How Big a Barndominium Can You Build for Your Budget?
There are two answers here, and the second is the one that catches people. The first is arithmetic: a budget divided by a published cost band. The second is that nine of the counties on this site set a size below which the ordinance permits no house at all, which makes "how big can I build" and "how much of it is heated" the same question in Georgia.
Figures below are industry data from cited third-party sources, not a quote from Georgia Barndominium Builders. Every project is priced individually.
Bottom line up front
- At the mid-grade finished rate Barndominium.org publishes for Georgia, $200,000 buys roughly 1,650 to 3,050 square feet of finished home; an erected shell instead stretches the same money to roughly 4,000 to 6,650 square feet of unfinished structure.
- Nine counties on this site publish a minimum dwelling floor area, from Forsyth County's 700 sq ft to South Fulton's 1,800 on the ground floor, so there is a size below which you may not build a house at all.
- Where the ordinance measures heated floor area — Jackson, Newton, Paulding and South Fulton among them — an unheated shop bay counts for nothing toward that minimum, so a shop-heavy plan can fail a test the same building would otherwise clear.
Cost per square foot, by tier
The spread is wide because "barndominium" covers everything from a bare shell to a fully finished custom home. Tier is what actually explains the range, not location.

What actually moves the number
The living-to-shop split, which is the biggest lever on this page
Finished living space runs $65 to $120 per square foot at mid-grade in the Georgia figures published by Barndominium.org. An attached unfinished shop runs $15,000 to $40,000 per 1,000 square feet in I Love Pole Buildings' 2026 guide. Moving square footage from one to the other is the single largest change a buyer can make to what a fixed budget covers. In Georgia it also changes whether the dwelling is legal, which is why it gets its own section below.
Finish level, because interior work is nearly half the build
NAHB's 2024 Cost of Constructing a Home survey puts interior finishes at 24.1% of construction cost and major system rough-ins at 19.2% — 43.3% between them. That is where the gap between a shell and a finished home lives, and it is why the finish tier moves the square footage a budget reaches more than any other single decision.
Who is holding the contract
Two published sources looking at Georgia in the same month put a finished barndominium at $65 to $120 per square foot (Barndominium.org) and at $150 to $300+ per square foot (BuildMax). The gap is mostly scope. The lower band describes an owner-directed build off a kit where the buyer carries coordination, some labour and much of the risk. The upper band describes a single contract covering site work, foundation, utilities, engineering and finish.
Length is cheap, clear span is not
Adding bays down the long axis of a rectangular building extends a frame that is already sized. Widening the clear span steps the frame up, and frame weight climbs faster than the added floor area. Where more space is needed, a 30x50 or 30x60 usually costs less than a 40x40 for the same reason a longer building costs less than a wider one.
The parcel, which no per-square-foot figure includes
Clearing, fill, drainage, the length of the utility run and the septic system sit outside every number on this page. Barndominium.org's Georgia page gives $5,000 to $12,000 for a conventional gravity septic system and $15,000 to $30,000 or more for an engineered or alternative system. Our [site preparation](/services/site-preparation/) page covers what actually gets priced on a rural parcel.
What $200,000 buys, four ways
Division, not an estimate. Each row is $200,000 divided by a published cost band, and every one of them is building only — no land, no site work, no septic, no utility run, no fees.
Shell erected and dried in: roughly 4,000 to 6,650 sq ft
At the $30 to $50 per square foot band Barndominium.org publishes for an erected Georgia shell on your slab. This is a weathertight structure with frame, roof, cladding and exterior openings, standing on a foundation you paid for separately. It has no insulation to living standards, no interior partitions, no rough-ins and no finish, and it is not somewhere you can live yet. It is the number that makes barndominiums look impossibly cheap online. See barndominium kits for what is genuinely in the box.
Finished at mid-grade, owner-directed: roughly 1,650 to 3,050 sq ft
At the $65 to $120 per square foot band Barndominium.org publishes for a move-in-ready Georgia build with mid-grade finishes. This is the row most people mean when they ask the question. For scale, the Census Bureau puts the median size of a completed single-family home in 2025 at 2,142 square feet, so the middle of this band lands on a normal American house. It assumes the buyer is directing the project rather than handing over a single contract.
Finished at high-end: roughly 1,000 to 1,530 sq ft
At the $130 to $200 per square foot band from the same source. Worth saying plainly: at this tier a barndominium carries no cost advantage over conventional construction, so choose it because you want the building type. See luxury barndominiums for what that level of specification involves.
Finished under a full-service contract: roughly 670 to 1,330 sq ft
At the $150 to $300+ per square foot band BuildMax publishes for finished Georgia barndominium builds. This is more than double the mid-grade band above, from a source looking at the same state in the same month, and averaging the two together would hide the thing a buyer needs to see. The difference is scope: one figure describes buying a kit and running the job, the other describes buying a finished house under one contract that carries site work, foundation, utilities, engineering and finish.
The lever national guides skip: how much of it is heated
The honest answer to "how big for my budget" depends less on the budget than on the split between finished living space and unfinished shop. In Georgia that split does two things at once.
Shop space is genuinely cheaper, and here is the mechanism
Barndominium.org states it directly: shop and garage space "doesn't need insulation to living standards, HVAC, drywall, flooring, or any interior finish". NAHB's 2024 survey shows how large that omission is — interior finishes are 24.1% of construction cost and major system rough-ins are 19.2%, so a shop bay skips 43.3% of the build. It still takes its share of framing, exterior finishes and foundation, which is why it is not free. A slab thick enough to park on runs $6 to $10 per square foot on its own in I Love Pole Buildings' figures.
The same $200,000, split two ways
At the midpoint of the Georgia mid-grade band, about $92.50 per square foot, $200,000 covers roughly 2,160 square feet of all-living building. Take a 1,400 square foot house instead and add a 1,000 square foot shop at I Love Pole Buildings' $15,000 to $40,000, and the total is roughly $144,500 to $169,500 for a 2,400 square foot building — a bigger building, under budget. That is the lever, and it is why shop-heavy plans look so attractive on a spreadsheet.
And in Georgia the same move shrinks the number the county measures
That 1,400 square foot living side is exactly Jackson County's minimum under UDC 3-050(b). Trim it to 1,200 to buy more shop and the dwelling falls short there, because Jackson counts only heated space. The money saved is small, since the square footage moved is the cheap kind. This is the trade national content never states: in the counties that measure heated floor area, the cheapest square footage in the building is also the square footage that does not count.
Which counties this applies to, by name
Forsyth, Dawson, Newton, Paulding, Jackson and South Fulton all state their minimum on heated floor area, and Jackson is the one that publishes the definition excluding garages and unheated basements. Bartow's Sec. 10.1.2 says heated living space. Walton's 1,400 sq ft is written as primary dwelling floor area and Coweta's 1,725 sq ft as floor area per unit, so the way those two treat an attached shop is confirmed with the county rather than assumed from a neighbour.
Where the shop is genuinely the point
Three honest answers. Grow the building down its long axis, which is the cheap direction anyway. Put the shop in a separate detached building, which in several counties is the cleaner permitting route. Or step up to a footprint that carries a real shop without eating the house — see 40x60 barndominiums, where a 2,400 sq ft building still fails Jackson's minimum at a 1,000 living and 1,400 shop split.
Georgia's legal floor, before your budget gets a say
This is the part that inverts the usual advice. In most of the country the question is how much house your money buys. In several Georgia counties there is a house size below which you may not build at all.
Coweta County: 1,725 sq ft per unit
Coweta County's Appendix A, Article 23 dimensional requirements set a minimum floor area per unit of 1,725 sq ft in the RC Rural Conservation district and across its rural residential types, on a five-acre minimum building lot. Priced at the top of the published Georgia mid-grade band that is $207,000 of dwelling — the entire budget in this guide's headline question, spent on the smallest house the county permits. More on Coweta County.
South Fulton: 1,800 sq ft on the ground floor, or 2,000 total over two storeys
South Fulton's AG-1 Table 4-1 requires 1,800 sq ft of heated floor area on the ground floor for a single-storey dwelling, and 2,000 sq ft total with 1,200 sq ft on the ground floor at two or more storeys. This is a real divergence from the old Fulton County AG-1 rule, which stated there was no minimum heated floor area in the district, so anyone working from Fulton precedent has the wrong number. More on South Fulton.
Jackson County: 1,400 sq ft heated, for barndominiums specifically
Jackson County regulates the building type by name. UDC 3-050, "Barndominium dwelling, single-family detached", adopted by Ord. No. 21-009 on 20 December 2021, requires "a heated gross floor area of at least 1,400 square feet". It also permits the use by right in only three districts — PCFD, A-2 and AR — while an ordinary detached single-family dwelling is permitted in most. There are Jackson districts where you may build a house but not a barndominium. More on Jackson County.
Bartow County: 1,200 sq ft, and no later addition to reach it
Bartow County Zoning Ordinance Sec. 10.1.2 requires not less than 1,200 square feet of heated living space, and adds that "an existing structure may not include an addition to fulfill the minimum square footage". The compliant area has to be there in the dwelling as built. Bartow also sets a minimum 5:12 roof pitch under Sec. 10.1.4, which many stock kits quoted at 2:12 or 4:12 do not meet. More on Bartow County.
The two inversions: Paulding and Newton
Both put the smaller minimum house on the larger minimum lot, which is the opposite of what a buyer assumes. Paulding County's A-1 agricultural district has a five-acre minimum lot and asks 1,100 sq ft of heated living area; R-1 rural residential has a one-acre minimum lot and asks 1,600. Newton County's A district has a ten-acre minimum lot and asks 1,000 sq ft heated; RE and AR ask 1,800. The cheap-land district is the one with the small-house allowance. See Paulding County and Newton County.
Where the floor barely binds
Forsyth County's Table 15.2 sets 700 sq ft of heated floor area per dwelling unit in both A1 and AG-Res, and Dawson County sets 800 sq ft in RA, RRE and RSR. A budget that struggles in Coweta has substantial headroom in either. One caution on Forsyth: its 2,000 sq ft minimum home size applies only to a major subdivision built under the large-lot incentive route, not to a single house on an existing A1 parcel. See Forsyth County.
Why a bigger shell costs less than people expect
The frame is a smaller share of a finished house than almost anyone guesses, which is why buying more building now is cheaper than buying more house later.
Framing is 16.6% of construction cost
NAHB's 2024 Cost of Constructing a Home survey puts framing at 16.6% of total construction cost, down from 20.5% in 2022 — the largest percentage-point decrease of any stage between the two surveys. Add exterior finishes at 13.4% and the structure and envelope together are about 30% of the build. Interior finishes and rough-ins are 43.3%.
The Georgia cost bands say the same thing independently
An erected shell at $30 to $50 per square foot against a finished home at $65 to $120 puts the shell at roughly a third of the finished total. Two different methods, published by different people, landing in the same place is a reasonable sign the number is real.
What that means at the moment you are choosing a size
Adding ten feet of length to a rectangular building adds frame, roof, slab and cladding, and adds no interior finish at all if the added bay stays unfinished. That is the cheap 30% side of the ledger. Widening the clear span is the expensive direction, because clear-span width drives frame weight faster than anything else. Where more space is needed, going longer beats going wider.
The caveat that keeps this honest
Cheaper per square foot is not cheap. A larger shell still needs a larger slab, a larger footprint of site work and a larger disturbed area. And it does not move the dwelling past a county minimum unless the added space is heated, which is the whole point of the section above.
Finish later: the strategy, and where it runs out
Buy more shell now, finish the interior over several years. The arithmetic supports it. Two Georgia constraints have to sit alongside it.
The arithmetic genuinely works
$200,000 buys roughly 4,000 to 6,650 square feet of erected shell against roughly 1,650 to 3,050 square feet of finished home at mid-grade rates. For a buyer who intends to do interior work themselves over time, that is a real path and not a trick of presentation. It is also a multi-year path, and it should be planned as one.
Bartow County Sec. 18-129 puts a six-month clock on a dried-in shell
It is unlawful in Bartow to leave a residential structure "in a partially-built status for more than six months with no substantial progress occurring on the construction", and "partially-built" expressly includes buildings "that have been framed or dried-in (siding, roofing, windows and doors in place) but not completed". It is separately a violation for a partially completed building to sit without a certificate of occupancy more than 30 days after its permit expires. Bartow enforces this by citation and nuisance abatement. Under Sec. 18-168 a permit also becomes invalid unless the work is completed within 12 months of issue, with extensions of up to 12 months available.
And in Bartow the later half cannot count toward the minimum
Sec. 10.1.2 states that "an existing structure may not include an addition to fulfill the minimum square footage". So the finish-later plan cannot be used to reach Bartow's 1,200 sq ft. Anywhere a minimum bites, the compliant heated area is planned from day one rather than staged.
Lending treats a shell differently from a house
A conventional mortgage funds a finished, habitable dwelling, and an unfinished shell is not one. That changes which of the rows in the first section a buyer can actually reach with borrowed money rather than cash. The financing route is its own subject and it is worth resolving before a size is chosen.
Reading this because you are weighing a build? The next step is a plan drawn for your program.
What's different about Georgia
Nine counties on this site publish a minimum house size, and they span 2.5x
Forsyth County sets 700 sq ft of heated floor area per dwelling unit. Dawson County sets 800 in RA, RRE and RSR. Newton County sets 1,000 in A and 1,800 in RE and AR. Paulding County sets 1,100 in A-1 and 1,600 in R-1. Bartow County sets 1,200. Walton County and Jackson County both set 1,400. Coweta County sets 1,725. South Fulton sets 1,800 on the ground floor of a single-storey dwelling. Same state, same money, different smallest legal house — decided by which county line the parcel sits inside.
Jackson County counts only heated space, and says so in writing
Jackson County UDC 3-050(b) requires a barndominium to provide "a heated gross floor area of at least 1,400 square feet", and UDC 105 defines building floor area as the gross floor area of all heated spaces, adding that heated floor area "does not include garages, unheated basements, attic storage areas or partially enclosed decks or patios". So an unheated shop bay contributes nothing toward the minimum. A 30x40 split 800 living and 400 shop reads to Jackson as an 800 sq ft dwelling and falls short of a line the full 1,200 sq ft would have cleared.
In Coweta and South Fulton the legal minimum can consume a $200,000 budget on its own
Coweta County requires 1,725 sq ft per unit. South Fulton requires 1,800 sq ft on the ground floor of a single-storey dwelling in AG-1. At the top of the $65 to $120 per square foot Georgia mid-grade band published by Barndominium.org, those floors price at $207,000 and $216,000 — before land, site work, septic, utility runs or permit fees, and before a single square foot of shop. In Forsyth County the same budget reaches nearly three times that county's floor.
South Fulton writes the two-storey answer into the ordinance
South Fulton's Table 4-1 requires 1,800 sq ft on the ground floor at a single storey, but only 1,200 sq ft on the ground floor at two or more storeys with 2,000 sq ft total. Going up rather than out is an explicit route there, and it is the one county on this list where the ordinance itself offers it. Whether a loft or second floor counts toward the minimum in Jackson, Walton, Coweta or Bartow is confirmed with each county before a plan is committed to. See two-storey barndominiums.
Bartow County closes the finish-later route from both ends
Bartow County Code Sec. 18-129 makes it unlawful to leave a residential structure "in a partially-built status for more than six months with no substantial progress occurring on the construction", and says "partially-built" expressly includes buildings "that have been framed or dried-in (siding, roofing, windows and doors in place) but not completed". Separately, Zoning Ordinance Sec. 10.1.2 states that "an existing structure may not include an addition to fulfill the minimum square footage". So in Bartow the shell cannot sit indefinitely, and later additions cannot be used to reach the 1,200 sq ft minimum.
Two Georgia counties charge the permit on the same heated split
Jackson County permits heated space at $0.20 per sq ft and unheated at $0.10. Newton County charges $0.25 heated and $0.15 unheated. Those counties measure the heated-to-unheated line twice — once to decide whether the dwelling meets the minimum, once to price the permit — and the two pull in opposite directions. Adding shop lowers the permit fee and lowers the number that has to clear the minimum.
Pros and cons, honestly
Pros
- At mid-grade Georgia rates, $200,000 reaches roughly 1,650 to 3,050 sq ft of finished home, and the Census Bureau puts the median completed single-family home in 2025 at 2,142 sq ft.
- Unfinished shop space skips the two most expensive stages of a build — interior finishes at 24.1% and rough-ins at 19.2% of construction cost in NAHB's 2024 survey.
- Framing is 16.6% of construction cost, so buying a longer building now costs much less than the added floor area suggests.
- Lengthening a rectangular building adds bays to a frame already sized for the span, which is cheaper than widening it.
- Forsyth County's 700 sq ft floor and Dawson County's 800 sq ft leave a modest budget real headroom, and both are agricultural or rural-residential districts with land to match.
Cons
- The shell-only figure is not a habitable house, and reading it as what a budget builds is the most common way these numbers get misused.
- In Coweta County and in South Fulton AG-1, the smallest dwelling the ordinance permits can absorb a $200,000 budget on its own at the upper end of the published Georgia band.
- In Jackson, Newton RE and AR, Paulding R-1 and South Fulton, an unheated shop bay counts for nothing toward the minimum, so a shop-heavy plan can fail a minimum the same building would otherwise clear.
- Two published Georgia sources put a finished build at $65 to $120 and at $150 to $300+ per square foot, so any single figure taken from one of them alone can be off by more than double.
- Bartow County makes it unlawful to leave a home framed or dried-in for over six months with no progress, which constrains the finish-later plan there.
- Land, site work, septic, utility runs, engineering and permit fees sit outside every figure on this page.
