Some Important Considerations About Installing a Granny Flat on Your Property

A granny flat is a type of outdoor space or guest house built onto a home's backyard or side yard. It became popular many years ago as an alternative to having an elderly in-law move into the family home with children and grandchildren; it still keeps them close while affording everyone some privacy. Today a granny flat has many uses, but you want to consider some important factors about having it built on your property before you decide this is the right choice for you.

1. Ensure you have the right permits for its intended use.

When you build a granny flat on your property, of course you need the right building permits and inspections, since the space will have its own wiring and plumbing. You may also need a final inspection before you can move anyone into the space.

However, remember that if you plan on renting the space to someone, this may make it a commercial property and not a private space. You may need a zoning variation for your home, if you're not allowed to run any type of business on your property due to zoning laws. In some cases, this may not be necessary, but before you assume that you can have a granny flat built and then rent it out as a second income, note the legal restrictions or requirements for this in your area.

2. Consider ease of access when planning.

Be sure you've considered how someone will access the granny flat when planning its design. You may like the look of a granny flat facing your home so that it seems more welcoming and inviting, but this may mean having to create a new pathway from your driveway to the granny flat for access. For someone in a wheelchair, you may need to put down concrete and not use decorative river rocks, and this may be unsightly. Be sure you've considered access to the flat when making your plan or design.

3. Note the maximum size allowed.

Typically a granny flat can be no more than 60 square meters in size. When you're designing a granny flat with a builder, he or she may mention this maximum size, but don't assume you can just add on to the granny flat at a later date. The 60 square meters doesn't typically cover outside features such as a porch, but don't assume you can tack on an extra bedroom once the flat is built. This might result in fines from your local city or state council. Be aware of this limitation when you make your plans for the flat and its use.
