Killeen ADU Permit Fees & Cost Calculator
Killeen’s official fee schedule is the best source for ADU-related permit costs, but the publicly available excerpts do not clearly isolate a separate ADU fee. The city’s FY 2025 proposed fee schedule and FY 2024 adopted fee schedule indicate permit fees vary by category and can range from low minimums to higher project-based amounts, so the exact ADU total still needs verification with Building Inspections.[1][5]

Fee overview
Do not treat the $20 to $2,500 range as an ADU fee; it is a broad city permit-fee reference only.
ADU-related utility connection, inspection, and school fees were not confirmed from official sources in the provided results and should be verified directly with the city, utility provider, and local school district.
Killeen may require an ADU to be permitted under an existing residential building permit category rather than a standalone ADU fee.
The public search snippets provided do not expose the full fee table, so numeric ADU-specific permit costs are not asserted here.
Killeen fee estimates should be verified against the current city, utility, and school district fee schedules before filing.
This page has limited structured fee data and should be treated as a low-confidence planning estimate.
