ADU Construction in Utah County

Accessory dwelling units can add flexible living space, rental potential, or a practical option for multigenerational living. They also require careful planning around setbacks, utility connections, parking, access, structure, and finish expectations.

Platypus helps Utah County property owners think through the full ADU path before construction begins, so the project starts with realistic plans and fewer surprises.

ADU Planning Considerations

  • Detached, attached, garage-conversion, or basement ADU feasibility.
  • Site access, grading, utilities, drainage, and concrete needs.
  • Structural and code considerations during design and engineering.
  • Construction sequencing that limits disruption where possible.

A Better Way to Start an ADU

The right ADU plan should fit the property, the intended use, and the budget. Bringing design, engineering, and construction together early helps prevent plans that look good on paper but become expensive to execute.

FAQ

ADU Builder in Utah County Questions

Can you help decide what type of ADU works for my property?

Yes. Platypus can review your goals, property conditions, and likely construction needs before recommending a direction.

Do ADUs need engineering?

Many ADU projects involve structural, site, or utility questions where engineering input is valuable before construction starts.

Can you build an ADU if another designer made the plans?

Often, yes. The team can review existing plans for constructability, scope, and budget alignment.

What Our Clients Say

Real Projects. Real People.
Real Results.

We let our work — and our clients — speak for us. Here's what homeowners and business owners have to say about working with Platypus Design & Construction.

"I am more than satisfied with the excellent work Platypus Design and Construction recently did for us. After a windstorm blew down a portion of our vinyl fence, he not only repaired the fence but saw what needed to be done to secure it so it would withstand future storms. He performed the work quickly, efficiently, and skillfully. The result was excellent and the cost was reasonable. We also appreciate the clarity and friendliness of all his communications and interactions with us. Overall, he did a superb job, even exceeding our expectations."

"McKay and his team have done multiple TI buildout projects for me and my Scenthound locations. They have been great to work with through everything to help me get a mix of great pricing, service, and overall product delivery. They are honest with their work and will ensure they take care of you as their client. Further, being able to use them for both design drawing, engineering, and the project buildout and management has saved me tens of thousands of dollars and weeks of time during my buildouts to have it all done with them in house. Platypus will continue to be my go-to for all my future commercial construction needs."
Spencer S. Commercial Build-Out
"We had an outstanding experience working with McKay Harper and Platypus Construction on a garage addition and a custom pergola over our patio. From the beginning, McKay demonstrated a high level of craftsmanship and attention to detail - he was able to match the existing architecture of our home seamlessly, to the point that the addition looks like it has always been there. It was a unique design challenge, and McKay used thoughtful engineering to create a beautiful freestanding structure that feels both solid and elegant. His pricing was very fair, and we would give McKay and Platypus Construction our highest recommendation and would absolutely work with him again."
