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
The Los Angeles-based architectural firm founded in 2010 describes itself as having a "bold and irreverent vision." Its projects include urban infill ground-up offices to single-family homes, adaptive re-use of derelict commercial buildings and renovations of historic landmarks.
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 company has been approved for two different one-story, one- or two-bedroom units, one at 532 square feet with an estimated cost of $200,000 and another at 784 square feet with an estimated cost of $300,000. 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.

How Replify Found Its Niche and an Acquirer
🔦 Spotlight
Hello LA,
This week’s startup story began three years ago with an AI assistant built for almost any small business. It ended, or perhaps graduated, with an acquisition by one of the fitness industry’s largest technology providers.
ABC Fitness has acquired Replify, an AI platform that manages customer communication for gyms and wellness businesses across phone, text, email and chat. Its virtual agents can answer questions, qualify leads, schedule tours and classes, follow up on missed calls and run outbound campaigns. Financial terms were not disclosed.
Before Replify found its footing in fitness, it was HeyLibby, a general-purpose AI assistant founded in 2023 by former Zillow colleagues Spencer Rascoff, Tony Small and Anna Rodriguez. The company was incubated inside Rascoff’s 75 & Sunny Labs and initially set out to help small businesses turn incoming messages into qualified leads.
That broad vision gave HeyLibby a large potential customer base, from real estate agents and contractors to hairstylists and event planners. But as the team searched for product-market fit, one industry’s problem stood out. Gym and wellness employees were often too busy helping customers in person to answer every call, text or email, leaving prospective members waiting and potential revenue on the table.
That insight reshaped the company. HeyLibby narrowed its focus to fitness and wellness, raised a $4.5M seed round in 2025 and later rebranded as Replify. It went on to work with brands including Gold’s Gym and UFC Gym, proving that its AI agents could do more than answer routine questions. According to the company, customers have captured up to 10 times more leads and shortened sales cycles from roughly 30 days to as little as three to five days.
ABC Fitness became a natural next step. The company provides software to more than 30,000 fitness businesses serving over 40 million members worldwide. By adding Replify to its platform, ABC can offer gyms an always-available AI front desk while bringing Replify’s technology to a much larger global customer base.
Replify’s journey offers a useful lesson amid the rush to build AI products for everyone. The company began with a broad promise, identified a customer with a specific and expensive problem, and built deeply around that need. Gym owners did not need another flashy chatbot. They needed someone to answer the phone when the front desk could not.
Sometimes the smartest AI strategy is simply picking up the call.

From Uber to Atoms: Travis Kalanick’s $1.7 Billion Return
🔦 Spotlight
Hello LA,
Nine years after his turbulent exit from Uber, Travis Kalanick is back with a new company, an enormous war chest and, apparently, some unfinished business.
Los Angeles-based Atoms announced this week that it has secured a $1.7 billion equity investment led by Andreessen Horowitz, with a16z cofounder Ben Horowitz joining its board. Bain Capital, Fifth Wall, Uber and several other investors participated, while a roster of major banks, including Goldman Sachs, JPMorgan and Bank of America, are listed as debt partners.
Yes, Uber itself is now backing the comeback of its famously ousted cofounder. Silicon Valley may preach disruption, but it has always appreciated a good redemption arc.
Atoms is the culmination of the company Kalanick has spent the past eight years building largely out of public view. Formerly known as City Storage Systems, the parent company behind CloudKitchens, it is now bringing its businesses together under one ambitious umbrella: Atoms Food, Atoms Mining and Atoms Transport.
The premise is that AI’s next major frontier will not be confined to screens, chatbots or software. Atoms wants to build what Kalanick calls a “computer for the physical world,” using software, sensors, robotics and AI to automate how physical goods are produced, stored and moved.
That means tackling decidedly unglamorous but enormous industries such as mining, construction, food production and heavy transportation. Rather than betting on humanoid robots that can theoretically do everything, Atoms is focused on specialized machines designed to perform specific, economically useful jobs.
In other words, the robot does not need a face. It needs a business model.
For a16z, the investment is as much a bet on Kalanick as it is on industrial AI. In an essay bluntly titled “Travis Is Back,” Horowitz argues that Kalanick possesses the rare mix of technical range, endurance and sheer force of will required to drag old-line industries into a new technological era. The firm’s broader thesis is that robotics will eventually handle much of the repetitive work involved in making, moving and storing physical goods, creating a market potentially as consequential as computing itself.
There is also some history being settled. Kalanick, Horowitz and Marc Andreessen nearly partnered during Uber’s early days but never completed the deal. In a new conversation about Atoms, Kalanick and Horowitz revisit that missed opportunity and the long road that brought them back together. Sixteen years later, the check is considerably larger.
The scale of the investment is remarkable, but so is its location. Atoms is headquartered in Los Angeles, giving the city a front-row seat to one of tech’s boldest industrial AI bets. It also reinforces something increasingly evident across LA’s startup ecosystem: the next era of AI will not only be written in code. It will be built in kitchens, warehouses, mines, vehicles and factories.
Whether Atoms becomes the operating system for the physical world or simply proves that even $1.7 billion cannot make atoms behave like bits remains to be seen. But Kalanick is taking another enormous swing, and this time, Los Angeles is where the comeback story begins.
