Is Invisible Grill Allowed in Your Society? Mumbai, Bangalore and Delhi NCR Rules After the 2026 Bombay High Court Directive

"Is invisible grill allowed in my society?" has become a sharper question in 2026. The Bombay High Court has told Maharashtra to write statewide rules on which alterations to a flat are permissible — safety grills, balcony enclosures, coverings — and to build an online portal for permissions. Bangalore and Delhi NCR committees are tightening facade rules on new towers. This guide explains what the law and the bye-laws actually say, why an invisible grill sits on the right side of almost every rule, what a committee will ask for, and what to do if the answer is still no. It covers Mumbai, Thane, Navi Mumbai and Pune; Bangalore; and Delhi, Noida and Gurugram.

Quick answer: In almost every housing society an invisible grill is allowed, and often where welded grills are not. It involves no welding, no change to the facade colour or line, no enclosure of the balcony and no structural work, and it is fully reversible — so it falls outside the alterations the Bombay High Court's 2026 directive targets (brick walls, tin-sheet roofs, permanent enclosures). You still need to inform the committee and, in most societies, get a written no-objection. Your installer provides the one-page spec sheet; a request letter you can copy is below.

What changed in 2026

Hearing a dispute over a flat owner who had enclosed open terraces with brick walls and tin sheets, the Bombay High Court ordered the demolition of the unauthorised structures and directed the Maharashtra government to frame comprehensive guidelines on which alterations in individual flats are permissible — explicitly listing safety grills, balcony enclosures and lightweight coverings among the items the policy must address — and to create an online portal so permissions stop depending on a committee's mood. The court's point was that owning a flat does not mean unrestricted modification of a building other people live in.

That directive cuts both ways for grill buyers. It will eventually make the rules clear and the approval process online. Until the guidelines are published, societies in Maharashtra are being cautious about anything that looks like an "alteration", and some committees have paused approvals they would have waved through a year ago. The way through is to show that an invisible grill is not the kind of alteration the court was describing.

Why an invisible grill is on the right side of almost every rule

Society bye-laws and municipal rules object to balcony changes for five reasons. A cable grill clears all five.

This is why many societies that banned new welded grills after a facade dispute approve invisible grills on a one-page spec sheet — and why the National Building Code's own guard provisions (a barrier a 100 mm sphere cannot pass, at about 1.0–1.2 m height) are the standard the grill is designed to meet rather than violate.

City by city

Mumbai, Thane, Navi Mumbai, Pune

Cooperative societies run under the Maharashtra Cooperative Societies Act and the model bye-laws, which require members to seek the committee's permission for changes affecting the building's exterior. Pending the state guidelines the court asked for, treat a written NOC as mandatory. In practice Mumbai committees approve invisible grills readily because the alternative — residents fitting nets and MS grills piecemeal — is the facade problem they are trying to avoid. Towers with a builder-appointed facility manager (Lodha, Hiranandani, Godrej, Rustomjee estates) usually have a standard alteration form; tick "safety grill — non-welded, reversible" and attach the spec sheet.

Bangalore

Apartment owners' associations under the Karnataka Apartment Ownership Act tend to regulate by their own facade guidelines rather than statute. Glass-fronted towers in Whitefield, Sarjapur and Hebbal often prohibit "grills" in the bye-laws written for MS bars; the committee's concern is the look from outside. Show them a photo of an installed cable grill — most cannot find it in the picture — and ask for the prohibition to be read as applying to welded grills. "Is invisible grill allowed in Bangalore" has no statutory answer; it has an association answer, and it is usually yes once they see one.

Delhi, Noida, Gurugram

RWAs in DDA and private colonies, and AOAs in Noida and Gurugram towers, have no single rule set. Noida's builder-managed societies lean strict on facade uniformity; DDA flats lean permissive. The monkey problem in many NCR societies works in your favour — committees that have refused nets on facade grounds will approve a cable grill that solves monkeys, pigeons and child safety in one reversible install.

Gujarat

Covered in the Gujarat society rules guide: committees under the Gujarat Cooperative Societies Act and the Ownership of Flats Act are generally permissive on grills and increasingly restrictive on nets.

What the committee will ask for

• A spec sheet: material (SS316 cable, anodised aluminium track), gap (50 mm), fixing method (anchors into slab, no welding), colour, and the openable section. Your installer supplies it.

• A photo or drawing of the finished look from outside the building.

• Confirmation of no structural change and no enclosure — the two words to put in writing.

• Installer details and, in some towers, a deposit against facade damage, refunded after the facility manager inspects.

• Working hours — most societies allow drilling 10 am to 6 pm on weekdays.

A request letter you can copy

To: The Secretary / Managing Committee, [Society name]. Subject: Request for no-objection to install a non-welded safety grill on the balcony of Flat [number].

I request the committee's no-objection to install an invisible safety grill on my balcony. The system consists of 2 mm SS316 stainless-steel cables at a 50 mm gap, fixed between anodised aluminium tracks anchored to the slab, with one openable section lockable from inside for cleaning and emergency egress. There is no welding, no cutting of any structural member, no glazing or roofing, and no change to the building's facade line; the track colour matches the existing window frames. The installation is fully reversible. The purpose is child and pet fall-prevention in line with the National Building Code's guard provisions. Specification sheet and installer details are attached. I undertake to carry out the work between [hours] and to make good any incidental damage. Kindly confirm in writing. [Name, flat, date]

If the answer is still no

Ask for the refusal in writing with the bye-law clause it relies on — vague refusals often dissolve at that step. If the clause bans "grills" generically, request a committee visit to a flat with an installed invisible grill, or offer a reversible trial. If the committee is enforcing a builder-era facade covenant, check whether the covenant has expired with the handover to the society. As a last resort in Maharashtra, a member can approach the Deputy Registrar of Cooperative Societies; in Karnataka and Delhi, the registrar under the respective apartment acts. Most disputes do not get there: child safety is the one argument committees rarely want on the minutes as the thing they refused.

The bottom line

An invisible grill is allowed in almost every Indian housing society because it is not the alteration the rules were written against. Inform the committee, attach the spec sheet, put "no welding, no enclosure, fully reversible" in writing, and keep the NOC with your flat papers. The apartments and societies page has the per-flat pricing and the spec sheet committees are used to seeing.
