Permit fees
Olympia mechanical permit fees for HVAC work
Olympia publishes a mechanical fee PDF on its Online Permit Portal. I pull those figures before I compare HVAC bids inside the city.

What I ask
- Who pulls the Olympia mechanical permit?
- Is the issuance fee and the unit line both in the price?
- If this is a new house under 2,500 sq ft, are you using the flat fee?
