The job, in three frames
How the job runs with J.O. Construction, in the order it happens.
1
Step 1: Design to the budget
Plans, finishes and windows chosen with the price in front of you, so nothing gets drawn twice.
2
Step 2: Engineering and the permit set
The engineer sizes the structure, and we put the permit set together and send it to the city.
3
Step 3: Build what was drawn
The crew that priced the plans builds them, so questions get answered on site, not by email.
What design-build covers
Floor plans, structural engineering, the city permit set, and the build itself. You deal with one contact instead of chasing an architect, an engineer and a contractor separately.
Why it helps on Chino projects
When the builder prices the design as it is drawn, you find out early if a window wall or a steel beam breaks the budget. On one Riverside home we held meetings between the designer, the engineer and the window supplier before framing so the angled glass went in right the first time.
Design-build near Chino: recent work
We have run design-build ADUs in Fontana and Rancho Cucamonga with interior designers, and custom homes in Riverside with outside architects.
Is this the right call for your project?
Call us for this when
- You have a lot or a rough idea, but no plans yet
- You want to know early if a window wall or a beam breaks the budget
- You would rather have one contact than three
Pick something else when
- Your architect already finished the plans: we build from them as your custom home builder
- You are weighing whether to build custom at all: start with the custom home builder overview
- You only need drawings with no build: that is an architect's job, and we will tell you so
After the final inspection: keeping it in shape
- 1
Keep the final plan set
The as-built drawings show where every line runs. The next repair or addition starts there.
- 2
Hold on to the finish list
Paint colors, tile names and cabinet finishes. Touch-ups match when you know exactly what went on.
- 3
Walk the house after a season
Doors and drawers can shift as new framing settles. Note what sticks and get it adjusted once.

Design-Build questions from Chino owners
Is design-build cheaper than hiring an architect and a contractor separately?
Design-build is not always cheaper, but it cuts redesign. Because the builder prices the plans while they are drawn, fewer drawings get thrown out for being over budget, and plan check goes in sooner. See how the phases line up on our custom home build timeline.
Who pulls the permits on a design-build project in Chino?
We do. On a design-build project in Chino we prepare the permit set with the designer and engineer and submit it to the city building department.
One team from sketch to keys.
