CA AB1166

Amends Government Code Section 65964.1 to require wireless telecommunications facility applications be deemed approved if local governments fail to act within timeframes established by FCC rules (Title 47 CFR Part 1, Subpart U) rather than specific FCC decisions.

Establishes that the approval timeline begins when an applicant takes the first procedural step required by the city or county's regulatory review process.

Requires applicants to provide all required public notices and notify the local government when the reasonable time period has lapsed for the deemed approval to take effect.

Allows cities or counties 30 days after notice of deemed approval to seek judicial review of the provision's application.

Clarifies that wireless telecommunications facility permitting is a matter of statewide concern, not a municipal affair, and exempts applications for placement on fire department facilities from the deemed approval provision.
