Fort Worth FAQ
What does a Fort Worth ADU cost in fees?
Total city fees typically run $4,500-$9,500 for a new ADU: roughly $2,500-$3,500 water impact fee, $1,800-$2,800 wastewater impact fee, $500-$2,500 roadway impact fee (varies by zone), and $500-$1,500 building permit and plan check. Texas has no sub-750 sq ft fee exemption.
Are smaller ADUs cheaper to permit in Fort Worth?
Slightly. Plan check fees scale with project value, but impact fees are charged per dwelling unit regardless of size. Unlike California, Texas has no law waiving impact fees for ADUs under 750 sq ft - Fort Worth applies the full schedule.
Can I share my Fort Worth ADU's water meter with the main house?
Sometimes. Sharing meters may reduce water impact fees if the Water Department determines no new capacity is needed. Submit the request with your building permit application; new sewer impact fees usually still apply because the ADU adds wastewater demand.
