I know there are a lot of rules a SDIRA needs to follow to fully take advantage of the tax benefits and make sure you are in compliance. 

Some general “Rules of Thumb” from 25+ Years as a Residential Agent & Broker.

In your pre screening you ask:1) Do you presently have a pet of any kind.2) Do you foresee acquiring a pet of any kind during your tenancy.3) Is there any possibility you may need to pet sit someone else's animal.You then inform them that if any animal is found to be in, or has been in, the unit for any reason they will be evicted or assessed a $1000 fee for every occurrence on a per day  bases.Some are stupid but most applicants believe that landlords are so desperate and so dependant on needing a tenant asap they think landlords will ignore their own rules to accept a good applicant.

A question I have is if it is a relative safe assumption or general rule of thumb, used in a quick analysis scenario, that if a property has a Certificate of Compliance with the City that the MEP has been inspected and is up to code.

That would be theft.You will be much better off finding an attorney or advisory firm that can integrate the LLC with the overall IRA setup & administrative services and meaningful consultations related to maintaining compliance with IRS rules. 

Under Fort Worth, TX rules, if community home is up to 6 residents + 2 caretakers, it is not rezoned, it's still stays residential. 

. :)The deal with the 100 mile rule is only applicable if deriving rental income from the departing residence is needed to make the numbers work.VA - will count departing residence rental income once you've got landlord experience.FHA - will count departing residence rental income in very rare circumstances that aren't applicable to most people. 

The new rules are draconian. 

But as a rule of thumb, I would take a look at your city's zoning code or call up the building department and ask how many parking spots are required per unit.

You'll find out how they "should" be handled by the board and then you can hold them accountable for following said rules or be in legal jeopardy for not following their own bylaws.
