Make Better Use of the Property You Already Have
Your home may have more potential than you realize.
An ADU can create valuable additional living space for:
-
Aging parents or family members
-
Adult children
-
Long-term guests
-
A private home office
-
Rental income
-
Future caregiving needs
-
Flexible multi-generational living
But building an ADU involves much more than adding a room.
There are design decisions, zoning requirements, permits, utilities, structural considerations, and construction details that all need to work together.
Carey Bros. Design & Build Remodeling helps guide the entire process so you can move forward with confidence.

WORDS FROM OUR RAVING FANS
Mark W.
“I've known the Carey Bros. Design & Build Remodeling for over 3 years now, and together we have been through 3 large projects. James and Morris treat their work as though they were working on their own home. It’s extremely difficult to find a company that can produce high-quality workmanship consistently.”
Ken K.
The Carey Bros are the complete package. They do what they say they’re going to do. Safe. clean, and on time. They are above and beyond my expectations and I'm picky.
Edmund G.
“Their detailed thoroughness and preparation, the performance and attitude of their onsite crew, post-job clean-up and follow-through demonstrate not just professionalism and experience but love, a sincere care and passion for what they do.”
Phil C.
The quality of our lives has changes because of this home that we are able to enjoy. I think what stands out with Carey Bros. is that they really demonstrate their passion. It’s not just a job to them. Everyone was very focused. A lot of passion went into the project and a lot of pride.
John J.
We first hired the Carey Bros. Design & Build Remodeling in 1995 to remodel our 42 year old kitchen. Morris' wife Carol designed the new kitchen counter and cabinets. James and Morris then proceeded with the renovation in a professional manner, including cleaning up after each day's work. In May 2014, severe cracks occurred overnight in our living room ceiling and exterior stucco walls, apparently caused by drought-related earth movement. We called upon the Carey Bros. Design & Build Remodeling who did a thorough investigation, and who proceeded to correct the problem by installing screw jacks where needed underneath the house to level the floors. Here again the work was completed in a professional manner. We are highly pleased with their work.
Lillian B.
I've been enjoying my new Carey Bros Kitchen for the last year. It is a pleasure to walk into the light, bright space every day, The beauty of the cherry cabinets and the granite countertops are outstanding. The extra storage space in the drawer banks and pull out cabinets make a huge difference. The under cabinet lighting makes preparation and clean up a breeze. I highly recommend the Carey Bros remodeling team.
Tom R.
James and Morris were both great. They did everything efficiently and preplanned. There were no problems.
Neil L.
Awesome work, very professional. Matched everything perfectly, they went above and beyond my expectations.
Karen F.
My husband and I contacted Carey Bros. Design & Build Remodeling for our kitchen remodeling project. I have to say that everything from design to finished project was absolutely perfect. We worked with James for design and then Carol helped with design as far as products such as granite and tile backsplash and paint colors. Their communication was the best I've ever had from any contractor. Field Superintendent Matt was great to work with. Every night we received an email letting us know what was going on the next day and who would be at our house. All of the workers were very polite and courteous and kept a very clean workspace. This was the best contracting job we've ever had! Our project turned out beautiful and I would highly recommend Carey Bros. Design & Build Remodeling for any of your contracting jobs! You won't be disappointed!
Angie C.
It is our forever home. We didn’t think that we would have gotten the house without the remodel and it really has exceeded our expectations in every way possible. We spend every single day in the kitchen. Almost 70% of our time in the house is around that island, so it really has been a big part of our life and probably forever.

What is an ADU?
An Accessory Dwelling Unit, or ADU, is an additional residential living space located on the same property as a primary home. Depending on the property and project, an ADU may be attached, detached, or created by converting existing space.
What can an ADU be used for?
ADUs can be used for family members, guests, caregivers, adult children, home offices, long-term rental housing, or other flexible living arrangements.
Can I build an ADU in my backyard?
Many residential properties may qualify for a backyard ADU, but requirements depend on the property, lot, local regulations, utilities, and proposed design. We can help evaluate your property and project goals.
Do you build detached ADUs?
Yes. Detached ADUs can create a completely separate living space while still being located on the same property as the primary residence.
Can you convert my garage into an ADU?
Depending on the structure and local requirements, an existing garage may be a candidate for conversion into living space. The first step is evaluating the garage and property.
Can an ADU have a full kitchen and bathroom?
Yes. ADUs can be designed as complete independent living spaces with kitchens, bathrooms, bedrooms, living areas, and other residential features.
How much does it cost to build an ADU?
ADU costs vary significantly based on size, design, site conditions, utility work, structural requirements, finishes, and the type of ADU being built. We’ll discuss your goals and help you understand the expected investment.
How long does an ADU project take?
The timeline depends on design complexity, permits, approvals, site preparation, utilities, material availability, and construction. We’ll provide a project schedule based on your specific project.
Do ADUs require permits?
Yes, ADU construction typically requires local permits and approvals. Requirements vary by property and jurisdiction. Our team can help guide the project through the appropriate process.
Can I rent out my ADU?
Rental rules can vary by city and property. If rental income is one of your goals, it’s important to understand the local requirements that apply to your property.
Can you help design the ADU?
Yes. Our design-build process combines planning, design, and construction so the project is coordinated from the beginning.
Can you build an ADU for aging parents?
Yes. ADUs can be a great option for multi-generational living. We can discuss layouts and features that improve comfort, privacy, accessibility, and long-term usability.
Can you make an ADU accessible?
Yes. Depending on your goals, we can incorporate features such as easier-entry showers, wider pathways, improved lighting, accessible storage, and other aging-in-place considerations.
Will the ADU match my existing house?
It can. We can design the exterior to coordinate with your existing home or develop a complementary style that works with the property.
Do you handle the entire construction process?
Yes. Carey Bros. Design & Build Remodeling coordinates the project from planning and design through construction and completion.
