Setbacks

Setbacks are the required distance a structure must sit from the property lines. They differ by zone, and accessory structures and ADUs follow the city’s accessory structure guidelines.

What Livermore requires for an ADU

Livermore’s planning FAQ says both attached and detached ADUs require a permit. ADUs are permitted in all residential zoning districts and must include permanent provisions for living, sleeping, eating, cooking and sanitation on the same parcel as a single-family or multi-family dwelling. Short-term rentals are not permitted in ADUs.

Accessory structures and ADUs must follow the setback requirements in the city’s accessory structure guidelines, and the city publishes ADU standards that cover submittal requirements.

The pre-approved ADU path

Livermore keeps a list of pre-approved ADU plans, and the city says applications using them are reviewed in 7 business days instead of 15 business days for standard applications.

The homeowner pays a flat $1,000 plan review fee to the city, and additional construction and inspection fees still apply and vary with the plan chosen. The flat fee does not include the designer’s fees.

Homeowners must contract with the designer responsible for the plan set, and the city notes that every pre-approved plan still needs site-specific plans, studies and engineering as applicable.

Standard ADU review	15 business days
Pre-approved plan review	7 business days
City plan review fee for pre-approved plans	$1,000 flat
How to start	Online permitting; select Master Plans as the permit type and email the application to permitcenter@livermoreca.gov
Contacts	Planning (925) 960-4450; Permit Center (925) 960-4410

Checking your zoning and setbacks

The city says zoning is checked on its GIS interactive map, which shows the allowed uses and development standards such as height and setbacks. Zoning districts include the residential districts, Planned Development (PD), Planned Unit Development (PUD) and Transect Zones (T3 or T4).

Setbacks depend on the zone, and for PD or PUD properties the city asks you to contact a planner. Fences are limited to 6 feet on the sides and rear and 3 feet in front, with exceptions for corner lots and certain areas.

Other rules that can affect a sale

• Home occupations: allowed under the development code, may need approval from several agencies and require annual renewal. Food businesses need a cottage food operation permit.
• Accessory structures: detached garages, sheds, patio covers and arbors over 120 square feet, or attached to a building, need a building permit.
• Planning timeline: the city says a simple approval could take under a month and a larger project several months.

If the property has an unpermitted unit

Livermore’s pages describe how to permit a new ADU but the sources I read do not describe a Livermore amnesty program, so check with the Permit Center at (925) 960-4410 before assuming an unpermitted unit can be legalized and on what terms.

State law on legalizing certain older ADUs is covered in our Walnut Creek guide, which describes how one nearby city handles it.

For disclosure, California Civil Code section 1102.1 keeps the duty to disclose material facts in an as-is sale, and a late disclosure allows the buyer to cancel within three days of in-person delivery or five days of mailing. See our statewide guide.

Questions to ask before selling a property with an ADU

• Can you produce the permit and final inspection for the unit?
• Is the unit being used as a short-term rental, which Livermore does not allow in ADUs?
• Do accessory structures meet the setbacks in the city’s guidelines?

A cash buyer can purchase the property as it stands, so you do not need to finish permit work first. Our Livermore building permits guide covers the application process.

Tax and disclosure points for a Livermore property with an ADU

Under Proposition 13 a California home is taxed at 1% of taxable value plus voter-approved debt, and the base year value generally changes on a change in ownership or new construction. Ask the Alameda County Assessor how a new or legalized ADU will be treated. See our Prop 13 reassessment guide.

California also requires a natural hazard disclosure covering six zone types, from flood and dam inundation areas to fire, earthquake fault and seismic hazard zones. The seller or the seller’s agent must deliver it, and waiver is void. See our hazard disclosure guide.

Weighing a build against an as-is sale

An ADU adds plan, permit and construction costs before it adds value, and a buyer’s lender may not count it until the final inspection. Pre-approved plans shorten the city’s review from 15 to 7 business days, but design, engineering and construction still take time. A direct cash sale skips that work. Compare both using the net proceeds calculator in our seller closing costs guide.
