Hello, I have a two-unit SFH (first floor unit & second floor unit which share a main entrance but have separate private entrances once inside the house), located in California (I know...).

Esprit Wood stair case will be much cheaper than the metal ones - ideally going to a door that is up at the top of them and not a window so that it's a second entrance/exit to the unit.

Painted window frames and doorway/entrance.

We have seen Brampton become a popular city for duplex properties as many of them have basement with separate entrances.

you dont HAVE to have a doorbell camera as long as you have converage on your entrance

Depending on these regulations, you might need to maintain a means of exit from the basement unit, such as a separate entrance to the outside, or ensure that the stairs remain accessible but secure.

In Denver where I invest it's actually a PLUS to not have the other unit considered separate because permits are only allowed for STR if you're renting out your primary residence and I know many folks who put a locking door on part of their home and have a separate external entrance to that part of the house, and rent it out as an AirBNB without it being considered an additional unit by the city.

The owner shall also post a notice of intent to sell at all public entrances to the property (that form will also be provided by DOH).If the owner receives an offer from a third-party, the owner shall provide a written notice to the DOH, tenant association or to each tenant in the rental property.

They have been diagnosed ith bipolar disorder.Here in Virginia, there is a volunteer group that sets up at the entrance of the courthouse and they coach tenant's on what to say to delay evictions, or get the case thrown out of court. 

With its own exterior entrance, soundproofing, and hotel-like amenities, guests have a comfortable space without ever entering our living area.
