How society maintenance charges are calculated
Per square foot or equal per flat? The answer is not a matter of committee preference — the model bye-laws prescribe a basis for each head. This is what your bill is actually made of.
Society maintenance is not one charge but several heads, each with its own apportionment basis. Under the widely used model bye-laws, service charges are divided equally per flat, while sinking fund, repair fund and property-tax-linked heads are apportioned by area. Most societies therefore run a hybrid, not a single per-square-foot rate.
What maintenance charges actually cover
Maintenance is the recovery of what it costs to run the property, and it is worth seeing the composition before arguing about the rate. In a typical Indian residential society the largest components are security — usually the single biggest line — housekeeping, common area electricity including lifts and pumps, lift maintenance contracts, water, and the wages of directly employed staff.
Sitting alongside those operating costs are the funds: the sinking fund for eventual major structural work, and the repair and maintenance fund for planned repairs. These are not expenses in the year they are collected; they are accumulations against future liabilities, and a society that treats them as spending money will discover the shortfall a decade later when the building needs it.
Then there are pass-through and property-specific items: property tax where the society collects it, non-occupancy charges on tenanted flats, parking charges, insurance, and the society’s own administrative costs including audit and professional fees. A member who understands that the bill is a set of distinct heads with distinct bases is a member far less likely to treat the total as arbitrary.
- Security is usually the largest single head. Often a third or more of the operating cost in a guarded property.
- Funds are not expenses. Sinking and repair fund collections accumulate against future liabilities.
- Some heads are pass-through. Property tax and water may simply be collected and remitted.
Methods of calculation
Three approaches are in use, and the choice between them is less free than most committees assume.
Per square foot
The head is divided across the total area of all flats and charged at a rate per square foot of each flat’s area. A 1,200 sq ft flat pays twice what a 600 sq ft flat pays. Whether the area used is carpet, built-up or super built-up should be stated explicitly and applied consistently — the difference between these is substantial, and societies that have never written down which they use invariably find inconsistencies.
This basis suits heads where the cost genuinely scales with area or with the value of the unit: sinking fund, repair fund, insurance, and property-tax-linked charges. It is intuitively fair to owners of small flats and is often resisted by owners of large ones.
Equal per flat
The head is divided equally across all flats regardless of size. Every unit pays the same. This suits heads where consumption does not scale with area: the lift serves a studio and a penthouse equally, as do the security guards, the housekeeping of common areas, and the society’s administrative costs.
The widely used model bye-laws in fact prescribe equal division for service charges, which is the head containing most of the day-to-day operating cost. Societies that charge everything per square foot are frequently at odds with their own bye-laws on this point without realising it.
Hybrid methods
In practice, and under the model bye-laws, a society applies different bases to different heads: service charges equally per flat, sinking and repair funds by area, water by consumption where metered or by taps or occupancy where not, parking per allotted slot, and non-occupancy as a percentage of service charges on tenanted flats.
This is the correct answer for most societies and also the one that generates the fewest disputes, because each head can be explained on its own logic. It requires billing software that can hold several bases at once, which is precisely why single-rate spreadsheets tend to collapse into unfairness.
Charge heads on your bill, explained
Nine or ten heads appear on a typical society bill. These are the groups they fall into.
Service and common charges
Service charges cover the running of the property: security, housekeeping, common area electricity and water, lift operation, garden maintenance, pest control, staff salaries, and the society’s office and administrative expenses including audit fees and professional charges.
Under the model bye-laws this head is divided equally among all flats. It is usually the largest head on the bill, which is why the basis on which it is divided is the single most consequential billing decision a society makes.
Sinking and repair funds
The sinking fund accumulates for eventual major structural work — reconstruction, major structural repair, replacement of major equipment at the end of its life. The repair and maintenance fund covers planned recurring repair: painting, waterproofing, plumbing renewal, road resurfacing.
Both are typically apportioned by area, and both are collected at rates the general body resolves within the minimums the bye-laws prescribe. A society collecting the bare minimum for a decade will generally find it insufficient when the work becomes necessary, which is an argument to have early rather than at the point of need.
Utility and other charges
Water is charged by consumption where sub-meters exist, and otherwise by a proxy the bye-laws permit — commonly the number of water inlets in the flat, or equal division. Electricity for individual flats is usually billed directly by the utility and does not appear on the society bill at all; only common area consumption does.
Other heads include property tax where the society collects and remits it, insurance, parking charges per allotted slot, non-occupancy charges on tenanted flats, and lease rent where the land is leasehold. Each should be a separate line, not blended into a single figure.
Heads and their apportionment basis
The pattern under the widely used model bye-laws is equal division for operating costs and area-based apportionment for funds and value-linked heads.
| Head | Common basis | Notes |
|---|---|---|
| Service charges | Equally per flat | Security, housekeeping, common utilities, staff, administration |
| Sinking fund | By area | Minimum contribution set by the bye-laws; resolved by the general body |
| Repair and maintenance fund | By area | Planned repair; distinct from the sinking fund |
| Water charges | By consumption, taps or equally | By consumption where metered; otherwise as the bye-laws permit |
| Property tax | As levied per flat | Where the society collects and remits it |
| Non-occupancy charges | Percentage of service charges | On tenanted flats only, subject to the applicable cap |
| Parking charges | Per allotted slot | Follows the allotment, not the flat size |
| Insurance | By area | Building insurance apportioned across units |
Rules and caps to know
The rate is fixed by the general body, not by the committee. A committee that raises maintenance by resolution of the committee alone has generally exceeded its powers, and the increase is open to challenge. The budget and the rate go to the general body, usually at the AGM, and take effect from the date the resolution specifies.
Several heads carry limits. Non-occupancy charges are capped in Maharashtra at ten per cent of service charges by a state government circular of August 2001, upheld by the Bombay High Court, and societies there cannot exceed it by resolution — a point covered in detail in the separate guide. Interest on arrears is limited by the bye-laws, commonly to twenty-one per cent per annum simple. Transfer charges are capped in Maharashtra by circular. Each of these is jurisdiction-specific and none should be assumed to apply outside the state that issued it.
A head not provided for in the bye-laws generally cannot be levied at all, however reasonable it seems. If a society wants to introduce a genuinely new charge, the route is a bye-law amendment, not a line item added to the bill. Charges introduced without that basis are the ones that get struck out when a member finally contests them.
- The general body fixes the rate. A committee-only increase is open to challenge.
- Several heads are capped. And the caps are usually state circulars, not national law.
- No bye-law, no head. A new charge needs an amendment, not a new line on the bill.
- Apply uniformly. Selective application is what makes a charge unenforceable in practice.
A worked example for a typical society
A 100-flat society with a monthly service cost of ₹2.4 lakh. Flat A is 600 sq ft, owner-occupied, one parking slot. Flat B is 1,200 sq ft, tenanted, two slots.
| Head | Basis | Rate | Flat A (600 sq ft) | Flat B (1,200 sq ft) |
|---|---|---|---|---|
| Service charges | Equal per flat | ₹2,40,000 ÷ 100 flats | ₹2,400 | ₹2,400 |
| Sinking fund | By area | ₹1.00 per sq ft | ₹600 | ₹1,200 |
| Repair fund | By area | ₹0.75 per sq ft | ₹450 | ₹900 |
| Water | Equal per flat | Unmetered | ₹300 | ₹300 |
| Parking | Per slot | ₹200 per slot | ₹200 | ₹400 |
| Non-occupancy | 10% of service charges | Tenanted only | ₹0 | ₹240 |
| Total per month | — | — | ₹3,950 | ₹5,440 |
