Collin County unincorporated areas have no zoning and therefore no home occupation permit requirement. Texas Local Government Code 231 limits county regulatory power. Residents must still comply with city rules if inside Plano, McKinney, Frisco, Allen, or Wylie limits.
Under Texas Local Government Code Chapter 231, Collin County has no general zoning authority over unincorporated property. Home-based businesses operate without a county permit provided they do not violate state nuisance law, septic rules (TCEQ 30 TAC 285), or on-site sewage facility permits issued by Collin County Development Services. Commercial signage on county roads requires TxDOT permit if within ROW. All cities in Collin County regulate home occupations via zoning: typically one non-resident employee, no retail customers, no outdoor storage.
No county citation mechanism. Nuisance complaints handled through civil courts or state agencies (TCEQ for septic, comptroller for sales tax).
