The going rate for 5-day office cleaning in downtown Houston has compressed by roughly 8–9% since 2023, and a new bidder walking the building without a firm sense of the labor floor will underprice so deep the account is lost in year two. Houston’s Energy Corridor west of the 610 Loop generates massive Class B square footage tied to the oil-and-gas sector’s boom-and-bust cycle. Multi-year Energy Corridor bids need a vacancy clause or a rate that holds margin under partial-occupancy conditions.

Houston Labor Cost Inputs

BLS OEWS May 2024 (SOC 37-2011) puts the Houston-The Woodlands-Sugar Land MSA in the $14–$16/hr range, median near $13.50. Texas follows the federal minimum of $7.25/hr with no state or city floor above federal. The Woodlands and Sugar Land campuses often pay $0.50–$1.00/hr above the Houston city mean to attract workers commuting from Harris County.

Burden math on a $15/hr Houston base: FICA 7.65% = $1.15; FUTA/SUTA ~2% = $0.30; occupational accident insurance (non-subscriber) approximately $2.00–$2.60 per $100 payroll per the Texas Department of Insurance; health insurance ~$3/hr; vacation ~4%. Total burden: 27–31%, loaded rate near $19–$21/hr. See the wages breakdown for the Houston MSA.

Sample Scope of Work: Class B Office Building

Hypothetical 40,000 sq ft Class B building in the Galleria area or Energy Corridor. Houston humidity and year-round AC create mold watch requirements in restrooms during June–September.

Houston Market Rates: Class B Office and Day Porter

Galleria, Greenway Plaza, and downtown Houston Class B commands $0.09–$0.14/sq ft/month for 5x/week. The Woodlands and Sugar Land corridors: $0.08–$0.12. Single-story suburban strip-center office: $0.07–$0.10. Day-porter bill rate: $20/hr x 2.3 = approximately $46/hr; 5-hr/day porter near $1,150/month. Use the day-porter ROI calculator before discounting. Texas Medical Center medical office adds +25–35%; post-construction +40–55%.

Houston Licensing and Insurance Requirements

No state janitorial license required. The City of Houston requires a general business license. Texas sales tax applies to some cleaning services; review the Texas Comptroller sales tax FAQ for contract classification. Texas Medical Center contracts require $2M/$5M GL; Class B standard is $1M/$2M. Occupational accident insurance at approximately $2.00–$2.60 per $100 payroll per the Texas Department of Insurance. TX state contracts use the HUB program.

Union Landscape and Prevailing Wage

Houston is a Right-to-Work state with minimal SEIU presence in commercial cleaning. Federal buildings (Ellington Field JRB, VA Medical Center Houston) fall under the Service Contract Act; pull the applicable wage determination from SAM.gov. Full SCA guidance: dol.gov/agencies/whd/government-contracts/sca. No city-level living wage ordinance applies in Houston as of 2026.

Bid Line-Item Structure for Houston Buyers

1. Monthly base service: hours x loaded rate by shift (evening, day porter, supervisor).
2. Weather and humidity supplement: summer mold-watch or tropical storm response, quoted separately.
3. Supplies schedule: consumable unit pricing; required on TX state RFPs.
4. Equipment depreciation: 36–48 months; tile grout brushes add replacement cost.
5. Insurance and overhead: GL, occupational accident, bond, and 12–17% indirect costs pro-rated to account.
6. Profit margin: 8–13% on competitive commercial accounts. Pass-throughs quoted separately.

Local quirk: Texas Medical Center contracts require detailed infection-control addenda specifying product names, EPA registration numbers, and dwell time protocols. A generic scope sheet will not clear TMC procurement review.

Bid Walk Checklist: Houston MSA

1. Inspect mechanical rooms and under-sink cabinets for condensation or mold; Houston humidity creates these faster than dry-climate markets.
2. Check restroom exhaust fan condition; failed fans drive mold complaints attributed to the BSC.
3. Confirm pest control responsibility in the contract; confusion over roach or ant response generates disputes.
4. Verify HVAC diffuser inspection schedule; year-round AC creates more duct-dust accumulation than seasonal systems.
5. Ask about prior water intrusion or flooding; post-Harvey moisture issues persist in some Harris County buildings.

The Vacancy Risk in the Energy Corridor

Accounts in Houston’s Energy Corridor carry occupancy risk that Class B accounts elsewhere do not. A 5-year contract at $0.12/sq ft on a 60,000 sq ft building becomes below-cost if 20,000 sq ft goes dark and the remaining 40,000 sq ft still requires daily empty-floor sweeping at the same labor allocation. Build a vacancy clause into any multi-year Energy Corridor contract, or price the full footprint at a rate that holds margin under partial-vacancy. Buyers who resist that clause are asking you to absorb their tenant-retention risk for free.
