Cost to build a adu
The average cost to build an ADU is $100,000. This figure will vary depending on the size of your property and location of the home.
In most cases, building an ADU in Los Angeles or San Diego will cost anywhere between $75,000 to $125,000. Here are some factors that affect the cost:
Size: The average size of an ADU in California is 600 sq. ft., but some can be as big as 1,500 sq. ft. Thus, the larger your property is, the higher your costs will be.
Location: If you’re planning to build an ADU on a hillside or in a mountainous area, expect higher costs because these areas are more expensive to build on than flat land.
Zoning Laws: Zoning laws vary from city to city and even neighborhood to neighborhood within a city. You should contact your local planning department for more information about what kind of permits you need and how much they will cost before starting construction on your home.

Costs vary widely depending on the size, location and features of your home. The average cost of building an ADU (accessory dwelling unit) is $250,000. But if you are looking to save money by doing most of the construction yourself, it could cost less than half that amount! Homeowners can also reduce their costs by using recycled or salvaged materials and energy-efficient appliances and lighting fixtures.
In addition to the initial construction costs, there are other factors that can affect the overall price tag for adding a granny flat or accessory dwelling unit:
Permitting: Permits typically range from $1,500-$5,000 depending on whether they’re issued by your city or county government. If you don’t have any existing structures on your property and want to build an ADU from scratch, then you’ll likely need two separate permits — one for the main house and one for the accessory dwelling unit (ADU).
