Can the landlord of a mobile home park tell you who can live with you if you own the mobile home?

In some cases , yes. -For instance there are many "Senior Citizen " Parks, where every tenant is expected to be over 65. -If your case is of this type, and you signed an agreement to that effect, then he can reasonably object to younger tenants. -If that's not the case, then you should consult your local, Provincial or State office that protects Residential Tenant rights. Where I live, in BC, Canada, we have Two Acts of Provincial Govt. to deal with these rights. -The US is so progressive, I am quite certain they will have similar acts.
