Garland, TX Accessory Structures: ADU Impact Fees (2026)

Garland does not offer ADU-specific impact fee waivers. Standard development charges apply: building permit fees based on construction valuation under the Garland fee schedule, plan-check fees, and trade permit fees (electrical, plumbing, mechanical). Garland collects water and wastewater impact fees under Texas Local Government Code Chapter 395 (Impact Fee Act) and the City's adopted Land Use Assumptions and Capital Improvements Plan. Roadway impact fees may apply in adopted roadway service areas. Where an accessory unit shares the principal dwelling's existing water and sewer tap, most impact fees are avoided - Garland Water Utilities and Public Works encourage this approach. Oncor handles electric service; Atmos Energy supplies natural gas in most of Garland (Garland Power & Light, the municipal utility, serves the electric grid for many parts of the city) - service-extension fees apply separately. Texas has no statewide ADU impact-fee waiver comparable to California Gov. Code Sec. 65852.2(f) or Arizona ARS Sec. 9-461.18. The Dallas Central Appraisal District will reassess the property after the certificate of occupancy issues, increasing property tax bills.
