Expert Garage Conversion in Newcastle, CA

Garage conversion is one of the most practical ways Newcastle homeowners can add livable square footage without expanding their footprint. Doug Briggs Construction Inc handles the full scope of work: structural assessment, insulation, framing, electrical, plumbing rough-in, and interior finishing. Newcastle sits in unincorporated Placer County, where single-family lots commonly carry attached or detached garages with real conversion potential. Under Placer County rules, converting a garage to an ADU does not require replacement parking spaces, which removes one of the biggest barriers homeowners worry about. Many Newcastle properties feature older garages that need structural upgrades to meet current California Residential Code before they can serve as habitable space. We assess each structure before any work begins so there are no surprises mid-project. Whether you want a rental unit, a space for family, or a dedicated home office, a garage conversion puts that square footage to work. Call us to talk through what your Newcastle property can support.

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.
