Expert ADU Renovation in Newcastle, CA

ADU renovation in Newcastle gives homeowners a practical way to add living space, rental income, or multi-generational housing on their property. Doug Briggs Construction Inc works with homeowners across Newcastle to update, convert, or expand existing accessory dwelling units on Placer County lots. Newcastle is an unincorporated community, so ADU projects fall under Placer County's planning and building department rather than a city municipality. Many properties in the area also rely on private wells and septic systems, which means utility connections for a renovated ADU need careful coordination with Placer County Environmental Health. Our team handles scope planning, structural updates, interior finishes, and system upgrades from start to finish. Whether you have an older garage conversion, a detached structure, or an attached unit that needs a full refresh, we assess what your property needs and build a clear plan. Call Doug Briggs Construction Inc to talk through your Newcastle ADU renovation project.

We remodeled our master bathroom and to this day, it’s my favorite room in our house! Doug helped us navigate the remodel process, and the finished product turned out beautiful! Everyone that worked on this remodel was prompt and professional. Definitely worth the investment! We would highly recommend their team!

I was the Architect on a rehab job with a client that had a 100+ year old mixed use building with 3 apartments over a retail “corner store”. Doug and his crew took on lead paint, extreme dry rot from years of “deferred maintenance” and had to do it all on a very urban lot with almost no setbacks. The project required lots of coordination with City officials - both Building and Preservation, OSHA folks for the scaffolding on sidewalks and County Environmental for the lead paint work. The project was expensive due to the extensive damage and lots of custom millworks to match, but Doug was a trustworthy person for the owner to get the desired result. The project went from an eyesore to a beautifully restored gem for the community that all neighbors greatly appreciated.
