Carpet area vs chargeable area for Mumbai offices: what you pay for

Two offices at the same rate per square foot can cost very different amounts. The area definition is usually why.

Carpet area

Carpet area is the usable floor area inside the premises, the space you can actually lay a carpet on. It excludes common areas such as lobbies, corridors, lifts, stairs and service shafts.

Chargeable or saleable area

Chargeable, saleable or super built-up area adds a share of common areas to the carpet area. Landlords often quote rent on this larger figure.

Loading factor

The loading factor is the percentage by which carpet area is increased to reach chargeable area. A higher loading means you pay for more area than you use. Loadings differ between buildings, so compare them as well as the rate.

How the area changes the cost

Rent, maintenance and sometimes parking charges are charged on area. A lower rate on a more loaded area can cost more than a higher rate on a less loaded one. Compare effective rent per usable square foot, not per chargeable square foot.

What to do before you sign

Take these steps:

  • Ask for both carpet and chargeable areas in writing.
  • Ask how the loading was calculated.
  • Check the area against the drawings, and measure on site if needed.
  • Add a measurement or verification clause to the lease.
  • Confirm which area is used for rent, maintenance and any other charge.
