Permit-ready drafting for Campbell ADUs, additions, remodels and new homes — drawn to fit Campbell's zoning and the tight, mostly built-out lots common across the city.
Campbell is one of the smaller, more built-out cities in Santa Clara County, and it shows in the lots: many Campbell parcels are narrower and more tightly built than in neighboring cities, which makes setback, lot-coverage and parking details carry more weight in plan check. That same tight lot stock also makes Campbell a strong market for ADUs — plenty of homeowners have just enough side or rear yard to add a detached unit, provided the drawings account for coverage and access correctly from the start. Plans that don't measure a Campbell lot's actual buildable envelope tend to come back with corrections on setback or coverage. We draw to your parcel's real dimensions, not an assumed standard lot.
Detached, attached and junior ADU plans sized and sited to fit Campbell's tighter lot dimensions, with setback, coverage and access worked out before submittal.
Room and second-story addition drawings coordinated with Campbell's height and setback standards on the city's typically smaller single-family lots.
Interior and exterior remodel drawings for kitchens, baths and whole-house renovations, including scope that triggers a full plan check submittal in Campbell.
Ground-up custom home drawings and garage-to-living-space conversions prepared for Campbell's submittal process, sized to fit built-out lots.
We review your lot, existing structure and goals, and confirm what actually fits given Campbell's setback and coverage limits on your parcel.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to Campbell's submittal checklist.
Energy compliance and, where needed, structural review coordinated into the same submittal package.
If Campbell comes back with corrections, we revise and resubmit — we don't disappear after the first drawing set goes out.
Two decades drawing plans for Campbell and the surrounding South Bay cities, including tight, built-out lots.
Drawings prepared under professional design standards, not just CAD line work.
Campbell's smaller parcels leave less margin for error on setback and coverage — we confirm your buildable envelope before we draw, not after a rejection.
You work directly with the person drawing your plans, from first sketch through plan check corrections.

It depends on the project. Many single-family ADUs, additions and remodels in Campbell 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. We'll tell you upfront whether your project needs one.
Often, yes — state ADU law sets minimum allowances that many of Campbell's smaller, built-out parcels still meet, though setback and coverage limits get tighter as the lot gets smaller. We confirm what actually fits on your specific parcel during the site walk.
Turnaround varies by submittal volume and project scope — simple ADU plans generally move faster than full remodels or new construction. We can't promise a city timeline, but drawings prepared against Campbell's actual lot dimensions are the biggest lever on how many correction cycles you go through.
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.
Both. Some clients come to us directly and hire their own contractor afterward; others are referred by a contractor who wants drafting handled by a dedicated specialist rather than in-house.
Tell us what you're building and we'll get back to you with next steps — usually within one business day.
