Understanding Mechanical Permit Records

Mechanical permits often reflect HVAC replacements, building-system maintenance, remodels, and equipment upgrades. Repeated records at one property may indicate phased work, but a permit alone does not establish the condition of a system or whether the work is complete. Use the address, date, contractor, and description as starting points for further research.
