ADU Site Evaluation and Feasibility Assessment

Before design begins, we conduct comprehensive site evaluations to analyze zoning laws, property setbacks, and environmental constraints. This helps us determine what is feasible on your lot and avoid costly revisions later in this city incorporated in 1903.

Our feasibility assessment includes soil analysis, slope considerations, and existing infrastructure reviews. Understanding these factors early ensures your ADU complies with local regulations and fits well within the property's landscape in Alhambra's western San Gabriel Valley location. Our licensed professionals provide detailed reports that support permit applications.

3D Renderings and Project Visualization

To help you envision the finished ADU, we provide detailed 3D renderings and project visualizations. These allow you to see realistic representations of materials, layouts, and exterior finishes before construction starts in Alhambra's year-round mild climate.

Visualizing your ADU through these tools makes it easier to suggest changes, refine design elements, and ensure that the final build matches your expectations. We prioritize clarity and accuracy in every rendering, using advanced software to showcase quality materials and finishes.

ADU Construction Services and Methods

Detached and Attached ADU Construction

We specialize in both detached and attached ADU construction in Alhambra, CA. Detached ADUs are separate structures, often built in the backyard or side yard, providing privacy and flexibility. Attached ADUs share a wall with the main home and typically involve adding space through second-story additions or ground-level extensions.

Our detached ADU construction services include site evaluation, foundation work, and full-frame building using high-quality lumber and steel components. Attached ADU builds focus on seamless integration with your existing home, utilizing matching materials and architectural elements.

Custom Garage Conversion ADUs

Garage conversion ADUs are an efficient way to add living space without expanding your building footprint. We transform underutilized garages into fully compliant living units by upgrading insulation, plumbing, electrical systems, and interiors in Alhambra's Mediterranean climate that requires minimal heating.

Our service includes feasibility studies and permits, ensuring the converted garage meets all building codes. These conversions utilize moisture-resistant materials and energy-efficient systems, serving as Junior ADUs while maximizing value and versatility.

Basement and Above-Garage ADU Solutions

For homeowners with suitable basements or garages, we provide conversion services that turn these spaces into livable ADUs. Basement ADU conversions often require waterproofing, egress windows, and specialized HVAC solutions designed for Alhambra's dry climate with average annual rainfall of 16 inches.

Above-garage ADUs add functional space without consuming yard area. This method involves constructing a second-story unit using quality framing materials and weather-resistant finishes, maintaining the architectural character of Alhambra's diverse housing styles.

Prefab, Modular, and Container ADUs

We also install prefab and modular ADUs, offering faster build times with factory-constructed components. These units arrive onsite ready for assembly, reducing disruption and labor costs in Alhambra's established neighborhoods while maintaining construction quality standards.

Shipping container ADU builds provide a durable, eco-friendly alternative. Our container home ADU contractor services adapt containers into comfortable living spaces with proper insulation, energy-efficient windows, and integrated utilities tailored for the region's climate conditions.

Structural Engineering and Systems Integration

Our approach begins with precise structural engineering, ensuring all components work together seamlessly for durability and safety. We focus on strong base elements and properly integrated mechanical, electrical, and safety systems tailored for ADUs in Alhambra's seismically active California environment.

Foundation, Grading, and Framing

We start by assessing soil conditions to determine the appropriate foundation type, whether slab-on-grade or raised pier foundation. Proper grading ensures water drainage away from the structure, preventing future damage in Alhambra's occasional winter rains.

Our structural engineering incorporates seismic retrofitting to comply with California's strict building codes. Using steel frame options and engineered lumber improves stability and fire resistance, essential for this region's earthquake considerations while maintaining cost-effectiveness.

Plumbing and Electrical System Installation

We install plumbing systems using copper and PEX piping, focusing on integrating sewer and gas lines efficiently within existing municipal systems. Pipe materials and layouts comply with local codes to ensure safe water flow and waste management in Alhambra's established infrastructure.

Electrical work includes dedicated circuits for kitchen appliances, lighting, and HVAC systems. We use GFCI outlets and LED fixtures, prioritizing safety and utility cost reduction for homeowners in this city where 17% of residents are under 18 and 18% are over 65.
