Barred owls are particular about their real estate. They reject flimsy, undersized boxes and ignore perches that invite competing squirrels. A true barred owl bird house demands specific interior depth, a predator-resistant entrance, and a secure mounting strategy — or the cavity stays empty.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years studying bird-housing specifications, comparing material resistance data, and analyzing aggregated owner feedback for cavity-nesting owl species.
After breaking down build quality, dimensional accuracy, and real-world occupancy reports across seven models, this guide identifies which best barred owl bird house design actually persuades a territorial pair to roost, nest, and return season after season.
How To Choose The Best Barred Owl Bird House
Barred owls are secondary cavity nesters — they do not excavate their own holes. They rely on a box with the right volume, entrance diameter, and interior texture. Choosing wrong means a box full of squirrels or, worse, a box that never gets inspected at all.
Interior Height and Floor Area
A barred owl needs roughly 22 to 26 inches of interior height and a floor area of at least 11 x 11 inches. Shorter boxes crowd the female and reduce fledging success. Taller boxes allow deeper predator protection and give owlets room to climb interior kerfs toward the entrance.
Entrance Diameter — The Critical Cut
Barred owls require a 7- to 8-inch entrance opening. A 3-inch hole works for screech owls but completely blocks a barred owl. The entrance must sit at least 10 inches above the floor to keep newly hatched chicks from tumbling out and to prevent raccoons from reaching in.
No Perch, Predator Guard, and Drainage
A perch is a landing platform for raccoons, opossums, and house cats. The best boxes omit it entirely and rely on the owl’s talons gripping the rough exterior. An overhanging roof blocks rain from entering the hole, and drainage slots in the floor prevent moisture buildup that causes fungal infections in nestlings.
Material Longevity and Climate Fit
Natural cedar resists rot and splitting for 5 to 8 years without treatment. Recycled poly lumber lasts 15-plus years and never splinters or warps, but it is heavier and costs more. Exterior-grade plywood with linseed oil sits between the two — lighter than poly but less rot-resistant than cedar in persistently wet conditions.

In‑Depth Reviews
1. JCs Wildlife Recycled Poly Lumber Barred Owl Nesting Box
The JCs Wildlife Recycled Poly Lumber box is the longest-lasting option available for barred owls. Made from durable recycled poly lumber, it resists moisture, UV degradation, and woodpecker damage far better than any cedar or plywood box. Weighing 32 pounds, it feels substantial and requires a sturdy mounting point such as a large live tree trunk or a dedicated pole.
Interior dimensions of 15.5 inches wide by 24 inches tall provide ample room for a brooding female and growing owlets. The clean-out door on the side swings open easily for annual maintenance — a practical feature that also allows placement of a wildlife camera. Pre-drilled mounting strips and included screws simplify installation, though a second person is recommended due to the weight.
The box comes fully assembled — no DIY frustration. Pine shavings are included to make the cavity feel inviting from day one. The overhanging roof and the absence of a perch ensure predators have no easy handhold. For a decades-long investment that a pair of barred owls will actually use, this is the box to beat.
What works
- Poly lumber outlasts cedar by years with zero rot or splitting
- Side clean-out door with included shavings reduces maintenance headaches
- Fully assembled — no tools required for the box itself
What doesn’t
- Very heavy at 32 pounds — two-person mounting is mandatory
- Premium materials mean a higher initial investment than cedar models
2. JCs Wildlife Barred Owl House Nesting Box
This JCs Wildlife box strikes the ideal balance between functional design and reasonable cost. The exterior-grade plywood is treated with linseed oil to repel moisture, and the 26-inch interior height matches the dimensions barred owls instinctively seek. Interior kerfs — grooves cut into the front wall — give owlets the grip they need to climb toward the entrance when it is time to fledge.
The 13 by 13-inch floor area offers plenty of space for a full clutch, and the overhanging roof keeps rain from dribbling into the cavity. The side-swing clean-out door makes annual maintenance simple, and a bag of pine shavings is included to encourage immediate nesting. At 26 inches tall, the box is tall enough to deter raccoons from reaching the eggs.
Customer feedback consistently praises the build quality — reviewers note precise measurements, secure packaging, and positive occupancy reports within weeks of mounting. The linseed oil finish may require reapplication after 3-4 seasons in wet climates, but the overall value proposition is unmatched in this category.
What works
- Interior kerfs help owlets climb safely to the entrance hole
- 26-inch interior depth provides solid predator protection
- Pine shavings and side clean-out door included
What doesn’t
- Plywood may require periodic linseed oil re-coating in rainy regions
- Mounting requires reaching over the top for final screws — plan your ladder setup
3. GK-BAR Gamekeeper Barred Owl House
The GK-BAR Gamekeeper is one of the few mass-produced boxes designed specifically for barred owls rather than screech owls. Handmade in Michigan from weather-resistant cedar, it measures 22.5 inches tall with an 11.38 by 10.75-inch floor — a profile that fits the barred owl body size. The roof opens on a hinge for cleaning and interior access.
The mounting instructions recommend a height of 5 to 6 feet above ground — which is notably lower than the 12 to 15 feet most experts advise. Barred owls prefer higher cavity placements, so buyers may want to ignore that recommendation and mount it higher. The entrance hole size is correct for barred owls, though some owners have noted the hole can appear marginally tight for larger females.
Quality control has drawn mixed feedback. Some units arrive with perfectly aligned pre-drilled holes and tight joinery, while others show misaligned parts and cracked roof panels. The included instructions are minimal. Owners who add a small branch just below the entrance as a perch aid report faster occupancy — despite the general rule against perches, barred owls occasionally appreciate a landing spot.
What works
- Cedar construction resists rot and looks natural in wooded settings
- Hinged roof makes cleaning the interior straightforward
What doesn’t
- Inconsistent manufacturing — some units arrive with misaligned holes or cracked wood
- Mounting guide suggests 5-6 feet, which is lower than optimal for barred owls
4. Songbird Essentials SE519 Screech Owl House
The Songbird Essentials SE519 is a compact, well-built cedar box primarily intended for screech owls, American kestrels, and saw-whet owls. With dimensions of 9.5 inches wide by 15 inches tall, it is too small for a full-sized barred owl. However, it earns a listing here because barred owls in transition zones or heavily wooded suburban areas occasionally inspect this box for roosting rather than nesting.
The interior features a textured ladder surface that helps owlets climb — a thoughtful detail rarely found at this price point. The door swings upward, which can make wall-mounting awkward; you will want to pre-start the screws before climbing a ladder. The included mounting tips are species-specific and help orient the box correctly relative to sun and wind exposure.
Customer reports show frequent initial occupation by squirrels, but several owners documented screech owls moving in after 6 to 12 months. The cedar holds up well under seasonal rain, and the interior depth of 10.5 inches provides enough shelter for small raptors. For anyone specifically targeting barred owls, this box is too short — reserve it for smaller cavity nesters.
What works
- Interior ladder texture helps nestlings climb to the entrance
- Quality cedar construction with pre-drilled mounting holes
What doesn’t
- Only 15 inches tall — too short for barred owl nesting occupancy
- Upward-swinging door complicates mounting on a tree trunk
5. Woodlink OWL/Kestrel Screech House
The Woodlink OWL/Kestrel house comes fully assembled — a rare convenience that saves 30 to 60 minutes of building time. Made from natural inland cedar, it measures 13 inches wide by 19.75 inches tall with a 3-inch entrance hole. That entrance diameter is ideal for screech owls and American kestrels but is far too small for barred owls. This box is best viewed as a complementary unit for smaller cavity nesters near your primary barred owl box.
The included wood shavings are packed inside the box, and the front panel pivots open on screws for cleaning. Mounting hardware (Phillips head screws) is included, though several reviewers recommend replacing them with sturdier lag bolts for long-term security. The roof features a mortise-and-tenon joint that keeps water out — a simple but effective detail.
Customer reports are remarkably positive for a box in this range. Multiple owners note occupancy within 4 days of mounting, with screech owls, kestrels, and even red-bellied woodpeckers moving in. The lack of pre-drilled drain holes is a minor drawback — you may want to drill two small holes in the floor to prevent moisture accumulation during heavy rain seasons.
What works
- Comes pre-assembled — open the box and mount it immediately
- Mortise-and-tenon roof joint blocks water infiltration effectively
What doesn’t
- 3-inch entrance is species-correct only for small owls, not barred owls
- No factory drain holes; you should add them yourself
6. BestNest Premium Screech Owl & Kestrel House
The BestNest Premium house targets Eastern and Western screech owls, American kestrels, and saw-whet owls with a 3-inch recessed entry hole that blocks raccoon access. The interior measures 11 inches wide by 18 inches tall, offering more headroom than many comparable small-raptor boxes. The recessed entrance reduces light penetration, which helps the birds feel secure inside the cavity.
Construction uses manufactured sheet material rather than solid cedar — a detail that has disappointed some buyers expecting a solid-wood product. The design is thoughtful, with a top-hinged door secured by a screw and wingnut, vented bottom and side gaps, and sanded edges. However, there is no bottom screen for parasite control, and the material choice means the box may not last as long in persistently damp environments.
Owner feedback is split. Several users report successful occupation by kestrels and screech owls for multiple consecutive years. Others note that the listing’s display implies a two-box kit but only one box arrives — a presentation issue worth reading carefully before purchase. For barred owl purposes, the 3-inch entrance and 18-inch interior height are both well below what a barred owl requires.
What works
- Recessed 3-inch entrance helps deter raccoons and larger predators
- Hinged top door with wingnut closure simplifies annual cleaning
What doesn’t
- Manufactured sheet material is not solid wood — lower rot resistance
- Display may imply a two-pack; only a single box is included
7. 2PCS Carbonized Cedar Owl Houses
This two-pack of carbonized cedar boxes delivers incredible value for the budget-conscious birder. Each box measures 11.8 inches wide by 16.1 inches tall, with a 9.5-inch depth. The carbonized finish gives the wood a darker, weather-resistant surface that resists moisture and UV damage better than untreated cedar. The package includes wood shavings, a screwdriver, and all necessary hardware.
The entrance hole and interior dimensions are designed for screech owls rather than barred owls. The 16.1-inch interior height is too short for a barred owl to nest comfortably, but the two-box format makes this set ideal for placing multiple units around a property to increase overall raptor nesting opportunities. The ventilated side holes and waterproof roof design keep the interior dry.
Assembly is straightforward — several buyers describe it as a quick grandparent-grandchild project. Reviews consistently praise the sturdy feel and attractive appearance. For barred owl enthusiasts, these boxes work best as secondary units for smaller species while you invest in a dedicated taller box for the main target. The carbonized cedar will hold up for several seasons with minimal maintenance.
What works
- Two boxes per purchase — great for expanding cavity-nesting habitat
- Carbonized cedar resists weathering better than standard cedar
What doesn’t
- 16.1-inch height is too short for barred owl nesting
- Assembly required; not pre-assembled like some alternatives
Hardware & Specs Guide
Interior Height and Depth
Barred owls require a minimum 22-inch interior height to prevent raccoons from reaching eggs and to give owlets room to climb. Boxes shorter than 20 inches are generally occupied by smaller species such as screech owls or kestrels. Deep boxes also provide better insulation against temperature swings. Floor area should be at least 11 x 11 inches to accommodate a female and a full clutch of 2-4 eggs.
Entrance Diameter and Position
The entrance hole for barred owls should be 7 to 8 inches across — large enough for the owl’s body but small enough to exclude great horned owls. The hole should sit 10 to 14 inches above the floor. Higher placement reduces the risk of chicks exiting prematurely and makes it harder for predators to reach the nest contents.
Material Comparison — Cedar, Plywood, and Poly Lumber
Natural cedar offers 5-8 years of rot resistance with a natural appearance and light weight. Exterior-grade plywood treated with linseed oil sits in the middle — lighter than poly and less expensive, but requires periodic re-coating. Recycled poly lumber lasts 15-plus years, never rots or splinters, and holds up to extreme weather, but it is heavier and costs significantly more per unit.
Predator Guard and No Perch Rule
Every effective owl box omits an external perch. A perch gives raccoons, opossums, and snakes a foot-hold to reach the entrance. An overhanging roof that extends 2-3 inches past the front wall blocks rain from entering the hole. A recessed entrance — where the hole is set back from the front face — provides additional predator deterrence.
