Permits in Winnetka
Winnetka is part of the City of Los Angeles, so your ADU or addition is permitted through LADBS under the City of LA zoning code. That means the citywide ADU ordinance applies, and plan check runs through LADBS rather than a local city hall. We file the drawings and carry them through corrections and inspections.
