01
For most nonprofits, it covers the whole organization
When a private organization's main work is education, health care, housing, social services, or parks and recreation, or when federal money goes to the organization as a whole, Section 504 covers all of its operations, not only the funded program. A Head Start grant brings in the gym, the website and the event registration too. Other private organizations are covered at the facility the money reaches.
29 U.S.C. 794(b)(3)
02
Money passed through someone else still counts
A recipient is any organization federal assistance reaches directly or through another recipient. Federal money that arrives through New York State, a city agency or another nonprofit makes you a recipient. A city contract can be paid with federal dollars without saying so on its face.
45 CFR 84.10, “Recipient”
03
Not every federal dollar counts
Grants, subgrants, cooperative agreements and loans count, and so does money passed through a state or city. A direct federal procurement contract doesn't, and neither does a contract of insurance or guaranty. Organizations that sell to the federal government answer to Section 503 instead, which is an employment obligation.

04
The agency that funds you sets the terms
Each federal agency writes its own Section 504 rule. HHS, the Education Department and HUD each require a designated coordinator and a grievance procedure at fifteen employees. The Justice Department's rule sets the line at fifty employees and $25,000 in Department funding. An organization with several funders answers to each rule, and one coordinator can hold all of them.
