Permit-ready drafting for Cupertino ADUs, additions, remodels and new homes — drawn to fit Cupertino's strict R-1 single-family standards and design review process.
Cupertino runs one of the more particular plan check and design review processes in the Bay Area, and that's by design — the city's R-1 single-family zoning comes with detailed standards on setbacks, height and neighborhood compatibility, and reviewers hold drawings to them closely. Additions and new construction can draw design review scrutiny that a straightforward project in a less exacting city wouldn't face. Parts of Cupertino also sit in hillside areas, which come with their own grading and height considerations on top of the base R-1 rules. Plans that treat Cupertino like a generic R-1 city, without accounting for its specific standards, tend to draw corrections. We draw against Cupertino's actual requirements, hillside terrain included where it applies.
Detached, attached and junior ADU plans sized and sited to Cupertino's R-1 setback, height and lot-coverage rules, with the state ADU allowances applied correctly.
Room and second-story addition drawings coordinated with Cupertino's height and neighborhood-compatibility standards in single-family zones.
Interior and exterior remodel drawings for kitchens, baths and whole-house renovations, including scope that triggers Cupertino's design review process.
Ground-up custom home drawings and garage-to-living-space conversions prepared for Cupertino submittal, including hillside-area requirements where applicable.
We review your lot, existing structure and goals, and confirm the R-1 and, if applicable, hillside constraints specific to your Cupertino parcel.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to Cupertino's submittal checklist.
Energy compliance and, where needed, structural review coordinated into the same submittal package.
If Cupertino comes back with corrections, we revise and resubmit — we don't disappear after the first drawing set goes out.
Two decades drawing plans for Cupertino and the surrounding Santa Clara County cities, not a generic national template.
Drawings prepared under professional design standards, which matters in a city where design review carries real weight.
Cupertino's R-1 ordinance and design review standards get updated — we draw against the current version, not last year's.
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 Cupertino 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.
Cupertino gives extra scrutiny to additions, new construction and anything that changes a home's exterior massing, weighing it against neighborhood compatibility and, in hillside areas, slope and grading standards. We prepare drawings with that review in mind rather than treating Cupertino like a standard R-1 city.
Turnaround varies by submittal volume and project scope — simple ADU plans generally move faster than additions or new construction that trigger design review. We can't promise a city timeline, but drawings prepared against Cupertino's actual standards are the biggest lever on how many correction cycles you go through.
Most Cupertino single-family lots qualify for at least one ADU under state and local rules, subject to setback, height and lot-coverage limits that vary by zoning district — and, on hillside parcels, additional grading considerations. We confirm eligibility for your specific parcel 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.
