From planning and permits to construction and final completion, J&C Contractors helps Seattle and Eastside homeowners navigate the entire new construction process with confidence — custom homes, ADUs, detached structures, and ground-up residential builds.
The right home rarely exists on the market. Build the one you actually want — engineered, permitted, and constructed under a single accountable GC.
How J&C Helps
Stop touring compromises. We build the home around your lot, your lifestyle, and the way your family actually uses space — instead of forcing your life into someone else's floor plan.
How J&C Helps
Ceiling heights, room sizes, window placement, kitchen flow, primary suite location — all decided up front and engineered into the plans, not retrofitted after the fact.
How J&C Helps
Finishes, fixtures, cabinetry, lighting, and structural choices are made deliberately — with samples, renderings, and line-item proposals before construction starts.
How J&C Helps
Home office, multi-gen suites, EV charging, smart-home wiring, solar-ready electrical — designed in from day one, not patched in later.
How J&C Helps
J&C runs the entire pre-construction stack — architect coordination, structural engineering, energy calcs, and jurisdictional permit submittal — so you're never managing it alone.
Real J&C new construction projects — custom homes, ADUs, detached structures, and ground-up expansions.
We build the full range of ground-up residential projects — engineered, permitted, and delivered under one GC. Tap any card for what we typically include in scope.

Every build begins long before the first wall goes up. Here’s how an idea becomes a stamped, engineered, permitted set of plans.
Step 01
Lifestyle goals, must-haves, and the home you actually want to live in.
Step 02
Lot review, zoning, setbacks, budget framework, and rough square-footage targets.
Step 03
Floor plans, elevations, and finish schedules developed with our architects.
Step 04
Structural, mechanical, and energy engineering — sized for the final design, not the rough draft.
Step 05
Full submittal, revisions, and jurisdictional approval through every required department.
Step 06
Site prep, utility staging, material orders, and trade scheduling locked before kickoff.
Most of the success of a new construction project is decided before construction even starts. We treat pre-construction as its own phase — with the same rigor as the build itself.
Lot survey, soil report, drainage, slope, setbacks, easements, and access — checked before design dollars are spent.
Line-item proposals broken into structure, mechanicals, finishes, fixtures, and contingencies — with realistic Eastside cost data.
Architectural plans developed in-house or with vetted partners — and reviewed for buildability before submittal.
Structural, mechanical, energy, and civil engineering coordinated under one schedule.
Full permit packages submitted to Seattle, Bellevue, Kirkland, Redmond, Bothell, and surrounding jurisdictions.
Construction calendar built around permit timelines, lead times, weather windows, and trade availability.
Cabinets, tile, stone, plumbing, lighting, and finish materials ordered before construction starts.
On-site visit, lifestyle conversation, and rough scope of the build — including lot, budget, and timeline.
Floor plans, elevations, lighting plans, finish schedules, and 3D renderings developed and finalized.
Stamped architectural and structural drawings, energy calcs, and full permit submittal through your jurisdiction.
Survey staking, excavation, foundation, utility tie-ins, and erosion control before vertical construction begins.
Foundation, framing, dry-in, mechanicals, drywall, finishes, and millwork — managed by one accountable project manager.
Punch list, jurisdiction final, documented finish schedule, and a written 5-Year Workmanship Warranty.
Architects, engineers, permit office, trades, inspectors, and finish suppliers — coordinated under one schedule and one accountable project manager.
Hundreds of completed Seattle-area builds under one licensed GC — including ground-up homes, ADUs, and detached structures.
One project manager owns the entire schedule — architects, engineers, trades, inspectors, and finish suppliers.
Architectural and structural drawings developed in-house or with vetted partners — reviewed for buildability before submittal.
Full submittal, revisions, and inspections handled through every Eastside jurisdiction we work in.
Single point of accountability across framing, mechanicals, drywall, finish, and final punch list.
Trim, millwork, tile, and finish work executed by long-tenured craftspeople — not subbed to the lowest bidder.
Every build is backed by a written 5-Year Workmanship Warranty plus manufacturer warranties on installed product.
Repeat clients and referrals across Seattle, Bellevue, Kirkland, Redmond, Mercer Island, and Medina.
