Houston ADU Permit Fees & Cost Calculator
Houston appears to allow ADUs, but the exact permit and pre-development fee schedule is not clearly stated in the official materials surfaced here. The most reliable takeaway is that Houston’s permitting framework uses separate building/trade permits, and outside sources indicate no impact fees or school fees for ADUs, but those fee claims should be verified directly with Houston Permitting Center and Public Works.

FAQs
Are Houston ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Houston?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Texas?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
