Home Addition FAQs
Frequently Asked Questions
How much does a home addition cost?
The cost of a home addition usually starts around $50,000 and can exceed $200,000+, depending on the size, scope, and finishes. A simple room extension will cost less than a full second-storey addition or an in-law suite with plumbing and electrical. We provide detailed quotes upfront so you know exactly where your budget is going.
Do I need a permit for a home addition in Caledon or Orangeville?
Yes. Most additions — including sunrooms, extensions, and second-storey builds — require permits to ensure they meet local building codes. We handle the permit process for you so everything is safe, legal, and approved.
What types of home additions add the most value?
The most valuable additions are typically kitchen expansions, extra bedrooms, in-law suites, and second-storey additions. These not only improve your lifestyle but also increase resale value significantly.
Can you build an in-law suite or rental unit as part of a home addition?
Yes, we often design and build in-law suites or separate living spaces that meet building code requirements. These are ideal for multigenerational families or homeowners looking to create rental income.
What’s the first step if I want a home addition?
The first step is a consultation where we review your needs, your budget, and the layout of your existing home. From there, we prepare a detailed plan and estimate so you can make an informed decision.
