Bathroom Remodel · Humboldt County, California
In California, whether a Bathroom Remodel needs a permit depends on the scope of the work.
In California, cosmetic bathroom work needs no permit, but relocating plumbing, adding circuits, venting an exhaust fan to the exterior, or structural changes require a permit; shower waterproofing is inspected with a pan flood test (IRC P2709), and Title 24 energy rules apply to lighting and fans. Confirm which permits your project triggers with Humboldt Building Inspection.
