What This Table Means:
Before building an ADU, your property value increases slowly.
After building an ADU, your property value increases much faster. This is because adding an ADU (a small additional living space) makes your home more valuable, especially over time.
- Important to Know:
How much your property value increases can depend on the city in California where you live. In cities like Los Angeles or San Francisco, adding an ADU can increase your home’s value more than in other areas with less demand for housing. - Rental Income Opportunities
In high-demand cities like Los Angeles and San Diego, ADUs can generate $1,500-$3,000 monthly in rental income. This makes it a lucrative investment, especially in competitive rental markets.

How to Calculate ADU Permit Fees for Your Municipality
Costs for ADU permits include base fees, size-based charges, and impact fees. Here’s a basic formula:
Permit Cost = Base Fee + (Square Footage x Fee per sq. ft.) + Impact Fees
Example:
- For a 500 sq. ft. ADU in Los Angeles:
$3,000 (Base Fee) + (500 sq. ft. x $5) + $1,500 (Impact Fees) = $6,500 Total
