Van Accessible Parking Spaces St. Louis
ADA Table 208.2 ratio requirements, §502.2 dimensional standards, ISA symbol specs, and the most-cited violations at St. Louis commercial, healthcare, and institutional properties. Correct striping prevents $75,000+ first-offense fines.
ADA First-Offense Fines: Up to $75,000. Van accessible space violations are among the top 3 most-cited ADA parking deficiencies in Missouri DOJ compliance reviews.
The 1:6 Van Accessible Ratio Rule
Per ADA Table 208.2, at least 1 of every 6 accessible parking spaces must be van accessible. The rule applies to every parking facility — commercial lots in Clayton's office district, medical campuses near Barnes-Jewish Hospital on Kingshighway, and cultural institution lots at Forest Park.
Missouri Botanical Garden, the Saint Louis Art Museum, and the Saint Louis Science Center all manage high-volume accessible parking in Forest Park — and each is subject to the same 1:6 ratio under the 2010 ADA Standards for Accessible Design.
Quick Answer
For a 100-space lot in St. Louis: ADA requires 4 accessible spaces minimum. Of those 4, at least 1 must be van accessible. Most property owners in Chesterfield and Richmond Heights fail by having the right number of accessible spaces but no van accessible designation.

Exact Van Accessible Space Dimensions
Two compliant configurations exist — most St. Louis properties use the 11-foot stall layout
11-Foot Stall with 8-Foot Access Aisle
Standard for most commercial lots, hospital parking structures, and strip centers across Clayton Road and Manchester Road corridors
9-Foot Stall with 8-Foot Access Aisle
Only valid if the stall is explicitly designated van accessible on signage and pavement markings
Required Signage: ADA §502.6
ISA Symbol Sign
Standard International Symbol of Accessibility (blue/white R7-8 sign). Required at every accessible space — van accessible or standard. Minimum 60 inches from grade to bottom of sign.
"Van Accessible" Supplemental Sign
A secondary sign reading "Van Accessible" must be mounted directly below the ISA sign. This is a separate sign, not just text on the main sign. Most violations in Chesterfield hospital lots involve this sign missing entirely.
ISA Pavement Symbol
Per ADA §502.6, the ISA symbol must also be painted on the pavement surface: minimum 36×36 inches, centered in the stall, contrasting blue and white. Richmond Heights mall lots and older Clayton office lots frequently have symbols that are too small or have faded past legibility.
Common Violations at St. Louis Properties
DOJ compliance reviews and private ADA lawsuits in the St. Louis metro have identified these as the most frequently cited deficiencies at commercial, institutional, and healthcare properties:
Wrong Access Aisle Width
Standard accessible spaces have 5-foot aisles. Van accessible spaces require 8-foot aisles. Many lots in Chesterfield Valley and Clayton were built with uniform 5-foot aisles across all accessible spaces — a violation for any stall designated as van accessible.
Missing Van Accessible Supplemental Sign
Having the ISA sign is not enough. The separate 'Van Accessible' sign below it is mandatory and is missing from the majority of St. Louis commercial lots we inspect.
ISA Symbol Too Small or Faded
Pavement ISA symbols must be 36×36 inches minimum. Symbols painted at 24×24 inches — common at older Forest Park area cultural institution lots — are non-compliant.
Access Aisle Blocked by Landscaping
Shrub overgrowth from adjacent landscape islands blocking access aisles is a recurring issue at medical office parks near the Barnes-Jewish Hospital complex on Kingshighway Boulevard.
