Guest House & Casita Construction in San Bernardino, CA

Guest house and casita construction in San Bernardino covers everything from a backyard build to a garage conversion or second-story unit. Ridgeline Western Construction manages design input, permitting, and the entire construction process—from the initial site work and slab to the last fixture installation. You work directly with the contractor through every phase, with framing self-performed and all other trades managed under one contract for a job that runs as a whole, not scattered parts.

Why Choose Ridgeline Western Construction for Guest House & Casita Construction in San Bernardino

Building a guest house or casita in San Bernardino means following local ADU rules for setbacks, height, and occupancy, while still aiming for efficient use of property space. Ridgeline Western Construction starts by verifying these details, helping coordinate the required design and engineering steps. If you already have plans, we move straight to permit submittal and city plan check. Every detail of square footage, size, and separation from the main house is reviewed early, so the build fits the letter of San Bernardino codes.

The construction phase uses a single contract and one managed schedule. We self-perform the framing with dimensional and engineered lumber, install structural sheathing, handle exterior waterproofing, and coordinate all city inspections in order. Licensed subcontractors handle each of the specialties: electrical, plumbing, HVAC, and finish trades. Roofing is managed through our dedicated roofing partner. The approach is designed for inspection sign-off at every stage, so you are not left waiting on missed steps or trade gaps.

When finish work wraps, we schedule the final inspection and handle any punch items that arise. The completed guest house or casita is fully permitted, with all inspection records provided. You walk the space with Steven Moreno, who clarifies any code compliance or maintenance issues. The job is closed out directly with the city, so no permits or final sign-offs are left outstanding.

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."
