Additions can be simple or very complicated projects depending on the work proposed.  The checklist below attempts to identify all potential documents that may be required. 

Depending of the size of the addition in comparison to the existing building some of the listed items may not be required for your project. 

Please contact the Building Department early in your design process if you are uncertain or require clarification of the building permit process.
