Question 1

What exactly is an ADU?

Accepted Answer

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. It can be attached to the main house, converted from an existing space, or built as a separate structure. In California, ADUs must include living, sleeping, cooking, and bathroom facilities, making them fully functional homes.

Question 2

Why are ADUs gaining popularity?

Accepted Answer

ADUs are becoming more popular because they increase property value, provide extra living space, and offer rental income potential. Their smaller size and lower cost make them a great alternative to buying a new home. In California, state incentives encourage homeowners to build ADUs, helping to increase housing density without changing neighborhood character.

Question 3

What types of ADUs are allowed in California?

Accepted Answer

Allowed ADU types include detached ADUs, attached ADUs, garage conversions, and Junior ADUs (JADUs), depending on local regulations.

Question 4

Can I build an ADU on my existing property?

Accepted Answer

Most properties with an existing or proposed residential home are eligible to build an ADU, subject to zoning and site requirements.

Question 5

Are there size limits for ADUs?

Accepted Answer

Yes. Size limits vary by city but typically range from 800 to 1,200 square feet.
