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

Restriping an Ontario Lot to ADA Layout

A restripe is the best chance an Ontario property owner gets to fix accessibility problems. Faded paint is the visible reason to repaint — and under the intense Treasure Valley sun, paint here bleaches fast — but underneath it many lots carry layout issues that have been there since the asphalt was first marked: too few accessible spaces, narrow aisles, missing van dimensions, or signage built to Idaho rather than Oregon specs. Repainting over the same lines just preserves those problems.

This guide is for Ontario owners and managers who want the restripe done to current Oregon ADA layout, not merely restored to what was there before. For the statewide foundation, see our ADA parking compliance guide for Oregon.

Get the Stall Dimensions Right Before Paint Touches the Lot

ADA accessible stalls are not standard stalls painted blue. The dimensions are specific:

• Standard accessible stall: minimum 8 feet wide, with an adjacent access aisle at least 5 feet wide.
• Van-accessible stall: minimum 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot aisle. The combined footprint runs 16 feet either way.
• Van count: at least 1 in every 6 accessible stalls must be van-accessible.

Ontario's larger highway-retail lots often need several accessible stalls and more than one van space, and they frequently restripe a row of accessible stalls while shorting the van count. Before any paint goes down, the layout should be chalked and verified against the 2026 ADA striping requirements for Oregon — Oregon's requirements, not Idaho's, govern on the Oregon side of the river.

Access Aisle Striping Is Where Most Lots Fail

The access aisle beside each accessible stall must be striped, not left blank. It needs diagonal hatching across its full length so drivers know not to park there, and many jurisdictions expect "NO PARKING" lettering inside the aisle. The aisle must sit level with the stall and connect to a marked accessible route to the entrance.

When two accessible stalls share one aisle, that shared aisle must still meet the full width requirement. Our ADA access aisle striping spec covers hatch spacing, lettering, and shared-aisle rules.

The Accessibility Symbol and Signage

Each accessible stall gets the International Symbol of Accessibility painted on the pavement, typically white on a blue field, in the correct proportion and orientation. A freehand or undersized symbol invites a complaint. In Ontario, durable paint or thermoplastic is often worth the upcharge because intense high-desert UV and winter sand wear standard paint quickly — a symbol bleached or scraped to half visibility is treated as a compliance gap.

Striping pairs with signage, and this is where border-town lots most often fall short. Each stall needs a vertical sign with the accessibility symbol mounted at least 60 inches to the bottom, a "Van Accessible" plate on van stalls, and Oregon's supplemental fine-amount plate. Idaho-sourced sign kits routinely omit the Oregon fine plate, so a complete Ontario restripe should confirm that plate is present.

Timing the Restripe in Ontario

Striping needs dry pavement and temperatures above 50°F to cure properly. Ontario's high-desert climate gives a long warm season, but avoid the peak of summer heat that can flash-cure paint unevenly, and wait out the freeze risk in spring. Late spring through early fall is the reliable window. Restriping right after a fresh sealcoat gives the new paint better adhesion and contrast, and hands you a blank slate to correct the entire accessible layout.

A Practical Restripe Sequence

1. Count existing spaces and check the required accessible and van count against your total.
2. Measure existing accessible stalls and aisles for width and slope.
3. Chalk the corrected layout — stalls, aisles, hatching, symbol locations.
4. Verify the accessible route from the stalls to the entrance is continuous and marked.
5. Apply durable paint in dry, warm conditions.
6. Update or install compliant signs at the correct height with the Oregon fine plate.
