Note:- The existing Annexure-J in the finalised draft prerared by ISI is be substituted in
To-To by the following
ANNEXURE-J
The use, converage, FAR, set backs, open space, height, number of storeys, parking
standards etc. for various categories of buildings shall be as per the provisions contained in
Master/Zonal Plan and the amedments made in those from time to time. Wherever the
provision of Master Plan/Zonal Plan are silent on such issues or which require interpretation,
the norms as decided by the competent authority shall apply.
Some of the extracts relating to the above provisions from Master Plan as amended up
to 1st June, 1983 are reproduced as under :-
RESIDENTIAL USE ZONE :-
Irrespective of the actual number of servants quarters, for purpose of the density
calculations of considering layout plans, the number of servants quarters in various sizes of
plots will be reckoned as under :-
a)
b)
Plot upto 300 sq yards:
Plots above 300 sq. yards.
Nil.
Oneservant's quarter per dwelling unit (250 sq. mtr.)
Good planning practice for designs of residential areas should include:-
i) Light and air in the building;
ii) Protection against noise, dust and local hazards;
iii) Open space for various family needs;
iv) Easy circulation and access, safety from accidents;
v) As far as possible regular shape of plots; and
vi) A logical arrangement of residential plots by size and shapes.
The translation of these requirements into actual planning practice would vary with
design relation and density patterns.
INDIVIDUAL PLOTS:-
(Row houses, detached and semi -detached houses).
a) Minimum plot size'- The minimum size of an individual residential plot for a two storey, two
family dwelling, should be 125 square yards. In the case oflow cost housing for
92

low income-group and slum re-housing, the minimum plot size could be 80 sq. yds. for two
dwelling units, one on each floor, and about 33 sq. mt. (40sq. yds.) for single dwelling unittwo
storey building without a barsati floor.
NOTES:
1) "Each servant's quarter shall comprise one or more habitable room/rooms, kitchenette/ cooking
varandah/space, bath room and lavatory, subject to a minimum of a total floor space measuring
18.58 sq.mtr. (200sq. ft.).
2) "F or the purpose of density calculation, the number of persons per servant's quarter
will be reckoned as 2.
3) "The number of dwelling units on a plot will be reckoned as in the table below:-
Sl. No. Plot size No. of dwelling units
1. Not exceeding 500 sq. mt. One dwelling
unit on each floor.
2. Above 500 sq. mt. but not exceeding Two dweling units on each floor, whether
1500 sq. mt. attached or detached.
3. Above 1500 sq. mt. but not exceeding Three dwelling units on each floor whether
4. Above 2250 sq. mt. but not exceeding Four dwelling units on each floor, whether

ii)
Not exceeding 100 sq.yds.
Above 1 OOsq. yds. and not

Note:- (1) The area to be covered used in no case be less than the permissible covered area for the
large size plot in the lower category. For example, the area to be covered in a plot of 1028.44
sq.mt. (1230sq.yds.) will be 40% ofl003.3 sq.mt.(1,200sq.yds.) i.e. (401.34 sq.mts.) (480 sq.yds.)
and not 1/3 rd ofl028.44 sq.mt. (1.230sq.yds.) which is only 342.81 sq.mt. (410 sq.yds)."
c) Floors-In individual residential plots, normally only two storeyed buildings may be
allowed plus an optional provision of barsati floorat the top. In individual plots exceeding
167.23 sq.mt. (200sq.yds.) a building raised on stilits may be permitted provided the stilt
floor shall be treated as one of the main floors of the building.
Where a barsati is permitted, not more than 25% of the covered area on the ground floor
or the floor immediately below the barsati or 500sq.ft. whichever is less, should be allowed to be
covered including the area covered by a staircase leading to the barsati. The barsati may be
enclosed.
d) Frontage of plots-Each individual plot should provide minimum frontage of 18 ft. on the
access road, The ratio of depth to frontage should normally range between 3.0 to 2.0 is to
1.0.
e) Set back lines- The following set back, lines are prescribed depending upon the depth of
plot for individual plots.
f) Front set back.

the rear of the plots according to municipal bye-laws subject to height restriction to allow
sufficient light and air circulation.
iii) Side set back line-Sideset backs of at least 10ft. from plot line on each side should be
left on detached plots.
94

In semi-detached, plots side set back on one side should be at least 10ft. from the plot line to the
building line.
F or row housing, comer plots should be suitably, set back from the road right of way,
according to traffic requirements.
f) Service Lanes: The minimum width of the service lane shall be 15 ft. but it may be reduced to
10ft. in the case of law cost housing schemes sponsored by Government, SemiGovernment or
other public bodies. It is not necessary to have these in the case of detached and semi -detached
housing. If provided, it should have a minimum of 15 ft. right of way.
In the case of row and terraced housing, service lanes may be provided. It should have a
minimum right of way of 15 ft. In case the length of the lane is more than 500 ft. the minimum
right of way should be 20 ft.
Where garages are to be provided, in order to allow for easy turn of motor vehicle, the
garages should be set back 15 ft. from the centre line of the service lane.
GROUP HOUSING-
Group housing developments (two and multi storey apartmentsoflow cost housing
schemes)which will not be sub-divided into the customary streets and plots, will be governed by
good design standards to ensure open spaces and community facilities. The intensity of use and
the net density in these are intended to be higher than that stipulated in the plan, provided the
average gross residential density of the area under development of which the group housing is a
part, is in accordance with the density requirement of the plan. Also, no limits on the number of
floors is stipulated except those that may be imposed in areas neaar monuments, Airports etc.
Access to dwellings could be provided by walk way and pedestrian paths and their width would
also be governed by design requirements. Adequate provision has to be made for parking &
servicing & the walk ways should open on a residential street of at least 45 ft. or cul-de-sac or
loop street of at least 30 feet.
In case of group housing having more than two storeys, steps must be taken to ensure water in the
higher floors. For this purpose booster pumps and overhead tanks must be installed. Lifts and
suitable stair-cases should be provided for more than 4 storey high building. Also open balconies
for open air sleeping or air conditioning must be provided. In order to encourage higher storey
development which will provide more open spaces by having lesser coverage, a higher floor area
ratio is allowed. It is expected that development on group housing basis would be done according
to the Zonal Develoopment Plan. However, inrespect.ofplots size ofless than one acre group-
housing would also be permissible subject to the standards mentioned in foot note (3) on page 55
of the Master PLaan for Delhi as amended by the Table showing 'Plot size' and No. of dwelling
units given on page 89.

Floor area is defined as plinth area on all floors unless specifically excluded.
Notes:
1) The coverages will be calculated on the basis of the whole area reserved for Group
Housing after deducting:-
i) The area of collection stI:eets 80 feet wide and feeder streets 60 feet wide around
and within the group housing area. ('Residential streets, loop streets cul-de-sac,
service lanes will be deducted.)
j) The area for schools and other community facilities within the group housing
area; and
iii) The area for neighbourhood parks within the group housing area as shown in
the Zonal Development Plan (local open spaces, playground and tot-lots will not
be deducted).
2) The above basis will apply even in the case of group housing covering an entire
rieighbourhood, the whole of which will be treated as one scheme.
3) In density calculation for group housing, each servant's quarter will be reckoned as
one family.
4) The density of particular neighbourhood in which the group housing area is located will be as
shown in the Zonal Development Plan and the corresponding figure in the above table will be
operative unless otherwise prescribed in the Zonal Development Plan for a specific area.
5) The areas of barsati and mumti to the extent permissible for houses on individual
plots will not be reckoned in the FAR.

desirable environment. It also includes creation of several dwelling units out of one dwelling unit by
partition.
