Compliance with the Americans with Disabilities Act (ADA) at your parking lot isn’t optional, and it isn’t just about avoiding enforcement actions. It’s about making your property usable by everyone who needs to use it. It’s also about not waking up to a demand letter from a plaintiff’s attorney who has photographed your faded striping, your missing van-accessible signage, and the 4% cross slope on your accessible route. Every year, we run into at least a dozen properties along the Front Range that are either being sued or actively targeted for ADA violations they didn’t know they had.
Concrete & Asphalt 4 Colorado evaluates, corrects, and installs ADA-compliant parking lot features across Colorado’s Front Range. That includes curb ramps, detectable warning surfaces (the truncated dome panels you see at pedestrian crossings), accessible stall layouts, route slopes, and the signage that ties it all together. We work to current federal ADA standards and Colorado state requirements, and we know what an inspector and a plaintiff’s attorney are each looking for, because we’ve seen plenty of both.
Our ADA compliance clients include property owners, property management companies, HOA boards, retail and restaurant operators, medical and dental office buildings, municipalities, facilities directors, and developers handling new construction or tenant-improvement projects. Some come to us proactively, before a problem develops. Others call after receiving a complaint or a notice of violation. Either way, we assess what’s currently there, tell you what needs to change, and do the work correctly so the issue doesn’t come back.
When we walk a parking lot for an ADA assessment, we follow the same sequence every time. It’s the order an inspector would use, and it’s the order that makes the most sense once you’ve done it a few hundred times. Here’s what we look at, in the order we look at it.
The first thing we check is whether the accessible parking is identified as required by the code, both on the ground and in the air. That means the international symbol of accessibility is painted on the pavement inside each accessible stall, and a vertical post sign is mounted high enough to be visible above a parked vehicle. Van-accessible spaces need their own additional designation. Faded paint, missing signs, signs mounted too low, signs knocked down by a snowplow and never replaced: these are the easiest violations to spot and the easiest for a complainant to photograph. They’re also among the least expensive to correct, which is why it surprises us how often we find them.
Next, we measure the parking stalls themselves. An accessible stall has minimum width requirements, and it needs an adjacent access aisle wide enough for a wheelchair user to deploy a ramp or lift and transfer in or out of the vehicle. Van-accessible spaces require additional width or a wider aisle. The number of accessible spaces required is tied to the total stall count in the lot, so a property that was technically compliant when the lot had 40 spaces may no longer be compliant after a restripe added 20 more. We measure what’s there, count what you have, and compare both to what the lot needs to be in compliance.
An accessible parking space and its adjacent access aisle have to be reasonably flat in both directions. The standard is no more than 2% slope in any direction, whether that’s the direction a person walks or rolls, or the cross slope perpendicular to it. Two percent isn’t much. Many older parking lots in Colorado were graded to drain at 2.5% or 3% across the whole surface, so accessible spaces drain just like the rest of the lot, which fails the standard. We bring a digital level, we measure across the stall and aisle in both directions, and we record what we find. If the slope is wrong, the surface has to be reworked. There’s no striping solution for a grading problem.
From the accessible parking area, a person needs a route to the building, and that route almost always crosses a curb. Current standards require detectable warning surfaces (yellow or contrasting-color panels with raised truncated domes) at the bottom of any curb ramp that connects to a vehicular way. If your ramps were installed before the truncated dome requirement, or if the original panels have worn flat, faded, or popped loose, the ramp isn’t compliant regardless of how the rest of it looks. We install code-compliant panels and replace failed ones as routine work.
A curb ramp can have the right truncated dome panel and still fail compliance if the ramp itself is too steep, too uneven, or has developed cracks and lifts that create trip hazards. The 2% rule applies to cross slopes on the ramp landing, and the running slope has its own maximum. We check the geometry against current standards, then look for spalling concrete, settled panels, lipped joints, and any other surface defect that would catch a cane tip or a wheel. If a ramp can be repaired, we save it. If it can’t, we’ll tell you that and replace it.
The compliance story doesn’t end at the parking area. The path from the accessible stall to the building entrance must maintain the same 2% maximum cross-slope and a reasonable running slope the entire way. We’ve walked routes that started compliant at the stall, climbed a 3% sidewalk for 40 feet, dipped through a drainage swale, and then required a small step up at the door. Each of those segments is a separate potential violation. We measure the whole route, identify the segments that fail, and propose what needs to change. Sometimes it’s a localized grind and overlay. Sometimes it’s a section of new concrete walk. Occasionally, it’s a regrading of the entry approach.
Some properties call us after a complaint has been filed. Some are getting ahead of it because a neighbor down the street just settled a lawsuit, and the word got around. Some are doing a planned resurface or restripe and want the ADA work scoped into the project from the start, which is the cheapest and cleanest way to handle it. And some are buying or selling a property where ADA compliance has surfaced during due diligence and must be addressed before closing. We’ve worked all of these scenarios, and the work itself is largely the same. The trigger just determines the timeline.
If you’re already in a complaint or demand letter situation, the most useful thing we can do quickly is provide a clear, written assessment of what’s currently non-compliant, what it will take to correct it, and a realistic schedule for getting it done. That document on its own often changes the conversation with the complainant or their attorney, because it shows good-faith remediation is in motion.
We handle the full scope of parking lot ADA work, whether that’s a few targeted corrections or a complete reworking of a property’s accessible features. Curb ramp installation and replacement, detectable warning surface installation, regrading of accessible parking areas and access aisles, slope correction on accessible routes, accessible walkway installation, restriping with current ADA layouts, and signage installation and replacement are all part of what we do day to day. When a project calls for it, we coordinate concrete sidewalk replacement and entry threshold work so the entire accessible route functions as a continuous, compliant path, not a chain of individually passing segments with a failure point at every transition.
