I would love to see the occasional development that goes hard against parking. Build it over or across the street from Skytrain, provide 10% or more Modo/Evo spaces and zero or near zero residents parking. Then cut the price of everything by $60/120K given you're not having to build the cost of underground parking into the prices.
But even if you could persuade the appropriate council to do away with their parking minimums AND there was some way to discourage car owners from buying (have a neighbouring building with lots of parking? Sign some sort of contract?) I know people's lives change. Just because you work downtown and can take the Skytrain today, doesn't mean you're not going to be working in White Rock or Maple Ridge next year. Or a bunch of people are going to shrug, lie about car ownership, buy the cheaper unit and plan to park on the street somewhere - then complain about how they don't have parking in their building.
Actually, my GENIUS PLAN is for nobody to "own" any parking in a building. Have all the spaces owned by a parking organization that rents them out on a month-by-month basis. That way you reduce the price of every unit by the $60K that each space costs to build and the family buying a 2-bed who don't need parking don't pay for it and the couple buying a 1-bed who need two spots can get it too. Also there's none of the "I drive a monster truck but my unit came with a 'small car' space" or "I'm disabled but my unit's space is miles from the elevator" issues... you just rent out appropriate spaces to each unit depending on their needs.
But obviously the developer is going to want their money up front for the parking they built so whatever organization owns & manages the parking is going to need DEEP pockets and the return on investment is very very slow.
