Living in Tarzana
Tarzana is a Los Angeles neighborhood in the San Fernando Valley, sitting with Encino in the Encino-Tarzana Community Plan Area. Municipal land-use regulation, zoning, permits, inspections and fire service are City of Los Angeles matters for Tarzana addresses; there is no City of Tarzana and no unincorporated Tarzana government.
The packet's boundary caution is specific: Tarzana is a community label rather than a Census place or municipal jurisdiction with one authoritative boundary, and council districts should not be used as proof a property is in Tarzana, since district lines change and do not match neighborhood or plan boundaries.
For anything parcel-shaped, the community plan's official maps set the policy frame while parcel-level zoning and entitlement questions still require the City's own records. The neighborhood's south-of-Ventura-Boulevard hillside streets sit against the Santa Monica Mountains, where hillside regulations add a layer worth checking before planning any addition.
