Frisco charges standard impact and utility fees on new dwelling units under Texas Local Government Code Chapter 395 authority, including water and wastewater impact fees and roadway impact fees in service areas. Texas has no statewide ADU impact-fee waiver comparable to California Gov. Code Β§65852.2(f). Costs depend on whether the accessory unit requires a new water/sewer connection.
Frisco does not offer ADU-specific impact fee waivers. Standard development fees apply: building permit fees based on construction valuation under the Frisco Building Inspections fee schedule, plan review fees, and trade permit fees (electrical, plumbing, mechanical). Frisco 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 β rates are periodically updated by ordinance after the Capital Improvements Advisory Committee process and a public hearing under Β§395.0575 and Β§395.058. Roadway impact fees also apply in adopted roadway service areas. Chapter 395 is strict procedurally: fees must be supported by an adopted Land Use Assumptions report, Capital Improvements Plan, and rate study, and must be reasonably attributable to the new development. Where the accessory unit shares the principal dwelling's existing water/sewer tap and meter, most impact fees can be avoided β Frisco Public Works generally encourages this approach to minimize cost. Oncor handles electric service in Frisco; Atmos Energy supplies natural gas; service-extension fees apply separately. Texas has no statewide ADU impact-fee waiver analogous to California Gov. Code Β§65852.2(f). Property taxes will adjust through the Collin Central Appraisal District (or Denton CAD for parcels in that county) annual reassessment.
Failure to pay impact fees: permit denial or revocation; the City may refuse to provide utility service connection until fees are paid under TX LGC Β§395.019. Building without paying connection fees: Frisco Public Works disconnection authority and possible Code Compliance citation. Lien rights for unpaid fees may attach under Texas Tax Code Ch. 33.
