Salt Lake County has revived a proposed ordinance amendment that would allow mobile homes to occupy individual lots throughout the county and require them to meet the same code standards as conventional houses.

The county's Planning Commission voted earlier this month to recommend the proposal be rejected, saying it was unenforceable and would violate the spirit of zoning ordinances.But county commissioners Wednesday set a May 10 date to hear an appeal of the Planning Commission decision filed by two local mobile home dealers and a mobile home owner.

Under current ordinance, mobile homes are prohibited in Salt Lake County, except in parks or subdivisions specially designated as mobile home locations.

The proposed change would allow a mobile home to occupy any vacant lot in the county if certain conditions are met. Commissioners had agreed to consider, but not necessarily to approve, such an amendment as part of the settlement of a 1987 court challenge to the current ordinance filed by the mobile home industry.

The appeal calls the current ordinance discriminatory to manufactured housing and contends it violates the U.S. and Utah constitutions.

The proposed amendment would require mobile homes, modular homes or any manufactured housing placed on a lot to meet the same subdivision, zoning, flood control, building code, fire safety and health standards that apply to all conventionally built homes.

It also would allow owners of mobile homes now illegally occupying lots outside designated parks to become legal occupants if they meet certain standards. Those owners would be required to meet by 1991 the codes that were in force when the mobile home was first illegally placed at its present location.

In addition, the proposed change would tax mobile homes as real property rather than as personal property as they now are taxed.

Herriman-area mobile home dwellers had opposed the change, saying meeting the new requirements would cost so much they would have to give up their homes. They saw the amendment as a plot by county officials and residents of a nearby exclusive subdivision to remove mobile homes from the Herriman area.
