Accessory Dwelling Units have become one of the most actively developed project types in Los Angeles over the past several years, driven by state legislation that streamlined the permitting process and a housing market that makes ADU rental income highly attractive for property owners. With this wave of new construction has come significant demand for plumbing services related to ADU additions, garage conversions, and backyard structure builds.Coast to Coast Plumbing handles plumbing for ADU projects throughout Los Angeles, from initial assessment of the main home's sewer lateral capacity to accommodate a second unit, through rough-in plumbing during construction, and final fixture connections and inspection. The team is familiar with the City of Los Angeles ADU permitting requirements and can work within the project's timeline.A critical early step in any ADU project is confirming that the existing sewer lateral has sufficient capacity for the additional fixture unit load. A camera inspection of the lateral and a review of its diameter and condition provides the information needed to determine whether the lateral can accommodate the additional unit or whether a new connection or upsized lateral is needed.Coast to Coast Plumbing | 3045 Larga Ave, Los Angeles, CA 90039 | +13102755800
