NAICS 561790: Other services to buildings and dwellings federal contracts, size limit and who buys
Federal spending, new contracts, buying agencies and set-asides for NAICS 561790 (other services to buildings and dwellings), from USAspending.gov, with the SBA size limit and what the code covers.
Pressure washing and exterior cleaning, duct and kitchen exhaust hood cleaning, gutter and drain cleaning, parking lot sweeping, chimney cleaning, pool cleaning, light bulb replacement, and snow plowing on its own. Window cleaning is janitorial (561720). Sandblasting a building is a specialty trade (238990).
| Small business size limit | $9.0 million average annual revenue |
|---|---|
| Federal spending, FY2026 | $59 million |
| New contracts and orders, FY2026 | 387 |
| Typical new standalone contract | $73,000 (middle half $42,000 to $132,000) |
| Set aside for small businesses | 57% of new standalone contracts |
| Women-owned set-asides | EDWOSB only |
It's a small code with a low size limit, which keeps the competition small. Snow removal is its biggest use: in our Mid-Atlantic count, more than half of snow contracts used it.

Common questions
What kind of work uses this code?
Building services that aren't cleaning the inside, landscaping, pest control or carpet cleaning: pressure washing, duct and hood cleaning, gutters, parking lots, pools and snow plowing.
Why does the size limit matter so much here?
At $9.0 million it's one of the lowest in facilities work. A firm that's small for janitorial ($22.0 million) can be too big to count as small here.

Agencies don't always code the same work the same way, so it pays to list several codes. Our guide to which NAICS codes to list explains why.
