About the company
Milkyway Construction Inc is a California corporation founded in 2019 (successor to Milkyway Construction LLC). Because we hold the Class B general building, C-10 electrical, and C-57 well drilling classifications, structure, electrical, and wells stay under one contract and one schedule — no hand-offs between separate trades when inspections and sequencing get tight.
Our work centers on the San Gabriel Valley and Greater Los Angeles: residential construction and ADUs, multi-family work, commercial tenant improvements for retail and food businesses, electrical service work, and well drilling. We coordinate permits, MEP sub-permits, utility meter applications, and city inspections, and we track construction-waste diversion compliance digitally for every project that requires it.
Energy is part of the same job for us. We design and install solar photovoltaic (PV) systems for both residential and commercial properties — rooftop arrays, inverters, and battery storage, with utility interconnection handled end to end — and we operate solar generation on our own commercial properties. Our materials and equipment move on our own Tesla Semi electric trucks, based in Pomona, so the fleet that builds the project is zero-emission too.
The company is led by its president, David Dai, who is also a California-certified backflow tester — useful on projects where plumbing compliance and testing have to close out cleanly.
What we do
Seven core lines of work, all performed under our own CSLB license. If a project needs a trade outside our classifications, we coordinate licensed specialty subcontractors under our contract.
New construction and major renovations for residential and multi-family properties, handled from groundwork through final inspection.
Detached ADUs and garage-to-ADU conversions, including the permit, utility, and compliance work that comes with them.
Interior build-outs for retail, restaurant, and bakery tenants — coordinated with landlords, health departments, and city plan check.
Licensed electrical work for our own projects and as a standalone service, from panels to full building systems.
Design and installation of solar PV systems for homes and businesses — from a single-family rooftop to large commercial arrays — permitted, installed, and interconnected by our own licensed electrical team.

How it works
A straightforward process, with the paperwork handled for you.
We walk the property, talk through what you want to build, and flag permit, utility, and code issues up front — before they become change orders.
You get a written scope and price. We prepare and submit permit applications, MEP sub-permits, and meter requests, and respond to plan-check corrections.
Our crews and licensed subs build to plan. We schedule every inspection, close out compliance items, and hand over a finished, signed-off project.
