Door hardware on multifamily projects is a specification detail that receives less attention than cabinet hardware, countertop selection, or flooring product, yet it is a component residents interact with every time they enter or leave a room. Hardware that fails within a year of move-in generates maintenance calls and resident dissatisfaction. Hardware that looks inconsistent across unit types within the same building generates complaints from both residents and developers at the first walkthrough.
Understanding the grading system for door hardware, the appropriate grades for different applications within a multifamily project, and the coordination requirements between door hardware and the broader hardware finish package allows GCs to confirm that the specification is correct before procurement begins.
ANSI/BHMA grading for residential hardware
The American National Standards Institute and the Builders Hardware Manufacturers Association publish grading standards for door hardware that classify products by cycle testing, force requirements, and durability. For multifamily residential applications, three grades are relevant.
Grade 1. The highest cycle rating, tested to 250,000 or more cycles. Grade 1 hardware is specified for commercial applications and for high-traffic residential applications. In multifamily construction, Grade 1 hardware is appropriate for main entry doors to the building, for mail room and amenity space doors, and for any door in a common area that will experience heavy daily use.
Grade 2. Tested to 400,000 cycles in some classifications. Grade 2 hardware is appropriate for residential unit entry doors and for interior unit doors that experience moderate daily use. Most Class A and Class B multifamily residential unit hardware is specified at Grade 2.
Grade 3. The entry-level residential grade, tested to 150,000 cycles. Grade 3 hardware is appropriate for interior unit doors in applications where the hardware will not experience heavy use. Closet door hardware and seldom-used interior room hardware are appropriate Grade 3 applications.
For workforce and affordable housing where long-term durability is a priority over the forty-year life of a LIHTC property, specifying Grade 2 hardware throughout rather than Grade 3 for interior doors adds a small per-unit cost but significantly extends the replacement cycle.
ADA lever hardware requirements in accessible units
ADA Standards for Accessible Design require that door hardware in accessible units and in accessible common areas be operable with one hand without tight grasping, pinching, or twisting of the wrist. Lever handles meet this requirement. Round knobs do not. In accessible units and in accessible common area doors, lever hardware is required throughout.
In active adult communities where universal design is the specification intent, lever hardware should be specified throughout every unit, not limited to designated accessible units. Confirm with the developer whether the project’s design intent calls for lever hardware throughout all units or only in designated accessible units.
Finish coordination across divisions
Door hardware finish must coordinate with cabinet hardware finish (Division 6 cabinet pulls), toilet accessory finish (Division 10), and plumbing fixture trim finish (Division 22). On Class A multifamily projects, the hardware finish package covers all three scopes as a unified selection. Satin nickel, matte black, brushed gold, and polished chrome are the most common finish packages in western US Class A multifamily.
The door hardware finish is specified in the Division 6 scope alongside cabinet hardware. Confirm with the Division 6 sub that the door hardware finish specification they have received matches the hardware finish specification that Division 10 and Division 22 subs are working from. A mismatch discovered at installation cannot be corrected without returning and reordering hardware, which creates a schedule delay.
Keying and master key systems
Multifamily residential buildings require a master key system that allows property management access to all units with a single key while providing residents with individual unit key control. The hardware sub must coordinate with the property manager on the master key system specification before door hardware is ordered, because the key control system determines which lockset cylinders are compatible with the master key.
Rekeyable locks, which allow the property manager to rekey individual units between tenancies without replacing the lockset, are increasingly specified on multifamily projects to reduce key management costs over the life of the building. Confirm whether the project specifies rekeyable locks and ensure that the hardware sub’s product selection is compatible with the specified rekeyable system.
Common area door hardware
Common area doors in multifamily buildings, including building entry doors, corridor doors to amenity spaces, and stairwell doors, require commercial-grade hardware appropriate for heavy daily use. Building entry doors with keypad or fob access control typically require hardware that integrates with the access control system. Confirm that the Division 6 sub’s hardware selection for building entry doors is compatible with the access control system being installed.
Stairwell and corridor doors in multifamily buildings are typically fire-rated assemblies with specific hardware requirements for fire door certification. The hardware on a fire-rated door assembly must be listed by an approved listing organization and installed according to the door assembly listing requirements. Confirm that the hardware sub understands fire door hardware requirements before assigning fire-rated door hardware scope.
How Innergy specifies door hardware
On Innergy projects, door hardware is specified in the Division 6 submittal organized by application: unit entry doors, interior unit doors, closet doors, and common area doors. We confirm the finish specification against Division 10 and Division 22 hardware packages. We coordinate with the property manager on the master key system before hardware procurement. For Division 6 door hardware as part of a full seven-division package in TX, WA, OR, CO, UT, or NM, contact us and we respond within one business day.
Procurement timing for door hardware
Door hardware for residential unit entry doors is installed late in the construction sequence, after paint and often after flooring. However, the hardware must be procured earlier in the project because delivery lead times for Grade 2 hardware in specific finishes can run two to four weeks from standard distributors and longer for specialty finishes.
Confirm the procurement timeline with the Division 6 sub at pre-construction and confirm that hardware orders are placed in time to arrive at the project before the installation sequence begins for the affected floors. Hardware that arrives after the installation crew has already moved through those floors creates a return trip that adds cost to the project.
