Does the ADA cluster rule apply to a private wedding on private land?

The ADA cluster rule does apply to a private wedding on private land if you are inviting the public or if it is a place of public accommodation. The 2010 ADA Standards for Accessible Design require that where multiple single-user portable toilets are clustered at a single location, at least 5 percent of the units in each cluster must be ADA-compliant portable toilet. For a cluster of four units, this means at least one accessible unit is required. The rule applies to events open to the public, such as weddings where guests are not exclusively personal friends and family in a purely private residence context. If your wedding is considered a public event, you must comply.

Key factors for the rental company's advice: Rental companies often err on the side of compliance to avoid liability and because local permit offices or health departments may require it for any event with a certain size. Even on private land, if you have a large gathering, authorities might classify it as a public assembly.

What an ADA-compliant unit provides: An ADA-compliant portable toilet includes a wider door, internal turning space, grab bars, and an accessible height toilet seat. It ensures guests with mobility devices can use the facilities.

When it might not be strictly required: If your wedding is truly private, with only invited guests and no public advertising, and it is held at a personal residence not used for commercial events, the ADA may not mandate an accessible unit. However, many rental companies include it as a best practice to accommodate all guests and avoid potential issues.

For four units, adding one accessible unit is a reasonable approach. Check with your local permit office or the rental company about specific requirements for your area. Does anyone have experience with similar situations?
