Lot value includes site improvements such as well, septic system, water, sewer, landscaping, and driveway. A lot without site improvements should first be valued as if the lot had site improvements and then the assessor should deduct for the absence of site improvements by either percentage or dollar amounts. If a structure is built to house a solar heating or cooling unit, there may not be additional assessment for these structures. If this structure has a dual use such as storage, only the value attributable to the use other than solar heating and cooling shall be assessed. The valuation of subdivided land should consider each lot as a single legal entity regardless of ownership. When real property is revalued because substantially completed improvements have been made adding at least the statutory minimum in value to the property under Tax-Property Article, §8-104, Annotated Code of Maryland, both the land and improvements shall be revalued on the date of finality, the semiannual date of finality, or quarterly date of finality following the substantial completion.
