Accessory Dwelling Units (ADUs) are becoming a popular choice for San Jose homeowners looking to add space, increase property value, or generate rental income. If you’re considering building an ADU, here’s a step-by-step guide to help you navigate the process in San Jose.

1. Understand Local ADU Regulations

San Jose has specific zoning, size, and setback requirements for ADUs. Check with the city’s planning department or consult an experienced design-build contractor to ensure your project complies with local laws and HOA rules.

2. Assess Your Property

Evaluate your lot’s size, shape, and existing structures to determine the best location for your ADU. Consider access, privacy, and how the new unit will complement your main home.

3. Set Your Budget

Establish a realistic budget that includes design, permits, construction, and potential utility upgrades. Don’t forget to plan for unexpected costs and set aside a contingency fund.

4. Design Your ADU

Work with a professional to create a design that maximizes space and meets your needs. Think about floor plan efficiency, natural light, storage solutions, and how the ADU will be used—whether for family, guests, or rental income.

5. Obtain Permits and Approvals

Submit your plans to the City of San Jose for review. Permitting can take time, so be prepared for possible revisions and inspections. Your contractor can help streamline this process and ensure compliance with all regulations.

6. Hire the Right Contractor

Choose a licensed, local contractor with ADU experience in San Jose. Check references, review portfolios, and make sure communication is clear and expectations are set from the start.

7. Construction Phase

Once permits are secured, construction begins. Your contractor will handle site preparation, foundation, framing, utilities, and finishing work. Regular check-ins help keep the project on schedule and address any concerns quickly.

8. Final Inspections and Move-In

After construction, the city will conduct final inspections to ensure your ADU meets all codes and safety standards. Once approved, you’re ready to move in or start renting out your new space!
