Scope of Work

What a Home Addition Includes

One accountable general contractor handling every phase, design, foundation, framing, trades, tie-in, and finishes.

Design & Engineering

Layout, elevations, and stamped structural plans, coordinated with architects and engineers we trust.

Foundation Work

Footings, stem walls, crawl space, or slab, properly sized for the addition's loads and Idaho frost depth.

Framing & Roof Tie-In

Walls, floor systems, roof rafters or trusses, and clean tie-ins that match existing roof lines.

Second-Story Additions

Load analysis, reinforced framing, stair placement, and weather-sealed tie-ins for popping a new floor up top.

Plumbing, Electrical & HVAC

Extending existing systems to the new space, bathrooms, kitchens, heating and cooling, and dedicated circuits.

Matching Exteriors

Siding, trim, roofing, and windows matched to the existing home so the addition doesn't look bolted on.

Interior Finish

Drywall, trim, doors, flooring, paint, and cabinetry tied into the existing interior style.

Permits & Inspections

Idaho and Washington building permits pulled, and every inspection coordinated for you.

Local Experience

Three Decades of Building Additions in Northern Idaho

Chuck and Norm Kile have been building home additions across the Coeur d'Alene region for more than 30 years. We've built bedroom bump-outs, master suites, second stories, sun rooms, garage conversions, and full in-law suites, and we know what features add real value at resale and what structural details are worth doing right.

We also know the ins and outs of local setbacks, zoning, and the Idaho and Washington permitting processes, all of which can become real headaches without experience. Bring us your plans and drawings, or start from a blank page, we'll help you scope the addition, estimate the cost, and build it the way you actually want.

Kile Construction is a full-service residential general contractor. From a small bump-out to a full second floor, it's like having your own personal builder ready to customize your home exactly to your liking.

FAQ

Home Addition Questions

Straight answers to what homeowners ask most before adding on.

How long does a home addition take?
Most room additions run 3–6 months from foundation to finish. Second-story additions and larger in-law suites can take 4–8 months depending on scope, weather, and permitting timelines. You'll get a written schedule with your estimate.
Will an addition match the rest of my house?
Yes, that's the goal. We match roof lines, siding, trim profiles, windows, and interior finishes so the addition reads as part of the original house, not an obvious bolt-on. For older homes with discontinued materials, we source the closest match available.
Do I need an architect or engineer?
Most additions require stamped structural plans from an engineer, and larger projects benefit from architectural drawings. We coordinate with local architects and engineers we trust, or build from your drawings if you already have them.
Can I stay in my home during the addition?
Yes, in almost every case. We seal off the tie-in wall, control dust, and only open the connection between old and new when we're ready to work there. For second-story additions that require temporary roof work, we plan for weather.
Can you build a second-story addition or garage conversion?
Yes. Second stories, over-garage bonus rooms, garage-to-living conversions, and detached ADUs are all common projects. Each has its own structural, egress, and code considerations, we manage all of it.
Do you pull permits and handle inspections?
Yes. As your general contractor we pull all required Idaho or Washington building permits and coordinate every inspection. Call (208) 660-2470 or request a meeting online to get started.
