Do I need a permit for window or exterior door replacement in Blue Ash?
It depends. Whether window or exterior door replacement needs a permit in Blue Ash comes down to the details of your project.
Under the Residential Code of Ohio a simple like-for-like window or door swap in an existing opening is often treated as ordinary repair, but enlarging an opening, altering a header, or changing an egress window is structural work and requires a permit in most Ohio jurisdictions. Bedroom (sleeping room) windows must still meet RCO emergency escape and rescue opening requirements even when a permit is not pulled. Blue Ash allows replacement windows and new storm windows or doors in existing openings without a building or zoning permit when there are no structural changes or repairs. New wall openings for windows or doors, or any opening that is enlarged, do require a building permit in Blue Ash. If you are unsure whether your opening change is structural, call the Blue Ash Building Department at 513-745-8522.
