Addition diligence
Check possible unpermitted additions.
This page does not accuse a property of unpermitted work; it routes addition questions to official records and visible verification steps.
Quick answer
Screen possible unpermitted additions with official permit, inspection, certificate, parcel, and city record source paths.
Due-diligence answer first
This page starts with the address, then finds the permit authority.
Users searching permits by address want the record holder, record types, and official portal before they want a city directory. The page makes that path explicit.

Permit lookup questions
Unpermitted addition check: what should I search first?
Search the exact property address first. If the official portal does not match it cleanly, try parcel number, permit number, owner, contractor, or inspection record fields when the city exposes them.
Does Build Permit Radar show unofficial permit claims?
No. The site either displays official public records returned by a connected source or labels the result as an official-source route that still needs portal verification.
What permit records matter before buying or renovating?
Screen for open permits, expired permits, failed inspections, complaints, violations, trade permits, certificate records, and recent remodel or addition activity.
