Liverpool Council Granny Flat Size and Setback Rules
Under the Liverpool LEP 2008 and the Housing SEPP, the following rules apply to granny flats in Liverpool LGA:
• Maximum floor area: 60sqm (internal habitable area) • Minimum lot size: 450sqm • Maximum height: 8.5m (pitched roof) or 3.8m (flat roof) • Side setback: 900mm minimum • Rear setback: 3m minimum — Liverpool Council's DCP strongly prefers 3m+ rear setbacks • Front setback: Must be behind the building line of the principal dwelling • Maximum 2 bedrooms • Must be fully self-contained (own kitchen, bathroom, bedroom, living) • One granny flat per lot only • Cannot be Torrens-title subdivided • Car parking: 1 space required for the granny flat • Private open space: Minimum 24sqm • Landscaped area: Minimum 30% of site area (Liverpool DCP)
Liverpool Council also requires stormwater detention on all new builds — including granny flats. Buildana includes stormwater design in every Liverpool project.
CDC vs DA Approval — Liverpool Council
Most granny flats in Liverpool LGA qualify for CDC (Complying Development Certificate) approval:
**CDC pathway — recommended:** • Timeframe: 10–20 business days • Cost: $3,000–$5,000 • No council lodgement required — assessed by private certifier • No neighbour notification • Available when the site meets all prescriptive standards
**DA pathway — when CDC isn't available:** • Timeframe: 40–80 days (Liverpool Council's average) • Cost: $5,000–$10,000 (council fees + consultant reports) • Required for: flood-prone land (parts of Moorebank, Chipping Norton), heritage items, bushfire-prone areas, or sites that don't meet CDC setbacks
Liverpool has several flood-affected suburbs along the Georges River corridor. If your property is on flood-prone land, DA is mandatory and Liverpool Council will require a flood study. Buildana checks flood mapping during every free site assessment.
