Building Certificate (Section 149A)

A Building Certificate is a certificate issued by Council that states it will not make certain Orders or take certain action under the Environmental Planning & Assessment Act 1979 or the Local Government Act 1993.

This includes Orders (or take proceedings for an Order) to have the building covered by the certificate demolished, altered, added to or rebuilt. The certificate also means Council will not take proceedings in relation to any encroachment by the building onto land under the control of Council, for a period of 7 years.

A certificate is usually applied for when selling houses or other property.

My section 149 planning certificate says my land is Biodiversity Certified, what does that mean?

If your land is biodiversity certified then development may proceed without the usual requirement under the Environmental Planning and Assessment Act 1979 for site-by-site specific threatened species assessment.

Certified Lands

‘Certified’ lands are those where development proposals require no further threatened species assessment.

Biodiversity Certification is not an automatic approval to clear native vegetation; it simply means that on certified lands, threatened species assessments are no longer required during Development Applications (DAs) or when undertaking local and regional infrastructure works.

Precinct Planning will seek to retain and enhance existing vegetation and habitat to provide important amenity and open space benefits to future residents.

Although threatened species assessments are no longer needed, relevant approvals to clear native vegetation - such as that commonly required by Councils or under Commonwealth legislation – may still be necessary.

‘Non-Certified’ Lands

There is no change to the approval processes in areas which have not been certified (‘noncertified’ lands). Threatened species assessments may still be required before development applications can be assessed within non-certified lands.

Development within non-certified lands will be subject to existing planning and assessment

requirements, including an assessment of the impact of development on biodiversity.

Advice for Landowners

Landowners may still need to conduct a threatened species assessment for development proposals that include the removal of native vegetation. Proposed clearing of native vegetation is still be subject to the Growth Centres SEPP or other Council requirements.
