Uncover essential details about San Jose’s Accessory Dwelling Unit (ADU) requirements. Discover zoning, permitting processes, design specifications, building codes, parking regulations, fire safety norms, utility connections, and financial incentives to guide your ADU project.
As the cost of living continues to rise in San Jose, many homeowners seek ways to maximize their property and generate additional income. One popular solution is building an Accessory Dwelling Unit (ADU), a granny flat or in-law unit. ADUs are secondary housing units built on the same lot as a primary residence and can be rented out for additional income or used for family members.
Before embarking on an ADU construction project, it’s essential to understand the city of San Jose’s regulations and requirements. This article will cover everything you need to know about building an ADU in San Jose.
San Jose has been proactive in promoting ADUs as a way to increase affordable housing options and address the growing population. As such, they have made it relatively easy for homeowners to build ADUs on their property. However, there are still regulations in place that must be followed.
Before embarking on your construction project, it is crucial to familiarize yourself with the San Jose ADU requirements. These regulations encompass zoning and land use requirements, the permitting process with associated fees, and size and design specifications for your ADU. By ensuring compliance with these guidelines, you can avoid potential legal hurdles and confidently move forward with your ADU construction.
The first step in building an ADU is to ensure that your property is zoned for one. In San Jose, ADUs are allowed in residential zones, including single- and multi-family zones. However, your specific zone may have additional conditions or restrictions.
It’s also important to note that your lot must meet specific land use requirements for building an ADU. These include minimum lot size, lot coverage, and open space requirements. The city’s planning and zoning website has more information about these requirements.

Before construction begins, you must obtain a building permit from the city. The process for getting a permit will depend on whether your ADU is attached or detached. You may also need additional permits, such as electrical or plumbing permits.
Each permit has a fee, which will vary depending on the size and type of ADU. As of 2021, the average cost for a permit is around $10,000. Investigating these costs is essential when budgeting for your ADU project.
The city of San Jose has developed the “ADU Universal Checklist” to help homeowners navigate the permitting process. This comprehensive guide outlines the steps and documentation required when applying for an ADU permit. Reviewing and following this checklist meticulously is vital to avoid any delays or complications in your project.
The city of San Jose has specific requirements for the size and design of ADUs. Attached ADUs can be no more than 50% of the primary residence’s size, while detached ADUs can be no more than 1,200 square feet. There are also height restrictions and design guidelines that must be followed.
It’s essential to consult with a professional architect or contractor to ensure your ADU plans meet all the necessary specifications before applying for a permit.
Additionally, the city encourages designs that harmonize with the existing primary residence and neighborhood character, reinforcing the importance of aesthetic considerations when planning your ADU. Understanding and adhering to San Jose ADU requirements ensures a smoother approval process and contributes to creating a housing solution that adds value to your property and enhances the community’s overall living experience.
In addition to the city’s ADU regulations, building codes and restrictions must be followed when constructing an ADU in San Jose.
These codes and restrictions encompass requirements related to parking, setbacks, fire safety, building inspections, and utilities and connections. Adherence to these regulations ensures that your ADU is legal, safe, and functional. These measures are implemented to maintain the integrity of residential areas and preserve the quality of life for all residents.
Parking is one of the most common concerns for homeowners looking to build an ADU. The city requires at least one parking space per unit, which can be waived under certain conditions. For example, if your property is located within a half-mile of public transportation, you may be exempt from providing parking.
Setback regulations must be followed, which dictate how close an ADU can be built to the primary residence and surrounding properties.
To ensure the safety of tenants, ADUs in San Jose must comply with fire safety regulations and undergo building inspections. Depending on the size and type of ADU, this may include the installation of smoke alarms and fire sprinkler systems.
Building inspections will be necessary at various construction stages to comply with San Jose ADU requirements. It is crucial to inform your contractor about these requirements to effectively incorporate them into the building plans.
When building an ADU, you must provide separate utility connections for the unit. This includes electricity, water, and sewer connections. In some cases, a second meter may be required for the ADU.
It’s essential to consult with your local utility department to determine what is needed for your specific property and ensure that all necessary connections are made during construction.
Building an ADU can be a significant investment, but financing options and incentives are available to help ease the financial burden.
The city of San Jose offers a loan program for low-income or moderate-income homeowners looking to build an ADU. State programs, such as the Accessory Dwelling Unit Financing Program (ADUFP), offer loans and grants to assist with ADU construction.
