Exempt from Permission

Your rear extension is likely exempt from planning permission.

A single-storey rear extension of 28 sqm to a semi-detached house in Dublin falls within the exempted development thresholds under the March 2026 regulations. No planning application is required before starting works.

Key factors

  • Extension size (28 sqm) within the 40 sqm exempt threshold
  • Single-storey — roof height restriction is not a concern
  • Rear garden remains above the 25 sqm minimum required
Note: Confirm all previous extensions combined do not exceed 40 sqm before commencing works.

Based on: Planning & Development Regulations 2001, Schedule 2, Part 1, Class 1 (as updated March 2026)
