ActiveYards Home Additions & ADU: The San Jose Owner’s Guide
An ActiveYards home addition or ADU project in San Jose typically runs $53,100 to $153,400 installed, depending on square footage, foundation type, and finish level. Bradford Remodeling Co San Jose stocks the framing hardware, fasteners, and structural components needed for ActiveYards-compatible builds, and we install on a written scope with a fixed price before the first board goes up. Most owners call us because a permit review flagged a non-compliant detail, a foundation pour went wrong, or the original contractor walked off mid-rough-in. If your ActiveYards addition is half-framed, sagging, leaking, or stuck in permit limbo, we can step in and square it away.
Straight number, written scope, done when we said done.
Which ActiveYards Models This Applies To
ActiveYards sells through authorized dealers, not direct to homeowners, so the “model” is often recorded on your sales invoice or stamped on the materials list attached to your permit application. The most common ActiveYards-compatible additions in San Jose are detached ADUs built off their pre-engineered steel or wood framing kits, plus room extensions that tie into existing slab-on-grade or raised foundations. What matters for parts and labor: whether your addition is panelized (pre-cut walls shipped flat) or stick-framed on site, and whether the foundation is concrete slab, raised, or pier-and-beam. That single detail changes the anchor bolt spec, the sill plate sizing, and the shear wall requirements. Pull your permit drawings and look for a foundation detail page. If you cannot find it, we will match the right hardware by measuring the existing anchor spacing and plate thickness.
For ActiveYards builds specifically, the OEM hardware package is solid, but the lag screws and tie-downs included in the kit are sometimes sized for midwest wind loads, not California seismic requirements. We routinely swap in Simpson Strong-Tie or USP connectors with higher rated capacities to meet San Jose building code without changing the frame layout. Bradford Remodeling Co San Jose is an independent contractor, not affiliated with ActiveYards, so we match or upgrade parts without being tied to a kit list.

Signs Your ActiveYards Home Additions & ADU Is Failing
- Cracks at the wall-to-ceiling joint wider than 1/8 inch. This usually means the top plate or truss connection shifted, often because the kit’s original strapping was under-torqued or missing entirely.
- Doors or windows that bind after the first heavy rain season. ActiveYards panels can swell or settle if the sill plate was not flashed correctly, a common failure in San Jose’s clay-heavy soils that expand and contract with moisture.
- Moisture staining on the interior drywall near the floor line. That points to improper sill sealing at the foundation, which is a weep-screed and membrane issue, not just a paint fix.
- Visible rust or corrosion on steel framing connections. San Jose’s coastal influence plus irrigation overspray accelerates this. Once the connector rusts through the zinc coating, it needs replacement, not wire brushing.
- Squeaking floors that get worse, not better, over time. In raised-floor additions, this means the engineered lumber or joist hangers were installed without the correct bearing tolerances, and the movement is chewing through the substrate.

DIY or Call Us?
You can check your own foundation vents, look for visible connector rust, and confirm whether your permit card is posted. You should not attempt to lift, shim, or re-anchor a framed addition yourself. A failed sill connection or under-sized shear wall is not a handyman fix; it is a structural issue that affects whether the building stays on its foundation during a seismic event. San Jose is in a high-seismic zone, and the difference between a correctly installed connector and a guess is measured in inches of building movement. If your ActiveYards addition shows cracks, sag, or separation, call (669) 272-2637. We will send a background-checked, uniformed technician to assess the framing, give you a written price, and explain exactly what the fix involves.
FAQs
A properly installed ActiveYards addition should last 50 years or more, but the steel connectors and sill hardware often need attention at the 7 to 10 year mark in San Jose’s clay soil and dry-summer climate. The framing itself rarely gives out; the connections and flashing do. Call (669) 272-2637 to schedule a structural check with a written report.
In most cases, yes. We repair shear wall deficiencies, replace corroded connectors, resquare sagging floors, and correct sill flashing without taking the structure down. A full teardown is only necessary when the framing has rotted through or the foundation itself has shifted beyond acceptable tolerance.
Most connector replacements and sill repairs take 1 to 3 days on site, plus time for permit review and inspections with the San Jose building department. We stage materials before we start, so your project does not sit open to weather between steps.
Our trucks carry Simpson Strong-Tie and USP connectors, anchor bolts, sill seal, and flashing in the common sizes used on ActiveYards builds in San Jose. If your job needs a specific engineered hanger or hold-down, we order it from our supplier network and have it on site before the permit is approved. Bradford Remodeling Co San Jose also carries parts for KraftMaid, Cambria, and Silestone product lines, so your interior finishes can be matched in the same job as the structural repair.
If your ActiveYards home addition or ADU is showing cracks, sag, or moisture, call (669) 272-2637 for a free estimate. A live person answers, day or night, and your written price is guaranteed before the first tool comes out.
