How Cover Products Fail - and How We Fix Them

• Foundation settlement on Cover’s lighter-weight modules. Cover’s engineered floor systems, particularly in the Cover Backyard line, distribute load differently than conventional slab-on-grade construction. In Santa Ana’s clay-heavy soils, especially near the Santiago Creek wash, we’ve seen modules develop corner sag when the gravel bed beneath was compacted to residential rather than modular spec. We regrade with 6-inch crushed aggregate, plate-compacted in lifts, and document the density test.
• Electrical service mismatch with Cover’s integrated panel. Cover units ship with a pre-wired 200-amp main panel, but Santa Ana homes built before 1985 often carry 100-amp services with full breaker slots. The Backyard Studio series in particular expects a dedicated 125-amp minimum feeder. We upgrade the service, coordinate with SCE on the lateral size, and handle the city electrical permit as part of our single contract.
• Plumbing lateral slope issues on sloped lots. Cover’s wet modules, including the Cover Bathroom and Kitchen configurations, specify a 2% gravity drain slope. On the hillside lots above Centennial Regional Park, we’ve found original sewer laterals at 1% or less. We expose the full run, laser-level the replacement, and pull the plumbing permit ourselves rather than handing off to a subcontractor.
• Gas line capacity on older Santa Ana mains. Cover’s kitchen modules with tankless water heaters demand higher BTU input than the original gas sizing assumed. In the historic districts near French Park, 1-inch mains at low pressure won’t deliver. We pressure-test the existing line, size the extension correctly, and coordinate with SoCalGas on the meter upgrade.
• Hardscape drainage pooling against module thresholds. Cover’s door systems sit lower to the finished grade than site-built ADUs for accessibility compliance. In Santa Ana’s brief but intense winter rains, poorly sloped pavers send water toward the weatherstrip. We redesign the hardscape pitch, install channel drains where needed, and specify permeable joints for the landing area.

Our Cover ADU Site Prep & Utilities Process

1. 1
   Site evaluation with documented photo record. We walk the property with the Cover placement drawings, photograph existing utilities, soil conditions, and access constraints. You receive these images same day.
2. 2
   Utility capacity verification. We confirm actual available amperage, gas pressure at the meter, and sewer lateral depth with the respective utilities, not assumptions from satellite maps.
3. 3
   Written scope and price. Under Haven Standard Clause 1, we deliver a line-item quote: foundation prep, electrical upgrade, plumbing lateral, gas extension, and hardscape. No call-for-pricing. No allowances.
4. 4
   Permit pull as single-point responsibility. Because we’re design-build, the same team that drew the utility plan submits to Santa Ana Building & Safety and responds to corrections.
5. 5
   Construction with progress documentation. Every visit produces dated photos of trench depth, conduit runs, compaction tests, and final connections. These go in your project folder, not our memory.
6. 6
   Utility activation and final inspection. We coordinate SCE, SoCalGas, and city inspectors for a single sign-off. The 365-Day Done Right Promise begins at passing inspection.
