What if I have an existing house that I want to replace or add on to?

If you are not increasing the number of bedrooms and the addition does not encroach on the septic system or well, you will need to apply for an Existing System Authorization. You will need to submit the application along with a floor plan and site plan. Our office will visit the site and if there are no problems, will issue the authorization before the building permit can be issued.


If the number of bedrooms is increasing, or the septic system needs to be relocated, you will likely need to apply for an Improvement Permit and Construction Authorization. Please talk with one of our staff to make this determination.
