Protect Your Dream Home from Legal Trouble
Did you know that thousands of homebuyers in cities like Chennai, Bengaluru, and Pune unknowingly invest in properties that are partially or fully illegal? A dream home without proper legal approvals can turn into your worst financial nightmare—fines, legal disputes, or even demolition.
Buying a property is often the biggest investment of your life, and a little due diligence today can save lakhs of rupees tomorrow. This guide will show you how to verify if a property is legally approved, step by step, so your investment is safe, secure, and worry-free.
What “Legally Approved for Construction” Really Means
A property is legally approved when local authorities give formal clearance for construction. This approval ensures the building is safe, follows rules, and is fit for habitation.
A legally approved property confirms:
- Zoning Regulations: The land is meant for residential, commercial, or industrial use.
- Building Codes & Bylaws: The structure adheres to safety, design, and construction standards.
- Safety Standards: Fire safety, earthquake resistance, and other safety measures are implemented.
- Environmental Norms: Construction does not harm the surrounding environment.
Think of it as a stamp of safety and legality for your home.
Why Legal Verification Is Non-Negotiable
Skipping legal verification can lead to:
- Demolition Risk: Illegal constructions can be torn down by authorities.
- Financial Loss: Banks may refuse home loans for properties with legal issues.
- Ownership Challenges: Difficulties in registering or selling the property later.
- Lack of Basic Amenities: No legal access to water, electricity, or sewage.
Now, let’s see the 8-step checklist to verify a property’s legal approvals.
The Ultimate 8-Step Legal Checklist for Property Buyers
1. Scrutinize the Title Deed & Ownership Chain
The Title Deed proves who legally owns the land.
What to check:
- Verify the Sale Deed in the developer’s name.
- Trace ownership history using the Mother Deed, sometimes going back 30 years.
- Ensure there are no disputes or claims.
How to verify:
- Hire a real estate lawyer for a title search at the local Sub-Registrar’s Office.
- Ask for an Encumbrance Certificate (EC) to ensure the property is free from loans or legal disputes.
Example: If a 750 sq ft plot in Kalavakkam shows a clear EC, you can safely move ahead with the purchase.
2. Verify the Building and Layout Plan Approval
No construction can legally begin without approval from local authorities like the Municipal Corporation or CMDA.
What to check:
- Compare the approved plan with the actual building.
- Ensure no extra floors, unauthorized extensions, or encroachments.
How to verify:
- Request a stamped copy of the approved plan from the developer.
- File an RTI with the local municipal office to confirm authenticity.
3. Demand Completion & Occupancy Certificates (CC & OC)
- Completion Certificate (CC): Confirms the building is constructed as per approved plans and codes.
- Occupancy Certificate (OC): Certifies the building is fit for living and has access to water, electricity, and sanitation.
Why it matters:
- Without OC, occupancy is illegal, utility connections may be denied, and registration becomes difficult.

4. Confirm Land Use Approval (Land Conversion)
Land is zoned for residential, commercial, industrial, or agricultural purposes. Building on agricultural land without conversion is illegal.
What to check:
- Ensure the land plot is zoned for residential use.
- For converted land, ask for Change of Land Use (CLU) approval.
How to verify:
- Check the city’s Master Plan at the local planning authority’s office or website.
5. Verify RERA Registration
The Real Estate (Regulation and Development) Act, 2016 (RERA) protects homebuyers.
What to check:
- Major projects over 500 sq m or 8 apartments must be RERA-registered.
- Ask for the project’s RERA registration number.
How to verify:
- Visit the state RERA website and search by project name, promoter name, or registration number.
Tip: Buying a non-RERA registered property where registration is mandatory is a red flag.
6. Check Environmental Clearance (EC)
Large projects (20,000 sq m or more) need clearance from the Ministry of Environment or SEIAA.
Why it matters:
- Ensures construction doesn’t harm water, air, or biodiversity.
- Projects without EC can face delays or legal action.
7. Verify Floor Space Index (FSI) Compliance
FSI/FAR limits how much construction can happen on a plot.
Formula:
What to check:
- Ensure the building does not exceed FSI limits.
- Excess construction is illegal and can lead to penalties or demolition.
Tip: Hire an architect or lawyer to verify FSI compliance against local rules.
8. Engage Professional Help
Even with all checks, professional guidance is invaluable:
- Real Estate Lawyer: Verifies legal documents, performs title search, drafts a sale agreement.
- Civil Engineer / Architect: Checks construction quality and compares it to approved plans.
Bottom line: Professionals help avoid costly mistakes

Frequently Asked Questions (FAQ)
1. What does it mean if a property is legally approved for construction?
A legally approved property has received all necessary permissions from local authorities, confirming that it follows building codes, zoning rules, safety standards, and environmental norms. This ensures your home is safe and lawful.
2. Why is checking the Title Deed important before buying a property?
The Title Deed proves ownership and the right to sell the property. Verifying it ensures there are no disputes, unpaid loans, or legal claims against the property.
3. What are Completion Certificate (CC) and Occupancy Certificate (OC)?
- Completion Certificate (CC): Confirms the building is constructed according to approved plans and safety standards.
- Occupancy Certificate (OC): Certifies the building is fit for living and has access to essential services like water, electricity, and sewage.
Without OC, occupying or registering the property can be legally problematic.
4. How can I check if a property has RERA registration?
Ask the builder for the RERA registration number and verify it on your state’s official RERA website. RERA registration ensures the developer has submitted all legal approvals and protects buyers from fraud.
5. What is Land Use Approval (CLU), and why is it important?
Land is zoned for specific purposes—residential, commercial, industrial, or agricultural. Change of Land Use (CLU) approval is required when converting land from one use (like agricultural) to another (like residential). Buying without CLU can make the property illegal.
6. How do I check if a property complies with Floor Space Index (FSI)?
FSI/FAR limits the maximum construction area on a plot. You can verify compliance by comparing the built-up area against the plot size using local development rules. A civil engineer or architect can assist in confirming this.
