General Construction
From the foundation up, The J Hammer Inc is a licensed CSLB General Building (Class B) contractor handling ground-up construction, structural work and full project management across Los Angeles and Ventura Counties.
One licensed contractor for the whole build
A General Building (B) license is the broadest residential license California issues — it covers any project that involves two or more trades, which is nearly every real construction job. That is exactly why homeowners hire The J Hammer as their general contractor: instead of coordinating a roofer, a framer, an electrician and three other trades yourself, one licensed team owns the schedule, the permits, the inspections and the result.
We manage new construction, structural remodels, garage and ADU builds, and large multi-trade projects from the first site walk to the final inspection sign-off. You get one point of contact, one written scope, and one crew accountable for the whole thing.
What we handle
- Ground-up structures — ADUs, garages, guest houses and additions, engineered and permitted.
- Structural work — foundations, framing, beams and load-bearing changes with engineer’s calcs.
- Full project management — permits, plan check, trade scheduling, and inspection coordination.
- Multi-trade remodels — projects that touch framing, electrical, plumbing, roofing and finish all at once.
Why the license matters in Los Angeles
California requires a licensed contractor for any project over $500 in combined labor and materials, and building or structural work almost always requires permits and inspections. Hiring a licensed B contractor protects you three ways: the work is pulled on permit and inspected, the contractor carries insurance, and the project is documented — which matters enormously when you sell. Our license (CSLB #1045849) is verifiable at cslb.ca.gov, and we carry $1M/$2M general liability.
How a project runs
Every build starts with a site walk and a conversation about scope, budget and timeline. We produce a written scope where each phase is spelled out, handle the drawings and permits, then run an organized, safe work site with daily cleanup. You are kept in the loop at every milestone, and payments track completed work in line with California law — never a large sum up front.
