Of all the public records a commercial HVAC contractor can watch, building and mechanical permits are the most direct. A permit means the work is real, funded, and moving, not a maybe. But a raw permit feed is noisy, and most of it isn't for you. The value is in reading it correctly.
Start with the permit type
Mechanical and HVAC permits are the obvious targets. They're filed specifically for heating and cooling work. But don't stop there. Commercial alteration, tenant-improvement, and new-commercial-construction permits frequently carry significant mechanical scope even when 'HVAC' isn't in the title. A large commercial buildout almost always needs new or upgraded systems.
Use valuation as a filter
The declared job valuation is a quick way to separate real commercial work from noise. A small residential furnace permit and a six-figure commercial alteration look similar in a database row, but only one is worth your time. Valuation, combined with the building's use and square footage, tells you whether there's enough scope to involve meaningful HVAC work.
Read the description and the building
The permit description and the property it's attached to fill in the picture: a rooftop-unit replacement, a new air-handling system, a restaurant buildout that needs make-up air, a warehouse conversion. A permit on a 40,000-square-foot commercial building reads very differently from one on a single-family home. Always open the source record and confirm before you act on it.
Timing is the whole point
Permits go stale quickly. A mechanical permit you catch the day it posts is an opening; the same permit two weeks later is often a job already spoken for. The contractors who win commercial work consistently are the ones watching the feed daily and reaching out while the project is still taking shape.
