Casselberry is a 29,500-resident city in south-central Seminole County, Florida, immediately east of Altamonte Springs and immediately north of Winter Park. ZIP 32707 covers the central core around Lake Concord Park and the Triplet Lakes chain. ZIP 32708 covers the eastern Deer Run pocket and the Lake Howell shoreline. ZIP 32730 covers the southwestern Fern Park district. The city's median household income is $57,816, and the assigned high school for most addresses is Lake Howell High School on Dike Road.
Where it actually is
Casselberry is a separate municipality in Seminole County. The city sits east of Altamonte Springs and north of Winter Park, roughly 10 miles north of downtown Orlando, with no I-4 frontage. The city is shaped by State Road 436 (Semoran Boulevard) running east to west across the southern half, US Highway 17/92 running north to south on the west edge, and Tuskawilla Road defining the east edge into Oviedo.
Three ZIPs map to the city. ZIP 32707 covers the central residential core, including Casselberry City Hall, Lake Concord, and the Triplet Lakes (Lake Triplet, Mirror Lake, and Lake Florence). ZIP 32708 covers the eastern lobe around Red Bug Lake Road, including the 1980s Deer Run subdivision and the Lake Howell shoreline. ZIP 32730 covers the southwestern Fern Park district on the west side of US 17/92.
The borders, in driving terms: Altamonte Springs is west, Winter Springs and Oviedo are east, Winter Park is south (the Howell Branch Road and Aloma Avenue boundary), and Longwood is north. The city covers roughly seven square miles, with more than 30 lakes and ponds inside its limits per the city parks directory.
The 2023 estimated population is 29,500 and the U.S. Census Bureau QuickFacts profile tracks the same municipal boundary, making Casselberry the 137th most populated city in Florida. It is meaningfully smaller than Altamonte Springs to the west and meaningfully quieter, with no enclosed mall, no I-4 interchange, and no medical campus the scale of AdventHealth. The city's character is set by the lakes, the older residential subdivisions, and the slow east-west traffic along SR 436 and Red Bug Lake Road.
What it feels like to drive in
You enter Casselberry from Altamonte Springs heading east on SR 436, and the first thing the road does is widen. The mall corridor gives way to a quieter commercial strip of older retail buildings, mid-century banks converted to dental offices, and a few legacy plazas built around the 1970s expansion of the city.
A few blocks north of SR 436, the residential grid takes over. Triplet Lake Drive curves around the central chain of lakes through one of the city's oldest 1950s and 1960s subdivisions. Casselberry City Hall sits on the shoreline of Lake Concord, surrounded by nine acres of Lake Concord Park. The oak canopy here is heavy. The city notes that some of the oaks in the park are 150 years old, which puts them on site before the city's 1940 incorporation.
Drive east along Howell Branch Road and the city changes character. The road threads the southern boundary against Winter Park and Goldenrod. Past Lake Howell Road, the 32708 ZIP opens into the Deer Run subdivision, the 1980s master-planned community that anchors the eastern Casselberry single-family inventory. Deer Run's grid follows a golf-course centerline, with the residential streets fanning out from Howell Creek toward Tuskawilla Road.
Drive west on SR 436 and you exit the city quickly into Fern Park (ZIP 32730), which is technically inside Casselberry's municipal limits but feels like its own commercial district. The southwest district holds an older mix of small retail and the English Estates Elementary School attendance zone.
The lakes are the consistent feature. The Triplet Lakes through the center, Secret Lake and Lake Kathryn on the north, Lake Howell on the east, and the unnamed retention ponds threaded through every subdivision. Most residential blocks in 32707 have water within two blocks of any front door.
Who lives here
Casselberry's 2023 population is 29,500, per the most recent ACS-derived city profile. The median household income is $57,816 and the per capita income is $32,641 per the same Data USA compilation. ZIP 32707 reports a higher zip-level median of $66,780, which is the inland-residential-only slice of the city without the Fern Park commercial drag on the average.
The median age is 37.6 years per Data USA. That is younger than the Seminole County overall median but older than Altamonte Springs to the west. The age curve reads as a long-tenured homeowner population in the older 1960s and 1970s subdivisions around the Triplet Lakes, plus a younger family slice in the 1980s and 1990s Deer Run product on the east side.
The largest racial and ethnic groups, per Data USA, are White (53.1 percent), Hispanic of any race (27.4 percent), and Black or African American (9.6 percent). The poverty rate stands at 13.7 percent. The owner-occupancy share is higher than Altamonte Springs (where the mall-corridor rental stock pulls the citywide rate down) and lower than Lake Mary to the north.
Owner-occupancy and inventory pattern matter to anyone underwriting here. Casselberry's resale market is built around long-tenured owners trading out of homes they bought in the 1980s and 1990s. The Triplet Lakes single-family inventory turns over slowly, with average days on market in the 30-to-45 day range for renovated stock under $400,000. Lake-adjacent listings on Lake Howell carry a 15-to-25 percent premium per square foot above comparable inland inventory in the same zone.
Schools
Public schools in Casselberry are zoned by Seminole County Public Schools, the same district that covers Altamonte Springs, Lake Mary, Oviedo, and Sanford. School zoning splits north-south down the middle of the city, with most central addresses zoned to Casselberry Elementary, South Seminole Middle, and Lake Howell High.
Casselberry Elementary School is the central-core K-5, serving the residential pockets around Lake Concord and the Triplet Lakes, per Seminole County Public Schools school information. The school is inside the city limits, walking distance from Lake Concord Park.
English Estates Elementary School at 299 Oxford Road in Fern Park serves the western and southwestern portions of the city, including most of ZIP 32730 and parts of southern 32707. The school's attendance boundary catches a significant share of the Fern Park residential inventory.
South Seminole Middle School at 101 South Winter Park Drive is the assigned middle school for most Casselberry addresses. GreatSchools rates it 5 out of 10. Enrollment is 1,084 in grades 6 through 8 with a 19-to-1 student-teacher ratio. The school runs a Gifted and Talented program and 14 sports.
Lake Howell High School at 4200 Dike Road is the assigned high school for nearly all Casselberry addresses. The school's official address sits in Winter Park ZIP 32792, but the attendance zone catches most of Casselberry. GreatSchools rates it 6 out of 10. Enrollment is 2,244 in grades 9 through 12 with a 22-to-1 student-teacher ratio. The graduation rate is 96 percent and the average GPA is 3.41 per U.S. News. U.S. News ranks the school 165th in Florida. The school runs AP coursework, 27 sports programs, and a Gifted and Talented track.
The eastern slice of the city near Tuskawilla Road may feed into the Oviedo and Hagerty feeder pattern depending on the specific address. Some Casselberry addresses on the Longwood-side north edge zone to Lyman High School at 865 South Ronald Reagan Boulevard.
A practical note for parents: the Seminole County Public Schools attendance boundary is the controlling document, not the city limit or the ZIP. Confirm any school-zone claim with the official SCPS school zone search before relying on listing copy. The Casselberry-to-Oviedo and Casselberry-to-Lyman boundary lines have shifted in recent rezones and listing sheets sometimes lag the most recent update.
Housing stock
Single-family housing in Casselberry runs primarily 1960s through 1990s product, with limited 2010s and 2020s infill. The architectural mix on a residential block walk: 1960s and 1970s concrete-block ranch (the dominant style across 32707), 1980s and 1990s split-level (concentrated in Deer Run on the east side), and a thin layer of mid-century stock around the Triplet Lakes that predates the city's 1970s growth.
The 32707 ZIP median home value is $305,000 per the most recent ACS-derived ZIP profile, with a current median list price of $353,420 per Zillow's 32707 market snapshot. The 32708 ZIP carries a higher median list price of $428,084 citywide per Zillow's Casselberry single-family inventory, reflecting the newer Deer Run product and the Lake Howell lakefront premium.
Lot sizes split by sub-area. The Triplet Lakes pocket inside 32707 holds quarter-acre to third-acre lots on curved streets with mature canopy. The Deer Run subdivision on the east side runs slightly smaller lots, typically 7,000 to 9,000 square feet, on the planned-community grid. Lake Howell shoreline lots can run to half-acre and above. The Fern Park district in 32730 carries the smallest typical lot sizes in the city.
Inventory on Zillow as of the research date shows 31 active single-family listings in 32707 and 86 citywide. Townhome inventory in 32707 runs at seven active listings, a meaningful slice of the local attached product.
Tear-down and new-construction activity is limited compared to neighboring Winter Park to the south or Lake Mary to the north. Most updates in Casselberry are renovation-flip plays inside the 1970s and 1980s envelopes, with the typical investment going into kitchen, bath, flooring, and exterior paint rather than full additions or rebuilds.
What's selling now
Three snapshot views of active Casselberry inventory, sampled on the research date. The market here splits by ZIP, so the snapshot table tracks the inventory at the ZIP level rather than pulling three individual addresses.
The 32707 single-family snapshot at 31 active listings with a $353,420 median is the inland-residential core. The typical 32707 listing is a 1970s or 1980s three-bedroom or four-bedroom concrete-block ranch on a quarter-acre lot, between 1,400 and 2,200 square feet, between $325,000 and $475,000.
The citywide snapshot at 86 active listings with a $428,084 median pulls in the 32708 Deer Run product and the Lake Howell shoreline inventory, which carry the higher end of the typical four-bedroom range up to $600,000 for renovated stock and above $700,000 for usable-shoreline lake lots.
The 32707 townhome inventory at seven active listings is the attached product slice. Casselberry's 1980s buildout produced a meaningful townhome share along the SR 436 corridor and around Lake Triplet, which keeps the entry-level attached price below the single-family floor.
The pattern across the inventory: Casselberry single-family buyers under $400,000 are mostly first-time buyers and Seminole County move-up families trading out of older Altamonte Springs condo stock. The $400,000-to-$600,000 band is the family-relocator slice locked onto the Lake Howell High zone. Above $600,000 the buyer pool gets specifically lake-driven and the inventory thins to a handful of shoreline listings per quarter.
Days on market is the second variable. Renovated 32707 single-family stock between $325,000 and $475,000 typically transacts inside the first 30 days when the school zone is clearly Lake Howell High and the renovation depth is visible from the listing photos. Above $500,000 the typical days-on-market stretches to 45 or 60. Lakefront on Lake Howell or any of the Triplet Lakes carries a measurable premium when the dock and shoreline are usable and a sharp discount when they are not. The shoreline-condition question is the first one an agent should answer before scoping the listing photo package.
Renovation depth matters more than envelope size in this market. A 1,500-square-foot fully renovated ranch with a new roof, new HVAC, and a clean kitchen will outprice a 2,200-square-foot half-renovated home on the same block. Casselberry buyers underwriting in the $300,000-to-$500,000 range have priced in the cost of finishing the work themselves, and they price-down accordingly.
Where locals actually go
The center of gravity is Lake Concord Park. The nine acres surrounding Casselberry City Hall, with the 150-year-old oak canopy, the interactive water play area, the amphitheater, the sculpture garden, and the boardwalk along the lake, are the city's central public space. The park hosts the Casselberry Jazz concert series and the rotating programming at the Casselberry Art House.
The history runs deeper than the park structure. The northeast shore of Lake Concord was the site of the 1849 Fort Concord blockhouse, a Seminole Wars fortification per the Casselberry timeline. The fort is gone but the lake name is the direct lineage.
The Triplet Chain of Lakes is the working spine of central 32707. Lake Triplet, Mirror Lake, and Lake Florence connect through canals and shoreline parks. Most residential blocks in the central core sit within two streets of one of the three.
The Lake Howell shoreline on the east edge of the city is the largest lake inside Casselberry's limits. It anchors the Lake Howell High School zone, which is the school district line that drives most family-buyer demand in 32708.
Secret Lake Park and Wirz Park are the residential-scale parks that round out the central park network. Both sit inside the Triplet Lakes residential pocket and serve as the working neighborhood spaces for the surrounding 1970s subdivisions.
The Howell Branch Road corridor on the south boundary is where Casselberry buyers and Winter Park buyers overlap on the dining side. The corridor's restaurant and retail mix sits in Winter Park ZIP 32792 technically, but functions as a shared south-side strip for both cities.
The Casselberry Jazz series at Lake Concord Park runs through the spring and fall seasons, with rotating local programming on the lakefront amphitheater stage. The series is the city's most consistent draw outside the residential pockets and is the recurring weekend anchor for the 32707 core. Most attendees walk from the surrounding residential streets, which keeps the parking pressure on the city hall lot rather than the surrounding subdivisions.
The photographer's read
A working note from Aerial Shots Media on shooting in Casselberry. The lakes are the central frame here, and most listings inside 32707 sit within two blocks of one of the four named lake systems. That makes drone aerials a higher-value component of the typical package than in a non-lake Seminole ZIP.
The Triplet Lakes residential streets carry heavy oak canopy on most blocks. Front elevations between 11 a.m. and 2 p.m. sit in dappled shadow that reads patchy. Schedule front-elevation stills pre-10 a.m. or post-4:30 p.m. The Lake Howell shoreline on the 32708 east side has a cleaner sun line because the lake itself opens the canopy.
Sunrise drone passes on Lake Howell read cleanly when the lake is glass, which is most weekday mornings before the Sunday boat traffic kicks in. Sunset twilight from the Lake Concord boardwalk gives a strong west-facing frame with the City Hall and oak canopy as foreground. Sunset behind Lake Howell hits roughly 6:35 p.m. in October.
Orlando Class C airspace covers the southern half of the city. The Orlando Executive Airport Class D shelf approaches from the east. Both require LAANC for any altitude. Under-100-foot residential work is straightforward. We avoid SR 436 low passes during commute windows and the Howell Branch Road corridor on the south boundary, which is dense with overhead utility lines.
The best months for an exterior package here, in order: March, April, October, November, February. Summer afternoon thunderstorms compress the usable window and stack same-day reschedule risk, particularly for twilight passes that depend on a clean western horizon.

If you are working a listing here and the address is inside Casselberry, the package we default to is a stills plus drone exterior package with optional twilight and 3D tour. We are FAA Part 107 certified for the drone work and Zillow Showcase certified for the Showcase listing tier. Coverage runs across Orange, Seminole, Lake, Osceola, Polk, Hillsborough, Brevard, and Volusia counties.
For a 32707 or 32708 single-family scope, the most common add-on agents request is a Lake Howell or Triplet Lakes drone reveal for lakefront listings. The second is a twilight pass on the front elevation. The third is a Lake Concord Park lifestyle b-roll segment for listing videos targeting buyers relocating from out of state who want a sense of the public-space inventory before the showing.
