| Buildings > 18 m height → Governed by NBC Part 3, Table 6, requiring significantly larger all-round setbacks (e.g., 16 m for a 50 m tall building). | |
| Small residential plots (≤ 300 m²) → Setbacks may be relaxed as per local DCRs, a common provision for affordable housing and plots in older city areas. | |
| Corner plots → Front setback is required on all abutting roads as per NBC Part 3, Clause 7.2.1, Note 4. | |
| Projections into setback → Balconies, canopies, and sunshades may project into the setback area, subject to dimensional limits specified in local bye-laws or NBC Part 3, Clause 7.4. | |

Front setbacks ensure adequate natural light and ventilation for buildings, a primary goal of the NBC. This open space is critical for fire safety, allowing access for fire tenders, and also provides a buffer from street noise and pollution. It reserves land for potential future road widening by municipal authorities.
While these NBC values are a model code, the legally binding setbacks are defined in the Development Control Regulations (DCR) or building bye-laws of the local authority (e.g., Mumbai's DCPR, Delhi's MPD). These local rules may have different values and will override the NBC.
