Free Home Safety & Water Quality Tools
Every tool is free, requires no signup, and runs on real federal data — EPA water testing results, FEMA flood zones, EIA energy rates, and Census housing records. Enter your ZIP code to get started.
Why These Tools Exist
Most homeowners have no idea what contaminants are in their tap water, whether radon is seeping into their basement, or if their home sits in a flood zone. That information exists in federal databases — EPA, FEMA, CDC, USGS, HUD, EIA — but it is buried in technical reports that are difficult to find and harder to read.
ZipCheckup pulls data from 50+ federal and state sources and translates it into plain-language results for any U.S. ZIP code. Every tool is free, requires no signup, and returns instant results. Enter a ZIP code, get answers.
Data from: EPA SDWIS • FEMA NFIP • CDC ATSDR • USGS • EIA • HUD • Census ACS • NOAA • PHMSA
