Los Angeles Garage Conversions — The Smart ADU Starting Point
A Los Angeles garage conversion is the fastest, most affordable path to a legal ADU — and Caspi Construction manages every step from LADBS permits through the finished, rentable unit.
For Los Angeles homeowners who want to add a legal, rentable ADU to their property without the cost and complexity of new construction, a garage conversion is the most practical starting point. The existing structure — slab, framing, roof — is already there, which eliminates the foundation work and structural build-out costs that make detached ADUs so expensive. A typical garage conversion in Silver Lake, Los Feliz, Palms, or the Valley runs $80K–$130K all-in, compared to $150K+ for a new detached build, and the LADBS Accessory Dwelling Unit Standard Plan Program allows pre-approved plan sets that can significantly reduce permit review time. Caspi Construction is a licensed garage conversion contractor in Los Angeles (CSLB #1091631) with a 4.9★ rating. We handle everything — structural assessment, insulation, MEP rough-in, drywall, flooring, cabinetry, tile, and all finish work — under a single design-build contract. All LADBS permits are managed as part of every project.
Our Los Angeles Garage Conversion Services
Structural Assessment & Reinforcement
Not every Los Angeles garage is equally suited for conversion — slab thickness, framing condition, roof structure, and setback compliance all affect feasibility. We conduct a thorough structural assessment before any design work begins, identify what reinforcement or modification is needed to meet LADBS habitability requirements, and provide a clear feasibility report. Most detached garages in Los Angeles's older neighborhoods are excellent candidates for conversion with minimal structural work required.
LADBS Permit Management & Standard Plan Program
The LADBS ADU Standard Plan Program offers pre-approved plan sets for common garage conversion configurations, which can dramatically reduce the plan check timeline — from several months to a few weeks in many cases. We assess whether your garage conversion qualifies for the Standard Plan pathway and recommend it when appropriate. For conversions that require custom plans, we prepare full architectural drawings and manage the standard LADBS review process from submission through all required inspections.
Full MEP Installation & Insulation
A garage becomes a habitable ADU through the addition of complete mechanical, electrical, and plumbing systems. We install a dedicated electrical sub-panel, a mini-split HVAC system for independent climate control, rough-in and trim-out plumbing for a full kitchen and bathroom, and insulation in all walls and the ceiling to meet Title 24 energy compliance requirements. This systems work is the backbone of a garage conversion ADU in Los Angeles — doing it right means a unit that's comfortable to live in, not just legally permitted.
Interior Finish Work — Kitchen, Bath & Living
We complete every Los Angeles garage conversion with quality finish work: MSI tile in the bathroom, Caesarstone or MSI quartz in the kitchen, semi-custom cabinetry, LVP flooring in the main living area, and Kohler fixtures throughout. The kitchen is designed to the footprint that the conversion allows — typically a galley or L-shape — with full-size appliances, a deep sink, and adequate counter prep space. The bathroom is designed for practicality: walk-in shower, floating vanity, and efficient storage.

Recent Garage Conversion Projects in Los Angeles
Project 1 — Silver Lake Detached Garage Conversion
A Silver Lake homeowner had a detached two-car garage in the rear of their lot — sound structure, original concrete slab, but used exclusively for storage. With Silver Lake rental market rates running at $2,200–$2,800 for a studio, the conversion economics were compelling. We assessed the structure, confirmed Standard Plan Program eligibility, submitted plans, and completed construction in fifteen weeks from permit approval: insulated walls and ceiling, mini-split HVAC, a full bathroom with MSI Calacatta Miraggio tile and a Kohler walk-in shower, a galley kitchen with Caesarstone White Attica quartz countertops, LVP flooring throughout, and new windows and an exterior door on the alley side. The unit has been rented continuously since certificate of occupancy.
Project 2 — Los Feliz Single-Car Garage Conversion
A Los Feliz homeowner had a single-car detached garage — a smaller footprint at 280 square feet that required creative design to meet LADBS minimum ADU habitability requirements. We designed a studio configuration that maximized every square foot: a Murphy bed wall with integrated storage above and beside, a kitchen alcove with under-counter appliances and MSI quartz, a bathroom with a 32x32 walk-in shower and wall-mounted floating vanity, and clerestory windows added to the rear wall for natural light without sacrificing privacy. The garage conversion in Los Angeles was completed in twelve weeks through LADBS, and the unit has been used as a short-term furnished rental.
Project 3 — San Fernando Valley Attached Garage Conversion
A homeowner in the eastern San Fernando Valley had an attached two-car garage adjacent to the main house — structurally sound, already on the home's electrical panel, and sharing a common wall with the laundry room that simplified plumbing access. We converted the 440-square-foot garage to a one-bedroom JADU — separating the bedroom from the living area with a partial partition wall, adding a kitchenette with a two-burner cooktop and under-counter refrigerator on Caesarstone quartz, building a full bathroom with MSI porcelain tile and a Kohler walk-in shower, and installing a new exterior door and window on the side of the garage. The ADU design build in Los Angeles was completed in ten weeks under LADBS JADU permit.

Common Questions From Homeowners
The LADBS ADU Standard Plan Program offers pre-approved architectural plan sets for common ADU configurations, including several garage conversion layouts. Using a pre-approved plan can reduce the LADBS plan check timeline from several months to a few weeks, significantly accelerating the start of construction. Caspi Construction assesses whether your garage conversion qualifies for the Standard Plan pathway and uses it when it applies.
Los Angeles garage conversion ADUs typically run $80K–$130K all-in, including structural assessment, LADBS permitting, all MEP systems, insulation, and finish work through a certificate of occupancy. Cost varies based on garage size, the extent of structural reinforcement required, and finish specification level. We provide a detailed estimate after the structural assessment and review.
A standard garage conversion ADU is a fully independent dwelling unit with its own entrance, kitchen, and bathroom — it can be rented to anyone. A Junior ADU (JADU) is a conversion of up to 500 square feet within or attached to the existing home — it requires the property owner to occupy either the primary residence or the JADU. Both require LADBS permits. We evaluate which designation applies to your garage and design accordingly.
Yes — attached garage conversions are eligible for the same LADBS ADU pathways as detached conversions. An attached garage conversion that shares a wall with the main house typically qualifies as a JADU rather than a standard ADU, which affects rental rules but not construction requirements. We assess your specific configuration during the feasibility review.
A Los Angeles garage conversion ADU using the LADBS Standard Plan Program typically moves from permit submission to construction start in six to ten weeks. Construction itself runs ten to sixteen weeks depending on the garage size and finish scope. Total timeline from initial consultation to certificate of occupancy is typically eighteen to twenty-six weeks.
