Most GCs stop at framing. We keep going — through the roof, into the solar array, and out to the battery. Twenty years across Los Angeles, one contract per project.
From new custom builds to solar-plus-battery retrofits, we run each job with the same crew discipline and the same license — CSLB #984586, in force twenty years.
Ground-up single-family builds across LA. Hillside, flat lot, coastal. Architect, engineer, permitting, construction under one contract.

Learn more →New roofs and re-roofs on residential and light commercial. Composition, tile, standing-seam metal, flat-roof membrane. Integrated with solar mounting where the roof and array get planned together.
Learn more →Grid-tied PV systems. Battery storage in usable kWh. NEM 3.0 interconnection strategy. Built with the envelope, not bolted on after.
Learn more →Tenant improvements and small ground-up commercial. Office, retail, mixed-use, medical. LADBS commercial pathway, delivered on schedule.
Learn more →Most contractors hand off the solar work. We don't.
When PBG builds a new home or a whole-home remodel, the roof, the electrical rough-in, and the solar-plus-battery design get planned together — not bolted on after certificate of occupancy. That means:
Twenty years in LA teaches you that the buildings that age well are the ones where the trades were sequenced right on paper. That's the work we do before the excavator arrives.
Principle Building Group is Ziv Mesika. The license on file is his. The projects were run by him. When you hire PBG, you hire an owner-operator who's spent twenty years learning what the LA building code doesn't tell you.
We're small on purpose. The person quoting your project is the person running your project is the person whose license is at stake. There's no dispatcher between you and the operator.
You cannot short-cut twenty years of running crews in Los Angeles. Not with software, not with subs, not with charm.
Every neighborhood in this city has a different set of jurisdictional quirks. Coastal Commission where the lot faces the water. Hillside grading where the slope crosses fifteen percent. LADBS residential plan check on a flat lot in Encino runs differently than the same set of drawings in Beverly Hills.
That's what twenty years buys you:a builder who's been priced-in through market cycles you haven't seen yet.
LADBS is our second office. Residential plan check, coastal, hillside, ADU pathway, commercial TI. You don't chase corrections — we do.
Ziv Mesika is the licensed principal on every project. Not a project manager three layers removed — the person whose license is on file. When you call PBG, you call the operator.
Change orders happen; scope creeps. We tell you when it's happening and what it costs before the trade starts the work. No surprise invoices at closeout.
Hillside grading, soils reports, coastal jurisdiction, Title 24 revisions, NEM 3.0 tariffs — we've watched the code cycle and the market cycle three times through. Experience shows up in the details you didn't know to ask about.
Real project case studies — with photography, client permission, and full scope detail — go live here as current PBG projects wrap and photography completes. Below is representative scope: the kinds of projects we build, the ranges we run, the typical shape of the work.
