Cover ADU Site Prep & Utilities Nationwide

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

We provide independent Cover ADU site prep and utilities in Burbank, with most foundation, electrical, and utility jobs quoted within 48 hours and scheduled within two weeks of permit clearance. Typical Cover site prep runs $18,000-$42,000 all-in, depending on whether we’re grading a sloped lot in the Verdugo Mountains foothills or extending a 100-amp electrical panel in Magnolia Park. The number goes on paper first. Everything else follows from that. This page is for Burbank homeowners who’ve chosen a Cover unit and need the ground, power, water, and gas handled by a team that knows how Cover’s foundation specs differ from stick-built requirements.

How Cover Products Fail - and How We Fix Them

• Foundation misalignment on Cover’s Backyard Studio series. The steel frame tolerances are tighter than conventional framing, and Burbank’s expansive clay soils in the foothill zones shift more than coastal substrates. We’ve seen three Backyard Studios in the Glenoaks area where the pier spacing was correct per Cover’s manual but the soil prep was insufficient for local conditions. We spec a geotechnical report for any Burbank lot above the 800-foot contour, then adjust pier depth and add helical tie-downs where the soil report demands it.
• Electrical panel undersizing on Cover’s Accessory Dwelling Unit line. Cover’s load calculations assume a 200-amp main, but Burbank’s pre-1980s housing stock, especially in the Rancho neighborhood, often runs 100-amp panels with no spare breaker space. The symptom is a permit hold at plan check when the load calc shows 187 amps on a 100-amp service. We catch this during our pre-permit site walk, coordinate with Burbank Water and Power for a service upgrade, and spec the panel in our single contract so the electrician and the prefab coordinator aren’t pointing at each other later.
• Plumbing lateral slope failures on Cover’s two-bedroom units. Cover’s wet wall stack location is fixed at 48 inches from the rear wall on the 640-square-foot model. In Burbank’s older flat lots near the airport, the existing sewer lateral runs shallow and at the wrong angle to meet that stack without a pump. The real cause is usually a 1950s clay line that settled after the Northridge quake. We camera the line, document the slope with a photo record, and price the grinder pump or the line replacement in the written scope before permit submission.
• Gas line pressure drop on Cover units with tankless water heaters. Cover specs a Rinnai or equivalent tankless, which needs 199,000 BTU at full fire. The half-inch steel service common in Burbank’s 1,200-square-foot original homes can’t deliver that at 30 feet of run. We pressure-test the existing line, calculate the pressure drop per Burbank’s amended CPC tables, and upsize to 3/4-inch CSST or run a dedicated line from the meter, depending on what the math says. No guessing. The calculation goes in the permit set.
• Hardscape drainage conflict on Cover’s units with integrated decks. Cover’s spec deck height is 18 inches above finish grade, but Burbank’s municipal code requires a 6-inch reveal between siding and hardscape to prevent termite access. In the Hillside District, we’ve seen two jobs where the integrated deck would have buried the weep screed. We redesign the transition with a stepped retaining wall and a French drain to daylight, documented in the site plan so Cover’s install team has clear grades to work from.

Our Cover ADU Site Prep & Utilities Process

1. 1
   Site walk and utility locate. We mark underground utilities through USA North 811, then walk the lot with a copy of Cover’s foundation plan and our checklist. Nadia Ellery or our lead site supervisor documents existing conditions with photos, which you receive same day.
2. 2
   Diagnostics and load calculations. We test electrical panel capacity, camera sewer laterals, and pressure-test gas lines. For Cover units, we verify the foundation spec against the actual soil conditions, not the generic manual.
3. 3
   Parts and materials decision. We use Cover-specified materials where the warranty requires it, and quality equivalents where it doesn’t. For example, we use Cover’s specified Simpson Strong-Tie hardware for the steel frame connection but may spec a local-equivalent rebar grade if the geotech report calls for higher tensile strength.
4. 4
   Permit set and written price. Our drafters produce the site plan, utility plan, and structural details as a single permit set. Under Haven Standard Clause 1, you receive one written price covering design, permitting, and construction. No call-for-pricing. No allowances that balloon later.
5. 5
   Construction and documentation. Our crews work to the permitted drawings, with a documented photo record on every visit. We coordinate directly with Cover’s install team so their crane date doesn’t conflict with our final utility hookups.
6. 6
   Final test and warranty. We pressure-test, megger-test, and flow-test every system. The 365-Day Done Right Promise begins at final inspection. If it’s not built to the permitted drawings, we make it right, in writing.
