ADA Parking Lot Compliance in Warrenton, Oregon: 2026 Guide

ADA Parking Compliance in Warrenton

Warrenton is the retail hub of Oregon's North Coast. Sitting at the mouth of the Columbia just west of Astoria in Clatsop County, this Highway 101 town packs in the big-box stores, shopping centers, and chain restaurants that serve the entire lower-Columbia region and the steady stream of tourists heading to Fort Stevens, the beaches, and the river. That means Warrenton has some of the largest, highest-traffic parking lots on the coast — and big lots carry big accessible-parking obligations.

For Warrenton business owners and property managers, ADA compliance is both a legal duty under the Americans with Disabilities Act and Oregon law, and a practical service to a high volume of customers and tourists 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, with attention to the coastal conditions that make Warrenton lots harder to maintain. It complements rather than repeats our statewide ADA parking compliance guide for Oregon.

How Many Accessible Spaces Warrenton Lots Need

Required accessible spaces scale with total lot capacity at roughly one space per 25 — but Warrenton's big-box lots push into the higher tiers where the math changes.

Total Spaces	Required Accessible	Van-Accessible Minimum
76–100	4	1
101–150	5	1
151–200	6	1
201–300	7	2
301–400	8	2
401–500	9	2
501–1000	2% of total	1 per 6 accessible

At least one in every six accessible spaces, rounded up, must be van-accessible — so a big-box lot with seven accessible spaces needs at least two van-accessible. A 350-stall shopping-center lot needs eight accessible spaces, two van. Smaller storefronts follow the lower tiers (one space for 1–25, and so on). The complete table is in our guide to how many accessible spaces your lot needs.

For Warrenton's large retail lots, accessible spaces should also be distributed across multiple entrances and storefronts, not clustered at one end, so each entrance has the shortest accessible route.

Stall, Aisle, and Slope Requirements

Stall Dimensions

• Standard accessible stall: minimum 8 feet wide with a 5-foot access aisle
• Van-accessible stall: minimum 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot aisle

The 2% Slope Rule

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. Warrenton's flat, low-lying coastal terrain and high water table make drainage the dominant slope concern — large lots are graded for runoff, and ponding water in an accessible space signals a slope problem.

Access Aisles

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. Cart corrals at big-box lots must be positioned so they never block accessible spaces or aisles.

Signage Requirements

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 requires a supplemental sign stating the fine for parking illegally in an accessible space. Coastal salt air is hard on sign hardware and posts, so corrosion-resistant mounting matters here. Our guide to ADA parking sign placement in Oregon covers mounting height and the Oregon fine plate.

Coastal Surface and Route Maintenance

ADA compliance extends to surface condition, and Warrenton's coastal environment is uniquely tough on pavement and markings:

• Salt air accelerates oxidation of asphalt and corrosion of sign hardware
• Constant moisture fades traffic paint faster than inland conditions
• High water table and heavy rain drive drainage and ponding issues in accessible areas
• Wind-driven grit scours painted symbols and markings

The accessible route from stalls to entrance must stay free of level changes over a quarter inch, cracks wider than a half inch, potholes, standing water, and loose surface. On the coast, accessible markings often need inspection and refresh more frequently than the inland 12-to-24-month cycle.

When Repaving Triggers Upgrades

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 Warrenton's large retail lots, where repaving is a major investment, auditing first lets you fold compliance into the same project. See our overview of the ADA compliance audit process.

What Compliance Costs

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, drainage work, and route repair are larger, variable line items, and coastal conditions can shorten the interval between refreshes. A site visit is the only way to get an accurate figure. See our professional striping services for what a Cojo project includes.
