A medical office building (MOB) in Eugene has the same ADA accessibility obligation as any other healthcare facility in the country. The 2010 ADA Standards for Accessible Design, Section 406, set the slope, width, landing, and detectable-warning requirements for every curb ramp on an accessible route. The Eugene MOB inventory ranges from the PeaceHealth RiverBend campus on the Springfield border through the private MOB cluster along Hilyard Street and the West 11th medical district. Cojo installs ADA-compliant curb ramps at Eugene Lane County MOBs, and this guide explains how to scope the work so the project closes inside the patient-access-continuity window.
ADA 2010 Section 406, the Practical Version
Section 406 sets a running slope of 1:12 maximum (8.33 percent), a cross slope of 1:48 maximum (2.08 percent), a ramp width of 36 inches minimum, and a level landing at the top of the ramp at least 36 by 36 inches. Flare slopes on the sides of a ramp where they transition to the adjacent walking surface are limited to 1:10 (10 percent) maximum. Detectable warning surfaces (truncated domes) are required at the bottom of every ramp where it meets a vehicular route -- they extend the full width of the ramp and 24 inches deep in the direction of travel.
The most common Eugene MOB compliance failure is the cross slope drifting above 2.08 percent on ramps installed before 2010, when the cross-slope discipline was less consistently field-verified. A digital-level field measurement catches this before the ADA demand letter. The ADA curb ramp slope requirements reference page covers the field measurement protocol and what to do when an existing ramp fails.
Eugene MOB Operating Constraints
Patient-access continuity drives every Eugene MOB ADA scope. The MOB cannot detour patients away from accessible entrances during business hours; the contractor has to work after-hours or schedule around clinic-day-off windows. PeaceHealth RiverBend's 24/7 emergency operations carry an additional constraint on any ramp affecting ambulance-access lanes -- those cannot be blocked for any extended window.
Lane County HIPAA-adjacent vendor vetting also applies. The MOB facility manager will ask for insurance certificates, CCB license verification, and sometimes a vendor agreement that acknowledges patient-area access restrictions. Cojo carries the required coverage and handles vendor vetting up front.
Lane County and City of Eugene Permitting
City of Eugene permitting for ADA curb ramp installation depends on scope. A single-ramp replacement on an existing accessible route generally falls under a minor public-works permit. A multi-ramp project that affects pedestrian circulation patterns may trigger a site-development review. Eugene Public Works and the Building Permit Services office coordinate on ramps that interface with the public right-of-way.
For MOBs on a hospital or healthcare-system property, the facility's ADA transition plan usually drives the scope. PeaceHealth's RiverBend campus and other major Eugene health systems maintain field-measured ramp inventories that streamline the bid-document preparation.
Industry Baseline Range
| Project Type | Cost Per Ramp | Typical Project |
|---|---|---|
| Single ramp replacement (standard width) | $1,700 to $4,200 | $1,700 to $4,200 |
| Multi-ramp replacement (5 to 10 ramps) | $1,400 to $3,500 per ramp | $7,000 to $35,000+ |
| Ramp + adjacent sidewalk panel | $2,300 to $6,000 | $2,300 to $6,000 |
| Detectable warning retrofit (only) | $400 to $1,200 per panel | $400 to $12,000+ |
Current Market Reality
Eugene MOB ADA scopes rarely land at baseline. After-hours premium labor, traffic-control during ambulance-access lane work, hidden sub-base conditions under the existing ramp (especially on older MOBs around Hilyard Street and 18th Avenue), and concrete-cure waits all push the real number up. The cure-wait can add 5 to 10 days of patient-route detour management unless a high-early-strength concrete mix is specified.
Phasing Around Clinic Operations
Most Eugene MOBs run clinic hours Monday through Friday with reduced weekend coverage. The cleanest phasing window is Friday evening through Sunday afternoon, with the ramp accepting foot traffic by Monday morning. High-early-strength concrete mixes make this window workable for single-ramp replacements; multi-ramp projects phase across several weekends. PeaceHealth RiverBend's 24/7 operations need an even tighter window for ramps near emergency access, often confined to a 6-to-8-hour overnight pour with the ramp barricaded until cure.
Cojo's concrete services handles the ramp installation, and the related Eugene parking lot striping covers accessible stall layout, accessible-aisle painting, and ADA signage post-install. The Oregon asphalt paving cost baseline applies on parking-lot scopes that include both asphalt and concrete work.
What the Practice Manager and MOB Operations Lead Decide
The buyer at a Eugene MOB is usually the practice manager (single-tenant MOB) or the MOB operations lead (multi-tenant MOB). Three levers move cost: scope (single ramp, full inventory, or partial), schedule (single weekend or multi-weekend phasing), and concrete mix (standard cure or high-early-strength). For an active ADA complaint, the high-early-strength mix usually wins on the schedule lever despite the premium.
For MOBs that are part of a campus ADA upgrade, bundling the curb ramp work with parking-lot restripe per hospital and medical office striping discipline reduces mobilization overhead by 10 to 15 percent.
Common Failure Patterns Found at Site Walks
A site walk of an existing Eugene MOB accessible route usually surfaces three failure patterns. The first is cross-slope drift -- a ramp poured to 1:48 in 2008 may now read 1:40 or worse because frost or settlement has tilted the slab. The second is detectable-warning panels that have lifted, cracked, or worn through to the point where the truncated-dome surface no longer functions for cane-detection. The third is flare-slope drift, where the side flare has either eroded or compressed below the 1:10 maximum, which creates a tripping hazard at the curb-flare transition.
None of these failures is necessarily severe enough to trigger an immediate compliance complaint, but together they represent the typical scope a Eugene MOB walks into during an ADA transition-plan refresh. Catching them at the walk-through stage and addressing them in a single bundled scope reduces mobilization overhead and gets the campus current with the 2010 Standards in one capital event rather than three.

Every Eugene MOB curb ramp scope sits on its own combination of existing-condition compliance gap, patient-access constraint, and after-hours phasing window. The only way to land an accurate number is a site walk with field measurement of every ramp on the accessible route. Cojo is CCB licensed and insured and has installed ADA curb ramps at MOBs across Lane County from PeaceHealth-corridor MOBs to private clinics along Hilyard Street, West 11th, and Coburg Road.
