PLANNING ASSESSMENT

Covers householder extensions, countryside dwellings, agricultural permitted development, change of use, listed buildings, enforcement, renewables, signage, and more.

Policy sources: Planning Act (NI) 2011 · GPDO (NI) 2015 · PPS 21 · SPPS Edition 2 (December 2025) · Planning (EIA) Regulations (NI) 2017
