When converting your basement into an ADU or adding a kitchenette, the plumbing requirements focus heavily on the basement plumbing rough-in. This process is a critical budget and planning item that depends on several technical factors specific to your home’s existing layout:

• Waste Line Elevation: We must determine if your waste lines are located above or below the sewer lateral. This dictates whether a standard gravity drain or a specialized pump system is necessary.
• Fixture Proximity: The cost and complexity of the installation are influenced by how far your new kitchenette sink and appliances sit from the existing plumbing stacks.
• Municipal Compliance: In areas like Denver, Littleton, and Centennial, all plumbing work must comply with local building codes and requires a building permit.

Because these factors vary significantly based on your home’s foundation and existing utility locations, we recommend an on-site evaluation. This allows us to provide a custom quote that accounts for the specific structural and mechanical needs of your project.
