Accessory Dwelling Units (ADUs)

An Accessory Dwelling Unit (ADU) is a secondary dwelling on a property that already has a house.

ADUs are ideal for generating income through long- or short-term rental, living small, multi-generational living, and aging in place. They have everything your house has: full kitchen & bath, laundry, heating & cooling, living space, and a sleeping area. Each of our ADUs is Earth Advantage Certified: Platinum.

What Sets SQFT Studios Apart?

Our Buildings are Prefabricated and Modular

We’ve developed a proprietary modular building system to achieve beautiful design and maximize efficiency. This helps to lower cost and production time while increasing quality.

Our Buildings are Sustainable

We utilize Advanced Framing Techniques, use only FSC Certified lumber and sheathing, install metal roofs that can be recycled, and use low- or no-VOC finishes. We are constantly researching and implementing building methods and products that are sustainable and healthy.

Our Buildings are High Quality

We build our buildings knowing they will be standing for the next 100+ years. It is a quality building that will last and provide utility for years to come with minimal maintenance and upkeep.

Our Buildings are Turn-key

We take care of virtually everything along the way. Design, permitting, build, subcontractors, inspections, etc. Heck, you could live halfway around the world and we could take care of the entire project for you.

SQFT Studios Exercises its Values
with Each and Every Building we Create


Always be creating; objects, ideas, memories, friends, greatness.


The old adage, “Do it right the first time” still applies today.


“Do what you say you’ll do.”


Leave this world cleaner and better than you found it.


Designing and building something should be fun – and we love doing this.


Treat everyone (client, employee, vendor, and self) with kindness, understanding, and gratitude.

Love what you do

We are passionate about what we do and love working with others who are equally passionate.


“SQFT Studios became the answer to our problems – [My husband] Jason needed a bigger, more private space to do his photography work and meet with clients, and our small house was not going to cut it anymore. A casual conversation with SQFT Studios turned into creative, yet functional building plans, and these hard-working gentlemen hit the ground running. They had the structure built in less than a month, and we are so happy with the result. SQFT Studios are professional, determined, and personable, and we feel lucky to have found them.”

ADU Owner

“Our ADU is beautiful. Everyone who has seen it has something nice to say about it. The design process with SQFT’s architect, Eli Green, though conducted remotely, was still intimate, accessible, and thoughtful. It never felt rushed, and he addressed even our smallest concerns in order to give us the product that we wanted. SQFT Stuios was committed to our vision for the project, and they take pride in what they build while maintaining an interest in our personal needs. Thank you, SQFT Studios.”

“I was really impressed with the quality of your work. Everywhere I looked, things were done ‘as they should be.’ In the few small cases where something needed fixing, you took care of it promptly and cheerfully, which is a value I really respect in people I’ve hired to do things for me. In particular, I have to say, the carpentry is second to none.”
