ADU costs
An ADU in California costs approximately $125 to $300 per square foot, but some can reach as high as $600 per square foot. Your costs will vary depending on unit size, location, lot conditions, building and safety regulations, zoning requirements, and personal preferences like fit and finish.
The main factors that impact ADU construction costs are:
-
ADU Size
-
Construction Type
-
Lot Slope
-
Utilities & Finishing
-
Soft Costs
-
Contingency
ADU Size
Larger ADUs cost more to build but have a lower cost per square foot than smaller ones. This is because larger ADUs spread the total construction cost over more area. To reflect this, our calculator projects higher costs for the initial 500 square feet and less for additional footage.
