Looking to Build a Granny Flat in Your Backyard? Meet the Firms and Designs Pre-Approved in LA
Adding a backyard home in Los Angeles is now nearly as easy as buying a barbecue.
Homeowners who for years have wanted to build a granny flat in their backyard, but dreaded the red tape, can now choose from 20 pre-designed homes that the city has already approved for use.
The shift, made official last week, will speed up a weeks-long process and bring more badly needed units to an overpriced market. It also has the potential to elevate the 14 startups and firms building the next generation of homes.
The designs for the stand-alone residences range from a 200-square-foot studio to a 1,200-square foot, two-story, two-bedroom unit. And many of the homes are filled with design flourishes, reflecting the diverse architecture of the city, from a house in the silhouette of a flower to one with a spiral outdoor staircase leading to the roof.
It's no surprise. The program was spearheaded by Christopher Hawthorne, a former architecture critic at the Los Angeles Times and now the city's chief design officer.
The firms are primarily local and startup architecture and design firms, while others are well-known with a history of building granny flats, also know as accessory dwelling units, or ADUs.
The standard plans avoid the Los Angeles Department of Building and Safety's typical four-to six-week review process and can allow approvals to be completed in as quickly as one day.
Some aspects of the plans can be modified to fit a homeowner's preferences. Eight other designs are pending approval.
Mayor Eric Garcetti believes by adding more such units, the city can diversify its housing supply and tackle the housing crisis. Recent state legislation made it easier to build the small homes on the lot of single-family residences. Since then, ADUs have made up nearly a quarter of Los Angeles' newly permitted housing units.
Because construction costs are relatively low for the granny flats – the pre-approved homes start at $144,000 and can go beyond $300,000 – the housing is generally more affordable. The median home price in L.A. County in January was $690,000.
Here's a quick look at the designs approved so far:
Abodu
Abodu
Abodu, based in Redwood City in the Bay Area, exclusively designs backyard homes. In 2019, it worked with the city of San Jose on a program similar to the one Los Angeles is undertaking.
In October, it closed a seed funding round of $3.5 million led by Initialized Capital.
It has been approved for a one-story 340-square-foot studio, a one-story one-bedroom at 500 square feet, and a one-story, 610-square-foot two-bedroom.
The pricing for the studio is $189,900, while the one-bedroom costs $199,900 and the two-bedroom is $259,900.

Fung + Blatt Architects
Fung + Blatt Architects is a Los Angeles-based firm founded in 1990.
The city has approved its 795-square-foot, one-story, one-bedroom unit with a roof deck. It estimates the construction cost to be $240,000 to $300,000, excluding landscape, site work and the solar array. Homeowners can also expect other additional costs.

Jennifer Bonner/MALL
Massachusetts-based Jennifer Bonner/MALL designed a "Lean-to ADU" project, reinterpreting the stucco box and exaggerated false front, both Los Angeles architectural mainstays.
The design has been approved for a 525-square-foot one-story, one-bedroom unit with a 125-square-foot roof deck.
sekou cooke STUDIO
New York-based sekou cooke STUDIO is the sole Black-owned architectural firm on the project.
"The twisted forms of this ADU recalls the spin and scratch of a DJ's records" from the early 90s, the firm said.
Its design, still pending approval, is for a 1,200-square-foot, two bedroom and two bathroom can be adapted to a smaller one-bedroom unit or to include an additional half bath.
SO-IL
New York-based SO-IL was founded in 2008. It has completed projects in Leon, Seoul, Lisbon and Brooklyn.
Its one-story, one-bedroom 693-square-foot unit is pending approval. It is estimated the construction cost will be between $200,000 and $250,000.
WELCOME PROJECTS
Los Angeles-based Welcome Projects has worked on projects ranging from buildings, houses and interiors to handbags, games and toys.
Its ADU is nicknamed The Breadbox "for its curved topped walls and slight resemblance to that vintage counter accessory."
It has been approved for a one-story, one-bedroom 560-square-foot unit.

Founded in 2013, the company has already proven its technology can work via pilot programs in Sweden, Germany and Italy—as well as its homeland of Israel, where it’s a publicly traded company on the Tel Aviv Stock Exchange. But on Tuesday, Electreon announced a partnership with Michigan public authorities, as well as private stakeholders like Ford Motor Company, to install a one-mile-long stretch of electrified road in Detroit—the first time such a system would be used in public roads in the U.S. The system is expected to be operational by next year.
Electreon, which opened its U.S. headquarters in Los Angeles last month, is initially targeting fleet vehicles like taxis, buses and drayage trucks for its technology, but plans to eventually expand into the consumer EV market as well. Electric road systems would be especially attractive to fleet vehicles for a number of reasons, the most obvious being that they stop frequently. Time spent idling, especially in predictable locations, means it’s easier to know where to install electrified roads and make them cost-effective.
Stefan Tongur, Electreon’s L.A.-based vice president of business development, says the company’s induction charging technology will probably charge slower than the traditional plug-in station model. But if the pavement under every bus station was electrified, he told dot.LA, a small amount of charge would be added to the vehicle at every stop—meaning the bus would need to take fewer, if any, breaks to recharge its battery.

It’s easy to imagine similar use cases at ports, rail yards or airport taxi lanes, all of which could spell significant savings for companies that lose time and money when their electric fleet vehicles are plugged in and recharging. Many of these areas also fall under the purview of the private sector, which would make uptake and implementation easier, according to Tongur. He said Electreon is already eyeing a move into such spaces.
Electreon aims to have its wireless charging technology installed on public roads around the U.S. within “a couple of years,” Tongur added. While Detroit will host the pilot program, Los Angeles and New York will be the next targets.
“L.A. is obvious, right? It’s the Mecca of EVs,” he said. “You have air quality issues here; you have the port of L.A. and Long Beach; you have so much traffic. Moving to electrification is, I would say, a must.”
The goal of installing wireless charging for moving vehicles is “very courageous,” said Mehrdad Kazerani, a professor of electrical and computer engineering at the University of Waterloo in Ontario, Canada. Kazerani noted that researchers at the university had developed a similar concept for the sprawling Trans-Canada Highway. “Of course, we did not pursue this idea, but it seems Electreon has made good progress along this line,” he said.
Kazerani added that wireless charging technology may also allow the EVs of the future to use considerably smaller batteries, which would make the cars lighter, more energy-efficient and less expensive. Smaller batteries would also mean less mining for battery materials and less waste when a battery reaches the end of its life.
“This is kind of an invitation to the U.S. market: to policymakers, state agencies, fleet owners and original equipment manufacturers,” Tongur said. “This is an opportunity to do things together—join us on this path and journey.”
