Do they ban them entirely?

Disneyland is tough as Anaheim has banned STRs.

The old SF Airbnb ordinance was an effective ban on short-term rental units in a multi-family or apartment building, although you're right that many people (including my friends) ignored the ban and rented units without any oversight.

Sadly I have to ban new users almost every day for bad posting, spam, and utter meanness.

Although the court declined to lift the ban immediately, the ruling means the current moratorium will expire at the end of July.

Even though cities started moving away from lead in the 1920s, it wasn't officially banned until 1986!

Use caution as STR are being cracked down on and banned in many areas, Arlington, Texas is one unless in the entertainment district which is roughly a mile circumference around ATT Stadium.

Also on top of that investors are banned from buying and are forced to wait few weeks while property is being offered to live in buyers.

I just got a notice from the local REI club that HUD is working on banning all seller financing.

The downside to HOAs is that they can potentially ban rentals.
