48
occupancy load table
IBC 2004.1.2
49
which two requirements must you meet for egress stair width?
Min width requirements (IBC 1011.2) and width bases on occupancy loads (IBC 1005.3.1)
50
which two requirements must you meet for egress door width?
min width req (1010.11) and width based on occ load (1005.3.2)
51
which two requirements must you meet for egress corridor width?
min width req (1020.1.2) and width based on occ load (1005.3.2)
52
at what heights (max and min) must accessible signage be installed?

53
what floor clearance do you need in front of accessible signage?
18" x 18"
54
what does the centerline of ADA signage need to be from a door at minimum?
9" min
55
What is the maximum slope before accessible ramps are required?
5%
56
When does a project trigger an ADA compliance requirement?
New buildings require accessibility if: they are (1) places of public accommodation (businesses with a public-facing entrance like banks, hotels, restaurants, doctor’s offices, etc.) or (2) commercial spaces that need to be accessed by people with disabilities. Renovated existing non-compliant buildings require accessibility if: (1) a primary function area is part of the alteration (the teller station of a bank, the lobby of a hotel, the dining room of a restaurant, or the waiting room of a doctor’s office). . . if making the room accessible will exceed 20% of the total cost of the building alteration, then the ADA requirement is considered “disproportionate” and you can cap your accessibility-related spending at 20%, provided you make ADA alterations in this reasonable order of priority until you hit 20% of your budget: entrance; route to the primary function area; at least one unisex restroom or one restroom for each sex serving the area; public telephones serving the area; drinking fountains serving the area; other elements.

max 1⁄2” height with beveled edge 1⁄4” max height transition
85
How far do smoke baffles extend down?
24"
86
What is the rule with fire separation distance from neighboring buildings?
If your exterior wall has a fire separation distance from the neighboring building greater than 5’, your fire rating only needs to account for interior fire exposure. If your exterior wall has a fire separation distance from the neighboring building less than 5’, your fire rating must account for both interior and exterior fire exposure.
87
What is a planned use development?
developments are agreements made typically between a city/town council and a developer in which the council agrees to change their zoning rules for the developer if the developer does something that the council wants. Similar to overlay districts but here the ask is of the governing body from the developer for an exception for a specific (large) site, instead of from the city to all developers for a predetermined zone.
