Building an Accessory Dwelling Unit (ADU) can be a fantastic way to add value to your property, create additional living space, or generate rental income. The process can vary depending on your location and specific project requirements, but generally, it follows a series of well-defined steps. Here’s a comprehensive guide to help you navigate the process of building an ADU, with tips on how EG Modern Construction can support you throughout.


Step 1: Research and Planning


Local Regulations:

  • Zoning and Codes: Research local zoning laws and building codes to understand what is permitted on your property.

  • Consultation: Talk to your local planning department to confirm prerequisites and restrictions.


Project Planning:

  • Size and Design: Consider the size, location, and design of your ADU.

  • Needs Assessment: Develop a plan that meets your needs and complies with local regulations.


Step 2: Financing


Budgeting:

  • Cost Estimation: Estimate the total cost of building your ADU, including design, permits, construction, and finishing.


Financing Options:


  • Home Equity Loan: Leverage your home’s equity.

  • Mortgage: Consider a new or refinanced mortgage.

  • Cash Payment: Use savings if available.

  • Consult Financial Advisor: Explore the best financing option for your situation.


Step 3: Design and Permits


Professional Assistance:

  • Hire a Designer/Architect: Engage a professional to design your ADU and prepare necessary plans and documents.


Permit Applications:

  • Building Permits: Apply for building, plumbing, electrical, and other necessary permits.

  • Regulatory Compliance: Ensure all designs meet local regulations and codes.


Step 4: Construction


Hiring a Contractor:

  • Select a Contractor: Choose a reputable contractor to handle the construction.


Building the ADU:

  • Site Preparation: Excavate and prepare the site.

  • Foundation: Pour the foundation according to the approved plans.

  • Framing and Structure: Frame the structure, install the roof, and put up walls.

  • Utilities Installation: Set up plumbing, electrical systems, and HVAC.

  • Interior and Exterior Finishing: Complete the interior (drywall, flooring, fixtures) and exterior (siding, windows, doors).


Step 5: Inspections


Regulatory Inspections:

  • Scheduled Inspections: Have your ADU inspected at various stages of construction (foundation, framing, utilities, final).

  • Code Compliance: Ensure your ADU meets all applicable building codes and safety standards.


Step 6: Occupancy


Final Steps:

  • Certificate of Occupancy: Obtain this certificate from the local building department to confirm the ADU is safe and fit for habitation.

  • Move-In or Rent Out: Once complete, you can move in or rent out the ADU.


Consider Legal and Management Aspects:
