ADU Construction in Reseda, Placed by the Sewer Line
Reseda ADU construction placed by the house sewer line: how deep it runs decides where a detached, attached, garage conversion or JADU unit can drain.
Somewhere under a Reseda lawn the house sewer line runs toward the street, and its depth where it leaves the house governs how far back a unit can sit with drains still falling to it. A scope camera and a pipe locator find that depth on our first walk of the lot. A garage conversion or an attached unit near the line keeps the hookup short, while a cottage at the far fence may need a pump.
Sewer depth and the four types
Smaller drain pipes need a quarter inch of fall per foot of run, so every foot of distance costs depth. A JADU drains into plumbing already in the house. An attached unit ties in close to where the line exits the foundation. A garage conversion depends on whether its floor sits above the line once the trench is dug. A detached unit at the back of a long yard is the case most likely to need a deeper trench or an ejector pit, and that pit adds equipment, a dedicated circuit and an alarm to the scope.
Water, power and sign-off
Water reaches the unit through a branch off the house supply, and we read the pressure at the hose bib beside the planned footprint. An electrician totals the house's demand against the panel rating to size the feeder. LADBS reviews the plumbing layout with the rest of the drawings, and the sewer connection is inspected with the trench still open. Once the inspector signs the closing card, the Reseda unit is legal to occupy and its first tenant or relative can move in.
ADU Construction in Reseda: common questions
Each of the four can work where the setbacks allow it. We lean toward the type whose drains reach the house sewer by gravity, and we show the cost of each, so a cottage, a conversion, an attached unit and a JADU get compared on the same terms before anything is drawn.
LADBS takes the Reseda ADU set on behalf of the City of Los Angeles. Here the site plan carries the sewer route and its tie-in point, and the floor plan places each fixture, which lets the reviewer confirm the drains can fall. Our office files the set and replies to each round of comments.
Yes for the parking, since state law stops Los Angeles from requiring replacement spaces when a garage is converted to an ADU. Whether the conversion is worth doing rests on the slab, the framing and how the new bathroom drains, all of which we check before recommending it.
