A development permit may not be required where the use is permitted, no overlay applies and every relevant planning requirement is met.
Hazard, heritage and other overlays may require a development permit.
A registered building certifier must be engaged for the building approval process.
Power, water, sewerage or on-site wastewater requirements must be satisfied.
A demountable unit may be used, but it must still comply with all relevant planning and building requirements.
