Killeen ADU / Accessory Dwelling Rules
Some RestrictionsADU Permits
Killeen regulates accessory dwelling units through its Unified Development Code (UDC) and Chapter 31 (Zoning) of the Code of Ordinances. ADUs are not permitted by right in single-family (SF) districts and typically require a Specific Use Permit (SUP) reviewed by the Planning and Zoning Commission and approved by City Council. Building permits are issued through Killeen Building Inspections after the SUP is granted. Texas has not preempted local discretionary review of ADUs.

Killeen assesses standard water, wastewater, and roadway impact fees on new dwelling units, including ADUs requiring new utility connections, under Texas Local Government Code Chapter 395. Building, plan-check, and trade permit fees are collected by Killeen Building Inspections through the city's permit portal. Texas has no ADU-specific impact-fee waiver; sharing the principal dwelling's water/sewer tap is the most common way to reduce fees.

Some RestrictionsADU Owner Occupancy
Killeen City Council routinely imposes owner-occupancy as a condition of the Specific Use Permit granted for accessory dwelling units in single-family districts under Chapter 31 (Zoning). The owner must occupy either the principal dwelling or the ADU as a permanent residence, typically secured by a deed restriction recorded with the Bell County Clerk. Texas has not preempted local owner-occupancy rules, and Fort Cavazos PCS turnover makes the requirement particularly relevant in Killeen.
