Division 10 is the most logistically complex interior finishes scope in multifamily construction. Toilet accessories, 4C mailboxes, ADA signage, toilet partitions, fire extinguisher cabinets, Knox boxes, and wire shelving are seven distinct product categories with seven different procurement lead times, seven different installation sequences, and seven different coordination requirements with other trades, third parties, and inspection authorities.
On a multifamily project in Oregon, Division 10 also carries specific compliance requirements that are stricter than what applies in some other western states. ADA signage requirements apply to all publicly accessible spaces. The USPS 4C mailbox approval process must be completed before mail delivery service begins. Knox box locations must be approved by the local fire authority. Portland’s permitting environment and the CCB licensing requirements that apply statewide add additional process overhead to projects that require a Division 10 sub who is organized enough to manage it without defaulting coordination responsibilities to the superintendent.
What Division 10 covers on a multifamily project
The full Division 10 scope on a multifamily project includes:
Toilet accessories : toilet paper holders, towel bars, grab bars, soap dispensers, robe hooks, and shower accessories. Installed per the unit type matrix for residential units and per ADA requirements for common area restrooms. Grab bar blocking must be in the wall before drywall closes. This is a pre-construction coordination item, not an installation-day item.
Toilet partitions : for projects with common area restrooms in leasing offices, fitness centers, or commercial ground floors. Powder-coated steel, solid plastic, and phenolic options, selected based on the use intensity and humidity conditions of the space. Ceiling-hung, floor-mounted, and floor-to-ceiling configurations.
ADA signage : room identification, directional, and informational signage in all publicly accessible spaces.ible spaces. Oregon projects must meet ADA Standards for Accessible Design requirements for character height, raised lettering, Grade II Braille, and non-glare finish. Permit-set specifications must be followed. Mounting heights must be confirmed against architectural drawings, not assumed from a standard template.
4C mailboxes : USPS-approved horizontal mailbox systems. Rough opening dimensions confirmed with the GC before framing. Parcel locker count confirmed against the unit count. USPS approval process initiated early enough to complete before occupancy.
Fire extinguisher cabinets : recessed, semi-recessed, or surface-mounted, as specified. Recess depth confirmed against wall construction before framing advances. Cabinet type confirmed against the specification before procurement.
Knox boxes : location approved by the local fire authority before installation. In Portland, Knox box location approval goes through Portland Fire and Rescue and must be completed before the certificate of occupancy is issued.
Wire shelving : ventilated wire shelving for pantry, linen, and utility closets per unit plans. Wall anchor type confirmed against wall construction before installation.
What Oregon GCs should confirm about a Division 10 sub
Pre-construction coordination on blocking. Grab bar blocking locations must be in the wall before drywall closes. If the Division 10 sub does not provide blocking specifications to the GC at pre-construction, the GC has to assume standard locations and hope they match what the sub will need. A qualified Division 10 sub provides blocking specifications, heights, locations, and load requirements, before framing advances on the relevant walls.
4C mailbox procurement timeline. The USPS 4C approval process takes four to six weeks from initiation to approved delivery service. If the Division 10 sub does not initiate the approval process with enough lead time before projected occupancy, residents move into a building without mail service. Ask the sub when they plan to initiate the approval process and what they need from the owner or property manager to start it.
Knox box coordination. In Portland and other Oregon jurisdictions, Knox box location must be approved by the fire authority before installation. If the Division 10 sub treats the Knox box as a routine installation item without confirming the location approval, the box may be in the wrong location, which creates a correction that costs time and money. Confirm that the sub’s process includes fire authority coordination before any work is done.
ADA signage compliance documentation. Oregon projects in publicly accessible spaces require ADA-compliant signage. Ask the Division 10 sub to provide a submittal that includes the specific signage product, its compliance with ADA character height and Braille requirements, and the mounting height plan for each sign type. A submittal that simply says “ADA compliant signage” without product specifications and mounting height documentation is not a submittal.
CCB licensing. Oregon requires CCB licensing for contractors performing installation work. Confirm that the Division 10 sub holds an active Oregon CCB license and that the license covers the installation work they are performing on your project.
The sequencing problem Division 10 creates without a coordinated sub
Division 10 accessories in residential units are the last interior finishes installation in the sequence. They go in after paint, after flooring, and after cabinet installation is complete. If the Division 10 sub shows up to a unit where any of those predecessor trades are not finished, they either have to delay installation or risk damaging the completed work.
If the Division 10 sub is a separate subcontract from the flooring and cabinet subs, coordinating that final installation visit is the superintendent’s problem. The superintendent has to confirm that all three predecessor trades are complete on a specific floor, notify the Division 10 sub, and manage the scheduling if any of the predecessor trades is not ready.
If the Division 10 sub is the same company as the flooring and cabinet sub, as is the case when you use Innergy, the sequencing is managed internally. We know when our own flooring and cabinet crews have finished a floor because we are running those crews. We schedule our accessories installation behind our own work without requiring the superintendent to coordinate the handoff.
Innergy’s Division 10 scope in Oregon
Innergy covers the full Division 10 scope on Oregon multifamily and commercial projects as part of our seven-division interior finishes package. We provide blocking specifications to the GC before framing advances on relevant walls. We initiate the 4C mailbox USPS approval process on your project timeline, not on ours. We coordinate Knox box location approval with the local fire authority before installation. We submit ADA signage product data for review before procurement.
For Oregon GCs who want Division 10 as a standalone scope or as part of a complete seven-division interior finishes package, contact us and we will respond within one business day.
