Do I need a permit?

Construction that requires a building permit includes, but is not limited to:

  • New buildings
  • Additions that increase the physical dimensions of a building including decks.
  • Alterations to the building structure, cost shall include market labor value, or alterations to the building’s heating, electrical or plumbing systems.
  • Alteration of plumbing, venting, electrical or gas supply systems
  • Any electrical wiring for new construction or remodeling
  • Any plumbing for new construction or remodeling
  • Storage sheds and storage buildings


The following construction activities shall NOT require a building permit:

  • Re-siding, re-roofing, and finishing of interior surfaces, installation of cabinetry, and repairs which are deemed minor by the Building Inspector. Notwithstanding this section, however, a permit accompanied by structural load-bearing calculations shall be required for re-roofing a building if the proposed re-roofing would constitute a third, or more, layer of roofing.
  • Normal repairs of HVAC, plumbing, and electrical equipment or systems.


WHEN IN DOUBT, PLEASE CALL AND CHECK BEFORE STARTING A PROJECT. AVOID BEING RED-TAGGED, AND FRUSTRATING DELAYS. These guidelines are for your benefit to speed you through the permitting process as easily and speedily as possible.

WHAT NEEDS PERMITTING/WHAT DOES NOT

If your residents and contractors have specific questions about what needs permitting and what does not, or whether it is the town, county or GEC who requires permits, we could work with you on verbiage for your website to make that clear for them.  I am attaching a website link for one of the communities we serve that may generate some ideas:  https://www.portagewi.gov/building-permits-and-inspections.
