(1) “ Special Buildings” means a) a residential or commercial buildings with more than 2 floors; or b) a residential building with more than six dwelling units; or c) a commercial building exceeding a floor area of 300 square metres:

Provided that any construction in the second floor with prior permission as an addition to an existing ground and first storeyed authorised ordinary residential building which is three years old shall not be construed as a “Special Building”

(2) (a) The minimum width of the public road on which the site abuts or gains access shall be 10 mtrs.

Provided that if the extent of the site is more than 1100 sq.m. a special building for residential use may be permitted on a site abutting or gaining access from 9m. wide public road.

Provided further that special building for residential use may be permitted with limitation on maximum number of dwellings and / maximum height of the building on a site abutting or gaining access from 9 m wide public road subject to compliance of the planning parameters stated in the Tables under sub rule (3) below.

The minimum width stated above shall be the existing width of the road and not the street alignment prescribed.

Explanation:

(i) Road width means the road space as defined in DR no. 2 (35). The qualifying road width for permitting special building shall be available atleast for a stretch of 250m along the length of the road abutting the site and the stretch from a junction can be straight or a curve or zigzag or combination of the above.

To cite examples:

a) If the road over its general length is of 10 metres width, but because of some kinks in front of the site one end is 9.8 metres and the other end is 10.2 metres is acceptable.

b) If the general road is of width less than 10 metres width, but only widens opposite to or nearer to the site is more than 10 metres, is not acceptable.

c) If the road is generally of 10 metres width upto a considerable length on one side, but discontinues and narrows into a road of smaller width on the other side of the site in question and the plot owner is willing to leave enough space for continuity of 10 metres road in front of his site, this will have to be checked and decided on case-by-case.

d) If the general road width is less than 10 metres and the site owner merely agrees to leave enough space to have 10 metres in front of his site only, this is not acceptable.

(ii) Road width measurements for the above purpose shall be of the road as designed and laid and the existence of unauthorized encroachments, for which no patta has been given, will not normally affect adversely provided the shortage in width in the min. stretch stated above does not exceed 10% of the min. prescribed width.

However permissibility or otherwise (in exceptional cases) in such specific situations will be decided case-by-case.

(b) If the site does not directly abut a public road but gains access through a private exclusive passage or through a part of the plot which can be treated as a passage from a public road of minimum width as prescribed above, the minimum width of such passage shall be as follows:

Sl.No. Description Minimum width

(1) When it is intended to serve six dwellings or up to 600 square metres of commercial building and the length of the passage does not exceed 80 metres.

3.6 metres

(2) When it is intended to serve upto 8 dwellings or upto 2,400 square metres of commercial building and the length of the passage does not exceed 100 metres.
