Permit-ready drafting for San Jose ADUs, additions, remodels and new homes — drawn to fit San Jose's zoning and Planning, Building and Code Enforcement (PBCE) requirements.
San Jose is one of the more active permitting cities in the Bay Area, which is good news and bad news for homeowners. The good news: the city has clear, published standards for ADUs, additions and remodels, including the state-mandated ADU allowances San Jose has adopted on top of its own R-1 and R-2 zoning rules. The bad news: plan check reviewers will flag drawings that don't match those standards exactly, and every round of corrections adds weeks. Most of the delays we see on San Jose projects come from plans that were drawn generically and then adjusted after the first rejection, instead of being drawn correctly against San Jose's own checklist from the start.
Detached, attached and junior ADU plans sized and sited to San Jose's setback, height and lot-coverage rules, with the state ADU allowances applied correctly.
Room and second-story addition drawings coordinated with San Jose's height and daylight-plane standards in single-family zones.
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 San Jose PBCE submittal.
We review your lot, existing structure and goals, and confirm zoning constraints specific to your San Jose parcel.
Full construction drawing set — site plan, floor plans, elevations, sections and details — prepared to San Jose's submittal checklist.
Energy compliance and, where needed, structural review coordinated into the same submittal package.
If PBCE comes back with corrections, we revise and resubmit — we don't disappear after the first drawing set goes out.
Two decades drawing plans for San Jose and the surrounding cities, not a generic national template.
Drawings prepared under professional design standards, not just CAD line work.
San Jose'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.
Based in San Jose, working throughout Santa Clara, San Mateo and Alameda counties and the wider Bay Area.
It depends on the project. Many single-family ADUs, additions and remodels in San Jose 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 San Jose 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. 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.
Tell us what you're building and we'll get back to you with next steps — usually within one business day.
