You are correct we are not permitted legally to disagree in public however the courts have made special exceptions in regards to the interweb.

Also, when you're deciding where to move mobiles to, check on what government body issues move-on permits.

You cant move your mobile home out of the park normally because of issues (high prices for trucking, etc)and permits(size limits and new laws are always changing) to move them on the highways, other parks normally have guidelines of newer years of mobile home or larger sizes which are the newer mobile homes (normally not the ones you got the deal on) causing many problems.Anyhow, with my experiences i sold my two mobile homes and began to buy two and three unit houses in my area.

I'm not in your area but I suggest you go down to the permits department and speak with someone there, in person.

It sounds like the back unit may be a problem too, if only permitted as a garage, but has a kitchen and bath etc.

3- Landlord could be fined for violating zoning/building permit requirements.

So please if there is a #contractor, #real #estate #attorney or #architect that understands #permitting in #DC please respond. 

But if it looks like a D house, and smells like a D house....As far as the duplex convenience store, if it bothers you, call the city and tell the tax people that there is someone selling stuff without a sales tax license, and operating a business without a permit. 

I've heard an (2022)  estimate cost of a few thousand to ten thousand for installation and permitting.

The city has been very responsive on getting back on if a property is eligible for a permit, which has helped speed up the process.
