Legal Risks of Stilt Floor Conversions in Bangalore

What Legal Checks Are Needed When a Building’s Stilt Floor Has Been Converted to Habitable Space in Bangalore?

By the Property Law Team | Legal Brigade | Bar Council of Karnataka

When a Bangalore apartment building’s stilt floor — the open or semi-open ground-level floor that the BBMP building plan sanctioned specifically as a vehicle parking area and that was included in the building plan on the basis that it would remain open and unenclosed — has been partially or wholly enclosed by walls, windows and doors to create habitable rooms, office spaces, servant quarters, storage rooms or any other enclosed use, the enclosed stilt floor is an unauthorised change of use that violates the sanctioned building plan, consumes FAR that was not allocated to the stilt because it was intended as open parking and creates a BBMP enforcement risk for the entire building including the upper floor flats whose owners had no role in the enclosure.

What Is a Stilt Floor and Why Does BBMP Sanction It Differently From a Regular Floor?

A stilt floor in a Bangalore apartment building is a raised ground floor — typically one to three metres above natural ground level — whose primary structural purpose is to raise the building above the ground to allow vehicle parking beneath it on an open or semi-open level. The stilt floor’s columns support the building above while the space between the columns at the stilt level is left open or semi-open for parking. Because the stilt is not an enclosed habitable floor, BBMP’s building regulations do not include its area in the building’s FAR calculation and do not levy development charges on it as built-up habitable area.

The consequence of this differential treatment is that the stilt floor represents “free” building area from a regulatory standpoint — area that was not charged in development fees and was not counted against the FAR. When developers or residents enclose this area — adding walls, windows and doors to create enclosed rooms — they are converting a non-FAR area into effective FAR without the corresponding plan sanction or development charge payment. BBMP’s position is that the enclosed stilt area is an unauthorised FAR addition that must either be demolished and restored to open parking or must be regularised through a plan amendment and additional development charge payment — if regularisation is permitted under the applicable bye-laws.

How Does the Stilt Floor Enclosure Affect the Building’s FAR Compliance?

The stilt floor’s exemption from FAR calculation is conditional on it remaining open or semi-open for parking. Once the stilt is enclosed, the enclosed area effectively becomes FAR-consuming built-up area — but FAR was not allocated for it in the building plan and development charges were not paid for it. An enclosed stilt therefore creates a double FAR problem: the building has consumed FAR beyond what was sanctioned, and the development charge underpayment must be made up through the regularisation process.

The extent to which BBMP will permit regularisation of an enclosed stilt depends on the building’s remaining FAR headroom under the applicable bye-laws. If the building has already consumed its full permitted FAR through the sanctioned floors, there is no FAR headroom to accommodate the enclosed stilt area — making regularisation impossible and demolition the only option. If some FAR headroom exists, BBMP may permit regularisation on payment of a compounding fee and additional development charges.

How Do I Check Whether the Stilt Floor Is Properly Open Before Buying?

Step 1: Physically visit the building and inspect the stilt floor. Confirm that the stilt is open or semi-open for parking — that there are no permanent walls, enclosed rooms or commercial shutters that convert the stilt from parking to enclosed space.

Step 2: Obtain the BBMP-sanctioned building plan and confirm the stilt floor’s plan description — it should show open columns, parking bays and vehicle ramps without any enclosed rooms or walls between columns.

Step 3: Compare the building plan’s stilt floor layout against the physical stilt floor during your visit. Any enclosed area that does not appear in the plan is an unauthorised addition.

Step 4: Ask the association secretary whether BBMP has issued any deviation notice or show cause notice specifically referencing the stilt floor. A prior notice that was not complied with is a live enforcement risk.

Step 5: Have a property lawyer assess the stilt floor’s compliance position — confirming the plan description, the physical reality and any BBMP enforcement history — before any purchase commitment.

Frequently Asked Questions

Q1. What is a stilt floor and why is it treated differently from a regular apartment floor?

A stilt floor is the open or semi-open ground level of a building raised above natural ground on columns, specifically designed to allow vehicle parking beneath the building. Because the stilt floor is open rather than enclosed, BBMP’s building regulations do not count its area in the building’s FAR calculation and do not levy development charges on it. This differential treatment makes the stilt floor “free” area from a regulatory standpoint — which is why enclosing it to create habitable space is a violation of the plan condition under which the stilt was exempted from FAR.

Q2. Can the stilt floor be regularised if it has been enclosed?

Regularisation of an enclosed stilt floor depends on the building’s FAR headroom. If the building has FAR remaining under the applicable bye-laws, BBMP may permit regularisation of the enclosed area on payment of a compounding fee and additional development charges. If the building has already consumed its full permitted FAR through the sanctioned floors, regularisation is not possible — BBMP is obligated to direct demolition of the enclosed stilt area. The FAR headroom assessment requires a specific calculation based on the plot area and the applicable FAR for the zone.

Q3. Who is responsible for the stilt floor enclosure — the developer or the association?

Responsibility depends on when and how the enclosure occurred. If the developer enclosed the stilt floor before handover — either during construction or before the OC was obtained — the developer created the deviation. If the association or individual flat owners enclosed the stilt after the OC was obtained — either for storage, servant quarters or commercial use — the association is responsible for the post-OC deviation. In either case, BBMP’s enforcement action is directed at the building’s current owner and manager — the association — regardless of who created the deviation.

Q4. Does a stilt floor enclosure appear in the EC for the building?

A stilt floor enclosure is a physical building compliance deviation — it does not create an entry in the sub-registrar’s EC. The EC records registered documents such as sale deeds, mortgages and discharges — it does not record building plan deviations. The stilt floor compliance check requires a physical site visit and a building plan comparison — neither the EC review alone nor the Kaveri 2.0 search will reveal a stilt enclosure. This is why the physical inspection is an essential element of the building compliance check.

Q5. What happens if BBMP issues a demolition notice for an enclosed stilt in a large apartment building?

A BBMP demolition notice for an enclosed stilt requires the association to demolish the enclosing structures and restore the stilt to its sanctioned open parking condition. For a large building where the stilt has been extensively enclosed — with permanent walls, rooms and plumbing — the demolition and restoration is a significant and expensive project. The cost falls on the association. If the enclosed stilt generated rental income for the association, that income stream also ends. The disruption affects all flat owners during the demolition period.

Q6. Is a covered parking bay with a roof but open sides the same as an enclosed stilt?

A covered parking bay — with a roof over the stilt but open sides — is generally compliant with the stilt’s open parking designation because it remains open for ventilation and access. The critical element is enclosure — whether permanent walls create an enclosed interior space. A roof without walls preserves the stilt’s open character. A roof with solid walls creates an enclosed space that consumes FAR without a plan sanction. The specific treatment of covered-but-open stilt bays depends on the building plan’s specifications and BBMP’s assessment.

Q7. Can the individual flat owner use the parking bay in the stilt for purposes other than vehicle parking?

The stilt parking bay allocated to a specific flat is designated for vehicle parking under the building plan. Using it as personal storage, as a workshop or for any purpose other than vehicle parking is a use deviation. More seriously, enclosing the bay with walls or shutters to facilitate the alternative use is a building plan deviation. A flat owner who encloses their stilt parking bay risks both a BBMP show cause notice and a violation of the association’s bye-laws — which typically require stilt parking bays to be used only for their sanctioned purpose.

Q8. How does the stilt enclosure affect the building’s home loan eligibility for flats on upper floors?

A home loan bank whose technical valuer identifies a stilt enclosure may flag it as a building plan deviation. For upper floor flats, the enclosure does not directly affect their individual unit’s compliance — but it affects the building’s overall compliance status. Banks assessing risk for the entire building’s regulatory standing may be more cautious about lending on units in a building with a known unauthorised stilt enclosure. The severity of the bank’s concern depends on whether the enclosure is minor — a few storage cupboards — or major, such as a full commercial conversion.

Q9. What if the builder sold parking bays in the stilt as separately titled property?

Some developers sold stilt parking bays as independently titled units — with separate sale deeds for the parking bay area. A separately titled stilt parking bay that the owner subsequently enclosed to create habitable space is a more complex deviation — because the owner may argue they have the right to use their titled property as they choose. However, the building plan’s designation of the stilt as open parking is a use restriction that applies regardless of who holds title to the bay. The enclosure remains a BBMP deviation regardless of the ownership structure.

Q10. How does Legal Brigade check stilt floor compliance during property verification?

Legal Brigade’s building compliance check includes a physical inspection of the stilt floor during the site visit — confirming whether the stilt is open as sanctioned or whether any enclosure has occurred. Where an enclosure is identified, Legal Brigade checks the building plan for any plan amendment that may have sanctioned the enclosure, reviews any BBMP enforcement history and assesses the FAR headroom for regularisation. Legal Brigade advises the buyer on the enforcement risk and the regularisation prospects before any purchase commitment.
