Penalties and Consequences of Unauthorised Development: Your Shield Against Illegal Property in India

Owning a home in India is a big dream for many people. It gives a sense of pride and security. But sometimes, a small mistake like building something without permission can cause big problems.
In cities like Mumbai, many buildings face trouble because of unauthorised development, which means building or changing something without legal approval.

This simple guide will help you understand what unauthorised development means, what happens if it’s ignored, and how you can fix it to keep your property safe.

What is Unauthorised Development?

Unauthorised development means building, changing, or using land without official permission from the local authority (for example, the BMC in Mumbai).

It’s not always a big illegal project even small changes can count. For example:

• Adding an extra floor or balcony that’s not in the approved plan.
• Making big changes to the building’s structure.
• Using land meant for homes as shops or offices.
• Ignoring the allowed building limits (FSI/FAR).

Many people only realise something is wrong when they get a stop work notice or a demolition order. These problems happen when people skip legal steps meant to keep buildings safe and cities well-planned.

What Happens If You Build Without Permission?

The law takes illegal construction very seriously. The Maharashtra Regional and Town Planning (MRTP) Act, 1966 gives authorities the power to act quickly. The results can be harsh you can lose money, property, and peace of mind.

1. Stop Work and Demolition

If the authority finds unauthorised work:

• They’ll send a stop work notice you must stop construction right away.
• If you ignore it, it becomes a criminal offence.
• In serious cases, they can demolish the illegal part of the building, and you’ll have to pay the cost.

2. Big Financial Penalties

Building without approval can get very expensive.

• 200% Property Tax Fine: In Mumbai, the BMC can charge double property tax until your building becomes legal.
• Daily Fines: You’ll pay extra every day until the mistake is fixed.
• No Loan or Sale: Banks won’t give you a loan, and you can’t legally sell or transfer the property.

3. Legal and Safety Issues

• Criminal Charges: Both the owner and the builder can face fines or even jail time.
• Loss of Basic Services: Authorities can cut your water and electricity.
• No Occupancy Certificate: Without it, you can’t legally live in or rent the building.
• No Insurance Cover: If something goes wrong, your insurance may not cover it.

So, illegal construction can lead to huge losses financial, legal, and emotional.

How to Fix the Problem The Regularisation Process

If you already have unauthorised construction, don’t worry there is a legal way to fix it. This process is called regularisation. It makes your property legal after checking safety rules and paying certain fees.

Step 1: Get a Professional Check-Up

Start by hiring an architect and a legal expert who understand local rules. They’ll check your property and tell you if it can be regularised.
Some problems, like unsafe structures or missing fire safety space, can’t be regularised.

Step 2: Check for Government Schemes

Sometimes, the government announces special regularisation schemes to help people fix old unauthorised buildings.
If one is open, apply quickly.
Collect your documents like:

• Sale deed
• Old building plan
• Property tax bills
• Electricity or water bills

Step 3: Apply for Regularisation

Once you know your property is eligible:

• The architect will prepare “As-Built” drawings, showing your current structure.
• A structural engineer will confirm that the building is safe.
• Submit your application and pay the required regularisation fee.

Make sure your paperwork is complete so it doesn’t get rejected.

Step 4: Get Your Regularisation Certificate

After the authority checks everything and you’ve paid all dues, you’ll get a Regularisation Certificate.
This is your official proof that your property is now legal and safe.

It protects you from future demolition, restores your property’s full value, and lets you sell or redevelop it legally.

For NRIs and Housing Societies

1. NRIs: Handling It From Abroad

If you’re an NRI, you can still manage the process easily.

• Give a Power of Attorney to a trusted real-estate or legal firm like LawCrust Realty.
• Always check a builder’s RERA registration, approved plan, and Occupancy Certificate before investing.

2. Housing Societies: Before Redevelopment

Many old housing societies in Mumbai can’t start redevelopment because of past unauthorised changes.

• Regularise first: Fix all old issues before signing a redevelopment deal.
• Stay compliant: Builders and RERA approvals need a clear legal record.

This saves time, avoids legal trouble, and helps your society get a fair redevelopment deal.
