    DEPRECIATION

    Log Homes are residences with log exterior walls. Log homes are usually precut and packaged kits, erected using skilled labor for construction and installation of fixtures. The finished structure will conform to building codes and is often used as a primary residence. Log homes have been found to be somewhat more costly than similar-quality homes of a more conventional nature. For amateur workmanship, costs should be reduced by 15% to 30% to reflect primarily unsupervised, unskilled labor.

    Log homes are categorized into four different classes, CD through B. Basic descriptions, photographs, and specifications are provided for each of these qualities.

    Photographs are intended to illustrate the general characteristics of this type of residence in a given class.

    The square foot costs include: Kit assembly and installation on a reasonably level site; finished interior with kitchen and bathroom; basement; forced-air heating.

    The square foot costs do not include: Public sewer connections; appliances; drapes; garages; and other optional items.

    For adjustments and additions for other than basement, please refer to the corresponding site-built adjustment and addition pages.

    For log sizes other than 6” diameter, add the following: Pine

    Example: Adjustments for a Class CD Log Home can be found in the Class CD site-built section, Page 52. A pricing example is included at the end of the section.

    For log wall garages, please refer to the corresponding site built garage pages and add 15% to the siding cost. Example: The cost for a 440-square feet, Class C, log- wall detached garage with 18" footings can be found on Page 70. The cost per square foot for 440-square foot of siding is $30.15, which, multiplied by 1.15, gives a cost of $34.67 per square foot for the log wall garage.

    Depreciation schedules can be found on Page 156.
