Other codes worth listing
- 531312 Nonresidential Property Managers ($19.5 million): if you manage commercial property for its owners rather than doing the work.
- 531311 Residential Property Managers ($12.5 million): the same for residential property.
Agencies don't always code the same work the same way, so listing every code that fits gets more bids in front of you. Our guide to which NAICS codes to list explains how.
