishes a handbook and keeps a list of the state requirements. Because state law changes often, treat the city’s current ordinance and handout as the final word on size, height, parking and fees for your lot.

ADUs, garage conversions and selling a Bradbury house

Many older homes have a converted garage or a backyard unit built without permits. Buyers and lenders ask about them, and California sellers generally disclose known unpermitted work. Our guide to selling as-is with unpermitted work explains the rules, and our Prop 13 guide explains how new construction can affect property tax. Before you list:

• Check city records for permits on any ADU, conversion or addition.
• Ask Planning whether the structure could qualify under current rules.
• Estimate plans, fees and corrections needed to legalize it.
• Compare that with selling as-is and letting a cash buyer take on the legalization.

Questions to ask Planning before you design

• Does my lot and zone allow an ADU, a junior ADU, or both?
• Is a pre-approved or pre-reviewed ADU plan available?
• What are the current impact, utility and school fees for the size I am considering?
• Can my existing garage or accessory structure be converted without changing its footprint?
• Are there fire, slope, easement or utility constraints on my lot?

Junior ADUs and garage conversions in more detail

State law treats a junior ADU as a unit of up to 500 square feet created inside the walls of an existing or proposed single-family home, with an efficiency kitchen and a recorded restriction that keeps it from being sold apart from the house.

A garage conversion is a different path: the unit replaces the garage, and state law generally does not require the city to demand replacement parking. Both are common sources of unpermitted space in older Bradbury neighborhoods, which is why buyers’ agents and appraisers ask for the permit record.

If a conversion was done without a permit, the usual fix is to submit as-built drawings, pay the fees and pass inspection, which can take months and cost real money.

Fees, utilities and property tax

State law limits the impact fees a city can charge on smaller ADUs and on conversions of existing space, and it limits when a separate utility connection can be required.

Larger new units can still carry impact fees, school fees and water or sewer connection charges, so ask for an itemized estimate before you commit to plans. New construction is generally reassessed for property tax under Prop 13, which means an ADU can raise the bill for the whole property. Our Prop 13 guide explains how reassessment works.

Why ADUs matter for resale

A permitted ADU can add rental income and appeal for some buyers, but an unpermitted one can complicate financing and appraisal. Lenders typically want permitted living area, and an appraiser may not count unpermitted space.

Because an ADU generally cannot be sold separately from the main home, its value comes through the sale of the whole property.

If you inherited a house with an old backyard unit, or bought one with a converted garage, check what the city has on file before you decide how to sell. Our probate home sale guide covers inherited property.
