Construction Costs
Determine Costs
The steps to determine construction costs are:
- Determine the construction’s use or classification from the first table.
- Determine the type of construction (use the second table to figure construction type).
- Determine the cost per square foot of the construction from the first table by matching the classification with the type of construction.
- Take the cost per square foot and multiply by the building’s square footage.
Example
- Group R-3 One Family Home
- VB Construction Type
- Building square footage is 2,000
Using the tables:
- Classification would be Residential, one family
- Construction type would be VB (combustible and non-rated)
- Using the chart, from the Residential one family row and the VB column, we find the minimum cost per square foot is $122
Then we use that value to find the construction cost:
- $122 per square foot x 2,000 square feet (home size) = $244,000 (construction cost).
- This number, $244,000, is now used to calculate the Building Permit Fee
