What is a Citizen Developer and who can become one?
Citizen Developers are owner-occupants who build new housing on single-family properties.
With the right tools and guidance, this kind of development has the potential to be more equitable than for-profit development and is readily feasible.
Multi-Generational Households
Older generations provide the bulk of a down payment, whereas younger generations provide the income for a mortgage.
Firstime Home Buyers
News outlets are reporting that many well-employed individuals, who believe they should be able to buy a home, are unable to. Co-ownership may be an option.
Downsizers
They need to downsize but don’t want to leave their neighbourhood and community. Instead, they pool together their resources to create smaller units within their single-family home.
Resident Developers
They own their house and are looking to generate extra income by creating new housing units on their property.
Non Profit Housing Providers
They develop and/or mangage affordable housing within Toronto’s neighbourhoods. Scattered site housing is a new model which can preserve and enhance the supply of affordable housing within existing low-rise neighbourhoods.
