ADA Parking Lot Striping in Denver, CO

Enright Asphalt provides ADA-compliant parking lot striping for commercial and multi-family properties across Denver and the Front Range. We lay out and mark accessible parking spaces, van-accessible spaces, access aisles, signage, and accessible routes in full compliance with the 2010 ADA Standards for Accessible Design. Non-compliant parking lots face federal civil penalties up to $75,000 for a first violation and $150,000 for subsequent violations, plus private lawsuits that can add tens of thousands more in legal fees and settlements.

We’ve been striping parking lots in the Denver metro for over 30 years. We hold an A+ BBB rating and our crews know the federal ADA requirements, Colorado-specific regulations, and local municipal codes that apply to accessible parking. When we stripe your lot, you get markings that pass inspection and protect you from the fines and litigation that come with non-compliance.

Compliance Costs Less Than a Violation

ADA parking violations are among the most common accessibility complaints filed with the Department of Justice. Faded markings, missing access aisles, wrong dimensions, or absent signage can all trigger a complaint. According to ADA.gov, restriping is considered “readily achievable” for most businesses, which means the law expects you to have it done. Not having compliant striping when it’s this straightforward to fix is hard to defend.

The cost of bringing a parking lot into ADA compliance is a fraction of what a single violation costs. Federal civil penalties start at $75,000 for a first offense. Private lawsuits routinely settle for $5,000 to $50,000 per violation. Attorney’s fees in accessibility cases often run $50,000 to $200,000 or more. Getting your striping right the first time is the simplest way to avoid all of it.

Protect Your Property, Protect Your Tenants

For property managers, ADA compliance isn’t just about avoiding fines. It’s about reducing liability exposure, maintaining tenant confidence, and ensuring everyone who visits your property can access it safely. A parking lot with properly marked accessible spaces, correctly sized access aisles, and visible signage tells tenants and customers that you take maintenance seriously.

Compliance also comes into play during property transactions, tenant lease negotiations, and insurance reviews. A documented ADA-compliant lot is a cleaner file than one with known deficiencies. We provide documentation of work completed so you have records for your files.

How Many Accessible Spaces Does Your Lot Need

The 2010 ADA Standards for Accessible Design set minimum requirements based on total parking count. The number is calculated separately for each parking facility, not combined across a site. Here’s the requirement table from the federal standards:

Medical facilities have higher requirements. Hospital outpatient facilities need 10% of patient and visitor parking to be accessible. Rehabilitation and physical therapy facilities need 20%. One of every six accessible spaces, or fraction of six, must be van-accessible in all cases.

ADA Parking Space and Aisle Dimensions

Getting the dimensions right is where many parking lots fall out of compliance. Here are the key measurements from the 2010 ADA Standards:

Car-Accessible Spaces

Minimum 96 inches (8 feet) wide with an adjacent access aisle of at least 60 inches (5 feet). The access aisle must be the same length as the parking space it serves. Two spaces can share one access aisle. Maximum slope in all directions is 1:48.

Van-Accessible Spaces

Two configurations meet the standard. Option one: 132 inches (11 feet) wide with a 60-inch (5-foot) access aisle. Option two: 96 inches (8 feet) wide with a 96-inch (8-foot) access aisle. The wider aisle in option two accommodates van side-loading ramps and wheelchair lifts. Van-accessible spaces require a “Van Accessible” sign in addition to the International Symbol of Accessibility.

Access Aisles

Access aisles must be clearly marked with diagonal hatch lines in a contrasting color to discourage parking. The surface must be firm, stable, and slip-resistant with no changes in level. The aisle must connect to an accessible route leading to the building entrance. Curb ramps cannot extend into the access aisle.

Signage

Every accessible space needs a pole-mounted sign with the International Symbol of Accessibility, mounted at least 60 inches above the ground. The sign must be visible from the parking space even when a vehicle is parked. Van-accessible spaces need an additional “Van Accessible” designation. Pavement stencils alone don’t satisfy the signage requirement. You need both the ground marking and the pole-mounted sign.

How We Stripe ADA-Compliant Parking

ADA striping requires precision. Getting a space two inches too narrow or missing a sign can make the entire space non-compliant. Here’s our process:

1. Audit the existing lot. We count total spaces, identify current accessible spaces, and check compliance on each one: dimensions, access aisle width, slope, signage height, route connections, and curb ramp placement. We flag every deficiency.
2. Design the compliant layout. Based on total parking count and the ADA requirements table, we determine how many accessible spaces and van-accessible spaces your lot needs. We position them on the shortest accessible route to each building entrance. If your lot serves multiple entrances, we disperse accessible spaces accordingly.
3. Prepare the surface. We clean the striping area and, if needed, remove old markings that conflict with the new layout. On freshly sealcoated lots, we coordinate timing so paint goes down after the sealcoat has cured.
4. Stripe accessible spaces and access aisles. We mark each space and aisle to exact ADA dimensions using contrasting, high-visibility paint. Access aisles get diagonal hatch lines. Pavement stencils for the International Symbol of Accessibility are applied within each space.
5. Install signage. We install pole-mounted ADA signs at the required 60-inch minimum height. Van-accessible spaces get the additional “Van Accessible” designation. Signs are positioned to remain visible when a vehicle is parked in the space.
6. Mark accessible routes. Where the accessible route from parking to the building entrance crosses vehicular traffic lanes, we mark the pedestrian path with contrasting paint. We verify the route connects to compliant curb ramps where grade changes exist.
7. Final verification. We walk the finished layout and verify every dimension, sign, slope, and route connection before we leave. You get a documented record of the work completed.

Common ADA Striping Mistakes We Fix

We see the same compliance failures regularly on Denver parking lots. If any of these apply to your property, you’re at risk:

• Access aisles too narrow or missing entirely. A space without a properly sized access aisle is non-compliant, even if the space itself is the right width.
• No van-accessible spaces. Every lot needs at least one van-accessible space. Many lots skip this or don’t provide the wider aisle configuration.
• Signage missing or mounted too low. Pavement stencils without pole-mounted signs don’t meet the standard. Signs below 60 inches are also non-compliant.
• Accessible spaces not on the shortest route to the entrance. Placing accessible spots in a back corner away from the building defeats the purpose and violates the standard.
• Faded markings that are no longer clearly visible. The ADA requires accessible spaces to be clearly marked. Faded stripes can trigger a complaint.
• Curb ramps extending into access aisles. The ramp must not block or reduce the access aisle. This is a common design error.
• Slopes exceeding 1:48 in accessible spaces. Denver parking lots on sloped terrain need extra attention to meet the maximum grade requirement.

If you’re unsure whether your lot is compliant, we offer ADA compliance audits. We’ll walk the property, check every element, and give you a prioritized list of what needs to be corrected.

What Affects Your ADA Striping Project

Every property is different. Here are the main factors:

• Total parking count and number of accessible spaces required
• Whether the project is new striping, re-striping, or targeted corrections
• Number of building entrances and accessible route connections needed
• Whether curb ramp installation or modification is required (separate scope)
• Signage quantity and whether existing posts can be reused
• Surface condition (freshly sealcoated, aged pavement, or recently paved)
• Lot layout complexity (angled parking, multi-level structures, shared aisles)
• Local municipal code requirements beyond federal ADA minimums

Every project is different. Call Enright Asphalt at 720-637-4960 for a free estimate so you know exactly what you’re getting into before any work starts.

Frequently Asked Questions

Does restriping my parking lot trigger ADA requirements?

Yes. According to ADA.gov, when a business or government entity restripes a parking lot, it must provide accessible parking spaces as required by the 2010 ADA Standards. Because restriping is relatively inexpensive, it’s considered readily achievable, which means the law expects you to include compliant accessible spaces every time you re-stripe.

What colors are required for ADA parking striping?

The federal ADA standards don’t mandate specific colors, but they require contrasting paint that’s clearly distinguishable from the pavement surface. Most municipalities and states, including Colorado, use blue and white for accessible spaces and yellow for standard spaces. Check your local code for specific color requirements.

Do I need both a pavement stencil and a pole-mounted sign?

Yes. The 2010 ADA Standards require a parking space identification sign with the International Symbol of Accessibility mounted at least 60 inches above the ground. A pavement stencil alone doesn’t satisfy this requirement. You need both the ground marking and the sign.

Can two accessible spaces share one access aisle?

Yes, for standard perpendicular parking. Two spaces can share a single access aisle between them. The exception is angled parking, where the access aisle must be on the passenger side of each space. Shared aisles are a common way to fit more accessible spaces without losing additional parking.

How do I know if my lot’s accessible spaces are on the right slope?

The maximum slope allowed for accessible spaces and access aisles is 1:48 in all directions, which is approximately 2%. We check slopes during our audit using a digital level. Denver lots built on sloped terrain often have spots that exceed this threshold, which makes them non-compliant even if the dimensions are correct.

Do you install ADA curb ramps as part of the striping project?

We can coordinate curb ramp installation alongside your striping project. Curb ramp construction is a separate scope of work, but we frequently do both on the same property. Having one contractor handle striping and ramps ensures the accessible route connects properly from the parking space through the ramp to the building entrance.
