Abodu ADU Site Prep & Utilities in West Hollywood: What to Know First
We provide independent Abodu ADU site prep and utilities in West Hollywood, typically quoting foundation and utility packages within 48 hours of site visit and completing most single-trade jobs in 2-4 weeks once permits clear. Every project ships with a written price before any work starts, per Haven Standard Clause 1, plus a documented photo record of existing conditions and completed work. This page is for Abodu owners who have received their unit specifications and now need the site made ready: foundation and grading, electrical panel capacity, plumbing laterals, gas line extension, and the hardscape that ties it to the main house. If you’re comparing estimates already in hand, we offer a Free Second Opinion. Call (213) 329-7167 to schedule your site evaluation.
How Abodu Products Fail - and How We Fix Them
- Abodu One foundation misalignment on sloped West Hollywood lots. The One’s steel chassis is engineered for a 3/8-inch-per-foot maximum grade tolerance, but hillside parcels above Sunset Plaza and north of Santa Monica Boulevard often present 6-8 inches of fall across a 20-foot pad. We laser-grade to spec, then pour a stem-wall foundation with engineered fill rather than trying to shim the chassis, which voids the structural warranty.
- Abodu Two electrical panel back-feed conflicts. The Two’s 200-amp service requirement frequently collides with original 100-amp panels in 1920s-1950s West Hollywood duplexes and courtyard apartments. We spec a load calculation per NEC 220.82, upgrade to 400-amp dual-lug service where needed, and coordinate with LADWP on meter location so the Abodu doesn’t brown out the main unit during summer AC peaks.
- Abodu Studio plumbing lateral root intrusion on older streets. Clay sewer laterals in the Norma Triangle and West Hollywood West neighborhoods, some dating to the 1940s, crack under the compaction load of a new foundation. We camera the line before pad prep, spot-repair with trenchless epoxy liner or full replacement to city tap, and document the video for the permit closeout.
- Abodu One gas line extension pressure drop in multi-unit lots. The One’s tankless water heater and cooktop draw 199K BTU combined; existing 1-inch gas runs in fourplex conversions can’t sustain pressure at that load. We size new polyethylene trunk lines to the meter, pull a pressure test witnessed by the city inspector, and tag the line with BTU capacity so future owners know the margin.
- Abodu Two hardscape drainage pooling against stucco cladding. The Two’s lower profile sits closer to finished grade than site-built ADUs. Without a 6-inch minimum clearance and a sloped concrete or paver apron, irrigation back-spray and winter sheet flow wick into the rainscreen. We detail a perimeter drain tied to the site’s existing drainage plan, with weep screed visible for inspection.
Our Abodu ADU Site Prep & Utilities Process
- 1
Site evaluation and scope lock. We walk the lot with the Abodu spec sheet, shoot grades, locate utilities, and photograph every existing condition. You receive a written price and a permit timeline before we produce drawings.
- 2
Permit set as core product. Our drafting team produces the site plan, utility plan, and structural details for West Hollywood Building & Safety. The permit set is the product; construction follows from approved drawings, not the other way around.
- 3
Foundation and rough utility prep. Excavation, compaction testing, steel or concrete pour, and simultaneous trenching for electrical, plumbing, and gas. Every phase is photographed and uploaded to your project folder.
- 4
Utility connection and fixture set. Panel upgrade, lateral tie-in, gas pressure test, and meter coordination with LADWP and SoCalGas. We use OEM Abodu connection kits where specified, or engineer equivalent where the OEM part is back-ordered.
- 5
Final inspection and documentation. City inspector signs off; we deliver the photo record, as-builts, and the 365-Day Done Right Promise in writing. The document is the promise. Everything else is a conversation.
- 6
Hardscape and landscape tie-in. Concrete apron, pavers, or decomposed granite per the site plan, with drainage verified under flow test before we sign the final punch list.

Why West Hollywood Homeowners Call Ellery ADU Studio West Hollywood for Abodu Work
We’ve specified and coordinated Abodu, Cover, and Dvele systems since the prefab ADU category emerged in California, and we’ve learned that the unit is only half the project - the site is where most delays and cost overruns hide. Our 365-Day Done Right Promise covers the foundation and utility work, not just the box that sits on it. Nadia Ellery grew up watching permit drawings mismatch finished walls; she built Ellery ADU Studio so that doesn’t happen on our sites. Every crew is background-checked and uniformed, license numbers appear on every page, and a live person answers calls 24/7. If you already have an estimate in hand, we’ll give you a Free Second Opinion with line-item comparisons.
FAQs
No - Abodu’s structural warranty covers manufacturing defects, and our foundation and utility work is documented separately for your records. We coordinate with Abodu’s install team where the scopes touch, and we warranty our own work under the 365-Day Done Right Promise. For warranty questions specific to your unit, call us at (213) 329-7167 and we’ll walk through the documentation you’ll need.
Most single-trade utility jobs take 2-4 weeks after permit approval; full foundation and utility packages run 6-10 weeks. West Hollywood Building & Safety typically reviews ADU site plans in 4-6 weeks, faster if the project qualifies for SB 9 ministerial approval. Call (213) 329-7167 for a timeline based on your specific lot and Abodu model.
Replace if the lateral or service line is original clay, cast iron, or galvanized steel - common in West Hollywood pre-1960s stock. We camera every line during site evaluation and show you the footage before you decide. Repair makes sense for isolated root intrusion or single-point cracks; replacement is the better long-term asset play for aged infrastructure. Call (213) 329-7167 to schedule the camera inspection.
We use Abodu OEM connection kits where the spec requires them and where lead times allow. For back-ordered OEM items, we engineer equivalent fittings with documented equivalency letters so your permit inspection passes clean. We never substitute without writing it into the scope and showing you the spec sheet. Call (213) 329-7167 to discuss parts sourcing for your specific Abodu line.
Under Haven Standard Clause 5 (No Surprises), the scope is locked at signing. If we encounter concealed conditions - a buried oil tank, an unmapped sewer line - we photograph it, stop work, and present a written change order with options before proceeding. You are never billed for a surprise. Call (213) 329-7167 to review the change-order protocol before your project starts.
