Permit history for unincorporated County of Napa
PermitProof runs an automated search here, but it does not currently hold a passing live acceptance certification. It publishes what it reads when the result is conclusive; an unfinished read is labeled incomplete alongside whatever it did read, and a search here is never answered with an uncertified “no permits found”.
A stored result of an identical search may be reused for up to 30 days, and a read that could not finish is labeled incomplete - never presented as a completed permit history, and never as "no permits found". Full reuse windows and how sources are chosen.
Portal software recorded in the catalog: Accela Citizen Access.
Where a search cannot establish something, the report says so in that row - it never fills a field in, and it never reports “no permits found” without certified evidence.
What the catalog records about this source
The catalog records the official source as the county's Accela Citizen Access portal and links directly to its Building Permit Search page, because the portal's landing pages only frame the search rather than rendering it themselves and appear empty to an automated search. The linked page, checked at the end of July 2026, presents a general search with street number, street name, city, and ZIP fields and no login. PermitProof's automated search runs against this source, but no passing live acceptance test is on record.
