Abodu Construction in Woodside, CA | Seaside Contractors
We’re Seaside Contractors, an independent construction firm that builds and places Abodu ADUs across Woodside through our Home Remodeling in Woodside. We are not authorized by Abodu, but we’ve put their units on Woodside lots with septic systems, wells, and strict design review. What makes our Abodu work different here is that we handle every part of the project: site prep, foundation, utility connections, and the unit itself. Call (833) 589-8103 for a free estimate.
Why Woodside Residents Choose Us for Abodu Service
Most contractors in the Bay Area have never placed an Abodu unit on a Woodside lot, unlike our General Contractor in Woodside. We have. Glen Sorrento, our owner, grew up in Foster City and studied building construction technology at College of San Mateo before spending two-plus decades working the Peninsula. He’s the one who walks your property and tells you straight whether a pier foundation or a slab makes sense given your soil and drainage. That matters in Woodside, where the town’s review process doesn’t reward guesswork.
We know the Abodu One, Abodu Two, and the standard Abodu ADU line the way a mechanic knows a particular engine. That means we spot foundation, drainage, and Chapter 7A compliance issues before the inspector does. We also stock the OEM components that keep your unit weather-tight and the aftermarket parts that keep your finishes looking right without overspending. One contractor. Every trade. Abodu sales & service from a team that handles the whole site, not just the box.

Common Abodu Construction Problems We Solve in Woodside
Here’s what actually comes up with Abodu units in Woodside, and why:
- Foundation settling on clay-heavy soils. Woodside’s soils shift with wet winters and dry summers. A standard slab-on-grade without geotechnical review can crack or settle unevenly. We see this most often when a previous contractor skipped the soil report to save two weeks. We fix it with pier systems or engineered slabs that move less.
- Chapter 7A ignition-resistant compliance failures. Woodside sits in the wildland-urban interface, and the fire marshal checks exterior materials closely. Abodu units generally meet the standard, but certain roof and exterior assembly details can fail WUI inspection if not properly installed. We correct those before final.
- Utility trenching conflicts with septic and well lines. This is the one that costs people the most time. On Woodside lots with private systems, a trencher that finds a leach field or well line the wrong way means rework, delays, and extra engineering. We locate and map everything before we dig.
- Water intrusion from inadequate drainage. Woodside’s winter rain doesn’t miss. If the unit doesn’t have proper swales and downspout extensions, water gets under the door sills and into the floor assembly. We regrade, add drains, and fix the waterproofing details that were skipped.
- Modular joint and finish separation. Abodu units arrive in sections, and over time the joints can show movement. This is normal for prefab, but it needs adjustment and occasional resealing. We do that work and know which aftermarket sealants perform on the Peninsula.
Abodu Service in Woodside: What Local Conditions Mean for Your Equipment
Woodside’s municipal code requires that any ADU on a lot with a private well must demonstrate sufficient well yield for the added demand. That often triggers a new well pump test and water quality analysis, which can add weeks to the permit timeline before anyone touches a foundation. This is a Woodside-specific sequence, not something you’ll face in Redwood City. If your property is on well and septic, the order of operations is everything: apply for the well review early, run the percolation test on the septic side, and only then lock in your Abodu delivery date. On a property off Woodside Road, we placed an Abodu Two where the existing septic system needed a percolation test before the town would approve the ADU. Our crew coordinated with the septic engineer and the town to get the test done and the system upgraded, then installed the unit on a pier foundation to avoid disturbing the leach field. The project passed final inspection with no delays.
Abodu Models & Products We Service in Woodside
We build and service the Abodu One, the Abodu Two, and the standard Abodu Accessory Dwelling Unit. Our parts approach is simple: OEM components for structural and weather-tightness elements, quality aftermarket parts for finishes and fixtures where they meet or exceed spec. We keep the fast-moving items local so a Woodside job doesn’t stall waiting on a shipped seal or bracket. For larger structural repairs, we assess whether the modular design allows a targeted fix or whether a partial rebuild is the more durable play. In Woodside’s wet winters and hot summers, we lean toward the fix that survives ten seasons, not the one that looks done this week. Woodside service area coverage means we’re not driving from San Jose while your unit sits open.

FAQs – Abodu Construction in Woodside
Yes. Adding a bathroom or bedroom to a septic-served Woodside lot typically triggers a percolation test to confirm the system can absorb the added flow. If it can’t, you’ll need a system upgrade before the ADU permit is final. We coordinate that test and the upgrade so it doesn’t stall the project. Call (833) 589-8103 and we’ll walk you through the sequence.
Most Woodside slopes can hold an Abodu unit, but it often requires a pier or grade-beam foundation instead of the standard slab. We’ve placed units on hillsides throughout the Santa Cruz Mountains and offer Abodu service in San Carlos. The key is a geotechnical review early, because that dictates the foundation design and cost.
Your Abodu must comply with Chapter 7A ignition-resistant construction standards. That covers the roof covering, exterior walls, vents, and deck materials. We verify every component against Woodside’s current WUI checklist during installation and before the final inspection. This is not something to trust to a contractor who’s never worked the wildland-urban interface.
Most Woodside Abodu permits run three to five months from application to approval, but that timeline stretches if the well yield review or percolation test surfaces issues. The design-review step can add time too. We start with the well and septic verification because those are the slowest-moving pieces. Call (833) 589-8103 for a realistic timeline on your specific lot.
Yes, that’s exactly what we do. We handle grading, foundation, utility trenching, drainage, and the unit placement as one scope. This is the difference between one accountable contractor and three subs pointing at each other when the inspector asks about the leach field clearance. We manage the whole sequence under one permit set.
