Projections allowed in Front and Side Margin as per UDCPR 2020

Mar 08, 2024

For the construction of any building, there is a restriction of floor space to be used. It is called the FSI (Floor space Index). Also, we have to provide distance from the plot boundary which is called as marginal distance or setbacks.


UDCPR 2020 Chapter 6 is all about Regulations for FSI & Marginal distance.


This is Applicable to all Planning Authorities and Regional Plan Areas except the Municipal Corporation of Greater Mumbai, Other Planning Authorities/Special Planning Authorities/Development Authorities within the limit of Municipal Corporation of Greater Mumbai, MIDC, NAINA, Jawaharlal Nehru Port Trust, Hill Station Municipal Councils, Eco-sensitive/Eco-fragile region notified by MoEF & CC and Lonavala Municipal Council, in Maharashtra.




The following projections shall be permissible in marginal open spaces :-


(a) Projections into Marginal Open Spaces :- Every open space provided, either interior or exterior, shall be kept free from any erection thereon and shall be open to the sky, and no cornice, chajja, roof, or weather shade more than 0.75 m. wide shall overhang or project over the said marginal open spaces so as to reduce the width to less than the minimum required. However, sloping / horizontal chajja provided over balcony/gallery, etc., may be permitted up to balcony projections at a horizontal level.


(b) Balconies - as specified in Regulation No.9.14

(c) Ledge for Air conditioning unit as specified in Regulation No.9.5.

(d) A canopy or porch not exceeding 5 length and 2.5 m. in width in the form of a cantilever and unenclosed over the main and subsidiary entrances providing a minimum clear height of 2.4 m. below the beam bottom of the canopy. The canopy shall not have access from the upper floors (above floors), for use as a sitting out place. There shall be a minimum clearance of 1.5 m, between the plot boundaries and canopy.

Provided that more than one canopy may be permitted in the case of special buildings as per requirement.


(e) A projection of a maximum of 30 cm. on the rooftop terrace level may be allowed throughout the periphery of the building. In case of pitched roof projection of a maximum of 45 cm. at rooftop level throughout the periphery of the building shall be allowed.


(f) Accessory buildings :- The following accessory buildings may be permitted in the marginal open spaces :-


i)  In an existing building where a toilet is not provided, a single-storeyed toilet subject to a maximum area of 4.0 sq.m. in the rear or side open space and at a distance of 7.5 m. from the road line or the front boundary and 1.5 m. from other boundaries may be permissible. The Authority may reduce 1.5 m. margin in exceptional cases to avoid hardship.


ii ) Parking lock-up garage not exceeding 2.4 m. in height shall be permissible in the rear corner of an independent bungalow plot. Parking lock-up garage, when attached to a main building, shall be 7.5 m. away from the road line and shall be of such construction capable of giving fire resistance of 2 hours. The area of the sanitary block and parking lock-up garage shall be taken into account for the calculation of FSI.


iii)  Underground suction tanks, soak pits, and wet and dry garbage separately with collection chambers, space required for fire hydrants, electrical and water fittings, underground water tanks, dustbins, etc.
