If you own a house or a lot in Toronto or the surrounding GTA, it may be worth far more as a multi-unit rental property. We handle the whole journey — feasibility, design, permits and construction — so you end up with more units, more equity and monthly cashflow.
Duplexes, triplexes and fourplexes designed to maximize rental units and cashflow on your lot.
Convert or replace an existing home with a multi-unit building that pays you every month.
Low-rise rental apartment buildings, from feasibility and design through permits and construction.
Add a rental unit to your property with a garden suite or laneway house.
Unlock the value of your land — rezoning, severances and the highest-and-best-use plan.
Cashflow modelling, financing and joint-venture structures for investors and landowners.
A single lot can often support a duplex, triplex or fourplex — turning one mortgage into several rent cheques.
New construction adds value the day it’s finished, and rental income helps carry and pay down the project.
Toronto’s multiplex rules now allow up to four units on most residential lots — we confirm what yours can do.
We model rents, costs and financing up front so you see the cashflow before committing.
We develop multiplexes and small apartment buildings across the city and the surrounding GTA.
We assess your lot, zoning and the highest-and-best-use, then model units, costs and rental cashflow.
Architecture and drawings tailored to your site, through municipal approvals and building permits.
We build it — managing trades, budget and schedule to a quality finish, on time.
Your new units are ready to lease, generating income and long-term equity.
On most residential lots in Toronto you can now build up to four units as-of-right under the city’s multiplex (EHON) rules — no rezoning required, subject to standard zoning and building requirements. We run a free feasibility study so you know exactly what your lot can support before you commit.
Often, yes. Many Toronto and GTA homes can be converted — or replaced — with a duplex, triplex, fourplex or small apartment building to generate rental income. We assess your property, zoning and structure, then model the numbers first.
It depends on the lot, unit count, design and finishes. As a rough guide, new multiplex construction typically runs about $325–$425 per square foot, while converting within an existing home can be less. We give you a free feasibility estimate covering hard and soft costs, timeline and projected rental cashflow — with real numbers for your address.
Typically: design 2–4 months, permits about 1–2 months, and construction roughly 8–12 months for a conversion or 12–24 months for a full new build. We give you a schedule up front and manage it end to end.
Toronto has been waiving development charges on multiplex conversions of up to four units — often tens of thousands of dollars in savings per project — and has relaxed parking requirements. Programs and rules change, so we confirm the current incentives that apply to your specific project.
Minimum parking requirements have been removed for multiplexes across much of Toronto, which makes many more lots financially viable. We confirm what applies to your address as part of the feasibility review.
It comes down to your lot size, zoning, budget and the rents your neighbourhood commands. We model each option — units, cost and cashflow — so you can choose the one with the best return, not just the most units.
It varies by property, unit mix and financing, but the point of a multiplex is to turn one mortgage into several rents. We build a property-specific cashflow model — rents, costs, financing and projected return — so you see the numbers before you build.
Often yes — where the lot allows, a garden suite or laneway house can add another rental unit on top of your multiplex, increasing income with a smaller additional build.
Toronto and the surrounding Greater Toronto Area — including Etobicoke, North York, Scarborough, East York, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville and more.
Yes. We model the rental income, financing options and returns up front so you can see the cashflow and the numbers before any shovel hits the ground.
