About this template

Building a custom home is the largest project most people ever run. The schedule is dominated by three things: how long the city takes to issue permits (1–4 months), how long the framing crew is on site (6–10 weeks), and how many decisions you can lock in before the slab is poured. This template covers a 14-month build of a single-family home on a buildable lot. Sub-divide it freely, since every region runs slightly different sequences.

How a 14-month custom build breaks down

Design and permits

Months 1–4

Architect produces schematic design, then construction documents. Engineer signs off on structural and energy compliance. Builder bids the plans, contract gets signed, and the plans go to the city for permit. Most cities take 6–16 weeks for a single-family permit; some take longer. Use this window to also finalize finish selections so they are ready when needed.

Site work and foundation

Months 5–6

Clear and grade the lot. Install temporary power and the construction water meter. Excavate footings. Pour foundation (slab or stem wall depending on region). Run underground plumbing. Backfill and compact. Foundation inspection before anything else goes up.

Framing and dry-in

Months 7–8

Framing crew sets the floor, walls, and roof. Sheathing goes on, roof felt and shingles, windows install, exterior doors hang. The house is "dried in" when rain no longer reaches the inside. Framing inspection signs off the structural work. This is the fastest visible progress phase. The house goes from foundation to recognizable structure in about 8 weeks.

Mechanical, electrical, plumbing

Months 9–10

Plumber, electrician, and HVAC contractor run pipes, wires, and ducts through the framed walls. Insulation goes in after MEP rough-in passes inspection. Drywall hang, tape, and finish takes 3–4 weeks for a typical 3,000 sq ft home.

Finishes and trim

Months 11–12

Paint primer, trim install, cabinets, countertops, tile, hardwood, paint final coats, doors hang, hardware installs. Plumbing and electrical "trim out": fixtures, faucets, light fixtures, switches. Appliances install. Exterior is also progressing: siding, paint, driveway, landscaping.

Closeout and move-in

Months 13–14

Final inspections, certificate of occupancy, final walkthrough with builder, punch list, landscaping, and move-in. Most builders offer a 1-year warranty walkthrough at the end of year 1.

Tips from finished custom builds

01 Lock in finish selections before the slab is poured. The first 30 questions in framing are about where things go, and changes after the framer is on site cost real money.
02 Visit the site every week, even when you think nothing is happening. The 15 minutes you spend on Tuesday catches the mistakes that would have been buried by Friday.
03 Build a 15% contingency into the budget. Custom builds rarely come in under contract; the budget should plan for that.
04 Schedule the final walkthrough during daylight hours. Defects you cannot see at 9pm are obvious at 11am.
05 Hold the final builder payment until the punch list is closed. Once the check clears, motivation to fix the last 5 items drops sharply.

Frequently asked questions

How long does it take to build a custom home?

10–18 months for most builds, depending on size, complexity, and permitting time. This template targets the 14-month middle case.

What is the most-missed risk?

Permit review time. Some jurisdictions issue in 6 weeks; others take 16. Ask the builder for the local average before you sign the contract.

When should I select finishes?

During design: before the slab is poured. Late selections become change orders and slow the schedule.
