  • What is an accessory dwelling unit?
    An ADU (Accessory Dwelling Unit) is a secondary housing unit that can be built on a single-family residential lot. It is also known as a granny flat, backyard cottage, or in-law unit. ADUs may be attached to the primary residence, such as a garage or basement conversion, or they can be detached structures. They offer an innovative and effective option for adding much-needed housing in densely populated areas, and they can also provide rental income or housing for family members.
  • What are the benefits of having an accessory dwelling unit?
    The benefits of having an accessory dwelling unit (ADU) include additional living space, rental income, increased property value, affordable housing, multigenerational living, and sustainable living practices.
  • How do I build an accessory dwelling unit?
    The process of building an accessory dwelling unit (ADU) varies depending on state and local regulations, but generally involves the following steps: Check Zoning and Building Codes: Check local zoning and building codes to determine if building an ADU is allowed on your property. Design: Work with an architect or design professional to create a plan for your ADU that meets local building and zoning requirements. Permits: Obtain the necessary permits from the local government to build the ADU. Construction: Hire a contractor or builder to construct the ADU. Utilities: Connect the ADU to water, sewer, electricity, and gas utilities. Inspection: Have the ADU inspected by the local government to ensure it meets safety, health, and building standards. Occupancy: Once the ADU passes inspection, it can be occupied by tenants or family members. It's important to follow all local regulations and obtain any necessary permits before starting construction on an ADU.
  • How do I get permits for an accessory dwelling unit?
    Getting permits for an accessory dwelling unit (ADU) involves the following steps: Research local zoning and building codes to determine if ADUs are allowed on your property.

Undergo permit review by the local government to ensure the ADU meets safety, health, and building standards. Receive final approval for the ADU permit, which allows construction to begin.
  • How long does it take an ADU and JADU application to get approved?
    Whether or not a local agency has adopted an ordinance, applications to create an ADU or JADU shall be considered and approved ministerially within 60 days from the date the local agency receives a completed application.

For local agencies without an ADU ordinance, maximum unit sizes are 1,200 square feet for a new detached ADU and up to 50 percent of the floor area of the existing primary dwelling for an attached ADU (at least 800 square feet).
  • Can maximum unit sizes exceed 1,200 square feet for ADUs?
