frequently asked home addition construction Questions

Please reach us at info@completeworksconstruction.com if you cannot find an answer to your question.

The most affordable ways to add an additon to your home include coverting or renovating an existing basement or garage or coverting an existing room into two. These options allow you to use space that you already have more efficiently.


To add an addition onto your home or onto your property in Ontario you will need a permit and drawings. We assist in this process and work with engineers and architects. We usually meet with you first to discuss a layout and create a budget for your project. This involves creating a scope of work, an estimate, and a design consultation.


Adding an addition onto your home can cost between $200 to $600 a square foot depending on size, location, how many bathrooms, and rooms you are looking to have. We sit down with clients to determine their need for space and create a plan within their budget.  


In Ontario, you need permission and need to apply for a building permit to add on to your home. This usually involves an application to the city that you live in and must include drawings that have been signed by an engineer or architect. We work with these local professionals and help our clients through the permit proccess.


A secondary dwelling is another name for a rental unit. There are currently funding programs and initiatives offered by the government for these types of renovations. Feel free to ask us for more information.


There are currently government programs available for low interest loans and some grants to build what the govenment refers to as secondary suites and accessory dwellings. Eligible constructions can borrow up to $80,000 at very low interest. Please contact our office for more information!


It all depends on your local zoning rules, how much space you have, and what type of dwelling you are trying to construct. You will need engineered drawings, an approved permit, and a scope of work and estimate from a contractor.


A sunroom when enclosed is often considered a home addition in Durham Region. It can be an open addition onto your home without doors or it can be a private enclosure with doors and act as a separate space in your home yet be accessible from the inside. 


Yes, you can add an addition onto your home to use as a rental unit. Your Home Addition can include a separate entrance for this purpose. Ask our Home Addition contractors about the new funding initiative offered by the government for building ADU's, which includes home additions.
