Simple event math from our McKinney crew.

The formula

Guests × hours ÷ 250

Multiply guests by hours, then divide by 250. Round up. Never go below 1 unit.

Alcohol

Serving drinks?

Add 1 unit for every 4 you planned, with a minimum of 1 extra.

Food

Serving food?

Add 1 hand wash station for every 4 units, minimum 1.

5%

Wheelchair access

Make at least 5% of each cluster wheelchair-accessible, minimum 1 when 2 or more units are grouped.

2010 ADA Standards §213.2

Example

150 guests, 5 hours

150 × 5 = 750. Then 750 ÷ 250 = 3 units.

4

Add the bar

A bar adds 1 unit, so you need 4. Make 1 of the 4 wheelchair-accessible.

Double-check

Confirm with your venue

Check counts with your venue, HOA or permit office. We will go over the numbers when you call.
