What a custom home build actually takes, from a builder who runs it himself.
Six to nine months. Two hundred to four hundred decisions. Three big budget categories. Here is what to expect on a custom home build in Dubuque, Jackson, Clinton, and surrounding counties.
The most common question we get from customers thinking about a custom home build is some version of, “How long is this actually going to take, and what does it actually cost?” The honest answer is: longer than the YouTube videos say, and more decisions than you think. But not unreasonably so. Most of our custom home builds in eastern Iowa run six to nine months from groundbreaking to keys-in-hand, and the per-finished-square-foot cost is set by your finish level.
Phase 1: Site walk through design, one to three months
Before we break ground, we spend somewhere between four weeks and three months on the front end of the project. That includes the site walk on your land, the floor plan iteration with you, the materials and finishes conversation, and the fixed-price written estimate. If your land needs a perc test for septic, that adds time. If you already have plans drawn, that subtracts time.
The longest part of this phase is usually the floor plan iteration. Most of our customers come in with a strong vision for two or three rooms (the kitchen, the primary suite, the great room) and a fuzzy sense of everything else. Drawing the plan together, walking through the layout in three dimensions, and figuring out where the windows actually go takes time. We do not push you through it fast.
Phase 2: Permits and foundation, four to eight weeks
Once plans are signed and the contract is in place, we pull the building permit. In our service area, that typically takes two to four weeks to come back through the county. We handle the paperwork. While the permit is in process, we mobilize the site: clearing, grading, driveway access if you do not already have one, and the staking for the foundation.
Foundation work starts the day the permit clears. Excavation, footings, foundation walls, and the slab pour usually take three to five weeks depending on weather and concrete cure time. We do not start framing until the foundation is square, level, and properly cured. Trying to skip that wait is the single most common shortcut in residential construction, and it shows up later as cracking, settling, and squared-off corners that no longer square.
Phase 3: Framing through dry-in, six to ten weeks
Framing is the most visible phase of the build. The house goes from a foundation to a structure with walls and a roof. We frame the walls, set the engineered trusses, sheath the exterior, install the windows and exterior doors, and get the roof on. The day we finish the roof and call it “dry-in” is the day the build feels real to most customers.
Eastern Iowa weather drives the schedule here. We try to get a winter build to dry-in by Thanksgiving so we can finish the interior through the cold months without weather-related delays. A spring or summer build follows the weather and usually moves faster.
Phase 4: Mechanical and finish, eight to sixteen weeks
Once the building is dry, the mechanical trades come through: electrical rough-in, plumbing rough-in, HVAC ducting and equipment. Then insulation, drywall, paint, trim, flooring, cabinets, countertops, fixtures, and final electrical and plumbing trim. Each of those steps depends on the one before it. This is the longest single phase of the build because there is the most coordination.
The two things that move this phase the most are material lead times and customer decisions. If your custom-order cabinets take fourteen weeks to deliver, that drives the schedule. If you change your mind about the kitchen layout halfway through, that drives the schedule even more. We try to lock the major finish decisions before framing starts so we can order long-lead items early.
Phase 5: Final walk-through, one week
After the final inspection clears, Collin walks the build with you, room by room. We document the punch list (the small finish items that need touch-up or correction), resolve them within the week, and hand you the keys. The warranty starts the day you move in.
How the budget actually splits up
For most of our eastern Iowa custom homes, the budget rolls up roughly like this: about 12 to 15 percent goes to permits, site prep, and the foundation. About 35 to 40 percent goes to the structural shell (framing, sheathing, roofing, siding, windows, exterior doors). About 25 to 30 percent goes to mechanicals (electrical, plumbing, HVAC). And the remaining 20 to 25 percent goes to interior finishes (drywall, paint, trim, flooring, cabinets, fixtures).
The variable that moves the per-square-foot cost the most is the interior finish level. A 2,400 square foot custom home with standard finishes (laminate flooring, painted MDF trim, builder-grade fixtures) lands at the low end of the range. The same footprint with hardwood flooring, custom cabinetry, and high-end fixtures lands at the high end.
The version of this that includes you
Every custom home is its own conversation. The timeline above is a typical range, not a promise. Some builds are faster, some are slower, and the difference usually comes down to weather, material lead times, and how many decisions you change in the middle of the build.
