Your Albany, CA Addition & ADU Expert
3G Builders & Renovation
Living in Albany offers charm, walkability, and established neighborhoods, but many homes were built decades ago and weren’t designed for modern lifestyles. Whether you’re near Solano Avenue, tucked between Marin Avenue and San Pablo Avenue, or living close to Albany Hill, your home may need additional space to keep up with evolving needs. Thoughtfully designed home additions and accessory dwelling units can provide that flexibility without sacrificing character.
Expanding a home in Albany requires careful planning due to smaller lot sizes, setback regulations, and established neighborhood patterns. From early feasibility studies to permit coordination and final construction, 3G Builders & Renovation manages each step with precision and transparency.
We design and build custom additions and ADUs throughout Albany, CA that enhance livability, respect architectural context, and increase long-term property value.

Custom Home Additions in Albany
3G Builders & Renovation
Expanding your Albany residence means maximizing every square foot intelligently. With compact lots common throughout neighborhoods near Marin Elementary or Memorial Park, additions must be efficient, structurally sound, and architecturally cohesive.
Whether you’re extending a kitchen, building a primary suite expansion, or enlarging living space for a growing household, we evaluate lot constraints, foundation capacity, and structural integration before construction begins. Our design-build team ensures the addition feels proportionate and naturally integrated with the original home.
Each project is built to complement Albany’s established residential character while improving day-to-day function.
Accessory Dwelling Units (ADUs) in Albany, CA
3G Builders & Renovation
With California’s evolving ADU legislation, Albany homeowners are increasingly adding detached or attached units to create rental income, guest housing, or private workspace. However, tight lot configurations and city-specific zoning requirements demand careful planning.
We design ADUs that optimize small footprints while maintaining privacy and code compliance. Whether converting garage space near San Pablo Avenue or adding a backyard cottage near Washington Avenue, we focus on efficient layouts, natural lighting strategies, insulation performance, and separate access where feasible.
Our Albany ADUs are built to meet local regulations while delivering practical, comfortable secondary living space.
Second Story Additions & Vertical Expansions
3G Builders & Renovation
For many Albany properties, expanding upward offers the best opportunity to gain square footage without sacrificing yard space. Second story additions require detailed engineering assessments, particularly in older homes common throughout the area.
We analyze foundation strength, framing capacity, and seismic reinforcement needs before designing upper-level expansions. Staircase placement, exterior transitions, and roofline continuity are carefully coordinated so the second story feels original to the home.
The finished vertical expansion enhances livability while preserving valuable outdoor space.
Bump-Outs & Focused Room Expansions
3G Builders & Renovation
Strategic expansions can dramatically improve functionality without requiring a full structural overhaul. Kitchen bump-outs, bathroom enlargements, and small rear extensions are popular solutions among Albany homeowners looking for meaningful upgrades within limited lot dimensions.
We design these expansions with structural efficiency, exterior continuity, and interior flow in mind. Each project is carefully integrated to ensure the new space enhances usability while respecting neighborhood density and property lines.
Garage Conversions & Secondary Unit Transformations
3G Builders & Renovation
Many Albany homes include detached garages or underutilized structures that can be repurposed into legal ADUs. Converting these spaces requires insulation upgrades, slab moisture mitigation, window additions, fire separation measures, and utility planning.
We coordinate permitting with local authorities and ensure all life-safety and energy requirements are met. The finished conversion becomes a fully functional living space that adds flexibility and long-term value to your Albany property.
