GENERAL MEDICAL REFERENCE - SCIENCE DIRECT - AMERICAN PLANNING ASSOCIATION - (2017) VICTORIA AMMENDS OFF-STREET PARKING REGULATIONS : PUBLISHED DETAILS FOR VICTORIA : ZONING BYLAW 80-159, SCHEDULE "C" - OFF-STREET PARKING

“Apartment (dwelling unit secured as rental in perpetuity through a legal agreement) 0.50 spaces per dwelling unit that is less than 45m2 0.60 spaces per dwelling unit that is less than 45m2 0.75 spaces per dwelling unit that is less than 45m2 0.1 spaces per dwelling unit 0.60 spaces per dwelling unit that is 45m2 or more, but equal to or less than 70m2 0.70 spaces per dwelling unit that is 45m2 or more, but equal to or less than 70m2 0.90 spaces per dwelling unit that is 45m2 or more, but equal to or less than 70m2 1.00 space per dwelling unit that is more than 70m2 1.10 spaces per dwelling unit that is more than 70m2 1.30 spaces per dwelling unit that is more than 70m2”



"Some cities have tied new policies specifically to spur affordable housing. Seattle this past spring eliminated parking requirements for all nonprofit affordable housing developments in the city, among other provisions. A couple of years ago, Portland, Oregon, waived parking requirements for new developments containing affordable housing near transit. Also in 2016, New York eliminated parking requirements for subsidized and senior housing in large swathes of the city well served by the subway.

Even some suburbs are doing it. Santa Monica, California, removed parking requirements entirely last year for new downtown developments as part of a new Downtown Community Plan. And this year, the Washington, D.C., suburban county Prince George's, Maryland, revised its zoning code to significantly reduce parking minimums.

"We're trying to create a new model of mobility and not emphasize the car as much as we've done in the past," says David Martin, Santa Monica's director of planning and community development."

Parking costs a lot to build, and that cost usually ends up raising tenant rents.

$5,000: Cost per surface space

$25,000: Cost per above-ground garage space

$35,000: Cost per below-ground garage space

$142: The typical cost renters pay per month for parking

+17%: Additional cost of a unit's rent attributed to parking
