Why this page exists
Most contractor-finder sites check state license status but don't verify that the contractor actually pulls permits when required. A licensed contractor who skips permits leaves the homeowner holding the bag, code violations, insurance complications, and problems at resale.
This page shows John O'mahony's public permit-pulling record in Massachusetts. It's sourced from official city open-data feeds, not self-reported. If you're interviewing contractors, ask the ones you're considering to explain any gaps or closed permits you see here.

How to vet this contractor further
- Check their state license with your state's licensing board. This page shows permit behavior, not license status.
- Ask for 3 recent references from the cities above. Match them against the permit addresses here.
- Look for gaps. Are there years with many permits, then nothing? Contractors sometimes let licenses lapse or change business names.
- Verify active bonding and workers' comp insurance. Ask for certificates directly from the insurer, not a copy from the contractor.
