The Maharashtra government has tightened property registration rules to prevent the sale of unauthorised flats and buildings. The decision could have significant implications for homebuyers, developers and property transactions across Mumbai, Pune, Thane and other parts of the state.
Maharashtra Introduces Stricter Property Registration Rules
Buying a home is one of the biggest financial decisions for most families. However, purchasing a flat in an unauthorised building can expose buyers to legal disputes, financial losses and even the risk of demolition.
To address these concerns, the Maharashtra government has directed Sub-Registrars across the state to stop registering property documents associated with unauthorised constructions and flats that violate approved building plans.
The Revenue Department issued a circular on October 12, 2026, outlining stricter verification requirements for property registration. The decision follows complaints involving illegal construction, residential buildings developed in unauthorised zones, projects operating without mandatory MahaRERA registration and flats being sold with areas exceeding sanctioned plans.
Revenue Minister Chandrashekhar Bawankule said the objective is to protect homebuyers from losing their savings in properties that do not comply with construction regulations
What Has Changed Under the New Rules?
The new guidelines require Sub-Registrars to verify prescribed construction approvals and supporting documents before registering certain property transactions.
The restrictions particularly affect the first sale of flats in projects where mandatory documents are missing or where the property differs from its approved construction plan.
Documents affected can include agreements for sale, sale deeds, apartment deeds and transfer deeds, depending on the applicable provisions.
One important requirement concerns the actual area of the flat. If the area mentioned in the sale agreement exceeds the area approved by the planning authority, the Sub-Registrar has been instructed not to register the transaction.
For example, if a developer has approval for a 700 sq. ft. flat but attempts to sell it as an 850 sq. ft. unit without the necessary approvals, the registration could be refused.
This is intended to prevent developers from selling additional or unauthorised construction as legally approved property.
Which Documents Must Developers Provide?
The government’s guidelines distinguish between projects requiring MahaRERA registration and those exempt from it.
| Projects requiring MahaRERA registration | Projects exempt from MahaRERA registration |
|---|---|
| MahaRERA registration certificate | Commencement certificate |
| Occupancy certificate | Sanctioned building plan |
| Sanctioned building plan | Zone certificate |
| Measurement map |
These are the documents identified in the reported guidelines. Their application to a particular transaction should be checked against the government circular and applicable law.
What Happens to Flats in Unauthorised Buildings?
The restrictions extend beyond properties that have been constructed entirely without permission.
They may also affect buildings that violate development plans, zoning regulations or the Unified Development Control and Promotion Regulations (UDCPR).
For instance, a developer may receive permission to construct a building with a particular number of floors but subsequently add unauthorised floors. Flats within such developments could encounter registration difficulties.
According to the government guidelines, buildings with violations that can legally be corrected must undergo the prescribed regularisation process before the affected transactions can proceed.
Structures that cannot be regularised may face demolition proceedings under applicable law.
However, not every building with a documentation issue is automatically illegal or subject to demolition. The nature of the violation, available approvals and legal provisions will determine the outcome.
Why This Matters for Mumbai, Thane and Pune
The decision is particularly relevant to Maharashtra’s rapidly developing urban property markets.
Complaints involving unauthorised construction have been reported across the Mumbai Metropolitan Region, Thane, Pune, Pimpri-Chinchwad, Haveli, Mulshi and Nagpur.
In high-demand residential markets, buyers may encounter projects offering comparatively affordable flats, additional space or attractive payment plans. However, lower prices do not necessarily mean a property has received all the necessary construction approvals.
For buyers considering apartments in developing suburbs, verifying the property’s legal status is therefore as important as evaluating its price, location and amenities.
The new registration requirements could increase scrutiny of developers operating in these markets and make compliance documentation a more important part of property transactions.
How Will the Decision Affect Homebuyers?
For prospective buyers, the biggest potential benefit is an additional level of scrutiny before certain property transactions are registered.
Previously, buyers could mistakenly assume that the registration of a sale deed established that the underlying construction was legal. In reality, registration and building approval are separate matters.
The government’s decision aims to reduce this risk by requiring officials to examine prescribed construction documents.
However, buyers may also face delays or complications when purchasing flats in buildings with missing approvals or discrepancies in sanctioned plans.
People who have already paid booking amounts for such properties could encounter difficulties completing registration until the relevant issues are resolved.
Importantly, registration approval should not be treated as a complete guarantee of a property’s legal status. Buyers must still conduct independent due diligence.
What Should Property Buyers Check Before Investing?
Before purchasing a flat in Maharashtra, buyers should verify the following:
- MahaRERA registration: Check whether the project requires registration and verify its details through the official MahaRERA website.
- Approved building plan: Confirm that the flat, floor and building layout match the sanctioned drawings.
- Commencement certificate: Verify that the relevant construction permissions have been issued.
- Occupancy certificate: For completed properties, check whether the required occupancy approval is available.
- Flat area: Compare the area mentioned in the agreement with the sanctioned plan, using consistent area measurements.
- Land use and zoning: Ensure that the development complies with the applicable planning regulations.
- Legal title: Have a qualified property lawyer examine ownership documents, encumbrances and relevant approvals.
These checks can help identify potential risks before buyers make substantial financial commitments.
What Does This Mean for Real Estate Developers?
Developers may now face greater pressure to maintain accurate and complete documentation throughout the construction and sales process.
Projects with unauthorised extensions, discrepancies in flat areas or missing mandatory approvals could encounter registration difficulties.
The guidelines also introduce accountability for registration officials. Sub-Registrars who deliberately register documents involving unauthorised constructions in violation of the circular may face departmental inquiries.
This could encourage closer coordination between developers, planning authorities and registration offices, while increasing the importance of regulatory compliance in residential sales.
Could the New Rules Face Legal Challenges?
Although the government’s objective is to protect homebuyers, questions have also been raised about the legal basis of the restrictions.
A techno-legal consultant quoted by The Times of India argued that an executive circular cannot override statutory registration requirements and questioned whether registration could be refused solely because certain building documents are unavailable.
This is a reported legal opinion, not a court ruling invalidating the circular.
The precise scope and enforceability of the guidelines may therefore require further clarification, particularly for older buildings, resale transactions and properties with longstanding approval disputes.
Will This Improve Transparency in Maharashtra’s Property Market?
The government’s decision could strengthen buyer confidence by making construction approvals a more visible part of the registration process.
It may also discourage developers from marketing flats that exceed sanctioned plans or selling properties without mandatory permissions.
However, the effectiveness of the policy will depend on consistent implementation, accurate verification of documents and clear procedures for dealing with existing buildings.
For the real estate industry, the development reinforces a broader principle: regulatory compliance is essential to protecting buyers and supporting a more transparent property market.
Conclusion
Maharashtra’s decision to restrict registration of unauthorised flats and buildings marks an important development in the state’s efforts to address illegal construction and property-related fraud.
For homebuyers, the message is clear: a property’s price, location and amenities should never outweigh the importance of legal approvals.
For developers, the new requirements highlight the need to ensure that projects comply with sanctioned plans and applicable regulations before selling flats.
As the guidelines are implemented across Maharashtra, their impact on property transactions, buyer protection and the treatment of existing unauthorised buildings will be important to monitor.
Ultimately, buying a home should begin with verifying the property, not just choosing the location.
