Methodology
The "cost of ownership" figure is a modeled estimated additional annual cost of owning a home in a ZIP code, expressed as the difference vs a median-risk U.S. ZIP. It aggregates hazard-related costs across 13 verticals:
- Drinking water quality, lead, and PFAS
- Radon, flood, wildfire, and earthquake exposure
- Mold, carbon monoxide / gas, and air quality
- Housing age, infrastructure condition, and affordability pressure
Inputs are public datasets from the EPA, FEMA, USGS, and the U.S. Census Bureau. The figure is an area-level estimate — it does not reflect the condition, price, or actual expenses of any individual home, and it is not a quote, a bill, or financial advice. Datasets refresh on a quarterly schedule.

Frequently Asked Questions
What does "cost of ownership" mean here?
It is a modeled estimate of the additional annual cost of owning a home in a ZIP code compared with a median-risk U.S. ZIP. The estimate combines 13 environmental and housing hazard verticals — water quality, lead, radon, flood, wildfire, and more. Every figure is an estimate derived from public federal data, not a quote or a bill.
How is the additional annual cost calculated?
For each ZIP, hazard-related costs across 13 verticals are aggregated and compared with those of a median-risk U.S. ZIP. The difference is the modeled additional annual cost. Inputs come from EPA, FEMA, USGS, and U.S. Census data. Figures are area-level estimates and do not reflect the condition of any individual home.
Does a high ranking mean homes there are unsafe or overpriced?
No. The ranking reflects area-level environmental and housing data, not the condition or price of any individual property. It is a planning estimate to help homeowners and buyers budget — not a judgment about a neighborhood or a home.
Are these figures quotes I will be charged?
No. ZipCheckup is an information service. The figures are modeled estimates from public federal data and are not quotes, bills, financial advice, or a guarantee of any future cost.
