SBA size standard

We hold no size standard published for these exact six digits, and we will not put a neighbouring industry's figure here in its place. Sibling codes in the same NAICS family do not always share a standard, and self-certifying against the wrong one is how a bidder ends up claiming a set-aside they do not qualify for. Look 238220 up directly in the SBA table.

An exact count of the federal contract award records we hold carrying NAICS 238220. It is more than this page folds in one pass (500awards), so we publish no dollar totals or contractor rankings for this code — a ranking computed from part of an industry is not that industry's ranking. The state breakdown below is measured separately and each row is exact for its state.

Where NAICS 238220 work is performed

Award records under 238220 in the 47 stateswhere this industry ranks among that state's largest by contract dollars. Each row is exact for its state; a state where 238220 ranks below that cut contributes nothing here, so treat the list as a floor rather than a national breakdown. Measured August 21, 2026 — these figures describe the records we held at that moment.

How to use a NAICS code to win government work

Your NAICS code is not paperwork trivia. It is the hinge the whole federal eligibility question turns on: the buyer assigns one code to the requirement, that code sets the SBA size standard the offers are measured against, and the size standard decides whether your business counts as small — and therefore whether you can compete for the set-aside version of the work at all.

Which means the first question is never “can I do this job”. It is “is this contract classified as work I am registered and sized to do”. A firm that can genuinely perform under 238220 but never listed it on its SAM.gov registration is invisible to the market research a contracting officer does before writing the solicitation, which is where most small-business awards are really decided.

Award history under a code tells you the rest. It shows which agencies actually buy this work and where, which contractors have been holding it, and roughly what it pays — before you spend two weeks on a proposal against an incumbent who has held the contract for nine years. A contract with an end date twelve to eighteen months out is a recompete in the making, and the quiet window before it is posted is when a capability statement and a call to the contracting office are worth more than any proposal you could write later.

None of it works if you are not registered. A federal award requires an active SAM.gov registration with a UEI, and the set-aside on a solicitation decides whether your bid is even read. Both are free to sort out, and both are the most common reason a ready contractor is disqualified on a technicality.

Where this page's facts come from

  • The classification. U.S. Census Bureau 2022 NAICS. Codes, titles and the sector hierarchy are reproduced verbatim from the Census files and cross-checked against a second official Census file. Nothing is paraphrased or shortened.
  • The size standard. SBA, 13 CFR 121.201. We print a threshold only when it is published for these exact six digits; where it is not, we say so and link the table rather than showing a related industry's figure.
  • The award figures. Federal prime contract awards published by USAspending.gov, the government's official spending record. Public record, free, no data vendor in between. Grants, loans and direct payments are excluded — they are not work a contractor competes for — and so is state, county and city purchasing.
  • What is not here. This is a portion of federal contracting under 238220, not all of it. Treat these figures as a floor: the real market is larger than what is on this page. For an industry this size we publish the exact record count and the per-state figures, and deliberately publish no dollar totals or rankings, because the fold a page render can afford would cover only part of the code.
  • Missing values. Where USAspending records no amount, agency or recipient, we leave it out instead of filling it in. An award with no reported amount is still counted as an award but enters no total or average, which is why a row's award count can outrun its dollars.

NAICS 238220 — common questions

What is NAICS code 238220?
238220 is the U.S. Census Bureau's 2022 NAICS code for Plumbing, Heating, and Air-Conditioning Contractors, inside the Construction sector and the Specialty Trade Contractors subsector. Federal solicitations carry exactly one NAICS code, and that code is how the buyer classifies the requirement — it decides which size standard applies to the bid and, with it, whether your business counts as small for that contract.
What is the SBA size standard for NAICS 238220?
We do not hold a size standard published for these exact six digits, and we will not show you a neighbouring industry's figure in its place — sibling codes in the same NAICS family do not always share a standard, and self-certifying against the wrong one is how a bidder ends up claiming a set-aside they do not qualify for. Look up 238220 directly in 13 CFR 121.201, which lists a threshold for every code.
Where is NAICS 238220 work performed?
California leads of the states whose award records we hold for this code, with 3,045 awards. Place of performance is where the work happens, not where the winner is headquartered, so this is the market you would be serving rather than a list of local companies. Every state whose stored industry leaderboard reaches this code is listed on this page, each linking to its own award history; a state where it ranks below that cut is missing from the list entirely.
Are there open government bids under NAICS 238220 right now?
Yes — 10 open solicitations carry this code as of this page load. The 6 closing soonest are listed above, with the buyer, the deadline and the agency's own published record. Solicitations come and go daily, so the free alert list is the reliable way to hear about the next one while there is still time to bid.
Do I have to use NAICS 238220 to bid?
You bid what the solicitation says. The buyer assigns one NAICS code to the requirement, and that code — not the list on your SAM.gov registration — sets the size standard your offer is judged against. Your registration should carry every code you can genuinely perform, because that is what buyers filter on during market research, but adding a code you cannot deliver under does not make you eligible for anything.
