Planning Your Home Addition

Measurements and Area Drawings

While adding an addition to your property can take up to a year, setting up a clear plan will ease the process. Consider these steps:

Step 1: Obtain a Building Permit

According to the City of Toronto, homeowners need a building permit for home additions that alter the structural foundation of a house.

The most convenient time to submit your building permit application is in January. It takes about 2-4 weeks to get your permit application approved, and starting the application process in January will guarantee you can begin your home addition project by the time it is spring. This way, you will avoid weather-related hiccups during the home additions process.

Step 2: Know Your Budget

The first and most important step in a home additions project is determining your budget. As soon as you figure out how much you want to spend on a home addition, the later stages will be smooth sailing.

Step 3: Get Quotes

As soon as you have a clear budget for your home addition, you should seek out a home remodeling contractor. Here are some key factors to look for in a good contractor:

  • Full transparency with customers
  • No hidden fees or fine-print conditions
  • Punctual, flexible, and organised
  • Good reputation and industry experience

Types of Home Additions

Although there are many ways in which you can add onto your house, the most common types of home additions include:

railings and staircases with glass panels

1. Second Storey Additions

A storey addition (also known as building up, top-up addition, 2nd floor addition etc.) is when you add onto your house vertically. Adding a floor to a house is typically done in two ways:

  • Tearing the roof off the main floor, installing a new one, and building a second storey from scratch.
  • Removing the roof off the main floor temporarily, adding a new level, then putting the old roof back in place.

What determines the type of floor addition is how the existing roof is constructed. Sometimes a roof is not made to hold the weight of an entirely new floor. In this case, it is best to completely remove it and construct a new one that acts both as a ceiling to the main floor and a base to the second floor.

Other times, a roof can be strong enough for a storey addition, in which case there is no need to remove it and install a new one. Temporarily removing it and putting it back in place will suffice.


2. Bump-Out Additions

A bump-out addition (also known as building out, side addition etc) is when you add onto your house horizontally. What this means is that the contractor must install a new foundation or slab in order to build the addition.

The wonderful thing about most bump-out additions is that you do not have to move out of your house during the addition project. This type of addition is the least disruption to the existing space.

One thing to consider about bump-out additions is having yard space necessary to build the new extension on. You will also have to make sure your home addition aligns with city construction requirements in terms of space between your property and your neighbour’s.

3. Garage Additions

A garage addition can be beneficial both for your convenience and the value of your property. With garage additions, there are the following options:

  • Adding a detached garage on your property
  • Adding an attached garage to your house

Adding a garage not only makes space for your car, but it also comes with extra storage space.

Garage addition is a great investment if you choose to utilise it as a living space, such as a living room or bedroom. In the event you do not plan to use the added garage yourself, you can rent it out. You can also invest in a garage top-up addition later on to increase your living space.

At Luxor Development, we offer all types of home additions. If you wish to add an extension to your house, our experts are more than glad to off you home addition advice.

Benefits of a Home Addition

The reason that drives homeowners to seek a home addition is the benefits that come with it. If you add onto your house, you can expect the following advantages:

  • Adding Space to Your House

The most obvious benefit that comes from adding an extension to your house is increasing your property’s square footage. What is more, this added space will be customised exactly to your liking as long as it does not violate any city laws.

  • Increase House Value

A home addition will add tremendous value to your house. This is a great advantage in case you want to sell your house in the future. Also, not only does a house addition improve your house’s resale value but it makes it more appealing to potential buyers, as well. A smart extension to your property will guarantee your house sells.

  • No Moving Expenses

Although adding a room to your home is a big financial undertaking, it is still much cheaper than moving to a new house. This is because a home addition project eliminates the fees of packing, hiring movers, and shipping. So no matter how much a home addition costs, it remains a much cheaper option than moving into a new house.

The work we do at Luxor Development ensures you make the most out of your home addition. We guarantee high-quality results so you can reap in all the advantages of adding a room to your house.

Home Additions FAQ’s

Does home addition require a permit?

Yes, all home additions require a permit. No matter the size or shape of your plan it requires its drawings approved by the city building department. You can find the appropriate city address and email address on your city’s website. For Toronto, this is on page 29 of the Toronto Building Permit Guide.

Should I sell my bungalow or add a second story addition?

You can add a second story addition to raise resale value, but the area you live in will determine if this is a good investment or not. In some cases, it may be better to sell your bungalow. Consult with an experienced renovation company to determine the best option for you.

How long does it take to do a home addition?

A typical home addition can take anywhere between 5 months and 10 months, including permit acquisition and negotiations with your contractors. This also depends on the size and complexity of the addition, the season you are working in, and second-story additions will usually take more time than ground-floor ones.

Do I need move out during a home addition?

What kind of trades do I need for a home addition?

How long does it take to get a home addition permit?

It can take between 1 month and 3 months to get your home addition permit, but this differs from city to city. In Toronto, it can take between 5 and 20 days.

Are there any limits for house extensions?

There are requirements for height, roof alterations, and the height of the first floor above the established grade among other things.
