ADU Construction in Westlake Village
Westlake Village ADUs laid out for a private entrance and their own yard, built to ember rules where mapped and styled after the older main house.
Can the unit have its own entrance, out of sight of the main house's windows? We settle that standing at the gates and side yards of a Westlake Village lot, sketching a separate path to the new door. The unit's windows are turned toward its own patch of yard, and a fence line or planting can screen the rest. Where fire hazard mapping covers the parcel, that layout also keeps a clear way to the back.
Placement, height and the city's standards
Plan review in Westlake Village applies state ADU law along with the city's own limits for height and setbacks. Within those, we test where the unit fits best: near a rear corner for privacy, or closer to the driveway for short utility runs. Trees worth keeping and the line of the sewer lateral narrow the choices. If the yard slopes, the footing design and drainage are worked out together with the placement. Each option is sketched to scale so the tradeoffs are clear before drawings begin.
Ember rules and the older house
On a fire-mapped parcel the unit's exterior follows the state wildland rules: a Class A roof, enclosed eaves, vents with ember screens, noncombustible or ignition-resistant walls, and tempered glazing. We choose those products to look like the materials of the older main house, so a fiber cement board echoes its wood siding and a metal gutter follows its profile. The house's systems are checked as well. A small panel, galvanized pipe or a clay lateral is tested before the unit is sized, and any upgrade is planned to leave original finishes in place.

ADU Construction in Westlake Village: common questions
After testing, and with upgrades where the numbers call for them. We run a load calculation on the panel with the unit included, film the sewer lateral to its connection and check the water supply for a second kitchen and bath. A fuse panel or failing galvanized line in the house is dealt with before the unit relies on it.
Yes, when the structure is sound, and a conversion holds the garage's current place on the lot under state rules. We check the slab, look for footings and inspect the framing for rot. If the parcel is fire-mapped, the shell gets the ember upgrades as part of the change, so siding, vents and roofing may be renewed.
Work from the house down in scale. Roof slope and overhang set the outline, then window shape and spacing, siding type and trim width fill it in. Color comes from samples of the house. Where fire rules require a different material, it is picked in a profile close to the original, so the buildings still look related.
