Construction Costs

Determine Costs

The steps to determine construction costs are:

  1. Determine the construction’s use or classification from the first table.
  2. Determine the type of construction (use the second table to figure construction type).
  3. Determine the cost per square foot of the construction from the first table by matching the classification with the type of construction.
  4. 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 $85

Then we use that value to find the construction cost:

  • $85 per square foot x 2,000 square feet (home size) = $170,000 (construction cost).
  • This number, $170,000, is now used to calculate the Building Permit Fee
