Why Choose Ridgeline Western Construction for Duplex Construction in Oak Hills
A duplex project in Oak Hills starts with layout and zoning checks to confirm placement and code rules for side-by-side or stacked units. Ridgeline Western Construction reviews the design and works with engineering for wall assemblies, utility splits, and fire-rated separations that meet local interpretation in San Bernardino. / Site prep, foundation, and in-house framing lead off, using engineered lumber, sheathing, and hardware rated for multi-family demands. Plumbing, electrical, HVAC, and other trades are coordinated under us, so rough-ins are done in sync and there are no gaps between phases. This reduces common hand-off delays in dual-unit builds. / The job finishes with separate utility meters, final punch, and a full sign-off for each unit. You receive a completed duplex in Oak Hills with permits closed, inspection records, and documentation of every fire, sound, and utility separation required by San Bernardino.

Coordinated Schedule for All Trades
Every subcontractor—from concrete to roof, plumbing to finish—is scheduled and watched directly by us in Oak Hills. Trade hand-offs are locked in by phase, not left open. This keeps the project moving rather than waiting on another company’s timing.

Permitting and Final Inspection Managed
We follow Oak Hills's permit process, handle all drawings and submittals, and handle city inspection scheduling. At finish, you get a permit record and occupancy documentation meeting San Bernardino requirements, ready for new tenants or sale.

On-Site Framing for Two Units

What Our Clients Say about us..
"I connected with Steven Moreno at Ridgeline Western Construction about a year ago when I was scoping out a project. Steven’s knowledge blew me away from framing, additions, new construction, materials, etc. He broke everything down like it was nothing & in a way that I actually could understand. The company is based out of Fontana and covers a huge range from San Bernardino and Riverside all the way through Los Angeles and Orange County. So if you’re in that area and need a general contractor that you can rely on then I would highly recommend Ridgeline Western Construction to get the job done right."
