Does The Amount Of Leasable Square Feet Include External Walls?

Usable Square Footage (USF) is the total usable floor area of a space or building, measured from the outside or outer surface of any exterior walls and windows. It includes the middle of any interior walls adjacent to other spaces, hallways, or common areas. In architecture, construction, and real estate, floor area is the area taken up by a building or part of it, measured in square feet or square meters.

The difference between usable, rentable, and gross square feet is subtle but extremely important. Usable square footage represents the space the tenant will actually occupy, as it encompasses measurements taken from the outside of exterior walls. Rentable square footage combines the useable square footage with a percentage of the common areas’ square footage, while gross square footage covers the entire square footage of the building.

There are three major metrics for defining “floor area”: Gross Area Footage (GAF), Usable Square Footage (USF), and Rentable Area Footage (RAF). Their differences can dictate lease agreements, property valuations, and space planning.

To get the gross leasable area for one tenant, measure from the center of the common wall (shared with another tenant) to the outside face of the external wall. The external wall can be a shopfront, a window display, or just a flat wall. Regardless, it is included in the gross leasable area.

Leasable square footage means the amount of space in the premises as measured from the middle of common walls and the exterior of outside walls. It encompasses measurements taken from the outer surface of exterior walls and windows, including the midpoints of interior walls adjoining them.

In summary, usable square feet (USF) is the total usable floor area of a space or building, measured from the outside of exterior walls and windows. Gross square footage (GFA) is the total property square footage, including all floor space within the walls of the area being leased.

Does GFA include external walls?

Gross floor area (GFA) in real estate refers to the total floor area inside a building, including external walls and roof. Definitions of GFA vary globally, and some developers use GLA and GFA interchangeably, excluding public areas like corridors. Hong Kong law Chapter 123F, Building (Planning) Regulations, Regulation 23 sect 3 sub-paragraph (a) defines GFA as the area within the external walls of a building measured at each floor level, including any floor below ground level. The area of each balcony in the building is calculated from the overall dimensions of the balcony and the thickness of the external walls of the building.

Do walls take away square footage?

Removing a wall can create a more spacious living space within a home, but it doesn’t increase the property’s total square footage. Square footage is calculated based on the building’s dimensions, including exterior walls. Interior wall removal redistributes existing square footage, creating a more open and connected living space. Benefits include improved flow, better natural light distribution, and aesthetic enhancement.

Open floor plans are desirable in modern home design, fostering a cohesive living environment. However, consulting a professional is crucial as some walls are load-bearing and can cause serious structural issues and compromise home safety.

How to calculate leasable area?

Gross leasable area (GLA) is a measure of the area between a wall and the lease line in common areas, including unshared walls.

How do you calculate external wall area?

To calculate the ground floor area of a house, measure the length and width of the house and multiply them together. If outside measurements are unavailable, measure inside and add the wall thickness. Include an integral garage in the calculation. For upstairs, double the ground floor area or treble it if the other floor area is different. Other factors to consider include perimeter wall thickness, internal walls, partitions, columns, piers, chimney breasts, stairwells, roofs, lift-wells, integral garages, conservatories, attached garages, canopies, open vehicle parking areas, terraces, greenhouses, garden stores, and external fuel stores.

How do I figure out the square footage of the outside of my house?

To measure square footage of a property, draw a rough sketch of the entire space, labeling all rooms, including hallways and vestibules. Measure the length and width of each room, multiplying them by the length and width to calculate the square footage. For example, a bedroom measuring 12 feet by 20 feet would be 240 square feet. For each room, write the total square footage in the corresponding space on the sketch. Add up all measurements to determine the total square footage of the property. This method is useful for properties with complex floor plans.

How do you calculate square footage of exterior walls?

In order to calculate the square footage of a room, it is necessary to measure the height and width of each side and then multiply these measurements together in order to obtain the total square footage. In addition to the aforementioned measurements, it is necessary to take into account any other areas that are not included in the sides, such as gables and dormers. In the case of triangular areas, the measurement should be taken from the base to the apex and then multiplied by half the length of the base.

Does gross square footage include exterior walls?

The term “building floor area” is defined as all areas on all floors, including vertical penetration areas for circulation and shaft areas connecting floors, within the exterior faces of the walls.

How to calculate cleanable square footage?

To calculate the cleanable square footage of a space, subtract non-cleaning areas from the total building square footage and use this to calculate a custodial price per square foot. Commercial cleaning services can range from $. 05 to $. 25 per square foot, depending on the facility type and size. An example is 7, 000 cleanable sq. ft. X $. 20/sq. ft. = $1, 400 estimate.

Additionally, calculate the employee wage by determining the time it will take to complete the job and the number of employees needed. Multiply the number of employees and their hourly rate by the hours it will take to clean the facility. For example, if a job requires three employees at $10 an hour and six hours, the cost to staff the job would be $180.

What is not included in GFA?

Gross Floor Area (GFA) is the total area within a building’s external walls, including all floors. It is crucial for understanding the available space, including areas like offices, retail spaces, residential apartments, and accessible areas. GFA is calculated by summing up all covered and enclosed spaces within a building, starting with the external surface area of each floor. It excludes areas not covered by the roof, open terraces, or spaces used exclusively for mechanical services.

What is an example of a leasable area?

The term “leased area” is used to describe the portion of a building that is accessible to tenants, inclusive of common areas, elevators, bathrooms, and stairwells. The measurement is typically taken from the center of the partition walls to the exterior wall surfaces, and it encompasses areas that are not occupied by tenants.

When calculating square footage do you include walls?

Square footage of a home is calculated from the outside dimensions of the structure, including exterior and interior wall thickness. To calculate, use a 100-foot tape measure and walk around the exterior, measuring each segment and drawing the shape. If the exterior has square corners, take measurements at the foundation and round to the nearest half foot. If overhangs or slopes make exterior measurements difficult, measure from the inside and add the width of each exterior wall. Break the shape into a series of rectangles and use simple math to calculate the square footage.
