During Harvey in 2017, controlled releases and pooling behind the Addicks and Barker reservoirs flooded homes in west Houston and the Katy area for days. Most Katy subdivisions rely on municipal utility district detention ponds and street drainage. During long, intense rain, overloaded drainage can push water into garages and low-lying homes even when the bayous aren't overflowing. Knowing your MUD and floodplain status helps with insurance decisions.
Many Katy homes have attic air handlers and water heaters, and two-story designs with upstairs laundry rooms. The address may fall in the City of Katy, unincorporated Harris or Fort Bend County, or a municipal utility district (MUD), which affects who issues permits.
Licensing in Texas: Texas doesn't license general contractors statewide, but it licenses mold assessors and mold remediation contractors through the Texas Department of Licensing and Regulation (TDLR) for projects of 25 contiguous square feet or more.

Sewage & Biohazard Cleanup questions
Who issues building permits in Katy?
It depends on the address. The City of Katy handles homes inside city limits; unincorporated areas go through Harris County or Fort Bend County Engineering.
Is my Katy home in a flood risk area?
Check FEMA's flood map and the Harris County Flood Control District's tools. Many Katy homes that flooded in 2017 were outside the mapped 100-year floodplain.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
