Who Will Be Involved in Your ADU Project?

1. General Contractors

General contractors oversee the entire ADU construction process, coordinating various trades and subcontractors, ensuring the entire project is overseen and completed under their direction. Their services include:

  • Project Management: Supervising all aspects of construction from start to finish. All work is done under their license and covered by their insurance.
  • Subcontractor Coordination: Hiring and managing specialized trades such as electricians, plumbers, and carpenters. Often times these subcontractors have worked with the General Contractor on previous projects, and they have a professional relationship. This helps improve communication and project speed.
  • Permitting and Inspections: Handling the acquisition of necessary permits and scheduling inspections to comply with local regulations.

2. Architecture and Engineering

While not contractors, these professionals play a crucial role in the planning phase. They help you imagine and design the type of unit that can fit in your space. And also help you turn your dream, to a reality with a blueprint. Their services involve:

  • Site Analysis: Evaluating your property to optimize the ADU's placement and design.
  • Custom Design Services: Creating unique ADU plans that align with your aesthetic preferences and functional needs.
  • Permit Documentation: Preparing detailed plans and documents required for permit approval.
  • Engineering Services: Ensuring structural integrity and compliance with building codes & zoning laws, which vary significantly between local counties.

3. City / County Department of Building & Safety

Department of Building & Safety can be City or County operated, depending on your location. They are the most significant part of success in your ADU project.
