The connection referred to here is not the physical connection of the sewer pipe. It refers to allowing a dwelling unit to have its sewage transported by the City system and processed by the SASM treatment plant. The connection charge for second units is $1,250 for dwelling units less than 700 Square feet and $4,000 for units greater than 700 square feet. In addition, an annual Sewer Service Charge of $297 is levied on the second unit. The physical connecting of a second unit may also require a Plumbing Permit from the Building Department for work on private property and an Encroachment Permit for that portion of the work in the right-of-way.
