Torrance Remodeling & Design-Build Contractor
Design-Build Remodeling in Torrance
Optima Design & Build is a licensed general contractor serving Torrance homeowners in Old Torrance, Walteria, Southwood, Seaside, the Hollywood Riviera and across the city. We handle the full project in one place: design and 3D renderings, a detailed proposal, city permits, and construction through the final walkthrough.
Torrance has many solid 1950s and 1960s ranch homes that are ready for a modern kitchen, updated baths or extra space. We recently completed the kitchen remodel shown below in Torrance and are building a second-story ADU here now, so we know how the city's process works.

What to Know Before You Remodel in Torrance
Torrance has its own permit process and plenty of homes that are perfect for adding space. We plan for both from day one.
City permits
Torrance has its own Building and Safety and Planning divisions. We prepare complete plans and handle the submittal, corrections and inspections.
Garage conversions and ADUs
Converting a garage or building a detached ADU is one of the best ways to add space or rental income. We check parking, setbacks and utilities early and handle everything through final inspection.
Older homes, hidden conditions
Homes from the 1950s to 1970s often have outdated wiring, galvanized plumbing, and lead or asbestos in older materials. We test where needed and price it upfront.
Coastal neighborhoods
Homes near the coast in Seaside and the Hollywood Riviera deal with salt air and moisture. We choose materials, hardware and ventilation that hold up.

Verified Google ReviewTorrance Remodeling Questions
Do you handle permits in Torrance?
Yes. We prepare the drawings and submit to the City of Torrance, and we manage the process through corrections and final inspection.
How long does a kitchen or bathroom remodel take?
Construction for most bathrooms takes about 3 to 8 weeks and most kitchens about 5 to 10 weeks, depending on scope. Design and permits come before that. We give you a project timeline with the proposal.
Can I build an ADU in Torrance?
In most cases, yes. State law allows ADUs and JADUs on most single-family lots, and garage conversions are a common option here. Setbacks, parking and utilities affect what fits, so we check feasibility on your property first.
How much will my remodel cost?
It depends on size, layout changes and finishes. After the on-site consultation and 3D design, we give you a ballpark range, and then a detailed proposal so you know the cost before work begins.
