What it means for Markham Real Estate
Housing policies across Ontario have been evolving as governments look for ways to increase housing supply and improve affordability. Once a proposal is being discussed in many cities is allowing up to four residential units on a single property “as-of-right,” meaning homeowners could build additional units without special approvals.
However, the mayor of Markham, Frank Scarpitti, has recently expressed opposition to allowing four units as-of-right on residential lots in the city. This decision highlights ongoing debates around housing density, infrastructure capacity, and neighbourhood planning.


What Is “AS-of-Right” Four-Unit Housing?
“As-of-right” housing policies allow property owners to add additional residential units without requiring rezoning or special approval from the city.
In most cases, this could include”
- A main residential unit
- A basement or secondary suite
- A garden suite or laneway home
- An additional apartment unit within the property
Supporters believe this approach can help increase housing supply in established neighbourhoods.
Why Markham Is Taking a More Cautious Approach
City officials have expressed concerns about allowing four units on every residential lot.
Some of the main concerns include:
Infrastructure and Services
Higher housing density could increase demand:
- roads and transportation
- water and sewer infrastructure
- schools and community facilities
Municipal leaders want to ensure infrastructure can support population growth before allowing significant increases in housing density.
Neighbourhood Planning
Some residents are also concerned that allowing four units on single-family lots could significantly change neighbourhood character.
Possible impacts include:
- increased traffic
- parking challenges
- higher population density in low-rise communities
Cities often try to balance housing growth with maintaining neighbourhood planning goals.
What This Means for Buyers and Investors
For real estate buyers and investors in Markham, this decision suggests that adding multiple rental units to a single property will likely continue to require municipal approvals rather than being automatically permitted.
Investors interested in multiunit potential properties should carefully review current zoning regulations and city bylaws before purchasing or planning renovations.
However, secondary suites and legal basement apartments remain common ways for homeowners to add rental income while complying with municipal regulations.
The Bigger Housing Conversation
Across the Greater Toronto Area, municipalities are continuing to debate how to address housing shortages while maintaining sustainable urban planning.
Some cities are adopting policies to increase density more quickly, while others are moving more gradually, depending on local infrastructure and community feedback.
For buyers, sellers, and investors, staying informed about housing policies and zoning changes can help identify future opportunities in the market.
