Navigating Zoning Laws for ADU in California

Accessory Dwelling Units (ADUs) are becoming super popular in California. These small, separate living spaces also called granny flats or in-law suites are a great way to add extra housing to a property. But before you start building, you must understand California’s zoning and building permits. Knowing the rules will save you time, money, and headaches! This blog will shed some light on Zoning and Building Permits in California and the basic concept of an Accessory Dwelling Unit (ADU).

What is an ADU?

An Accessory Dwelling Unit (ADU) is a smaller, self-contained home on the same property as a main house. It can be attached, detached, or even built over a garage. These units have everything a regular home has, including a kitchen, bathroom, and living space. ADUs are great for renting out, housing family members, or just creating extra space.

There are many reasons why people are adding ADUs to their properties:

Extra Income – Renting out an ADU can help cover mortgage payments.

Housing for Family – Perfect for aging parents, adult children, or guests.

Increase Property Value – Homes with ADUs often sell for more.

Help Solve Housing Shortages – California needs more homes, and ADUs help!
