Type of work

Type of work section has four options: New construction; Demolition; Addition/alteration/replacement; Other. Select one of the options that applies to your project.

The Type of work section has four options. This section is required. Select one that applies to the project: 

  • New construction: Are you building something that does not exist now? Are you getting a permit for a structure that does not have any permit records? If yes, select this option.
  • Demolition: Are you tearing down or removing an entire structure? If yes, select this option.
  • Addition: Are you adding to an existing structure? Are you creating new space as part of an existing structure? If yes, select this option.
  • Alteration: Are you altering the interior walls of an existing structure? If yes, select this option.
  • Other: Are trees are being removed or grading taking place? Or, something else not covered by the other selections? If yes, select this option.

Example: 

You want to build an addition to make your home bigger. As part of this project, you’ll need to tear down a weight-bearing wall. Although you’re removing walls, you’ll want to select addition. This is because you’re not removing the entire house, you're adding on to it.
