Looking for proper steps to see if mobile home is an option

[Mark Beekman]

I'm looking to put a mobile home on a vacant residential lot that I own (all utilities are present and ready to be hooked up). Zoning allows for mobile/manufactured homes as long as there is a concrete foundation to strap it to, unless the manufacturer suggests an alternative way to secure the home.

The lot suffers from soil subsidence issues, however, so I'm not even sure that a foundation can be put in (see this thread for more info: "Building on Junk Fill"). The Township won't answer any of my questions and basically just tells me to submit a building permit application so they can say "Yay" or "Nay".

I'm brand new to the process and don't know what my first step should be. The application is also a bit over my head. Do I go directly to a mobile home manufacturer and have them take care of the application? Do I piecemeal things out to an excavator, concrete company, and mobile home manufacturer?

I'd hate to waste everyone's time and energy just to find out that I can't put the foundation and mobile home in, but it seems like the only way. Anyone here that can nudge me in the right direction?
