Like real love, the practice of architecture doesn’t always run efficiently. But Ben Warwas dealt with a substantial drawback when designing a yard house, or ADU, in L.A.’s Mar Vista community: the power lines overhanging the rear lot line. Given that the architectural designer’s customers were committed to converting their garage into a two-story ADU, positioning it in distance to the L.A. Department of Water & Power’s height restrictions, Warwas now needed to find a way to work around the lines.
Though overhead power lines present an obstacle to designers and designers around the U.S., they’re specifically bothersome in L.A., where more ADUs are being built than anyplace else. Considering that grounding power lines can be prohibitively pricey, and require a collaborated effort in between energy companies and neighbors, designers and home builders of ADUs across the Southern California city are instead developing novel workarounds for lines flowing through yard airspace.
Often it requires creative positioning of an unit or changing the massing in some way– something designer Melissa Shin calls “the electrical slide.” She experienced her own energy issue on an ADU presently under building and construction on L.A.’s West Side, a standalone, two-story unit designed to make the most of California’s lowered back and side backyard obstacle requirements for brand-new separated ADUs.
Shin designed a 715-square-foot ADU in Westwood that responds architecturally to the overhead power lines. The roofing system is contoured by the lines, and a stair frames them. The blue fascia color was picked to match the sky, creating an illusion of higher distance in between the lines and the roof.Since there was a power pole at the back of the residential or commercial property, Shin, the principal at Shin Shin, had to obtain an advancement permit with the DWP’s Real Estate Services department. After 4 months she received notice the application had actually been declined.” Our very first submission was for an ADU set as far back as we might go, however they returned and informed us we either needed to move it or decrease the height,” she says.”At that point, the building was currently approved through plan check, so to return and slash off five feet, you’re basically starting over.”
Rather, she just moved it. Since the pole rested on the home itself, Shin ended up with a nine foot, six inch total obstacle. “So although the minimum allowed ADU problem is four feet, which is substantially less than any other type of building, we could not take advantage of it.”
Architect Hunter Knight, founder and principal of Weather condition Projects, keeps in mind a far easier procedure before the present ADU structure boom. “Four or 5 years ago, a DWP clearance for building near electrical lines wasn’t needed. But with ADUs being so close to lot lines, individuals would start building, and they ‘d call DWP and state they needed a meter spot [where the energy company verifies where you can install your new or updated electrical service panel] And DWP may come out and state, ‘Your building’s too near the power lines. It’s a security issue.’ And you ‘d state, ‘Whoops, we didn’t understand.’ And they ‘d say, ‘You were supposed to contact us.’ And we ‘d state, ‘We were? We went through the entire Building & Security prepare check– we thought we were excellent.’ So they made it a clearance in Structure & Security.”
Though there are only 2 methods to bring power from utility infrastructure to an ADU– overhead or underground– property owners connecting power to an ADU by means of an electrical service drop from the pole still have to underground the line in between the unit and the main house. But Knight cautions that if the overhead connection for the drop is too far from the transformer, the solution is costly, in regards to both cash and time. “And if the overhead line is routed over a habitable location, you have to spend for DWP to engineer that, and you pay for the underground routing from the pole,” he says. “That’s where things get actually expensive. That almost got set off for an ADU I designed in Cypress Park, however in the end, the DWP chose they didn’t require to underground the line after all.”
