ADU Construction in Calabasas
Calabasas ADUs placed around the panel, gas meter and sewer lateral of an older house, with ember-resistant shells and utility routes drawn for review.
The electrical panel on a Calabasas house can decide where an ADU belongs. A feeder from that panel to the unit runs in a trench, and every extra foot of trench adds digging, conduit and wire. We read the panel's rating, find the gas meter and trace the sewer lateral, then place the unit where those three lines stay short and clear of the older house's foundation, porch and original plantings.
Utility routes on a fire hazard parcel
Fire hazard mapping covers some Calabasas parcels, and on those the unit's shell follows the ember rules: Class A roof, mesh-screened vents, noncombustible cladding and tempered glass. Utility work has its own fire angle. Gas lines run underground to a shutoff at the unit, and an all-electric unit avoids a second gas run entirely. An underground electrical feed is used wherever practical, so no overhead drop crosses the yard. The city's building department reviews the utility plan alongside the structure, so each route is drawn with its depth and material.
Protecting the older house during the tie-in
Connecting to an older house can reach inside it. A panel upgrade may move the meter, a new sewer tee may sit under a porch, and a gas line may need a larger meter. We plan those cuts so the fewest original surfaces are touched. Plaster opened at the panel is patched to match, wood trim is removed with care and reinstalled, and any knob-and-tube or galvanized lines found along the way are listed in the scope with the choice to replace them while the walls are open.

ADU Construction in Calabasas: common questions
Each line is checked for room to grow. The panel gets a load calculation with the unit included, water pressure is tested where the unit's kitchen will be, and the sewer lateral is filmed end to end. A gas meter too small for both buildings can be upsized, or the unit can be built all-electric.
In many cases, yes, and its spot near the driveway can keep utility runs short. We inspect the slab, footings and framing, and check that the shell can be brought up to the fire rules if the lot is mapped. Where the garage cannot carry a finished dwelling, a new unit on that footprint works better.
We pick out what defines the house and carry it over: roof pitch, eave depth, the shape and grouping of windows, siding exposure and trim width. Each is built at the unit's smaller size. Where fire rules call for a different material, it is detailed to look like the original from across the yard.
