Katy FAQ
Do I need a permit to convert my garage to living space in Katy?
Yes. The change of use triggers a residential building permit under the 2021 IRC adopted by Katy effective January 1, 2024, plus trade permits for any electrical, plumbing, or HVAC work.
Can I rent the converted garage as a separate apartment?
No. Katy's Zoning Ordinance Exhibit 14A limits accessory dwelling units to family, guests, or employees working within the residence and prohibits commercial use, including renting to unrelated tenants.
Will my Katy HOA allow a garage conversion?

Yes, with a building permit. The conversion must meet all habitable space requirements under the 2021 IRC and cannot eliminate required off-street parking (typically 2 spaces per dwelling unit). HOA approval is also typically required.
Do I need to replace parking if I convert my garage?
