Custom Home Builders in Riverside, CA
Designed around your life. Built on time. Priced before we break ground.
Designed around your life. Built on time. Priced before we break ground.
A quick phone call to align on what you're building, what you're working with (lot, budget, timeline), and whether we're the right fit. No pressure.
We visit your property. Setbacks, slope, soils, access, utilities, view considerations, neighborhood character — all reviewed before design begins. If your lot has constraints that affect cost, we tell you up front.
We lead a design team (architect, structural engineer, energy compliance) and lock down floor plans, elevations, finishes, and specifications. By the end of this phase, you have permit-ready plans, a fixed-scope contract, and a realistic build schedule. Design and pre-construction fees typically run $3,000–$10,000.
We submit to the City of Riverside (or Rancho Cucamonga, Temecula, etc.) and manage all comments, revisions, and inspections through final approval. You don't sit on hold with planning departments.
Most custom homes take 10–14 months from groundbreak. You get weekly on-site walkthroughs, daily updates through Houzz Pro, one point of contact, and a written 5-year workmanship warranty at handover. Most builds typically run $800–$1,250 per square foot, scoped to your finishes and complexity.
Riverside lots aren’t uniform. Canyon Crest hillsides need different foundations than Wood Streets infill. Mission Grove HOAs have different setback rules than Orangecrest. Rancho Cucamonga’s permitting workflow is different from Temecula’s. We’ve built across all of them, which means the surprises that delay other builders — soil reports that come back unexpected, hillside engineering, view-protection rules, school-zone setbacks — get handled before they become surprises.
After 18 years, we know which city planners reply to email and which need a phone call. We know which inspectors care about which details. That’s not glamorous, but it’s why your project finishes when we say it will.
Open-plan kitchens for hosts. Quiet wings for parents. Single-level for buyers planning to age in place. Multigenerational layouts with private entries. We design from how you'll use the house, not from a stock plan with your name on it.
Premium materials, engineered framing, energy-efficient envelopes, solar-ready roofs. Every selection is documented in your specs so you know exactly what's behind your walls — and what to ask the next contractor about in 20 years.
Schedules don't slip because of weather or material delays — they slip because of disorganization. We pre-order long-lead items, coordinate trades on a weekly look-ahead, and update the schedule when anything changes. Most builds finish within a week of the original target date.

We’ve had the pleasure of seeing JJ Builders’ work firsthand on an ADU project, and it was truly impressive, top-notch craftsmanship, clean finishes, smart design, and attention to every detail that makes the build stand out. What really sets them apart, though, is Josh (the owner). He’s such a kind, respectful, and overall great person to work with. From our interactions, it’s clear he genuinely cares about his clients, listens carefully, and approaches everything with honesty and professionalism. If you need a reliable contractor for an ADU, remodel, addition, or custom home, go with JJ Builders. Josh and the team are the real deal, highly recommend!Posted on Google Ryan DodsonTrustindex verifies that the original source of the review is Google. Top notch service and creativity. Josh Phillips has an unbelievable talent for building. Thank you very much for the creative ideas and help with our ADU build. I will forever use you and your company for all of my building needs.Posted on Google Matthew BaltazarTrustindex verifies that the original source of the review is Google. HUGE SHOUTOUT to Joshua at J.J Builders. They ensure your project is done quickly, professionally, and efficiently. Biggest thing I appreciate is the constant communication. For me, communication is key. It was refreshing to always have an update to any changes, delays, start/end times, etc and not left in the dark wondering what the hell is going on (like some other contractors will do). They will always be my number one recommendation and first call for any other future construction work.Posted on Google Gabriela DevineTrustindex verifies that the original source of the review is Google. I proudly recommend Josh and JJ.Builders! We needed some work done on our personal property and not only did he make sure everything was handled great from start to finish but he and his team far exceeded our expectations. Since working with him, I now recommend the company to not only all my real estate clients, but anyone in need of any work, including additions, builds, and conversions, whether it be residential or commercial. Highly recommend!Posted on Google David FontesTrustindex verifies that the original source of the review is Google. JJ builders were great they helped us build an A.D.U.
