@Dustin RuffI'll say, I've never heard that even proposed and first inclination is no but only an electrician would know exact code or could check with a state inspector.

There has been new legislation in LA regards notice and where and to whom it will apply.

She has also proposed me going into the property with her at 20% and her business will rent out garage from me.

The deal you proposed would NOT make sense if you want cash flow.If you're looking for appreciation in the Taunton market, obviously that's a gamble. 

As far as dogs go, breeds matter and the type proposed is a good one for the landlord. 

My question is this how would one propose 1) A new rate and secondly, if the lease agreements are now month to month, here in Minneapolis are their guidelines in place that would prevent me from increasing this rate to a more landlord friendly price point.

Depending on what you're trying to accomplish, the route is probably going to be either a TIC with your partner or a single LLC taxed as a partnership with you contributing the property for unit interest and your partner contributing cash or services for unit interest.What you propose above will most likely incur thousands of dollars in legal and CPA fees in year one. 

The Rent you propose is almost 61% higher.Joe

The staff planner that is assigned your formal application submittal will analyze your proposal against the goals and policies of the adopted General Plan and associated Zoning Ordinance development standards.

Both Portland and South Portland have made rules and legislation to curb short term rentals (1 month or less).
