Most major renovations require permits: structural work, plumbing, electrical, layout changes, new kitchens, bathrooms, and exterior modifications. Cosmetic updates like paint or floor refinishing generally don’t require permits, but it’s worth confirming before starting. Permits protect you at resale, prevent fines, and ensure work meets safety standards. Older San Francisco homes have their own quirks, so I guide clients through which projects require permits, which don’t, and which improvements will create the strongest long-term value without creating compliance problems later.
