Here is the place for some real due diligence. Local zoning ordinances, shoreline regulations and storm water controls put in place by local jurisdictions to comply with state and federal requirements may make your project unbuildable on your particular piece of property.
Before you sign any contracts with builders or manufactured home providers, be sure to get a feasibility study done on your property. A good feasibility study will uncover all these regulations and let you know how long it will take to get required permits.Some jurisdictions can take up to one year for a permit if there are a lot of land issues connected with the property.
