Cover ADU Site Prep & Utilities Nationwide

Cover ADU Site Prep & Utilities in Van Nuys: What to Know First

We provide independent Cover ADU site prep and utilities work in Van Nuys, typically from initial site assessment through final utility hookup in 6-10 weeks depending on LADBS permit timing. Every project carries a written price before work starts, per Haven Standard Clause 1, and our 365-Day Done Right Promise applies to every Cover foundation, electrical, plumbing, and gas line we install. This page is for Van Nuys homeowners who have purchased or are considering a Cover unit and need the site infrastructure handled by a team that knows how Cover’s modular systems interface with local soils, slopes, and utility requirements.

How Cover Products Fail - and How We Fix Them

• Foundation misalignment on the Cover Backyard series. The Backyard’s steel frame chassis tolerances are tight, and Van Nuys’ expansive clay soils in the Sepulveda Basin area shift seasonally. We’ve seen three Backyard units in the 91406 zip develop hairline foundation cracks where the standard 12-inch footing depth met reactive soil. Our fix: we order a soils report before breaking ground, then specify either a post-tensioned slab or helical piers if the expansion index exceeds 30, documented in the permit set.
• Electrical panel overload on Cover Studio units with EV charging. The Studio’s base 100-amp service package assumes standard residential load, but Van Nuys homeowners adding EV chargers and the ADU simultaneously frequently trip the main. We upgrade to 200-amp service with a load calculation stamped by our electrical engineer, submitted as part of the single permit package.
• Plumbing lateral root intrusion near mature ficus trees. Van Nuys’ 1950s-1970s housing stock often has original clay sewer laterals running through root zones. Cover’s spec calls for a 4-inch ABS connection, but we’ve found roots collapsed the host home’s lateral before the ADU tie-in. Our fix: we camera the full line during site prep, price trenchless pipe bursting if needed, and never bury a new connection over a failing host line.
• Gas line pressure drop on Cover Pool House units with pool heaters. The Pool House shares a gas meter with the main residence in most Van Nuys configurations, and the combined BTU load of pool heater plus ADU appliances exceeds 1.25 CFH on older 1-inch lines. We upsize to 1.25-inch or run a dedicated second meter per SoCalGas requirements, pulled into the same permit set.
• Hardscape drainage backflow into Cover unit crawl spaces. Van Nuys’ flat lots and occasional winter sheet flooding mean water finds the lowest point. Cover’s standard 6-inch stem wall isn’t always sufficient where grade was altered decades ago. We install perimeter French drains tied to city storm where available, with elevation certificates proving positive drainage before final inspection.

Our Cover ADU Site Prep & Utilities Process

1. 1
   Site survey and soils assessment. We walk the Van Nuys property with the Cover unit’s spec sheet, flagging utility routes, slope, and any mature trees within 15 feet of the planned foundation. If the lot is in the Sepulveda Basin clay zone, we order a soils report before pricing.
2. 2
   Utility capacity verification. We pull SoCalGas and LADWP records to confirm service size, then engineer the electrical load calculation and plumbing/gas sizing to match the Cover model’s requirements plus your actual usage.
3. 3
   Permit set preparation. Our in-house drafters produce the full LADBS submittal: foundation plan, MEP riser diagrams, and Title 24 energy compliance. One contract, one price, one set of drawings. No designer-builder gap.
4. 4
   Construction and documented photo record. Our background-checked, uniformed crews execute the site prep and utility work. Every visit generates dated photos, uploaded to your project folder. You see what we found, not what we felt about it.
5. 5
   Utility activation and final inspection. We coordinate SoCalGas meter set, LADWP service release, and sewer lateral inspection. The Cover unit’s crane-set or flatbed delivery is scheduled only after utilities are live and inspected.
6. 6
   365-Day Done Right Promise activation. Your written warranty begins at final sign-off. If the foundation, electrical, plumbing, or gas work doesn’t match the permitted drawings, we make it right. The document either says it or it doesn’t - let’s look at the document.
