Desert-modern precision. Coastal-grade materials. White-glove management.
Specialty Builders was built around a simple frustration with the industry standard: too many contractors treat a client's largest financial investment like a checklist. We built our company to be the opposite. Every custom home, ADU, and renovation we take on is run with the same discipline as a commercial project — documented scope, published timelines, and a single point of contact who answers the phone.
Our crews live across the Inland Empire and know how Southern California's soil, seismic requirements, and climate swings actually affect a build — not just what a spec sheet says. That local knowledge, paired with high-end material sourcing usually reserved for coastal estates, is what separates a Specialty Builders project from a standard remodel job.
From ground-up custom homes to income-generating ADUs to full renovations of existing structures, each project type gets its own dedicated process, crew coordination, and finish standard.
Ground-up dream homes built with the precision your vision deserves.
We take your lot, your lifestyle, and your design concept and turn them into a fully realized custom home — from foundation to finish. Every structural decision, material selection, and finish detail is reviewed with you at each phase. We coordinate architects, engineers, and subcontractors so you don't have to juggle a dozen conversations. The result is a home that reflects exactly who you are and holds its value for decades.
Accessory dwelling units that add value, income, and flexibility.
Accessory dwelling units are one of Southern California's smartest investments — and we build them to the same exacting standard as our full custom homes. From detached casitas to garage conversions and attached suites, we handle permitting, design coordination, and construction start to finish. Our ADU clients typically see measurable equity gains and rental income potential within the first year of completion.
Transform an existing structure into something extraordinary.
A great renovation requires more than new finishes — it demands a builder who can read the bones of a structure and know what to keep, what to remove, and what to reimagine. We've renovated everything from mid-century ranch homes in Rancho Cucamonga to Mediterranean estates in Claremont. Our team manages demolition, structural modifications, MEP rough-in, and all finishes under one roof, eliminating the coordination chaos that sinks most renovation projects.
Every project moves through the same four stages, in order, with nothing skipped and nothing left to guesswork. Scroll or drag through the reel below.
We start with a no-obligation conversation — in person or on-site — to understand your project scope, design goals, and timeline. There's no hard sell, just an honest discussion about what's possible.
Within a week, you receive a line-item estimate, a preliminary schedule, and a clear scope of work document. No vague lump sums — you'll know exactly what you're approving.
Once contracted, you're assigned a single point-of-contact project manager who oversees every phase, attends every inspection, and is reachable by phone or text throughout construction.
Before we call a project complete, we walk through every inch together. Any open punch-list items are resolved before final payment — your satisfaction is the closeout condition.

All workmanship is backed by a 2-year guarantee — if it's not right, we return and make it right at no cost.
We publish a milestone timeline before breaking ground and hold ourselves to it — no surprise delays, no excuses.
Your detailed estimate is your contract price. We don't add hidden line items after the job starts.

"Specialty Builders turned our dated 1980s ranch house into a completely reimagined modern home. They were upfront about costs from day one, kept us informed at every phase, and the finished product blew us away. We've already referred two neighbors."
"We hired them to build a detached ADU on our Upland property. From permits to final inspection, the whole process took four months — faster than we expected and exactly on budget. The quality looks and feels like a brand-new home."
"The team at Specialty Builders handled our commercial office renovation in Ontario with real professionalism. We needed to stay partially operational during construction and they staged the work perfectly. Clean, on schedule, and outstanding craftsmanship."

Specialty Builders was founded in the Inland Empire and has watched this region grow from a bedroom community into one of California's most dynamic construction markets. We're not a firm that parachutes in from elsewhere — our crews live in the cities we build in, our kids go to school here, and our future is tied directly to the health of this community.
We sponsor local youth sports leagues in the Ontario and Rancho Cucamonga area, contribute materials and labor to Habitat for Humanity builds in San Bernardino County, and maintain relationships with regional trade schools to mentor the next generation of skilled tradespeople. When you hire Specialty Builders, the economic benefit stays local — and that matters to us as much as it should matter to you.
Specialty Builders serves three counties across Southern California — San Bernardino, Riverside, and Los Angeles — with crews based locally in the Inland Empire. Wherever your project sits on the map below, you get the same project management, the same craftsmanship standard, and the same response time promise.
