Fast, Reliable General Contractor Across San Jose
Seaside Contractors manages full-scope residential construction throughout San Jose, from kitchen and bathroom remodels to additions, garage conversions, and ADUs. We work the 95110 – 95113 core, Willow Glen, Alum Rock, and the surrounding ZIPs, so we know exactly what San Jose’s permit desk, building code, and lot conditions actually require. If you’re planning a remodel or addition in San Jose, call us at (833) 589-8103. We’ll give you a straight answer about scope, schedule, and cost before you spend a dollar.

Why Seaside Contractors Is San Jose’s Preferred General Contractor Company
San Jose homeowners come to us because we run the whole job under one accountable team. Our General Contractor team handles structural work, finishes, and everything in between, so you’re not juggling three specialty subs and hoping their schedules align. Glen Sorrento leads each project with a simple rule: the quote you approve is the job we build, and any permit problem gets solved before it becomes your problem.
We’ve completed remodels and additions in San Jose ZIPs like 95103, 95106, 95108, and 95109, including a 1950s rancher in the 95112 area where the framing needed seismic upgrades before the addition could pass inspection. That project taught us what most remodels in this city eventually reveal: older stucco-over-wood-frame homes were not built to current wind and seismic standards. We plan for that upfront, not after the inspector flags it.
Our San Jose customers tell us the difference is documentation. We pull permits, schedule inspections, and keep every structural upgrade on record. That matters when you sell the house or file an insurance claim. It’s the kind of rigor homeowners expect from a General Contractor who builds in the Bay Area’s stricter jurisdictions.

General Contractor Services in San Jose
General Contractor Services in San Jose means running the entire scope from planning through final inspection: demo, structural work, rough-in, finish work, and all the permits in between.

When you hire us as your General Contractor in San Jose, you get one point of contact for every trade. We coordinate engineering, framing, electrical, plumbing, waterproofing with Schluter systems, and finish carpentry. You’re not stitching together bids from three companies and praying they communicate.
What a full-scope contractor handles
A full-scope contractor in San Jose handles the structural corrections that older homes need before any finish work can start. That includes shear-wall upgrades, foundation anchoring, and roof-to-wall connections rated for local wind and seismic loads. We also manage the finish selections, from cabinetry and countertops to tile and fixtures, so the project doesn’t stall while you chase down a backsplash vendor.

When you actually need us
You need a general contractor in San Jose when the project touches structure, layout, or systems. Adding square footage, converting a garage, or building an ADU on a narrow lot in the 95110 – 95113 core is not a handyman job. If the work needs a structural engineer, a permit set, or an inspection sign-off, that’s our conversation.

Construction Company in San Jose
Construction Company work in San Jose runs on knowing the city’s Title 24 wind and seismic load requirements, because inspectors here check. A compliant quote for a San Jose addition or ADU includes structural calculations, shear-wall details, and approved tie-down hardware. A cheap bid often leaves those out and then hits you with change orders after the first failed inspection.
Our Construction Company team has been through the San Jose permit process enough times to anticipate what the plan check will flag. We don’t submit drawings we know will bounce. We submit drawings that account for the heritage-tree ordinance, setback rules, and load requirements specific to your lot.
Structural scope in older San Jose homes
Homes built in the 1940s through 1970s in San Jose were framed before modern seismic code. When we open up a wall for an addition, we regularly find studs that need shear reinforcement and foundations that need anchor bolts. That’s not a surprise change order. That’s a line item we budget for from the start because we build in San Jose.

Permitting and inspections
We pull all permits in-house in San Jose and manage the inspection schedule through final sign-off. For structural work, we coordinate third-party structural observation where San Jose requires it. For projects on lots with mature oaks or redwoods, we pull the arborist report and tree permit before the foundation plan is locked. That sequencing prevents the three-week stall that turns a well-planned addition into a job site with no crew.
Trusted Brands We Service in San Jose
On San Jose projects, we regularly specify Toto and American Standard fixtures for bathrooms, Schluter waterproofing membranes behind tile and shower pans, and Sterling products for value-engineered bath packages. Because we work with 50+ brands across every trade, we’ll match the material to the project and budget, not force you into a single product line. Our San Jose clients get straightforward recommendations with local availability in mind, so materials don’t sit on backorder while the job waits. When you’re choosing a countertop, a tub filler, or a waterproofing system, we can explain the performance difference and what’s worth paying for in San Jose’s housing market.

AfterCommon General Contractor Problems We See in San Jose Homes
- Failed shear-wall inspections on older stucco ranchers. Original 1950s framing doesn’t meet current wind-load requirements, and inspectors flag it every time. We upgrade shear walls and connections before finish work begins.
- Heritage-tree ordinance surprises on lot-splits and additions. A mature oak in the backyard of a 95111 or 95112 home can require a city permit and arborist review before any foundation work. We run that check before plans are submitted, not after.
- Non-compliant hurricane straps and ties. Generic straps often don’t meet San Jose’s seismic and wind specs, causing permit rejection. We specify and install approved Simpson Strong-Tie hardware rated for local conditions.
- Tight-lot additions with no room to build out. San Jose lots are narrow and shallow, so additions go up. That means engineering for vertical loads, second-story shear, and foundation capacity all at once. We plan the full structural picture before the first wall comes down.
Pricing for General Contractor in San Jose, CA
General contractor pricing in San Jose tracks the scope and structural condition of your home. Here are the ranges we see for the most common project types:
| Project Type | Typical San Jose Range |
|---|---|
| Home Addition | $53,100 – $153,400 |
| ADU Construction | $106,200 – $259,600 |
| Garage Conversion | $35,400 – $94,400 |
What moves the number is structural work. A home addition on a 1950s rancher that needs shear-wall upgrades and foundation anchoring will land higher in the range than a straightforward addition on a newer build. We quote structural corrections as they actually are on your house, not as a generic allowance. Call (833) 589-8103 for a written, line-item estimate. It’s free, and we’ll walk you through exactly what San Jose requires for your specific project.

FAQs About General Contractor in San Jose
San Jose enforces Title 24 wind and seismic load requirements, which means additions and ADUs must be engineered for specific lateral-load ratings based on your lot’s exposure and building height. The structural drawings must show shear-wall locations, connection details, and foundation anchoring. We handle those calculations with a licensed engineer before we pull permits. Call (833) 589-8103 if you’re sizing an addition or ADU and want a straight read on what your specific site will require.
It can trigger an arborist report and a tree permit before the city will approve foundation or shear-wall work within a protected tree’s drip line. That means a mature oak or redwood in your setback could delay your plans by weeks if it’s not handled at the start. We front-load the tree check so your plans don’t get caught mid-review. Call (833) 589-8103 and we’ll check your lot before you commit to a design.
A compliant quote in San Jose includes structural engineering, shear-wall upgrades, approved tie-down hardware, permit fees, and inspection scheduling. Cheap bids often exclude those line items, then present them as change orders after the first failed inspection. Ours includes them from the first written estimate. Call (833) 589-8103 for a quote that matches what the inspector will actually require, not what the salesperson wants you to compare.
Insurance carriers in California look for documented structural upgrades when you file a claim or apply for a new policy. If your addition or ADU can’t show permitted shear-wall and connection work, a claim involving structural damage can get complicated or reduced. We keep your permit records, inspection reports, and structural observation documentation organized for exactly that purpose. Call (833) 589-8103 if you’re planning a project and want the compliance trail that insurance companies respect.
Yes, in most cases. San Jose’s SB 9-era policies and ADU ordinances allow ADUs on lots that older zoning would have rejected, but setbacks and height limits still govern the actual footprint. A detached ADU on a narrow San Jose lot often fits best with a compact floor plan and a carefully placed foundation that respects the side and rear setbacks. We design to the lot, not the other way around. Call (833) 589-8103 to have us look at your parcel and give you an honest buildability answer within a week.
