What a request is, under the rules
Title III covers private businesses and nonprofits that operate places of public accommodation. A program that receives federal financial assistance carries Section 504 as well, and a public entity's program answers to Title II, so both citations are shown.
A request to change how it's done
Most requests ask a program to change a policy, practice or procedure: a different start, an extra break, a companion, a guide, another way through the venue. The change has to be made when it's needed, unless it would fundamentally alter what the program offers.
28 CFR 36.302(a) and 35.130(b)(7)
Eligibility rules have to be necessary
Age bands, qualifying times, health questions and equipment rules can screen people out. They stand only when they're necessary to provide what's offered, and a safety rule has to rest on actual risks, not speculation, stereotypes or generalizations about people with disabilities.
28 CFR 36.301(a) and (b); 35.130(b)(8)
No surcharge for it
The cost of an interpreter, a modified setup or a changed policy can't be charged to the person who needed it, or to people with disabilities as a group.
28 CFR 36.301(c) and 35.130(f)
Communication that works
Registration pages, confirmations, safety briefings and announcements on the day have to reach people who are deaf, hard of hearing, blind or have low vision. The program chooses the method, asking the person where it can, and the method has to work, arrive in time and protect the person's privacy and independence.
28 CFR 36.303(c)
Service animals and mobility devices
Staff may ask two questions about a service animal and may not demand documentation. Wheelchairs and manually powered aids go wherever people on foot can go, and other power-driven mobility devices are allowed unless the program can show that type of device can't be operated within its legitimate safety requirements.
28 CFR 36.302(c)(6) and 36.311
Ask the person what works
For communication aids, a Title III program should ask the person what will work whenever it can, and the choice is the program's as long as the method works. A public entity gives primary consideration to the person's request.
28 CFR 36.303(c)(1)(ii) and 35.160(b)(2)
