Safety & Official Resources

Know who is speaking. Government agencies, industry organizations and this directory have different roles.

CPSC: carbon monoxide fact sheet

CO warning signs, alarm guidance and what to do when exposure is suspected. Carbon monoxide cannot be detected by smell.

CSIA: homeowner resources

Chimney maintenance education, inspection background and routes to professional credential information.

CSIA: certification information

Understand what a chimney credential represents. Confirm the individual technician and current credential separately; certification is not insurance or a government license.

Find the authority for your actual address

For permits, adopted codes and local inspection requirements, contact your city or county building department. For burn restrictions and air-quality rules, check the applicable local air-quality authority. Do not infer a rule from a neighboring town or a national article.

For animal activity, ask the relevant wildlife authority about species identification and lawful handling before a nest is disturbed. A chimney contractor may need to coordinate with a wildlife professional.
