ADA Parking Striping in Tualatin, Oregon: Bringing Your Lot Up to Code

Restriping a Tualatin Lot to ADA Standards

In Tualatin, most ADA parking problems are striping problems — stalls painted too narrow, access aisles missing their hatching, and wheelchair symbols worn down by Tualatin Valley rain and the city's heavy retail and truck traffic. Restriping is the step that turns a non-compliant Washington County lot into a compliant one, and for most owners it is the most cost-effective correction available.

This page covers what ADA-compliant striping involves in Tualatin. For the legal backdrop, see our Oregon ADA parking compliance pillar; for the dimension and paint specs statewide, our Oregon ADA striping requirements for 2026 guide goes into detail.

What an ADA-Compliant Stripe Job Includes

A correct accessible stall means getting all of these right:

• Stall width: at least 8 feet for a standard accessible space; 8 feet for a van stall with the wider aisle, or 11 feet with a 5-foot aisle.
• Access aisle: 5 feet wide for car stalls, 8 feet for van stalls, with diagonal hatching and ideally "NO PARKING" lettering.
• The symbol: the International Symbol of Accessibility in each stall, white on blue.
• Borders and contrast: blue outlines that stay legible on fresh, dark asphalt.

The access aisle is the part Tualatin owners most often misunderstand. It is the transfer zone a wheelchair user needs beside the vehicle, and it must connect to an accessible route to the entrance — not double as overflow parking, a real temptation in Tualatin's busy destination-retail lots. Our ADA access aisle striping spec covers the hatching and shared-aisle rules.

Layout Before Paint

The most valuable step in a Tualatin ADA restripe comes before the paint: confirming the layout is correct. Tualatin's range of lot types — polished retail, office, and large industrial — means a range of layout issues, from outdated counts on older office lots to van-ratio shortfalls on industrial lots that see larger vehicles. A proper layout pass checks the accessible count against the total, confirms the one-in-six van ratio, verifies aisle widths and placement, and positions stalls on the shortest accessible route to the entrance.

For Tualatin's big retail centers, that route accuracy means distributing accessible stalls across the frontage so each anchor and storefront has nearby accessible parking.

Paint, Climate, and Durability in Tualatin

Tualatin's wet valley climate fades water-based traffic paint within 12 to 24 months, and the city's high-volume retail and industrial traffic adds heavy mechanical wear — tires in retail lots, trucks and trailers in distribution lots — so markings here often deteriorate faster than in quieter areas. Because a faded accessible marking can be cited as a violation, durability is a compliance concern.

Tualatin owners can reach for longer-lasting materials: oil-based traffic paint adheres better than latex, and thermoplastic markings — several times the cost — can hold three to five years even under heavy traffic, often paying off in fewer restripe cycles on busy or industrial lots. Timing matters too: the Tualatin striping season runs late spring through early fall, and scheduling for the drier June-to-September window gives paint the best chance to bond before the rains return.

Restriping After Sealcoat

Tualatin owners frequently pair an ADA restripe with a sealcoat. The order matters: sealcoat first, cure, then stripe onto the clean dark surface for maximum contrast and adhesion. A fresh sealcoat is the ideal moment to correct an ADA layout because the old lines are gone — a blank slate to fix counts, widen aisles, and reposition van stalls without fighting old paint. On Tualatin's drainage-prone lots, pairing the work with any grading correction makes the whole job more durable.
