Jerith Home Additions & ADU: The West Palm Beach Owner’s Guide
Most Jerith home additions and ADU structures in West Palm Beach fail at the connection points, not the frame itself: the tie-downs, the hurricane strapping, and the flashing where the addition meets the original structure. A full Jerith addition or ADU project in West Palm Beach runs $45,000 to $130,000 depending on square footage, foundation type, and whether you’re building out or up. We inspect and repair Jerith-built additions and ADUs, and we build new ones sized and strapped for Florida wind code.
What owners usually notice first is a door that won’t latch cleanly, a hairline crack running along a ceiling seam, or daylight showing through a corner joint. That’s the structure moving. In West Palm Beach, with our sandy soil and seasonal saturation, movement shows up faster than most manufacturers account for.
Which Jerith Models This Applies To
Jerith’s residential addition and ADU line falls into two broad groups. The first is site-built additions framed in place to match the original house, typically using Jerith’s standard 2×6 wall assemblies and manufactured roof trusses. The second is their panelized ADU series, which arrives as pre-fabricated wall and roof sections that get assembled and tied down on a slab or pier foundation.
The compatibility gotcha is in the tie-down system. Older Jerith additions, especially those built before Florida updated its high-velocity hurricane zone requirements, used lighter-gauge straps than what current code requires. If you have a Jerith structure from before roughly 2015, the strapping may not meet today’s wind-load requirements, even though the structure itself is sound. We check the strapping on every Jerith project we touch, because that’s the difference between an addition that holds and one that doesn’t.
For OEM versus aftermarket: on trim, flashing, and fasteners, quality aftermarket equivalents are fine. On structural connectors and tie-downs, we specify the exact or upgraded equivalent, never a generic substitution. If the part carries a load, it gets matched or exceeded.
Bradford Remodeling Co West Palm Beach is an independent service provider. We are not affiliated with Jerith, but we work on their structures regularly and source parts that meet or exceed the original specifications.

Signs Your Jerith Home Additions & ADU Is Failing
- Doors and windows that stick or won’t latch. This usually means the frame has settled unevenly. In West Palm Beach, the culprit is typically foundation movement from our sandy, shifting soil rather than a framing defect. The fix starts with checking the foundation, not adjusting the door.
- Diagonal cracks at the corners of windows and doors. These are stress cracks from racking, often tied to inadequate shear wall or failing hurricane strapping. In a Jerith addition, this is a structural signal, not a cosmetic one.
- Separation where the addition meets the original house. A visible gap at the seam, even a quarter inch, tells you the two structures are moving independently. That seam is where water and pests get in, and in Florida humidity, it doesn’t take long for mold to follow.
- Soft spots in the floor or a spongy feel under foot. On a Jerith addition built over a crawl space or pier foundation, this points to moisture damage and compromised subflooring. In West Palm Beach’s wet season, a small flashing or vapor barrier failure becomes a big repair in a single summer.
- Rusted or corroded straps and connectors visible in the attic or crawl space. Salt air and humidity eat metal faster here than in most of the country. If the tie-downs and hurricane straps are corroding, the structure is no longer doing what the wind code requires of it.

AfterReplacement Cost & What’s Included
A new Jerith-style home addition in West Palm Beach runs $45,000 to $130,000 installed. An ADU construction project runs $90,000 to $220,000. A garage conversion falls between $30,000 and $80,000. The range comes down to size, foundation work, roof complexity, and how much of the existing structure needs to be brought up to current hurricane code.
We give you a written price before any work starts. That price covers the full scope: demolition where required, framing, electrical and plumbing rough-in, drywall, trim, paint, and the written guarantee. If the site reveals something the plan didn’t cover, Curtis Lane calls you before we touch it, and you get a new number in writing. Nobody changes a price at the door.
Every project we complete carries the 365-Day Done Right Promise. If the work fails within one year of completion, we return and correct it at no charge. That’s in writing, signed, in your hand at close, before we leave the site.
DIY or Call Us?
You can safely check a few things yourself. Walk the seam where your Jerith addition meets the house and look for daylight or gaps. Check the doors and windows for latching issues. Look for visible rust on any exposed metal connectors in your attic or crawl space. Document what you find and call us.
What you should not do is start pulling trim, opening walls, or attempting to re-level a settled structure. Home additions and ADUs carry roof loads, and in West Palm Beach, every connection point is doing wind-load work. If you open up a bearing wall without proper shoring, you’re gambling with the roof over your head. This is not a job for a Saturday and a reciprocating saw. Call (728) 203-9809 and get a straight answer from someone who does this work in West Palm Beach every week.
FAQs
A properly built home addition should last 50-plus years, but in West Palm Beach’s humidity, salt air, and sandy soil, the metal connectors and flashing are the weak points and many fail within 20 to 30 years if they weren’t upgraded. The frame itself rarely fails first. Call (728) 203-9809 and we’ll inspect the connectors and strapping before you spend money on anything else.
Yes, in most cases a failing addition can be repaired, and that’s usually the right call when the foundation is sound and the failure is in the connectors, flashing, or localized framing. If the framing is rotted or the foundation has shifted significantly, targeted replacement is more cost-effective than repeated repairs. The only way to know is an on-site look, and the estimate is free.
Most home additions take 3 to 6 months from permit to final inspection, and ADU construction typically runs 4 to 8 months. West Palm Beach permitting and inspection timelines, plus our hurricane-season weather windows, are the variables that move the schedule. We put the timeline in the written scope so you know what done looks like before we start. Call (728) 203-9809 for a project-specific schedule.
We keep common structural connectors, hurricane strapping, flashing, and fasteners on the truck because those are the parts that fail on Jerith additions and ADUs in this climate. For larger components like trusses or panelized wall sections, we order to spec with a lead time built into the written schedule. We also work with other premium brand materials, including KraftMaid cabinetry, Cambria and Silestone surfaces, so completed additions finish to a documented standard.
