1. Verify eligibility:
Property owners must ensure that their property is eligible for an ADU. The property must be zoned for residential use and meet minimum lot size requirements.
2. Determine ADU type:
There are three types of ADUs allowed in San Jose: Attached, Detached, and Junior. Property owners must determine which type of ADU they want to build and ensure that it meets the requirements of that specific type.
3. Check setbacks:
The ADU must meet setback requirements, which specify how far the structure must be from the property line and other structures. Setbacks can vary depending on the type of ADU and the zoning of the property.
4. Check height limits:
The height of the ADU must comply with local zoning laws. In San Jose, the maximum height for a detached ADU is 16 feet and the maximum height for an attached ADU is 28 feet.
5. Check parking requirements:
Depending on the location and type of ADU, there may be parking requirements that must be met. Generally, one parking space is required for each ADU unit.
6. Obtain necessary permits:
Property owners must obtain the necessary permits for construction, electrical, and plumbing work. They must also have their plans reviewed by the Department of Planning, Building, and Code Enforcement.
7. Follow building codes:
The ADU must comply with local building codes and safety regulations. This includes requirements for fire safety, insulation, and electrical systems.
8. Schedule inspections:
Inspections are required throughout the construction process to ensure that the ADU is being built safely and in compliance with local laws and regulations.
9. Obtain certificate of occupancy:
Once construction is complete, property owners must obtain a certificate of occupancy before the ADU can be occupied.
10. Consult with a professional:
Building an ADU can be a complex process. Property owners may want to consult with a professional, such as an architect or contractor, to ensure that their ADU is built properly and in compliance with local laws and regulations.
