General Contractor in Lakewood, Colorado

Lakewood is one of Jefferson County's largest cities, and 303 Construction has been building here for over two decades. From mid-century rancher renovations to new construction and commercial build-outs, we deliver full-service general contracting across every Lakewood neighborhood.

Lakewood's housing stock is diverse — mid-century homes near Belmar, newer construction near Green Mountain, and everything in between. Each property type presents different opportunities and challenges, and our 20+ years of local experience means we've handled them all.

We manage every aspect of your construction project: permits with the City of Lakewood, design coordination, all trades (framing, electrical, plumbing, HVAC, finish work), and final inspections. You get one contract and one point of contact from start to finish.

Whether you're updating a dated kitchen, finishing your basement, replacing a hail-damaged roof, or building an outdoor living space to enjoy Lakewood's mountain views — 303 Construction has the experience and team to deliver quality results on time and on budget.
