Chicken Coop Building Cost Calculator
Estimate the materials cost of building a DIY chicken coop and run. Adjust size, quality, and materials to find a build that fits your budget.
How much does it actually cost to build a chicken coop?
For a build using new materials at 2026 US prices, a 24 sq ft coop with a 60 sq ft run lands in one of three bands depending on quality:
- Basic (OSB, plastic roof): about $1,335
- Standard (plywood, shingles): about $1,785
- Premium (cedar, metal roof): about $2,565
Drop the run and the coop alone runs roughly $745, $1,195, or $1,975 across the same three tiers. These are materials only. Labor adds $400-$1,200 if you hire a carpenter. The sub-$500 figures common in older guides almost always assume salvaged or pallet materials rather than new stock — which is a legitimate way to build, just not the same comparison.
Materials cost by build quality
These totals come straight from the calculator at its default settings: a 24 sq ft coop, new materials at 2026 prices, plastic-panel roof, two nest boxes, roost bars, paint, and the run fenced in half-inch hardware cloth. Switch to metal roofing or cedar framing and the numbers climb; switch the run to chicken wire and the coop-plus-run figure drops by about $338, for reasons the next section explains.
| Build quality | Coop only (24 sq ft) | Coop + 60 sq ft run |
|---|---|---|
| Basic (OSB, plastic roof) | $744 | $1,336 |
| Standard (plywood, shingles) | $1,193 | $1,786 |
| Premium (cedar, metal roof) | $1,974 | $2,567 |
The run is not a rounding error: on these defaults it adds about $593 in every tier, which is roughly half the cost of a standard coop again. It lands the same across tiers because mesh and run framing do not care how the coop is built — a 2x4 and a roll of hardware cloth cost what they cost. Set your own size, quality, roof and mesh in the calculator above to get a figure for your exact plan.
What drives coop build costs
A few line items account for most of the budget. The calculator itemizes the exact figures, but the pattern is consistent:
- Structural lumber for the floor, walls, and roof framing is usually the single largest line, often 35-45% of a basic build.
- Run fencing and run framing together often rival the coop itself. A 60 sq ft run needs roughly 186 sq ft of mesh for the walls alone, and about 246 sq ft once the top is covered — which is the figure the calculator uses, since an uncovered run is not predator-proof.
- Sheathing for the walls and floor. As of mid-2026 a 4x8 sheet of 7/16" OSB lists around $14-$22 depending on retailer, 23/32" CDX sheathing around $39, and 3/4" plywood around $70. Our per-square-foot rates sit above the bare sheet price because they also carry fasteners, offcuts and the pieces you cut wrong.
- Roofing, from about $1 per sq ft for plastic panels to about $3.50 for metal.
- Hardware: hinges, screws, and predator-proof latches. Budget at least $75-$100, because cheap latches get opened by raccoons.
Chicken wire vs hardware cloth
Chicken wire is cheap, but raccoons pull it apart and rats chew through it within weeks. Most keepers who start with chicken wire end up rebuilding with hardware cloth after their first predator loss. Use 1/2-inch 19-gauge hardware cloth from the start. On the calculator’s default 60 sq ft run the difference is about $338 — more than the “$100-$200” often quoted, because a covered run needs mesh on five sides rather than four. It is still far less than rebuilding after an attack, and the calculator now defaults to hardware cloth for that reason.
Two things follow from that, and they are the most common regrets in build write-ups. The run tends to cost more than people budget for, because mesh is priced by area and a covered run needs mesh on five sides rather than four. And chicken wire is a containment material, not a predator barrier — it keeps chickens in, and keeps almost nothing out.
DIY vs prefab
Prefab is faster and needs no carpentry skills. The downsides are real, though: capacity labels are commonly inflated by 30-50%, hardware quality tends to be lower, and the sizes rarely match what the Coop Size Calculator says your flock actually needs.
- DIY makes sense for: 6+ birds, specific size requirements, a 10+ year lifespan goal.
- Prefab makes sense for: 2-4 birds, renting, no tools, wanting chickens this weekend.
Common mistakes that inflate costs
- No plan before buying. This leads to wrongly-cut lumber and repeat trips to the store. Chicken coop plans gives four sizes with the full cut list and sheet count for each.
- Underestimating run fencing. Most builders forget the run needs a roof too.
- Untreated lumber touching soil. It rots in 2-5 years. Use pressure-treated for all ground contact.
- Cheap latches. Raccoons open hook-and-eye latches. Use locking barrel bolts.
- No ventilation budget. High wall vents need hardware-cloth covers and weather lips.
What this estimate assumes, and what it leaves out
Four assumptions are baked into the arithmetic, and each one moves the number if your build differs.
- A square footprint. Perimeter is calculated as the square root of the floor area times four, which is the smallest possible perimeter for a given area. A long, narrow coop of the same square footage needs more wall framing, more sheathing and more fencing than quoted.
- A shallow roof. Roof area is floor area plus 10 percent, which suits a gentle slope or a lean-to. There is no pitch input, so a steep gable adds materially more surface than this allows — a 12/12 pitch is roughly 40 percent more roof than its footprint.
- A 10 percent contingency, not a cutting allowance. It is applied to the whole subtotal, including hardware, nest boxes and paint, which is why we call it a contingency rather than waste: you do not waste a tenth of a box of hinges. Trade estimating guides typically allow 10–15 percent on lumber and sheet goods specifically, so on a cut-heavy build ours sits at the low end.
- No tools. Materials only. If you do not already own a circular saw, a drill and a square, add $150–$300 for the cheapest usable versions — and note that a first-time builder buying tools has not saved money against a prefab on build one, only on build two.
Permits are worth a call before you buy anything. Coops under about 100–120 sq ft often fall below the threshold that triggers a building permit, but that varies enormously by jurisdiction and setback rules apply almost everywhere regardless of size. This calculator will happily size a 200 sq ft coop, which is well into permit territory in most places.

Frequently asked questions
How much does it cost to build a chicken coop?
Using new materials at 2026 prices, and fencing the run in half-inch hardware cloth as we recommend, a basic 24 sq ft coop with a 60 sq ft run runs about $1,335. Standard quality is around $1,785 and premium cedar around $2,565. Without the run, the coop alone is roughly $745, $1,195, or $1,975 across those three tiers — the run adds about $593 whichever tier you pick, because mesh and run framing cost the same regardless of how the coop itself is built. Salvaged or pallet materials can cut a basic build to $150-$300. Labor adds $400-$1,200 if you hire out.
What is the cheapest way to build a chicken coop?
Use reclaimed lumber, OSB sheathing, plastic roofing. One place not to cut costs: run fencing. Cheap chicken wire gets replaced after the first predator attack.
Is it cheaper to build or buy a chicken coop?
For 2-4 birds, a prefab may cost similar to DIY. For 6+ birds, DIY is usually 20-40% cheaper than a comparable-quality prefab, and it lets you build to the size your birds actually need.
How long does it take to build a chicken coop?
A 24 sq ft coop takes an experienced DIYer a weekend (12-16 hrs). First-timers should budget 20-30 hrs. Walk-in coops add 8-12 hrs.
Do I need a permit to build a chicken coop?
Depends on your municipality. Coops under 100-120 sq ft rarely need permits, but setback rules almost always apply. Check local zoning before building.
What wood is best for a chicken coop?
Pressure-treated for ground contact. Cedar or redwood for exterior siding if budget allows. Standard 2x4s for framing. 3/4-inch exterior plywood for sheathing. Never leave OSB exposed to weather without paint or cladding.
How much should the run cost compared to the coop?
Closer than most people expect. At this calculator’s defaults a 60 sq ft run in half-inch hardware cloth adds about $593 whatever the coop tier — roughly half the cost of a standard coop again. It is the same figure across tiers because mesh and run framing are priced by what they are, not by how the coop is built. Drop to chicken wire and the run costs about $255 instead, which is exactly the saving that gets undone by the first raccoon. The figures assume you cover the top of the run, which you should: climbing predators are the usual reason an uncovered run fails.
Can I build a chicken coop cheaply from pallets?
Yes, and it is the main way people get a build under $300. Free pallets, marketplace lumber, and a salvaged door can bring a basic coop down to $150-$300 in materials. The trade-off is time and consistency: pallet wood varies in size and condition, and you still want new hardware cloth rather than salvaged wire. On treatment, pallets in international trade carry an IPPC mark under ISPM 15 showing how the wood was treated — HT means heat treatment, MB means methyl bromide fumigation. Prefer HT. Methyl bromide is an ozone-depleting fumigant being phased out under the Montreal Protocol, banned for this use in the EU since 2010 and largely out of US use since 2005, so MB-stamped pallets are now uncommon rather than a routine hazard — but the stamp is easy to check and worth checking.
Sources
The honest headline first: no extension service publishes coop build costs. Several publish free plans, and at least one includes a bill of materials — but they give quantities, not dollars. So every cost figure on this page is ours, checked against current retail listings rather than derived from research. The sources below are price references and construction plans, cited as such.
- Coop plans and bills of materials (no costs): LSU AgCenter — Poultry Building Plans. Free downloadable construction plans from 4′×9′ backyard houses upward, including one with a bill of materials for a brooder house. Useful for quantities and dimensions; contains no pricing whatsoever, which is precisely why our dollar figures cannot be sourced to an extension service. See also Poultry Extension — “Housing Design for Small and Backyard Poultry Flocks” for design guidance.
- Sheet-goods prices (retail listing, not research): Woodworking Advisor — Lowe’s 4×8 Plywood Prices, updated July 2026. 7/16" OSB sheathing $18–$22 a sheet ($0.30–$0.56/sq ft), 23/32" CDX sheathing $39.00 ($1.22/sq ft), 3/4" plywood $69.85–$74.98 ($2.18–$2.34/sq ft). Independent listings put 7/16" OSB lower again — Sutherlands at $12.99 and Tart Lumber at $14.10 — so treat $14–$22 as the realistic spread rather than a single price.
- Waste and contingency allowances: I AM Builders — “How to Calculate Lumber Quantities for Residential Framing”. An estimating guide rather than research, but it is specific where most are vague: studs 10 percent, plates 5 percent, joists 10 percent, rafters 10 percent, LVLs and beams 5 percent, wall and roof sheathing 10–12 percent, and “small, chopped-up walls with tons of openings” 15 percent. Notably it puts hardware at 3–5 percent, not 10 — which is the clearest argument that our flat 10 percent across every line is a contingency rather than a cutting allowance. A coop is a small, opening-heavy structure, so on the framing and sheathing lines our 10 percent sits at the bottom of what this guide would allow.
- Pallet treatment stamps: ISPM 15, the international standard behind the IPPC mark. HT denotes heat treatment to a core temperature of 56 °C for at least 30 minutes; MB denotes methyl bromide fumigation, an ozone-depleting treatment being phased out under the Montreal Protocol.
What is ours rather than published: every cost constant in the model — framing at $3.50/$5.50/$10.00 per sq ft, sheathing at $1.20/$2.00/$2.80, roofing at $1.00–$3.50, fencing at $0.50/$1.75/$2.50, hardware, nest boxes, roosts and paint. None is a published rate; each bundles material, fasteners and offcuts into a single per-square-foot figure, which is why they sit above bare sheet prices and cannot be checked against them directly. Also ours: the square-footprint assumption, the 1.1 roof multiplier, the 10 percent contingency, the prefab base ranges ($150–400 / $400–750 / $750–1400) and the linear scaling behind them, the $400–$1,200 labour figure, and the build-time estimates (12–16 hours experienced, 20–30 first-timer). The currency rates are fixed and undated.
