Why Caldwell Homeowners Work With Us

A building project has a lot of moving parts. Our job is to make it feel simple for you.

We start with a visit to your home. We listen to what you want, look at your lot and talk through ideas. Then we give you a clear plan with the scope, the timeline and the cost. Once you’re ready, we handle the permits and the build, and we keep you posted as we go.

Building in Caldwell: Permits and Local Rules

Caldwell is the county seat of Canyon County. The City of Caldwell’s Building Safety team has its own permit packets, including one just for home additions. Home permits there are submitted online. Outside city limits, Canyon County handles permits.

We take care of the paperwork, the plans and the inspections for you. If you’re in an HOA, we’ll help with their review too.
