Mountainside Construction LLC is a general contractor based in Hayden, Idaho, taking on residential construction work in and around Hayden and the surrounding Coeur d'Alene area. The business holds a current Idaho contractor registration through the Division of Occupational and Professional Licensing and works within a radius of roughly twenty-five miles of its Hayden base, which covers the towns along the Highway 95 corridor and the lakeside neighborhoods north of Coeur d'Alene.

As a general contractor, Mountainside Construction coordinates building work rather than a single trade, the kind of firm that pulls carpentry, framing and the subcontractors together on one job. It is registered in Idaho only, so its work stays on the Idaho side of the state line, in places like Hayden, Hayden Lake, Dalton Gardens, Rathdrum and Coeur d'Alene. The business registered with the state in 2023. General contracting covers a wide span, and the right hire depends on the size of the job. A quick fix, such as a rotted deck board, a sticking door or a small patch of drywall, rarely needs a general contractor at all; a handyman or the single trade involved is usually faster. A larger project, such as an addition, a kitchen that moves walls or plumbing, or a garage build, is where a general contractor earns its place, because someone has to sequence the trades, handle the permit with the city or Kootenai County, and keep the schedule moving around North Idaho's short building season. For bigger work, ask how the contractor manages subcontractors, who pulls the permit, and how changes to the scope get priced and written down before they happen.
