BLS QCEW, 2026Q1The figures above are County Business Patterns, which carries the size distribution but runs about two years behind. The Bureau of Labor Statistics publishes quarterly, so this is the same industry roughly 3 years later. The two count different universes, Census counts establishments with paid employees in the March pay period and BLS counts worksites covered by unemployment insurance during the quarter, so the numbers are not directly comparable and either can be the larger.

How this market compares
Napa County against every other county in California on the same measure. The median excludes places under 2,000 residents, where per-capita figures are arithmetically true but analytically useless.
Well above the state median for this industry. A crowded market: expect established competitors and price pressure, but also a deeper pool of businesses to buy.

Density compares architectural services provision per resident. It does not measure revenue, profitability or whether a market is worth entering.
Business size mix
Napa is more fragmented than California as a whole: a larger share of very small operators. Fragmented markets are where roll-ups are assembled, and where an owner nearing retirement has no obvious internal buyer.
| Share of establishments | Napa | California | Difference |
|---|---|---|---|
| Under 5 employeesOwner-operated, often no management layer | 82.4% | 66.2% | +16.2% |
| 5 to 49 employeesThe range most individual buyers target | 17.6% | 30.2% | -12.6% |

What acquirers look at
Reputation and principal relationships rarely survive an owner exit. Firms with public-sector master service agreements are the exception worth pursuing.
