I’ve been thinking about the possibility of a Manufactured ADU.

Most manufactured homes should be on concrete blocks, whether it is a permanent foundation or a set of piers usually about 3 blocks high.

The air conditioner manufacturers are going the way of the automotive company's so you have to use their parts on newer equipment coming out.

Our firm is considered the manufactured housing industry authority on the SAFE Act, and we have done hundreds of speaking engagements on the subject at MHI, state associations, and the major buyer's groups since the model legislation was proposed, and we can't do it in an hour for one state, let alone for 50 states - the laws vary somewhat from state to state.In addition, the SAFE Act is only the tip of the iceberg regarding the laws, rules, and policies those engaged in seller financing must deal with.

EX: You're a manufacturer that makes ABC widgets, now your biggest customer wants you to make XYZ widgets, you can set up a job that tracks the performance of the new XYZ widget - for that customer.With classes, you simply designate a class (ex: Brick House, 123 Main St.) with any/every tranaction that is associated with it.

Intel is a great example, who is building the largest chip manufacturing plant in the US right here, and it will be a $20 billion dollar investment that brings a few new thousand jobs.https://www.dispatch.com/story/business/2022/01/21/intel-ohio-building-computer-chip-factories-licking-county-jersey-township/9173472002/ Another example of economic growth is the upcoming Ohio State University Wexner Medical Center Inpatient Hospital which is a 1.9million square foot hospital that will bring over 800 new beds and a thousand new jobs. https://abc6onyourside.com/news/local/new-osu-hospital-expected-to-transform-health-careHere are a few more recent investments https://www.10tv.com/article/money/business/hydrogen-power-company-hyperion-bringing-700-jobs-to-columbus/530-25907aab-5517-4661-a9f3-d2ed2d5be6b0 https://news.wosu.org/news/2022-02-08/rumpke-to-build-50-million-recycling-facility-in-columbus Check out The Complete Guide to the Columbus, Ohio Real Estate Market which goes through the Columbus, Ohio market in depth and will give you a better scope of where the highest levels of growth are taking place and where to look to invest.

Is this a small possession by a potentially (petty) Police Officer 7 years ago or are we talking about someone running an absolute grow shop out manufacturing and distributing out of their residence?

Delta, Kohler, Simmons, and the like are solid fixtures that you can actually get repair parts for and usually for free from the manufacturer. 

It's an 'oops' by the manufacturer 1/4" less narrow than specs.  

The best plug I could give is the economic diversity, from high tech to tons of distribution centers and manufacturing.
