Question 1

Can I build anything on a plot within 100 metres of an ASI-protected monument in Bengaluru?

Accepted Answer

No. The prohibited area extends 100 metres from the protected limit of any centrally protected monument. No construction of any kind is permitted in this zone, including boundary walls. The 100 m is measured from the notified protected limit of the monument as declared under the AMASR Act — not from the visible outer wall, fence, or perimeter of the site as it appears on the ground. The 100 m is measured from the notified protected limit of the monument as declared under the AMASR Act — not from the visible outer wall, fence, or perimeter of the site as it appears on the ground.

Question 2

What rules apply in the regulated area, 100 to 300 metres from the monument?

Accepted Answer

Construction in the regulated area (100–300 m) requires prior approval from the National Monuments Authority (NMA), routed through the Competent Authority (CA) — typically the State Director of Archaeology. Applications must be submitted to the CA, who forwards them to NMA within 15 days; NMA decides within two months. The approval requirement applies to all new construction, reconstruction, and repairs. Applications go through NMA’s NOAPS portal at nma.gov.in (mandatory since 1 July 2025 under the AMASR Amendment Act 2010). No construction should begin without written NMA approval in hand.

Question 3

Does proximity to a heritage site affect building height even outside the regulated zone?

Accepted Answer

Yes. Any plot within 500 metres of an ASI monument in Bengaluru is subject to height restrictions under BDA's buildability rules, even if it falls outside the 300-metre regulated area.

Question 4

What is a Heritage Impact Assessment and when is it required in Bengaluru?

Accepted Answer

A Heritage Impact Assessment (HIA) documents how a proposed construction affects a monument’s setting and character. NMA may require an HIA as part of the NOC application for regulated-area projects (100–300 m), with thresholds set by monument-specific Heritage Bye-Laws and project type. The HIA is submitted to the Competent Authority (CA), who forwards it to the National Monuments Authority (NMA) for review. NMA uses the HIA to assess whether the proposed project will cause adverse impact on the monument’s heritage value before granting or refusing permission. Verify the specific requirement for each Bengaluru monument with NMA before applying.

Question 5

What documents confirm a plot near Devanahalli Fort is legally buildable?

Accepted Answer

Confirm A-Khata status, DC conversion from agricultural to residential use, BIAAPA layout approval (Devanahalli falls under BIAAPA jurisdiction), and a written confirmation that the plot is beyond 300 metres from the boundary of every ASI monument in the vicinity (Devanahalli Fort and Tipu Sultan’s Birth Place). All four must be present.

Question 6

What happens if someone has already built in the prohibited zone?

Accepted Answer

The Central Government may order the owner to demolish the structure within a specified period. If they refuse, the government can demolish it and recover the cost from the owner.

Question 7

Can existing structures inside the prohibited zone be repaired or renovated?

Accepted Answer

Repairs and renovation within the prohibited area require prior permission from the National Monuments Authority (NMA). No work, including minor renovation, should begin without that written clearance.
