Thinking about raising your Cape May cottage to stay ahead of coastal flooding and protect long-term value? You are not alone. Cape May’s low elevation and historic character make elevation projects both smart and nuanced. In this guide, you will learn how design choices, permits, and historic approvals work together in Cape May so you can plan with confidence. Let’s dive in.
Why raise a cottage in Cape May
Cape May sits in FEMA Special Flood Hazard Areas, so elevation is one of the most effective ways to reduce flood risk and improve resilience. The City’s Floodplain Management program offers resources, education, and Elevation Certificate guidance to help you plan wisely (City flood information).
New Jersey’s flood rules add protection beyond FEMA’s minimums. State regulations often require extra freeboard and define how elevation heights are set, which can influence costs and methods (NJDEP FHA rules).
Cape May is also a National Historic Landmark District. Any exterior change that affects your home’s appearance typically requires Historic Preservation Commission review to ensure work respects the city’s Victorian character (Cape May Historic District overview).
Know your required elevation
Your target height is based on the Local Design Flood Elevation, which reflects the most restrictive applicable standard for your lot. Start by confirming your flood zone, Base Flood Elevation, and LDFE with the City floodplain administrator (City floodplain office). NJ guidance explains how LDFE and freeboard apply to homes in coastal zones (NJDEP design bulletin).
In A or AE zones, the “lowest floor” is the regulated height. In coastal V or Coastal A zones, the “lowest horizontal structural member” is what must be elevated. This difference matters when you and your engineer choose a foundation.
Permits and approvals
Local permits in Cape May
You will apply through the City’s Construction & Zoning Office. They will confirm required “prior approvals” that must be in place before a building permit can be issued, such as HPC, Planning/Zoning, and any state permits (Construction & Zoning).
Historic Preservation Commission (HPC)
Raising a house changes exterior appearance, so you will likely need a Certificate of Appropriateness before the construction permit. Cape May’s updated Historic Design Standards include detailed guidance on flood mitigation and how to balance resilience with preservation (HPC design standards). Recent updates are summarized in a local announcement that highlights resiliency-friendly revisions (Design standards update overview).
State permits: NJDEP Flood Hazard and CAFRA
Depending on location and scope, New Jersey Flood Hazard permits and, in coastal areas, CAFRA approvals may apply. Some elevation projects qualify for permits-by-rule or general permits, while others require individual review. Your design team will align plans with N.J.A.C. 7:13 (NJDEP FHA rules and general permit guidance). Basements and habitable space below required elevations face strict limits (NJDEP basement guidance).
Federal guidance and insurance
FEMA offers technical publications on elevating homes and documentation you will need for insurance rating. After construction, an Elevation Certificate is used to confirm compliance and potentially support a map or rating change (FEMA elevation guidance).
Typical sequence and timelines
Confirm flood zone, BFE, and LDFE with the City floodplain office. Gather your flood data early so design targets are correct (City floodplain office).
Meet with Construction & Zoning to identify all prior approvals and application steps. Ask about HPC, Planning/Zoning, Water/Sewer, Soil Conservation, CAFRA, and local freeboard requirements (Construction & Zoning).
Hire a licensed architect and structural engineer experienced with coastal elevation, ASCE 24, and NJDEP rules. Plans must comply with the NJ Uniform Construction Code and applicable flood standards (NJ DCA code offices).
Submit complete applications. Under NJ DCA guidance, initial plan review for complete submittals is targeted within 20 business days, with resubmissions in 7 business days. Allow extra time for HPC hearing scheduling (NJ DCA review timelines).
If required, file NJDEP FHA or CAFRA applications in parallel. State reviews can add time and may require engineering documentation (NJDEP FHA general permit info).
During construction, schedule inspections at critical milestones. An Elevation Certificate is typically required after placing the lowest floor or structural member to document compliance (City flood ordinance reference).
Design and construction basics
Foundations that work here
- Piles or pilings elevate homes on open foundations suited to sandy coastal soils and are often preferred in coastal V zones (FEMA elevation guidance).
- Pier and beam systems use columns or piers to create required open flow beneath the house (FEMA elevation guidance).
- Raising the structure and building a new foundation can be feasible, but it is more invasive. New basements are generally not permitted in flood hazard areas (NJDEP basement guidance).
Utilities and enclosures
Locate HVAC, water heaters, and electrical panels above the LDFE or protect them per ASCE 24. If you enclose space below the elevated floor, it is typically limited to parking, access, or storage and must include compliant flood openings (NJDEP design bulletin and City flood ordinance reference).
Preserving historic character
Plan to retain or reconstruct visible features like porches, railings, and trim to maintain streetscape harmony. Place new stairs or ramps in less prominent locations and use in-kind materials where feasible. The HPC’s updated standards provide examples tailored to resiliency projects (HPC design standards and standards update overview).
Budget, contractors, and insurance
Costs vary widely based on soil, access, structure type, and foundation work. Get detailed, itemized bids from contractors with coastal elevation experience and confirm local licensing. The City enforces UCC requirements and can outline permitting expectations (Construction & Zoning). For planning tradeoffs and options, FEMA publications are a helpful reference (FEMA elevation guidance).
After you elevate, obtain a surveyed Elevation Certificate for insurance rating. This document is key for potential NFIP premium changes or map actions like LOMA/LOMR. The City’s flood page explains local resources and insurance outreach (City flood information).
Quick homeowner checklist
- Verify your flood zone, BFE, and LDFE with the City floodplain office and FEMA maps (City flood information).
- Call Construction & Zoning for a pre-application checklist and required prior approvals, including HPC, Planning/Zoning, and any state permits (Construction & Zoning).
- Contact the HPC early and review the Historic Design Standards to set expectations for visible changes (HPC design standards).
- Hire a licensed architect/engineer with ASCE 24 and NJDEP experience to design foundations, utility elevations, and flood openings (NJDEP design bulletin).
- Submit complete plans to the City and, if required, to NJDEP. Budget time for DCA review timelines and HPC scheduling (NJ DCA review timelines).
- During construction, schedule inspections and secure the Elevation Certificate, then obtain your Certificate of Occupancy (City flood ordinance reference).

FAQs
Will raising my Cape May cottage reduce flood insurance costs?
- Often yes, but NFIP rating depends on your final surveyed Elevation Certificate and any map changes; confirm details with your insurer and review City resources on flood insurance (City flood information).
How high do I need to elevate in Cape May?
- Your target is the Local Design Flood Elevation, which includes required freeboard; verify the value for your lot with the City floodplain administrator and reference NJDEP guidance on LDFE (City floodplain office and NJDEP design bulletin).
Do I need Historic Preservation Commission approval to raise my home?
- Yes in most cases, because raising changes exterior appearance; a Certificate of Appropriateness is typically required before a building permit (HPC design standards).
How long does permitting take for an elevation project?
- NJ DCA targets first plan review in 20 business days for a complete submission, with added time for HPC hearings and any NJDEP reviews; many projects take several months to a year depending on complexity (NJ DCA review timelines).
