If you have only ever done residential, commercial can look like the same work at a bigger size. In practice the scale, the timeline, the building systems, the money, and the rules all change at once. The table below shows what is different, so you walk in knowing what you are stepping into.

At a glance

Notes on the table above:

• Scale and footprint: Both ranges are RocketLevel working figures from the jobs we run, so check them against your own last hundred jobs before you plan against them
• Regulatory load, Residential: EPA's Renovation, Repair and Painting (RRP) rule (40 CFR 745 Subpart E) covers pre-1978 target housing and child-occupied facilities, and requires a certified firm and lead-safe work practices
• Regulatory load, Commercial: RRP is narrower here, not absent. It still reaches pre-1978 child-occupied facilities; the detail is in the toggle below this table
• Regulatory load: where RRP still reaches commercial work

What changes the most

<aside> ⚖️

Reviewed October 2026. Safety, environmental and wage rules change, and they vary by state. Use this page to know what to ask, then confirm with your state agency or a construction attorney before you rely on it.

</aside>

• Uptime is what you are selling. On a hotel or a hospital, every hour of downtime is lost revenue, and drying is only part of how you keep the business open (see The Uptime Sale: What Commercial Decision Makers Are Actually Buying).
• The decision maker is a professional. Property managers and risk managers buy on documentation, response time, and standard of care. A friendly estimate won't carry the day.
• The rules multiply, and they are not the residential rules scaled up.
  • Safety. OSHA construction standards on every site.
  • Asbestos. An asbestos inspection before any demolition or renovation, with no square-footage floor and no building-age cutoff on the inspection itself (40 CFR 61.145(a)). The quantity thresholds sitting in that same paragraph, 260 linear feet on pipes, 160 square feet on other facility components, or 35 cubic feet, do not decide whether you look. They decide which notification and work-practice duties attach once you have looked, which is a different question and the one people get backwards.
  • Presumed asbestos. OSHA separately presumes asbestos in thermal system insulation and surfacing material in buildings constructed no later than 1980 (29 CFR 1926.1101(b)), a presumption the employer or building owner rebuts by demonstrating the material does not contain asbestos (1926.1101(k)(5)), not a date below which you can skip looking. Asphalt and vinyl flooring installed no later than 1980 gets the same treatment (1926.1101(k)(1)(i)).
  • Lead. Lead work on general commercial space is governed by OSHA 1926.62 rather than the RRP certification your residential crews carry, because EPA never proposed a public and commercial buildings rule, let alone finalized one.
  • The RRP exception. Know the exception before you bid a school, a church, or a medical office with a daycare wing. A pre-1978 child-occupied facility stays inside RRP even when it sits within a commercial or public building, and 40 CFR 745.83 says so in as many words. Scope that covered footprint on paper before you mobilize, because the certified firm and certified renovator requirements attach to it and not to the hallway outside it. The full split is in Lead-Safe Work on Commercial Buildings: OSHA 1926.62, Not EPA RRP.
  • Mold. Third-party clearance on healthcare mold. Whether one firm may both assess and remediate a mold loss is set by state law and differs by state, so read your own state's mold licensing statute before you quote both halves of that scope.
  • Code upgrades on major rebuilds.
  • Prevailing wage on public work, which on federal contracts means Davis-Bacon on every contract in excess of $2,000 for construction, alteration, or repair (40 U.S.C. 3142(a)), a threshold low enough that essentially any job you would want clears it. State and locally funded work runs on whatever prevailing-wage law that state has, which is a question for the state rather than a number we will quote you.
• The money is structured. Progress billing, master service agreements, time and material, and a commercial property claim that often runs alongside a business income claim replace the single homeowners check.
• Read the room either way. The emotional temperature tends to run lower on commercial work, but it isn't absent. A business owner facing lost revenue, displaced tenants, or a closed storefront can be just as charged as a homeowner. There's also a day-to-day difference for your crews, since residential often means working in an occupied home around the family, while commercial is more often a vacated or after-hours facility.

Why the shift is worth learning

Every difference above is learnable, and the Hub covers each one. Contractors who show up knowing the timeline, the systems, the rules, and the money are the ones property managers keep calling.

The residential base is also getting less dependable: in a ValuePenguin survey of 1,999 US consumers fielded 20 to 21 February 2025, 25% of homeowners said they had received a nonrenewal notice from their insurer, with coverage hardest to find in states like California, Texas, and Florida. That figure is self-reported, and the survey asked about nonrenewal notices received rather than about drops that occurred during 2025. ValuePenguin puts the prior wave of the same survey at 19%. The figure also runs far above the nonrenewal rates state regulators publish, so treat it as consumer sentiment rather than carrier data. Directionally it is one more reason a commercial channel is worth building.
