Hide Parcels on Front Porch (Hidden Box DIY)
A discreet parcel cabinet can keep deliveries out of sight without blocking your porch. Start by measuring the door, landing, route, and parcels you expect. A 24 × 18 × 18-inch cabinet is a useful design target, not a code rule. Keep it clear of the required landing, build it to shed water, and anchor it to sound material.
A homemade parcel box can cost less than a ready-made cabinet, and you can size it to fit your porch. The trade-off is that you must plan for weather, access, and safe installation. A box that hides packages but blocks the door or leaves parcels wet has missed the point.
I start with the porch, not the saw. That small step helps avoid the most common problem: choosing a spot that looks clear with the door shut but interferes with the landing or swing once the door opens. The guidance below helps you plan a practical hidden parcel box and check it before use.
Planning: Measure the Porch, Door, and Parcel Envelope
A parcel envelope is the largest package size you want the cabinet to hold. Measure the porch and the parcels before choosing a cabinet size. This avoids building a box that is too small or taking up more porch space than needed.
Measure the door width, the landing, nearby steps, and the route people use to reach the door. Note the door’s swing and any handles or trim that extend into the space. Then measure a few typical deliveries, including the largest parcel you can reasonably expect.
A useful starting target for the cabinet is 24 inches wide × 18 inches deep × 18 inches high. This is a design target, not a code minimum or a guarantee that every parcel will fit. Check the inside dimensions too: the walls, lid, and supports reduce usable space.
| Parcel cabinet choice | Best fit | Main trade-off |
|---|---|---|
| Small box, about 18 × 14 × 14 in. | Limited porch space and small parcels | Larger deliveries may not fit |
| Starting target, 24 × 18 × 18 in. | A range of everyday parcels | Needs careful clearance checks |
| Larger custom box | Oversize deliveries | Takes more space and may affect access |
Dimensions above are exterior design examples, not standard parcel sizes. If the porch is tight, measure the usable footprint with tape on the ground before buying materials. Check local building rules, historic-district rules, HOA terms, and lease conditions if they apply. Next, confirm that the proposed location works with the door open.
Measure parcels before setting the box size
Parcel measurements should include the full outer package, not just the item inside. Allow a little extra room so a carrier can place a box without forcing it through a narrow opening. Consider whether a package could be laid flat and whether the lid can close with the parcel inside.
Access and Clearances: Preserve the Landing, Route, and Door Swing
A landing is the level area at a doorway that provides a place to stand and move through the door. The cabinet must not take up required landing space or stop the door from opening. Check the rules adopted where you live, since local editions and amendments can differ.
Under the 2021 International Residential Code (IRC) §R311.3, an exterior-door landing generally must be at least as wide as the door it serves and 36 inches deep in the direction of travel. Exceptions and local changes may apply. The 36-inch depth is not a general setback rule for every porch object; ask your local building department how the rule applies to your door and landing.
Mark the cabinet footprint with tape or a cardboard mock-up. Open the door fully and walk the route as a visitor or carrier would. The box should not sit on stairs, intrude into the required landing, hinder door operation, or narrow an applicable accessible route.
A cabinet may appear clear when the door is closed yet overlap the landing once you account for how people approach the threshold. Check the full path, not just the space directly in front of the door. If there is no suitable location on the porch, do not solve the problem by placing the box on a step or in a walkway.
Delivery access matters too. A hidden box only works if carriers can find and open it. Give clear delivery instructions, and check the carrier’s rules before relying on a lock or access code. Keep the box visible enough to identify while screening its contents from casual view.
Execution: Build, Weatherproof, and Anchor the Cabinet
A weather-resistant cabinet sheds rain, limits water entry at its lid, and gives any trapped moisture a way out. It also needs a secure attachment to suitable material. No single fastener or anchor works for every porch, so match the hardware to the actual structure.
Use 3/4-inch plywood rated for exterior use for the cabinet body. Seal cut edges, then apply a finish suitable for outdoor exposure. “Exposure 1” plywood is intended for limited weather exposure during construction; it is not a substitute for panels rated for permanent exterior use.
Build a lid that sheds water
The lid should slope toward the outside, away from the house and door threshold. Fit a continuous exterior-rated gasket where the lid meets the cabinet. Provide a drain path at the lowest exterior point so water that gets inside can escape without running toward the building.
Use corrosion-resistant hinges and hardware suited to outdoor exposure. Plan the opening so a carrier can place a parcel inside without lifting a heavy lid awkwardly. A latch or lock can add control, but only use one that delivery workers are permitted and able to operate.
Seal the plywood edges and fastener holes as part of the finish work. Check the lid for a close fit, but do not rely on the gasket alone to keep rain out. The slope and drainage path are important parts of the design.
Anchor to the real structure
Choose anchors for the actual substrate: framing, masonry, or concrete. Do not fasten only to thin siding, trim, or unsupported cladding. Follow the fastener maker’s instructions and use its published allowable-load information for the material and installation conditions.
There is no universal safe anchor count or load rating for every porch. The right hardware depends on what lies behind the surface, the edge distances, and how it is installed. If you cannot identify the structure or are unsure how to anchor it, ask a qualified installer rather than guessing.
Compare Cabinet Locations Before You Build
A location is suitable only if it hides parcels while preserving access to the door and route. Compare the likely spots with the door fully open and the landing marked. A convenient corner is not a good choice if it blocks a required clear area.
| Possible location | Check before choosing it | Avoid if |
|---|---|---|
| Beside the door | Door swing, landing width, and carrier reach | It overlaps the landing or blocks the door |
| Along a porch wall | Route width and access to the box | It narrows a route that must remain clear |
| Near porch steps | Safe walking path and parcel handling | The box sits on a stair or obstructs the steps |
| Away from the entrance | Clear delivery directions and weather exposure | Carriers may not find it or it is hard to reach |
Use a cardboard mock-up at the proposed size. Walk past it, open the door, and check whether someone can approach and use the box without stepping around an obstruction. This quick test can reveal a poor location before you cut any plywood.
Practical Layout Examples
These are planning examples, not reports of named homes or measured installations. They show how I assess common porch layouts: first protect the door area, then decide whether a parcel cabinet can fit elsewhere without making delivery harder.
A narrow porch with an inward-swinging door: Mark the full landing and door movement before setting a cabinet. If a box at the side would overlap that space, reduce the cabinet size only if it still fits intended parcels, or look for another permitted location. Do not force the larger design target into a tight porch.
A deeper porch with a side wall: A cabinet beside the wall may work if the door opens fully and the approach remains clear. Test the location with a parcel inside, too. The lid should open for a carrier, and the parcel should be retrievable without moving the cabinet or blocking the entrance.
In both layouts, confirm delivery instructions before relying on the box. A hidden cabinet is useful only when the carrier knows where it is and can use it.
Verification: Test Delivery Access, Drainage, and Retrieval
A final check is a simple test of how the cabinet behaves in place. Open the door fully, use the lid, and retrieve a parcel. Then inspect the drainage and anchorage. This can catch problems that were easy to miss during the build.
Before regular use, check that:
- The door opens fully and the required landing and route remain clear.
- A carrier can find and operate the box using your delivery instructions.
- The lid closes against its gasket without binding.
- Water can drain at the lowest exterior point, away from the house and threshold.
- The cabinet feels secure, and the anchors are installed as directed for the substrate.
- A parcel can be placed inside and removed without blocking the entrance.
After rain, look inside for water and check that the drain path is open. Recheck the cabinet if it shifts or if the porch surface or finish changes. If the box no longer sits securely or begins to interfere with access, stop using it until you correct the issue.
Conclusion: Make Concealment Work With Access
A well-planned parcel cabinet can screen deliveries and keep them together, but it should never take priority over safe entry or required clearances. Measure first, check local rules, choose exterior-rated materials, and anchor to the structure rather than the surface covering.
Before building, confirm the cabinet fits your parcels and the porch. Before using it, test the door, route, lid, drainage, and delivery instructions. If any check fails, move or resize the cabinet rather than accepting an obstruction.
Frequently Asked Questions
How big should a front-porch parcel box be?
A useful starting target is 24 × 18 × 18 inches, measured outside. Choose the final size after measuring your parcels and checking porch clearances.
Can I put a parcel box on the door landing?
Do not place it where it intrudes into a required landing or interferes with the door. Check the code edition and amendments adopted by your local building department.
What is the required exterior-door landing size?
The 2021 IRC §R311.3 generally calls for a landing at least as wide as the door and 36 inches deep in the direction of travel. Exceptions and local amendments may apply.
Can I place the box on a porch step?
No. Keep it off stairs and out of the walking path. Choose another location that preserves safe access to the entrance.
What plywood should I use for a DIY parcel cabinet?
Use 3/4-inch plywood rated for exterior use. Seal cut edges and finish it for outdoor exposure; Exposure 1 sheathing is not a substitute for permanent exterior-rated panels.
How do I keep rain out of the box?
Pitch the lid toward the outside, add a continuous exterior-rated gasket, and provide a drain path at the lowest exterior point. Do not direct water toward the house or threshold.
How should I anchor a parcel cabinet?
Choose corrosion-resistant anchors for the actual substrate and follow the manufacturer’s installation instructions. Do not rely on thin siding, trim, or an advertised load figure alone.
Should I lock the parcel box?
Only if the delivery service allows it and carriers can use the lock. Confirm the carrier’s requirements and provide clear instructions before relying on a locked box.
What if my porch is too small for the box?
Do not put it on a step or in the landing to make it fit. Consider a smaller cabinet that still meets your parcel needs or another permitted delivery arrangement.
