Biscayne Park Housing Guide: Homes, Lots, Age, Ownership
Biscayne Park is a village of older, low houses on large lots, with more two-unit buildings than its single-family reputation suggests. This guide shows what is built here, how big and how old it is, who owns it and for how long, and what the county's assessed values can and cannot say about the cost of holding a home.
💡 Key Insights & Takeaways
- The village has 1,064 residential parcels as of 15 October 2026, and 189 of them are duplexes, so Biscayne Park is not a single-family-only place.
- The median house has 1,703 square feet of living area on a lot of 10,850 square feet, and 92.8% of houses are one story.
- The median house or duplex was built in 1949, and 56.7% were built before 1950. Only 5.8% of houses carry an update date of 2010 or later.
- The median house or duplex is 8.1 years past its last recorded transfer, and that figure is understated by about 8.5 months because the ownership data ends on 30 January 2026.
- Land makes up a median 78.8% of the county's total valuation, which is not market value, and the data holds no tax bills, so this page cannot say what you would pay in tax.
If you are weighing a Biscayne Park house, one figure matters: a homesteaded house is assessed at a median of 36.3% of its just value, the county's pre-cap valuation, against 96.6% without the exemption, as of 15 October 2026. The gap comes from the Save Our Homes cap, not the house, and neither value is market value.

What kinds of homes are in Biscayne Park?
Biscayne Park is mostly houses with a large block of duplexes, and it is not a single-family-only village. As of 15 October 2026 it has 1,064 residential parcels: 845 houses, 189 duplexes, 8 buildings of three or more units and 22 vacant lots. The county lists no condominiums here. The count leaves out 16 parcels that are public, religious or similar.
Residential parcels in Biscayne Park by type, as of 15 October 2026 (n = 1,064).
| Parcel type | Parcels | Share of residential parcels |
|---|---|---|
| Houses | 845 | 79.4% |
| Duplexes | 189 | 17.8% |
| Buildings of three or more units | 8 | 0.8% |
| Vacant lots | 22 | 2.1% |
The county's zoning codes tell a different story from the buildings. Of the 1,064 residential parcels, 40.9% carry the duplex zoning class and 59.1% carry the general single-family class. Only 189 parcels are built as duplexes. A duplex zoning class does not prove that you may build a second unit, so confirm the parcel's zoning, lot and flood requirements with the Village before you assume one.
Inside the houses, 92.8% are one story and 7.2% have two or more stories. The median house has 3.0 bedrooms and 2.0 bathrooms. A single bathroom serves 30.8% of houses, and 17.9% have three or more (n = 845). Duplex records hold totals for the whole building, so this page reads bedroom and bathroom counts for houses only.
How big are Biscayne Park houses and lots?
The median house has 1,703 square feet of living area on a lot of 10,850 square feet, across 845 houses as of 15 October 2026. The lots are big next to the buildings on them. The floor area ratio, which is living area divided by lot area, has a median of 0.153.
A duplex building has a median of 1,865 square feet of living area across both units (n = 189). These are the county's living areas, which often differ from the sizes in a listing, so a listing's square footage will not match them.
How old are Biscayne Park homes, and how many have been updated?
The median house or duplex was built in 1949, across 1,034 parcels as of 15 October 2026. Of those, 56.7% were built before 1950 and 1.8% were built after 2000. Most of what you tour here is a mid-century building.
The county also records an effective year. That is an adjusted age date that moves later than the year built when the county judges a house to have been updated, and it is a valuation convention, not a permit record. By that measure 55.3% of houses (n = 845) carry an effective year later than their year built. The median effective year is 1961, though, and only 5.8% of houses carry an effective year of 2010 or later. So the updates that exist are mostly decades old, and if you plan to renovate you should expect real work.
Who owns Biscayne Park homes, and for how long?
Most houses here carry the homestead exemption, which points to owner-occupancy. The homestead exemption is a Florida property tax break on an owner's main home, and it is the closest thing this data has to an owner-occupancy count. It appears on 71.4% of houses and duplexes (n = 1,034) and on 78.2% of houses (n = 845), as of 15 October 2026.
The median house or duplex has gone 8.1 years since its last recorded transfer (n = 1,030). Of these parcels, 41.3% have gone more than 10 years, 21.1% more than 20 years and 8.3% more than 30 years. Parcels with the exemption hold longest. Hold years run from the last recorded transfer of any kind, so a family or trust transfer resets the clock even when the household did not change. The ownership data also ends on 30 January 2026, which is 8.5 months before the as-of date, so every hold length here is understated by about that much.
Years since the last recorded transfer, houses and duplexes, data to 30 January 2026 (each figure understated by about 8.5 months).
| Group | Median years since last transfer | Parcels (n) |
|---|---|---|
| All houses and duplexes | 8.1 years | 1,030 |
| With the homestead exemption | 9.7 years | 736 |
| Without the homestead exemption | 5.0 years | 294 |
Within that same data window, 10.0% of the 1,030 parcels were acquired on or after 30 September 2024. No transfer after 30 January 2026 can show, so that share is a floor.
Entities own 19.4% of houses and duplexes (n = 1,034). Trusts hold 7.2%, corporate or LLC owners 12.6% and institutions 0.1%. Most trusts are an estate-planning choice and are not read as an investor buying in, so the corporate or LLC share is the closest figure to investor ownership. Mailing addresses are in another state for 2.6% of parcels. That is a minimum, because an owner can hold a home here and mail to a Florida address.
What do assessed values say about the cost of holding a Biscayne Park home?
This page cannot tell you what a Biscayne Park tax bill is, because the data holds no tax bills. What it does hold is the county's assessed value. Assessed value is the county's estimate under the Save Our Homes cap, a Florida limit on how fast the assessed value of a homesteaded home can rise. It is not market value, worth or what a home would sell for. Just value is the county's valuation before the cap.
The median assessed value of a house or duplex is $403,853 (n = 1,034, as of 15 October 2026). Land makes up a median 78.8% of the county's total value, and land is more than half of that total on 98.2% of houses and duplexes. For houses, the median assessed value is $216 per square foot of the county's living area, which often differs from a listing's size (n = 845). That figure measures the assessment, never a market price per square foot.
Houses in Biscayne Park by homestead status, as of 15 October 2026. Assessed values are county estimates under the cap, not market value.
| Measure | With the homestead exemption | Without it |
|---|---|---|
| Houses (n) | 661 | 184 |
| Median assessed value | $295,688 | $685,883 |
| Median just value | $776,572 | $768,994 |
| Median assessed value as a share of just value | 36.3% | 96.6% |
The two groups have almost the same median just value, so the gap is the cap and not the property. The median capped benefit on a homesteaded house is $474,831, which is the difference between its just value and its assessed value. The data cannot show whether the assessed values already take off the homestead exemption itself. The cap resets on a qualifying sale, so a seller's assessment is not the one a buyer inherits. Comparing assessed values across homes bought in different years reflects the year of purchase more than today's relative market value.
The same pattern shows against the last qualified recorded sale price. Across 623 parcels, assessed value sits at a median of 0.98 times that price. For parcels last sold before 2000 (n = 91) it is 1.82 times, because the cap has had longest to build, and for 2000 and later (n = 532) it is 0.93 times. In all, 10.6% of the 623 sit at 2 times or more, and 37.7% sit below 0.90 times. These ratios use sales recorded only to 30 January 2026, so they miss every later sale.
How much redevelopment pressure is there in Biscayne Park?
The data points to a pool worth a site check, not a forecast of rebuilds. A five-test score on the county's land and building values flags 21.5% of houses as strong rebuild candidates and another 12.1% as moderate (n = 845, as of 15 October 2026). Treat 21.5% as a ceiling. Three of the five tests are quartile cuts, and two read the same land and building values, so the score runs high by design and not because of missing data. It does not say that any house will be torn down.
The 22 vacant lots are the clearer pool, with a median lot of 10,650 square feet. Entities hold 72.7% of them, against 19.4% of houses and duplexes. The median hold on a vacant lot is 4.5 years, understated by about 8.5 months because the ownership data ends on 30 January 2026. A hold that short fits recent buying more than land held for generations.
