Built to last in Los Angeles.
A general contractor delivering custom residences and integrated energy systems. Twenty years in the LA market. CSLB #984586.
The firm.
Principle Building Group Inc. is a licensed Los Angeles general contractor — CSLB #984586 — delivering custom residential and light commercial construction under one contract across the LA basin.
Hundreds of residential and light-commercial projects across LA over twenty years. Custom homes. Whole-home remodels. ADUs. Roofing. Integrated solar-and-battery. Light commercial.
One firm. One contract per project. Full scope from pre-construction through close-out.
How PBG runs a project.
Pre-construction planning.
The full trade stack — structural, MEP, envelope, energy — coordinated on drawings before permit application. Coordination with structural, MEP, and geotechnical engineers where the site conditions require it. Sequencing settled on paper before mobilization.
In-house permit administration.
LADBS plan check, corrections, and inspections managed by our permit team. Coastal Commission, hillside pathway, ADU intake — experienced across every LA district.
Integrated envelope-plus-energy.
Roof, panel, mounting, battery, EV-ready electrical planned as one system. Title 24 and NEM 3.0 addressed at design phase.
Change management.
Budget and timeline changes surfaced before trades start work. Not accumulated to closeout.
Close-out.
Punch list, final inspection, warranty follow-through by the same project team that ran construction. One point of contact through the warranty period.
Envelope to energy stack. Under one contract.
Roof, panel, solar mounting, battery, EV-ready electrical — coordinated at design phase, executed as one integrated system on site.
Structural loads for the array planned at framing. Service panels sized for full electrification at rough-in. Title 24 and NEM 3.0 handled at drawing-table decisions.
Most general contractors defer the energy stack to specialty subcontractors after certificate of occupancy. PBG delivers envelope and energy under a single contract, a single project team, a single warranty conversation.
Team and capabilities.
An in-house team of project managers, superintendents, and field crews — with pre-construction, estimating, and permit administration under the same roof. Our project managers coordinate the trade stack. Our field staff has run projects through three LA code cycles, the recent Title 24 tightening, and the NEM 1.0-through-3.0 transition on residential solar.
PBG remains under original ownership. Project delivery approach and quality standards are set by the firm's leadership and applied consistently across every project.
