Do I need a permit for a hurricane retrofit in
Casselberry, FL?

Casselberry hurricane retrofit permits — the key details

Florida law requires a building permit for any structural upgrade that improves a home's resistance to wind loads. This includes roof-deck attachment (nailing or screwing shingles and underlayment to the decking via FBC R905 standards), secondary water barrier installation (self-adhering peel-and-stick membrane under the shingle starter course), installation of hurricane shutters (whether metal, accordion, or roll-down, per FBC R301.2.1.1 HVHZ requirements), impact-rated windows and doors (TAS 201 or 202 certified), garage-door bracing or reinforcement (to withstand design wind speeds per FBC R301.2.1.1), and roof-to-wall connection upgrades (installing hurricane straps, clips, or engineered fastening at every truss or rafter bearing). The Casselberry Building Department treats these as minor structural work and does not require stamped engineering drawings if the retrofit meets prescriptive FBC standards — meaning a manufacturer's installation guide plus HVHZ certification label is usually enough. However, if your retrofit involves non-standard materials, a roof slope greater than 12:12, or a home built before 2002, the city may request a structural engineer's letter verifying that the design wind speed (115 mph for Seminole County per ASCE 7-22) is satisfied.

Casselberry's most common permit rejection is missing HVHZ labeling on shutters and impact windows. The city will not stamp off a permit if your shutter specification says 'aluminum hurricane shutters' without proof that those shutters have passed TAS 201 impact testing (for non-Miami-Dade installations) or TAS 202 (Miami-Dade and Broward protocol). If you buy shutters from a big-box store and they don't come with a TAS 201 cert, the city will reject the permit and you'll have to buy different shutters or get the manufacturer to supply the test report (which many do, but it takes 1–2 weeks). The same applies to impact windows: the window must carry a TAS 201, TAS 202, or NFRC rating proving impact resistance at 115 mph. Many contractors buy 'impact-ready' windows from a national supplier and assume they're code-compliant for Florida; they're not, unless the window spec includes the HVHZ label. Roof-to-wall straps are the second-most common rejection: the city requires that you specify the strap at EVERY truss-to-wall and rafter-to-wall connection, not just a few key points. If your retrofit plan shows straps at only the perimeter, Casselberry will ask for clarification or rejection. The remedy is simple (add more straps), but it delays approval by 3–5 days.

Exempt work does not exist for hurricane retrofits in Casselberry — even a single shutter or one set of hurricane ties requires a permit. However, routine maintenance that does not change the structural strength of the connection does not need permitting; for example, replacing a roof shingle because it's damaged does not need a permit, but installing secondary water barrier under the new shingle course does. The line is whether the work 'improves the structural integrity or wind resistance of the home.' If it does, you need a permit. Owner-builders are allowed to pull permits for their own home under Florida Statutes § 489.103(7), but they still must hire a licensed inspector to pull the OIR-B1-1802 insurance-discount form — owner-builders cannot sign that form themselves. This is a common misconception: many homeowners think 'I can do this myself and skip the permit.' Florida law says you can do the work yourself and pull the permit yourself, but you cannot sign the insurance-discount inspection form without a state-licensed wind-mitigation inspector credential. That credential is separate from a general contractor's license and requires 40+ hours of training and a passing exam.

Casselberry's permit review timeline is typically 1–2 business days for minor retrofits (shutters, impact windows, garage-door bracing) and 5–7 business days if the city engineer needs to verify compliance with roof-to-wall attachment standards. The city does NOT require 3D CAD plans or detailed spec sheets; a one-page form from the contractor (name, scope, HVHZ product label, design wind speed confirmation) is usually sufficient. However, you must submit the permit application (Casselberry Form CD-1 or equivalent, available on the city website) in person or via email to the Building Department. As of 2024, Casselberry does not have a fully online permit portal; you must contact the City of Casselberry Building Department directly by phone or in-person visit to submit and track your application. This differs from nearby cities like Winter Park or Orlando, which have online portals and e-permitting capability. The lack of an online portal means you should expect 1–2 phone calls or visits to confirm submittal, answer follow-up questions, and schedule inspections. Once approved, the city will issue a permit number (valid for 180 days) and you can schedule the in-progress inspection (usually after the secondary water barrier and roof-to-wall straps are installed but before the final shingle course is laid) and final inspection (after all work is complete and the home is waterproofed and structurally complete). Total construction time is typically 2–4 weeks for a full-home retrofit (roof, shutters, garage-door bracing).

The insurance-discount inspection (OIR-B1-1802 form) is the most important part of a hurricane retrofit because it's what unlocks the 5–15% annual insurance premium reduction — often $300–$1,200 per year. Many homeowners complete the structural retrofit but skip the insurance inspection because they think the building permit final inspection is enough. It is not. The building permit final inspection verifies that the work meets the Florida Building Code; the OIR-B1-1802 inspection verifies that the home now qualifies for the state's mandatory homeowners' insurance discount program, which is governed by Florida Insurance Commissioner rule. You must hire a separate licensed wind-mitigation inspector (distinct from the building inspector) to walk the home, photograph evidence of each retrofit component (roof-deck attachment, secondary water barrier, roof-to-wall straps, shutters, impact windows, garage-door bracing), and fill out the OIR-B1-1802 form. This costs $200–$400 and takes about 2 hours. Without this form signed and submitted to your insurer, your insurer will not apply the discount, even if you spent $10,000 on the retrofit. Many Casselberry homeowners are surprised to learn that the building permit and the insurance discount are separate processes with separate inspectors and separate fees — they are. Budget for both.

Three Casselberry wind / hurricane retrofit scenarios

Why Casselberry requires the OIR-B1-1802 insurance-discount inspection — and why your building permit isn't enough

Florida's homeowners' insurance market has been in crisis for the past five years, with insurers leaving the state, raising premiums, and tightening coverage. In response, the Florida Insurance Commissioner enacted mandatory homeowners' insurance discounts (up to 15%) for homes with documented wind-resistance retrofits. These discounts are governed by the OIR-B1-1802 Homeowners' Insurance Discount Inspection Form, which is the official state document that proves your home qualifies for the discount. A building permit final inspection from the City of Casselberry Building Department proves that your retrofit meets the Florida Building Code — but it does NOT prove to your insurance company that the retrofit qualifies for the state discount. Your insurer requires the OIR-B1-1802 form, which must be completed by a licensed wind-mitigation inspector (a separate credential from a general contractor or building inspector). Many Casselberry homeowners complete an expensive roof retrofit, get the building permit signed off, and then call their insurer expecting a discount — and the insurer says 'we need the OIR-B1-1802 form' and the homeowner realizes they need to hire another inspector and pay another $200–$400. This is frustrating but avoidable if you know upfront.

The OIR-B1-1802 form is a three-page document that the inspector fills out by hand or digitally, checking boxes for each retrofit component (roof covering, secondary water barrier, roof-to-wall connections, roof-to-gable-end walls, gable-end bracing, roof-deck attachment, openings protection, door/garage door bracing, masonry veneer reinforcement). The inspector must photograph each component, test fastener pullout samples (if applicable), and sign under oath that the work complies with the Florida Building Code. The insurer then reviews the form and applies the discount to the policy. Without this form, no discount. Casselberry Building Department does not sign the OIR-B1-1802 form — only a licensed wind-mitigation inspector can. This is a state-level requirement, not a Casselberry-specific rule, but Casselberry homeowners frequently get confused about it.

The insurance discount amounts vary by insurer and retrofit scope, but typical Casselberry homeowners see 5–15% reductions on their annual homeowners' insurance premium. For a home with an $1,200 annual premium, a 10% discount is $120 per year. A $300 retrofit cost plus $250 inspection fee is $550 total. Break-even is 4–5 years — well within the life of most roofs and shutters. Over 10 years, the savings are $1,200 minus the retrofit cost, which is substantial. This is why the OIR-B1-1802 form is not optional; it's the financial engine that makes most Casselberry hurricane retrofits cost-justified. Homeowners who skip it are leaving money on the table.

Casselberry's lack of online permitting and what that means for your retrofit timeline

Unlike nearby Orlando, Winter Park, or Altamonte Springs, which offer online permit portals with e-filing and real-time status tracking, Casselberry's Building Department still operates on a primarily in-person or phone-based permitting model as of 2024. This means you cannot submit your hurricane retrofit permit application online; you must either visit the City of Casselberry Building Department office in person (located at Casselberry City Hall) or call and request to submit by email or fax. The address and phone number are available on the city's website under 'Building Department' or 'Permits'. Operating hours are typically Monday–Friday, 8 AM–5 PM, but you should verify by phone because city hours vary seasonally and by staffing. This in-person requirement adds friction to the process: you cannot sit at home, fill out a form, and hit 'submit' and watch the status update in real-time. Instead, you submit in person or via email, get a confirmation by phone in 1–2 business days, answer any questions the plan reviewer may have over the phone or via follow-up email, and then come back in person (or have your contractor do so) to pick up the permit once it's approved.

For Casselberry homeowners working full-time jobs, this in-person requirement is inconvenient but not insurmountable. Most homeowners delegate the permit submission to their roofing contractor or shutter installer, who are accustomed to visiting the Casselberry Building Department in person and handling the paperwork. If you're doing a DIY retrofit or hiring a small local contractor unfamiliar with the Casselberry system, plan for 2–3 phone calls and 1–2 in-person visits before the permit is approved. Total time from first contact to permit issuance is typically 5–7 business days (compared to 1–2 days for cities with online portals). Once the permit is approved, you get a permit card (physical or printed) that you must post visibly on your property during construction. The building inspector will contact you by phone to schedule the in-progress inspection (usually 2–3 days after you call in) and the final inspection (usually 1–2 days after the work is complete).

The silver lining: Casselberry's in-person model means the plan reviewer is a real person who you can talk to on the phone or in person. If your permit application has an issue (e.g., missing HVHZ cert, incomplete strap specification), the reviewer will tell you directly and you can fix it same-day and resubmit, rather than waiting for an automated system to generate a rejection letter. Many Casselberry homeowners find this more efficient than fighting with an online portal. The key is to call ahead (don't just show up), confirm what documents and specifications you need to bring, and be prepared to have a quick technical conversation about your retrofit scope.
