San Jose ADU Permit Process — Step by Step
Site Assessment
We visit your property (or review via satellite + records) to confirm setbacks, lot coverage, utility connections, and zoning eligibility.
Plan Selection & Design
You select your ADU model and finishes. We prepare permit-ready plans stamped by a California-licensed engineer.
City Submittal
We submit to San Jose's Department of Planning, Building and Code Enforcement (PBCE). For pre-approved plans, processing typically takes 30–60 days.
Factory Build
While permits are in process, your ADU is built in our factory under HCD inspection. Build time: 8–12 weeks.
Delivery & Installation
Permitted? We deliver, set on foundation, connect utilities, and schedule final inspection. Move-in typically 4–6 weeks after permit approval.
Why San Jose Homeowners Are Adding ADUs Now
Rental Income
San Jose median asking rents for 1BR units exceed $2,800/month. An ADU typically achieves $2,500–$4,000+, depending on size and amenities.
Multi-Generational Living
Extended family housing is a major driver. A private ADU lets adult children or aging parents live on-site without sharing living space.
Property Value
Studies show ADUs add 20–35% to San Jose property values — often more than the construction cost, especially in high-demand neighborhoods.
San Jose Modular Home FAQs
Does San Jose have a streamlined ADU permit process?
Yes. San Jose has one of the Bay Area's most homeowner-friendly ADU permit programs. Pre-approved ADU plans can be processed in as little as 30 days. Epic Modulars' HCD-certified units qualify for streamlined review, which means faster approvals and less back-and-forth with the planning department.
What are San Jose's ADU setback requirements?
San Jose follows California state minimums for ADU setbacks: 4 feet from rear and side property lines for detached ADUs up to 800 sq ft. Front setbacks match the primary dwelling's requirements. We assess your specific lot and confirm compliance during your free site evaluation.
How much does it cost to build an ADU in San Jose?
Epic Modulars ADUs in San Jose start at $79,000 all-in — permits, delivery, installation, and warranty included. Site-built ADUs in San Jose typically run $200,000–$400,000+ due to Silicon Valley labor rates. Our factory model cuts costs dramatically without cutting corners on quality.
What zoning allows ADUs in San Jose?
ADUs are allowed in all residential zones in San Jose — R-1 (single-family), R-2, R-3, and most mixed-use zones with residential components. California state law largely overrides local zoning restrictions for ADU development. The key variables are lot coverage, setbacks, and utility capacity.
Can I rent my ADU on Airbnb in San Jose?
San Jose allows short-term rentals (STR) but requires a permit and restricts STR operation to owner-occupied properties. If you're renting the primary home and want to rent the ADU short-term, additional rules apply. Long-term rental of an ADU has no owner-occupancy requirement under California law.
