ADU Construction in West Hills with a tilted roof
West Hills ADU construction with a roof that tilts up toward the patio for tall glass, and rain led off the back edge into a planted swale.
Tilting the roof of a West Hills ADU up toward its patio buys height for tall glass on that side and sends every drop of rain to the opposite eave. A gutter at that low back edge collects it, and a single downspout carries it into a gravel basin or a planted swale set away from the footings, so the patio side stays dry and clear of pipes.
Roof, gutter and the setback
The low back edge sits near the rear setback, so the gutter and downspout have to keep water on our side of the line and out of the neighbor's yard. We size the gutter for the full roof area, add a leaf screen, and pitch the ground around the unit away from the walls for the first few feet. At the high patio side, a deep overhang shades the glass and throws only a little water, which lands on a gravel strip at the patio's edge. Covering choices include a light-colored membrane or standing seam metal, and both shed inland heat well.
What LADBS checks
A West Hills ADU is permitted by LADBS, and the plan checker follows the roof drainage along with the rest of the set: setbacks, the bedroom escape window, the structure over the wide opening and the load on the main electrical panel. A roof pitched this way also has to stay under the height limit for a detached unit, which the drawings show on a section through the high side. Inspectors visit from footings to final, and the unit is ready to live in after the final sign-off.
ADU Construction in West Hills: what people ask
We put the unit where its tall patio wall faces the most open part of the yard and its low back edge sits toward the rear line. That keeps its glass looking at garden, puts its roofline below the main house's view, and leaves room for a planted strip between the two patios.
Kept to one level and 500 sq ft or less, a West Hills ADU fits it. The wall drawings for a West Hills unit with a tilted roof show the tall side, the header over the glass and how the height stays inside the limit. Anything taller or bigger gets its own quote after we see the lot.
It can, and the high side of the roof is built for it. Tall sliding or folding glass fills that wall, the overhang shades it, and the patio steps down only slightly from the floor, sloped away from the door so rain from the overhang runs off toward the gravel edge.
