Some thoughts on the Rental 100 plan: I’ve browsed
the City’s Rental 100 documents and I don’t expect great things.
I can’t speak to the impact of waiving development cost levies (not something I’m especially familiar with), but the density bonuses are pretty minimal. The worst part is that RS (1-family) and RT (2-family) zones are ineligible for the density bonus, so it doesn’t apply to most of Vancouver.
An even bigger issue is that I doubt cities' ability to incentivize meaningful amounts of rental construction (vs condos). The deck is really stacked in favour of homeownership by provincial and federal policies (primary residence exemption, RRSP Home Buyers' plan, non-taxation of imputed rent, BC Homeowner Grant); cities would need to take drastic measures to counteract the cumulative impact of those policies.
tl;dr: I’d be surprised if the program incentivized construction of a meaningful number of units, but I'd be happy to be proven wrong.
