COMPUTER ASSISTED COSTING MODEL

Computer Assisted Mass Appraisal (CAMA) is an automation technique to assist in the valuation of real property. The Maryland Assessment Manual is used as a guide in developing current building costs. The manual is based upon 2000 construction costs.

A property valued by Computer Assisted Mass Appraisal will be computed based on the following square foot formula using perimeter cost, square foot cost, and constant cost for the particular structure type.

Formula for primary house type (Area 1) is:

Constant Rate
plus
Square Foot Rate times Square Feet in Section 1
plus
Perimeter Rate for Construction times Section 1 Perimeter
divided by
the Area of Section 1
equals
the Square Foot Rate for Section 1

If a dwelling has additional areas of different construction types, the following square foot formula will be used. The Formula for Area 2 and above is:

Constant Rate
plus
Square Foot Rate times Total Dwelling Foundation Square Feet
plus
Perimeter Rate for Construction times Total Dwelling Perimeter
divided by
Total Dwelling Foundation Square Foot Area
equals
the Square Foot Rate for the Section
times
the Square Footage of the Section
equals
the Cost for the Section
