Midlothian was an industrial town long before it was a commuter suburb. Texas Industries finished its third cement kiln here in 1967 and became the largest cement operation in Texas, according to the City’s 2045 comprehensive plan. By the 1980s the town was billing itself as the “Cement Capitol of Texas,” the Handbook of Texas records, and in 2025 the local economic development office marked 50 years of steelmaking at the mill Gerdau bought from Chaparral Steel in 2007.
Now the houses are catching up with the kilns. The Census Bureau’s Vintage 2025 estimates count 46,683 people in Midlothian on July 1, 2025, up from a 2020 base of 35,063. A third more residents in five years, in a city that had 7,480 in 2000.
We’re MASACO Construction, a woman- and minority-owned general contractor at 7950 Legacy Drive in Plano. That’s about an hour north of downtown Midlothian, and we’ll say so plainly. Commercial work leads for us, with a full residential remodeling practice beside it.
We haven’t completed a project in Midlothian. Our nearest finished work is Pizza Twist in Irving, roughly 23 miles north as the crow flies. It’s a 2,000 square foot franchise restaurant, and the kitchen install and utility connections happened over 6 to 8 weeks with the dining room serving customers, because we phased the work around service hours.
Two highways and two railroads cut the city into quarters
The comprehensive plan describes two Class I railroads meeting near downtown: the Union Pacific running northwest to southeast and the BNSF running northeast to southwest. US 67 and US 287 cross the city as well, and the plan places business development along the highways, so most site searches start on one of those four lines.
US 287 runs diagonally across town. The bypass was built in 2006 and pulled through traffic off the old route, and the plan says it now serves commercial and residential growth in the southern part of the city. Methodist Midlothian Medical Center opened just off US 287 in November 2020, the first hospital in the city’s history: five stories and 200,000 square feet on a 67-acre campus, with a 45,000 square foot medical office building beside it. Clinics and specialty offices tend to cluster near a hospital, and they need medical and wellness build-outs with plumbing at every exam room.
Main Street, or Business 287, is what the plan calls the city’s primary commercial corridor. The roadway hasn’t changed much since it carried the US highway through town. Expect pad sites and strip suites with a previous tenant’s walls still standing, where a tenant improvement starts with deciding what to keep.
US 67 heads northeast toward Dallas and I-20, then bends southwest after it crosses US 287. The plan notes that several major industries use the mainline rail and the highway network. Its list of large employers includes Gerdau, Methodist, the Target distribution center, SunOpta Grains & Foods, Sunrider Manufacturing, QuikTrip Distribution, and Martin Marietta, and it points to shovel-ready land at RailPort Industrial Park, Midlothian Business Park, and Crossroads Logistics Park.
Two road projects are still on paper: SH 360 frontage roads expected to reach US 67 near Midlothian within 5 to 10 years, and a proposed Loop 9 meeting US 67 at Lake Ridge Parkway, with no funding allocated yet. Sign your lease around today’s roads.
Limestone, steel mills, and the shop buildings beside them
The cement is here because of the rock. The plan says Midlothian sits on the Austin Escarpment Chalk Ridge, a limestone reserve it puts at 600 years, and that the escarpment runs roughly north to south through the city. Quarries for the cement plants cover large tracts, and the plan’s Quarry Module keeps that land in heavy industry for the immediate future.
Heavy industry tends to draw a supporting cast of electrical, mechanical, welding, and equipment contractors who need a shop bay, a yard, and an office. That tenant often lands in a pre-engineered metal building. Steel frame, metal panels, roll-up doors, and a front office somebody has to finish.
The code work concentrates in that office: restrooms, an accessible route, exit lighting, conditioned air, the fire alarm. It’s where most of our commercial construction effort goes on a shop job, not the open bay behind it.
The 2045 plan’s criteria for industrial land show which way the City leans on a site plan. They ask for loading areas and bays at the rear of the building, screened from public view, glazing on 10 to 20 percent of publicly visible facades, patterned facade materials with articulation, and access to US 67 or US 287 frontage roads within a mile. They’re planning criteria, not zoning text, but they show the City’s direction.
Glass and office at the street, roll-up doors around the side or back. That’s the shop layout Midlothian’s plan points toward.
The Fire Marshal’s handout for developers and builders sets the order on a new site. Fire apparatus access roads and the fire protection water supply have to be in place and approved before vertical construction. Hydrants go within 400 feet of all building areas, with a minimum fire flow of 1,500 gallons per minute for two hours.
If the building is sprinklered, the list grows: a fire riser room of at least 36 square feet with direct exterior access and a heater, a Knox Box at that room, a remote free-standing fire department connection within 100 feet of a hydrant, and duct detectors on air handlers over 2,000 cfm. The same handout calls for mechanical smoke control or removal in F-1 and S-1 buildings, the factory and storage occupancies many shop buildings fall into. Price that before you sign for the building, not after.
Three generations of buildings, three kinds of projects
The original town. The City’s 2020 Downtown Plan found many downtown buildings constructed at or before 1950, some as early as the 1890s, with the most intact street walls on 7th and 8th Streets between Avenue F and Main Street. It calls the 8th Street block between Main and Avenue F the heart of downtown. The photo at the top of this page was taken at 8th Street and Railway Avenue.
The City’s 2026 Downtown Design Guidelines split downtown into six character areas. The Historic Core calls for historic architectural style. Founders Row, a newer development near the post office between 10th and 12th Streets, anchors the Downtown Business Growth area, and Old Town Residential rules out new commercial uses. The guidelines are meant to shape the City’s rewrite of its Unified Development Code, so check how far that rewrite has gone before you draw a facade.
Growth along the highways. Growth spilling over from Dallas and Fort Worth began in the mid-1970s, the Handbook says, yet Midlothian still had only 18,037 residents in 2010. Pre-2000 buildings are a thin layer.
The building boom. The plan counts an average of 391 single-family houses permitted per year since 2010 and 863 in 2023 alone, with the median sale price rising from $160,000 in 2012 to $480,000 in 2023, citing Redfin. New construction keeps moving west: the school district’s first quarter 2026 demographic report put the district’s median new home price at $491,280, with roughly 31,000 future single-family lots planned. East of town, Hanover Property Co. bought land for a 966-acre community at US 287 and Walnut Grove Road planned for 2,000 houses and 160 townhomes.
Permits, fire review, and the CO in Midlothian
Building Inspections works out of City Hall at 215 North 8th Street, downtown. Permits, inspection requests, and status checks run through the City’s MyGov portal. Online inspection requests made before 5:00 p.m. are guaranteed for the next day; phone requests take about 48 hours. Ask before the work is ready and a $50 reinspection fee may apply.
The City permits work under the 2021 international codes, from building and residential to existing building, energy, and fire, each with local amendments, plus the 2020 National Electrical Code.
The general building permit application tells you more than most city websites do:
- TDLR first. Nonresidential work valued over $50,000 needs a Texas Department of Licensing and Regulation project number on the form.
- A meeting for new buildings. The City arranges a Development Review Committee meeting with the owner and contractor for every new ground-up nonresidential project. You can decline it, but it’s an early look at every department’s concerns.
- One permit, every trade. Subcontractors register with Building Inspections before the application is reviewed, and the trades work under the building permit. Separate trade permits aren’t issued.
- Utilities vary by lot. The form asks whether water comes from the City, Sardis-Lone Elm, or Mt. Peak, whether sewer is City or private, and whether power comes from Oncor or HILCO. Know your providers before you size a meter.
A new tenant files the certificate of occupancy application, $50, for a change of owner, a change of tenant, or a new or remodeled building. It asks for seats, restrooms, and assigned parking, and whether you’ve applied for electric, gas, water, a sales tax certificate, and a City health inspection.
Then the Fire Marshal’s CO requirements, revised in August 2026, set the punch list: lighted exit signs with 90-minute battery backup, emergency lighting outside every exit door, panic hardware once the occupant load passes 49, one extinguisher per 1,500 square feet, a Knox Box at the main entrance, and an exterior main electrical disconnect or a Knox shunt trip. You also send the Fire Marshal’s office an electronic copy of the as-built floor plan.
The Fire Marshal and the building inspector both finish their CO inspections before a single chair or box of stock comes through the door.
Fire alarm and sprinkler work gets its own permit. The office takes plans by email as PDFs and sends new systems in spaces of 5,000 square feet or more, or with an occupant load of 100 or more, to an approved third-party engineer first, along with jobs moving 15 or more alarm devices or 20 or more sprinkler heads. The contractor pays the reviewer directly. The office’s inspection rules put work done without a Fire Marshal permit at risk of a $2,000 per day fine and a stop work order.
Restaurants carry the longest list. The City’s food establishment guidelines follow the Texas Food Establishment Rules: three complete sets of scaled plans go to Building Inspections, which routes them to the Building Official, the Fire Marshal, and the health side of Code Enforcement. No sealed concrete or wood floors in prep areas. Fiberglass reinforced panels or tile 8 feet up the kitchen walls. Three-inch floor drains in the kitchen, bar, and restrooms. A hand sink within 25 feet of the next one. And the grease trap goes outside, serving every sink, dishwasher, and floor drain in the prep areas.
If you’re buying an existing restaurant, the guidelines suggest calling Health and Code Enforcement before you close, since old finishes and equipment may not pass. Our restaurant construction work starts with the hood, the trap, and the drains, because the Fire Marshal’s CO list also wants a Type I hood with a UL 300 suppression system and a Class K extinguisher within 30 feet.
Remodeling Midlothian homes, from 1903 to last year
The City’s quarterly growth profile for early 2026 counted 160 permits for new houses and 58 for residential additions and remodels in three months. That’s about one remodel or addition for every three new houses.
Each starts with the City’s Residential New, Addition, or Alteration permit, and as on commercial jobs, the electrician, plumber, and HVAC contractor register first and work under that one permit. Patio covers, flatwork, accessory buildings, decks, and fences all need permits here too.
- Kitchens in the newer subdivisions. Houses in Midtowne, Redden Farms, and Villages of Walnut Grove are young enough that wiring and drains are rarely the problem. The work is layout: a real island, cabinets to the ceiling, lighting you can cook under.
- Primary bathrooms. Out goes the corner tub, in goes a walk-in shower with a bench, a longer vanity, and a quieter exhaust fan ducted outside.
- Whole-home projects on acreage. Midlothian is known for large-lot, semi-rural living, the economic development office says, and the plan’s rural module calls for 2-acre lots. On those properties, find out which water provider and sewer serve the house before you plan a new bath or a guest suite.
Old Town is its own case. The plan asks that historically residential properties keep decorative elements like wrought iron, gingerbread trim, and porches as they redevelop. If your house is a Recorded Texas Historic Landmark, state law requires written notice to the Texas Historical Commission at least 60 days before work that changes its historical or architectural integrity. The THC’s review page says it has no review authority over most interior changes and completes reviews within 30 days of receiving the documents. A new kitchen inside usually stays a city permit. New windows or a rear addition go to the THC too.
Two Old Town landmarks a few blocks apart
The William L. and Emma Hawkins House
The Hawkins name goes back to the start: the Handbook says the settlement was first called Hawkins’ Springs. William L. Hawkins, a son of pioneer settlers, and his wife, Emma, bought this lot in 1892, and the THC marker says local woodworker Will Price built the present house, finished in 1903 from imported cypress, with an asymmetrical Queen Anne design and trim he carved by hand. It’s been a Recorded Texas Historic Landmark since 1994.
The Trotter House
Jasper “Jake” Sewell Jr. bought three lots south of the business district in 1912, and the house at 508 South 9th Street likely went up after 1918. Clyde and Cloma Trotter lived there for more than 50 years. Cloma was Midlothian’s first female mayor, and she left the house to the Salvation Army. The 2017 landmark marker describes an Arts and Crafts and Prairie School blend with a large front porch, a porte-cochere, oak floors, Rookwood tiles, and a curved staircase.
How we’d run a Midlothian project from Plano
An hour’s drive changes how we schedule, not how we build. Our process opens with a site walk where we read the lease or deed and confirm the character area, the water provider, and whether the Fire Marshal will want third-party review. Then 3D renderings, before any number. The proposal is fixed in scope, organized by trade, with allowances written out.
During construction one project manager runs the job, books inspections in MyGov ahead of the 5:00 p.m. cutoff, and sends a written update with site photos each week. At handover you get as-builts, permits, inspection records, the CO, and warranties in one package, and we stay reachable after that.
Sara Bannat, our Founder and CEO, and Mahmoud Abu Saad, our COO, lead MASACO, a Goldman Sachs Preferred Vendor. Need a general contractor in Midlothian, TX, for a shop office off US 67, a suite on Main Street, or an Old Town house with good bones? Book a consultation and bring the site plan or a few photos. You’ll leave with a design to look at and a proposal to hold us to.
Building in Midlothian: what to know.
Midlothian had 7,480 residents in 2000 and 46,683 by July 2025, so most of its houses and shopping centers are recent, while cement plants, limestone quarries, and the Gerdau steel mill still anchor its industrial economy. The original town around North 8th Street keeps brick storefronts from as early as the 1890s and now has its own 2026 design guidelines. Building Inspections at City Hall, 215 North 8th Street, permits work under the 2021 international codes and the 2020 National Electrical Code, and the Fire Marshal inspects every new tenant before a certificate of occupancy.
