Do I need a permit for hvac replacement or installation in Dayton?

Permit required

Yes. In Texas, hvac replacement or installation generally requires a permit, and Dayton is no exception.

Replacing or relocating HVAC equipment requires a mechanical permit in most Texas cities, and many issue same-day express permits for like-for-like changeouts. Changing equipment location or adding electrical or gas connections can add trade permits and inspections. Confirm the scope with your local building department. Dayton's fee schedule charges $55 for residential air conditioning up to 5 tons and $55 for gas heaters, plus the $30 permit issuance fee. A mechanical reinspection is $70. The homestead affidavit on the city's mechanical application allows an owner to do the work only by themselves, on their own homestead, with no one employed to help.
