Permit-ready drafting for ADUs, additions, remodels and new homes across the wider Bay Area — drawn to fit whichever city or county's zoning and permitting requirements apply to your address.
There's no single "Bay Area" building department. Every city — and every unincorporated area — runs its own plan check process, with its own zoning code, its own ADU ordinance, and its own submittal checklist. Our core service pages cover San Jose and the cities we work in most, but we also take on projects for homeowners elsewhere in the region who want a drafter who already knows how to work with a Bay Area building department, not one specific city's. The work is the same either way: confirm which jurisdiction actually governs your parcel, then draw to that jurisdiction's real standard instead of a generic template. Send us your address and we'll confirm coverage before anything else.
Detached, attached and junior ADU plans sized to state ADU law and whichever local setback, height and lot-coverage rules apply to your specific city or county.
Room and second-story addition drawings coordinated with your local jurisdiction's height and zoning standards for single-family homes.
Interior and exterior remodel drawings for kitchens, baths and whole-house renovations, scoped to whatever triggers a full plan check submittal where you live.
Ground-up custom home drawings and garage-to-living-space conversions prepared for your local building department's submittal process.
We review your lot, existing structure and goals, and identify which city or county's zoning rules actually govern your project.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to your local building department's submittal checklist.
Energy compliance and, where needed, structural review coordinated into the same submittal package, wherever you're building.
If your building department comes back with corrections, we revise and resubmit — we don't disappear after the first drawing set goes out.
Two decades drawing plans across San Jose and the wider region, not a single-city playbook stretched to fit everywhere.
Drawings prepared under professional design standards, not just CAD line work.
Every Bay Area city and county runs its own zoning and ADU ordinance — we look up the current standard for your specific address instead of assuming it matches the city next door.
You work directly with the person drawing your plans, from first sketch through plan check corrections.
Based in San Jose, working throughout Santa Clara, San Mateo and Alameda counties and the wider Bay Area.
Our core service pages cover San Jose and the cities we work in most often, but we regularly draft for homeowners elsewhere in the Bay Area too. Send us your address and a rough scope and we'll confirm coverage and give you a realistic sense of what your local building department will require.
It depends on both the project and the jurisdiction. Many single-family ADUs, additions and remodels can be permitted with drafted plans alone, but structural elements — retaining walls, second-story additions, some new construction — often require a licensed engineer's stamp regardless of where you're building. We'll tell you what your specific city requires before we start.
It varies a lot by jurisdiction, and by how busy that department is when you submit — there's no single Bay Area timeline. We can't promise a city's schedule, but drawings prepared against your jurisdiction's actual checklist move through review faster than generic plans do.
Most California single-family and multi-family lots qualify for at least one ADU under state law, though setback, height and lot-coverage limits still vary by city and zoning district. We confirm eligibility for your specific parcel and jurisdiction during the site walk.
Both, if you want it bundled. We prepare Title 24 / CF1R energy compliance documentation alongside the architectural drawings so the whole package is coordinated and submitted together — see our Title 24 & CF1R services for details.
A site address, rough scope of what you want to build, and — if it exists — a copy of your current property survey or existing floor plan. If you don't have a survey, we can help you get one.
Tell us what you're building and we'll get back to you with next steps — usually within one business day.
