Toluca Lake ADU Construction, Starting at the Slab

Toluca Lake ADU construction that starts with a moisture test on the garage slab, then weighs a conversion against detached, attached and JADU options.

Moisture rising through an old garage slab is the first reading we take on a Toluca Lake lot, with a sealed test kit taped to the concrete for a few days. That result tells us whether a conversion can take flooring as it is or needs a vapor barrier and a new topping. It also feeds the comparison we build across the four ADU types, since a dry, sound garage can tilt the choice away from a detached unit.

Reading the rest of the lot

After the slab, we measure the garage's clear ceiling height, the width of its door opening and the distance from its walls to the property lines. A detached unit gets its own check: the open area behind the house, the location of the sewer line and the path a truck or a pump hose could take. For an attached unit or a JADU, the walls and rooms of the house are what we measure, including where an outside door could go without cutting through a bearing wall. Every one of those readings goes onto the side by side sheet.

Conditions on an inland Valley lot

Toluca Lake sits within the San Fernando Valley, and the conditions we plan around there are the general inland ones: hard sun, dry wind and now and then a heavy rain. A converted garage gets wall and ceiling insulation it never had, a reflective coating if the old roof stays, and a mini-split head sized for the room. On a new detached unit, deep eaves and a gutter sized for a cloudburst protect the walls. Lots in Studio City, North Hollywood and Burbank get planned the same way, with each city's own permit rules applied.
