Our Guide to Land Surveys for Home Re-modelling

When undertaking a home re-modelling project, one of the earlier steps involved in the process is to enlist the help of a professional land surveyor to assess your property and ultimately—if everything goes well—give you to the go signal to commence work. This, however, is not always the case, as a formal land survey is not at all needed for some projects.

In this article, we’ll go deeper into detail to clear up the matter for you. If you are unsure as to whether or not you need a land survey for your upcoming house re-modelling, continue reading to learn everything you need to know to make an informed decision.

What is a land survey, anyway?

A land survey, in the broadest of terms, is a highly scientific process of evaluating a parcel of land to determine the structural and legal viability of a construction project. It takes into account many factors found in a given geography, such as its physical dimensions, soil quality, and surrounding structures.

In the case of home re-modelling, a land survey is most often used to reestablish property lines between different parcels of land. (Because a more extensive land survey would have already been conducted before the home’s construction.)

These boundaries are identified and marked for the basic purpose that you do not encroach on them. In other words, a land survey is needed to ensure that any properties adjacent to yours are not affected by your home re-modelling project.

So, do I need a land survey?

It depends.

If your home re-modelling project is restricted to the confines of already-existing structures, then you won’t need a land survey.

However, if your project involves demolishing a structure or extending the footprint of your home, you might be required to hire a land surveyor to formally inspect your property. The construction of a new fence along the perimeter of your property is another situation that might call for their services.

Basically, the closer your project is to your property lines, the higher the chance you will need the services of a professional land surveyor.

Other important considerations

It’s also advisable for you to have your property surveyed if you are not the original owner of the home or if it’s a particularly old structure. This is because you need to know about any changes in property lines, building restrictions, and easements that may have taken place since the house was first built.

In any case, having your property formally surveyed before beginning a remodel project is generally a good idea. Doing so will let you be certain that your neighbours remain unaffected by your project, and you’ll also be able to avoid potentially expensive and time-consuming problems in the future.


To summarize, a land survey is not always required but is always helpful. If you are limiting the project to the interiors of your home, then you probably won’t need one. If, on the other hand, the work extends past existing structures, then it’s usually best to conduct one just to be sure.
