Why Framework First

We build the home. You move in.

Most ADU companies hand you off to architects, contractors, permit consultants, lenders. We don't. One contract, one family, one finished home in your yard.

  1. Family-owned and operated

    Cathy, Austin, Joshua, and Eric oversee, train, and build the team that turns your ADU into a reality.

  2. Decades of craftsmanship

    Every crew trains on current building codes and safety procedures under Eric, our Craftsman Trainer with 40+ years in the trades.

  3. Our own factory, not a marketplace

    Climate-controlled, with 2x6 exterior walls, 50% thicker than 2x4. Built to CALGreen and Title 24 energy standards. No weather damage. Vetted professionals on your property only when the work calls for them.

  4. Full-project pricing, in writing

    One project price covers the build, foundation, crane delivery, utility transfers, appliances, and final inspections, with a permitting budget built in. Your feasibility study confirms costs specific to your lot, like septic or site work.

  5. Step inside before you buy

    Walk our Salinas factory and see homes at every stage of the build. We'll show you exactly what's behind the walls, insulation, wiring, framing, so you know what you're buying before you buy it.

  6. Delivered in as little as 4 months

    Site-built ADUs take 16 to 24 months. Ours are delivered in a day and installed within one to two weeks, subject to site conditions and local permitting.

One Home, Every Chapter

This is the house that grows with your family.

Your price is confirmed in your feasibility study and locks when you sign your build contract.

  • “I appreciated the information and advice that Alex shared with me in our phone consultation, even though it turns out I don’t have room in my yard for an ADU because of the County sewer line easement. He discussed other options I might have not involving their firm, which I thought was very courteous and helpful.”

  • “Framework First ADU’s is a local, family owned business in Monterey County. They also serve Santa Cruz and San Benito Counties. My experience from the beginning has been a very positive experience. If one is serious about an addition for oneself, family or a rental property, this is a great choice! Time is not a factor because of weather because the building of the ADU’s is done inside of a massive warehouse. One can walk through and get the visual of exactly what you want. The accessories/appliances are top notch; the countertops are a beautiful quartz. The layouts are practical. No space is wasted but useful and thoughtfully planned. If there is something additional that one needs, it can be done. Communication is key as well as transparency throughout the process. This is what I experienced throughout my time with Cathy. She’s smart, professional, creative and very transparent. I have referred others and will continue to do so.”

  • “Cathy, an incredibly knowledgeable expert, shared a plethora of options for a project that would assist me in my future build. Her extensive knowledge of the coastal zone where my property is situated was evident, and she answered all of my questions. Our phone conversation was highly informative, and I gained a better understanding of ADUs, planning, and building requirements. I recommend Framework First as your go-to for ADU’s. Be on the lookout for new models including a two story sometime soon.”

Cathy was wonderful to work with — professional, responsive, and genuinely committed to making sure every detail was taken care of. The quality of the work exceeded our expectations, and the entire process was smooth from start to finish. We are so grateful to Cathy and her team for helping us bring this project to life. Highly recommend Frame Works First to anyone looking for excellent service and beautiful results!. Jim and Sherry Khatibi”

The owner was helping me with my plans and helped me with ideas to save money when making my plans and how to approach my ideas. Awesome!! You’re in great hands with these guys. I just wish I had enough space on my property to have and ADU made and placed on my property. Im bummed…Yes, most definitely I’d go with Frameworkfirst. Christine Jenkins”

We went through both Framework options as well as potential Contractor method as well as both for my garage conversion and the option to leave it and build a smaller studio unit. We also touched on how in my situation how an ADU into a condo conversion and sale may look like. Really appreciate her knowledge of current laws and how to go about them and maybe ultimately lead me back to the ADUs Framework has to offer. I look forward to circling back to Cathy and Framework for my potential future ADU project”

Questions, Answered

The things every family asks first.

How much does a Framework First ADU cost?

Our homes range from $199,000 for a 450 square-foot studio to $599,000 for a 1,200 square-foot U-shaped 3-bedroom. Every price is all-inclusive, with a permitting budget built in along with plans, foundation, the factory build, delivery, hookups, appliances, and final inspection. Permit costs are set by your city or county, so they're property-specific and confirmed during your feasibility study.

How long does it take?

Four months is best case on our Four Fifty, our smallest model. Most ADUs are delivered in 4 to 6 months from contract signing, and our largest 1,200 square-foot homes take 7 to 9 months, subject to local permitting. We build 97% of the home in our Salinas factory in parallel with the foundation work.

What's included in the price?

A permitting budget and paperwork, site plan and Title 24, project management, the unit and all finish work, foundation work, appliances and custom cabinets, crane delivery and transportation, entrance and deck installation, and status updates by text and email. Permit costs are set by each city and county, so they're property-specific and confirmed in your feasibility study.

Do you finance?

We don't lend directly. We partner with two specialized ADU lenders, Mason Mac and SearchLight Lending. Most clients borrow against their existing home's equity. We can introduce you.

Where do you build?

Our core area is the tri-county region of Monterey, Santa Cruz, and San Benito counties, plus Santa Clara County where we do most of our work, including San Jose, Los Gatos, Morgan Hill, Watsonville, Los Altos, Marina, Monterey, and Carmel. We also take San Luis Obispo projects case by case.
