Blue Mountains City Council Demolition Guide 2026

Demolishing in the Blue Mountains LGA 2026 — CDC vs DA, fees, common conditions and timing.

Blue Mountains City Council covers Katoomba, Leura, Springwood, Glenbrook, Blaxland, Wentworth Falls, and the upper mountains. Almost entirely bushfire-prone.

Approval Pathway: CDC vs DA in Blue Mountains

Most straightforward single-dwelling demolitions in Blue Mountains qualify for a Complying Development Certificate (CDC) issued by a private certifier under the State Environmental Planning Policy. CDC is faster (1–3 weeks once your paperwork is complete) and typically cheaper than a DA.

A Development Application (DA) through Blue Mountains City Council is required when the property has heritage overlays, bushfire-prone or flood-affected zones, dual-occupancy splits, or non-standard demolition proposals. DAs typically take 6–14 weeks.

Typical Fees in Blue Mountains (2026)

CDC certifier fee: $1,200–$2,500 — issued by a private certifier (not Council)
DA lodgement (residential demo): $1,500–$4,500 to Blue Mountains depending on cost-of-works band
Long Service Levy: 0.25% of cost-of-works on jobs above the threshold

Frequently Asked Questions

How long does demolition take in Blue Mountains?

Single-storey: 3–5 days on site once services are disconnected. Two-storey: 5–8 days. Add 1–3 days if asbestos or a pool is involved.

Does Blue Mountains City Council require a DA for every demolition?

No. Most single-dwelling demolitions on standard residential blocks qualify for a CDC. Heritage, bushfire, flood or non-standard proposals push the job to a DA.

The property owner pays Council and certifier fees direct. The demolisher's quote covers the actual demolition, asbestos removal, disposal and site clean-up.
