People also call it a modular garden suite, a panelized ARU or a prefab backyard home. In Toronto it is still an additional residential unit under By-law 574-2022, so it follows the same size, setback and fire access rules as any other garden suite. ### What does a prefab garden suite cost in Toronto? Installed prefab-hybrid suites run $140,000 to $240,000 with us. A 30 to 42 sqm panelized studio starts near $140,000. A 53 to 60 sqm modular two-bedroom reaches $240,000. Compared with a site-built detached suite of the same size, most owners save $20,000 to $40,000, mostly through shorter site labour and less weather risk. Be careful comparing prefab quotes: many cover only the factory box and leave out foundations, crane, servicing and permits, which can add $50,000 or more on a Toronto lot. ### What rules apply to prefab suites under By-law 574-2022? Exactly the same as site-built. Maximum 60 sqm (40 sqm on narrower lots), height and angular plane limits, rear and side setbacks, separation from the main house, soft landscaping and the 45 m fire access path all apply. The suite needs a Toronto Building Division permit and OBC Part 9 compliance. Factory modules are usually certified to CSA A277, so inspectors can accept the work done in the factory. A crane lift may also need a street occupancy permit from the City. ### Who installs prefab garden suites in Toronto? Prefab suppliers build the panels or modules, but someone has to own the lot work: feasibility, foundation, permits, crane, connections and finishing. We do that under one contract. Our founder, Dmitri Varga, P.Eng and BCIN Part 9, reviews supplier engineering and designs the foundation, and our in-house expeditor files the permit. ## What Our Prefab Service Includes ![Prefab garden suite wall panels stacked on a delivery truck next to a Toronto house ready for installation](/images/content/prefab-garden-suite-wall-panels-stacked-on-a-deliv.webp) ### 1\. Lot and access feasibility Our site evaluation [/garden-suite-feasibility/ →](/garden-suite-feasibility/) confirms eligibility and the envelope, then checks crane reach, street width, overhead wires, trees and the lift path. ### 2\. Design and supplier coordination We design to your envelope, then coordinate shop drawings with a panel or module supplier. The design stays yours, not a fixed catalogue plan. ### 3\. Permit with supplier engineering Our expeditor files the Toronto Building permit with supplier engineering and CSA documents. Details on our permit application [/garden-suite-permits/ →](/garden-suite-permits/) page. ### 4\. Foundation, set and connections Helical piles, a frost-protected shallow foundation or a slab, then a crane set or panel assembly. We connect Toronto Hydro, Toronto Water, sewer and heating. ### 5\. Site finishing Insulation details, drywall, kitchen, bath, flooring and millwork, finished to Toronto Green Standard Tier 1. ## How Does Prefab Compare With Site-Built? | Factor | Prefab-hybrid | Site-built detached | | --- | --- | --- | | Typical price | $140K - $240K | $180K - $340K | | On-site schedule | About 10 weeks | 10 - 16 weeks | | Permit path | Same, plus supplier engineering | Standard | | Weather risk | Low, framing built indoors | Higher, framing on site | | Design freedom | High, within panel or module limits | Highest | | Access needs | Crane or side-yard panel carry | Hand or small equipment | ![Side by side photos of a factory built panel and a site framed wall for a Toronto garden suite](/images/content/side-by-side-of-a-factory-built-insulated-wall-pan.webp) Prefab makes the most sense when you want a shorter disruption in the yard, when the layout is fairly simple, and when the lot has crane access. For complex shapes, big two-storey suites or very tight lots, a site-built detached garden suite [/detached-garden-suites/ →](/detached-garden-suites/) may be the better fit. ## How Do We Keep Prefab Suites Code-Compliant? Factory-built does not mean exempt. Every prefab suite we install goes through the same OBC Part 9 review, with third-party inspections at foundation, connections, insulation and final. Modules certified to CSA A277 come with a factory inspection label. Our standard spec meets Toronto Green Standard Tier 1, with a blower-door tested envelope, HRV and cold-climate heat pump. > **Watch the delivery path** > > The cheapest prefab suite can get expensive if the crane cannot reach. Overhead hydro lines, mature street trees and narrow streets in Old Toronto can push a lift to a larger crane or require panel carry. We check this before you sign, not on delivery day. ## Is Prefab Right for Your Budget? If your goal is the lowest all-in price for a rental or family suite, prefab-hybrid often wins. Our garden suite cost estimation [/garden-suite-cost/ →](/garden-suite-cost/) page compares build types side by side, and your feasibility report includes a prefab option when the lot suits it.

We rented the suite to our daughter and her partner, the mortgage math works.” Common Questions ## Prefab Garden Suites FAQs: Toronto Homeowner Questions Straight answers on cost, timelines, by-laws and permits for Toronto lots. ### Are prefab garden suites allowed in Toronto? Yes. A prefab or modular suite is treated the same as a site-built one. It must meet By-law 574-2022, Zoning By-law 569-2013 Chapter 150.7 and Ontario Building Code Part 9, and it needs a Toronto Building Division permit. Factory-built modules are typically certified to CSA A277, which lets inspectors accept work done in the factory, while the foundation, connections and site work are inspected on site as normal. Size caps, setbacks, separation from the main house and the 45 m fire access rule all still apply. The main extra step is planning delivery: crane access, street occupancy permits and the lift path over the house or along the side yard. ### How much does a prefab garden suite cost in Toronto? Installed prefab-hybrid suites run $140,000 to $240,000 with us, including permits, foundation, delivery, crane, connections and finishing. That is usually $20,000 to $40,000 less than a site-built suite of the same size. Watch out for prefab prices that only cover the box; the foundation, servicing and permit work can add $50,000 or more. ### How long does a prefab garden suite take? Factory fabrication overlaps the 12 to 14 week permit review. Once the permit is issued, on-site work runs about 10 weeks: foundation, crane set in a day, then connections and finishing. ### What is the difference between panelized and modular? Panelized suites arrive as flat wall, floor and roof panels and are assembled on the foundation in a few days. Modular suites arrive as finished boxes and are set by crane. Panelized handles tight access better; modular saves more site time. ### Can a crane reach my backyard? Usually, yes. We check street width, overhead hydro wires, trees and lift distance during feasibility. Where a crane cannot reach, panelized construction can be carried through a side yard. ### What foundation does a prefab suite need? The same as a site-built suite: a slab, a frost-protected shallow foundation or helical piles. Helical piles are popular for prefab because they are fast and limit digging near trees. ### Do prefab suites meet energy standards? Ours do. Factory panels are built tight, and we finish to Toronto Green Standard Tier 1 with an HRV and cold-climate heat pump. ### Can I pick my own finishes? Yes. Interior finishing happens on site, so kitchens, flooring, tile and millwork are chosen like any custom suite. ### Is a prefab suite lower quality? No. Factory framing is cut and assembled indoors, which avoids rain-soaked lumber and gives tighter tolerances. Quality depends on the supplier and the site work, which is why we manage both. ### Does prefab change the permit? No. The permit path is the same. We add the supplier's engineering and CSA certification to the submission. ### Still have a question about your lot? Send us the address and lot width.
