ADU & Garage Conversion Services in Los Angeles

Transforming an existing property with an accessory dwelling unit has become one of the most effective strategies for Southern California homeowners seeking multi-generational living quarters or consistent rental yield. However, designing and building a self-contained residence within an existing parcel requires structural precision and rigorous municipal coordination. While many marketing firms promote themselves as accessory dwelling unit builders only to broker the work out to disconnected sub-crews, ProMen delivers accountable, builder-managed execution. Backed by 14+ years of construction experience and headquartered in Burbank, our company operates under California CSLB License #1116606 (Class B), maintaining $2,000,000 in general liability insurance and comprehensive surety bonding. When homeowners invest in custom adu construction, ProMen provides single-point management from zoning feasibility through certificate of occupancy.

Navigating permitting for adu los angeles projects requires exhaustive coordination with local municipal building authorities. Whether developing detached backyard cottages or converting existing structures in Burbank, Glendale, Pasadena, or the City of Los Angeles, our team manages plan checks and permit submittals directly with LADBS and local building departments. On the structural side, standalone auxiliary homes require engineered soil compaction, reinforced perimeter footings, and structural shear wall hold-downs in strict compliance with applicable California structural and seismic requirements. By managing staged municipal inspections proactively, our project superintendents help reduce scheduling delays and keep construction milestones on schedule.

Financial transparency and clear milestone accounting protect homeowner equity throughout construction. A secondary residence represents a substantial financial asset, generating substantial passive income or long-term family value. ProMen conducts comprehensive site evaluations and detailed project consultations upfront, delivering transparent, itemized estimates that account for foundation engineering, framing packages, utility trenching, and finish installations. To guarantee financial protection, all progress payments are supported by California-compliant conditional and unconditional lien releases aligned with California payment schedules and approved project milestones.

Converting an attached or detached garage into a legal residential dwelling requires addressing severe structural and environmental deficits typical of utilitarian spaces. Operating as an experienced garage conversion contractor, ProMen specializes in the structural modernization required to make concrete garages habitable. Existing garage slabs frequently slope toward vehicle doors and lack moisture protection. Our team installs heavy-duty vapor retarders and self-leveling cementitious underlayments, while sistering ceiling joists and framing 2×6 exterior walls to accommodate high-R-value acoustic and thermal insulation. Under our in-house California C-10 Electrical license, we install dedicated subpanels, 240V circuits for induction cooktops and water heating, and smart LED fixtures. Through our C-20 HVAC license, we install energy-efficient ductless mini-split climate systems. For sewer connections and kitchen/bath plumbing lines, we manage close coordination with appropriately licensed trade partners.

Achieving optimal climate efficiency and modern comfort is essential under California’s stringent building standards. ProMen applies California Title 24 energy efficiency requirements strictly to energy-related scope, including high-performance continuous exterior wall insulation, Title 24-compliant fenestration with low U-factor ratings, Cool Roof underlayment, and whole-house mechanical ventilation. From compact custom kitchenettes with quartz countertops to space-saving pocket doors and spa-like bathrooms, ProMen balances space optimization with durable craftsmanship. For property owners looking for a dependable local general contractor to transform underutilized square footage into a pristine living space, ProMen delivers enduring building excellence across Los Angeles County.
