Frequently Asked Questions
Will adding an ADU increase my property taxes?
In most jurisdictions, adding an ADU triggers a "blended" supplemental tax assessment on the newly constructed improvements only, rather than reassessing your entire primary home at current market prices.
Can I finance an ADU with my home equity?
Yes. Fixed-rate HELOCs, cash-out refinances, and construction-to-permanent renovation loans are standard financing mechanisms. Many lenders allow projected future ADU rental income ($1,550 – $2,400/mo) to assist with loan qualification.
