Trying to choose between Avalon and Stone Harbor as a buyer? That comparison can feel harder than it looks, especially when both towns share the same barrier-island setting and attract many second-home buyers. If you want a clearer way to think about inventory, home styles, and rental-use differences, this overview will help you compare the two markets in practical terms. Let’s dive in.
Avalon and Stone Harbor share a resort market
Avalon and Stone Harbor are the two boroughs associated with Seven Mile Island in Cape May County. That shared setting matters because buyers are often comparing two nearby shore markets with a lot of the same broad appeal.
At the same time, both towns are highly seasonal. Avalon’s 2022 master plan reported 5,434 housing units, with only 692 occupied units year-round and 4,742 listed as vacant, including 4,562 seasonal, recreational, or occasional-use units. Stone Harbor’s 2025 Housing Element and Fair Share Plan reported 3,207 housing units in 2020, with 402 occupied units and 2,805 vacant units, including 2,568 seasonal or recreational-use units.
That seasonal pattern is not a side note for buyers. It shapes how neighborhoods feel in the summer, how homes are used, and how ownership decisions often center on second-home living, seasonal stays, and rental planning.
Avalon offers a larger housing base
If you want more overall inventory to choose from, Avalon starts with a larger housing base. The borough’s reported 5,434 housing units are meaningfully higher than Stone Harbor’s 3,207 units.
That does not automatically mean shopping is easy. Both markets are limited coastal markets, but Avalon’s larger unit count can give you more opportunities to compare property types, locations, and price points within the island setting.
For buyers coming from off-island, that broader supply can be helpful. You may be able to look at more block-by-block options before deciding what matters most, whether that is beach access, bay proximity, a certain home style, or rental flexibility.
Property types differ between the towns
One of the biggest practical differences is the type of housing stock you are likely to see. Avalon’s 2022 master plan describes development as overwhelmingly residential, with much of the borough in single-family zoning districts and smaller portions in two-family districts, along with limited hotel, business, and marine-business land.
Specifically, Avalon reports 42.12% of borough land in the R-1C single-family district and 39.34% in the R-1B single-family district. It also reports 6.03% in R-2A and 5.86% in R-2B two-family districts. That mix suggests a market with strong single-family character but some added variety in housing form.
Stone Harbor’s housing data shows a more concentrated unit mix. Its 2023 ACS-based inventory reports 70.6% detached single-family homes, 17.2% attached single-family homes, 6.5% two-unit buildings, and relatively small shares in larger multifamily categories.
For you as a buyer, that can shape the search experience. Avalon may present a broader mix of single-family homes, two-family opportunities, and some higher-density pockets, while Stone Harbor leans more heavily toward detached and attached homes.
Stone Harbor skews more detached-home heavy
Stone Harbor’s numbers point to a market centered on detached housing. With more than 70% of units classified as detached single-family and another 17.2% as attached single-family, the borough has a housing profile that many buyers will experience as more uniform.
That can appeal to buyers who want a market that feels more consistently residential in its housing form. It may also simplify your search if your main goal is a traditional shore home rather than a broader mix of property configurations.
Stone Harbor also reports that 47.9% of its housing stock was built before 1980, with 6.9% built before 1940. For buyers, that can mean more variation in age, updates, and renovation needs from one listing to the next.
Rental rules can affect your buying strategy
If rental use matters to your plan, local rules deserve close attention before you buy. In these towns, rental definitions and licensing requirements are not identical, and those differences can shape how you evaluate a property.
Avalon defines a short-term rental as any lease or tenancy for less than 175 consecutive days. The borough also defines a seasonal rental as any rental between May 1 and September 30.
Stone Harbor uses a different seasonal framework. Its rental code defines a seasonal tenant as someone entering into a lease with a term of 125 days or more per year.
These are not just technical details. They can influence how you think about personal use, seasonal occupancy, and whether a home fits your goals as a second home, an occasional rental property, or a more structured seasonal asset.
Avalon may suit flexible rental planning
Avalon’s code is easier to read as a market with explicit short-term rental language. For buyers who are considering some level of rental activity along with personal use, that can make the town especially relevant during your comparison stage.
Avalon also requires all rental properties to be registered, inspected, and licensed each year. Owners whose record address is outside Cape May County must designate a Cape May County resident, business, or realtor as the local agent for notices and service of process.
The borough also requires proof of at least $500,000 in liability coverage. If you live out of the area, these requirements are a reminder that owning a shore property with rental use can involve local coordination, annual compliance, and practical on-the-ground support.
Stone Harbor leans toward longer seasonal use
Stone Harbor also requires rental properties to be registered, inspected, and licensed annually. Borough materials say the registration system supports fire safety, construction, zoning, and public-safety response.
Its liability insurance requirements vary by property type. Certain small multifamily rental properties with one owner-occupied unit require at least $300,000 in coverage, while other rental units require at least $500,000.
For many buyers, Stone Harbor reads as a market more closely tied to longer seasonal occupancy and traditional shore-house use. If your plan centers on extended personal stays or a more classic seasonal pattern, that framework may fit what you want.
Lifestyle fit is often block by block
A smart comparison is not really about asking which town is better. It is about understanding how each market lines up with the way you want to use the property.
Avalon’s larger housing stock and more varied zoning can create more choice from one part of town to another. Its master plan also notes summer congestion and parking pressure in denser areas, especially in the R-2A area.
Stone Harbor’s smaller housing base and heavier concentration of detached homes can come across as more uniform and more residential in feel. For some buyers, that is a plus, especially if they want a quieter resort setting within the same island environment.
This is where local guidance matters. Two homes that look similar on paper can offer very different ownership experiences depending on location, surrounding density, access patterns, and likely seasonal activity nearby.
Household data adds another clue
Household-size data offers one more way to understand the two markets. Avalon’s master plan reports an average household size of 1.93.
Stone Harbor’s 2025 Housing Element and Fair Share Plan reports an average household size of 1.77 and states that non-family households make up 44.1% of households. That points to a somewhat smaller-household profile in Stone Harbor.
You should not treat that as a rule for every buyer or every block. Still, it is useful market context when you are trying to picture how each town functions outside the summer rush.
How to compare Avalon and Stone Harbor
When you narrow your search, focus on how you plan to own the property, not just how the listing looks online. A good comparison usually starts with a few practical questions.
Ask yourself:
- Do you want the broadest possible mix of property types?
- Are you mainly looking for a detached single-family shore home?
- Will you use the property mostly for personal stays, seasonal occupancy, or some rental activity?
- How important is short-term rental language in the local code?
- Are you comfortable managing annual rental registration, inspection, and insurance requirements?
- Do you prefer a setting with more housing variety or one that feels more uniform?
For many buyers, the answer becomes clear once those questions are on the table. Avalon often makes sense for buyers who want broader property-type choice and more explicit short-term rental language, while Stone Harbor often appeals to buyers looking for a smaller, more detached-home-focused market with longer seasonal occupancy patterns.
A local view helps you buy smarter
On Seven Mile Island, market differences are rarely abstract. They show up in zoning, housing mix, rental rules, and the way a property actually works for your family or investment goals.
That is why many out-of-area buyers benefit from a year-round local perspective. When you are comparing Avalon and Stone Harbor, it helps to have someone who can explain not only the listing, but also the block, the town rules, and the ownership tradeoffs that are easy to miss from a distance.
