ADA Parking Lot Compliance in Gladstone, Oregon: 2026 Guide

Gladstone is a compact Clackamas County city wedged between Oregon City and Milwaukie, where the Clackamas and Willamette rivers meet. Most of the commercial activity here clusters along Portland Avenue and McLoughlin Boulevard — older strip retail, churches, medical offices, and the kind of small-footprint lots that were paved decades before anyone measured an access aisle. That history is exactly why ADA compliance trips up Gladstone owners: a lot that has served customers for thirty years is not automatically compliant, and there is no grandfather clause that excuses it.
If you own or manage commercial property in Gladstone, the Americans with Disabilities Act (Title III) applies to your parking the moment the public can use it. This guide walks through what compliance actually looks like on a Gladstone lot. For the full statewide picture, start with our ADA parking compliance guide for Oregon, then come back here for the local detail.
The 2010 ADA Standards set the count by total spaces in the lot. The ratio starts at one accessible space per lot and scales up.
| Total Spaces | Required Accessible Spaces |
|---|---|
| 1–25 | 1 |
| 26–50 | 2 |
| 51–75 | 3 |
| 76–100 | 4 |
| 101–150 | 5 |
| 151–200 | 6 |
| 201–300 | 7 |
Dimensions are where older Gladstone lots most often fall out of compliance, usually because someone restriped over faded lines without measuring.
The access aisle is not decorative. It is the striped, hatched zone beside the stall that lets a wheelchair user deploy a ramp or lift. It must connect to an accessible route to the door, sit at the same level as the stall, and carry "NO PARKING" so drivers do not block it. Two adjacent accessible stalls can share one aisle between them.
Every accessible stall and its aisle must stay under 2 percent slope in all directions. Gladstone's riverside terrain and the gentle grades around Portland Avenue mean some lots were marginal when built and have drifted out of tolerance as the asphalt settled. A stall that measures 2.4 percent is a violation even if it looks flat to the eye. Slope problems usually require regrading or an asphalt patch rather than paint, so they are worth catching early. The same 2 percent cross-slope cap applies to the accessible route from the stall to the building entrance.
Federal rules require a sign at every accessible stall showing the International Symbol of Accessibility, mounted so the bottom of the sign sits at least 60 inches above the pavement. Van stalls add a "Van Accessible" plate below it. Oregon layers on a requirement that catches a lot of out-of-state owners off guard: under ORS 447.233, accessible parking signs in Oregon must also display the dollar amount of the fine for illegal parking in the space. A sign that is missing the Oregon fine plate is technically non-compliant even when it meets every federal spec. See ADA parking sign placement for mounting detail.
The wet Willamette Valley winters and summer UV that Gladstone shares with the rest of the Portland metro fade traffic paint faster than owners expect. Faded accessibility symbols, washed-out aisle hatching, and a barely-visible blue stall border are not cosmetic problems — markings that can no longer be clearly read can be cited as compliance failures. Plan to inspect striping annually and repaint the accessibility symbol, aisle hatching, and stall borders before they drop below clear visibility. A fresh, high-contrast symbol painted in each stall is the cheapest insurance you can buy against a complaint.
Routine maintenance — sealcoating, crack filling, pothole patching, restriping existing lines — does not trigger new ADA obligations, though you can never make the lot less accessible than it already is. But an alteration does. If you overlay, reconstruct, regrade, or expand a Gladstone lot, you trigger the obligation to bring the altered area and the path of travel up to current standards to the maximum extent feasible. That is the moment to fix counts, widen aisles, and correct slope, because the lot is already torn up and the work is far cheaper bundled into the larger project than done piecemeal later.
Most Gladstone lots that fail an audit fail on two or three of these, not all of them — which means compliance is usually a focused fix, not a full rebuild. The honest way to know where you stand is a measured assessment.
