Hayward
Here is the Hayward rule in plain words, and what we do when a wall heater or HVAC unit is swapped.
City permit rule
Hayward requires a building permit to remove and replace an HVAC unit, or to install a new unit for the first time.

Air Champs
When a Hayward wall heater stops lighting, we look at the vent, the gas shutoff and the clearances before anything else. Then we tell you whether it can be fixed or should be replaced, or whether a ductless system makes more sense for the house.
Bay Area Air District
Hayward sits inside the Bay Area Air District, covering Alameda County.
