If you own a home in Toronto in 2026, you’ve likely noticed the shift in our housing landscape. With property values continuing to climb and the demand for rental housing at an all-time high, homeowners are looking for ways to maximize their space. One of the most effective ways to do this is by adding a separate side entrance.
Whether you are looking to create a legal basement apartment, build a second dwelling unit for family, or simply improve accessibility, a side entrance is a strategic investment. However, you can’t just cut a hole in your foundation and call it a day. In Toronto, a side entrance requires a building permit, specific structural drawings, and a deep understanding of the local zoning bylaws.
At KeyDraft Designs, we help homeowners navigate the complexities of the City of Toronto’s building department. In this guide, we’ll break down everything you need to know about getting your side entrance permit fast and why professional oversight is non-negotiable.

1. Why a Side Entrance is a Game-Changer in 2026
Adding a side entrance isn't just about aesthetics; it’s about functionality and ROI. In the current market, the flexibility of your home dictates its value.
- Rental Income: A side entrance is the first step toward creating a compliant second dwelling unit. This allows you to offset your mortgage with a reliable monthly tenant.
- Multi-Generational Living: Many Toronto families are opting to keep parents or adult children close while maintaining privacy. A separate entrance provides that "home within a home" feel.
- Accessibility: If you have family members with mobility challenges, a side entrance often provides a more direct, grade-level path into the home compared to steep front stairs.
2. The Legal Reality: Why Building Permits are Mandatory
We often get asked, "Can’t I just hire a contractor to put the door in over the weekend?" The short answer is no. A side entrance permit is a legal requirement in Toronto for several critical reasons:
- Structural Integrity: When you cut into a foundation wall or an exterior load-bearing wall, you are altering the skeleton of your house. Without a permit and proper structural drawings, you risk the house settling or, in extreme cases, collapsing.
- Fire Safety and Egress: The Ontario Building Code (OBC) has strict rules about "means of egress." If you are using the entrance for a basement suite, it must meet specific height and width requirements to ensure people can escape during an emergency.
- Insurance and Resale: If you ever try to sell your home or file an insurance claim, and the city finds an unpermitted entrance, you could face massive fines, be forced to fill it back in, or have your claim denied.
3. Understanding the 2024 Zoning Reforms (And How They Help You Now)
There is good news for Toronto homeowners. In October 2024, the City of Toronto implemented significant zoning updates that have made the process much smoother in 2026.
Before these changes, placing an entrance on the front of a house was often restricted, forcing homeowners into expensive Committee of Adjustment hearings. Today, the rules are much more flexible:
- Multiple Locations: You can now place entrances on the front, side, or rear walls of detached and semi-detached houses.
- No Limit on Number: The city no longer strictly limits the number of entrances you can have, provided they meet safety standards.
- Fewer Variances: Because the bylaws are now more inclusive, the need for Committee of Adjustment assistance for simple side doors has drastically decreased, saving you months of waiting.
4. The Critical Role of Structural Drawings
This is where many DIY projects fail. A permit application isn't just a form; it’s a package of technical documents. For a side entrance, your application must include detailed structural drawings.
These drawings demonstrate to the city's plan examiners that your project is safe. They typically include:
- The Lintel Detail: A lintel is the beam placed across the top of the new opening to support the weight of the wall above. We calculate the exact size and material (steel or reinforced concrete) needed.
- Foundation Reinforcement: If you are digging down to create a "walk-out" entrance, we need to show how the surrounding foundation will be supported and how water will be drained away from the house.
- Site Plan: This shows where the door sits in relation to your property lines to ensure you aren't infringing on "setbacks."
At KeyDraft Designs, we specialize in creating permit-ready house plans that address these technical requirements from day one.
5. Connecting Your Side Entrance to a Legal Basement Apartment
Most side entrance inquiries are the result of a larger goal: a legal basement. In Toronto, for a basement to be "legal," it must be recognized as a second dwelling unit.
The side entrance is the "gateway" to this legality. To be compliant, the entrance usually needs to lead to a dedicated fire-rated corridor or be the direct exit for the unit. If your goal is rental income, we highly recommend looking at our architectural design permit services to ensure the entrance is placed in a way that maximizes your interior floor plan.
6. The Step-by-Step Toronto Permit Application Process
As of 2026, the process is entirely digital, but it still requires precision. Here is how we handle it for you:
- Initial Consultation & Measuring: We visit your property to take precise measurements and assess the existing structure.
- Drafting the Plans: Our team creates the architectural and structural drawings, including the site plan and construction details.
- Digital Submission: We submit the package through the Toronto Building online portal.
- Plan Review: A city examiner reviews the plans to ensure they meet the Ontario Building Code and Toronto Zoning Bylaws.
- Permit Issuance: Once approved, you receive your permit, and construction can officially begin.
Pro Tip: Incomplete submissions are the #1 cause of delays. If one detail is missing, the city will "bounce" your application, putting you back at the end of the line.
7. Typical Costs and Timelines for 2026
While every project is unique, here is what you can generally expect when applying for a side entrance permit in Toronto today:
- City Permit Fees: The base fee for residential permits is approximately $4,380, plus additional costs per square meter of work. If you are adding plumbing or HVAC for a second suite, expect additional trade permit fees.
- Design and Engineering Fees: This covers the professional drawings required for the application.
- Timelines: Standard residential reviews typically take 8 to 13 weeks. However, with KeyDraft Designs ensuring a "right the first time" submission, we aim to minimize the back-and-forth that usually drags these timelines out.
