Help homeowners estimate project budgets and get closer to building an ADU

The ADU Calculator is an easy-to-use online tool that gives homeowners the estimates they need to move forward while reducing questions about potential costs at the permit counter, including construction costs, fees, taxes, rents, loan payback periods, and return on investment. Estimates are based on local rules, fees, and real-world construction costs and rents to help homeowners understand how choices may affect their project budget and investment over time.
