Fulshear FAQ
Can I convert my garage to a bedroom in Fulshear?
Only with a permit. You must show egress, insulation, electrical, and mechanical compliance, and replace the off-street parking the garage previously provided.
What if I already converted my garage without a permit?
Contact Building Services to apply for an after-the-fact permit. Inspections will be required and the work may need to be opened up so inspectors can verify compliance.
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?
Many master-planned Katy communities prohibit garage conversions or require architectural review approval. Confirm with your HOA's deed restrictions before applying for a city permit.
