search_permitsSearch U.S. building permits by location (city, state, ZIP code, or a lat/lng radius), category, status, property type, filing or issue date range, estimated project value, contractor name, or free text. Returns up to 25 permits per call with address, dates, category, status, es…
get_permitLook up a permit by the permit number assigned by the issuing jurisdiction, optionally narrowed by city and state. The number is matched exactly (ignoring case), and the same number can exist in several jurisdictions, so up to 5 matching permits are returned; give the city or st…
get_property_historyPermit history for one property, looked up by street address (house number and street name, e.g. '123 Main St'). Optional city, state and ZIP narrow the match when the same street address exists in several places. Returns a property profile (permit timeline, category breakdown,…
search_contractorsSearch contractors by name, city, state or specialty. Returns up to 25 contractors per call with the contractor UUID, name, licence number and licence state, home city and state, total permit count, first and last permit dates, specialties and activity score (0-100), sorted by a…
get_contractor_permitsList the permits pulled by one contractor, identified by the contractor UUID from search_contractors. Returns up to 25 permits per page with the contractor's work history fields (dates, categories, values). Results carry no property owner name, owner mailing address or permit ap…
get_coverageDescribe PermitStack's coverage: total permits, jurisdictions (active, archive, frozen) and states. On a signed-in connection it also lists covered jurisdictions with their permit counts, county and `data_through` (the date of the newest permit held), filterable by state and by…
search_inspectionsSearch inspection logs by place, permit, type, result and date. Summaries and future scheduled inspections are excluded by default; upcoming and summaries opt in. Sources report data_through. Coverage varies by source and place; an empty result does not establish that no record…
get_permit_inspectionsList inspections linked to a permit UUID. Future scheduled inspections are excluded by default unless result=SCHEDULED or upcoming opts in. An empty list means no linked inspection is held. Coverage varies by source and place; an empty result does not establish that no record ex…
search_violationsSearch agency findings by place, case number, status, category and date. record_kind defaults to violation; complaints are reports, not confirmed violations. Sources report data_through, coverage_window and count_unit. Coverage varies by source and place; an empty result does no…
get_violationGet a violation or complaint by UUID, including source status and related copies. A complaint is not a confirmed violation. Coverage and published fines vary by source.
search_pipeline_casesSearch planning and zoning cases by place, type, status, dates and proposed size. A planning case does not guarantee construction. Sources report data_through. Coverage varies by source and place; an empty result does not establish that no record exists. Up to 25 results per cal…
get_pipeline_caseGet a planning case by UUID with linked decisions and permits. A permit link matches site and time, not proof it was issued under this case; link_method and confidence describe the match. A planning case does not guarantee construction. Coverage varies.
search_pipeline_decisionsSearch council, planning commission and zoning board decisions by place, body, action and meeting date. RECOMMENDED_* is a recommendation, not a final decision. A decision does not guarantee construction. Coverage varies by source and place; an empty result does not establish th…
search_certificatesSearch certificates of occupancy or completion. Defaults exclude renewals; co_date_basis states what each date means. Completion certificates do not establish occupancy, and pending applications are not issued certificates. Coverage varies by source and place; an empty result do…
get_certificateGet an occupancy or completion certificate by UUID, including certificate_status and co_date_basis. A duplicate id resolves to its canonical record. Coverage varies; a completion certificate does not establish occupancy.
lookup_licenseLook up a license number in its issuing state across the public board rosters held, with matching contractors. Coverage and as_of dates vary by board. Access and locked_fields identify unavailable fields; a registration is not a license. No contact enrichment.
get_contractor_licensesList public board licenses linked to a contractor UUID by the API's exact matching rules. Coverage and as_of dates vary by board. Access and locked_fields identify unavailable fields; a registration is not a license. No contact enrichment.
get_dataset_coverageList source and place coverage for inspections, violations, pipeline cases/decisions or certificates. Includes the API's measured freshness, completeness and caveats where available. Counts have source-specific meanings; complaints are separate from violations. Requires sign-in.…
