We focus on the elemental principles of superior design that compliments all phases of one’s life – whether you are a new family, or an emptynester, or anywhere in between – you’ll find your home in a Cotner home.


Our focus is to build quality into every home and planned community. We use only seasoned craftsman, reputable subcontractors and the finest construction materials to build our homes. You will not find a builder with more emphasis on quality, amenities, service and an unwavering attention to the smallest of details.


We build value into every home with a variety of architectural styles, aesthetic upgrades, designer color schemes, modern floor plans, amenities and much more to enhance your life.


Cotner Building Company has been in business since the late ’90’s and our management team has decades of experience in the Treasure Valley housing market. We know and understand the trends and priorities of the communities where we call home.

We Do What We Say We’re Going to Do

Responsive customer service is not a buzzword. We work hard every day to deliver the quality, service and value we promise to all of our customers. In fact, we think of ourselves as a “service company,” that builds homes and communities. We’ll earn your business before, during and after the sale.

Something for Everyone

Our communities feature convenient locations, great floor plans, professional décor and styling, a true feeling of community, and a comfortable touch of style and elegance that set them apart.
