Parking Signs for Office Parks: Tenant + Visitor + ADA Mix

A multi-tenant office park has a parking management problem that single-tenant buildings do not. Five tenants with five different head-counts, three different visitor patterns, and one shared ADA pool create constant low-grade conflict in the lot. The wrong sign system makes the property manager the referee on every dispute. The right sign system makes the parking allocation legible to every employee and visitor without anyone having to ask.
Below is the sign package we run at Oregon multi-tenant office parks, with the federal, state, and city code references each sign maps to.
Office park parking signs span five categories: tenant-assigned parking, visitor and guest parking, ADA accessible (R7-8 and R7-8a), EV charging (R10-21), and shared service signage (fire lanes, loading zones, accessible routes). The 2010 ADA Standards for Accessible Design control accessible stall counts under Section 208, and ORS 98.812 governs the tow-away language for tenant-only enforcement. A 200-stall office park typically needs 35 to 55 signs covering these zones.
Three allocation models, three different sign packages:
Each model carries different signage. Pro-rata uses tenant-name signs (must be updated on every lease change). Permit allocation uses generic "PERMIT REQUIRED" signs (more durable, supports tenant turnover without sign change). First-come-first-served uses time-restricted signs (most flexible, lowest enforcement).
We default to the permit allocation model on multi-tenant builds because it survives lease changes without a sign refresh.
Visitor parking at an office park has three failure modes:
The bundle that prevents all three:
The overnight prohibition sign is the most-skipped element of the bundle and the one that most often breaks an office park's tenant relations. Without it, visiting traveling consultants park overnight, take tenant-assigned stalls in the morning, and trigger the dispute that the property manager has to mediate.
ADA Standard 208.2 sets the minimum stall count by parking lot size. For typical office parks:
| Lot Size | Required Accessible Stalls | Van-Accessible |
|---|---|---|
| 26 to 50 stalls | 2 | 1 of 2 |
| 51 to 75 stalls | 3 | 1 of 3 |
| 76 to 100 stalls | 4 | 1 of 4 |
| 101 to 150 stalls | 5 | 1 of 5 |
| 151 to 200 stalls | 6 | 1 of 6 |
| 201 to 300 stalls | 7 | 2 of 7 |
Multi-tenant office parks add a complication: the ADA stalls are a shared resource across all tenants. A tenant cannot reserve an ADA stall for their own employees. If a tenant has a high need (a tenant whose business serves people with disabilities, for example), the property manager can create additional non-ADA reserved stalls near the entrance, but cannot privatize the ADA stalls themselves.
For new construction and major remodels, yes. Oregon's HB 2180 (2023) sets EV stall minimums for new commercial parking, and several municipalities (Portland, Beaverton, Hillsboro) layer additional requirements through their development codes.
EV stall signage uses the MUTCD R10-21 series (added in the 2023 supplement), with green-on-white sheeting and the EV plug pictogram. To make the EV-only restriction enforceable in Oregon, pair the R10-21 with an ORS 98.812 tow-away addendum.
The MUTCD is published by the Federal Highway Administration at mutcd.fhwa.dot.gov.
A 5-building office park in Hillsboro called us in March 2026 to refresh the parking sign system after a tenant churn left the previous tenant-name signs out of date. The property had:
Our scope:
Total install ran in the $14,500 to $19,000 range across two weekends, consistent with the Industry Baseline Range for a 71-sign office park refresh.
| Component | Cost |
|---|---|
| Tenant-permit allocation sign | $175 to $325 |
| Visitor stall sign with tow-away addendum | $200 to $375 |
| ADA R7-8 / R7-8a pair on new post | $250 to $500 |
| EV stall sign (R10-21 + tow plate) | $200 to $400 |
| Wayfinding sign at campus entry | $300 to $650 |
| Full office park sign refresh (60 to 80 signs) | $14,000 to $22,000 |
Aluminum sign blanks rose 11 percent across 2025, custom-printed tenant-name signs carry 4 to 6 week lead times, and EV signage stock is intermittently constrained by green-sheeting supply. Office park managers planning a 2026 sign refresh should budget 20 to 30 percent above 2023 install pricing and order tenant-name custom prints 8 weeks ahead of the install.
A defensible office park sign install gives the manager:
The sixth item is the one most often missed. A perfect sign install with no tenant communication produces a wave of confused calls to the property management office on day one.
Q: Can a tenant in a multi-tenant office park reserve an ADA stall for their own employees?
A: No. ADA Standard 208 makes accessible stalls a shared building-wide resource. A tenant cannot privatize an ADA stall. If a tenant has a documented need for additional reserved stalls near the entrance, the property manager can create non-ADA reserved stalls separately, but the ADA stall pool must remain open to any person with a valid placard or plate.
Q: What's the most defensible tenant parking sign wording at a multi-tenant office park?
A: "AUTHORIZED VEHICLES ONLY - PERMIT REQUIRED - VIOLATORS TOWED AT OWNER'S EXPENSE - ORS 98.812" with the towing company's name and phone number. This wording supports a permit allocation system, gives the property manager flexibility on enforcement, and survives tenant turnover without a sign change.
Q: Are EV charging stalls required at office parks in Oregon?
A: For new construction and major remodels, EV stall minimums apply under HB 2180 (2023) and most Oregon municipal development codes. Existing office parks are not retrofit-required, but Oregon DEQ and EV-incentive programs commonly fund retrofits for properties that voluntarily add stalls. Sign with R10-21 and an ORS 98.812 tow-away plate.
Q: How tall does a tenant-name sign need to be?
A: There is no federal or Oregon minimum height for tenant-name signs as a category. We default to a 12 inch by 18 inch sign with the tenant name in 2-inch letters and the stall range in 1-inch letters, matching the standard reserved parking sign dimensions. The bottom of the sign should be at least 60 inches above the surface for sight-line readability.
Q: How often should office park parking signs be refreshed?
A: Every 5 to 7 years for material refresh, with mid-cycle updates for tenant changes. The bigger driver is tenant churn: a major lease change typically prompts a tenant-name sign refresh and an audit of the stall allocation. Annual visual inspection is the minimum for fade, vandalism, and vehicle-strike damage.
