The new listing form has six steps: Location, Space details, Photos, Price, Availability and Review & publish. To open it, select New Listing in the host menu, or New listing on your Overview page. If Next is greyed out, the reason is shown beside it.
Only addresses in Kitchener, Waterloo and Cambridge are accepted. The address is shown on your listing, so keep gate codes and other private details for the instructions box in the next step.

Select Add photos and add at least one. The first photo is your cover, the one guests see in search. Use Set as cover to change it. Show the empty space, a parked car for scale, and the street entrance.
Parking needs a Per hour rate, storage a Per month rate and event spaces a Per day rate. Use Add another spot if you have more than one. See Set your prices and availability.
Choose whether the listing has an end date and block any dates you already know you can't offer.
Check the summary, use Edit to fix anything, then select Publish listing. You need to have finished ID verification first. If it's still being checked, you'll see ID check still pending.
Your listing goes live as soon as you publish. You'll see Listing published! with a link to share, and the listing shows as Live on your Listings page.
