This is relatively inexpensive and can be sourced online.
Next, you will need a BASIX Certificate – this is a planning measure that applies to all granny flats over $50 000.
The Certificate states you are complying with environmental issues, i.e. the insulation and hot water system you must use will be mentioned in this certificate/report.
Based on other key factors of your design (the “sustainability commitments”), including the;
Type of windows,
Then BASIX estimates the;
Water and energy that you will use, and
Your thermal efficiency.
If you don’t meet the objectives of BASIX, you won’t be issued a Certificate, which must be submitted with your DA/CDC.
Owner Builder Permit
You will have to have passed an owner builder course. Either online or with an approved company in person. To find out the steps to take including what a “white card” is and how to get one. See this post about building a granny flat.
A sewer diagram is different from approval from your water supplier. A sewer diagram assists you in locating your:
Water companies’ pipes.
Private sewer pipes on your land, and
Point of connection to the companies’ wastewater system.
As mentioned, it is up to you to provide a copy of this to your builder, so they know where they can build on your land. By doing so, your builder can now also gain approval from your water company – i.e. a Section 50 Certificate or similar.
Accuse you of partaking in fraudulent behaviour, issuing large fines.
Instruct you to demolish the granny flat.
Do You Need Certificates for Warranty Claims or Insurance Claims?
A great builder will have a Home Owners Warranty as part of their contract, which will cover you when the:
Contracted building work is unfinished or faulty.
Builder died, disappeared, or become bankrupt during construction.
Builder doesn’t reply to a rectification order within 30 days.
The cover lasts:
6 years for structural flaws, and
2 years for non-structural flaws,
After construction is completed or the contract is terminated.
Check your contract for this, as, upon signing the contract, you should be provided a copy of your Home Owners Warranty certificate. If building yourself, Owner-Builder warranty is no longer available in NSW. As an owner-builder, you are guaranteeing the work you undertake.
However, it is a wise idea to invest in a form of insurance both whilst constructing and once building is complete.
