The Real Estate (Regulation and Development) Act, 2016 (RERA) is a central law that created a common regulatory framework for India’s real estate sector. However, RERA is implemented through individual state and Union Territory authorities, and each jurisdiction has its own rules, regulations, procedures, forms and administrative practices.
As a result, Karnataka RERA (K-RERA) operates under the same central legislation as authorities such as MahaRERA in Maharashtra, UP-RERA in Uttar Pradesh and HRERA in Haryana, but there are differences in how certain provisions are implemented.
Karnataka notified its Karnataka Real Estate (Regulation and Development) Rules, 2017 in July 2017 and subsequently developed its own regulations and procedures. The Karnataka RERA framework therefore combines the central RERA Act with state-specific rules and regulations.
For property buyers and developers, understanding these differences is useful because registration requirements, disclosures, project definitions, fees, complaint procedures and digital services can vary between states.
What Is Karnataka RERA?
Karnataka RERA is the state’s implementation of the Real Estate (Regulation and Development) Act, 2016.
The authority regulates eligible real estate projects and agents, publishes project-related information and provides a mechanism through which eligible complaints can be filed against promoters and real estate agents.
According to Karnataka RERA’s annual report, the authority is responsible for protecting the interests of consumers and providing a legal forum for complaints and redressal against developers and agents. The report also notes that projects meeting the applicable threshold of at least 500 square metres or eight or more residential units, where construction is ongoing and the required completion certificate has not been obtained, are subject to registration under the applicable framework.
1. Karnataka Has Its Own State-Specific Rules
The most important point is that Karnataka does not operate solely on the text of the central RERA Act.
The Karnataka Real Estate (Regulation and Development) Rules, 2017 provide additional requirements for project registration, ongoing projects, real estate agents and disclosures.
For example, Karnataka’s registration rules require promoters to provide additional information including the promoter’s PAN, financial information, number of parking slots and title-related documents. They also require details concerning encumbrances and certain land-use and conversion permissions where applicable.
Other states have their own rules.
For example, Haryana has the Haryana Real Estate (Regulation and Development) Rules, 2017, which prescribe additional registration information and documentation, including financial information concerning the promoter.
This means a developer operating in Karnataka and another developer operating in Haryana may have to provide different forms or additional disclosures even though both are complying with the same central RERA legislation.
2. Karnataka’s Definition of Ongoing Projects Has Specific Exclusions
One notable feature of Karnataka’s rules is the detailed treatment of ongoing projects.
Karnataka Rule 4 defines an ongoing project as one where development is continuing and a completion certificate has not been issued, but it excludes specified situations.
These include certain projects where:
- Streets and civic amenities have been handed over to the relevant authorities.
- Common areas and facilities have been handed over to an association of allottees.
- Development has been completed and 60% of the relevant sale or lease deeds have been registered.
- Development has been completed and an application for a completion or occupancy certificate has been filed.
- A partial occupancy certificate has been obtained for the relevant portion.
The details matter because whether a project falls within the applicable registration framework can depend on its status under the relevant state rules.
Maharashtra also has specific provisions concerning ongoing projects, but its rules and administrative interpretation are not identical to Karnataka’s. MahaRERA’s FAQ, for example, discusses ongoing projects by reference to buildings or phases that have not received the relevant occupancy or completion certificates.
3. Karnataka Requires Detailed Project Disclosures
Karnataka’s rules place emphasis on project-level disclosures.
For ongoing projects, the rules require promoters to disclose information including the original sanctioned plan, layout plan and specifications, subsequent modifications, money collected from allottees, money used for development and the status of construction.
The promoter must also disclose the original completion timeline and the proposed period for completing pending work, with the relevant status information certified by an engineer, architect and chartered accountant.
This provides buyers with information that can be useful when evaluating an older or delayed project.
MahaRERA similarly requires extensive project information to be made available online and states that project information submitted at registration generally cannot simply be edited, although progress-related fields can be updated.
Therefore, both authorities emphasise transparency, but the specific disclosure requirements and online workflows differ.
4. Karnataka’s Registration Fees Follow a State-Specific Structure
RERA project-registration fees are not identical across India.
Under Karnataka’s 2017 rules, registration fees for projects were linked to factors such as project type and land area, with separate rates for group housing, mixed development, commercial projects and plotted development, subject to specified maximum amounts.
For example, the rules provide different per-square-metre rates and maximum limits depending on whether the project is group housing, mixed development, commercial or plotted development.
This contrasts with other states where fee structures may use different categories or calculations.
Consequently, developers operating across multiple states need to check each state’s current fee schedule rather than assuming that one RERA fee structure applies nationally.
5. Karnataka Has Its Own Interest and Regulatory Framework
The central RERA Act establishes rights relating to interest, refunds and compensation, but state rules can prescribe specific rates and procedures.
Karnataka’s rules have historically prescribed a formula for interest under Section 18. Karnataka’s later regulatory framework also includes the Karnataka RERA General Regulations, 2022, which govern matters within the authority’s jurisdiction.
This is important because a buyer seeking interest on a refund or compensation may need to examine the Karnataka rules and regulations applicable to the particular dispute rather than relying only on the wording of the central Act.
Other authorities have their own regulations and procedures for implementing similar statutory rights.
6. Complaint and Online Services Can Differ
All RERA authorities operate within the broader statutory framework, but the digital interface and complaint-management process can differ.
Karnataka provides online services through its RERA system, including facilities for tracking complaints. The National Government Services Portal describes Karnataka’s complaint-status service as fully online, allowing complainants to track actions, hearing schedules and resolutions.
UP-RERA has also developed a significant digital ecosystem. Its current portal publishes regulatory updates, orders, general regulations and other project-related information.
MahaRERA likewise operates a detailed online registration and disclosure system, with FAQs explaining project registration, ongoing projects and promoter disclosures.
The practical experience of filing a complaint, uploading documents, tracking proceedings or obtaining orders can therefore vary by state.
7. Karnataka’s Regulatory Structure Is Different From Haryana’s
Another important difference concerns the number and structure of regulatory authorities.
The central RERA Act permits a state to establish more than one authority where appropriate. Haryana, for example, has two RERA authorities: one for Gurugram and another for the rest of Haryana.
Karnataka, by contrast, has a state-level Karnataka Real Estate Regulatory Authority.
This distinction matters because the relevant authority in Haryana depends partly on the property’s location, while a Karnataka project falls within the Karnataka RERA framework.
8. MahaRERA Has Its Own Detailed Phase-Based Framework
Maharashtra is another useful comparison because of the scale of its real estate market.
MahaRERA’s rules and FAQs specifically address the concept of a phase of a project. Its guidance states that registration is undertaken for the project or phase and that the provisions of RERA apply to the registered project or phase.
MahaRERA also has detailed rules and regulations concerning project registration, agents, interest rates, website disclosures, complaints and appeals.
Karnataka also regulates project phases and registrations, but its state rules contain their own definitions, disclosure requirements and procedures.
Therefore, developers and buyers should not assume that a project structure accepted in Maharashtra will automatically receive identical treatment in Karnataka.
9. What Does This Mean for Property Buyers?
For buyers, the main lesson is that RERA registration should always be checked on the relevant state authority’s portal.
If buying property in Karnataka, examine the K-RERA registration and available project disclosures.
A buyer should check:
- RERA registration number
- Promoter details
- Land ownership information
- Encumbrances
- Approved plans
- Project completion date
- Construction progress
- Number of units
- Carpet area
- Project approvals
- Complaints and orders, where available
- Extensions or changes to registration
A buyer should also read the agreement for sale carefully and conduct independent title and property due diligence.
Karnataka RERA vs Other State RERA Authorities
| Factor | Karnataka RERA | Other State Authorities |
| Governing law | Central RERA Act + Karnataka Rules/Regulations | Central Act + respective state rules/regulations |
| Ongoing projects | Karnataka-specific exclusions and disclosures | Definitions and exclusions vary |
| Registration fees | Karnataka-specific fee structure | State-specific fee structures |
| Project disclosures | Karnataka-prescribed disclosures | Different forms and disclosure requirements |
| Complaint process | Karnataka-specific online and administrative process | Varies by state |
| Interest implementation | Governed by Act plus Karnataka rules/regulations | State rules/regulations may differ |
| Authority structure | State-level K-RERA | Some states have different structures |
| Digital services | Karnataka-specific portal and services | Portal features vary |
Conclusion
Karnataka RERA is based on the same Real Estate (Regulation and Development) Act, 2016 that applies across most of India’s states, but its implementation is shaped by Karnataka’s own rules and regulations.
The differences can be seen in the treatment of ongoing projects, registration documentation, project disclosures, registration fees, interest provisions, complaint procedures and digital services. Karnataka’s rules also contain detailed requirements concerning title documents, encumbrances, land-use permissions and project-status disclosures.
Other authorities have developed their own frameworks. Maharashtra’s MahaRERA has detailed phase-based registration and disclosure procedures, while Haryana operates two separate RERA authorities based on geographic jurisdiction.
For property buyers, the practical approach is to treat RERA as a state-specific regulatory system built on a common central law. Before purchasing a property, buyers should check the relevant state RERA portal, review project disclosures, examine the registration status and verify the property’s title and approvals independently.
Understanding these state-level differences can help buyers interpret RERA records more accurately and avoid assuming that procedures or requirements in one state automatically apply to another.
