Definition
Unpermitted work is any construction, addition, or system change completed without the building permits and inspections the local government requires. Common examples include garage conversions, finished basements, added bedrooms or bathrooms, decks, and electrical or plumbing changes. It can create problems when you sell: appraisers may not count the space as living area, lenders may hesitate, insurers may deny claims tied to the work, and a buyer's inspection or a permit search can reveal it. In some cases the city may require you to permit it retroactively, bring it up to code, or remove it. Sellers typically have three options: obtain an after-the-fact permit, which can involve opening walls for inspection; remove or reverse the work; or disclose it and sell to a buyer willing to accept it. Most state disclosure rules require sellers to share known unpermitted work, so honesty protects you from claims after closing.
Real seller example
Ellen Foster's previous owner had converted the garage into a bedroom without permits. When she prepared to sell, a buyer's appraiser refused to count it as living space, and the lender questioned the value. She priced out a retroactive permit and learned the inspector would need sections of drywall removed to check wiring and insulation. Rather than open the walls and wait on re-inspection, she disclosed the conversion in writing and sold to a cash buyer who accepted the room as-is. Her disclosure kept the sale clean and protected her afterward.
