Thousand Oaks FAQ
Do I have to pay impact fees on a Thousand Oaks ADU?
No, if your ADU is under 750 square feet — state law (Gov. Code §65852.2(f)) prohibits any impact fees on ADUs below that threshold. ADUs 750 sq ft and larger pay fees only in proportion to the size of the primary dwelling.
Do I need a new water or sewer connection for my Thousand Oaks ADU?
Not for an ADU created within an existing single-family home — state law forbids requiring a separate utility connection in that case. A new detached ADU may require separate metering or capacity fees depending on the utility provider and existing service.
