Our Comprehensive ADU Construction Services

We offer complete accessory dwelling unit solutions tailored to different property types and homeowner goals. Our versatile services address various construction scenarios, from ground-up builds to conversion projects that transform underutilized spaces into functional living areas.

New Detached ADU Construction

Building a detached accessory dwelling unit provides maximum privacy and flexibility for Lemon Heights homeowners with adequate yard space. We construct freestanding ADUs ranging from compact 400-square-foot studios to spacious 1,200-square-foot two-bedroom units, all designed with modern amenities and energy-efficient features. Our construction process includes site preparation, foundation installation, complete framing, roofing, exterior siding, and full interior finishing with contemporary fixtures and appliances. Detached units offer the advantage of separate entrances, independent utilities, and complete separation from the main residence.

Garage Conversion and Remodeling

Transforming an existing garage into a livable space represents one of the most cost-effective ADU options for Lemon Heights properties. We convert attached or detached garages into comfortable accessory dwelling units while addressing structural modifications, insulation upgrades, HVAC installation, and creating functional floor plans with full kitchens and bathrooms. Our garage conversion expertise includes proper foundation reinforcement, window installation for natural light, and exterior improvements that maintain cohesive curb appeal. This approach maximizes existing structures while adding significant property value.



ADU Gas Line Installation

Safe and compliant gas line installation is essential for ADUs with gas appliances, heating systems, or cooking equipment. Our licensed technicians design and install complete gas line systems that meet California's strict safety codes and provide reliable service to your accessory dwelling unit. We coordinate with utility providers, handle all inspections, and ensure proper sizing for your specific appliance requirements, including tankless water heaters, furnaces, ranges, and dryers. Professional ADU gas line installation prevents future safety hazards while ensuring your ADU has access to efficient, cost-effective energy sources for daily living.

Our Construction Excellence from Foundation to Finish

Quality construction requires skilled tradespeople, attention to detail, and proactive problem-solving when unexpected conditions arise. We maintain direct oversight of all work, ensuring every phase meets our exacting standards before moving to the next stage.

Our Foundation and Structural Systems

We evaluate soil conditions and design foundation systems that provide stable, long-lasting support appropriate for your site's characteristics and local seismic requirements. Our framing crews use premium lumber and engineered components, following plans precisely while adapting to field conditions with proper engineering approval when necessary. We install proper moisture barriers, flashing, and weatherproofing that protect your investment from water intrusion and structural damage. Regular inspections at critical stages catch any issues early, preventing problems that become expensive to correct after walls close up.

Our Mechanical and Electrical Systems

Licensed plumbers install water supply lines, drain systems, and gas connections that meet code requirements and provide reliable service for decades. Our electricians design panel capacity, circuit layouts, and outlet placement that support modern electrical demands while maintaining safety margins. HVAC contractors size heating and cooling equipment appropriately, install ductwork efficiently, and ensure proper ventilation prevents moisture and air quality issues. We coordinate all mechanical trades carefully, avoiding conflicts and ensuring clean, professional installations that pass inspection without complications. For projects involving roofing adjustments and extensions for garage conversions, we ensure proper integration of new roof structures with existing systems, maintaining weatherproof integrity while creating the ceiling heights and slopes necessary for comfortable living spaces.

Our Interior Finishes and Final Details

Our finish carpenters install trim, doors, and cabinetry with precision, creating clean lines and tight joints that demonstrate quality craftsmanship throughout. We help you select flooring, paint colors, fixtures, and hardware that match your vision while staying within budget parameters. Tile work in bathrooms and kitchens receives careful attention, with proper waterproofing and layout that looks professionally installed. Final cleaning, punch list completion, and walkthrough ensure you receive a move-in ready unit that exceeds expectations.
