Reduce Construction Cost for Fast Casual and Take Out Restaurants

When building a restaurant for fast casual dining or take out, design for the best building type to save on construction cost.

Assembly Group A-2 Classification is the Use/Occupancy Type for Restaurant Design and Construction

When planning a restaurant renovation or a new restaurant building, there are construction requirements you should keep in mind.

First, the restaurant building is an Assembly Occupancy Classification. To receive a Use and Occupancy Permit for a restaurant, you must meet International Building Codes requirements for Assembly Group A-2. This assembly classification that is typical for many architects and contractors, so restaurant owners can easily find experienced professionals in most cities.

Second, you need the occupant load. The use of areas within the buildings determine the occupant load. For A-2, the typical use areas would include:

Assembly with fixed seats: 1 person per seat

Assembly without fixed seats:

  • Standing Space 5 net sf per person
  • Chairs only 7 net sf per person
  • Tables and chairs 15 net sf per person

Kitchen, commercial: 200 gross sf per person

Accessory storage areas: 300 gross sf per person

The best building type for fast casual and take out restaurant in terms of COST FOR CONSTRUCTION is:

– Construction Type V-B building

– No fire sprinkler system

– Single story

– Less than 6,000 square feet.

This Construction Type includes no cost for plumbing upgrades for a costly sprinkler system, no cost for fire resistant construction at walls and roofs, and no fire separation within the restaurant (i.e. the dining and kitchen do not need a separation wall).

Planning for Occupant Load

Occupant Load is determined by the use of areas in the building. For Group A-2, the typical use areas would include:

Assembly with fixed seats:   1 person per seat

Assembly without fixed seats:

  • Standing Space        5 net sf per person
  • Chairs only                 7 net sf per person
  • Tables and chairs    15 net sf per person

Kitchen, commercial:       200 gross sf per person

Accessory storage areas:  300 gross sf per person

 

For Group A-2 Occupancy with fixed seating, the seats are counted to determine the occupant load.  Seating for multiple people without dividing arms (like benches) are calculated at 18 linear inches of seating length per person.

Additional occupied space (like a waiting area) is calculated using the occupant load factor for that space, which is then added to the number of fixed seats.

Designing within Net and Gross Floor Area

Gross floor area is measured within the inside surface of the walls, and includes all occupiable and non occupiable spaces. Bathrooms, closets, electrical/mechanical rooms, and other non occupiable spaces are never subtracted from the gross floor area.

Net floor area is calculated for occupied areas only. Non occupied spaces like corridors, stairs, bathrooms, electrical/mechanical rooms, closets, and fixed equipment are subtracted from the gross floor area to determine the net floor area.
