Public-record due-diligence facts for a US residential address. Any US address: FEMA flood zone at the geocoded point, HUD FY2026 Small Area FMR (or area FMR) by bedrooms, and a property-tax estimate: official rates in Nashville (Metro rate), Denver (levy by tax district), Chicago (Cook County tax code) and Maricopa County cities (tax area code), elsewhere a rough county-level estimate from Census ACS, labeled as such. Full parcel-level coverage (zoning district, overlays, STR permit eligibility for owner-occupied vs non-owner-occupied, caps, existing STR permits/licenses) only in Nashville/Davidson County TN, Denver CO, Scottsdale AZ, and Chicago IL (building size, Prohibited Buildings List, Restricted Residential Zones). New York City (city-wide rules plus a per-building Prohibited Buildings List and registration check by BIN) and Austin TX (city-wide rules plus a per-parcel full/limited-purpose/ETJ check) are also covered, as are Phoenix, Mesa, and Tempe AZ (city-wide rules); str.granularity says which. Elsewhere zoning/STR return not_covered. Every value carries a source and as-of date. HOA/deed restrictions are not checked. Informational only; not legal/tax/insurance/lending advice. Same tool as nashville_deal_check. Status values. Top-level status: ok = every evaluated section answered; needs_review = partial answer, at least one section needs a person or a retry (read each section's status and the warnings); unavailable = no section could be answered (address not found, or every source failed); out_of_scope = no evaluated section applies at this address. Section status uses the same words plus not_covered (this area is not evaluated). str.status follows the two permit determinations: new_non_owner_occupied_permit.value (allowed, not_allowed, needs_review, out_of_scope, not_covered, unavailable) and owner_occupied_permit.value (possible, not_allowed, needs_review, out_of_scope, not_covered, unavailable). Both firm = ok, one firm and one not = needs_review, none usable = unavailable. str.supporting_data_status appears when side lookups such as permit counts or building lists were incomplete.
