How building a custom home works

Six stages from empty lot to move-in day. Tap a stage to see what happens and what to decide.

Stage 1 of 6

Land & feasibility

Find or confirm the lot, then check what can actually be built on it before you commit.

  • Zoning, setbacks and deed restrictions
  • Flood zone and drainage
  • Utilities: city water and sewer, MUD, or well and septic
  • Soil and foundation considerations
  • Access, easements and HOA architectural rules

Building in your part of DFW

Choose the county and whether the lot is inside a city or on rural land. Requirements change with both.

Where is the lot?
Collin County

The fastest-growing county in the metroplex — newer construction, master-planned communities, and top-rated school districts.

Inside a Collin County city, the city handles permits and inspections and usually provides water and sewer. Ask the city's development office about zoning, setbacks and impact fees for your lot.
Cities to consider:McKinney, Plano, Frisco, Allen, Prosper, Celina

Expansive clay soil

Much of North Texas sits on clay that swells and shrinks. Foundations are usually engineered for the specific lot, so ask for a soils report.

Flood zones & drainage

Check FEMA flood maps and how water drains on the lot. It affects site work, elevation and insurance.

Utilities

Inside cities you typically connect to municipal water and sewer. Outside them you may need a well, septic system or a MUD, each with its own approvals and cost.

Permits & jurisdiction

A lot in a city follows that city’s permits and inspections. Unincorporated land is handled through the county. Which one applies changes the process.

HOA & builder rules

Many communities require architectural approval or a specific builder list. Confirm before you buy the lot.

Lot size & setbacks

Setbacks and easements reduce the buildable area. A large lot does not always mean a large house.

Budget planner

A planning tool, not a quote. Set the cost per square foot to match the finish level and bids you are getting.

Home size3,200 sq ft
Construction cost per sq ft$275

Example figure only. Finishes, plan complexity and the market move this a lot. Replace it with your builder’s numbers.

Lot budget$150,000

Set to $0 if you already own the lot.

Site work covers clearing, utilities, driveway and permits, and it varies a lot by lot. A contingency of 10 to 20 percent is common because final costs often run above early estimates.

Common questions

What people worry about most before building.

Final costs commonly run above early estimates, so plan a contingency of roughly 10 to 20 percent. The usual causes are changes after construction starts, upgrades beyond the allowances, material price swings and site surprises such as soil or utilities.
