Examples of Commercial Building Depreciation
(These examples are not using remodel code and year which could also affect effective age.)

Class is structure class. The Class is in the NBC database, but in as a Moore table, pictured below.

In the case of this example the 45 year table will be used (based on occupancy, class, quality).

Effective age:
2022 (Working Year from County Information Table) – 1975 (Year Built) * .8 (Excellent Condition) = 38

Depreciation would then be 67%

Another Example

In this example, the 35 year table will be used (based on occupancy, class, quality).

Effective age:
2022 (working year from county information table) – 2009 (Year Built) * 1 (Average Condition) = 13

Depreciation would then be 22%.
