Know the neighborhood
Address checks from public records, updated November 2026.
Short answer
Put in an address and see which public schools serve it, whether it's in a FEMA flood zone, where the lot lines run and what the state lets you build. Each answer comes from the agency that keeps the record, with its date, so you know how current it is.
The checks
School zone lookup
The school district for any US address, the elementary, middle and high schools its zone was assigned, and other public schools within 1.5 miles. From NCES.
Flood zones
FEMA’s flood map over the aerial photo, with the zone, the base flood elevation and whether flood insurance is mandatory. Turn on Flood zones on the measuring map.
Historic places
National Register of Historic Places districts and buildings at the spot, with the year listed and the nomination form, from the National Park Service. Turn on Historic places on the measuring map.
Property lines
County lot lines over the photo in the states and metros that publish them for reuse, with the distance from anything you place to the line.
Split the lot (California)
Draw an SB 9 lot split on your lot and check each half against the state’s size rules and FEMA’s flood map.
What you can build
ADU rules in California, Washington and Oregon: size, height, setbacks, parking and fees, from each state’s law.
How current it is
School districts and school details are for the 2024–25 school year. Attendance zones are from 2015–16, the last nationwide survey, so the lookup says which schools it found then and whether each still operates. Flood zones are FEMA's effective maps. Property lines are each county's current layer. None of it replaces the official record: the district for schools, FEMA's Flood Map Service Center for flood determinations, and a survey for lot lines.
