Why you cannot build just anywhere on your property

Building lines, setbacks, flood lines, land covenants, caveats, and more

So you think you can position your new home just anywhere on your property. Or maybe you're planning to extend your home, perhaps adding extra bedrooms, a garage, bathroom, even a patio, what's to stop you? After all the whole property belongs to you - surely you can build anywhere?

Before you make an expensive mistake and have to demolish all or part of your newly constructed home read this.

​Spoiler alert - no you usually cannot build your home anywhere on your property.

Building lines (setbacks) – not constructing on your boundary

Some properties, estates, towns and cities have restrictions on how close to the property boundary and the road that you can build. Often this is related to the property zoning. Setbacks could be two metres (six feet) or more on the sides. In a suburb near us the front setback from the property boundary at the road is nine metres (30 feet). This can radically impact your proposed building plans. Some regulations have larger setback requirements for the second storey of the house, which means that it has to be situated further from the boundary. Always check where the front setback or building line is measured – is it from the front boundary, or the edge of the road, and if it’s the road is it from the front or back of the road kerb.

In some cases with your neighbours consent you may be able to get some relaxation of the building lines along the sides, but don’t count on it.

It’s important to note that the building lines or setbacks often apply to the edge of the building. So for instance, if the roof overhangs the house forming eaves, and the roof edge has a gutter, then the outside edge of the gutter will normally be the point from which the minimum distance to the boundary is measured. Of course always make enquiries as to where the measurements are taken and ensure these answers are in writing. You can usually construct swimming pools, retaining walls and driveways within the setback (that is closer to the boundary). You can plant gardens and sometimes place gazebos and movable sheds closer to the boundary.

In Florida this builder had to demolish a nearly completed home because it was constructed to close to the neighbour's home. Read more about this expensive mistake.

​Land covenants (caveats) – when your property isn’t all yours

​The land may have covenants (which may be shown on the property plans, registrations, or in sale agreements) which could include:
  • Providing right of way for neighbours to access their properties. You cannot build on this portion which could obstruct access to the neighbouring property, unless you can negotiate alternate access for your neighbour.
  • Servitudes, which is land under which utility providers and the local authorities have their gas, sewer, drainage and water pipes, or electrical and telecommunication cables. Sometimes these areas are set aside for future use – which means that one day they could move their excavators onto your property to start installing a pipe. It’s not possible to build structures in areas designated as servitudes. In addition, these providers (and their contractors) will have the authority to access your property whenever a problem occurs with their pipe or cable, or to undertake maintenance work.
  • Road widening reserves. Some properties may have a road widening reserve. This means that a portion of the property along the boundary with the road could be expropriated (purchased) from you to be incorporated into a new wider road. You will have no right not to sell the land at the designated price (which is normally determined to be the fair market value at that time). If a portion of your property is determined to be a road reserve you aren’t allowed to build any structures within the reserved area. But, more importantly, should the road be widened you may find that the road and its traffic is suddenly right on your doorstep.
These servitudes, reserves and right of ways should be shown on the property plans, but if none are shown its good practice to visit the local planning offices to make enquiries. Always check where the measurements are taken from.

​Flood lines (flood limits) – where you could be flooded

Properties close to rivers, or in low-lying areas may be prone to flooding. Flood lines aren’t something that are visible on the property, they are hypothetical levels where water from the nearest stream or river could reach during a flood event. The lines are usually shown on plans of the property, or on overall maps of the area. These lines are often measured as the likelihood of the water level reaching this point. So a one-in-twenty year flood line indicates that the water could reach this level every twenty years. Of course, just because the water reached this level last year doesn’t mean that it can’t, or won’t, reach the same level next year or that it won’t happen in the next twenty years. In fact, with changing weather patterns in many areas the probability of more frequent and bigger storm events is increasing. So many authorities will restrict building activities below say one-in-twenty year flood lines, even below one-in-fifty year flood lines. But also, many insurance companies will not pay for damage caused to buildings and their contents if they are constructed in an area that could be flooded, or the insurance premiums may be excessively high.

Case study: We considered purchasing a house that had a large front garden which sloped down to a small stream flowing through the park in front of the house. The house was set back right near the street. There seemed to be ample space on the property to extend the house if needed. However, on further investigation we discovered that the house could not be extended towards the river. In fact no structures could be built on this part of the property because it was within the flood line of the river.

It’s not just that you can’t build within the flood line, but you may also be unable to landscape the area, or materially change the ground levels in anyway.

I’ve seen areas flooded that you would never have thought would be flooded, since they were some distance from rivers. People then tried to claim from their insurance policy only to find that the policy small print excluded flood damage.
​
When considering any property that’s close to a river (even within a couple of kilometres (miles)) it pays to make enquiries and understand the extent of previous floods in the area and their impact.

Conclusion

When purchasing a new property check where you can build your new home. You may find that you cannot build just anywhere on the block of land.

Before building a new home or extending your existing home, understand the limitations of your property - what part of your property can you build on.

Excellently written article!!! You have covered every detail effectively. Building is not what we do daily. It's a one time investment so we should consider all the points that you mentioned before making a huge investment. Thanks for sharing precise knowledge with us.

I just saw your article about building setbacks. I have to admit that it helped me understand the concept a lot better. You are so right in saying that it's not always clear what they mean by "setback." I'm glad you wrote this article because now I know for sure when my contractor needs to ask about setback distances.
Great idea for an article! Thanks again :)

I was reading your latest blog post and I wanted to say thank you for writing this. It's been a long time coming! I noticed that in the article you shared some valuable insights on how to find the perfect property for your needs. I thought of an additional way though, by using a software specifically designed with home-builders in mind. It ensures that when building new homes or extensions of existing properties, there are no limitations - any part of your land can be built on safely and securely.
