Every space in the lot being counted, accessible ones included — but see the note for hospital and rehabilitation facilities, where the denominator is not the whole site.
The table scopes against what is provided, not against what a zoning ordinance demanded, so a lot that over-provides scopes higher. Count the accessible spaces themselves within the total — they are parking spaces, and excluding them understates the requirement. The hospital and rehabilitation rows are the exception to "every space": those higher ratios (10% and 20%) apply to the PATIENT AND VISITOR parking only, so enter just those spaces when either facility type is selected and run the employee and general lots separately at the standard table. Entering the whole site against a 20% ratio scopes an outpatient facility several times over.
How many distinct parking facilities the site is divided into.
Scoping runs per facility rather than across a site, and that matters because the table is not linear: two lots of 240 need more accessible spaces between them than one lot of 480. This page splits the total as evenly as it can; where the lots differ in size, run each one on its own and add the answers.
Which scoping rule the facility this parking serves falls under.
Two categories replace the table with a straight percentage of the patient and visitor spaces, because the population using them is far more likely to need an accessible space. The rehabilitation figure applies where the facility specialises in conditions affecting mobility; employee and general spaces at the same site are still scoped from the table.
Accessible spaces required
7 spaces
This is the federal minimum. State and local accessibility codes are frequently stricter, and where they are, theirs is the number to build to.
- Of those, van-accessible
- 2 spaces
- Remaining car-accessible
- 5 spaces
- Spaces per parking facility
- 250 spaces

How this was calculated
Formula source(s)
- ADA Standards for Accessible Design, Section 208.2 — the scoping table relating total spaces provided in a parking facility to the minimum number complying with Section 502, including the two percent rule from 501 to 1,000 spaces and the twenty-plus-one-per-hundred rule above that
- ADA Standards for Accessible Design, Section 208.2.4 — at least one van-accessible space for every six, or fraction of six, accessible spaces required
- ADA Standards for Accessible Design, Sections 208.2.1 and 208.2.2 — ten percent of patient and visitor spaces at hospital outpatient facilities, and twenty percent at rehabilitation and outpatient physical therapy facilities
- Scoping is applied per parking facility, not to a site total. State and local accessibility codes may require more, and where they do they govern.
Inputs used
- Total Parking Spaces Provided
- 250
- Number of Separate Parking Facilities
- 1
- Facility Type
- General — scoped from the 208.2 table
Intermediate steps
- Of those, van-accessible
- 2 spaces
- Remaining car-accessible
- 5 spaces
- Spaces per parking facility
- 250 spaces
Confidence note: This is the federal minimum. State and local accessibility codes are frequently stricter, and where they are, theirs is the number to build to.
What this calculation does not cover
- Stall and access aisle dimensions, vertical clearance on the van route, surface slope and the accessible route to the entrance are separate requirements and are not checked here.
- Placement is not a leftover decision: accessible spaces belong on the shortest accessible route to the entrance they serve.
- Residential, employee-only and valet arrangements are scoped under their own provisions rather than by this table.
