A granny flat can be an effective way to lift rental income or house family, but it is not automatically the best use of your capital. The devil is in the detail. Before contacting builders or comparing quotes, the first question is strategy: is this about income, family, or value, and is there a better way to invest the same money?
From there it comes down to feasibility and the rules. Every council has its own position. Some allow granny flats as of right on the appropriate zoning, while others require development approval, and the answer changes what is possible and what it costs. Build quality and design matter too, because a poorly planned addition can cost more than it ever returns.
Treated as a considered part of a plan rather than an add-on, a granny flat can work well. Treated as a quick fix, it often disappoints.
