ADA Parking Lot Compliance in Scappoose, Oregon: 2026 Guide

Scappoose sits along the Highway 30 corridor in Columbia County, a fast-growing commuter town between Portland and St. Helens with a steady mix of retail strips, light industrial and warehouse properties, the Scappoose Industrial Airpark, and a commercial core serving a bedroom community that drives to the metro for work. That blend — high-turnover storefronts plus larger fleet-and-warehouse lots — gives Scappoose a wide range of parking lot types, and each carries the same baseline ADA obligations.
For Scappoose business owners and property managers, accessible parking compliance is both a legal duty under the Americans with Disabilities Act and Oregon law, and a practical service to customers, employees, and visitors with disabilities. This guide is a 2026 overview of what compliance requires under the 2010 ADA Standards and Oregon's accessible parking statute, ORS 447.233. It complements rather than repeats our statewide ADA parking compliance guide for Oregon.
Required accessible spaces scale with total lot capacity at roughly one space per 25.
| 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 Scappoose's industrial and warehouse properties, remember that employee parking counts toward the total just like customer parking — a large staff lot still needs its proportional accessible spaces.
Van-accessible spaces matter more than usual at Scappoose's industrial and fleet properties, where larger adapted vehicles are more common and side-deploying lifts need the wider aisle.
Accessible stalls and their access aisles cannot exceed 2 percent slope in any direction on the finished surface. The accessible route from parking to the entrance cannot exceed 5 percent running slope and 2 percent cross slope. Large flat warehouse lots can develop drainage-driven slope issues over time; standing water in an accessible space is a warning sign.
Every accessible stall needs an access aisle marked with diagonal hatching, kept flush and level with the stall, and connected to an accessible route to the entrance. Two stalls may share one aisle. No vehicle may park or stand in an aisle — a real discipline issue at busy industrial lots where staging and deliveries crowd the pavement.
Each accessible space needs a vertical sign with the International Symbol of Accessibility, mounted so the bottom of the sign sits at least 60 inches above the ground and stays visible over a parked vehicle. Van-accessible stalls add a "Van Accessible" plate. Oregon also requires a supplemental sign stating the fine for parking illegally in an accessible space. Our guide to ADA parking sign placement in Oregon covers mounting height and the Oregon fine-plate requirement in detail.
ADA compliance extends to keeping surfaces in good condition. The accessible route from stalls to entrance must stay free of:
Scappoose's wet lower-Columbia winters and freeze-thaw cycles attack asphalt every year, and heavy truck traffic at industrial lots accelerates surface wear. Prioritizing accessible areas in spring maintenance keeps them compliant.
Routine maintenance — sealcoating, crack sealing, patching, restriping existing markings — does not trigger new ADA obligations. But a full repave or significant reconstruction counts as an "alteration," obligating you to bring the path of travel into compliance to the maximum extent feasible, up to 20 percent of the project cost. For Scappoose's larger industrial lots, where repaving is a significant investment, an audit beforehand lets you fold compliance work into the same project. See our overview of the ADA compliance audit process.
Across Columbia County, a few issues recur:
Most are inexpensive striping and signage corrections; slope and drainage work are the larger items.
Compliance work is priced as a range, and actual costs depend on condition and scope. A complete ADA-compliant accessible stall — symbol stencil, hatched aisle, and signage — has been baselined around $200 to $350 per space. Signage runs roughly $100 to $300 per sign installed. Slope correction and route repair are larger, variable line items. A site visit is the only way to get an accurate figure. See our professional striping services for what a Cojo project includes.
