Whittier ADU planning / Start with facts

Additional living space can support family, guests, or a future rental. But a floor plan alone does not prove a project is feasible. Understand the city's plans and your parcel questions first.
General planning information, not a permit approval or construction estimate.

A starting point, not automatic approval.
The City offers four preapproved detached ADU floor plans in Craftsman, Spanish, and Traditional architectural styles. The preapproved plans cannot be modified. Each project still needs site-specific review and applicable permit approvals.
