Water Leakage From the Flat Above: Who Pays and How to Fix It

Water leakage from an upper floor flat is one of the most common disputes in Delhi NCR apartments and builder floors. Most cases settle once three questions are answered with evidence: where is the water coming from, who owns that part of the building, and is the builder still liable?

This guide covers liability between neighbours, the Association of Apartment Owners (AOA) and the builder, diagnosis, repairs and legal routes. It is general information, not legal advice.

First, find out what kind of space is leaking

Liability almost always follows ownership. Apartment laws in the NCR states split a building into two parts: the individual apartment, which the owner controls and maintains, and the common areas and facilities, which belong to all owners together and are looked after by the association.

The UP Apartment (Promotion of Construction, Ownership and Maintenance) Act, 2010, which covers Noida, Greater Noida and Ghaziabad, lists common areas to include the foundations, columns, beams, main walls, roofs and terraces, corridors, lobbies and stairs, along with installations of central services such as water and sanitation. The Real Estate (Regulation and Development) Act, 2016 (RERA) uses a similar definition that names central water and sanitation installations, water tanks, sumps and motors. Gurugram and Faridabad fall under the Haryana Apartment Ownership Act, 1983, and Delhi has the Delhi Apartment Ownership Act, 1986, both built on the same idea. In Delhi cooperative group housing societies, the society’s bye-laws also matter.

In plain terms:

• Inside the flat above: the bathroom floor waterproofing, the floor trap, the branch pipe running from the WC or wash basin to the main stack, a kitchen sink outlet, a balcony drain inside that flat. These are usually the upstairs owner’s responsibility.
• Shared services: the vertical soil or rainwater stack serving several floors, the overhead tank, the main supply riser, the terrace and its waterproofing, and external walls. These are usually the AOA’s (or the builder’s, before handover) responsibility.
• Your own flat: condensation, a leaking concealed pipe in your own wall, or a failed joint in your own bathroom can look like seepage from above. Rule these out first.

Your sale deed, deed of apartment (deed of declaration in UP) and the society bye-laws may draw the line differently in specific cases, so read them before assigning blame.

Who pays: a quick liability table

What the apartment laws say about access and damage

The association’s right of entry. Section 5 of the UP Act gives the AOA an irrevocable right, exercised through its board or manager, to access any apartment during reasonable hours to maintain, repair or replace common areas, and to carry out emergency repairs needed to prevent damage to common areas or to other apartments. The Haryana and Delhi Acts carry an almost identical clause. So if the upstairs owner refuses entry while a common stack is leaking into your flat, the association has a legal basis to insist.

The owner’s duty to follow the rules. Section 6 of the UP Act requires every owner to comply with the bye-laws and the deed of apartment, and says a failure to comply can lead to an action for damages, an injunction, or both, brought by the association or, in a proper case, by an aggrieved owner. It also bars work that harms the soundness or safety of the property, which covers a renovation that leaves the waterproofing damaged. The Delhi Act has an equivalent clause.

When the builder pays: RERA Section 14(3)

If your building is fairly new, check the possession date before spending your own money. Under Section 14(3) of RERA, if a structural defect or any other defect in workmanship, quality or provision of services is brought to the builder’s notice by the allottee within five years from the date of handing over possession, the builder must fix it free of charge within 30 days. If the builder fails, the allottee can claim compensation under the Act.

Seepage caused by poor bathroom waterproofing, badly jointed concealed pipes or a defective terrace treatment often fits this description. Practical points:

• The notice should go in writing (email plus a letter you can prove was delivered) with photos, dates and a description of the defect.
• If the source is in the flat above, the upstairs owner, as the allottee of that unit, may need to raise it too, or you may file jointly. Where the defect is in a common area, the AOA can take it up for all owners.
• Complaints go to the state RERA authority under Section 31 (UP RERA for Noida, Greater Noida and Ghaziabad; Haryana RERA Gurugram for Gurugram). Compensation claims are decided by the adjudicating officer under Section 71.
• Owners who bought on resale should check with a lawyer how their sale documents treat the original allottee’s rights.

Diagnose before you argue

A Delhi civil court case shows why proof matters. In Jhumur Chatterjee vs Hemant Gupta (South East District, Saket, 16 October 2024), a ground-floor owner sued the upstairs neighbour for ₹11.75 lakh in damages over seepage. The suit was dismissed, with the court noting that the plaintiff had not been able to prove the source of the seepage. Whatever your route, a clear diagnosis is the foundation.

Step 1: Record the damage

Take dated photos every few days. Constant damp suggests a pressurised supply pipe; damp linked to upstairs bath times points to drainage or floor waterproofing; damp only in the monsoon points to the terrace or external walls.

Step 2: Moisture meter mapping

A moisture meter estimates water in plaster or concrete using electrical resistance or dielectric readings. A plumber or waterproofing contractor can map readings across the ceiling and walls. The wettest point is usually near the source, though water can travel along slabs before it shows.

Step 3: Ponding (flood) test

With the upstairs owner’s consent, the floor drain in the suspect bathroom is plugged and the floor is filled with a few centimetres of water, which is left for a day or more. If the patch below grows or the water level drops, the floor waterproofing has failed. Do this test separately for the bathroom, balcony and kitchen so you know which area is at fault.

Step 4: Plumbing pressure test

Supply lines are tested by filling them, shutting the inlet valve and watching a pressure gauge. A falling reading means a leak in that line. Drain pipes are checked by running water through each fixture in turn while someone watches the ceiling below. Dye in the water makes it easier to identify which outlet is leaking.

Step 5: Get it in writing

Ask for a short signed report naming the source, the tests done and the recommended repair, and share it with the upstairs owner and the AOA. This one document often ends the argument.

Repair options and indicative costs

The right fix depends on the source. The figures below are indicative only, based on typical quotes and not from any official rate schedule; actual prices in Noida, Gurugram, Ghaziabad or Delhi vary with materials, access, tile choice and labour rates, so take at least two written quotes.

Two rules save money. First, do not repaint your ceiling until the source is fixed and the slab has dried; otherwise you will repaint twice. Second, insist on a ponding test after any new waterproofing, before tiles are laid.

Worked example: splitting the bill

Suppose you live on the fourth floor of a Noida society. Your bathroom ceiling has been damp for three months. A moisture meter and ponding test show two sources: failed waterproofing in the fifth-floor bathroom, and a cracked joint on the common soil stack in the shaft.

• Waterproofing redo upstairs: ₹75,000, payable by the fifth-floor owner.
• Stack joint repair: ₹12,000, payable by the AOA from common maintenance funds.
• Ceiling restoration in your flat: ₹14,000. A fair settlement apportions this by cause; if the report attributes most of the damp to the upstairs bathroom, the owner might bear, say, ₹10,000 and the AOA ₹4,000.

Now suppose the society got possession in 2023. Both defects were raised in October 2026, within five years of handover, so all three items could instead be claimed from the builder under Section 14(3). The upstairs owner and the AOA should serve notice on the builder before paying out of pocket, while keeping a record of any emergency spending to claim later.

If talks fail: your options

1. AOA intervention

File a written complaint with the AOA, ask for an inspection and get its decision in writing.

2. Mediation

The Mediation Act, 2023 provides for community mediation of disputes affecting harmony among residents of an area, with both parties’ consent, through a panel set up by the local legal services authority or the district magistrate. Ask your District Legal Services Authority whether this is available in your district, as roll-out can vary. A settlement signed by both parties and authenticated by the mediator is binding under the Act.

3. Civil suit for injunction and damages

Persistent seepage can be treated as a nuisance. A civil court can order the neighbour to carry out repairs (a mandatory injunction) and pay damages. In Deepak Gahlot vs Seema Maheshwari (South West District, Dwarka, 14 January 2026), a Delhi court awarded the lower-floor owner ₹50,000 in damages with 6% annual interest and directed the first-floor occupants to repair the plumbing, toilet, kitchen and balcony areas within 60 days. It also allowed the plaintiff to seek a local commissioner to get the work done at the defendants’ cost if they did not comply. The evidence included dated photos, an inspection report and earlier written complaints. Both rulings are district-level and fact-specific, not binding precedents.

4. RERA or consumer commission against the builder

For defects within the RERA five-year window, the state RERA authority is the natural forum. Allottees can also approach a consumer commission for deficiency in service. Under the 2021 jurisdiction rules, the District Commission hears complaints where the consideration paid is up to ₹50 lakh, the State Commission above ₹50 lakh and up to ₹2 crore, and the National Commission above ₹2 crore. A complaint should normally be filed within two years of the cause of action under Section 69 of the Consumer Protection Act, 2019. RERA Section 79 bars civil courts from matters the RERA authority can decide, so take advice on which forum fits your claim.

Example: an owner who paid ₹85 lakh for a flat in Greater Noida West would file a consumer complaint against the builder before the UP State Commission, not the District Commission, because the consideration exceeds ₹50 lakh.

A practical checklist

1. Photograph and date the damage; note when it gets worse.
2. Rule out sources inside your own flat.
3. Speak to the upstairs owner calmly, then follow up in writing.
4. Get a moisture meter survey, ponding test and pressure test, with a signed report.
5. Decide who is responsible using the report, your deed and the bye-laws.
6. Check the possession date for a RERA Section 14(3) claim.
7. Escalate to the AOA, then mediation, then RERA, consumer commission or civil court.
