A Build Over Agreement is permission from your local sewer authority to build over or near a public sewer. It’s like asking a grumpy neighbor if you can park your car on their lawn. Only here, the lawn is a massive pipe that carries everything you flush.
If you ignore this agreement, you might end up with a collapsed sewer line. That’s fun for no one. Especially not the guy who has to fish your lost wedding ring out of a sludge pit.
