Each record can show the project address, scope, permit type, and value where the city publishes them. The source-published contractor records do not meet the coverage threshold for this city. PermitGrab does not represent this as contractor-contact coverage. Where property-owner records are available, they are matched to permit addresses separately.
Filter the current records by trade, date, address, or project value to research construction activity. The most useful workflow in this market is verifying the project signal first, then using the property data that is actually available for that address.
