Palmetto Bay full bathroom remodel permits — the key details

Lead-paint rules apply to Palmetto Bay homes built before 1978. If your bathroom has original painted trim, drywall, or shelving, and you're disturbing more than 10 square feet of paint per room (or any impact/renovation in a children's bedroom), you trigger the EPA's RRP (Renovation, Repair, and Painting) Rule. The contractor must be RRP-certified, use containment barriers, and provide a lead-hazard pamphlet to occupants. Many Palmetto Bay homeowners skip this cost ($500–$1,500) during bathroom remodels, only to discover during final inspection that the inspector requires RRP documentation or proof of lead-safe work practices. If you're hiring a general contractor, verify they are EPA-certified; if you're owner-building, you must be certified or hire an RRP contractor for any paint disturbance. The permit application does not always ask about lead paint outright, but the Building Department may flag it during intake if the home year is pre-1978. Adding this cost and timeline upfront (RRP work can add 1–2 weeks) prevents surprises at final inspection. Palmetto Bay has not adopted stricter lead rules than EPA baseline, but inspectors are thorough in enforcement.

Three Palmetto Bay bathroom remodel (full) scenarios

Palmetto Bay's exhaust-fan and moisture-control obsession

Palmetto Bay sits in Miami-Dade County's high-humidity, salt-spray coastal zone. The city's Building Department has learned through decades of mold claims and hurricane-driven moisture intrusion that exhaust fans and duct termination are non-negotiable. When you submit a bathroom remodel plan, the reviewer will scrutinize every detail: Is the duct properly sized (minimum 4 inches for fans over 100 CFM)? Does it have a damper? Is the damper corrosion-resistant (not aluminum)? Is the duct routed directly to exterior, or does it dump into attic/crawlspace (which causes mold)? Does the duct have insulation to prevent condensation buildup? If you're terminating through a soffit, has the damper been spec'd for salt-spray corrosion? Most rejections in plan review cite missing or vague exhaust details.

The IRC M1505.2 standard requires a minimum 0.5-inch clearance between the duct outlet and any wall, eave, or soffit; this prevents wind-driven rain from entering the duct when the damper closes. Palmetto Bay inspectors will measure this during final inspection. If your contractor routed the duct to a traditional aluminum louver vent (common in older installs), Palmetto Bay's salt-spray environment will corrode it in 3–5 years, and the damper will fail — a costly repeat repair. Specify a stainless-steel or plastic damper; the cost difference is $40–$100, and it saves thousands in water damage later. Additionally, if your bathroom exhaust duct crosses an unconditioned attic, it must be insulated with at least 1 inch of rigid insulation or wrapped with reflective insulation; this prevents condensation from dripping inside the duct and creating mold. This detail is often missed by DIY installers and flagged at final inspection.

Palmetto Bay has not adopted a local ordinance stricter than Florida Building Code, but inspectors apply the code with unusual rigor because the city's insurance claims database shows that poor exhaust ducting and moisture barriers are correlated with mold complaints and insurance denials. If your plan omits exhaust details, expect a single-sheet rejection note asking for manufacturer specs and installation photos. Many homeowners view this as bureaucratic delay; it is actually liability prevention. Budget an extra 1–2 weeks for plan resubmittal if your first submission lacks exhaust detail.

Waterproofing assemblies, Florida Building Code, and why Palmetto Bay inspectors care so much

Florida Building Code Section 702.4.2 (adopted by Palmetto Bay) specifies three approved waterproofing methods for shower and tub enclosures: cement board with approved waterproof membrane, prefabricated shower pan (as a complete waterproofing system), or tile backer board with integral water resistance. The key word is 'approved' — inspectors reject plans that say 'waterproof drywall' or 'tile backer' without specifying the product. You must name the product (e.g., 'Schluter-KERDI board' or 'Durock Cement Board with Redgard liquid membrane') and describe installation (slope, fastening, membrane overlap). This is not optional in Palmetto Bay; inspectors have seen enough water-damage claims from improper waterproofing that they demand certainty.

The cement board plus liquid membrane method is the most common and typically the lowest-cost option for tile showers. The process: install 1/4-inch cement board (not drywall) on walls and floor, slope the floor toward the drain at 1/4 inch per foot, apply a liquid waterproof membrane (Redgard, Aqua Defense, etc.) over the entire assembly with 6-inch overlaps at seams, let cure, then tile. Cost: $300–$600 in materials for a 5x8 bathroom. If you're using a prefabricated fiberglass shower pan, the entire pan is the waterproofing system; no additional membrane is needed, but the installation must be per manufacturer's specs (silicone sealing at seams, proper slope, etc.). Palmetto Bay's plan reviewer will ask for the pan manufacturer's installation guide — a one-page attachment to your permit application that takes 2 minutes to download but is frequently omitted.

Post-construction, Palmetto Bay inspectors will visually confirm the waterproofing method during rough plumbing inspection (before drywall or tile is installed) and again at final inspection. If you've installed cement board, the inspector will verify it's not standard drywall and that seams are taped and sealed. If you've used a shower pan, the inspector will check that the drain assembly is sealed and the pan is supported per code. Skipping or falsifying waterproofing documentation is a straight permit rejection; you cannot proceed until corrected. This is not Palmetto Bay being difficult — it's the city enforcing a rule that prevents $10,000+ mold remediation claims in high-humidity Florida.
