CITY-SPECIFIC SUMMARY
What Windsor actually says
Windsor’s published permit rules, in plain English:
Windsor says building permits are required for new construction, additions, alterations, renovations, relocations and many repairs.
The city's examples include decks, garages, wall changes, basement or main-floor walkouts, plumbing, pools and structural changes to windows or doors.
Windsor lists decks, porches, sunrooms, garages, additions, structural door/window alterations, most wall additions/removals, plumbing/drain work and swimming pools among common permit projects.
The City notes that some minor repairs do not need a building permit and lists ordinary non-masonry fences among no-permit examples.
The homeowner can apply, or can authorize a contractor/designer, but the owner is responsible for ensuring the permit is in place before work starts.
