Why Mason Remodeling Is San Marino’s Preferred General Contractor Company

A wide opening with a new beam where the kitchen wall was removed

San Marino homeowners tend to ask harder questions than most, and honestly, that’s exactly how it should be. This is a city where design review, lot coverage rules, and preservation overlays can change a project’s cost and timeline before the first hammer swings. We’ve scoped San Marino Home Remodeling work in the neighborhoods around Lacy Park, along Huntington Drive, and through the streets south of California Boulevard, so we know what San Marino’s building department expects before we submit a permit packet.

Our reputation in San Marino is built on two things: the written price we hand you before demolition starts, and the Threshold Standard we apply to every technician who arrives at your home. Background-checked, identity-verified, in a clean marked uniform, with a photo ID badge shown at the door. You’ll know the name and face of every person on your property before they arrive. No surprises on either count.

When you call (803) 680-2547, a live person answers. Not a call tree. Not a voicemail loop. A person who can talk through your project, your timeline, and your questions about San Marino permitting in real time, any hour of any day.

Licensed General Contractor in San Marino

A Licensed General Contractor in San Marino handles the full scope of a residential project: pulling permits, scheduling trade work, coordinating inspections, and holding everyone accountable to the written plan, the written price, and the completion date. For San Marino homeowners, this matters more than in most cities because the permitting and design review process here adds steps that an unlicensed or out-of-town contractor will miss or wave off. We don’t wave anything off. We build the review timeline into your schedule.

Permit and design review coordination

San Marino’s Residential Design Guidelines require city design review before permits issue for many exterior changes and additions. That’s not a formality. If your project touches a roofline, a facade, or lot coverage, we file the pre-application and manage the review queue for you. We track the plan-check schedule, the inspection sign-offs, and the correction cycles so your project doesn’t stall waiting on paperwork.

Scoping and pricing before demolition

We never start with a verbal number and hope it holds. Every San Marino project gets a written scope of work with itemized allowances for cabinetry, counters, fixtures, and finishes. That’s how a $14,000 to $45,000 kitchen remodel in San Marino stays within the range you approved, instead of growing by surprise change orders when you pick a Cambria island or a Kohler fixture.

Residential General Contractor in San Marino

A garage converted into a guest room and home office

A Residential General Contractor in San Marino manages the projects that make a house function better for the people living in it: kitchens, bathrooms, additions, ADUs, garage conversions, and whole-home remodels. We work exclusively on residential properties here, and we treat every job as if your family is living in the house while the work happens, because in most San Marino homes, they are. Dust control, clean job sites, locked tool storage, and a respectful crew are not add-ons. They’re standard.

Additions and ADU construction

Home additions in San Marino run from $45,000 to $130,000, and ADU construction ranges from $90,000 to $220,000. The spread is real because San Marino enforces a strict 45% maximum lot coverage, and properties in the Hillside and Historic Preservation overlays, like parts of the Old Mill and Lacy Estates districts, carry additional review requirements. We calculate coverage math before you spend a dollar on drawings, so you know what’s buildable on your lot before you commit.

Kitchen and bath remodeling

A full kitchen remodel in San Marino typically falls between $14,000 and $45,000, and a bathroom remodel between $9,000 and $28,000. The range depends on whether walls move, whether load-bearing structure is involved, and which material allowances you select. We write every allowance into the scope so the price you approve is the price you pay.

Trusted Brands We Service in San Marino

When we spec materials for San Marino projects, we work with specification-grade partners, not big-box clearance stock. That means KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, and Kohler and Moen fixtures. For smaller jobs and utility work, we keep proven products on hand, including Sakrete concrete mixes for driveway and hardscape pours and Cover for pre-engineered ADU elements where they fit a lot’s constraints. Working with Dvele on high-performance enclosure packages is an option for San Marino homeowners who want a tighter building envelope. You get vetted, professional-grade products priced in your written scope before work starts.

Common General Contractor Problems We See in San Marino Homes

  • Skipping design review until the permit packet is already in. San Marino’s design review pre-application step catches people off guard. A homeowner or a less experienced contractor files for an addition or exterior change, then discovers the project triggers design guidelines after the packet is submitted. That adds weeks of rework and resubmission. We file the pre-application first. Always.
  • Flat quotes without itemized allowances. A number without a breakdown is not a bid. If cabinetry, counters, and fixtures are not itemized, a Cambria or Silestone upgrade becomes a disputed change order instead of a planned line item. The dispute is avoidable. We itemize every allowance.
  • Underestimating San Marino’s plan-check queue. Contractors who assume a 4 to 6 week permit turnaround get burned here. San Marino’s plan-check and inspection scheduling runs on its own clock, and assuming a quick approval pushes the draw schedule and completion date out. We build the real queue into the calendar from day one.
  • Hidden structural conditions in older homes. San Marino has a deep stock of 1960s and earlier ranch houses, and load-bearing walls, subfloor rot, and outdated framing are common findings once demolition starts. We plan for the likely conditions in the scope, not as a surprise when the wall comes down.

One field note, because it’s the clearest picture of how we work: we scoped a 1960s ranch house kitchen in San Marino’s Lacy Park neighborhood not long ago. The homeowner wanted KraftMaid cabinets, a Cambria quartz island, and a Kohler sink, but the existing load-bearing wall between the kitchen and dining room had to stay. We pulled the permit, passed rough-in and framing inspection sign-offs, set a draw schedule, and delivered the finished kitchen inside the $14,000 to $45,000 kitchen remodel range, with a short punch list closed out 10 days after final inspection. That’s the process, start to finish, every time.
