- Base trade permitCharged as a fixed amount rather than a percentage of the job.$60 – $250
- Per-unit / tonnage adderMany schedules add a charge per piece of equipment or per ton of capacity.$15 – $60
California adds a state Building Standards Administration Special Revolving Fund (SB 1473) charge based on job valuation, plus a seismic-mapping fee in most jurisdictions.
Method: valuation-based lines follow the stepped ICC/UBC Table 1-A progression that most residential schedules are still derived from, widened to reflect how much neighboring jurisdictions differ. Confirm the exact figure with the office listed on this page before you put it in a bid.
Inspection sequence
- Rough mechanical (when ducts are opened)
- Final mechanical
Never cover work ahead of the inspection that covers it — a re-open is the most expensive avoidable cost on a hvac job.
