LADU

LADU entered the Los Angeles ADU market in 2021 with an explicit mission: to strip away the confusion and delays that plague most homeowner projects in California's complex permitting landscape. Founder and CEO Babak Mortazavi brought fifteen years of real estate development experience to identify a gap: homeowners facing ADU decisions had no single source they could trust. The result was LADU, a full-service design-build operation now managing over 120 active projects at any moment across Southern California.

The company's scope is genuinely comprehensive. LADU handles site assessment and custom design, manages the full permitting process from filing through approval, arranges financing if the homeowner needs it (partnering with lenders offering HEA, HEI, and HELOC products), oversees construction from foundation to final inspection, and even tackles the legalization of unpermitted ADUs already on a property. This last service addresses a real problem in Los Angeles: existing accessory units built without permits, their owners now seeking to bring them into compliance. LADU's approach is to handle the retrofit design and the paperwork rather than demand a teardown.

Their design team spans multiple architects with complementary skills. Lucía Bassetti-Blum, the lead designer, studied architecture at Cornell and has over a decade in residential design, much of it in New York City before relocating to Los Angeles. This combination of Cornell training and East Coast experience brings a precision to space planning that differs from typical contractor-led design. The team also includes software engineering capability, a less common pairing that allows them to build their own project-tracking portal so homeowners can follow the build in real time.

The design options LADU presents fall into standard categories but with specific square footages and layouts. Their one-bedroom units typically run 675 square feet with a full kitchen, separate living area, and a bedroom with an ensuite bath. The two-bedroom option reaches 800 square feet, expanding the floor plan to accommodate a second sleeping space. For smaller properties or stricter zoning rules, they offer a garage conversion or junior ADU path, which sits at 400 square feet and works best for a single occupant or a guest suite. All designs incorporate what LADU calls their "zero headache" philosophy, meaning they design specifically to pass Pasadena's rules in Pasadena, Santa Monica's rules in Santa Monica, and so on, rather than starting with a generic floor plan and hoping it fits. The permitting landscape differs radically by jurisdiction. Los Angeles city has different setback rules than unincorporated areas. Santa Monica has different height limits than Malibu. Orange County municipalities add their own layers. This jurisdiction-specific design approach costs more upfront but pays for itself the first time a permit sails through.

The geographic reach is substantial. LADU serves 64 distinct neighborhoods across five counties: Los Angeles County (51 neighborhoods), Orange County (5), San Diego County (3), Riverside County (2), and San Bernardino County (2), plus one area in Ventura. This doesn't mean they have boots on the ground everywhere, but they maintain the permitting and zoning expertise for all of these areas. A homeowner in Eagle Rock or Westchester can work with the same team as someone in San Clemente. The largest concentration is naturally in Los Angeles County, where the company has the deepest relationships with city planning departments.

Financially, LADU doesn't publish a price list on their site. Instead, they offer a free initial site visit and assessment, after which they provide an estimate. This is common practice in custom construction, where a $50,000 difference between two properties can hinge on soil conditions, setbacks, or existing structure limitations. They emphasize transparent pricing and claim "no billing surprises," but the actual construction cost for your specific ADU will depend on your lot and your design. They do offer financing programs through partners, which broadens access for homeowners who can't pay in cash. For someone looking at a 675-square-foot one-bedroom, comparable builds in greater Los Angeles have historically ranged from around $200,000 to $300,000 total, but that's a reference point only and your specific project will depend on location, labor costs at the time, and site conditions.

The timelines LADU targets are four to six months from permit approval to completion, though the permitting phase itself can extend timelines. Some jurisdictions in Los Angeles County issue ADU permits in a month; others take three to four months. Santa Monica tends toward the longer end. The company reports a 94% on-time completion rate, meaning the vast majority of projects are completed within their targeted timeline. The stated 100% permit approval rate would mean no rejections or required resubmittals from planning departments. This is harder to independently verify but aligns with their design-to-jurisdiction approach, where the design team tailors plans specifically to each city's requirements.

The portfolio includes photo documentation of completed work. You'll see a two-bedroom 850-square-foot unit in one neighborhood, garage conversions in another, and various one-bedroom configurations across different Los Angeles areas. The specificity here matters: each project shows the actual lot size, the actual neighborhood, and the actual completed work. No stock photography or generic renderings padding the gallery. LADU's communication style leans professional and straightforward rather than marketing-heavy, which appeals to homeowners who want facts more than enthusiasm.

One of LADU's distinguishing choices is their willingness to handle unpermitted ADU legalization. California cities have created pathways for this, though each city's rules differ. If you have an ADU that was built without a permit (common in older Los Angeles), legalizing it involves retrofitting it to meet current code, documenting the retrofit with permits, and passing inspection. This is expensive and sometimes impossible if the structure is too far out of code. LADU will do the technical assessment and handle the process if it's viable, but they're upfront that some existing structures can't be salvaged. This honest boundary-drawing distinguishes them from competitors who might promise to legalize anything.

LADU's positioning directly addresses the pain points that have historically kept homeowners from building ADUs. The uncertainty around permitting, the fragmented advice, the difficulty of finding a contractor who understands both design and the permitting process, and the financing gap all fall away when you work with a firm that has managed over 120 active projects across multiple jurisdictions. The risk of a permitting rejection, which would delay your timeline considerably, shrinks when the design team already knows what your city will approve.

For Los Angeles and Orange County homeowners looking to add an ADU, LADU's combination of jurisdiction-specific design, transparent process, and financing support makes them a strong fit, particularly if you value the convenience of a single team handling everything from site visit to move-in.
