Blue Mountains City Council
What owner-builders need to know before lodging with Blue Mountains City Council — the state-wide approval pattern that applies here, plus anything we've specifically verified about this council.
The general pattern — applies statewide
- 01You need council/certifier approval before building — either a Development Application (DA), assessed on merit, or a Complying Development Certificate (CDC), a faster path (can be approved within 28 days) if your project meets pre-set state standards exactly.
- 02A Construction Certificate must be issued before building work starts, confirming your plans comply with your DA/CDC conditions.
- 03A Principal Certifier must be appointed before construction begins — council itself or an accredited private certifier.
- 04Your council's DCP can add requirements on top of state-wide standards (stormwater/on-site detention rules, setbacks, tree preservation, heritage overlays) — this is exactly where "I followed the national standard" isn't automatically enough.
Specific to Blue Mountains City Council
Environmentally Sensitive
A specific sequencing gotcha worth knowing: your Owner-Builder Permit copy must be submitted to your Private Certifying Authority before your Construction Certificate is released, not just before work starts. Council also flags HBCF insurance directly on its own approvals guidance. Expect extra scrutiny generally — this LGA carries real bushfire and heritage overlay exposure on top of the state-wide rules.
