Permit-ready drafting for Union City ADUs, additions, remodels and new homes — drawn to fit Union City's zoning and building department requirements.
Union City sits in Alameda County, and its housing stock tends to be more attainable than what you'll find across the county line in Santa Clara County — a mix of older subdivisions from the city's early growth years and newer development closer to BART and the Union City Intermodal Station. That affordability, combined with Union City's diverse, multigenerational households, has made ADUs one of the most requested projects we see here, both for family members who want to stay close and for rental income. The city's plan check process expects the same level of detail as anywhere else in the Bay Area, and drawings that don't match Union City's own zoning and building standards will come back with corrections regardless of how straightforward the project looks.
Detached, attached and junior ADU plans sized and sited to Union City's setback, height and lot-coverage rules, with the state ADU allowances applied correctly.
Room and second-story addition drawings coordinated with Union City's height and design standards for 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 Union City's building department submittal.
We review your lot, existing structure and goals, and confirm zoning constraints specific to your Union City parcel.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to Union City'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 Union City and the surrounding cities, not a generic national template.
Drawings prepared under professional design standards, not just CAD line work.
Union City'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 Union City 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 Union City single-family and multi-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. Given how many Union City households are multigenerational, we regularly draw ADUs meant for family members as well as ones meant for rental income — either way, we confirm eligibility for your specific parcel first.
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.
