As more and more rules and regulations are imposed on mobile home park and lot developers the responsibilities for getting a mobile home properly set up have become more difficult and expensive. Since obtaining a loan to purchase the property depends on meeting all these requirements, mistakes can be expensive.
The entire mobile home setup process now takes much longer than it used to. Permits must be acquired in the proper order; the electrician can't do his work until the foundation guy is done, etc.
Setup is done by a crew that may work for the dealer but in many instances is a separate subcontractor. Since they are paid by the job there is a lot of pressure to get done quickly. Since most homeowners will never crawl under their homes to look around and wouldn't know what to look for if they did, the setup mistakes are not noticed until they cause problems. By that time warranties have expired, companies have disappeared and the homeowner is stuck.
