ADA Parking Lot Compliance in Phoenix, Oregon: 2026 Guide

ADA Parking Compliance in Phoenix

Phoenix sits along the I-5 corridor in Jackson County, between Medford and Talent at the heart of the Rogue Valley. Like its neighbors, Phoenix has seen significant rebuilding and new commercial development in recent years, which makes accessibility a front-of-mind issue: new construction and major reconstruction must meet current ADA standards from the design stage. Whether you own a Main Street storefront, a highway-frontage business, or an office near the interchange, your parking lot carries the same federal ADA and Oregon accessibility obligations as any commercial property statewide.

Compliance is a legal duty and a practical one. Non-compliance exposes a Phoenix business to federal civil penalties, private lawsuits with attorney fees, and Oregon state enforcement — and accessible parking decides whether all of your customers can reach the door. This 2026 guide covers the essentials. For the full statewide picture, start with our ADA parking compliance guide for Oregon.

How Many Accessible Spaces Phoenix Lots Need

The required accessible count scales with total parking under the 2010 ADA Standards for Accessible Design:

Total Parking Spaces	Required Accessible Spaces	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

At least one of every six accessible stalls (rounded up) must be van-accessible. Most Phoenix lots — a retail storefront, a restaurant, a clinic — sit in the lower tiers and need one or two accessible stalls, with the first always van-accessible. Outpatient medical and rehabilitation facilities carry higher ratios (10 to 20 percent). Our how many accessible spaces your lot needs page covers the full table and rounding rules.

Stall and Aisle Dimensions

• Standard accessible stall: minimum 8 feet wide with a 5-foot access aisle.
• Van-accessible stall: 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot aisle.
• Vertical clearance: 98 inches along the van route, at the stall, and through the aisle.
• Access aisle: diagonal hatching plus NO PARKING, level with the stall, connected to a continuous accessible route to the entrance.

Two accessible stalls can share one aisle between them. The aisle must never be parked in or blocked.

The 2% Slope Rule

Accessible stalls and their aisles must not exceed 2 percent slope in any direction on the finished surface. The Rogue Valley floor through Phoenix is fairly level, but lots built on fill, against grade, or near the interchange embankments can run steeper than they appear, and settlement pushes slopes out of tolerance. A stall that looks flat may measure 3 or 4 percent — a violation. Verifying slope takes a level, and where it fails, regrading and repaving the affected area is the fix. On new construction, confirm the as-built slope matches the design.

Signage Requirements

Each accessible stall needs a vertical sign with the International Symbol of Accessibility, mounted at least 60 inches from the ground to the bottom of the sign and visible when a vehicle is parked. Van stalls add a "Van Accessible" plate. Oregon requires a supplemental sign stating the fine for unauthorized parking — an Oregon-specific detail that out-of-area installers often miss. Our ADA parking sign placement guide details heights, plates, and the fine sign.

Surface and Maintenance

Compliance extends to ongoing surface condition. The accessible stall, aisle, and route must stay firm, stable, and slip-resistant, with no abrupt level changes over a quarter inch, no cracks wider than half an inch, no potholes, and no ponding water. The Rogue Valley's hot, dry summers and cold winters create UV and freeze-thaw stress that fade and crack pavement over time. Prioritize accessible areas in seasonal maintenance and address trip hazards promptly.

When Repaving Triggers Upgrades

Routine maintenance — sealcoating, crack filling, patching, restriping existing markings — does not trigger ADA upgrades. A full repave, significant reconstruction, lot expansion, or regrading counts as an "alteration," obligating you to make the path of travel accessible and spend up to 20 percent of the project cost on accessibility where the existing route is not compliant. With Phoenix's ongoing rebuilding and development, many local projects already trigger this rule — build accessibility into the scope from the start.

Getting Phoenix Lots Compliant

The efficient path is an audit followed by remediation: the audit measures every accessible element and produces a fix list, and remediation handles the restriping, signs, and grading.
