Are you building an Accessory Dwelling Unit (ADU) on your property in North County San Diego? Whether it’s a rental, guest house, or granny flat, one of the most important - and often overlooked - steps is connecting your new ADU to the city sewer system.
We specialize in ADU sewer connections that meet all California plumbing codes, and we’re licensed to work in the public right of way, where many connections must be made. That makes us one of the few contractors in the region qualified to handle the full scope of sewer work for your ADU project.
Why Sewer Connections for ADUs Require a Qualified Contractor
Installing or extending sewer lines for an ADU isn’t a simple backyard project. It often requires digging into public streets, sidewalks, or easements to reach the city sewer main. This work:
- Requires permits and inspections
- Must meet strict California and city-specific plumbing codes
- Can only be done by a contractor approved to work in the public right of way
We are a fully licensed general contractor serving North County San Diego, and we are permitted to perform sewer work in streets and other public areas. That means we can manage the entire sewer connection process - from permitting to trenching to inspection - with no third parties or delays.
