Parking, for rental mixed-use buildings can around 1/4 of the overall construction costs. So for a 12,000sf site, on a major transit route and arterial road in Vancouver, even with relaxations (3/4 of residents get a stall), and 7 commercial stalls you're looking at squeezing in 2 levels of underground parking at about $2.5 million. Most areas to build taller rental buildings in Vancouver (4-6 storeys) are along routes that promote mixed-use, so commercial parking requirements are always an issue.
Now, looking at many areas within
this policy that we use to be able to actually rezone sites to build rental and apartments, we're still required to build at least above 50% parking stalls for all the units for the majority of the sites. So at 4 or 3 1/2 storeys you're still looking at 1 level of underground parking or more (due to site constraints) and the same $1.5-$2.5 million for an underground parkade. Not to mention land can be almost as much as your hard costs.
How do you get away without building parkades, units with more than 1 bedroom, and allowing your price per square foot to be lower and thus being able to change less for rents? Easy. You build a fraction of the number of units not along major transit routes or arterials, more in single-family homes neighbourhoods at about 3.5 storeys tall with the anticipation that you can get at least 2 car share stalls (= 10 car stalls). With that you can maybe build 15 units, and that's if the community and City staff allows that relaxation. Units prices will hold to what the City dictates I the rezoning policy.
Meanwhile vacancy is under 1%, apartments rent for high rates, land prices are high, and car use is dropping and commutes by car are under 55%. Almost a whole underground level is now occupied by bike storage, unit storage, mechanical rooms, stairwells and elevators, parking ramps and drive aisles... on a site that's 12,000sf and 1 level of parking, you could fit 17-19 parking stalls at maybe 44 units (including 2 and 3 bed units). That's about 50% stall to unit ratio with a $1.5 million parkade almost 1/4 of your construction cost.
