Our Services

One Team. One Process. Total Control. Unlike companies that outsource everything, we offer a fully integrated approach:

ADU Construction

From foundation to final finishes, we build fully functional, high-quality ADUs tailored to your property. Every project is designed for durability, comfort, and long-term value. We manage the entire build so you get stress-free experience.

Interior Finishing & Design

We complete your ADU with high-quality interior finishes that make it feel like a true home. From flooring and cabinetry to lighting and fixtures, every detail is carefully selected for durability and style.

Roofing

A strong, reliable roof is essential to protect your investment. We install and upgrade roofing systems that are built to last and designed to complement your ADU. Our team ensures proper insulation, ventilation, and weather resistance.

Solar

Reduce utility costs and increase energy efficiency with integrated solar solutions. We design systems that align with your ADU’s usage and long-term savings goals. Clean energy, lower bills, and greater property value—all in one.

HVAC

Comfort matters. We install modern, energy-efficient heating and cooling systems to keep your ADU comfortable year-round. Our solutions are tailored for performance, quiet operation, and cost efficiency.

Electrical

Safe, reliable electrical systems are the backbone of every ADU. From wiring to lighting and panel upgrades, we handle it all with precision and code compliance. Everything is built to support modern living and future needs.

Customers Reviews

I’ve been in construction a long time, and I can tell you — not every company delivers what they promise. Prime Time ADU stands out. Their team is organized, knowledgeable, and they understand how to actually execute a project from start to finish. The level of detail, coordination, and professionalism they bring is what you expect from a top-tier builder. If you’re looking to build an ADU the right way, these are the people you want on your project.

Builder

We wanted an ADU for my parents but had no idea where to start. Prime Time handled everything — design, permits, construction — and made the process incredibly smooth. The finished space feels like a real home, not an add-on

— Andrew Maceranka
We watched Jim and the Prime Time crew build a $12 million home on the bay, so we assumed our smaller project wouldn’t even be on their radar. We were wrong. Jim and his team took on our 892 sq. ft. ADU with the same level of professionalism and attention to detail. The project came in under budget, and now the rental income helps cover our property taxes. It completely changed how we use — and benefit from — our property.
— Charlie Morgardo
Cape Cod

Prime Time built a 900 sq. ft. home in our backyard, and it’s completely changed our lives. The house runs on solar with heat pumps and is fully electric — we essentially have no utility bills. What means the most is that this allows my 86-year-old mother to live comfortably, independently, and without the burden of monthly expenses. Outside of cable and her cell phone, she’s living free and clear. It’s not just an addition — it’s peace of mind for our entire family.
