Boundary encroachment and neighbour's rights

Extensions and alterations must not infringe upon neighbouring properties through encroachment of foundations, guttering, or overhanging structures. Permission may be required to access neighbouring land for maintenance purposes.

Although not a planning matter, an extension or alteration to a dwelling should not infringe upon a neighbouring property. It is an infringement of a neighbour's civil property rights should foundations or guttering encroach onto their land or if an extension overhangs or attaches to their property. Where an extension abuts or runs close to a property boundary, permission to enter neighbouring land may also be required to enable approved works to be carried out for future maintenance purposes. This may require formal agreements and homeowners are advised to seek their own legal advice in relation to any of these issues.
