In a mixed-use building with residential over commercial, what are the exterior wall fire-resistance requirements? Does separation distance affect this?
The fire-resistance rating requirements for exterior walls in a mixed-use building (residential above commercial) depend on the type of construction, occupancy groups, and fire separation distance. Here's a breakdown based on the 2021 International Building Code (IBC):
Fire-Resistance Rating:
The fire-resistance rating is determined by Table 601 and Table 705.5 of the IBC.
For mixed-use buildings, the rating is based on the type of construction (e.g., Type I, II, III, etc.) and the fire separation distance.
Impact of Fire Separation Distance:
Greater than 10 feet:
The exterior wall must be rated for fire exposure from the inside only.10 feet or less:
The exterior wall must be rated for fire exposure from both sides.
For example, in a Type IIIA construction, the exterior wall may require a 2-hour fire-resistance rating if the fire separation distance is less than 10 feet. The exact rating depends on the construction type and occupancy.

Minimum plumbing fixture count for a restaurant in Arizona with a maximum occupancy of 250 people?
The minimum plumbing fixture count for a restaurant in Arizona with a maximum occupancy of 250 people is determined by Table 403.1 of the 2018 International Plumbing Code (IPC).
Divide Occupants by Gender:
Assume a 50/50 split unless statistical data supports otherwise.
Male: [250÷2] = 125 occupants
Female: [250÷2] = 125 occupants
Accessibility Requirements for Drinking Fountains
2018 IPC, Section 410.3 and 2018 IBC, Section 1109.5.1 requires that at least two drinking fountains are required: one for wheelchair users and one for standing persons. Alternatively, a single unit with dual spouts meeting both requirements is acceptable.
For Restaurants, Banquet Halls, and Food Courts (Assembly Use Group A-2):
Calculations for 250 Occupants
Water Closets:
Male: 1 per 75 occupants → ⌈125÷75⌉ → 2 required
Female: 1 per 75 occupants → ⌈125÷75⌉ → 2 required
Lavatories:

What are the regulations for rooftop access for firefighting operations in California?
The regulations for rooftop access for firefighting operations in California are outlined in the 2022 California Fire Code (CFC). Here's a summary:
General Rooftop Access Requirements:
Stairway Access to Roof:
New buildings four or more stories above grade plane must provide a stairway to the roof.
The stairway must comply with CFC Section 1011.12 and be marked with signage indicating roof access at street and floor levels.
Exception: Buildings with a roof slope greater than 4:12 (33.3%) are exempt from this requirement.
Code Reference: CFC 2022, Section 504.3
Roof Hatches or Trap Doors:
In buildings without an occupied roof, access may be provided via a roof hatch or trap door with a minimum area of 16 square feet and a minimum dimension of 2 feet.
Code Reference: CFC 2022, Section 1011.12.2
Obstructions on Roofs:
Wires, cables, antennas, or other obstructions must maintain a minimum clearance of 7 feet above the roof surface to avoid hazards to firefighters.
Code Reference: CFC 2022, Section 316.4
Fire Department Access Walkways:
Approved access walkways must be provided from fire apparatus access roads to exterior openings and rooftop access points.
Code Reference: CFC 2022, Section 504.1
Rooftop Equipment and Pathways:
Pathways must be provided to allow safe access for firefighting operations. These pathways must be clear of obstructions and capable of supporting firefighters.

In a mixed-use building with residential over commercial, what are the exterior wall fire-resistance requirements? Does separation distance affect this?
The fire-resistance rating requirements for exterior walls in a mixed-use building (residential above commercial) depend on the type of construction, occupancy groups, and fire separation distance. Here's a breakdown based on the 2021 International Building Code (IBC):
Fire-Resistance Rating:
The fire-resistance rating is determined by Table 601 and Table 705.5 of the IBC.
For mixed-use buildings, the rating is based on the type of construction (e.g., Type I, II, III, etc.) and the fire separation distance.
Impact of Fire Separation Distance:
Greater than 10 feet:
The exterior wall must be rated for fire exposure from the inside only.10 feet or less:
The exterior wall must be rated for fire exposure from both sides.
For example, in a Type IIIA construction, the exterior wall may require a 2-hour fire-resistance rating if the fire separation distance is less than 10 feet. The exact rating depends on the construction type and occupancy.

Minimum plumbing fixture count for a restaurant in Arizona with a maximum occupancy of 250 people?
The minimum plumbing fixture count for a restaurant in Arizona with a maximum occupancy of 250 people is determined by Table 403.1 of the 2018 International Plumbing Code (IPC).
Divide Occupants by Gender:
Assume a 50/50 split unless statistical data supports otherwise.
Male: [250÷2] = 125 occupants
Female: [250÷2] = 125 occupants
Accessibility Requirements for Drinking Fountains
2018 IPC, Section 410.3 and 2018 IBC, Section 1109.5.1 requires that at least two drinking fountains are required: one for wheelchair users and one for standing persons. Alternatively, a single unit with dual spouts meeting both requirements is acceptable.
For Restaurants, Banquet Halls, and Food Courts (Assembly Use Group A-2):
Calculations for 250 Occupants
Water Closets:
Male: 1 per 75 occupants → ⌈125÷75⌉ → 2 required
Female: 1 per 75 occupants → ⌈125÷75⌉ → 2 required
Lavatories:
Male: 1 per 200 occupants → Male: ⌈125÷200⌉ → 1 required
Female: 1 per 200 occupants → Female: ⌈125÷200⌉ → 1 required
Drinking Fountains:
1 per 500 occupants →⌈250÷500⌉ → 1 → 2 to meet accessibility requirements
Service Sink:
1 required

Obstructions on Roofs:
Wires, cables, antennas, or other obstructions must maintain a minimum clearance of 7 feet above the roof surface to avoid hazards to firefighters.
Code Reference: CFC 2022, Section 316.4
Fire Department Access Walkways:
Approved access walkways must be provided from fire apparatus access roads to exterior openings and rooftop access points.
Code Reference: CFC 2022, Section 504.1
