Renovating a Society Flat: NOCs, Rules and Balcony Changes

Renovating a flat in a housing society is not like renovating an independent house. Your walls, slab and balcony are part of a shared building, and the law gives your neighbours and the apartment owners’ association (AOA) a say in what you can change. Get this wrong and you may face a stop-work notice, a dispute with the flat below, or an order to undo the work at your own cost.

This guide explains what needs permission in Noida, Greater Noida, Ghaziabad and Gurugram societies, the structural limits, the practical rules most societies apply, and what the law says about balcony enclosures.

The legal framework in brief

Uttar Pradesh: the UP Apartment Act, 2010

Societies in Noida, Greater Noida, Greater Noida West and Ghaziabad fall under the Uttar Pradesh Apartment (Promotion of Construction, Ownership and Maintenance) Act, 2010. Three provisions matter most for renovation:

• Section 6(1): every owner must comply with the bye-laws and the covenants in the deed of apartment. If they do not, the AOA’s board or an affected owner can seek damages, an injunction, or both.
• Section 6(2): no owner may do work that harms the soundness or safety of the building, reduces its value, adds a material structure or alters the external facade without first obtaining the consent of all the apartment owners in that building.
• Section 5(6) and 5(7): work on common areas must follow the Act and bye-laws, and the AOA has a right of access to flats at reasonable hours for maintenance and emergency repairs.

AOAs must adopt the state’s model bye-laws, notified in November 2011. According to a legal explainer on balcony changes, the model bye-laws require an owner to notify the AOA board before starting work, and the board must respond within 30 days, failing which the work is treated as not objected to. Where an owner makes unapproved changes, the cost of correcting them falls on that owner.

Haryana: the Apartment Ownership Act, 1983

In Gurugram and Faridabad societies, the Haryana Apartment Ownership Act, 1983 applies. Section 8 bars an owner from work that would jeopardise the building’s soundness or safety, reduce its value or impair an easement, and from adding any material structure or excavating a basement, without the consent of the other apartment owners. There is no single public rulebook for flat interiors in Gurugram, so the society’s declaration, bye-laws and the sanctioned building plan decide most questions in practice.

What usually needs permission, and what does not

Structural limits: what you must not touch

Many NCR high-rises are built with reinforced concrete shear walls, where a large share of the walls inside a flat carry load. A wall that looks like an ordinary partition may be part of the structure. Before removing or cutting any wall, ask the society for the structural drawings and have a structural engineer confirm in writing that the wall is non-load-bearing.

Never cut, chase deeply into, or core through columns, beams, shear walls or slabs. Avoid heavy demolition hammers for tile removal, because vibration can damage the structure and neighbouring flats. Do not increase load significantly, for example with heavy stone flooring on a balcony or a large aquarium, without an engineer’s advice.

A practical point for new flats: under RERA, a builder must fix structural defects and workmanship problems reported within five years of possession, free of charge within 30 days. If you alter the area concerned, the builder may dispute responsibility. Report any defects and get them fixed before you renovate.

Bathrooms and kitchens: protecting the flat below

Wet-area work causes the most neighbour disputes after balconies, because a mistake shows up as seepage in someone else’s ceiling. When you replace bathroom tiles, the old waterproofing layer is usually broken, so it must be redone across the whole floor and up the walls, not just patched. Ask your contractor to leave the new waterproofing layer flooded with water for a day or two before tiling, and invite the owner below to check their ceiling.

Do not shift toilets, floor traps or kitchen sinks far from the original drain points. Drains in a high-rise run through shared shafts, and new pipe routes through the slab can leak into the flat below or weaken it. If a change is unavoidable, get the plumber’s layout approved by the society and keep it on record.

Balcony changes: the most disputed area

Balcony enclosures cause more disputes than any other renovation. The reasons are partly legal and partly practical.

• Facade: covering a balcony changes the building’s external appearance, which under the UP Act needs consent from all the owners in the building. A legal explainer on Noida notes that permanent enclosure, such as with brick, is not allowed.
• Floor area: an enclosed balcony can be treated as additional covered area, which may breach the sanctioned plan and building rules.
• Fire safety: balconies can be part of the escape and ventilation design, and enclosures can block access in an emergency.

In Delhi’s DDA flats, lawyers note that some balcony and terrace covering is allowed under DDA’s own rules, with certified drawings and additional fees. That is a DDA-specific system and does not carry over to private societies in Noida or Gurugram.

What is generally acceptable: replacing balcony floor tiles, tiling walls and small planters, provided waterproofing is done properly. Keep pots and heavy items off the parapet. After a child in Pune was killed by a falling flowerpot in April 2025, the Noida Authority issued an advisory against items on balcony parapets, and RWAs in Noida, Gurugram and Ghaziabad followed with their own notices.

If you want an enclosure for dust or safety, ask the AOA whether it has approved a uniform design, such as a standard invisible grill or a removable sliding system. A uniform approved design is far more likely to be accepted than a one-off structure.

Practical rules most societies apply

The details differ, but most NCR societies set rules on:

• Prior application: a written request with the scope of work, contractor details and expected duration.
• Refundable deposit: held against damage to lifts, common corridors or other flats, returned after inspection.
• Work hours: noisy work usually allowed only during weekday daytime hours, with no work on Sundays or holidays in many societies.
• Debris: removal in bags, by service lift only, within a set time, to a designated point.
• Labour entry: worker ID lists and entry passes.
• Lift protection: covering the service lift interior while materials are moved.

Separately, national noise rules prohibit loudspeakers and public address systems between 10 pm and 6 am except in closed premises, and societies often apply similar quiet hours to building work.

A worked example: if your society asks for a refundable deposit of ₹25,000 and your contractor scratches the lift panels, the repair cost is deducted before the balance is returned. Ask for the deposit terms in writing and photograph common areas, including the lift, before work starts.

Air-quality restrictions in NCR

Renovation in NCR also has to fit around the Graded Response Action Plan (GRAP), which the Commission for Air Quality Management revised in September 2026. At Stage III, triggered when Delhi’s AQI enters the ‘severe’ range, restrictions apply across NCR to dust-heavy work. These include all demolition, brick and masonry work, cutting and grinding of tiles and stone, cement and plaster work, and painting, polishing and varnishing. Minor indoor repairs and maintenance are exempted from the tile and plaster restrictions, and minor welding for mechanical, electrical and plumbing work is permitted. Plan major work outside the October to January pollution season, or be ready for pauses.

Step-by-step: getting a renovation approved

1. Read your society’s bye-laws and renovation rules, and your deed of apartment.
2. Get the structural drawings for your flat from the AOA or builder.
3. Prepare a written scope of work, with drawings for any wall or plumbing change.
4. Get a structural engineer’s letter for any wall removal.
5. Submit the application and deposit to the AOA, and keep the acknowledgement.
6. Inform the neighbours on either side and the flat below, especially for bathroom work.
7. Photograph common areas before work starts and after it ends.
8. Get the deposit back after a joint inspection.

If the AOA refuses

Ask for the refusal and its reasons in writing. Check them against the bye-laws: an AOA cannot invent rules that conflict with the Act or the model bye-laws, but it can refuse facade and structural changes that need wider consent. If you believe a refusal is arbitrary, raise it at the general body meeting, or approach the Deputy Registrar of societies. Legal advice is worthwhile before starting any disputed work, because the AOA can seek an injunction and recovery of correction costs.
