Generators in Katy: FAQ
Which generator installers serve Katy?
The 13 companies on this page name Katy on their own website or in their BBB service area. A company not listed here may still serve Katy, so call to confirm your address.
Do I need a permit for a standby generator in Katy?
Katy spans Harris, Fort Bend, and Waller counties. In unincorporated Fort Bend County, the County Fire Marshal is the permitting authority and reviews electrical plans. Inside Katy city limits, or in unincorporated Harris or Waller County, check with your city or county, or have your installer pull the permit. Sources: Fort Bend County Fire Marshal: construction permits.
Can my HOA stop me from installing a standby generator?
No. Texas Property Code 202.019 says an HOA can't ban or effectively prevent a permanently installed standby generator rated 7 kW or more. It can set reasonable rules on placement, screening, testing times, and licensed installation. Sources: Texas Property Code 202.019 (Justia).
