A word from our founder
Growing up in a small town with limited housing, low quality builds, and the struggle of seeing homeowners struggle with construction projects is one of the big reasons why I founded Urbatect. After spending many years working for some of the top firms in the country, I understood the issues in the industry at both a small and large scale. I saw how overwhelming projects could be independently of the scale of the project especially when the clients are left juggling with designers, engineers, city approvals, and contractors on their own. I knew there had to be a better way to streamline the process and actually make it an enjoyable experience for clients including homeowners. Over the past 15+ years, we’ve delivered over 3,500 projects across California and Washington from ADUs and renovations to custom homes and multi-family developments by staying true to one mission: make the process clear, honest, and personal. With a fully integrated team, strategic and transparent approach, we’re here to guide you from the first conversation to turning over the keys for your project every step of the way. Our goal is to maximize the results for our clients while making this an enjoyable experience and minimizing their risk.

FAQs
1. How does the design-build home renovation process work in California?
With Urbatect’s design-build model, we manage your entire project under one contract design, permitting, and construction. This means fewer delays, better communication, and a smoother experience for California homeowners looking for ADU, remodel, expand, or build a home.
2. How can I keep my home renovation or ADU project on budget in California?
Urbatect offers a fixed-price contract early in the design phase. Our design and construction teams work together from day one to align your vision and your budget so you don’t face last-minute costs, change orders, or surprises during construction.
3. Do I need a permit to remodel my home, add a room, or build an ADU in California?
Yes, almost all remodeling, additions, and ADU projects in California require city permits. Urbatect handles the full permitting process from planning, drawings, and city submittals to construction so your project stays compliant and on track.
4. Is it better to hire a design-build firm or separate professional or contractor in California?
Working with a design-build firm like Urbatect gives you one team handling everything. That means better coordination, fewer delays, and more control over your budget unlike hiring a separate architect, engineer, and contractor who may not be aligned.
5. What’s the best option for my property: build an ADU, add a room, or remodel my home in California?
It depends on your space, budget, and long-term goals. Urbatect offers a custom feasibility study to help you decide. Whether you need more living space, rental income, or a layout upgrade we’ll help you choose the right solution for your home and property.
6. How long does a home remodel, room addition, or ADU project take in California?
Project timelines vary, but most remodels and ADUs in California take between 3 to 12 months. Urbatect’s all-in-one approach helps speed things up we handle design, permits, and construction in-house so you avoid unnecessary delays.
7. Can I hire Urbatect just for design services, or do you have pre-approved ADU plans?
Yes. We offer both custom design services and build ready ADU plans ready for permits. Whether you want a fully customized layout or a faster, more affordable plan, we help you choose what works best for your property and timeline.
