Subject to the provisions of this section, a highway authority may prescribe, in relation to either one side or both sides of a highway maintainable at the public expense for which they are the highway authority, a frontage line for building (in this section referred to as a "building line").
Where a building line prescribed under this section in relation to any highway is in force, no new building, other than a boundary wall or fence, shall be erected, and no permanent excavation below the level of the highway shall be made, nearer to the centre line of the highway than the building line, except with the consent of the authority who prescribed the line; and the authority may give a consent for such period and subject to such conditions as they deem expedient.
The prohibition imposed by subsection (2) above does not affect any right of light railway, tramway, electricity, gas water undertakers or sewerage undertakers to make an excavation for the purpose of laying, altering, maintaining or renewing any main, sewer, pipe, electric line, duct or other apparatus.
A condition imposed in connection with the giving of a consent under subsection (2) above is binding on the successor in title to every owner, and on every lessee and every occupier, of any land to which it relates.
If a person contravenes the provisions of this section, or any condition imposed in connection with the giving of a consent under it, he is, without prejudice to any other proceedings which may be available against him, guilty of an offence and liable to a fine not exceeding level 1 on the standard scale; and if the offence is continued after conviction, he is guilty of a further offence and liable to a fine not exceeding £2 for each day on which the offence is so continued.
Where in the opinion of a highway authority a building line prescribed by them under this section, or any part of such a line, is no longer necessary or desirable and should be revoked, they may revoke the line or that part of it.
Schedule 9 to this Act has effect in relation to the prescription of a building line under this section and to the revocation of such line or any part of it.
Any person whose property is injuriously affected by the prescribing of a building line under this section is entitled, subject to subsection (9) below, to recover from the authority who prescribed the line compensation for the injury sustained.
A person is not entitled to compensation under subsection (8) above—
Any two or more authorities on whom powers are conferred by this section may by agreement exercise those powers jointly, and the agreement may provide for the apportionment of any expenses incurred under it.
In relation to any prohibition or restriction on the use of land or buildings imposed by the Minister by the prescription of a building line under this section or by virtue of any condition imposed by him in connection with the giving of a consent under subsection (2) above, section 1(1)(c) of the Local Land Charges Act 1975 has effect as if the reference to the date of the commencement of that Act were omitted.
In this section—
"building" and "new building" have the same meaning respectively as in section 73 above; and
"light railway undertakers" means persons authorised by any enactment to carry on a light railway undertaking.
