## Frequently Asked Questions
### What is the consequence if a California city fails to act on an ADU permit within 60 days?
Under California Government Code § 66314, if the local agency does not approve or deny the permit application within 60 days of receiving a completed application, the application is deemed approved as a matter of law.
### Can a Homeowners Association (HOA) ban ADU construction in California?
No. Civil Code § 4751 renders void and unenforceable any HOA covenant, condition, or restriction (CC&R) that effectively prohibits or unreasonably restricts ADU or JADU development.
