A nonconforming use is a use of land, buildings, or structures that was lawfully established prior to the effective date of this ordinance, or any amendment thereto, but which does not conform to the regulations for the zoning classification in which it is located.Nonconforming uses may be continued subject to the following limitations:a) No nonconforming use shall be extended, expanded, enlarged, or moved to occupy a different or greater area of land, buildings or structures than was occupied by such use at the time it became nonconforming; provided, however, a nonconforming use may be extended throughout any parts of a building which were specifically designed and arranged for such use at the time it became nonconforming.b) No building or structure devoted to a nonconforming use shall be enlarged, extended, recon­structed, moved, or structurally altered unless such building or structure is thereafter devoted to a conforming use; provided, however, such building or structure may be enlarged or extended upon prior authorization from the Board of Adjustment, which authorization shall not be granted unless the Board of Adjustment makes each of the following findings of fact:1) The proposed enlargement or extension shall be de minimis in relation to the existing building or structure.2) The proposed enlargement or extension shall not increase the intensity of the nonconforming use, which is to say, it will not result in an increase in dwelling units for a residential use nor in gross floor area for a nonresidential use.3) The proposed enlargement or extension is designed so that it will not render the use of the property any less compatible than it is in its existing circumstances.4) The authorization of such proposed enlargement or extension is not otherwise contrary to the public health, safety or welfare.c) A nonconforming use of a structure may not be changed to another nonconforming use unless such change is authorized by the Board of Adjustment.

@Jared Garay, how much does your current living arrangement cost you per month?  

FIL passed away, and we were dealing with the funeral arrangements.

We are buying the property with contingency that Seller arranges for tenants' temporary move-out & compensate them for the inconvenience.

She backed down right away, but ya just gotta be careful with some people, always trying to take advantage.....I suppose I'll rent to her again if she asks, but go over the arrangements again.

We are at a point of discussing alternative living arrangements.

I've lived off the grid with only solar and propane and as an owner that's NOT going to be successful as STR unless you live on site and can constantly be repairing, cleaning, placing flower arrangements, and seeing to the needs of your guests. 

I thought this was beyond generous yet the seller refused this demanding to not pay.I hate to see a deal fall through for such a relatively small amount but my gut says if they made a big deal over something so reasonable imagine the issues once the deal closes and I technically become their landlord.Well anyway, I was curious what is the going arrangement for lease backs in a hot market? 

But look for this type of arrangement and co-op.

I think I will arrange to get the HVAC bid done with the inspection as it's a pivotal addition for me.It does make sense that contractors would have found creative ways to work around it.
