Do I need a permit for interior remodeling in Unincorporated Wood County?

It depends. Whether interior remodeling needs a permit in Unincorporated Wood County comes down to the details of your project.

Repairs and maintenance are outside the UDC under SPS 320.05(3); alterations to a UDC-era home must meet the code, and whether a building permit is needed is a local question. The state plumbing and electrical codes apply to all homes regardless of age, even where no building code covers the remodel. As of Sept. 1, 2026, SPS 316.012 requires an electrical permit from the designated inspection agency before installing a new or added electrical service, feeder or branch circuit serving a structure not already covered by an SPS 316 or SPS 320 permit, unless exempted by rule or statute. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time.
