> American housing and zoning laws are overly focused on compliance with issues like wheel chairs that significantly drive up costs. Most accessibility affordances have a negligible cost when designed in from the beginning and are significantly more expensive to retrofit. (E.g. designing a staircase with an integrated ramp is cheap; adding a ramp to an existing staircase often is not.) Ensuring that everyone has equal access to society seems like a pretty worthwhile goal and I'd hate to see people locked out of it to save a fraction of a percent in costs.
