Besides meeting commercial codes, such as parking, handicap access, etc, is there any other things I should consider?  

I was 40 years and 7 months in August of 2016 when we closed on this building:The price was right, the location is great, and it had a lot going for it including:1) The prior owner had put very high end furnaces in fairly recently.2) The siding, windows, and doors were all 5 years old.3) Handicap accessibility to the two largest offices.4) Parking for 20 in a town that has very little parking.There were some issues to resolve, however:1) The roof in the picture is the new roof that we had put on.2) The building was vacant.

That would handicap me for improvements and other properties.  

My west-side knowledge is fairly handicapped.

Title VIII of the Civil Rights Act of 1968, as amended, prohibits discrimination in the sale, rental, and financing of dwellings, and in other housing-related transactions, based on race, color, national origin, religion, sex, familial status (including children under the age of 18 living with parents of legal custodians, pregnant women, and people securing custody of children under the age of 18), and handicap (disability).Better take a landlord class and get your act together.

I would want all future tenants to pass unless they are under defendant care like someone one is handicap.   

The building department could require handicap accessibility, sprinkler systems, fire exits, adequate restrooms to support 100+ people, etc.

As long as you're not discriminating against someone based on race, color, religion, sex, national origin, familial status or handicap, you won't run afoul of the federal Fair Housing laws.

Emotions are a  business handicap.

We gave her another 5 days, then she says apparently she is handicapped, and she lost her job, and she just had surgery and wants more time.
