6.1 No building shall be constructed on any site, on any part of which there is deposited refuse, excreta or other offensive matter objectionable to the Authority, until such refuse has been removed therefrom and the site has been prepared or left in a manner suitable for building purposes to the satisfaction to the Authority.
6.2 Damp Sites
Wherever the dampness of a site or the nature of the soil renders such precautions necessary, the ground surface of the site between the walls of any building erected thereon shall be rendered damp-proof to the satisfaction of the Authority.
6.3 Surface Water Drains
Any land passage or other area within the curtilage of a building shall be effectively drained by surface water drains or other means.
6.3.1 The written approval of the Authority shall be obtained for connecting any subsoil or surface water drain to a sewer.
6.4 Distance from Electric Lines
An overhead line shall not cross an existing building as far as possible and no building shall be constructed under an existing overhead line. No accessible point from any Verandah, balcony, or the like shall be allowed to be erected or re-erected or any additions or alterations made to a building not having the following minimum clearances from an overhead electric supply line, in accordance with the current Central Electricity Authority (Measures Relating to Safety and Electric Supply) Regulations, 2010 as amended from time to time:
a) Clearance of buildings from lines of voltages and service lines not exceeding
-
An overhead line shall not cross over an existing building as far as possible and no building shall be constructed under an existing overhead line.
-
Where an overhead line of voltage not exceeding 650 V passes above or adjacent to or terminates on any building, the following minimum clearances from any accessible point, on the basis of maximum sag, shall be observed:
i) For any flat roof, open balcony, Verandah roof and lean-to-roof:
a) where the line passes above the building, a vertical clearance of 2.5 m from the highest point, and
b) when the line passes adjacent to the building, a horizontal clearance of 1.2 m from the nearest point, and
ii) For pitched roof:
a) where the line passes above the building, a vertical clearance of immediately under the line, and
b) when the line passes adjacent to the building, a horizontal clearance of .
-
The horizontal clearance shall be measured when the line is at a maximum deflection from the vertical due to wind pressure.
-
Any conductor so situated as to have a clearance less than that specified above shall be adequately insulated and shall be attached at suitable intervals to a bare earthed bearer wire having a breaking strength of not less than 350 kg.
b) Clearances from buildings of lines of voltages exceeding 650 V
- An overhead line shall not cross over an existing building as far as possible and
no building shall be constructed under an existing overhead line.
- Where an overhead line of voltage exceeding 650 V passes above or adjacent to any building or part of a building, it shall have on the basis of maximum sag a vertical clearance above the highest part of the building immediately under such line, of not less than:
i) For lines of : 3.7 m upto and voltages including 33 kV; exceeding and 650 V
ii) For lines of : 3.7 m plus 0.30 m voltages for every additional 33 kV or part thereof. exceeding 33 kV
The horizontal clearance between the nearest conductor and any part of such building shall, on the basis of maximum deflection due to wind pressure, be not less than:
i) For lines of : 1.2 m voltages exceeding 650 V and up to and including 11 kV
ii) For lines of : 2.0 m voltages exceeding 11 kV and up to and including 33 kV
iii) For lines of : 2.0 m plus voltages exceeding 0.3 m for every additional 33 kV or part thereof
- For high voltage direct current (HVDC) systems, vertical clearance and horizontal clearance, on the basis of maximum deflection due to wind pressure, from building shall be maintained as below:
| Sl No. | d.c.Voltage | Vertical Clearance | Horizontal Clearance |
|---|---|---|---|
| kV | m | m | |
| (1) | (2) | (3) | (4) |
| i) | 100 | 4.6 | 2.9 |
| ii) | 200 | 5.8 | 4.1 |
| iii) | 300 | 7.0 | 5.3 |
| iv) | 400 | 7.0 | 6.2 |
| v) | 500 | 9.1 | 7.4 |
| vi) | 600 | 10.3 | 8.6 |
| vii) | 800 | 12.4 | 10.7 |
PART 3 DEVELOPMENT CONTROL RULES AND GENERAL BUILDING REQUIREMENTS
6.5 Distance from Water Course/Area
Distance of site from the normal edge of water course/area may be specified by the Authority, keeping in view the normal maximum flood/tide level.
6.6 Size of Plots
6.6.1 Residential
Each plot shall have a minimum size/frontage corresponding to the type of development as given below:
| SlNo.(1) | Type of Development(2) | Plot Size (3) | Frontagem(4) |

6.6.1.1 The minimum size of the site for group housing development shall be as given in the Master Plan and local development control rules.
6.6.2 Industrial
The size of the plot shall not be less than and its width shall not be less than .
6.6.3 Other Land Uses
The minimum size of plots for buildings for other uses not covered under 5.5 shall be as decided by the Authority. Various requirements with respect to cinema buildings shall be in accordance with the good practice [3(2)].
