Speed Bump Installation in Portland, Oregon: Cojo's 2026 Service Guide

Cojo installs speed bumps in Portland, Oregon parking lots and private community roads. Our crews work out of a Willamette Valley base and we run jobs across the whole metro. If your install touches public right-of-way, you're looking at City of Portland Title 17 (Public Improvements) and Title 33.266 (Off-Street Parking and Loading), plus Portland Bureau of Transportation (PBOT) traffic-calming standards. Private parking-lot work skips the city permit, but you still have to keep ADA-accessible routes clear and preserve fire-apparatus access per IFC 503.
Below: the Portland regulatory side, the neighborhoods we serve, three jobs we've actually run, and how to get on our quote schedule.
There are three layers to think about:
For a speed bump installed entirely on private parking-lot property -- past the right-of-way line -- the City of Portland does not require a permit. The owner or property manager directs the installation. Cojo's process verifies that:
Portland public-street speed humps (not bumps -- Portland uses humps, not bumps, on city streets) require a neighborhood petition, a PBOT engineering review, and inclusion in PBOT's traffic-calming program. The process and eligibility criteria are administered by PBOT.
If a property owner has a private drive aisle that connects to a Portland public street and wants a bump installed within the connecting throat, Title 17 may apply because the throat is partially in city right-of-way. Cojo coordinates with PBOT staff in those cases.
Portland's land-use code at Title 33.266 requires off-street parking facilities to comply with federal ADA standards. A bump that blocks an accessible route from parking to a building entrance is a violation, regardless of whether the city issues a permit or not.
Cojo provides speed-bump installation across the Portland metro service area, including but not limited to:
For installs in surrounding cities, see Cojo's pages for Beaverton, Hillsboro, and Gresham.
A 22,000-square-foot mixed-use retail-and-office center on NW 13th. Existing parking lot had no speed control on the main drive aisle, and the property manager documented two near-miss incidents involving customers crossing between cars and a delivery truck. Cojo installed three 8-foot recycled-rubber bumps, 3.5 inches tall, with pre-molded chevron and reflective tape. Total install: 6 crew-hours, conducted on a Sunday morning to minimize tenant disruption.
A 96-unit apartment complex on NE Sandy near 42nd. Tenants had submitted complaints about over-speed traffic on the long main drive aisle and the property had received an insurance-renewal request for engineered traffic-calming. Cojo installed three 8-foot rubber bumps, 3 inches tall, plus MUTCD W17-1 advance signage. ORS 90.322 tenant notice was issued 7 days before the install.
A 35,000-square-foot light-industrial annex serving a Gateway-area distribution operation. The site had OSHA-driven speed-control needs in the truck yard. Cojo installed five heavy-duty rubber bumps, 3 inches tall, with 8-anchor-per-section forklift-rated hardware. Reference: see speed bumps for warehouses for the full warehouse-grade specification.
Industry Baseline Range for Portland speed-bump installation:
| Item | Industry Baseline Range |
|---|---|
| Rubber bump (single 6 to 8-ft section, installed) | $350 to $900+ |
| Asphalt bump (cast-in-place, installed) | $400 to $1,500+ |
| Heavy-duty warehouse bump (forklift-rated) | $400 to $1,200+ |
| MUTCD signage per bump | $150 to $400 |
| Sunday or off-hours mobilization | $300 to $800 |
| Multi-bump install (3+ bumps, single mobilization) | 10 to 20 percent off list |
2026 Portland-metro install pricing reflects Oregon prevailing-wage requirements on commercial sites above $25,000 in scope, elevated rubber-feedstock costs, and added documentation expectations from Portland-area property-insurance underwriters. Off-hours mobilization is the new standard for installs at sites with significant tenant or customer traffic.
