Oregon City sits at the southern edge of the Portland metro, where Highway 213, McLoughlin Boulevard (OR-99E), and Molalla Avenue carry steady commercial traffic past the historic district and the Willamette Falls. If you own or manage a retail center, medical office, church, or apartment community in Clackamas County, your parking lot has to meet the accessibility requirements set by the 2010 ADA Standards for Accessible Design and Oregon's own accessible parking statute, ORS 447.233.
This guide walks through what compliance actually looks like on the ground in Oregon City. It is general guidance, not a substitute for a site-specific survey, but it will help you understand what an inspector, a plaintiff's attorney, or a building official looks for when they evaluate your lot.
For the statewide picture, start with our Oregon ADA parking compliance guide, which this page builds on.
The federal count table is the foundation. You provide one accessible space for every 25 total spaces in the lower ranges, and the ratio tapers as lots grow larger.
| 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 |
For the full count breakdown including large lots over 500 spaces, see our guide on how many accessible spaces your lot needs.
Getting the geometry right is where many older Oregon City lots fall short, especially properties laid out before the 2010 Standards took effect.
Two adjacent stalls can share a single access aisle. The aisle must sit at the same level as the parking space, with no lip or drop-off at the boundary.
Accessible stalls and their access aisles cannot exceed 2 percent slope in any direction. This is the single requirement Oregon City's terrain most often breaks. The land around Beavercreek Road and the bluff above the falls is anything but flat, and a lot that was compliant at construction can drift out of tolerance as the base settles or after a regrade.
The only reliable way to confirm slope is to measure it with a digital level or survey instrument across the finished surface. If your lot has visible cross-fall on the accessible stalls or ponding water in the aisle, treat that as a red flag and have it checked.
Every accessible space in Oregon needs a vertical sign with the International Symbol of Accessibility, mounted so the bottom of the sign is at least 60 inches above the surface. Van spaces add a "Van Accessible" designation. Oregon also requires a supplemental plate stating the fine for unauthorized parking — a state-specific overlay on top of the federal sign rules.
Our deep dive on ADA parking sign placement and mounting covers the height, sign types, and the Oregon fine plate in detail.
ADA compliance does not stop at the stripe. The accessible route and stalls must stay firm, stable, and slip-resistant. In a freeze-prone area like Oregon City, winter heaving and crack growth can introduce trip hazards by spring. Level changes over a quarter inch, cracks wider than half an inch, potholes, and ponding water in accessible areas are all potential violations. Prioritize these zones in your seasonal maintenance plan.
Routine maintenance — sealcoating, crack filling, patching, and restriping existing markings — does not trigger new ADA obligations. A full repave or reconfiguration counts as an alteration and brings the path-of-travel rule into play, requiring you to spend up to 20 percent of the project cost on accessibility improvements when the existing route is not compliant.
If you are planning new striping or a fresh layout, see how local crews handle parking lot striping in Oregon City, and review the ADA compliance audit process before you commit to a scope.
