California’s Senate Bill 9 opens up new possibilities for homeowners to do more with their existing property whether that means adding additional units, creating flexible living spaces, or exploring new income opportunities. At Urbatect, we specialize in navigating the complexities of SB 9 to help you split your lot or build on a single-family property.
From evaluating your property’s eligibility to handling design, permits, and construction, having a clear path forward makes all the difference in turning potential into a real, valuable outcome.
What is SB 9? And Does Your Property Qualify?
Signed into law to address California’s housing shortage, SB 9 allows eligible homeowners in single-family zones to unlock new development opportunities on their existing property.
- Urban Lot Splits — Divide one residential lot into two separate parcels, subject to eligibility and owner-occupancy requirements.
- Two-Unit Developments — Build up to two primary homes on a single lot, either attached or detached.
- Expanded Potential — Qualifying properties may support up to four total housing units where only one was previously allowed.
All SB 9 projects are reviewed ministerially, meaning a faster, more predictable approval process when requirements are met.
Does Your Property Qualify?
Your property may be eligible for SB 9 if it meets some of the following criteria:
- Located in a single-family residential zone
- Situated within an urbanized or developed area
- Meets minimum lot size and access requirements
- No recent tenant displacement from the property
- Not located in environmentally restricted or historic zones
- Able to comply with local development standards and setbacks

After speaking with several construction companies on getting a permitted ADU built at a property, Urbatect seemed to be the most organized and reasonable in terms of timeline, quality, and... read more cost. Special mention to John Soliz who gave a detailed explanation of the project timeline and really convinced me Urbatect was the right company for my needs. Also, the design project manager Akanksha has been amazing. Akanksha has been timely in getting different steps of the drawings/plans/permits finished and provided me with regular updates and additional information to keep me informed. I look forward to the construction phase and plan to update my review on that part of the process when it is finished.

3/26/2025I worked with Urbatech to plan the construction of an detached ADU in the backyard of my home. I had contacted several ADU construction companies to discuss the process... read more and cost. I found Urbatech to be the very best. My sales consultant, John Stoliz, was outstanding. He was very knowledgeable, patient, a great listener and was very customer focused. He carefully guided my wife and I through the planning process working closely with his team to develop a plan for construction that met our needs. We asked numerous questions and John always responded and did an outstanding job of informing/coaching us on how best to proceed based on our needs. John was always patient with us. We never felt rushed or under pressure to sign a contract. I enjoyed working with John and his team. Outstanding group. I found their pricing to be very competitive as well. I would highly recommend Urbatech for your ADU needs.

I was in a panic. I have been trying for 5 months to simply put in a window through hcd because I have a manufactured home. Endless delays. After being... read more told I could do a quick sketch and attach it to an email to get my permit, I was told that yet again the inspector wanted something else. An engineering stamp. I've put in Windows before and manufactured homes and never had to do this. Plus it was going to cost me $500. I almost think it is because I'm a retired widow. A person I contracted with said he knew someone and of course I didn't hear a word. So I just went out on my own and found Urbatect.com. I formulated a rather verbose text and thought I would probably not hear back from them. To my shock, I got a return email immediately. Not only that they also immediately provided an engineering stamp. I couldn't believe the fast service. Such a relief and I pray I can put my stupid window in at long last. I just moved to Paso Robles and I've been living with this wall in front of me all this time and the new window leaning on it waiting to go in. It's been driving me crazy! Thank you to this accommodating business that no doubt has many more important things to do than my engineering stamp! THANK YOU AGAIN
A MILLION TIMES OVER.

Although there was some variability in the people I worked with as a client to Urbatect, I'm going to focus my evaluation on the outstanding engineer I worked with, Jay.... read more He was definitely a bright spot in our experience with Urbatect. He was very competent and responsive. My particular build was an unusual build in that it combined mixing an 1800s barn structure with a modern, traditional framing to meet code. Jay did a great job of working with the two types of build. There were a few details that the builder needed that didn't seem to be in the plans but Jay has always been excellent about responding to those issues in a timely way. It was especially impressive because the build has been happening over time (still on-going), but Jay always seems familiar with the details. He definitely reflected a combination of friendliness and expertise. If you become a client of Urbatect, I highly recommend him as your engineer for your structural plans.
