The County does not make it easy to look this stuff up which, in my mind, should be under a FAQ list but I am still confused.  Here is the "applicability section and I can't find where it says one junk vehicle is allowed in front yard.

(b) Prohibition. Except as herein set forth, after April 1, 1990, it shall be unlawful to possess any junk vehicle or vessel or major assembly component in Worcester County for more than thirty days in any one calendar year.

(c) Applicability. This section shall not apply in any of the following cases:

(1) In the incorporated areas of Worcester County.

(2) To any junk vehicle or vessel or major assembly component thereof which is located in a properly zoned area in conjunction with a bona fide legally maintained dealership, junkyard or repair facility or on any property pursuant to a duly granted permit under § ZS1-328 of the Zoning and Subdivision Control Article of the Code of Public Local Laws of Worcester County providing for transient uses.

(3) To any junk vehicle or vessel or major assembly component thereof which is maintained within a completely enclosed structure or completely screened from view from any adjacent property or road by a fence or other enclosure.
