What is the 149 (2&5) Certificate and Sewer Service Diagram?

Section 149 Planning Certificates are issued in accordance with the Environmental Planning & Assessment Act 1979. They contain information on how a property may be used and the restrictions on development.

Most councils’ Planning Certificates are issued under Section 149 (2) and 149 (5) of the Environmental Planning and Assessment Act 1979. A separate request can be made for a Section 149 (2) Certificate which confirms whether complying development may be carried out under the State Environmental Planning Policy 2008 (Exempt and Complying Development).

Information to be disclosed on a Section 149 (2) Planning Certificate is specified under the Environmental Planning and Assessment Regulation 2000 (Schedule 4) and includes the following where relevant:

  • Names of relevant planning controls (i.e. SEPP’s, LEP’s, REP’s, DCP’s)

  • Zoning and land uses under the planning control
  • Critical habitat

The Section 149 (2) Planning Certificate contains the above information. The Section 149(5) Planning Certificate provides information on the last approved use.

Our Granny Flat Approval Process in greater detail

  1. To start your granny flat approval process first get in contact with us, we will make time for you to visit our display.
  2. Then our staff at Master Granny Flats will take you through our display granny flat and give you a real experience of what one of our granny flats looks and feels like, presenting our premium quality and a taste of the services we provide. During your time with us we will also book you in for an on-site inspection & quotation of your property.
  3. After this one of our experienced builders will come out to your property and evaluate your site incorporating your ideas of how you would like the granny flat to be laid out and transforming it into construction reality. Determining the direction of our approval process either through a private certifier (CDC) or Council (DA),  We will provide you with a fix price quotation incorporating all on-site costs.
  4. Our design team will organise a detailed survey plan that drafts your existing property which will enable us to design a granny flat that works with your existing property.
  5. We will invite you in to give us your ideas, working together to achieve the perfect design for your property. Our main goal is to achieve the right floor plan in the right position.
  6. Our design team will complete all necessary documentation which includes elevations, structural drawings, BASIX certificates, etc. while liaising with you through our approval process.
  7. Our construction team will take care of the whole process from site setup to hand over. You as a client will have peace of mind with a site foreman controlling quality and making sure that our program runs on time.
