Replacing a water heater in Sienna.
Whether you need a permit to replace a water heater in Sienna depends on your address. Parts covered by Missouri City's annexation agreements follow Missouri City's rules: a $35 application fee plus $35 for the water heater. Unincorporated sections have no county water heater permit. CenterPoint delivers power, and water comes from Sienna's MUDs, run by Si Environmental.
Sienna is an unincorporated community in Fort Bend County, so county offices handle permits.
