Abodu Construction in Pomona, CA | Sycamore Contractors
We’re Sycamore Contractors, an independent construction firm serving Pomona with full-scope Abodu installation, site work, and Abodu service in Claremont and nearby areas. The short version: we handle the foundation, utilities, grading, and drainage work that decides whether an Abodu unit actually clears Pomona building inspections. Most Abodu owners here don’t need a new unit, they need the ground under it fixed, the panel upsized, and the drainage reworked. Call (877) 265-6284 and we’ll tell you straight what your lot needs.
Why Pomona Residents Choose Us for Abodu Service
Most contractors in Pomona see an Abodu as a drop-and-go product. We don’t, because Pomona’s lots rarely cooperate. We’ve set units behind Craftsman bungalows in Wilton Heights, behind post-war tract homes in the 91768 corridor, and on infill lots where the original 1920s concrete is still doing the holding. Nate Calloway grew up in Temecula and has spent his career on foundations, framing, and the kind of retrofit work Pomona’s older housing stock demands. He’ll tell you the same thing he tells every homeowner: a prefab unit is only as good as the pad it sits on and the utilities feeding it. We bring Abodu sales & service knowledge to a city where the host house is usually a century old. That combination matters more here than almost anywhere else in the county. We work for you, not the factory. We pull permits, coordinate the engineer, and handle the site conditions Abodu’s factory plan never anticipated.

Common Abodu Construction Problems We Solve in Pomona
- Uneven settling on old fill and expansive clay. Pomona’s pre-war lots often have unengineered fill behind the house. Factory-set pads and leveling hardware settle unevenly within a season, throwing doors and finish joints out of alignment. We re-level, add engineered fill where needed, and correct the pad before it gets worse.
- Electrical panels already at capacity. A 1920s or 1950s Pomona house was never wired for a second dwelling. The original service often can’t carry an Abodu One’s panel, let alone a Two. We upsize the service and the subpanel so the unit runs without tripping the main.
- Sewer laterals that can’t handle the add-on. Older Pomona laterals are frequently clay pipe at the end of its life. Connecting an Abodu to a lateral already near failure means backups and slow drains. We camera the line, replace or upsize what’s needed, and tie the unit in correctly.
- Drainage that pools at the unit’s base. Mid-century additions in Pomona often have low-slope roofs that dump water right where an Abodu pad goes. Factory plans don’t account for that. We re-grade and install swales or area drains so water moves away from the floor system.
- Factory roof and venting underperforming in Santa Ana heat loads. Pomona’s summer heat and fall wind events stress factory-spec roofing and venting. We see owners with heat gain inside the unit that shouldn’t be there. We upgrade venting and roof details to match what Pomona’s actual climate throws at it.
Abodu Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing most Abodu buyers don’t learn until permit review: Pomona’s 91766 and 91767 ZIPs hold the densest inventory of pre-1950 houses in the city, and a lot of those houses sit on original redwood sill plates and shallow 1920s concrete foundations. That’s not a fun fact, it’s a construction reality. Before we pour an Abodu pad behind one of these houses, the city routinely requires an engineer-specified foundation retrofit on the host house itself. The logic is simple: if the original house isn’t seismically adequate, adding a dwelling in the rear yard compounds the problem. Tract-built cities east of here never trigger this step because their housing stock is newer. Pomona does. We’ve done enough of these retrofits now that we can usually tell you within the first site visit whether you’re looking at a simple pad pour or a host-house retrofit that adds engineering time and cost. On a Wilton Heights lot off White Avenue, we set an Abodu One behind a 1920s Craftsman whose rear yard had never been graded flat and whose original sill plates sat on a shallow 1920s concrete foundation. We brought in an engineer for a foundation retrofit on the host house, re-poured a level pad on engineered fill, and upsized the electrical service and sewer lateral to carry the unit. The finished placement cleared Pomona’s building and safety inspections with the unit’s drainage tied into a new swale away from the low-slope back addition. That’s the difference between knowing Pomona and just delivering a prefab box.
Abodu Models & Products We Service in Pomona
We service the full Abodu line: the Abodu One, a one-bedroom 340 square foot backyard unit; the Abodu Two, a two-bedroom around 500 square feet; and the Abodu Studio, a single-room unit. For structural connections and weather-sealing details, we insist on Abodu’s OEM components because fit and warranty matter there. For panels, fixtures, and finish hardware, we use quality aftermarket parts where they meet or beat factory spec, and we’ll tell you when they don’t. If the shell and pad are sound, we repair and re-level rather than replace. We only recommend a new unit when the core structure or pad is beyond economical correction. We keep common Pomona-specific parts staged locally so we’re not waiting on factory lead times when your unit needs attention.

AfterAbodu Service Pricing in Pomona
What you’ll pay depends on what your lot and host house throw at us. A straight pad pour on a flat, modern lot costs less than a host-house retrofit plus sewer lateral replacement on a 1920s bungalow. Here’s what our Pomona work typically runs:

|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |
| Roof Replacement | $8,000 – $20,000 |
| Garage Conversion | $30,000 – $80,000 |
Every estimate is free and written line-item. We walk the lot, check the panel and lateral, and tell you what’s actually required versus what can wait. If you want a firm number before committing, call (877) 265-6284 and we’ll schedule the site visit.

FAQs – Abodu Construction in Pomona
If your house is pre-1950 and sits on a shallow 1920s or 1930s concrete foundation, there’s a high chance Pomona’s building department will require an engineer-specified retrofit on the host house before the unit gets permitted. We’ll tell you after the first site visit whether that’s likely on your lot. Call (877) 265-6284 to get us out there for a look.
Sometimes, but not often on older Pomona homes. Many 91766 and 91767 houses have clay laterals near end-of-life and panels that were maxed out decades ago. We camera the line and check the panel load before recommending anything. If an upsize is needed, that cost gets folded into the line-item estimate, never sprung later. Call (877) 265-6284 for a free assessment.
We re-grade the pad area and install a swale or area drain that moves water away from the unit’s base. Low-slope roofs on mid-century Pomona additions shed water poorly, and factory plans don’t account for that. This is standard practice on our Pomona jobs. Call (877) 265-6284 and we’ll walk the lot with you.
Yes. Infill lots in Pomona—and areas like Los Serranos Abodu service territory—often mean tighter setbacks, existing utilities in the way, and no room for error on grading. We handle the permitting and retrofit realities the factory’s standard install package doesn’t anticipate. The city reviews it like any other ADU, but Pomona’s older infrastructure makes the site work more involved. Call (877) 265-6284 and we’ll explain what your specific lot triggers.
We do. Factory-spec roofing and venting often underperform in Pomona’s heat and wind conditions. We upgrade venting, roof ties, and sometimes the roof assembly itself so the unit holds up to what the climate actually does here. When we replace roofs on Abodu units or the host house, the work ties into the same standards we’d use on a full home in Pomona. Call (877) 265-6284 for a roof assessment.
