Curb painting is one of the most visible and most misunderstood elements of parking lot and property management. Every curb color communicates a specific parking rule, and those rules are backed by local and state codes. Incorrect curb painting creates confusion for drivers, exposes property owners to liability, and can result in fire code violations.
For Oregon commercial property managers, understanding curb color codes is essential for maintaining compliance and keeping your lot organized. This guide covers every standard curb color, what it means, when it is required, and how Oregon regulations apply.
While specific enforcement varies by municipality, Oregon follows the widely adopted curb color system used across the western United States.
Red is the most critical curb color. It designates fire lanes and absolute no-parking zones.
What it means:
Oregon requirements:
Common locations:
Maintenance note: Red curb paint fades faster than most property managers expect, especially in Oregon's UV-and-rain cycle. Faded red curbs lose their enforceability. Plan on repainting red curbs annually or at every restriping cycle.
Yellow curb marks areas designated for loading and unloading only, typically with a time restriction.
What it means:
Oregon context:
Common locations:
Blue curb marks areas associated with ADA accessible parking and access aisles.
What it means:
Oregon requirements:
Common locations:
White curb designates areas for short-term passenger loading and unloading only.
What it means:
Common locations:
Oregon note: White curb is less commonly enforced on private commercial properties but is standard on public streets near schools and transit facilities. Some Oregon municipalities use white curb interchangeably with designated passenger zones.
Green curb indicates parking with a limited time restriction, typically 10-30 minutes.
What it means:
Common locations:
Oregon note: Green curb is less common in Oregon than in California and other western states, but some Oregon municipalities and private property managers use it to manage high-demand short-term parking areas.
On private commercial property, property owners have broad authority to designate curb colors and parking rules. However, certain markings are regulated regardless of property ownership:
Oregon law requires that no vehicle park within 15 feet of a fire hydrant. Curb painting red within this zone is standard practice and should be maintained even when the lot is repainted.
Private property owners can enforce curb zone violations through towing, but must comply with Oregon's towing notification requirements under ORS 98.810-98.818. Proper signage must be posted indicating towing rules before vehicles can be removed.

Curb paint is typically the same traffic paint used for line striping:
Curb paint adheres best to clean, dry concrete or asphalt curb surfaces. Pressure washing before painting removes dirt, moss, and old loose paint. In Oregon, moss buildup on curbs is a common issue that must be addressed before repainting.
Curb paint fades faster than pavement striping because curbs are vertical surfaces exposed to direct weather. Plan on repainting curbs at least as often as you restripe the lot surface. High-visibility areas like fire lanes and ADA zones may need annual touch-ups.
