Often you can look up the city’s zoning ordinances online and review all the rules such as dwelling units per acre, front/side/rear setbacks, etc. 

Firing the disinterested party (me) was the most humane thing I could do!

If he wants to call the Fairfax County Human Rights Commission, he has the right.

@LeAnn Riley -I think you may have wanted to link this as it gives the specifics.Conversion-to-Three-Unit-Dwelling---Common-Code-Rules.pdf (minneapolismn.gov)@Brady Mickolichek

(a) A landlord may enter the dwelling unit only in thefollowing cases:(1) In case of emergency.(2) To make necessary or agreed repairs, decorations, alterationsor improvements, supply necessary or agreed services, or exhibit thedwelling unit to prospective or actual purchasers, mortgagees,tenants, workers, or contractors or to make an inspection pursuant tosubdivision (f) of Section 1950.5.(3) When the tenant has abandoned or surrendered the premises.(4) Pursuant to court order.

You depreciate the actual COST of the dwelling structure even if the value is higher than what you actually paid.For the homeowners insurance, be careful.  

If they will not, contact an independent agent who represents multiple companies and see if they can find you a Homeowners that will also extend Liability for the rented dwelling.

Major structural components of the dwelling structure (roof, windows, HVAC, water heater, etc) have the same 27.5 year class life as the dwelling structure itself.Sounds like your accountant is on top of everything.

Determine the cost basis for the dwelling structure as the purchase price of the property minus the value of the land.  

You must capitalize those expenses, then recover their cost through depreciation of the dwelling structure.
