Housing societies commonly use one of three methods. They may charge a rate per square foot, split the cost equally among flats, or use a combination: shared costs such as security are divided equally, while other costs are based on flat size. For example, at ₹2.50 per sq ft, a 1,200 sq ft flat would have a basic monthly charge of ₹3,000. A separate sinking fund may be collected for major future repairs. To compare apartment maintenance charges in Ahmedabad, look beyond the rate. Ask which flat area is used and whether the estimate covers lifts, security, water systems, common-area electricity and any recreational facilities. Add the full monthly estimate to your flat buying checklist in Ahmedabad. This helps you judge whether the essential amenities in a flat in Ahmedabad are worth their ongoing cost. Laxmi Group’s amenities guide explains these costs with examples that buyers can use when comparing projects. Conclusion: The calculation method varies by society. Ask for the method, included services and any separate charges in writing before booking, so the monthly cost does not come as a surprise.
