Every commercial parking lot in Connecticut needs to meet the Americans with Disabilities Act (ADA) accessibility requirements, and most municipalities also enforce state-level standards on top of the federal baseline. Getting striping right matters for compliance, liability, and visitor experience. This guide summarizes the requirements as they typically apply to a CT commercial property.
A commercial parking lot in Connecticut needs at least one accessible space for every 25 total spaces, with van-accessible spaces required at a 1-in-6 ratio of accessible spaces. Accessible spaces must be at least 8 feet wide with a 5-foot access aisle (96 inches wide for van-accessible). Signage with the international accessibility symbol is required at every accessible space.
Federal ADA requirements set the minimum number of accessible spaces based on total lot size. The scale runs: 1 accessible space for lots of 1-25 total, 2 for 26-50, 3 for 51-75, 4 for 76-100, and progressively more for larger lots. Connecticut municipalities sometimes enforce stricter local requirements on top.
Within the accessible spaces, at least 1 in every 6 must be van-accessible. For lots with fewer than 6 accessible spaces total, at least one of them must be van-accessible.
Standard accessible space: 8 feet wide minimum with a 5-foot access aisle alongside. Two accessible spaces may share a single access aisle between them.
Van-accessible space: 8 feet wide minimum with a 96-inch (8-foot) access aisle, OR 11 feet wide with a 5-foot access aisle. The wider aisle accommodates a wheelchair lift or ramp deployed from the van.
The access aisle must be marked clearly (typically with diagonal hatching) so it cannot be parked in. The aisle floor must be level — slope under 1:48 in all directions — and at the same level as the parking space.
Accessible spaces must be on the shortest accessible route to the building entrance they serve. When multiple entrances exist, accessible spaces are typically distributed across them.
The accessible route from space to entrance must be at least 36 inches wide, with running slope no greater than 1:20 and cross slope no greater than 1:48. Where the route crosses curbs or steps, curb ramps must comply with ADA dimensions.
Each accessible space requires a vertical sign with the international symbol of accessibility, mounted at least 60 inches above grade so vehicles parked in the space do not obscure the sign. Van-accessible spaces require an additional "Van Accessible" designation on the sign.
Pavement markings: the symbol of accessibility painted on the space itself is required in Connecticut. Diagonal hatching on the access aisle is required to deter parking in it.
In CT lots we re-stripe, the most common gaps are: insufficient access aisle width (a 5-foot aisle that has been resurfaced and lost width over time), missing or fading van-accessible signage, parking aisle slope exceeding 1:48 from settling, and access aisles that are parked in routinely. Re-striping the lot to current ADA dimensions corrects most of these.
If a lot is being repaved, that is the right time to verify or correct the ADA layout. We confirm dimensions, plan signage placement, and stripe to current standards as part of the project.
Federal ADA Standards have been substantively stable since the 2010 update. Connecticut state requirements and local enforcement vary. We stripe to current federal + CT requirements as of the project date.
No — the required minimum count is set by total space count and cannot be reduced. If a re-striping plan would reduce total spaces enough to drop the accessible requirement, the accessible count is still required at the new total.
Yes — if the lot has any accessible spaces at all, at least one of them must be van-accessible. A lot with just 1 accessible space means that 1 space is van-accessible.
If accessible spaces are faded, signage is missing, or dimensions have drifted from re-paving over the years, yes — correct them before inspection. We re-stripe and re-sign as needed.
A commercial parking lot is a significant investment and a working part of your business. Understanding how the paving process unfolds helps you plan, budget, and keep operations running.
