There may be other requirements, but those are the two I know about immediately with regards to Midvale City.I would strongly recommend you check into the zoning code on this proposal. 

Let me propose to you a slightly different method to approach your DMM/PPC/FB ads campaigns. 

Quote from @Vance Sander: Hi -I have an upper end condo in Los Angeles that rents towards the top of the market. 

Yes, the buyer does not own the property so cannot give a notice, but the seller has the  right to give notice given the buyer has proposed they do intend to occupy.

I work as a civil engineer here in Austin, and what you're proposing can be done but it's not always simple.

Do you have a solid proposal/estimate from a Contractor or are you guessing at the $70k?

I am expecting the property to appreciate aggressively within the next decade while the rent I we are currently getting there is like peanuts.I have proposed to the current tenant to increase the rent else he will have to vacate and awaiting for his response. 

Their minimum standards will most likely surpass your local zoning & site built proposals.

Since this is an over time thing the strategy can be more complex.You need a commercial real estate attorney that is familiar with the process.Most commercial brokers and agents what you are proposing is too much work for them versus a traditional transaction that happens all at once.Good luck.

So pick a structure that you're comfortable with and make a proposal to him.
