How to read Bengaluru by-laws before designing

A plot dimension does not reveal the buildable envelope. Start with the exact parcel, current authority and current regulation set.

Educational orientation only. Regulations, notifications, court outcomes, authority boundaries and procedures can change. The competent authority and sanctioned documents govern the actual project.

01 · Jurisdiction

Identify the authority before the rule.

Confirm the plot's current city corporation, planning authority, layout or development authority, and any special agency. Greater Bengaluru's governance transition means older pages and documents may still use BBMP terminology. A portal or map view is a starting point, not a sanction opinion.

  • Survey number and property identifiers
  • Current ward and city corporation
  • Planning and sanctioning authority
  • Approved layout or conversion status
  • Special airport, defence, lake, drain or infrastructure control

02 · Envelope

Check all variables together.

Read permitted use, road width, road widening or building line, plot area and frontage, setbacks, FAR, height, ground or stilt conditions, parking, dwelling-unit limits, fire access, basement controls and service requirements as one system. Do not copy a setback or FAR from a different ring, road or plot.

  • Land use and permitted occupancy
  • Recorded and physical road width
  • Plot band and building height
  • Setbacks and projections
  • FAR or premium/TDR route
  • Parking and vehicle access
  • Rainwater, sewer and other service conditions

03 · Current amendment

Date every numerical rule.

Government Notification UDD 235 MNJ 2025(E), dated 5 January 2026, amended Greater Bengaluru RMP-2015 zonal regulations including setback Table 8. It applies to new work and specified modification or ongoing proposals requiring approval. A current project must still verify later notifications, its height band and parcel-specific conditions before using any number.

04 · Approval record

Keep submission, sanction and site aligned.

Maintain the application, ownership and khata records, signed drawings, calculations, NOCs, fee receipts, queries, revised submissions and sanction. During work, record plinth or stage inspections and approved changes. Before use, confirm the applicable completion and occupancy route rather than assuming construction completion is enough.

  • e-Khata and property records where required
  • Signed sanctioned set
  • Authority queries and responses
  • Revised or modified approval
  • Plinth, completion and occupancy records
  • As-built deviations and legal review
