What's the NAICS and SIC code for a property developer?
For a property developer, use NAICS 236117 (New Housing For-Sale Builders) in the US and SIC 41100 (Development of building projects) in the UK.
United States, NAICS 2022

When a different code fits better
These are the codes most often confused with the main answer. Pick by the activity that earns most of your revenue.
| Code | Title | Use it if |
|---|---|---|
| NAICS 236116 | New Multifamily Housing Construction (except For-Sale Builders) | you build multifamily housing for clients rather than for your own sale |
| NAICS 531110 | Lessors of Residential Buildings and Dwellings | you keep the homes and rent them out |
| SIC 68100 | Buying and selling of own real estate | you buy and sell property without developing or building it |
| SIC 41202 | Construction of domestic buildings | you do the construction work on homes yourself as a builder |
Good to know
A developer who buys, renovates and sells (flipping) usually fits 68100 in the UK. In the US, choose based on whether you run the construction.
You can list more than one code. Companies House accepts up to four SIC codes, and SAM.gov lets you add several NAICS codes, with one marked as primary.
What the code affects
- SBA programs and federal contracts: your NAICS code sets the size limit you must stay under to count as small. Check your size.
- SAM.gov registration: contracting officers search by NAICS, so list every code you can deliver work under.
- Companies House: your SIC code appears on the public register and in your confirmation statement.
