Local Intelligence
What Gilroy Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Gilroy — Building Division will not accept a permit application without them. Gilroy's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Gilroy does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Gilroy who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,123/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $3,000 to $23,000 depending on project valuation and scope. Plan check runs approximately 5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building Division as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Building Division ↗Construction Cost Context
Gilroy's adu / renovation construction costs run $250–$500 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Gilroy
Gilroy's impact fees hinge on a hard 750-square-foot cliff: build at 749 square feet and you owe nothing in city impact fees, but cross into 750 and you're suddenly on the hook for roughly $19,000 in Public Facilities, Sewer, Traffic, and Water fees stacked together. Many homeowners design their ADU around this threshold only to find out mid-plan-check that Santa Clara County's own sewer lateral inspection requirements add another delay, since the county — not the city — signs off on that connection. Because Gilroy sits in Seismic Zone D, expect the Building Division to scrutinize foundation and shear wall details closely even on single-story detached units, which is a common source of plan check rejections that push projects past the advertised 5-week timeline.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience working with Gilroy homeowners, that 5-week plan check timeline and the per-square-foot cost figure are both state-level estimates, not numbers pulled from actual local permits — I'd call the Gilroy Building Division directly and get quotes from two or three local contractors before penciling in a budget or start date. I've also seen even straightforward submittals stretch past 8 weeks once you factor in a corrections round, so don't bank on that 5-week figure holding up if your drawing set isn't fully dialed in on the first pass."

Common Questions
Gilroy Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Gilroy? +
You need accurate floor plans for: permit applications (required by Gilroy's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Gilroy? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Gilroy's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Gilroy? +
Our floor plan drafting packages for Gilroy cover measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Gilroy home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Gilroy neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Gilroy building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Gilroy? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Gilroy. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Gilroy? +
In Gilroy, where median home values are around $900,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Gilroy? +
Yes — Gilroy's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Gilroy? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Gilroy homes built before the 1990s.
