I know we have discussed this before...Does a deadbolt with no other hardware meet the "one operation" unlatching requirement for egress on the thumbturn side (and we can debate accessibility)? And would you still label per 1008.1.8.3 (or whatever it is in newer codes (this door to remain....))...Thanks!

 
From ICC A117.1 - 2009

404.2.6 Door Hardware. Handles, pulls, latches, locks, and other operable parts on accessible doors shall have a shape that is easy to grasp with one hand and does not require tight grasping, pinching, or twisting of the wrist to operate. Operable parts of such hardware shall be 34 inches (865 mm) minimum and 48 inches (1220 mm) maximum above the floor. Where sliding doors are in the fully open position, operating hardware shall be exposed and usable from both sides.

EXCEPTION: Locks used only for security purposes and not used for normal operation shall not be required to comply with Section 404.2.6.
 
No... does not meet code - nor does it meet accessibility -

In buildings in occupancy Group A having an occupant load of 300 or less, Groups B, F, M and S, and in places of religious worship, the main exterior door or doors are permitted to be equipped with key-operated locking devices from the egress side provided: 2.1. The locking device is readily distinguishable as locked; 2.2. A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN BUILDING IS OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background; and 2.3. The use of the key-operated locking device is revokable by the building official for due cause. 3. Where egress doors are used in pairs, approved automatic flush bolts shall be permitted to be used, provided that the door leaf having the automatic flush bolts has no doorknob or surface-mounted hardware. 4. Doors from individual dwelling or sleeping units of Group R occupancies having an occupant load of 10 or less are permitted to be equipped with a night latch, dead bolt or security chain, provided such devices are openable from the inside without the use of a key or tool. 5. Fire doors after the minimum elevated temperature has disabled the unlatching mechanism in accordance with listed fire door test procedures. Hit list -

If residential in nature -

does not meet items 2.1, 2.2 and item # 4
 
BB it is actually an exterior "balcony" so egress is from the outside...It is in a cafeteria in a assisted living complex, so I could call it A <300, the thumb turn could be accessible (I don't think the one installed was).
