What to Expect During Your Build Timeline With Bilmar Homes
How Long Does a Custom Home Actually Take in Texas?
Statewide, a typical Texas custom home runs about 9 to 14 months from signed contract to move-in, with the construction phase itself averaging roughly 7.7 months nationally. That’s the number most builders quote. But it only tells part of the story: once you count the full pre-construction process — design, engineering, permitting, and finish selections — before the first shovel even goes in the ground, industry-wide figures for a fully custom home commonly stretch to 18–30 months start to finish. The gap between those two numbers comes down to one thing: how much of the design and decision-making happens before construction starts versus during it. That’s the single biggest factor in how long any build takes — and it’s exactly where Bilmar’s own process makes the biggest difference (more on that below).The Phases, in Order
- Permitting & pre-construction (roughly 1–8 weeks once plans are finalized) — site survey, soil testing, engineered plans, permit submission, loan closing, and finish selections.
- Site prep & foundation (roughly 9–12 weeks) — lot clearing, forms and rebar, plumbing stub-outs, concrete pour and cure time.
- Framing & weatherproofing (roughly 13–20 weeks) — walls, floors, roof, windows, doors, house wrap, and roofing, getting the home “dried in.”
- Mechanical rough-in (roughly 21–28 weeks) — plumbing, electrical, and HVAC lines run, insulation, and drywall prep.
- Drywall & interior finishes (roughly 29–42 weeks) — drywall, trim, cabinets, countertops, tile, flooring, paint, and appliances.
- Closeout (roughly 43–48 weeks) — punch list, final inspections, and certificate of occupancy.
What Commonly Causes Delays
- Late or changing selections — widely cited as the single biggest killer of build timelines, since every change after construction starts can ripple through later phases.
- Material lead times and supply chain issues — custom cabinets, windows, and specialty materials can carry 8–16 week lead times on their own.
- Permitting and municipal approval delays, especially in fast-growing areas.
- Labor and subcontractor scheduling conflicts, particularly for skilled trades booked months out.
- Weather — Gulf Coast builds in particular deal with heavy rainfall, humidity, and hurricane season (June through November), which can extend drywall and paint drying times and is worth budgeting a real weather contingency around, not treating as a rare exception.
- Financing friction — delays in construction loan draw approvals between phases (see our post on how construction financing works).
