Frequently Asked Questions

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. Building an ADU in San Jose offers significant benefits, including generating rental income, providing housing for family members, or creating a dedicated home office or studio space. With housing demand high and land at a premium in San Jose, an ADU is a smart way to maximize your property's value and utility, often without needing to purchase more land. We help you understand the specific San Jose regulations that make ADU construction an attractive option for many homeowners.
In San Jose, typical ADU size limits allow for up to 1,200 square feet for detached units, or 50% of the existing primary dwelling's floor area, whichever is less, with some flexibility. Setback requirements are generally minimal, often allowing for 4-foot side and rear setbacks for detached ADUs, which is a significant relaxation from previous rules. We stay current with the latest San Jose Planning Department guidelines to ensure your ADU design complies with all local ordinances, making the most of your available space while adhering to city standards. These regulations are designed to encourage ADU construction throughout the city.
Building an ADU in San Jose typically takes 8 to 14 months from initial design to final inspection, depending on the complexity and city permit processing times. The design and permitting phase usually accounts for 3-6 months, as we navigate San Jose's specific review processes and ensure all plans meet local codes. Construction itself often takes 5-8 months, influenced by factors like weather, material availability, and the specific site conditions, such as managing potential drainage issues common in our area. We work efficiently to keep your project moving forward, providing clear timelines and managing expectations throughout the build.
No, current San Jose regulations do not require the homeowner to live in either the primary residence or the ADU. This means you have flexibility to rent out both units if you choose, which is a significant advantage for property owners looking to maximize rental income. This change in policy has made ADUs an even more attractive investment for San Jose homeowners. We can discuss how this flexibility impacts your specific property and investment goals, ensuring you understand all the options available to you.
For ADUs in San Jose, a reinforced concrete slab-on-grade foundation is often the most suitable and cost-effective choice, especially given our region's expansive clay soils. This type of foundation provides excellent stability and helps mitigate issues related to soil movement, which is a common consideration in many San Jose neighborhoods. In some cases, particularly on sloped lots or where specific soil reports indicate, a raised foundation or pier-and-beam system might be recommended. We conduct thorough site evaluations and soil analysis to determine the optimal foundation solution for your specific property, ensuring long-term structural integrity for your ADU.
