Accessory Dwelling Units - ADUs

What is an ADU?

An Accessory Dwelling Unit (ADU) is a self-contained living unit that is usually smaller than the main home on the same property. It contains a kitchen, bathroom, and a place to sleep. They can be attached to the main home or a separate detached building. They can also take the form of a Junior Accessory Dwelling Unit (JADU), which is a unit up to 500 square feet and are converted from any existing floor space.

Constructing high-quality ADUs that meet local design standards and respect community character can be a substantial investment. In August 2020, the Town launched a Garden Cottage Program, intended to defray some of these costs by offering a selection of pre-designed ADU building plans (detached units only) that can be downloaded free-of-charge.

The program offers a selection of pre-approved, permit-ready ADU building plans that can be downloaded free-of-charge. Because these ADU plans have been pre-plan checked, they are eligible for expedited processing and lower building permit fees.

   

NOTE: If an accessory dwelling unit or junior accessory dwelling unit is rented it shall be rented for terms longer than thirty (30) days, per the Danville Municipal Code.

New Program Provides Rebates for ADU Construction

Cities across California are ramping up efforts to encourage the production of accessory dwelling units (ADUs) to help address the housing crisis. The Senate District 7 ADU Accelerator Program, piloted by Senator Steve Glazer, will be composed of 15 cities in the East Bay of the San Francisco Bay Area, including Danville.

The program will be administered by the California Department of Housing and Community Development for the purpose of advancing or “accelerating” the production of 350 ADUs through a series of programs. This program provides individual rebates of up to $7,500 to property owners for new ADU units and up to $15,000 for new ADU units that are deed restricted to low-income households (minimum of 20 years.) As the purpose of the program is to encourage the construction of smaller ADU units, there will be no rebates for units over 1,000 square feet.
