3420 St Clair Ave East Townhouses: A 21-Unit 1977 Complex in Clairlea

3420 St Clair Ave East Townhouses is about as small as a condominium townhouse complex gets in Scarborough: 21 homes, built in 1977, on the north side of St Clair near Birchmount. Small can be wonderful when the owners are organised, and expensive when they are not. My job here is to show you how to tell which one you are buying into. I’m Jatin Dua, RE/MAX Quantum Realty.

Twenty-one owners, one budget

Every shared cost in this complex is divided by 21. If the corporation needs a $300,000 roof and window program, that is roughly $14,000 per home before the reserve fund contributes anything. The reserve fund is what stands between owners and that bill.

That is why I read a small corporation’s documents differently from a tower’s. I want to see a recent reserve fund study, a funding plan the board is actually following, audited statements without surprises, and minutes that show problems being dealt with rather than deferred.

The upside of 21 owners is real too. Decisions can be made quickly, there are no amenities to fund, and owners tend to notice when something needs attention. A well-run small complex is often a pleasant, quiet place to live.

Insurance deserves a question of its own. A small corporation buys its building insurance without economies of scale, so ask what the premium and deductible are, and which damage below the deductible the owner pays for under the bylaws.

The complex across the road

3420 has a sibling. 3409 St Clair Avenue East, directly opposite, was registered as YCC-302 on the same day, 5 January 1977. The consecutive numbers suggest the same builder developed both, although I could not find a record naming it.

Today they are entirely separate. 3409 has 31 units and is managed by Sterling Condominium Services; 3420 has 21 and is managed by RealWorld Property Management. Their fees, reserve funds and repair histories have had five decades to drift apart.

If you like the location, look at both. Request both status certificates, compare the reserve fund balance per unit, and ask each seller when the roofs and windows were last done. The cheaper house is not always the better buy.

Different managers can also mean different habits: how often the reserve fund study is updated, how quickly repairs are made, how clearly owners are told about them. The minutes of each corporation are the best window into that.

Living in a 1977 townhouse

This complex dates from the first decade of condominium ownership in Ontario, which began with provincial legislation in 1967. The YCC prefix comes from the old York registry used at the time.

Condos.ca records a single storey, no suite sizes and no amenities. I would treat all three as gaps in the record rather than facts about the homes. Walk the unit, count the levels, measure the rooms and ask how parking works, because no parking is recorded either.

Inside, the systems that matter at this age are the electrical panel and wiring, the furnace and air conditioner, the water heater and any original plumbing. Find out from the declaration which of these are yours to maintain and which belong to the corporation, and ask the seller for receipts for anything replaced.

Outside, ask about roofs, windows, doors, siding or brick, fences and paving. Each should have a date in the reserve fund study. If several are listed as original, they are coming due together.

If a previous owner renovated, ask for permits and for any written approval from the board for work that touched the exterior, such as windows, doors or a deck. In a small complex, approvals are sometimes informal, and you inherit whatever was agreed.

The St Clair and Birchmount area

Clairlea-Birchmount is a settled residential part of southwest Scarborough, with Birchmount Road and St Clair Avenue East as the main local streets. The panel on this page covers schools, parks, shops and transit in detail, so I will focus on what is changing.

Kennedy Station is the main transit hub for southwest Scarborough. It is the southern end of the new Scarborough Busway on the old RT route, scheduled to open on 30 September 2026, and the starting point of the Scarborough Subway Extension to Sheppard and McCowan, expected around 2030.

Neither project changes this street directly, but both make southwest Scarborough better connected over the next few years, which supports long-term demand for family housing near Kennedy.

If you drive, try the rush-hour route to your work before you commit. If you rely on transit, use the routes in the panel and make the trip at the time of day you would actually travel.

How I would price a home here

There were no listings here when I checked, and condos.ca publishes no suite sizes, price per square foot or fee figures for the complex. I am not going to guess.

What I can tell you is how to approach it. Start from what the complex can and cannot offer: house-style space and no amenities, in exchange for a small owner base that carries every repair.

With only 21 homes, sales are rare, so the best comparables are 3409 St Clair across the road and other 1970s townhouse complexes in Clairlea-Birchmount. Adjust for size, renovation, parking and each corporation’s financial position.

In a complex this small, the reserve fund per unit is part of the price. A home in a well-funded corporation is worth more than an identical one facing a large unfunded repair. For the recorded sales at this address, I can pull them through my building sold report.
