BUILDING (PLANNING) REGULATIONS - REGULATION 22

Permitted site coverage and plot ratio may be exceeded in certain cases

(Past version on 30/06/1997).

Adaptation amendments retroactively made - see 29 of 1998 s. 27

(1) Where, between ground level and a height of not less than 5.5 m or, where
the Building Authority is satisfied that there will be no obstruction to
vehicular traffic using the street, 3.3 m above ground level, a building on a
class A, B or C site is set back from a boundary of the lot on which it is
erected, being a boundary that abuts on a street, and, with the consent of the
Government, the part of the lot that is thereby not built upon is dedicated to
the public for the purposes of passage- (L.N. 406 of 1987; L.N. 57 of 1988)

   (a)  the site coverage for the building or for any one part of the building
        may exceed the permitted percentage site coverage, so, however, that
        the site coverage therefor does not exceed that percentage of the area
        of the site equal to the sum of the permitted percentage site 
        coverage for the building or for that part of the building, as the
        case may be, and the figure obtained by dividing the product of 1 500
        and the area of the lot so dedicated to the public by the product of
        the area of the site and the height of the building; and

   (b)  the plot ratio for the building or, if the building is a composite
        building, for the domestic part of the building may exceed the
        permitted plot ratio, so, however, that the plot ratio therefor is not
        greater than the permitted plot ratio for the building or for that
        part of the building, as the case may be, by more than 20 per centum
        or does not exceed the sum of the permitted plot ratio for the
        building or for that part of the building, as the case may be, and the
        figure obtained by dividing the product of 5 and the area of the lot
        so dedicated to the public by the area of the site on which the
        building is erected, whichever is the less. (L.N. 294 of 1976)

(2) Where part of a lot, being a part that abuts on a street, is acquired by
the Government, either by agreement or by resumption under the
Lands Resumption Ordinance ( Cap 124), for the purpose of street widening, the
Building Authority may permit-

   (a)  the site coverage for a building erected on that lot, being a class A,
        B or C site, or for any one part of the building to exceed the
        permitted percentage site coverage, so, however, that the
        site coverage therefor does not exceed that percentage of the area of
        the site equal to the sum of the permitted percentage site coverage
        for the building or for that part of the building, as the case may be,
        and the figure obtained by dividing the product of 1500 and the area
        of the part of the lot so acquired by the Government by the product of
        the area of the site and the height of the building; and (L.N. 294 of
        1976)

   (b)  the permitted plot ratio for the building or, if the building is a
        composite building, for the domestic part of the building to exceed
        the permitted plot ratio, so, however, that the plot ratio therefor is
        not greater than the permitted plot ratio for the building or for that
        part of the building, as the case may be, by more than 20 per centum
        or does not exceed the sum of the permitted plot ratio for the
        building or for that part of the building, as the case may be, and the
        figure obtained by dividing the product of 5 and the area of the part
        of the lot so acquired by the Government by the area of the site on
        which the building is erected, whichever is the less. (29 of 1998 s.
        27)

(3) For the avoidance of doubt, it is hereby declared that-

   (a)  where under paragraph (1) or (2) the permitted percentage site 
        coverage is exceeded in relation to a part of a building, the site 
        coverage for any other part of the building shall not exceed the
        permitted  percentage site coverage;

   (b)  nothing in this regulation shall be taken or construed as derogating
        from the provisions of regulation 25 as to the amount of open space to
        be provided about a domestic building.

(4) In this regulation, the expression "permitted percentage site coverage"
(准許上蓋面積百分率) means the maximum site coverage permitted under
paragraph (1) or (2), as the case may be, of regulation 20. (G.N.A. 97 of
1962)
