Why Groundwork Construction Co. of South Florida Is West Gate’s Preferred Home Additions & ADU Company
We’ve built a reputation in West Gate by showing up prepared for what this specific community demands. Homeowners here aren’t dealing with a city building department - they’re navigating Palm Beach County’s processes, and we’ve learned those rhythms through repeated projects in the 33409 ZIP.
Our response time to West Gate is typically same-day or next-day for consultations. We’re not guessing about your property’s zoning or setback rules. We’ve worked with the county’s plans examiners enough to know how ADU applications move through their queue, and we know which details trigger questions before they become delays.
Raymond Estevez has directed our team through multiple West Gate additions where the real work started with understanding what the county would require, not just what the homeowner wanted to build. That preparation shows up in fewer surprises and faster approvals.
Our Home Additions & ADU Services in West Gate
ADU Design & Permitting
Every ADU in West Gate starts with Palm Beach County zoning, not city rules. The county’s setback requirements for accessory structures differ from what you’d face in incorporated West Palm Beach, and we’ve seen out-of-area contractors submit plans that get rejected because they assumed municipal standards applied. Our Home Additions & ADU team handles the full design-permit-build sequence, including county-specific documentation for wind-load calculations and impact-rated opening schedules. We recently added a 400-square-foot ADU behind a CBS home on 49th Court, and during the demolition we found the original roof lacked hurricane straps. Before the county would issue the permit, we had to retrofit the existing structure with code-compliant tie-downs, install impact-rated windows from our approved line, and moisture-barrier the slab - extra work that saved the homeowner from a costly post-storm failure.
Garage Conversion ADU
Garage conversions in West Gate run $30,000-$80,000 and represent one of the faster paths to rental income or multigenerational housing, but they come with county-specific complications. Palm Beach County treats garage conversions as change-of-use projects requiring full permitting, not simple renovations. The existing slab often needs moisture remediation because of the area’s high water table, and any new living space must meet current Florida Building Code wind-load standards. We evaluate whether your garage structure can support the conversion without extensive reinforcement, and we flag early when the county will require engineered drawings for structural modifications.
New Detached ADU
A new detached ADU in West Gate gives you maximum flexibility for rental income or family use, but it’s also the most permit-intensive option under county jurisdiction. Setback rules from property lines, utility easements, and existing structures all fall under Palm Beach County’s unincorporated zoning code. We handle site evaluation, utility routing, and the full construction package, with options ranging from traditional stick-built to prefab units from Mighty Buildings or Plant Prefab for faster timelines. Every new ADU we build in West Gate includes impact-rated openings and proper slab moisture barriers as standard, not upgrades.
Junior ADU & Interior Conversion
For homeowners who want additional living space without separate structure permits, junior ADUs and interior conversions offer a streamlined path. These projects still trigger county permit requirements for electrical, plumbing, and egress changes, and they often reveal the same code deficiencies we find in full additions: non-compliant electrical panels, inadequate structural connections, or original windows that don’t meet current wind-load standards. We assess these factors upfront so your interior conversion doesn’t stall mid-project when the inspector finds issues.

Common Home Additions & ADU Problems We See in West Gate Homes
- Missing hurricane straps on pre-Andrew CBS homes. Most houses in West Gate’s 33409 ZIP were built between the 1960s and 1980s, before Florida’s post-Hurricane Andrew building code overhaul. We regularly find roof-to-wall connections that fail current standards, and Palm Beach County won’t approve new permits until these are retrofitted.
- Assuming West Palm Beach zoning applies. Because West Gate is unincorporated, county setback and ADU rules control - not city rules. Contractors who file plans based on municipal standards waste weeks getting rejected and resubmitted.
- Inadequate moisture barriers on slab work. The high water table in Palm Beach County, often just feet below grade, makes slab preparation critical. We’ve torn out additions where improper barriers led to persistent dampness and foundation deterioration.
- Non-impact-rated openings in new construction. The Florida Building Code enforces strict wind-load requirements in this coastal county. Using standard windows or doors in new ADU openings guarantees permit rejection and potential structural vulnerability.

FAQs - Home Additions & ADU in West Gate
West Gate is unincorporated, so Palm Beach County Building Division handles all permits and inspections rather than a city department with its own streamlined processes. County plans examiners serve a larger geographic area with varying zoning categories, which typically extends review timelines compared to West Palm Beach’s municipal system. We build extra lead time into our West Gate project schedules and pre-submit documentation to minimize delays. Call (844) 665-0162 and we’ll walk you through current county processing times.
Yes, Palm Beach County requires that existing structures meet current Florida Building Code wind-load standards before they’ll approve permits for new attached work. For 1970s-era CBS homes in West Gate, this almost always means retrofitting hurricane straps or other approved tie-downs at roof-to-wall connections. We identify these requirements during our initial structural assessment and include the retrofit scope in your estimate. Call (844) 665-0162 for a free evaluation of your specific property.
Detached ADU setbacks in West Gate follow Palm Beach County’s unincorporated zoning code, which differs from incorporated city rules. Specific requirements depend on your property’s zoning designation and lot dimensions, but county rules typically require greater side and rear setbacks than West Palm Beach allows for similar structures. We verify your parcel’s exact zoning and setback requirements before designing, preventing plan rejection. Call (844) 665-0162 and we’ll pull your property’s county records.
West Gate’s location in Palm Beach County means a consistently high water table, often within a few feet of grade, which makes proper moisture barriers and soil compaction essential for any slab work. County inspectors are familiar with local failure modes and scrutinize subgrade preparation closely. We engineer our slab specifications for these conditions as standard practice, not as an optional upgrade. Call (844) 665-0162 to discuss how we handle site prep for your specific lot.
No, garage conversions in unincorporated West Gate require full Palm Beach County permits for change of use, electrical, plumbing, and structural modifications. Unpermitted work frequently gets flagged during later property transactions or when homeowners apply for additional permits, triggering costly retrofits and potential penalties. We handle the complete permitted conversion process from application to final inspection. Call (844) 665-0162 for a compliant, documented garage conversion estimate.
