5 Most Unexpected Building Costs with a Laneway House

So how much does a laneway house cost to build? This section will break down how much you can expect to spend on each hidden cost and why these are important to invest in when building your laneway house.


1. Surveyor

The first overlooked cost to build a laneway house is for a survey of your property. This should be done before you get started on the project. Hiring a surveyor can cost as little as $2,000, depending on several factors. One reason why this is so important is that it helps you see the property lines to make sure that you are building on your property and that you’re not too close to your neighbour’s property. The survey is the best way to get all of the necessary information on your property so that you are on the right side of the law before you get started on constructing your laneway house. The surveyor will stake out the foundation to ensure that your property is legal.

2. Landscaping

The second most overlooked laneway house construction cost is landscaping. While most of the focus is put on the design of the laneway house, it is important to remember that your yard will take a lot of physical abuse throughout the construction process. Most builders do not include landscaping services in their quotes, leaving homeowners scrambling for a solution when they could be focusing on moving in or renting their new laneway suite. For landscaping you can expect to spend about $5,000 or more for the project. It’s best not to start landscaping until after the laneway house is built, but having a plan in place will save you time and money in the long run. This procedure can ensure that the property looks appealing to renters, adds to the curb appeal of your property and makes the space look beautiful. This wise investment will yield the most return for your money.

3. Engineering

While architects are great, you will most definitely need an engineer for the project. Their job is to take the drawings that the architect creates and certify them. An engineer can add $7,500 or more to your laneway house construction cost, but this isn’t an area in which you should skimp. The engineer knows the laws and what’s required to make sure the house is safe and legal. They include material details in the drawings so the builder knows what needs to be done to construct the safest laneway house possible. This includes knowing what materials are needed for what purpose. They offer essential knowledge that is important to avoid any problems in the future that could come up if the laneway house isn’t properly built.

4. Architectural Drawings
