Gosford council & CDC compliance

Gosford falls under Central Coast Council jurisdiction. Key approvals pathways:

• CDC (Complying Development): Granny flats under 60m² on blocks over 450m² typically qualify. Faster than DA (20 business days vs 40–60 days). We coordinate private certifier, bushfire reports (if required), and engineering.
• DA (Development Application): Required for new builds, large extensions, or granny flats that don't meet CDC criteria (e.g. heritage overlays, bushfire flame-zone land). We prepare all documentation and coordinate with Central Coast Council.

Bushfire-prone land (BAL ratings)

Many Gosford properties (especially hillside and bushland-interface blocks in Kariong, Springfield, Narara) are classified as bushfire-prone. We engineer all granny flats and new builds to meet BAL (Bushfire Attack Level) requirements — typically BAL-12.5 to BAL-29 for Gosford. This includes:

• Ember-resistant construction details
• Non-combustible cladding and roofing
• Bushfire shutters or screens (if required for BAL-40+)
• Bushfire Attack Level report coordination
