Why Choose Homewerx?

ADU Code Is Different

San Diego's ADU plumbing code requires independent shutoffs, properly sized supply lines, and separate drainage — even for attached units. Non-compliant installations fail inspection and cost thousands to redo.

Shared Sewer Lines Create Risk

Connecting an ADU to an existing sewer lateral doubles the load on pipe that may already be 40+ years old. Camera inspection before construction prevents sewage backup surprises after move-in.

Water Pressure Splits Between Units

Adding an ADU splits your water supply pressure between two households. Without proper line sizing and potentially a booster pump, both units suffer weak flow at peak usage times.

Permits Protect Your Investment

Unpermitted ADU plumbing can void homeowner's insurance, create liability issues, and tank your property value. We handle the permit process and ensure every connection passes inspection.

Our Process

01

Site Assessment

We evaluate your existing plumbing capacity — main line size, sewer lateral condition, water pressure, and available tie-in points — before any design work begins.

02

System Design

Custom plumbing layout optimized for your ADU floor plan. We size supply lines, drainage, and venting to meet code while maintaining performance in both the main home and the new unit.

03

Permit & Plan Submission

We prepare plumbing plans for permit and coordinate with the city of San Diego's building department. Our plans pass review the first time because we know the current code requirements.

04

Rough-In Installation

Supply lines, drain-waste-vent piping, and fixture connections installed during the framing phase. We coordinate with your general contractor to stay on schedule.

05

Fixture & Appliance Connection

Final connection of all fixtures — sinks, toilets, showers, water heater, dishwasher, and laundry — once walls are closed. Every connection is tested for leaks and proper flow.

06

Inspection & Handoff

Final city inspection, pressure testing, and a complete walkthrough with you covering shutoff locations, maintenance schedules, and warranty details.
