A landing outside every exterior door is one of the details an LADBS plan checker looks for on a Canoga Park ADU set, and the wide glass door onto the patio is no exception. The drawings have to show how far the patio sits below the floor, how deep the landing runs and how water stays out at the threshold. Get those right and the room opens onto its patio with barely a step.

A threshold that keeps water out

A patio laid flush with the floor looks clean, and it needs care at the door. We slope the slab away from the unit, set a trench drain or a gravel strip along the threshold, and choose a door with a sill rated for water. Where the floor sits a step above grade, the landing is poured as part of the patio so it never settles apart from the slab. Shade comes from a cover framed off the unit or a freestanding pergola, and its posts sit on their own footings shown on the drawings.

The rest of the LADBS review

Beyond the door details, the Canoga Park set goes through the same City of Los Angeles review as any ADU: setbacks measured on the site plan, the bedroom's escape window, smoke and carbon monoxide alarms, and the electrical load added to the main panel. If the yard has a pool or a large tree near the footprint, the drawings show the distance to each. We reply to plan check comments in writing and resubmit. Inspections run from the footing trenches to the final, and the unit can be lived in once that final is signed.
