Water and Sewer Availability Letter

What does it mean?

Some financers require that a Water and Sewer Availability Letter be provided prior to the financer approving a loan. This letter identifies whether there is water and sewer available to the project site and which lines are not available for connection. Per the District of Columbia Building Code utilities are considered available if a residential lot is within 100-feet; a commercial lot is within 250-feet measured along the centerline of a street or public way abutting the lot.

This letter only advises you that water and sewer mains are available to service this project. This is not an approval to connect to these facilities or a certification that there is adequate capacity in these mains to serve the proposed development. A Water and Sewer Availability Certificate will be issued after the approval of the project plans and the payment of all the appropriate fees.

Does this apply to me? Your financer will ask for this if it is required.
When do I apply? As directed by your financer
