New Builds, Remodels & ADUs in Petaluma
Northern Hills Construction is a licensed general contractor serving Petaluma and greater Sonoma County.

One crew and one point of contact, from the first sketch to the final inspection.






Our proven 3-step method for planning, permitting, and building in Petaluma.
1. Consultation & Site Review
Every project starts with your property and your goals. We walk the site, talk through scope and budget, and tell you honestly what is feasible before any design work begins.
2. Design & Permitting
We coordinate the design and submit the plans - to the City of Petaluma's building department for in-town projects, or to Permit Sonoma for county properties - and manage the review through approval.
3. Construction & Closeout
One crew and one point of contact, from groundbreaking to final inspection. We schedule every inspection and walk the finished project with you at closeout.

From custom new homes to remodels, additions, and ADUs, we build across Petaluma and Sonoma County with our own crew. Here is what we can do for your property.

New Home Construction
Custom homes built by our own crew, from foundation to finish. We manage the entire build - design coordination, permits, construction, and final walk-through.

Remodels & Additions
Kitchen, bath, and whole-home remodels plus room additions. One crew handles the work from demolition to the final finishes.

ADUs & Garage Conversions
Backyard cottages, garage conversions, and in-law units. We check what your lot allows, handle the permits, and build the unit start to finish.
