In the case of Raj Kumar Gambir (supra), it was held that if a small portion of the building is used for residential purposes, the dominant purpose being business or trade, the building will continue to be “nonresidential building”.

In that case, the landlord was residing on the first floor and a room on the right side on the ground floor was let out for a small shop.
