ADU Construction in Mar Vista, placed by the drain line

Backyard ADUs in Mar Vista placed around the house drain, with a wide glass wall onto a shaded patio and frames chosen for damp air near the coast.

Our locator traces the house drain across a Mar Vista lot before any outline goes down. Where that line leaves the foundation, and how deep, decides how far back a new unit can sit and still drain by gravity. A deep exit frees the rear corner for a studio with a wide glass wall and a shaded patio of its own. A shallow one draws the unit closer to the house, and we shape the light around that.

Light and drainage on a Westside lot

Once the drain route is known, we turn the unit so its big opening faces open yard and away from the main house windows. Each home on the lot then keeps a view of its own. Near the coast, damp air reaches metal and wood, so we pick fiberglass window frames, stainless fasteners and a factory finish on the door track. If the drain sits too shallow for the brightest spot on the lot, a small pump basin is one fix, and we weigh it against moving the unit closer to the house.

Permit review through LADBS

Every inspection on a Mar Vista unit, from footings to final, is signed off by LADBS, the building department for the City of Los Angeles. A parcel this near the coast may or may not lie inside the state coastal zone, and we look that up by address before drawing, since a lot inside it can need a coastal approval too. The side and rear setbacks come from state ADU law, and the plan checker holds the site plan to them. We coordinate the engineering and the Title 24 energy work, file the set and answer each correction until the permit is issued.
