What Are ADA Parking Requirements?

The Americans with Disabilities Act (ADA) is a federal law that ensures equal access for individuals with disabilities in public spaces, including parking lots and pedestrian areas. Under the ADA, property owners are required to provide properly marked and accessible parking spaces. ADA-compliant parking lots must feature clear striping, compliant signage, and barrier-free routes from parking areas to building entrances.

ADA Requirements:

Minimum number of accessible spaces: At least one accessible space per 25 standard parking spots (with variations by lot size).

Van-accessible spaces: At least one of every six accessible spaces must be van-accessible, featuring an 8-foot access aisle.

Signage height and visibility: ADA-compliant signs must be posted at least five feet above the ground for clear visibility.

Proper pavement marking: Blue striping, access aisles, and international accessibility symbols must be durable and easily identifiable.

Barrier-free access: Ramps, curbs, and pathways must provide smooth, unobstructed access to entrances.

Following these requirements helps protect your business from liability, enhances visitor safety, and promotes inclusivity for all customers and employees.

ADA-Compliant Parking Lot Striping

Our crews specialize in pavement marking layouts that meet all ADA and state-level design standards. We accurately measure and mark accessible stalls, van-accessible spaces, and access aisles, using durable traffic-grade paint for long-lasting visibility.

Curb Ramps & Pedestrian Pathway Markings

Properly marked and graded ramps provide seamless access from parking areas to sidewalks and building entrances. Chamberlain designs and installs ADA-compliant ramps and directional arrows to create safe pedestrian routes that meet slope and surface standards.

Detectable Warning Surfaces

We install tactile or truncated dome surfaces that assist visually impaired pedestrians. These detectable warning systems are made from durable, high-contrast materials and installed at key transition points such as crosswalks, ramps, and curb edges.

Crosswalks & Pedestrian Safety Zones

Well-defined crosswalks and safety zone markings enhance visibility and reduce the risk of accidents near building entrances, schools, and commercial areas. We use reflective and weather-resistant coatings to maintain bright, consistent markings year-round.

Directional & Accessibility Signage

We provide and install ADA-compliant signage that clearly identifies accessible parking, routes, and building entrances. Each sign is placed at the correct height and angle for maximum visibility and durability.

Ongoing Maintenance & Re-Striping

Fading lines can lead to compliance issues. Chamberlain offers repainting, re-striping, and routine parking lot maintenance services to preserve ADA compliance and surface utility over time.

Our ADA Pavement Marking Process Works

Every project begins with a detailed site evaluation to ensure our work is performed efficiently and yields lasting results. Our process is designed to minimize disruptions while keeping your lot accessible at all times.

1) Site Evaluation & Compliance Audit

We start by assessing your current parking layout, slopes, signage, and striping. Our experts identify deficiencies and create a detailed compliance report to guide upgrades.

2) Design & Plan Adjustments

Next, we develop a new layout plan with accurate spacing for accessible and van-accessible stalls. We also mark signage placement and access routes to ensure all requirements are met.

3) Pavement Marking & Signage Installation

Our crew installs all necessary line striping, stenciling, and pavement markings using high-visibility coatings. ADA-compliant signs are installed at the correct height and position for easy recognition.

4) Surface & Ramp Adjustments

If slope corrections, resurfacing, or curb ramp installations are required, our in-house team will make the necessary adjustments.

5) Final Inspection & Certification

Before wrapping up, we conduct a comprehensive walkthrough and inspection to ensure your lot meets all applicable federal, state, and local ADA standards. You’ll receive photos and documentation for your property records and future reference.
