Permit Expiration and Unpermitted Scope Creep
An inspector visits a 1,900-square-foot single-family house after a complaint. The owner has a permit issued March 3 for a 14-foot by 22-foot master-bedroom addition. It is now December 18. The contractor says work began in November because the owner was waiting on a loan. In the field, the inspector sees the bedroom addition framed and dried in, plus two other projects: the existing screened porch has been converted to a conditioned office with new windows and a ductless heat pump, and a 10-foot by 12-foot deck is being built without a permit. The approved plans show only the bedroom addition; they do not show the porch conversion or the deck. The owner asks whether the inspector can "just look at everything today" and sign off. The contractor has not requested any revisions and says the porch and deck are "minor."
1. Is the March 3 permit still valid on December 18, and what should the inspector do before inspecting the bedroom addition?
Read the worked answer
No, not on its face. IRC R105.5 makes a permit invalid unless the authorized work begins within 180 days of issuance, or the work is not suspended or abandoned for 180 days after commencement. March 3 plus 180 days is about August 30; the contractor says work began in November, so the permit expired before work started. The inspector should not treat the expired permit as authorization for a routine inspection. The owner or contractor must ask the building official about renewal or a new permit, and the official may require re-review or justification for the delay. Any inspection before that is a courtesy look, not approval. If the jurisdiction has a local amendment extending or tolling expiration, apply it; otherwise document the file as expired.
2. What should be done about the porch conversion and the deck that are not on the approved plans?
Read the worked answer
They are separate work items requiring permits and review. R105.1 requires a permit for structural, electrical, mechanical, and plumbing work and for changes of use; converting a screened porch to conditioned office space changes the building envelope and creates habitable space. The deck is a structural addition with footing, ledger, guard, and stair implications. The inspector should not approve them as "minor" field changes. The contractor must submit construction documents for both, obtain permits, and schedule inspections. The inspector can issue a correction notice and, where the code official finds unsafe or unpermitted work, a stop-work order for those portions. The bedroom addition can be inspected only under valid authorization, if any.
3. What specific code issues should plan review look for in the porch-to-office conversion?
Read the worked answer
Because it becomes conditioned habitable space, review structural capacity of the existing porch framing and foundation; the energy envelope, including insulation, fenestration U-factor, air sealing, and equipment efficiency; egress and emergency escape provisions; light and ventilation; heating and cooling; electrical outlets and smoke/CO alarm coverage; and exterior wall flashing and waterproofing. The ductless heat pump must be listed and installed per manufacturer instructions, and the new windows must meet the climate-zone U-factor. If the existing porch was not designed for full enclosure loads, an engineered design may be required. The conversion also may trigger requirements for the new office's egress window and for separation from the garage or other hazards.
