Apartment Maintenance Charges in Bangalore: Corpus, GST and Red Flags

The EMI is not the only monthly cost of owning a flat. Every gated community also bills its owners for security, lifts, power backup, gardening and cleaning, and in a large project with a clubhouse that bill can be significant. This guide explains how apartment maintenance charges in Bangalore are set, what you pay at handover, when GST applies, and the warning signs to look for before you buy.

How apartment maintenance charges in Bangalore are calculated

Most Bangalore apartments bill maintenance per square foot per month. The rate is applied to either the super built-up area or the carpet area, depending on the project, so a 1,200 sq ft flat pays more than an 800 sq ft flat in the same building. Some smaller buildings split costs equally per flat instead, and a few use a mix of a fixed charge plus a per-sq-ft component.

The rate itself comes from the annual budget. The builder (in the early years) or the owners' association adds up the expected yearly cost and divides it by the total billable area. The main items are usually:

• Security guards and housekeeping staff
• Lift, generator, STP, water treatment and pump maintenance
• Electricity for common areas, including lifts and street lights
• Water tanker costs, which can be a large line item in areas with poor Cauvery supply
• Clubhouse, pool and gym running costs
• Facility management company fees and admin
• Insurance for the building and common areas

Typical ranges as of 2026

As a rough guide, many Bangalore apartments charge somewhere between ₹2 and ₹7 per sq ft per month. Older or smaller buildings with few amenities sit at the lower end. Large gated communities in places like Whitefield, Sarjapur Road, Hebbal or Kanakapura Road, with clubhouses, pools and several lifts per tower, are often at the higher end.

For a 1,200 sq ft flat, that works out to roughly ₹2,400 to ₹8,400 a month before GST. Many associations also collect a separate sinking fund contribution, which some recent guides put at roughly ₹0.5 to ₹1.5 per sq ft per month.

Be careful with a quoted rate that looks very low for the amenities on offer. It often means the reserve is thin and owners will face a special levy later, for example when lifts or generators need replacing.

What you pay at handover: advance maintenance and corpus fund

When you take possession of a new flat, the builder's demand letter usually includes two maintenance-related items. Both are worth reading carefully in the agreement for sale before you book.

Advance maintenance

Builders commonly collect maintenance in advance for the first year, and sometimes two years, at handover. This pays for running the project while it fills up and before the association takes over. Ask what rate it is based on, whether GST is added, and what happens to any unused balance when the association takes charge.

Corpus fund

The corpus fund is a one-time deposit, usually charged per square foot, that is meant to be handed over to the owners' association. It is a reserve for large future expenses such as repainting the building, replacing lifts or major repairs. In bigger projects the corpus for one flat can run into a lakh or more.

The key point is that the corpus belongs to the owners. Your sale agreement should say clearly that the builder will transfer the full corpus, with any interest earned, to the association once it is formed.

Sinking fund versus corpus

People often use these terms interchangeably. Generally, the corpus is the one-time lump sum collected at handover, while a sinking fund is built up through regular monthly or yearly contributions. Both are meant for large repairs, not day-to-day running costs.

When GST applies to maintenance charges

GST on apartment maintenance trips up a lot of owners. Under the rules clarified by the Finance Ministry, an owners' association has to charge 18% GST on maintenance only when both of these are true:

• The maintenance charge is more than ₹7,500 per month per flat, and
• The association's annual turnover is more than ₹20 lakh.

If the monthly charge crosses ₹7,500, GST applies to the whole amount, not just the part above ₹7,500. A ₹9,000 monthly bill, for example, attracts GST on the full ₹9,000, which is ₹1,620. If you own two flats in the same complex, the ₹7,500 limit is applied separately to each flat.

Things are different before the association takes over. When the builder or its facility management company collects maintenance as a business, GST is often charged regardless of these limits. Water and electricity charges collected as pass-through amounts may also be treated differently. Tax rules change, so check the latest before you buy and ask for a clear breakup.

Handover from builder to owners' association

In the early years, the builder runs the property, usually through a facility management company. Over time, control should pass to the owners. Two sets of rules matter in Bangalore.

What RERA requires

Under the Real Estate (Regulation and Development) Act, 2016, the builder must help the buyers form an association, and is responsible for essential services until the association takes over. RERA also requires common areas to be handed over to the association, generally within a set period after the occupancy certificate. You can raise a complaint with RERA Karnataka if a builder keeps delaying this.

The Karnataka Apartment Ownership Act, 1972

Many Bangalore projects form their association under the Karnataka Apartment Ownership Act, 1972 (KAOA). Under this route, the builder executes a Deed of Declaration and registers it at the sub-registrar's office, and the association runs under its bye-laws. Other projects register the association as a society under the Karnataka Societies Registration Act, 1960, which is simpler to set up. The KAOA route is often recommended because the registered Deed of Declaration records each owner's share in the common areas, but either way, ask which route your project is using.

The state has also published a draft Karnataka Apartment (Ownership and Management) Bill, 2025, which proposes replacing the 1972 law with a single framework for apartment associations. As of this writing it is still at the proposal stage, so check its current status before relying on it.

Once the association takes over, it sets the budget, appoints vendors, and can revise maintenance at the annual general meeting. That is often when rates change, up or down, as owners see the real costs.

Red flags to check before you buy

1. No written maintenance terms. The rate, the basis (carpet or super built-up area) and the advance period should be in the agreement for sale.

2. Corpus not tied to the association. If the agreement does not say the corpus will be transferred to the owners, ask why.

3. Long builder control. A builder or its own facility company running the project for years after most flats are occupied can lead to high charges and little transparency.

4. No audited accounts. In a resale or ready project, ask the association for the last year's accounts and budget.

5. Heavy tanker dependence. Check whether the project has a Cauvery connection or depends on borewells and tankers, since water can be the biggest variable cost.

6. Pending dues. In a resale purchase, get a no-dues letter from the association so you do not inherit the seller's arrears.
