Camarillo FAQ
Do I have to pay impact fees on a Camarillo ADU?
No, if your ADU is under 750 square feet — state law (Gov. Code §65852.2(f)) prohibits impact fees on ADUs below that threshold. ADUs 750 sq ft and larger pay fees proportional to the size of the primary dwelling.
Do I need a separate water and sewer connection for my Camarillo ADU?
Not for an ADU created within an existing single-family home — state law forbids requiring a separate utility connection. New detached ADUs may require separate metering depending on the utility provider.
Ventura FAQ
Will I pay impact fees on a 700 sq ft ADU in Ventura?
No. State law (Gov. Code § 66477.5) prohibits any impact fee on ADUs under 750 sq ft. You will still pay standard plan check and building permit fees.
What if my ADU is 900 sq ft?
The city may charge impact fees, but only in proportion to the primary dwelling — calculated as ADU square footage divided by primary square footage.
Does this include school fees and utility connections?
School impact fees are subject to the same proportionality rule. Utility connection fees that reflect actual labor costs are not 'impact fees' and may still be charged.
