When a homeowner contemplates having a kitchen remodel done, this question will need to be answered first. The answer will depend on the type of remodeling that gets conducted and what regulations your jurisdiction places on contractors. If the work required modification of your systems, i.e. electrical, plumbing, and mechanical plan for a permit. However, replacing cabinets, countertops, and backsplash does not require permits in most Northern California Jurisdictions. The exception is the city of Davis, where a permit is required for installing a sink. Make sure to enquire with your local building department if you are unsure.
