ADU Site Evaluation and Preparation
We start by analyzing the physical characteristics of your property in San Marino's San Rafael Hills terrain. This includes professional soil stability assessments, grading analysis, drainage evaluation, and inspection of existing structures like garages or sheds. Our team identifies the best location for the ADU to maximize space while complying with local setback and height restrictions.

Our licensed professionals and experienced team help anticipate common obstacles with city departments in this municipality with an annual operating budget of $25.8 million.
We track permit status and respond promptly to requests for additional information. Once permits are approved, we assist with scheduling inspections to maintain compliance throughout construction.

We also ensure construction plans comply with California's building codes, including fire safety and energy efficiency standards crucial for the area's dry climate and wildfire risk.

Specialized Garage Conversion Services
Transforming a garage into a functional living space involves careful planning, precise structural work, and updated utilities. Our services focus on ensuring compliance with local building codes and creating comfortable, efficient new areas tailored to your needs and property in Alhambra's established neighborhoods.
Garage-to-Living Space Transformations
We specialize in converting both attached and detached garages into usable living spaces, including bedrooms, home offices, guest suites, in-law units, or rental ADUs. This process begins with detailed architectural drawings to visualize the new layout and meet permit requirements while considering Alhambra's population density of 10,887 people per square mile.
Key steps include garage door removal and replacement with framed walls using premium lumber and professional insulation, window and door installation for natural light and ventilation to take advantage of the area's abundant sunshine, and concrete slab leveling when needed using high-strength leveling compounds.
Structural Assessment and Modifications
A thorough structural assessment is critical before beginning any garage conversion, particularly important given California's seismic considerations. We examine garage foundations, framing, and load-bearing elements to determine necessary reinforcements or modifications ensuring safety and longevity using licensed structural engineers and professional assessment protocols.
If the garage slab requires leveling or repair, we handle concrete work to provide a stable base using reinforced concrete and professional-grade curing techniques. In some cases, we modify exterior walls to improve insulation and energy performance suitable for the region's Mediterranean climate. Fire-rated separation requirements between the garage and the main house are also evaluated and addressed according to local codes using approved fire-resistant materials and proper installation methods.
Finishes and Utility Upgrades
We complete garage conversions with professional drywall installation and finishing, followed by flooring installation suited to the function of the new room using premium hardwood, luxury vinyl, or ceramic tile materials. Electrical systems are rewired to provide updated lighting and outlets, including energy-efficient fixtures that work well in Alhambra's climate with minimal seasonal lighting variation.
Plumbing work is done when converting to spaces requiring water access, such as in-law suites or guest bathrooms, using copper or PEX piping systems and professional-grade fixtures. We install or extend HVAC systems, often using mini-split units to ensure proper heating and cooling in the area's dry, temperate climate. Our team manages permit applications and supports obtaining certificates of occupancy to ensure compliance and peace of mind.
