Heavy RestrictionsADU Permits
Frisco restricts accessory dwelling units in single-family residential districts. The Frisco Zoning Ordinance permits only an accessory 'servant's quarters' or guest house incidental to the principal dwelling, and it cannot be operated as a separate rental household. A true detached ADU as a separate unit typically requires a Specific Use Permit (SUP) reviewed by Planning & Zoning Commission and City Council under Texas Local Government Code Ch. 211 zoning authority.

Heavy RestrictionsADU Impact Fees
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 §65852.2(f). Costs depend on whether the accessory unit requires a new water/sewer connection.

Some RestrictionsADU Owner Occupancy
Frisco's single-family residential zoning effectively requires owner-occupancy of any accessory unit by limiting each lot to one dwelling unit. An accessory guest house or servant's quarters cannot be rented as a separate household. Where a Specific Use Permit allows a true second unit, owner-occupancy is typically a recorded SUP condition. Texas has not preempted local owner-occupancy conditions.

Heavy RestrictionsADU Rental Restrictions
Frisco's single-family zoning prohibits renting an accessory guest house as a separate household. Where an SUP permits a true ADU, long-term (30+ days) rental is allowed if owner-occupancy continues. Short-term rentals (under 30 days) are subject to Hotel Occupancy Tax collection under TX Tax Code Ch. 156/351 and any local STR rules. Texas SB 987 (2023) was vetoed; STR preemption remains unresolved.
