Permit-ready drafting for Sunnyvale ADUs, additions, remodels and new homes — drawn to fit Sunnyvale's zoning and building department requirements.
Sunnyvale is one of the most built-out cities in Santa Clara County, with a dense concentration of tech employers and housing costs that have pushed a lot of homeowners toward adding space on their existing lot instead of moving. Most residential parcels in Sunnyvale run small to mid-size, which means setback, lot-coverage and height limits matter on almost every project — there's rarely extra room to absorb a drawing mistake. ADUs in particular get a lot of interest here, both for extended family and for rental income, and the city's plan check reviewers are used to seeing ADU applications, but they still expect the drawings to match Sunnyvale's own standards exactly.
Detached, attached and junior ADU plans sized and sited to Sunnyvale's setback, height and lot-coverage rules, with the state ADU allowances applied correctly.
Room and second-story addition drawings coordinated with Sunnyvale's height and daylight-plane standards on 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.
Ground-up custom home drawings and garage-to-living-space conversions prepared for Sunnyvale's building department submittal.
We review your lot, existing structure and goals, and confirm zoning constraints specific to your Sunnyvale parcel.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to Sunnyvale's submittal checklist.
Energy compliance and, where needed, structural review coordinated into the same submittal package.
If the city comes back with corrections, we revise and resubmit — we don't disappear after the first drawing set goes out.
Two decades drawing plans for Sunnyvale and the surrounding cities, not a generic national template.
Drawings prepared under professional design standards, not just CAD line work.
Sunnyvale's ADU program and zoning ordinances get updated — we draw against the current standard, 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 Sunnyvale 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, and can coordinate engineering review as part of the drawing package.
Turnaround varies by submittal volume and project scope — simple ADU plans move faster than full remodels or new construction. We can't promise a city timeline, but we can promise your drawings won't be the reason for a correction cycle: getting it right on the first submittal is the single biggest lever on total time.
Most Sunnyvale single-family lots qualify for at least one ADU under state and local rules, even on smaller parcels — the state ADU allowances were written with exactly this kind of lot in mind. Setback, height and lot-coverage limits still apply and vary by zoning district, so we confirm eligibility for your specific parcel during the site walk before we draw anything.
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.
