Better to beg forgiveness than ask permission here.

You need to go to planning and zoning first to make sure it's zoned for what you want to do and if permissible, obtain the proper permits.  

Local zoning and planning departments are the primary sources for this information.Engage a Surveyor: If the subdivision is permissible, the next step is to hire a licensed land surveyor.

@Mehul RupaniYou might look into whether the missed depreciation would be treated as an error and rectifying by filing an amended return.I believe a 3115 is only filed if a method was adopted/established (by consistent treatment on at least 2 consecutive tax returns) and you will be changing the method from an impermissible to permissible method.Wouldn’t recommend DIY in this area, it’s pretty technical and the full facts should be reviewed by a tax professional or offer proper advice before taking any action.Hope it helps

Sometimes asking for forgiveness instead of permission is not something that you should do in this case. 

You should ask for their permission before installing.

On the STR side I focus on the coast and the target is narrowing, more restrictions or limited areas of permission and permitting, but still ample opportunity and worth the 'hassle.'

If I were the other tenant asking for permission to get a cat, it would almost be a little discriminatory since my other roommate was allowed two pet cats.

In normal circumstances the rentee stands stronger than the renter in the sense that the renter doesn't have the permission to be cancelling a contract during the length of the contract if it isn't for any force major reasons (for example, he/she is selling their apartment).

I contact other agents for permission to advertise their listings with the hopes of finding a buyer or lessee.
