ADA Parking Lot Compliance in The Dalles, Oregon: 2026 Guide

The Dalles is the Wasco County seat and the commercial anchor of the eastern Columbia River Gorge, where the wet western climate gives way to drier, colder, windier high-desert conditions. That transition zone is unusually tough on parking lots. Hard winter freezes settle asphalt, intense summer sun fades paint, and the Gorge's relentless wind stresses every sign post in town. For The Dalles property owners, ADA parking compliance is an ongoing job, not a one-time project, because the climate constantly works against it.
This 2026 guide covers the accessible parking requirements that apply to businesses in The Dalles: how many accessible spaces you need, the dimensions and signage that make them compliant, and the slope and surface standards that keep them that way. It builds on our statewide Oregon ADA parking compliance guide, the pillar resource behind every figure here.
The count is set by the 2010 ADA Standards and scales with total stalls.
| 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 |
The access aisle must be level with the stall and connect to a continuous accessible route to the entrance. Two accessible stalls may share one aisle.
Each accessible stall in The Dalles needs a vertical sign with the International Symbol of Accessibility mounted at least 60 inches from the ground to the bottom of the sign, visible when a vehicle is parked. Van stalls add a "Van Accessible" plate, and Oregon requires a supplemental sign stating the fine for illegally parking in an accessible space. The Gorge wind is a real factor here: it leans posts, loosens fasteners, and bends signs over time, which can pull a sign below the required height or out of view. Checking that signs remain upright, secure, and at the correct height should be part of routine maintenance in The Dalles. See our ADA parking sign placement guide for mounting detail.
Slope is where The Dalles lots most often slip out of compliance. The 2 percent cap on accessible stalls and aisles applies to the finished, settled surface, not the day the lot was poured. The Gorge's hard freeze-thaw cycling works the base material, and over a few winters a stall that started at 1.8 percent can drift past 2 percent. The change is too small to see, so a measured check with a level is the only reliable test. Settlement near catch basins and the edges of older patches is the usual offender.
The Dalles combines hard winters, blowing grit, and intense summer UV, which fades traffic paint faster than the milder western valleys. Faded accessible markings are treated as a compliance gap, not just a cosmetic issue, so the climate effectively shortens the compliance window. The same freeze-thaw action opens cracks and lifts edges in accessible stalls and along the route to the door, creating trip hazards. For owners in The Dalles:
A full repave or significant reconstruction of a lot in The Dalles is an alteration under the ADA, triggering the obligation to bring the path of travel up to current standards to the maximum extent feasible. Routine maintenance, including sealcoating, crack sealing, and restriping existing markings, does not trigger upgrades, but you cannot make the lot less accessible than it already is. Audit during the design stage of any repave so counts, slopes, and the route get corrected while the asphalt is open. For how a structured inspection works, see our ADA compliance audit process.
Most compliance work in The Dalles is restriping, signage, and targeted surface repair. If your lot is due for fresh lines, fold the ADA corrections into a scheduled restripe to share mobilization cost. Local pricing, durable paint options, and seasonal timing are covered in our parking lot striping in The Dalles guide.
The counts, dimensions, and slope limits here are general guidance based on the 2010 ADA Standards and ORS 447.233. Your lot's actual compliance depends on measured conditions, so have a qualified contractor or accessibility professional perform a survey before committing to corrections.
