@Andrew C. No they are not. Many realtors I know have 20 or more doors in that configuration as they are cash cows.
Short not all inclusive summary of regulations:
You need a Zoning Permit for limited lodging to rent your home for up to 30 consecutive days to any one person or group.(This is about taxes)
You need a Zoning Permit for Visitor Accommodation:
- To rent your home for stays of 30 days or fewer.
- If the property is not your primary residence.
Housing requirements
- Smoke alarms must be installed:
- In each bedroom.
- In the hallway in the immediate vicinity of the bedrooms.
- On each floor of the home, including basements.
- Carbon monoxide alarms must be installed:
- Within 15 ft. of the entrance to every bedroom or within 15 ft. of a bed in sleeping areas if there isn’t an enclosed bedroom.
- Centrally on a wall or the ceiling, but not directly in front of a door to a bathroom or within 5 ft. of a cooking appliance.
- Under the installation requirements for smoke alarms if they are combination smoke and carbon monoxide alarms.
- You can’t post signs for lodging on your home.
- The home can’t be occupied by more than three people (including the owner and renters) who aren’t related by blood, marriage, life partnership, adoption, or foster-child status.
- You cannot change your house so that it no longer resembles a private residence.
Information you must provide your renters
- Renters are only allowed to have guests between the hours of 8 a.m. and midnight.
- You must tell renters the trash and recycling collection days and any trash disposal rules and regulations. You must provide proper trash containers for renters.
- Excessive noise is prohibited and violators are subject to fines and penalties.
- The owner or their designee must provide contact information to the renters. The contact person must handle any complaints from the renters.
It is not that onerous and the licensing procedures are available on line.
I always recommend that you speak with a accomplished realtor in the area who deals in short term rental properties. DM me if you want a recommendation.
