Neighbour’s illegal construction or building plan violation in India — how to complain to the municipal corporation or development authority, get the sanctioned plan by RTI, stop-work and demolition notices (e.g., Delhi DMC Act ss.343–344, Maharashtra MRTP Act ss.52–54), Supreme Court rules on notice before demolition (2024), civil injunction, and High Court writ if officials do not act (2026)
Plain map for residents worried about an unauthorised floor, encroaching wall, commercial use in a residential building or construction without approval next door — and for owners who receive a notice: who regulates buildings (municipal body, development authority, panchayat); getting the sanctioned plan and records by RTI; writing an effective complaint; what notices the authority can issue, with State examples; the Supreme Court’s November and December 2024 directions on unauthorised construction and demolition procedure; when a civil suit or injunction is the better route; escalation by appeal, RTI and writ; and what to do if you receive a notice.

Who regulates construction where you live
Building permissions are given and enforced under State laws: municipal corporation and municipality Acts, town and country planning Acts, development authority laws and building bye-laws; in villages, panchayat laws. Depending on the area, the authority may be the municipal corporation’s building department, a development authority (such as the Delhi Development Authority), an industrial development authority, a cantonment board or the gram panchayat. First identify which body sanctions plans for the plot — the answer decides where your complaint goes.
Is it really ‘illegal’? Common types of violation
Typical violations include: construction with no sanctioned plan; extra floors or height beyond the plan; covering setbacks or open space; projections over public land or a common passage; change of use (for example shops or a hotel in a residential plot); unsafe structural changes; and occupying a building without a completion or occupancy certificate. Not every change is illegal — some minor deviations can be compounded (regularised on payment) under local rules. A building being uncomfortable for you is not, by itself, a violation.

Step 1 — get the facts and documents
File an RTI application with the authority asking for: a copy of the sanctioned building plan and permission for the plot; inspection reports; any completion or occupancy certificate; notices already issued; and the action taken on earlier complaints. (The RTI application tool on Adhiwakta can help with the format.) Meanwhile take dated photos and videos from your own property or a public place — do not trespass — and note dates when work was done.
Step 2 — a clear written complaint
Address the complaint to the officer in charge of building control (for example the Executive Engineer (Building) or the ward / zone office) with a copy to the Commissioner or Vice-Chairman. Give the exact address and plot number; describe each violation precisely; attach photos and the RTI replies; say how it affects you (light, air, safety, blocked access, structural risk to your wall); and ask for inspection, a stop-work notice while work is ongoing and action under the applicable law. Many cities accept online complaints through their portals or apps. Keep the acknowledgement or complaint number and follow up in writing.
What the authority can do — State examples
Each law has its own sections and timelines. For example, under the Delhi Municipal Corporation Act, 1957 the Commissioner can order demolition of unauthorised construction after a show-cause opportunity (Section 343) and can stop ongoing work (Section 344), and appeals against such orders go to the Appellate Tribunal MCD (Section 347B). Under the Maharashtra Regional and Town Planning Act, 1966, unauthorised development is an offence (Section 52), the planning authority can serve a removal notice (Section 53) and a stop-work notice (Section 54). Other States have similar provisions in their own Acts — check the law and bye-laws that apply to your city.
What the Supreme Court said in 2024
In Rajendra Kumar Barjatya v. U.P. Avas Evam Vikas Parishad (17 December 2024) the Supreme Court said construction in violation of the approved plan cannot be protected because of delay, the money invested, or official inaction; and directed, among other things, that the approved plan be displayed at the site during construction; that completion or occupancy certificates be issued only after inspection; that electricity, water and sewer connections be given only after such a certificate; that no trade licence be given in unauthorised buildings; that banks verify the certificate before lending; that officials responsible be proceeded against; that regularisation schemes be only exceptional; and that applications about completion certificates or regularisation be decided within 90 days. Separately, in In Re: Directions in the matter of demolition of structures (13 November 2024), the Court required a prior show-cause notice (returnable in the time under local law or 15 days, whichever is later) served by registered post and affixed on the structure, a personal hearing, a reasoned final order, 15 days before implementation, and videography of demolition — except for unauthorised structures in public places such as roads, footpaths, railway lines and water bodies, or where a court has ordered demolition.
Step 3 — if the authority does not act
Write to the next senior officer with your complaint number and dates; use RTI to find out what action was taken and by whom; and use the State’s grievance portal or CPGRAMS-type system where available. If a statutory duty is clearly not being performed despite representations, a writ petition (mandamus) in the High Court asking the authority to decide your complaint in accordance with law is a common route — see the writ petition guide. Courts usually direct the authority to act after hearing the owner, rather than ordering demolition themselves.
Civil remedies against the neighbour
If the construction affects your own legal rights — encroachment on your land or wall, blocking an easement such as a right of way, or (in some cases) a long-enjoyed right to light and air (a prescriptive easement after 20 years under Section 15 of the Indian Easements Act, 1882) — you can consider a civil suit for a permanent or mandatory injunction (Sections 38 and 39 of the Specific Relief Act, 1963) and a temporary injunction while the suit is pending (Order XXXIX CPC). Act quickly: courts are reluctant to stop a building that is already complete. See the temporary injunction and land encroachment guides.
Flats and societies
If a builder has added unauthorised floors or changed the sanctioned plan in a registered real estate project, the State RERA can be approached under the RERA Act, along with the planning authority. Disputes about alterations by a member inside a housing society may also go to the society and the cooperative registrar. See the RERA and society / RWA guides.
If you received a notice for your own building
Read the notice for the specific violation, the documents asked for and the hearing date. Reply within time with your sanctioned plan, permissions, tax receipts and photos; ask for a personal hearing; explore compounding of minor deviations under local rules; and note the appeal remedy and its time limit. Under the Supreme Court’s 2024 directions, a demolition order should state why compounding or partial demolition is not possible and should not be implemented for 15 days from receipt. Do not continue construction after a stop-work notice.
What this guide is not
It does not tell you whether a particular construction is illegal or what action an authority will take. Building laws, bye-laws, compounding limits and appeal forums differ by State and city — check your local rules.

Frequently asked questions
- How do I complain about my neighbour’s illegal construction?
- Find out which authority sanctions plans in your area, get the sanctioned plan by RTI, then file a written or online complaint to the building department with the address, specific violations and dated photos, asking for inspection and a stop-work notice. Keep the complaint number and follow up in writing.
- How can I check whether a building has an approved plan?
- File an RTI application with the municipal body or development authority asking for the sanctioned plan, permissions, inspection reports and any completion or occupancy certificate for the plot.
- What if the municipal corporation takes no action on my complaint?
- Escalate to senior officers with your complaint number, use RTI to find out the action taken, and use the State grievance portal. If a legal duty is still not performed, a writ petition (mandamus) in the High Court is a common route.
- Can the authority demolish a building without notice?
- Under the Supreme Court’s 13 November 2024 directions, demolition needs a prior show-cause notice (local-law time or 15 days, whichever is later), a personal hearing, a reasoned order and 15 days before implementation — except for structures in public places like roads, footpaths, railway lines or water bodies, or where a court has ordered demolition.
- Can old illegal construction be regularised because a long time has passed?
- Delay, investment or official inaction do not protect violations, the Supreme Court said in December 2024; regularisation schemes should be exceptional. Some minor deviations may still be compounded under local rules.
- Can I file a civil case to stop my neighbour’s construction?
- If it affects your own rights — encroachment, blocked passage or, in some cases, an established right to light and air — a suit for injunction (Specific Relief Act ss.38–39) with a temporary injunction under Order XXXIX CPC may be possible. Act quickly, before construction is complete.
- Does Adhiwakta file complaints against illegal construction?
- No. Adhiwakta does not file complaints or RTI applications or contact anyone. Use Ask Adhiwakta or the AI helper for general educational guidance only.
