HOME ADDITIONS & ADUS IN FLAGSTAFF
START YOUR ADDITION
Planning an addition or ADU starts with understanding how the new space needs to support your family, property, and long-term plans. Tell us what you’re considering, and we’ll help you define the right scope, budget, and next step with clarity.
ADDITIONS & ADUS
Whether you need a private suite for aging parents, a dedicated home office, a detached rental unit, or room for a growing family, HighQ brings design, pre-construction, permitting, and construction together under one accountable team. We plan the new space around your goals and your existing home so the addition feels intentional, functional, and built to belong.
Additions succeed when the new and existing structures are considered together from the start. Our pre-construction process coordinates design, engineering, HOA requirements, permits, selections, budget, and schedule early—helping the finished space integrate with your home instead of feeling added on.
CLIENT EXPERIENCE
Heinz W.
We used Evan and his team all the way from designing, permits from City and HOA (Pine Canyon), up to building our custom home. Evan was great to work with. He has helped tremendously by bringing in his own ideas and experience during the design process. With his knowledge, speed, and flexibility we were able to get through the approval process in record time. The team functions very well as a “big family”. They are very experienced, trustworthy, and honest people. Special kudos for building the house here in Flagstaff where labor and materials are sparse and expensive. They managed the project very well delivering on scope, cost, and quality. Overall, they did a great job, and we are extremely satisfied and happy with the “end-result”. Highly recommend HighQ!

We could not be more delighted and grateful for their kindness, exceptional work quality, and the attention to detail that everyone at HighQ gave to our project. We did our first project with Evan and his father about 13 years ago, and we hoped that we would receive the same level of quality and professionalism. Like fine wine, time only made this company better! From the moment that we met Taryn and Grant to discuss the possibilities and design of our project to the last inspection with Tom and Tim to “hammer out” final completion and details, we could not have been more pleased. They are the best, and we know that they will stand behind their work, which is such a wonderful feeling. There is no doubt in our mind if we ever decide to do construction work again, they are our team. We highly recommend them as contractors and as awesome humans.

We are extremely happy with the job done by HighQ. Cameron completed the work in a timely manner, provided a quality service at a fair price, was professional, and cleaned up the work area daily. He found additional water damage as he progressed through the project. Cameron communicated effectively and did everything in a professional manner. Additional charges were very reasonable for the work performed. We highly recommend him!

HighQ was wonderful and easy to work with. We highly recommend this company. They helped us through every step of our remodel. Taryn and team were great at communicating. They always responded in a timely manner to any questions we had. They listened to us and were helpful to offer a variety of solutions to whatever issue came up. They also were willing to make any corrections to items that weren’t exactly the way we wanted them. Without hesitation they came back and fixed the items we asked to have corrected. Remodeling can be a long, hard road and HighQ made it as uncomplicated as possible.

Perhaps the only negative would be that it took four months before HighQ could fit our project into their schedule but the wait was worth it. If we were to plan on another project at our home we would consider HighQ again.

From the planning to completion, the folks at HighQ were a true pleasure to work with. They were always professional and maintained good communication throughout. They had some really good suggestions that we implemented. And when we ran into a complication, I was so impressed with their resourcefulness and problem-solving. I completely trust them to stand by their work and would highly recommend them.

frequently asked questions
Adding space to an existing property raises important questions about cost, design, permitting, utilities, and how the new structure will connect to your home. These answers explain how HighQ approaches additions and ADUs in Northern Arizona.
How much does a home addition or ADU cost?
Cost depends on size, site conditions, foundation and structural requirements, utilities, finishes, and whether the space is attached or detached. A basic bedroom addition typically starts around $85,000, while larger or more complex additions and ADUs require a project-specific budget. During pre-construction, we define the scope and develop a realistic fixed construction price.
Can you help with design, engineering, and permits?
Yes. High Caliber is a design-build contractor, so we can coordinate as-built drawings, designers or architects, structural and wastewater engineering, HOA approvals, interior selections, City or County permits, budgeting, and construction through one accountable team.
Can an addition match our existing home?
Yes. Seamless integration is a central part of planning an addition. We consider rooflines, exterior materials, window placement, proportions, circulation, and interior finishes so the new space supports the original architecture rather than feeling like an afterthought.
What can an ADU or addition be used for?
Common uses include a primary suite, space for aging parents, a private guest suite, a home office, a long-term rental, a sunroom, or additional garage space. We help evaluate the property and local requirements so the design fits both your goals and the site.
