iv. ADA Standards (1) 404 Doors, Doorways, and Gates

3. Types of Doors : PP-28 through PP-40 a. Q1 : Is the door in the Means of Egress?

i. A1 : No = No egress requirements (1) Means of Egress = Exit Access + Exit + Exit Discharge

b. Q2 : Is the “door” pivoted or side-swinging? i. A2 : Yes = Must meet IBC 1008 & 1020.2 ii. A2 : No = Go to Q3

c. Q3 : Is it (1) of the (9) exceptions to 1008.1.2? i. Of the (9) exceptions, (6) may be applicable to what Flad does :

(1) Private garages, office areas, factory and storage areas with an occupant load of 10 or less.

(2) Critical or intensive care patient rooms within suites of health care facilities. (3) In other than Group H occupancies, revolving doors complying with Section

1008.1.4.1. (4) In other than Group H occupancies, horizontal sliding doors complying with

Section 1008.1.4.3 are permitted in a means of egress. (5) Power-operated doors in accordance with Section 1008.1.4.2. (6) In other than Group H occupancies, manually operated horizontal sliding doors

are permitted in a means of egress from spaces with an occupant load of 10 or less.

d. 1008.1.2 Door swing i. When determining door swing (OL>50), one cannot “assign” specific OLs to

individual doors. No “traffic cops” to direct egressing occupants B 49 + 50 occupants.

4. Size of Doors : PP-41 through PP-50 a. Minimum (Door)

i. Clear Width = 32” (1) Bed Movement = 41.5” (2) Openings more than 24” deep = 36”

ii. Clear Height = 80” b. Maximum (Door)

i. Door Leaf (Swinging) = 48” ii. Clear Hgt = No max

c. Width i. Clear Width : face of the door to the (hinge) stop, with the door open 90 degrees. ii. Occupant Load (OL) determination

(1) Rule of Thumb = limit door sizes between 36” – 48”


(2) Door multiplier (a) 0.2 inch per occupant (b) 0.15 inch per occupant (auto sprinkler system + emergency voice/alarm

communication system (c) Example : 36” door leaf

(i) 36” - Stop - Door Thickness – Tolerance (ii) 36” – 0.625” – 1.75” – 0.125” = 34.125” (iii) 34.125” x 0.15” per occupant = 227 occupants

d. Maximum Total Occupant Load (for building) i. Example 1 : (2) doors with 307+307 occupants

(1) Limited to 500 occupants because of the number (2) exits. ii. Example 2 : (2) doors with 227+307 occupants

(1) Limited to 454 (227+227) occupants because the occupant load (OL) is limited by the lesser (227 vs 307) capacity of the (2) exits.

5. Elevation & Arrangement : PP-51 through PP-59 a. Floor elevation on each side of a door must be within 1/2” b. Thresholds 1/4 to 1/2” max c. Door Arrangement : provide 48” between doors in a series

6. Maneuvering : PP-60 through PP-71 a. Clearances for accessibility = 60” circle or 60” T-shaped b. Door swings cannot swing into required Clear Floor Space for any fixture. c. Clearances at Doors

i. Approach Direction : From front/From hinge side/From latch side ii. Door Side : Push or Pull iii. Perpendicular vs Parallel iv. Distances based on :

(1) Reach ranges = 24” side, 12” forward (2) Clear floor space = 30”x48” (3) Turning Radius = 60”

9. In other than Group H occupancies, manually operated horizontal sliding doors are permitted in a means of egress from spaces with an occupant load of 10 or less.




Exceptions:1. Private garages, office areas, factory and storage areas with an occupant load of 10 or less.

(Examples : Overhead garage doors and/or horizontal sliding doors, both either manual or powered)

3. Critical or intensive care patient rooms within suites of health care facilities.(Horizontal sliding glass doors = limited egress need + equipment movement + nurse supervision)

9. In other than Group H occupancies, manually operated horizontal sliding doors are permitted in a means of egress from spaces with an occupant load of 10 or less. (Manual vs. power-operated)


Code Question (Actual)

Q : Can a “pass-thru door” within an overhead

garage door (coiling or sectional) be utilized as a

Means of Egress component?





Exceptions:

1. Private garages, office areas, factory and storage areas with an occupant load of 10 or less.


Except as specifically permitted by this section egress doors shall be readily openable

from the egress side without the use of a key or special knowledge or effort.

1008.1.9.2 Hardware height.

Door handles, pulls, latches, locks and other operating devices shall be installed 34

inches minimum and 48 inches maximum above the finished floor. Locks used only for

security purposes and not used for normal operation are permitted at any height.



A : It depends … if the pass-thru swing door is independent of the overhead coiling/sectional garage door, then it is acceptable.

If the pass-thru swing door is part of the overhead coiling/sectional garage door so that it moves vertically withthe garage door, it is not acceptable.


Acceptable Not Acceptable


Doors shall swing in the direction of egress

travel where serving a room or area containing

an occupant load of 50 or more persons or a

Group H occupancy.

5. Exterior decks, patios or balconies that are part of Type B dwelling units, have impervious surfaces and that are not more than 4 inches (102 mm) below the finished floor level of the adjacent interior space of the dwelling unit.

36” Minimum : Door

OR

44” Minimum : Stair

1008.1.7 Thresholds

Thresholds at doorways shall not exceed 3/4 inch in height for sliding doors serving dwelling units or 1/2 inch for other doors.

Raised thresholds and floor level changes greater than 1/4 inch at doorways shall be beveled with a slope not greater than one unit vertical in two units horizontal (50-percent slope).

Exception:

The threshold height shall be limited to 7-3/4 inches (197 mm) where the occupancy is Group R-2 or R-3; the door is an exterior door that is not a component of the required means of egress; the door, other than an exterior storm or screen door, does not swing over the landing or step; and the doorway is not on an accessible route as required by Chapter 11 and is not part of an Accessible unit, Type A unit or Type B unit.


1008.1.7 Thresholds


1008.1.8 Door arrangement

Space between two doors in a series shall be 48 inches minimum plus the width of a door swinging into the space. Doors in a series shall swing either in the same direction or away from the space between the doors.

Exceptions:

1. The minimum distance between horizontal sliding power-operated doors in a series shall be 48 inches.

1008.1.8 Door arrangement

• The 48” clear distance between doors when the first door is open allows an occupant, including a person using a wheelchair, to move past one door and its swing before beginning the operation of the next door

• Where doors in a series are not arranged in a straight line, the intent of the code is to provide sufficient space to enable occupants to negotiate the second door without being encumbered by the first door's swing arc.
