Since the law mandates at least one parking spot per unit in brand-new condo buildings, why don't we just start incorporating the price of the one designated parking spot into the price of the living space, and mention "extra" spaces available in the body of the listing?
One of the biggest pet peeves of agents and buyers alike is the way the MLS listing sheets are not set up to designate the parking price (over and above the unit price) in the main part of the listing. In most cases you have to hunt through the "fine print" of the listing sheet (or even worse, the display or classified advertisement), to discover that–"oops, yes you can afford this place if all you buy is the condo, but with parking it will go over your mortage approval limit!"
With all the money we Realtors have to shell out to CAR/MLS, the least they could do is hire someone to redesign the template to accommodate the parking price!

I've seen that treatment at a few different projects, including Canyon Ranch Living above. That $50,000 price is more of a value than an actual ticket price (according to the sales rep I spoke with), seeing as how parking is factored into each home's cost.

Local Relator,
The law doesn't mandate 1 parking spot per unit.
The zoning code dictates the minimum number of parking spots. I believe it is .6 per unit.

The zoning code requirements for parking vary, based on the zoning classification and a number of other factors.

I thought it was .8, but it's no longer 1 to 1 per dwelling unit (house, rental, condominium etc). And nothing says that it (the parking space) has to be sold with the unit as far as I am aware, just provided.

Sheridan B,

Now that Larry and Sergey have given us this thing called Google, it's easy to find the relevant chapter of the Chicago Zoning Ordinance (pdf file).

I'm surprised that people aren't embarrassed about speculating when facts are readily available.

As I noted earlier, the requirements vary.
