ADU Construction in Agoura Hills, Roof First
ADU construction in Agoura Hills with a simple roof that sheds leaves and rain, guarded metal gutters, a Class A covering and drainage clear of the slab.
Fewer valleys and hips mean fewer places for dry leaves to pile up, so the roof we draw for an Agoura Hills ADU is a plain shape that sheds litter as easily as rain. Water leaves the low edge into a metal gutter capped with a metal guard, then drops through downspouts to a splash block or a buried line that carries it clear of the slab. The state fire map covers parts of the city, and every piece of that path is noncombustible.
A roof covering built for embers
A Class A assembly is the standard for the roof covering once the parcel lands inside a mapped zone. Standing seam steel, clay or concrete tile and certain asphalt shingles all qualify when installed over the right underlayment. Any valley the design keeps gets a metal liner over a mineral-surfaced cap sheet, and the open ends of a tile roof are sealed with bird stops so embers cannot drift under the tiles. Ridge and gable vents carry an ember and flame listing, or the roof is built unvented and has none.
Water away from the footing
Each downspout ends where water can spread without soaking the soil under the unit. On a flat lot a splash block and a graded swale may do it. Where the lot slopes, a solid pipe can carry the water to a dry well or a rock-lined outlet downhill of the building. The ground around the slab falls away from the walls, and the strip right beside them stays gravel or paving with no mulch. The city building department reviews the drainage with the rest of the drawings before anything is dug.
ADU Construction in Agoura Hills: common questions
Yes for a parcel inside one of the mapped zones on the state hazard map, and parts of Agoura Hills are mapped that way. The roof, siding, vents, windows and attached decking then follow the state wildfire standards. We check your address against the map first, and we can build the same shell on a lot outside it at your request.
Permit-ready drawings for one qualifying single-story unit. For Agoura Hills, the site plan shows where each downspout discharges and how the ground falls away from the slab, which the city reads alongside the roof covering's Class A listing. A bigger or two-story unit is quoted separately.
With both sets of drawings approved by the city, the two buildings can share one excavation stage, one round of utility trenches and one roofing order. Matching the unit's covering to the new house roof keeps the parcel consistent. We can complete the unit first, so it serves as your home on the lot while the main house is rebuilt.
