Data Sources

The public sources behind Mold Compass guidance, state pages, city pages, tools, and Ask Scout.

Mold Compass uses different source types for different page categories. General guidance leans on public health and remediation standards, legal pages use state and local authorities, and risk tools use the climate and housing datasets listed below.

Public Health, Cleanup, and Standards Sources

Environmental Protection Agency mold guidance Moisture control, cleanup, and homeowner guidance.
CDC and NIOSH mold testing and remediation guidance Testing limits, visual inspection, remediation, and workplace health framing.
CDC and NIOSH damp-building health guidance Respiratory, allergic, and asthma-related health context.
OSHA mold resources Worker safety and remediation hazard guidance.
ANSI/IICRC S520 standard Professional mold remediation standard referenced for remediation planning.
WHO dampness and mould guidelines Health literature review for dampness, microbial growth, and respiratory risk.

State and Local Legal Sources

State guides are built from state statutes, landlord-tenant agencies, attorney general or consumer-protection resources, health departments, court or legal-aid resources, and state licensing boards where mold-related licensing or remediation rules exist.

City pages add official city or county resources when available, such as code enforcement, housing, building, rental registration, or public health pages. Those local resources supplement state law; they do not replace it.

Climate, Housing, and Risk Data

NOAA NCEI US Climate Normals City climate indicators and station links for temperature, precipitation, and related climate context.
US Census ACS 5-year data Housing-age data, including median year built where available.
US Census geocoder ZIP and coordinate lookup used by the risk tool.
US Census TIGERweb ZIP Code Tabulation Area geometry used by the risk tool.
Open-Meteo historical weather API Recent weather signals used by ZIP mode in the risk tool.

Ask Scout Sources

Ask Scout draws from Mold Compass pages that have been added to the site, including public guides, tools, state pages, and city pages. When it answers, it points readers back to relevant Mold Compass pages so they can review the underlying guidance and links.

Source Limits

External source pages can move or change. Mold Compass links sources where they support a claim, but readers should verify urgent legal, medical, insurance, or remediation decisions with the appropriate professional or agency.
