    Additions & Remodels in Pasadena, Los Angeles County

    We Build in Pasadena. We Know Pasadena.

    We know Pasadena block by block. From Bungalow Heaven, Madison Heights, San Rafael Hills, Hastings Ranch, Linda Vista, and everywhere in between, we've worked on homes across Los Angeles County for over 44+ years. Pasadena's historic districts protect some of the finest Craftsman architecture in America. Remodeling here is equal parts modernization and preservation, and design review is part of the job.

    Permitting in Pasadena has its own personality, and it directly affects your additions & remodels project. City of Pasadena Planning & Community Development / Building. Pasadena has extensive historic preservation: designated landmark districts (Bungalow Heaven, Madison Heights and others) require design review, and the city protects its historic Craftsman and Greene & Greene architectural legacy closely. Pasadena is one of the most preservation-driven cities in the region. Remodeling a home in a landmark district means design review and sensitivity to original architecture, especially the city's famous Craftsman bungalows. We modernize systems, kitchens, and baths while protecting the historic exterior character that gives Pasadena its value. Post-Eaton-Fire rebuild demand also spans western and northern Pasadena near the Altadena line. Our ICC-certified team handles every layer of the approval process so your additions & remodels moves forward without surprises.

    When you hire us for your additions & remodels in Pasadena, you're getting a contractor who understands the difference between a Craftsman or Greene & Greene bungalow home and a tract build. We spec materials and methods that fit the home and the neighborhood, not a one-size-fits-all approach.

    Why Homeowners in Pasadena Choose Us

    One Team. One Process. Zero Chaos.

    1. Design-Build Under One Roof

    2. Clear Timelines, Honored Commitments

    Written agreements include start and completion expectations. We set realistic schedules and we stick to them, because your time matters.

    Our team includes trade specialists in framing, foundation, roofing, plumbing, electrical, and finish carpentry. Every element of your addition handled by someone who does it every day.

    4. Quality You Can See and Feel

    We don't cut corners. Randy has trained tradespeople and written on what good construction looks like, and that standard is built into every addition we take on in Pasadena.
