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.
Amunátegui Valdés Architects
Led by Cristobal Amunátegui and Alejandro Valdés, the firm was founded in 2011 and has offices in Los Angeles and Santiago, Chile. Amunátegui is an assistant professor at the Department of Architecture and Urban Design at UCLA.
The firm designs work in various scales and mediums, including buildings, furniture and exhibitions.
Its one-story, two-bedroom with a covered roof deck 934-square-foot unit is pending approval from the city.
Connect Homes
Connect Homes has a 100,000-square foot factory in San Bernardino and an architecture studio in Downtown L.A.
It specializes in glass and steel homes and has completed 80 homes in California. Its designs have an aesthetic of mid-century modern California residential architecture.
It has two one-bedroom models pre-approved by the city, one is 460 square feet, which costs $144,500 with a total average project cost of $205,000. The other is 640 square feet, which costs $195,200 with a total project cost of $280,000.
Design, Bitches

Its pre-approved design, named "Midnight Room," is a guest house/ studio. Its bedroom can be left open for a loft feel or enclosed as a separate room. The design is a one-story, one-bedroom at 454 square feet.
Escher GuneWardena Architecture
Founded in Los Angeles in 1996, Escher GuneWardena Architecture has received international recognition and has collaborated with contemporary artists, worked on historical preservation projects and more.

The firm noted the costs depend on site conditions and do not include soft costs. Those could add 10% to 12% to the total construction costs.
First Office
First Office is an architecture firm based in Downtown Los Angeles. Its approved ADUs will be built using prefabricated structural insulated panels, which allow for expedited construction schedules and high environmental ratings.
The interior finishes include concrete floors, stainless steel counters and an occasional element of conduit.

- A one-story one-bedroom, 534 to 794 square feet

Taalman Architecture/ IT House Inc.
The design team behind "IT House" is Los Angeles-based studio Taalman Architecture. Over the past 15 years, IT House has built more than 20 homes throughout California and the U.S.

The city has approved two of LA Más' designs: a one-story, one-bedroom, 528 square feet unit and a one-story, two-bedroom, 768 square feet unit. The firm has another design for a one-story studio pending approval. That design would be the first 3D-printed ADU design in the city's program.

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.

This LA Startup Wants to Make It Rain and Just Raised $25M to Do It

Hello LA!
While most tech headlines are busy chasing AI chatbots and flying taxis, one startup in El Segundo is aiming a little higher. Literally.
Rainmaker just secured$25 million in Series A funding to expand its cloud-seeding drone technology. The round was led by Lowercarbon Capital, with participation from Starship Ventures, 1517 Fund, Long Journey Ventures, Naval Ravikant, and others.
Their idea is simple but urgent. Instead of relying on old-school aircraft to spray rain-making particles across the sky, Rainmaker uses AI-powered drones that find and seed clouds with pinpoint accuracy. It is faster, more affordable, and could reshape how regions fight back against droughts.
California's ongoing water struggles have made it clear that simply "saving" water is not enough. Cities and entire economies need new tools to create it. Rainmaker plans to use the funding to grow its fleet, invest in atmospheric science, and expand commercial partnerships with utilities and governments searching for solutions.
Bigger picture, Rainmaker is part of a growing shift in LA's tech ecosystem. While software remains dominant, more investors and founders are quietly betting on "hard tech" that addresses real-world problems like water, energy, and infrastructure.
It is not just about apps anymore. It is about survival tech.
With the skies getting hotter and the reservoirs getting lower, the next great tech export out of LA might not be entertainment or social media. It could be rain.
Stay tuned…

Hello Los Angeles, and happy Friday!
Memorial Day Weekend is finally here, and it seems even PCH got the memo, just in time for those coastal drives to kick off summer, traffic jams included. Speaking of navigation, El Segundo based startup CX2 has charted its own impressive course this week, securing $31 million in a Series A round led by Point72 Ventures, with participation from Andreessen Horowitz, 8VC, and Pax Ventures, to boost its mission in electronic warfare.
Electronic warfare (EW), for those of us who aren't regulars at the Pentagon, involves the tactical use of electromagnetic energy to control the spectrum, essentially jamming or confusing enemy communications and radar systems. CX2 was founded by a diverse and experienced group: Nathan Mintz, who brings deep expertise in defense technology from previous ventures such as Epirus and Spartan; Mark Trefgarne, a software entrepreneur known for a successful acquisition by Meta; Lee Thompson, an expert RF engineer previously with SpaceX; and Porter Smith, whose practical insights stem from his background as a U.S. Army helicopter pilot and subsequent experience as an investor.
The new funds will help CX2 scale its team and accelerate the development of advanced tools, including autonomous drones and specialized signals-intelligence systems. These innovations promise precision interference without collateral disruptions, addressing critical defense capability gaps identified by industry experts.
With tensions escalating globally, there's big demand for next-gen defense solutions, and CX2’s technology positions them as a major player in shaping future electronic battlespaces.
Dive deeper into the details and check out this week's roundup of LA’s venture deals and acquisitions below.
