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:

Revel’s pitch is simple: rockets, advanced energy, robotics, and defense systems have evolved fast, but the tooling that tests and commands them is still stuck in the past. The company says its platform can cut test stand setup time from 14 days to about 8 hours, and that teams go from testing every other day to multiple tests per day. One customer, Impulse Space, reportedly runs 80+ instances of RevelTest, and Revel claims every pilot it has run has converted into a paying customer.
What makes this more than “just another big round” is where Revel is aiming next: expanding from test stands into industrial control across critical infrastructure, including nuclear facilities, power stations, refineries, water treatment, data centers, and biomedical manufacturing. Their platform includes live telemetry and safe command execution, and even a purpose built language, RevelCode, designed for deterministic, debuggable control in high consequence environments. In other words, if LA is becoming a capital of hard tech, Revel is trying to become the control room software those companies standardize on.Keep scrolling for the latest LA venture rounds, fund news and acquisitions.
