Think about Building an ADU?

7 Helpful Steps to Get you Going

Several buyers asked my team and I, "What would it take to build an ADU (Accessory Dwelling Unit)?" so we came up with an initial list to help you with your California property to gain insights into the construction process and expenses to California ADU.
  1. Knowledge is Power: Take a look at Recent Changes to ADU Laws at CA.gov ADU Handbook and CA.gov HCD, California Department of Housing Accessory Dwelling Units (ADUs) site. These links are an excellent place to start your ADU research!
  2. Budget and Finance: Determine your budget for the project and explore financing options if needed. ADU and construction costs can vary based on factors such as size, design, materials, and customization.
  3. Building Permits and Zoning Regulations: ADU and construction often require obtaining the necessary permits and complying with local zoning regulations and California Government Codes. Researching and understanding your area's specific requirements is crucial to ensure a smooth construction process.
  4. Design and Customization: Consider your specific needs and preferences when it comes to the design and layout of your ADU. Many companies offer customization options, so discuss your ideas with the chosen company to ensure your vision aligns with their capabilities.
  5. Sustainability and Energy Efficiency: If sustainability is a priority for you, discuss green building practices, energy-efficient features, and material choices with the companies you're considering. Many companies offer eco-friendly options to minimize environmental impact.
  6. Timeline and Construction Process: Discuss the estimated timeline for the project with the company you choose. Understand the construction process, including any on-site work required and the duration of different phases, to have a realistic expectation of the project timeline.
  7. Warranty and After-Sales Support: Inquire about warranties provided by the company for their construction work, materials, and components. Additionally, understand the level of after-sales support they offer, such as maintenance, repairs, or any potential future expansion needs.
It is always a good idea to reach out to companies directly to confirm their current services, coverage areas, and any specific requirements or preferences you may have for your ADU project and see if they can help. It is also important to obtain accurate and up-to-date information regarding pricing and delivery commitment, ask for references, and visit ADUs they have built or showrooms.
