Barndominium Builders in Palm Bay, FL

Southwest Palm Bay holds nearly five thousand vacant quarter-acre lots, platted in the 1960s by a developer that went bankrupt in 1991 and never came back. There is no water, sewer or power out there and the whole area sits in a flood zone, which is exactly why the land is cheap. What the city asks in return is a minimum house size and a 25 foot height limit that catch a lot of barndominium plans out.

Building conditions in Palm Bay

What actually changes from one Florida city to the next: who issues the permit, what wind speed the structure has to be engineered to, and what the ground is like. These are the numbers your drawings have to satisfy.

Build conditions for Palm Bay, drawn from the sourced facts on this page. Every figure above is cited in the quick-facts panel below, with its source and vintage.
Minimum house size, by district
Between 800 and 1,800 sq ft of living area depending on zoning. SRE wants 1,800, RE 1,600, RS-1 1,400, and GU, RR and RS-2 all want 1,200. Only RS-3 at 800 sq ft accommodates a genuinely compact build.

Palm Bay Land Development Code Table 173-4. A 900 to 1,100 sq ft living core fails in every single-family district except RS-3.

Height limit is 25 feet in most of the city
Only the GU and RR districts allow 35 feet. Everywhere else the cap is 25, which a tall shop bay with a 14 foot door will not clear. Accessory buildings are capped at 25 feet or the height of the house, whichever is lower.

Palm Bay LDC Table 173-4 and section 174.002(B). GU needs a 5 acre lot, RR a 1 acre lot.

The Compound
4,978 vacant platted parcels across three subdivisions in southwest Palm Bay, held by 2,755 owners worldwide, served by 200 miles of ageing roads and no water, sewer or electricity at all. The entire area is in a flood zone.

City of Palm Bay. Platted by General Development Corporation, which went bankrupt in 1991. Named a priority site in a $1.5M EPA Brownfields assessment grant in 2024.

Impact glazing is required citywide
Every parcel in Palm Bay is in the wind-borne debris region, including the far western edge miles from any water. The design wind speed clears 140 mph across the whole city, which triggers the requirement on its own.

FBC 1609.2 second criterion. The 140 mph contour sits 28 km beyond the western city limit, so the one-mile coastal test never has to be applied.

Design wind speed
Essentially 150 mph. The 150 mph contour runs roughly north to south through the middle of the city, giving about 147 mph at the western limit rising to 153 at the eastern.

Measured against the adopted FBC 2023 contour dataset. Brevard accepted the state map as drawn with no local adjustments.

You cannot build the shop first
No accessory building may be erected without a principal building already present, and it cannot be used until the house is complete and has a certificate of occupancy. The barn-first, live-in-it-while-you-build plan does not work here.

Palm Bay LDC section 174.002(C). Alachua County has the same rule; most rural Florida counties do not.

Also worth knowing before you build in Palm Bay

Bare metal is restricted on outbuildings
A metal accessory structure over 300 sq ft or over 12 feet tall must be designed to look like non-metal construction, textured-coated on all four sides, or painted to match the house. Fail that and it is capped at 12 feet.

Palm Bay LDC section 174.002(G). This governs accessory structures only; we found no equivalent restriction on a principal dwelling, though confirm with Growth Management.

The shop cannot outsize the house
Unless you are on RR-zoned land of two acres or more, accessory structures may not exceed the size of the principal building. RR at two acres is the one route to a shop larger than the house.

Palm Bay LDC section 174.002(D). Unincorporated Brevard caps accessory buildings far lower still.

Impact fees rise on 1 October 2026
The city is phasing fees in over four years. A single-family home is $8,024.12 today and $8,645.60 from 1 October, a $621 increase. Transportation is the same whether the house is 1,400 sq ft or 3,000.

Palm Bay Resolution 2025-33. Brevard County levies its own fees on top under an interlocal agreement, so do not treat the city figure as the total.

The canal district permits before the city does
If your lot touches a Melbourne-Tillman canal, the city will not issue a permit involving access along it until the water control district has issued one. That district runs 163 miles of canals across southwest Palm Bay.

City of Palm Bay Building Department; Melbourne-Tillman Water Control District, established 1922, 321-723-7233. A real scheduling trap on Compound lots.

Floodplain permit comes before the building permit
Any lot with a flood zone designation other than X or X500 needs a floodplain permit from Land Development before a building permit will issue. In the Compound that is every lot.

City of Palm Bay Land Development, 321-733-3042.

Ground conditions, the toughest on our list
88.5% of rated county acreage rates Very Limited for dwellings, the highest figure of any market we build in. The cause is a water table sitting 18 to 30 inches down, plus ponding and flooding.

USDA NRCS survey FL009. Every dominant mineral soil in Brevard is poorly or very poorly drained. It is a drainage and elevation problem, not a bearing one.

Almost no sinkhole risk
Brevard has 4 reported subsidence incidents out of 4,443 statewide, none verified as an actual sinkhole, ranking it 46th of the 60 counties reporting anything. None of the four is inside Palm Bay.

Florida Geological Survey subsidence reports. For scale, Hillsborough has 617 and Polk 304. This is the lowest sinkhole exposure of any market we work in.

Hurricane exposure, measured
Across Ian, Nicole, Irma and Matthew the highest gust recorded at any Brevard land station was 81 mph. The station closest to Palm Bay peaked at 71 mph during Ian. Design speed is 150 mph.

NWS Melbourne post-storm reports. The 150 mph figure is a 700-year recurrence value, not a forecast.

Outside the HVHZ, which is not the same as unprotected
Brevard is not in the High Velocity Hurricane Zone, so none of the Broward and Miami-Dade product approval regime applies. That does not exempt you from opening protection, which is required here on other grounds.

FBC Section 202. Conflating the two is a common and expensive mistake.

The city is growing fast
Palm Bay added 18.2% to its population between 2020 and 2024, roughly three and a half times the rate of Brevard County as a whole, and it is the largest municipality in the county by both land area and population.

US Census Vintage 2024 estimates. At 86.67 sq mi it is the 10th largest incorporated place in Florida by land area, not the first or second as often claimed.

Rainfall
52 inches a year, measured at Melbourne International about six miles north of the city line. Moderate by Florida standards, though it lands on ground that drains badly.

NOAA NCEI 1991-2020 Climate Normals.

Flood insurance discount
Palm Bay holds a Community Rating System Class 7, worth 15% off National Flood Insurance Program premiums. The city has kept every floodplain review and elevation certificate issued since 1993.

The expensive surprises are in the ground, not the building

Most of Brevard County rates poorly for dwellings in the soil survey, and the reason is water sitting close to the surface rather than weak ground. That makes the pad elevation and the drainage plan the two line items most likely to move your budget. We price the dirt before we price the building.

What we build in Palm Bay

Every service we offer is available across Brevard County, from a shell kit you erect yourself to a finished home we hand you the keys to. What a build costs depends far more on the parcel than on square footage, so we price against your land rather than publishing a rate card.

What a build looks like

Three stages every Palm Bay project passes through, from a raw parcel to a finished home. Site work first, because that is where the budget is decided.

Where we build around Palm Bay

Brevard County and the rural land around it. The buildable acreage for a project this size usually sits outside the city limits, which is frequently what changes who issues your permit.

Building in Palm Bay: common questions

8 questions we get asked most often about building in Palm Bay. If yours is not on the list, ask it directly.

Start your project
What is the Compound, and should I buy land there?
It is nearly five thousand vacant quarter-acre lots across three subdivisions in southwest Palm Bay, platted by General Development Corporation in the 1960s. GDC went bankrupt in 1991 and development simply stopped. Today those 4,978 parcels are held by around 2,755 owners scattered worldwide, served by roughly 200 miles of ageing roads, with no water, sewer or electricity anywhere in the area, and the whole of it sits in a flood zone. That is why the land is cheap, and it is also the entire cost story. Before you buy, we would want to look at what it takes to get power to the parcel, whether the soil will take a septic system, and what the flood elevation does to your pad. The city is actively working on the area with EPA brownfields funding, so it is not abandoned, but nobody should buy there expecting a normal serviced lot.
How small a house can I build in Palm Bay?
That depends on your zoning, and it is the constraint that surprises people most. Palm Bay sets a minimum living area by district: 1,800 square feet in SRE, 1,600 in RE, 1,400 in RS-1, and 1,200 in GU, RR and RS-2. Only RS-3, at 800 square feet, allows a genuinely compact build. So the 900 to 1,100 square foot living core that a lot of barndominium buyers have in mind is non-compliant in every Palm Bay single-family district except one. Unincorporated Brevard County is easier on this, asking 750 square feet in its agricultural and general use districts. Check the zoning before you fall in love with a floor plan.
Can I have a tall shop bay for an RV?
Only in two districts, and it is worth knowing before you buy land. Palm Bay caps building height at 25 feet in RE, SRE, RS-1, RS-2 and RS-3. Only GU and RR allow 35 feet, and GU needs a five acre lot while RR needs an acre. A 14 foot door plus header plus track does not fit under 25 feet with any room to spare. Accessory buildings are capped again at the lesser of 25 feet or the height of the house, and a metal accessory building that does not meet the city design standards is capped at 12 feet. If a tall bay is central to your plan, we would look at GU or RR land, or at unincorporated Brevard where the residential limit is 35 feet.
Do I need impact windows in Palm Bay?
Yes, everywhere in the city, and the reason is worth understanding because it is counter-intuitive. Palm Bay stretches a long way inland from the Indian River Lagoon, so you might expect the requirement to stop somewhere in the middle. It does not. The code puts you in the wind-borne debris region either within a mile of the coast at 130 mph or anywhere the design wind speed reaches 140 mph. Palm Bay runs about 150 mph across the whole city, so the second test captures every parcel and the coastal test never even has to be considered. The 140 mph contour is nearly 30 kilometres beyond the far western city limit. There is no inland exemption here.
Can I put up the shop and live in it while I build the house?
No. Palm Bay prohibits it explicitly: no accessory building may be erected on a property without a principal building already present, and the accessory building may not be used until the house is fully constructed and has a certificate of occupancy. That rules out the staged approach a lot of people plan around. The way through is the same as elsewhere: permit the whole thing as the dwelling from the start and phase the interior finish instead. Worth adding that on a standard Palm Bay lot the shop cannot exceed the size of the house anyway. The one exception is RR-zoned land of two acres or more, which is the only route in the city to a shop bigger than the house.
What will the ground do to my budget?
More than in any other market we build in, and it is worth budgeting honestly. Around 88 percent of rated acreage in Brevard County rates Very Limited for dwellings in the USDA survey, the highest figure on our list. Every dominant soil in the county is poorly or very poorly drained, with a seasonal water table sitting roughly 18 to 30 inches below the surface, plus widespread ponding and flooding. What it is not is a bearing problem, so you are not looking at piles. You are looking at fill, pad elevation, possibly a stem wall, and engineered stormwater. On a raw Compound lot with a flood zone designation on top of that, the dirt is a substantial line item and we price it before we price the building.
Is Palm Bay a sinkhole area?
No, and this is one of the few places in Florida where that answer is clean. Brevard County has four reported subsidence incidents in the entire state database of 4,443, none of them verified as an actual sinkhole, which ranks it 46th out of the 60 counties that have reported anything at all. For scale, Hillsborough has 617 and Polk 304. None of Brevard four reports even falls within Palm Bay city limits. The geology explains it: thick sand and marine sediment over deep limestone, rather than the shallow karst that drives sinkhole activity in the middle of the state. Your soil report here is about the water table, not about voids.
How bad does the wind actually get?
Less than the 150 mph design number suggests, and it is worth putting those two things side by side. Across Ian, Nicole, Irma and Matthew, the strongest gust ever measured at a Brevard County land station was 81 mph at Cape Canaveral during Irma. The station nearest Palm Bay, about a mile off the southeastern corner, peaked at 71 mph during Ian. The 150 mph figure is not a forecast, it is a 700-year mean recurrence interval ultimate design value, which is what the code requires the structure to survive. Both facts are true and you should know both. The engineering is built to the code number; the storms you will actually live through will very likely be well under it.

Building in Palm Bay?

Start with the plan. Tell us what you want to build and we will draw it, then confirm what Brevard County will actually let you put on the parcel and what wind load it has to meet. That conversation costs nothing.
