Where a local authority gives notice under Section 81 they must also give a copy to the owners and occupiers of any building adjacent to the demolition site and the statutory undertakers.
Lle bo awdurdod lleol yn rhoi hysbysiad o dan adran 81, mae'n rhaid iddo hefyd roi copi i berchnogion a deiliaid unrhyw adeilad ger y safle dymchwel, sef yr ymgymerwyr statudol.
