Construction companies in Houston: the market, the permits and how to vet a contractor

This report is for property owners and developers choosing a contractor in the Houston area, people researching the local construction market, and B2B sellers whose customers are builders and trade contractors: suppliers, equipment rental, insurance, staffing and software.

Houston construction by the numbers

County Business Patterns 2023 covers construction (NAICS 23) in the Houston-Pasadena-The Woodlands, TX Metro Area (CBSA 26420).

The heavy and civil numbers are what set Houston apart. Its 996 firms average 60 employees each, against about 10 for building contractors, which fits the large crews that pipeline, plant and utility work needs.

Size and location

In broader bands: 10,272 establishments have 1 to 19 employees, 1,364 have 20 to 99 and 386 have 100 or more. Houston has 22 construction sites or offices with 1,000 or more employees.

Brazoria County averages 24.7 employees per establishment, close to Harris County's 21.5, while the suburban counties of Montgomery and Fort Bend average 11 to 13.

Limits of the count. These are establishments with paid employees, not companies; a contractor with a yard in Pasadena and an office in the Galleria counts twice. Sole proprietors with no employees are excluded. Head offices can be classified outside construction, and employment is a single week in March 2023. The Greater Houston Partnership, using Texas Workforce Commission data, reports 257,620 construction jobs and 12,618 establishments in 2025; it's a different source and year, so don't mix the two in one calculation.

Finding Houston contractors and projects

The City of Houston states plainly that it does not have zoning. Land use isn't mapped years ahead, so the signals of new work are permits, plats and the developers behind them:

• Building permits. City of Houston permits totaled $9.0 billion in 2025: $3.2 billion residential, $1.4 billion commercial and $4.4 billion additions and alterations (Greater Houston Partnership, Houston Facts 2026). The city points to the Houston Permitting Center's sold permits search for current permits.
• Residential permit applications. The city's open data shows 4,785 single-family and 7,248 multi-family permits applied for in 2025.
• Plats. The Planning and Development Department publishes a Plat Activity Report for each Planning Commission meeting, every other Thursday, with location and applicant details: a list of subdivisions and sites before ground is broken.
• Unincorporated Harris County. Outside city limits, the Harris County Office of the County Engineer issues permits and runs a permit search.

How to vet a Houston contractor

1. Check trade licenses. TDLR's license search covers air conditioning contractors, electricians, elevator contractors and more; plumbers are licensed by the Texas State Board of Plumbing Examiners. General contractor isn't among TDLR's license types, so a GC's own license number proves little.
2. Look up its permit history in the city or county permit search: how many jobs like yours, how recent, and whether they passed inspection.
3. Get certificates of insurance and bonding capacity in writing, and confirm them with the issuer.
4. Ask for three references on similar projects in the last two years, and visit one.
5. Compare bids line by line, with the same scope, and agree how changes and payment draws will work before you sign.

Selling to Houston construction companies

Heavy and industrial contractors buy differently from homebuilders: safety prequalification, equipment and crane rental, crew transport and staffing matter more than design tools. Specialty trades (the largest group) buy tools, vans, parts and scheduling software in small, frequent purchases.

Illustrative example. The seller and its rates are invented; the counts are Census 2023 data.

Bayou Lift Rentals (bayoulift.example) rents aerial lifts and telehandlers. Its target is nonresidential builders and the largest specialty trades in Harris and Brazoria counties. Metro-wide there are 1,017 nonresidential building establishments; it estimates 70% are in those two counties, about 712. Adding the 386 establishments of any type with 100 or more employees, and allowing for overlap, gives roughly 950 accounts. If 10% rent a lift for an average of six weeks a year at $1,900 a week, that's 95 customers and $1,083,000 in annual rental revenue. The research that matters is which of those 950 have permits filed now. Bebop finds contractors that match a description and builds a playbook for each one.

Subject: Lifts for [project name or address]

Hi [first name],

I saw [company] pulled a permit for [project, e.g. a 3-story medical office in Katy] this month.

On jobs that size the lift schedule usually slips when the steel does. We keep a reserve fleet in [area] and swap units within a day, so your trades don't stand around.

Worth a 10-minute call on [day] to line up equipment before you mobilize?

[Your name]
