A medical office building (MOB) in Salem operates under the same ADA accessibility obligations as any healthcare facility nationwide. 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. Salem's MOB inventory spans the Salem Health campus corridor, the private MOB clusters near Liberty Road and Center Street NE, and the state-capital-adjacent clinics serving state-agency employee health plans. Cojo installs ADA-compliant curb ramps at Salem Marion County MOBs, and this guide explains how to scope the work so the project closes inside the after-hours window and patient-access continuity holds.
ADA 2010 Section 406, Field-Ready 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.
Cross-slope drift is the most common Salem MOB compliance failure, especially on ramps poured before 2010 when field verification was less consistent. A digital-level field measurement catches this before an ADA demand letter or patient complaint. See ADA curb ramp slope requirements for the field protocol and remediation options.
Salem MOB Operating Constraints
Patient-access continuity drives every Salem MOB ADA scope. The MOB cannot route patients away from accessible entrances during business hours; the contractor works after-hours or schedules around clinic-day-off windows (often Friday afternoons or full weekends). Salem Health's main campus and other 24/7 facilities carry an ambulance-access-lane constraint -- those lanes cannot be blocked for any extended window.
The state-capital adjacency adds another vetting layer for some MOBs that serve state-agency employee plans. Procurement and vendor agreements often require CCB license verification, current insurance certificates, and a written acknowledgment of patient-area access restrictions. Cojo carries the required coverage and handles vendor onboarding up front.
Marion County and City of Salem Permitting
City of Salem permitting for ADA curb ramp installation depends on the scope. A single-ramp replacement on an existing accessible route falls under a minor public-works permit. A multi-ramp project affecting pedestrian circulation patterns may trigger a site-development review. Salem Public Works and the Community Development Department coordinate on ramps interfacing with the public right-of-way.
For MOBs on hospital or healthcare-system property, the facility's ADA transition plan typically drives the scope. Salem Health and the larger private MOBs maintain field-measured ramp inventories that streamline 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
Salem MOB ADA scopes rarely land at baseline. After-hours premium labor, ambulance-access traffic-control, hidden sub-base conditions on older MOBs (especially the 1970s-and-1980s private MOB cluster near Center Street and Mission), and concrete-cure waits push the real number up. High-early-strength concrete mixes get the ramp back into service in 24 to 48 hours but add 15 to 30 percent to the concrete line item.
Phasing Around Clinic Operations
Most Salem MOBs operate Monday-through-Friday clinic hours with reduced weekend coverage. The cleanest phasing window is Friday evening through Sunday afternoon, with the ramp accepting foot traffic Monday morning. High-early-strength concrete mixes make this single-weekend window workable for individual ramps; multi-ramp projects phase across several weekends.
Cojo's concrete services handles the curb ramp installation, with related Salem parking lot striping for ADA accessible stall layout, accessible-aisle painting, and ADA signage post-install. The Oregon asphalt paving cost baseline covers parking-lot scopes that include both asphalt and concrete work.
What the Practice Manager and MOB Operations Lead Decide
The buyer at a Salem 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 inventory), schedule (single weekend or multi-weekend phasing), and concrete mix (standard cure or high-early-strength). For an active ADA complaint or demand letter, the high-early-strength mix wins on the schedule lever even at the premium.
For MOBs that are part of a broader 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 Salem 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 of settlement on Willamette Valley clay subgrade. The second is detectable-warning panels that have lifted, cracked, or worn through. The third is flare-slope drift at the side transitions, which creates a tripping hazard at the curb-flare interface.
Catching these failures 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. Salem MOB facility managers who run their ADA transition-plan refreshes on a 5-to-7-year cadence typically find 3 to 8 ramps in this combined failure pattern at each refresh -- enough volume to make a single multi-ramp mobilization the most cost-effective approach. The state-capital-corridor MOB cluster also tends to have a tighter compliance-audit cadence than other Oregon markets because some MOBs serve state-agency employee plans that audit ADA compliance as part of vendor agreements.

Every Salem 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 Marion County from the Salem Health corridor to the Liberty Road MOB cluster to state-capital-adjacent clinics.
