How Long It Takes to Build a Custom Home

How Long Does It Take to Build a Custom Home?

A new custom home takes 14 to 20 months from signed contract to completion in our market, and a whole-home remodel 9 to 14 months. Design and pricing come before the contract and add time of their own. When comparing schedules, ask each builder to name the start and finish points.

So here is the whole journey counted honestly, phase by phase, using current federal data where it exists and our own ranges where the data stops.

Ask how much time to allow for design and pricing before the construction contract.

How Long Does Construction Take, According to Census Data?

Among contractor-built single-family homes completed in the South in 2025, 57 percent took seven months or more from construction start to completion. The U.S. Census Bureau counts 12 percent finished within three months, 31 percent at four to six months, 22 percent at seven to nine, 16 percent at ten to twelve, and 19 percent at thirteen months or more.

That cuts both ways: 43 percent of contractor-built homes finished within six months, while 57 percent took seven months or longer, and 35 percent took ten months or longer. Census starts the clock when excavation for footings or foundations begins. Design, permitting, and site preparation completed before that point are outside the count.

Our 14 to 20 months is not directly comparable to those figures. It runs from the signed contract to handover, so it covers the approvals and site work scheduled after signing as well as construction itself, while the Census clock starts only when physical construction does. Design and pricing are finished before our contract, as our four-stage process sets out.

What Are the Phases of a Custom Home Build?

A custom home build runs in three phases: preconstruction, construction, and completion. Preconstruction covers feasibility, design, engineering, pricing, financing, and permits, and the design and the priced proposal are finished before you sign.

On Hill Country acreage the county process adds real steps: unincorporated Hays County requires a development permit, covered construction requires at least three third-party inspections, and a septic system is permitted and designed around your specific parcel. Neither Hays nor Travis County publishes a fixed review timeline, so we sequence the steps and carry the follow-up rather than promising dates the county never gave us.

Construction: site work, foundation, framing, rough-ins, finishes, and inspections, in that order, each gated by the one before it. This is the stretch those federal numbers describe.

Completion: punch list, final inspections, and walkthrough. The last stretch of finish work protects everything built before it, and rushing it is how punch list items turn into warranty claims.

What Delays a Custom Home Build?

Late selections, mid-build changes, weather, hidden site conditions, and long-lead materials can delay a build. Every one of those is real, and several get smaller when selections are locked to the build schedule instead of being made as they come up, which is how we run every project.

Our process pins selections to the build schedule, which keeps the site and the decisions from waiting on each other. Change orders get priced in writing before work moves. And the parcel gets read on the first walk, because rock found in month one is a budget line and rock found in month seven is a change order.

One real example instead of a promise: our San Marcos whole-home renovation ran 16 months, documented start to finish, for a complete transformation.
