The kitchen doesn't have requirements unless there's WC clearance issues because residents don't cook or use the kitchen.Are you going to run the business too or just modify the home for that purpose and sell it?

In MA, property owners are REQUIRED to bring a property into a lead safe condition (called compliance) if a child under the age of 6 resides in the house/apartment. 

She will use part of the house as her residence as well.

@Chatree C.You will need to find a Solo 401(k) plan document provider and then you can have the funds reside at the custodian that you mentioned or at a local bank if you prefer.The Solo 401(k) provider will also assist with the ongoing compliance requirements such as filing form 5500-ez when needed, processing plan updates and  also answering technical questions regarding the rules and regulations.Regarding UDFI, this tax generally does not apply to the Solo 401(k) plans.

It is in an area that zoning works out (currently mixed use commercial + primary residence SFH) and is 'up and coming' by encouraging density.

My goal:With our busy full-time schedule, My spouse and I would love to do a live-in flip on a primary residence or BRRRR, I think the latter is the best for us.

The property is located in Florida (In case that makes a difference) and does reside in an association area/neighborhood.

When looking to purchase commercial real estate land / property (I reside in Utah), what are the necessary questions to vet out with a real estate agent?

So after that, I kept a careful eye on the number of residents living there, and water usage actually went down.So before you go crazy about residential vs commercial, sub-metering etc, have these issues checked out.
