Barndominium Builders in Farmersville, TX

Barndominium builders who work in Farmersville are building in some of the most rural country left in Collin County. Farmersville sits in the northeast part of the county, about 45 miles from Dallas, and stayed small while other towns boomed: 3,301 people in 2010 and 3,612 in 2020. U.S. Route 380 crosses the south side of town, running 18 miles west to McKinney and 15 miles east to Greenville, and State Highway 78 passes along the west side, 10 miles north to Blue Ridge and 27 miles southwest to Garland.

A town square with deep roots

Farmersville started in 1849 as a settlement on the Jefferson-McKinney Road. William Gotcher donated land for the public square on March 4, 1859, and the town incorporated on June 2, 1873. In the 1930s it was known as the Onion Capital of North Texas, shipping more than 1,000 carloads of onions a year. Audie Murphy held a homecoming event here on June 15, 1945. At about 653 feet, the town sits higher than most of the Dallas area.

Wells change the acreage math

Out in the country around Farmersville, some owners plan on a water well. Under Collin County's septic rules, a well raises the land you need. For a lot divided in 2008 or later, the minimum is 1 usable acre without a well and 1.5 acres, with 1 usable, if there is one. Lots divided between 1983 and 2008 need 1 acre, or 1.5 acres with a well. Easements, ponds and similar areas generally do not count as usable. A farm tank that looks like a feature can shrink your buildable area.

Who designs the septic

Collin County requires a Registered Sanitarian or Professional Engineer to design a septic system, and projects must meet the state's Chapter 285 rules plus a county court order with additional, more stringent rules. Systems that need ongoing maintenance carry an affidavit filed with the County Clerk at 2300 Bloomdale Road in McKinney. If you ever sell a property with an aerobic system, the county asks for a change of ownership, an aerobic homeowner information sheet and a maintenance contract in the new owner's name. We coordinate the designer's work with the house plan so the drain field ends up where it should.

Lavon Lake at the city limits

The northern end of Lavon Lake reaches the western city limits of Farmersville, on both sides of US 380. Land near the lake and the creeks feeding it can include floodplain. We check each parcel with Collin County's interactive maps, which show city limits, ETJ and floodplain status, before choosing a pad site.

Older lots and small tracts

Some land around an old town like Farmersville was divided decades ago. Collin County says a lot that existed at its small size before 1983 may still qualify for septic if you can document that and the system meets state and county rules, with a third-party evaluation to confirm. A lot that was cut down after the applicable dates is not eligible. We help you sort that out before you commit to a design.
