There is a difference between mixed use zoning and not having ridiculous building height restrictions and still having both public and private works insure there is adequate sewer and electric capacity for the growing city. If anything, you should shift the barrier a bit. Instead of saying you cannot build because X Y or Z, change it to be that you cannot rent or sell or open to the public without X Y and Z. It kills the nimbyism if the building is already there, but still keeps consumer protection in place to stop you from ending up in an apartment building built this century with exposed asbestos.
