ADA Parking Lot Compliance in Mcminnville, Oregon: 2026 Guide

ADA Parking Compliance for McMinnville Property Owners

McMinnville is the seat of Yamhill County and the commercial hub of Oregon wine country, with Highway 99W and Highway 18 funneling visitors past the historic Third Street district, the tasting rooms, and the medical and retail corridors along Lafayette Avenue. Tourist-heavy lots see hard, constant use — which makes accessible parking both a legal obligation and a practical part of serving every customer who pulls in.

If you own or manage a property in McMinnville, your lot has to meet the 2010 ADA Standards for Accessible Design and Oregon's accessible parking statute, ORS 447.233. This guide explains what compliance looks like locally. It is general guidance, not a substitute for a site survey, but it will tell you what an inspector or a plaintiff's attorney looks for.

How Many Accessible Spaces Does Your McMinnville Lot Need?

The federal count table sets the floor: one accessible space per 25 in the lower ranges, tapering as lots grow.

Total Spaces	Required Accessible	Van-Accessible Minimum
1–25	1	1
26–50	2	1
51–75	3	1
76–100	4	1
101–150	5	1
151–200	6	1

At least one in every six accessible spaces, rounded up, must be van-accessible. A Third Street tasting room with 28 spaces needs two accessible stalls, one of them van-accessible. Outpatient medical clinics along Lafayette Avenue carry a 10 percent ratio, and rehab and physical therapy practices 20 percent.

Stall and Access Aisle Dimensions

Older McMinnville lots, especially around the historic downtown, often predate current geometry rules.

• Standard accessible stall: at least 8 feet wide with a 5-foot access aisle
• Van-accessible stall: 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot aisle
• Vertical clearance: 98 inches along the van route, at the stall, and at the aisle
• Access aisle: marked with diagonal hatching, kept clear, tied to an accessible route to the entrance

Two adjacent stalls can share one access aisle. The aisle must sit at the same level as the stall, with no lip at the boundary.

Slope: the 2 Percent Rule

Accessible stalls and aisles cannot exceed 2 percent slope in any direction. McMinnville's older downtown lots and the sites that step up from the highway grade are prone to drifting out of tolerance as the base settles. The only reliable check is to measure the finished surface with a digital level. Ponding water in an accessible aisle is a warning sign that slope has gone out of range.

Signage Requirements

Every accessible space in Oregon needs a vertical sign with the International Symbol of Accessibility mounted at least 60 inches to the bottom of the sign, a "Van Accessible" plate where required, and Oregon's supplemental fine plate. Our guide on ADA parking sign placement and mounting covers heights, sign types, and the fine plate.

Surface and Maintenance

Compliance extends to the surface. The accessible route and stalls must stay firm, stable, and slip-resistant. McMinnville's wet Willamette Valley winters drive crack growth and the occasional pothole that can turn an accessible route into a trip hazard by spring. Level changes over a quarter inch, cracks wider than half an inch, potholes, and ponding water are all potential violations — prioritize these zones in your maintenance plan.

What Triggers an Upgrade

Routine maintenance — sealcoating, crack filling, patching, restriping existing markings — does not trigger new ADA obligations. A full repave or reconfiguration is an alteration and brings the path-of-travel rule into play, requiring up to 20 percent of project cost to go toward accessibility when the existing route is not compliant.

Bringing a McMinnville Lot Into Compliance

1. Count total and accessible spaces against the table
2. Measure stall and aisle widths
3. Check slope on every accessible stall and aisle
4. Verify sign height, van designation, and the Oregon fine plate
5. Inspect the accessible route for trip hazards
6. Document everything and fix the cheapest, highest-risk items first
