New Construction in Calabasas
Calabasas houses with irrigation, planting beds and soil lines planned as part of the water plan, plus wildfire details and an ADU worked in.
Landscape water is water too. A sprinkler head aimed at a stucco wall, a planting bed that buries the weep screed or a lawn that tilts toward the foundation can do more damage than a rainstorm. On a new Calabasas house the irrigation plan and the planting layout are drawn alongside the drainage sheet so the two never fight each other.
Soil lines and weep screeds
The bottom edge of a stucco wall needs a few inches of clearance above bare soil and a smaller gap above paving, so moisture can escape through the weep screed. Planting beds are graded to hold that clearance. Irrigation heads are set to throw water away from the walls, and drip lines serve beds that sit near the house. A bed filled with mulch up to the stucco blocks the screed, so mulch stops short of the wall and leaves the metal edge visible.
Fire rules, plants and the city
Fire hazard maps include some Calabasas addresses, so plantings near the house are chosen and spaced with defensible space in mind, and the irrigation plan shows how that zone is kept watered. City plan check covers the grading sheet, and an ADU on the lot shares the same drainage and irrigation layout. Foundation drains, downspouts and yard inlets are shown on the grading sheet so the inspector can follow water from the roof to the street, and nothing is left to guesswork.
New Construction in Calabasas: common questions
The drainage sheet, irrigation layout and defensible-space plan can serve both a house and a unit, so plants and water lines are set once, if the lot qualifies. Setbacks and lot coverage decide where it can sit.
Water movement across the lot gets studied beside the survey and soils testing. Design and engineering come next, then city plan check. Any house already standing needs a demolition permit and utility shutoffs ahead of excavation, and footings wait for the permit.
Calabasas plans get read for structure, energy use and green measures, then for zoning on height and yards. A grading and drainage sheet is part of the set, mapped fire hazard parcels add wildfire rules, and ADU law sets additional state and city requirements.
