Comprehensive Service Catalog
From custom homes and commercial projects to remodels and ADUs, we provide architectural design and permit coordination, with plans prepared in accordance with California building codes, local city requirements, and applicable ADA accessibility standards.
Turnkey Execution & Clarity
No finger-pointing, no surprise change orders. Four milestones, one team accountable for every one of them.
We check zoning, setbacks and HOA rules before you spend a dollar on design.
Your must-haves become a floor plan you can walk through in 3D.
We prepare the full drawing set and handle every city comment until your permit is approved.
The plans are 100% yours. Take them to any contractor and compare bids.
The Turnkey Advantage
Most projects stall in the handoff between designer and contractor, and you end up in the middle. We keep design, drafting and permits under one roof, so one person is accountable from start to finish.
Heritage, Leadership & Local Presence
Founded in 2014, Jean-Prescott Studio is an independent California design studio built on precise drafting and long-term clients.
Jeannice Carrillo runs point on every project this design firm takes on over a decade of hands-on work in California zoning codes, coastal regulations, and construction planning. There’s no junior team quietly handling your file. If Jeannice’s name is on the proposal, Jeannice is on your design set, your 3D visualization, and your calls with the city.
We already know your city’s building department. We handle site measurements, walkthroughs and city meetings in person.
