Regulation 7 Principles of the scheme in respect of the erection of small domestic buildings, certain garages, carports and extensions
Where building work comprises–
erection of one or more small domestic buildings; or
erection of a detached building which consists of a garage or carport (or both) with a total floor area not exceeding 40m2 and which is intended for use with an existing dwelling; or
extension of any dwelling by a floor area not exceeding 60m2, including extension by the erection or extension of an attached garage or carport which is intended for use with the dwelling,
a local authority are authorised to determine their charges for that building work by reference to the floor area of the building or extension, as the case may be, and in the case of the work mentioned in sub-paragraph (c) the charges so determined shall cover any associated work relating to means of access.
Where building work is of a kind mentioned in paragraph (1) above, a local authority may determine that an inspection charge shall not be payable where the total floor area of the building or extension is less than 10m2.
Where any building work of a kind mentioned in paragraph (1)(c) comprises or includes the erection of more than one extension to a building used or intended to be used for the purposes of a single dwelling, a scheme shall provide that the total floor areas of all such extensions be aggregated in determining the relevant charge payable.
Where the aggregation of the floor area of all extensions referred to in paragraph (1)(c) does not exceed 60m2, the scheme shall provide for the relevant charge to be based on the total floor area of the extensions.
Where the total or the aggregation of the floor area of one or more extensions referred to in paragraph (1)(c) exceeds 60m2, the scheme shall provide for the relevant charge to be based on the estimated cost of the building work as prescribed in Regulation 6.
