Cover Home Additions & ADU: The Pompano Beach Owner’s Guide

Cover home additions and ADU construction in Pompano Beach typically runs $45,000-$130,000 for a standard addition and $90,000-$220,000 for a detached ADU, with Rowan Construction Group stocking compatible framing systems, hardware kits, and structural connectors for Cover-designed projects. Most owners first realize something’s wrong when permits get rejected for non-compliant connection details, or when the existing addition shows settlement cracks where the Cover-specified ledger attachment was substituted with generic hardware. In Pompano Beach’s coastal zone, with salt air and the seasonal saturation cycles that come with it, we’ve seen Cover-compatible LVL beams and hurricane-rated connectors fail prematurely when the original installer didn’t account for the 170 mph wind-load requirement in Broward County’s HVHZ.

Which Cover Models This Applies To

Cover’s home addition and ADU system isn’t sold by traditional model year, but by structural package and connection type. The two identifiers you need are the beam specification tag (usually stamped on the LVL end or a metal tag on the ledger) and the hardware schedule from your original Cover documentation. Look for “CVR-L” series ledger connectors, “CVR-B” beam hangers, or the newer “CVR-HV” hurricane-rated set designed for South Florida.

The OEM Cover hardware is galvanized to G185 specification, which matters in Pompano Beach because standard G90 hardware corrodes faster within five miles of salt water. We stock both genuine Cover replacement connectors and Simpson Strong-Tie equivalents that meet or exceed the same spec, at a lower unit cost. The catch: Simpson’s HGAM series fits the CVR-L profile but requires a different fastener pattern. We’ve had owners in Harbor Village bring us boxes of mismatched hardware because the online listing showed “compatible” without noting the ⅜” vs. 7/16″ bolt spacing difference. Check the stamp. Measure twice, say it once, show your work.

Signs Your Cover Home Additions & ADU Is Failing

• Settlement cracks running diagonally from addition corners. This usually means the Cover-specified helical pier or footing wasn’t installed to the engineered depth, and the addition is settling independently of the main structure. In Pompano Beach’s sandy soils near the Intracoastal, we’ve seen piers stop at 8 feet when the geotech called for 14.
• Ledger board pulling away from the main house with visible gap at the top. The through-bolts or lag screws have corroded or were undersized from the start. Cover’s system calls for ½” diameter hot-dip galvanized bolts on 16″ centers; anything less, and the cantilever load from the addition works the fasteners loose over time.
• Floor bounce or visible sag in the addition’s center span. The LVL beam may be the wrong depth for the span, or the original builder substituted a lower-grade lumber without updating the engineering. Cover’s tables are explicit: a 16-foot span needs a minimum 11⅞” LVL in their system.
• Water intrusion at the addition-to-house junction after any storm. The Cover-specified flashing detail was skipped or replaced with caulk. In Pompano Beach, with driving rain from the southeast, this junction is the highest-leak-risk point on any addition. The Z-flashing and membrane overlap are not optional.
• Doors and windows in the addition that bind or won’t latch seasonally. This indicates differential movement between the addition and main structure, often from inadequate expansion detail in the Cover connection or frost-heave where the footing depth was insufficient. Even in Florida, soil moisture swings move structures.

Replacement Cost & What’s Included

Home addition and ADU work in Pompano Beach falls in our $45,000-$130,000 range for attached additions and $90,000-$220,000 for detached ADUs. What moves you within that range: square footage, whether we’re matching existing rooflines or building a separate structure, and how much of the existing failed work needs demolition versus correction in place.

Our written quote breaks out permits, demolition, structural materials, finishes, and labor as separate line items. Under Clause 1 of the Haven Standard, that price is fixed before any work starts. No change proceeds without a signed change order. Across 4,000-plus projects since 2007, this discipline has kept final invoices within a few percent of the original number. The 365-Day Done Right Promise covers the work, and you receive a documented photo record of every visit, included as standard.

DIY or Call Us?

There’s a short list of what a homeowner can safely verify: read the hardware stamp, measure bolt spacing, photograph cracks for comparison over time. What you should not attempt: jacking a settled beam, removing and replacing structural connectors, or modifying anything that carries live load. These are engineered connections, and in Broward County’s High Velocity Hurricane Zone, the inspector will flag non-compliant work that can cost more to correct than to have done properly the first time.

We’ve been called to jobs in Pompano Beach’s older neighborhoods where a well-intentioned owner replaced a corroded ledger with pressure-treated lumber not rated for ground contact, or used stainless fasteners that were the wrong grade for the galvanic reaction with the existing steel hangers. The fix cost double. If you’re unsure what you’re looking at, call (754) 714-6540 and we’ll schedule a free estimate. Grant Rowan or one of our crew will read the stamps, check the spans, and give you a written price before any work starts.
