FAQ Granny Flats

These are the 3 most questions that I get asked when it comes to granny flats and I thought I would share it with everyone.

Before I delve into them, what is a granny flat ? The name originated as a means for families to accommodate ageing parents, since then the introduction of the 2009, NSW Government Affordable Housing State Environment Planning Policy (SEPP) made it permissible for residential home owners who fulfill the requirements to build in their backyard under a streamline, efficient process. These granny flats where then being used to not only accommodate growing families, it was also an excellent opportunity for investors and the like!

1. Is my property eligible for a Granny Flat ?
The short answer is Most Likely ! Most properties are eligible for granny flats, that’s why they are so popular. So long as your property meets the following criteria your good to go:
• Minimum 450 square metre area & 12m Frontage
• Maximum of 1 Granny Flat is permissible per lot
• Must have a 24m² courtyard space for the Granny Flat, with an area of at least 4m wide
• Conditions may apply if building in a bushfire, flood affected or heritage area

2. How much?
In the grand scheme of things the return on your investment is undeniable. Not only are you maximising the value of your land you are also securing a very liquid return on your investment through the rental yield.

With respect to pricing, it really depends on size and quality of finish. Think of granny flats as a blank canvass, you can ultimately choose every single aspect of the construction from floor layout, to finishes, to even the colour of the rainwater tank. Anything is possible as long as we are within the requirements.

One thing important to note is that detached granny flats are more affordable compared to to adding on to your existing home, due to things such as fire rated walls, roofline etc.In this country you get for what you pay for, so if something sounds too good to be true, in most cases it is. Cheap construction methods, terms and conditions, and inclusions are vital areas of concern.

3. What’s the process involved?

Step 1.

Design & Approvals – Without relevant approvals you cant do anything. The first element of the Design & Approvals is the Initial Survey & Concept Plan. This is where a registered surveyor will come to your land and conduct an external survey which then gets sent to an architect for a Building Zone Map (essentially a blueprint of your land with the Natural Ground Levels, Setbacks etc)

From here its up to you to organise a floor plan your happy with and ultimately get that stamped by a Private Certifier which can take as little as 10 days!

Step 2.

Construction – This is the fun part !

1. Concrete Slab
2. Frames Erected
3. External Coverings, Roof, Windows
4. Fitout (Bathroom & Kitchen)
5. Practical Completion

Hope that was insightful 🙂
