What This Guide Covers and Who It Helps
A tenant suite entry door is one of the most specified openings in commercial construction, yet it is also one of the most frequently under-specified. Whether you are a commercial sub bidding a multi-tenant office build-out, a facility manager reviewing a lease renovation, or an architect writing the hardware schedule for a Class A office floor, this guide walks through every hardware decision that affects function, security, code compliance, and long-term operability at a typical corridor-to-suite entry.
What Is a Tenant Entry Opening?
A tenant entry opening is the door assembly separating a shared egress corridor from a private office suite. It is typically a single hollow metal or wood door in a hollow metal frame, swinging into the tenant space (inswing), and serving a mixed audience: employees entering with credentials, visitors who need to be buzzed in, delivery personnel, and emergency responders. That mix of traffic patterns is exactly why getting the hardware right matters more than most subcontractors realize.
The Core Hardware Set: What the Opening Actually Needs
Lockset Function
The most common spec error on a tenant entry is applying a passage or classroom function when the opening genuinely requires a storeroom or office function. Here is how to think through it:
- Storeroom function: Outside lever always locked, keyed entry only. Good for suites where all employees have a key or credential and no walk-in public traffic is expected. Works well in professional office, legal, financial, and medical practice settings.
- Office function: Outside lever locked or unlocked by key or thumbturn from inside. Useful when reception staff needs to lock or unlock at will without going to the door.
- Electrified storeroom or mortise equivalent: Outside lever electrically released by card reader, keypad, or intercom. The go-to choice for access-controlled suite entries in multi-tenant office buildings and tech or professional campuses.
A Grade 1 mortise lockset is the right platform for a busy commercial tenant entry. It offers a durable latchbolt and deadbolt in a single chassis, accepts a wide range of cylinder and trim options, and accommodates electrified functions without a separate electric strike in most cases. Preferred lines such as Sargent, Corbin Russwin, and Hager offer robust mortise platforms with long parts-availability histories, which matters when a tenant renews a five-year lease and needs a cylinder re-keyed, not a full lockset replacement.
Cylinder and Key Control
Tenant entry cylinders almost always live inside the building master key system. At minimum, the cylinder should be keyed to the tenant sub-master so the property manager retains a grand master override without access to individual suite keys. Restricted keyways add a layer of duplication control that many Class A office landlords now require as a lease condition. Confirm the keyway family with the building's key system before specifying.
Door Closer
A door closer is required on any tenant entry that opens onto a rated corridor, and it is good practice even when no fire rating exists. Key considerations:
- ADA limits door-opening force to 5 lbs. on interior non-fire-rated doors. A properly adjusted ANSI size 1 through 3 closer on a standard 3-0 door can meet this without sacrificing positive latching.
- Regular spring adjustment is needed after HVAC recommissioning or seasonal pressure changes in high-rise buildings.
- For heavy-traffic suites, specify a closer rated for Grade 1 and backed by a solid warranty. Norton, Hager, and PDQ closers are dependable options available through DoorwaysPlus with stable parts support.
- Parallel arm mounting is sometimes required when door swing clearance is tight; confirm the mounting type before the frame goes in.
Hinges
A standard 3-hinge set of full-mortise ball-bearing hinges handles most tenant entry applications. Specify NRP (non-removable pin) hinges on the pull side when the hinge barrel is exposed to the corridor, which is common on inswing doors. Preferred hinge sources at DoorwaysPlus include Hager, McKinney, Rockwood, and ABH Manufacturing for consistent availability and finish matching.
Electrified Access Control Hardware
Access-controlled tenant entries are increasingly the default in office buildings built or renovated after 2010. The typical configuration:
- Card reader or mobile credential reader on the corridor (secured) side
- Request-to-exit (REX) sensor or push button on the suite (free egress) side
- Fail-safe or fail-secure electrified lockset or electric strike, depending on egress and life safety requirements
- Door position switch for the access control panel
The choice between fail-safe and fail-secure is a code and occupancy question, not a preference. If the suite entry is the only means of egress and the occupancy load triggers egress requirements, a fail-safe configuration is typically required so the door unlocks on power loss. Confirm with the authority having jurisdiction (AHJ) and the building's fire alarm sequence before finalizing the wiring mode.
Power transfer from frame to door for electrified locksets is an often-overlooked coordination item. Electrified hinges, door loops, and power transfers all serve this function; the right choice depends on the lockset manufacturer and door prep. Plan this before the frame is ordered.
Threshold and Bottom Seal
Many tenant entry doors see corridor foot traffic that creates noise transmission and air movement problems. A low-profile ADA-compliant threshold paired with a door bottom seal or sweep addresses both. The threshold height must not exceed 1/2 inch at corridor-to-suite transitions, with a maximum 1/4-inch vertical rise. Pemko thresholds and door bottoms are a well-proven option for tenant entries with high foot traffic.
Code and Compliance Touchpoints
- ADA / 2010 Standards: Lever handles, compliant opening force, proper threshold height, and accessible hardware mounting heights (34-48 inches AFF) are all required.
- IBC egress: The opening must provide free egress from the tenant side. Electric locks must release on activation of door-side hardware, loss of power, or fire alarm signal, depending on the code edition and occupancy.
- Fire rating: If the corridor is rated, the door assembly may need to be rated as well. Fire-rated assemblies require listed hardware throughout, including listed closers and fire-rated cylinders. Do not add non-listed hardware to a labeled door.
Putting the Hardware Set Together
A complete hardware set for a typical non-rated single tenant entry in a Class B or Class A office building commonly includes: mortise lockset (storeroom or office function), Grade 1 closer, three NRP ball-bearing hinges, wall or floor stop, door position switch, and threshold with door bottom seal. Electrified build-outs add an electric trim or electrified mortise, card reader, REX device, and power transfer device.
DoorwaysPlus carries preferred-brand options across all of these categories. Whether you need to spec the full set for a new build-out or source a replacement lockset for an existing tenant space, the team can help you match product, finish, and function to what the opening actually demands.
