Code Compliance for ADUs


Ensuring your ADU meets all regulatory standards is critical. We focus on meeting detailed building codes, fire safety rules, and utility standards to help you avoid costly issues and delays.

Building Code Requirements


We ensure your ADU complies with local and state building codes, including structural integrity, egress, ceiling height, and ventilation.


Key requirements include:


  • Minimum ceiling heights, usually 7 feet or higher

Fire safety is a priority in ADU construction. We ensure compliance with fire-resistant materials, smoke detection systems, and safe exit routes.


Important points:


  • Installation of smoke and carbon monoxide detectors per code
  • Use of fire-rated siding and roofing materials
  • Fire separation between the ADU and main house or property lines
  • Clear, unobstructed emergency exits


Our team works closely with local fire departments to meet or exceed these requirements, protecting occupants and property.
