Redding ADU rules

Redding caps new ADUs at 1,000 sq ft under Section 18.43.140 of its zoning code, below the 1,200 sq ft many California cities allow. The city runs a Pre-Approved ADU Program with ready-to-permit plans, and short-term rentals under 30 days are not allowed. Many lots sit near wildfire-prone terrain, so fire-hardened construction can add cost.

Rules that apply in every California city are summarized in our California ADU law guide. See all California cities or compare every city side by side.
