Stearnlee ADU
Torrance homeowners are sitting on some of the best ADU opportunities in the South Bay. With its abundance of mid-century ranch homes, generous lot sizes, and relatively homeowner-friendly permitting process, Torrance is an ideal city to add an Accessory Dwelling Unit — whether your goal is rental income, multigenerational living, or simply increasing your property's long-term value.
At Sennikoff Architects, we design custom ADUs for Torrance properties that feel intentional and architecturally cohesive, not like an afterthought tacked onto the back of your lot.
ADU Opportunities in Torrance
The mid-century homes that define much of Torrance — particularly in neighborhoods like Hollywood Riviera, Southwood, and Old Torrance — tend to have detached garages and rear yards that are well-suited for ADU development.
Depending on your property, your options may include:
-
Detached ADUs — A standalone structure in your rear yard, ideal for maximizing privacy for both the primary home and the ADU
-
Garage Conversions — Converting an existing detached garage into a fully permitted living space, often the most cost-effective path
-
Attached ADUs — An addition to your existing home with its own entrance, kitchen, and bathroom
-
Junior ADUs (JADUs) — A smaller unit created within your home's existing footprint, with minimal construction required
Navigating Torrance's ADU Permitting Process
The City of Torrance has adopted California's state ADU laws, which have significantly loosened restrictions on where and how ADUs can be built.
That said, Torrance still has its own local standards around setbacks, lot coverage, and design compatibility that need to be addressed in your permit application. Projects in certain neighborhoods may also be subject to additional design review.
Working with an experienced architect from the start ensures your project is designed to meet Torrance's specific requirements before you ever set foot in the permit office — saving time and avoiding costly redesigns mid-process.
Why Sennikoff Architects
Steven Sennikoff is a California licensed architect with nearly 35 years of residential design experience across the South Bay and greater Los Angeles area. We've designed ADUs in a range of configurations and budgets — detached backyard units, above-garage studios, and garage conversions — and we bring that hands-on experience to every Torrance project we take on.
We handle every phase in-house: schematic design, construction documents, permit coordination with the City of Torrance, and construction support through completion. You work directly with Steven, not a project manager or junior staff member.
What to Expect When You Work With Us
We start every project with a property assessment and goal-setting conversation. From there we develop design options, produce a full permit-ready drawing set, and manage the city approval process on your behalf. Our goal is to make the process as clear and low-stress as possible for you.
