Facility Overview

The One Main Place Parking Garage (managed by Ace Parking) is a secure, multi-level underground parking facility located directly beneath the prominent 20-story One Main Place commercial tower at 101 SW Main Street in Downtown Portland. Positioned in the heart of the central business district along the western banks of the Willamette River, this well-maintained structure provides sheltered, weather-protected parking for tenants, business visitors, and waterfront sightseers alike. The garage layout features clearly delineated one-way driving aisles, easy-to-read directional signage, and smooth concrete ramps connecting tiers. The facility comfortably accommodates standard passenger sedans, compact crossovers, and mid-size SUVs. Drivers of full-size pickup trucks, customized high-profile SUVs, or conversion vans should note the posted garage maximum clearance height of 6 feet 6 inches (1.98 m), while commercial box trucks and vehicles carrying rooftop cargo boxes are advised to seek surface lot parking options nearby.

Visitor & Driver Tips

Because SW Main Street and SW 2nd Avenue are one-way thoroughfares, program your navigation system directly to the SW 2nd Avenue entrance to avoid unnecessary detours around city blocks. During peak morning commute hours (7:30 AM to 9:00 AM) and evening rush hours (4:30 PM to 6:00 PM), allow an extra 5 to 10 minutes to navigate garage entry gates and exit lanes. If visiting for major events at Tom McCall Waterfront Park or weekend festivities, arrive early as nearby parking garages tend to fill quickly. Always ensure personal belongings are removed or concealed in your trunk before leaving your vehicle.
