In 2024 I tried six side hustles in twelve months. Five of them I quit. The sixth — storage hosting — has been quietly running for two years, has earned me €4,300 net, and has required maybe three hours of total work after the first day.
This isn't a "passive income" pitch. Most "passive income" content is lying to you about the unit economics or the time cost. This is the actual ranking, with the actual numbers, of what a normal Irish person can do with a spare hour and a small amount of capital. Storage came out on top for one specific reason that nobody else ever mentions.
1. Airbnb a spare room — the obvious one
Headline rate per night is huge: €60–€120 for a Dublin suburban spare room. Annualised at 60% occupancy: €13,000–€26,000. So why isn't everyone doing it?
Because the actual job is hospitality. You're cleaning between every guest. Restocking towels. Checking-in late arrivals. Replying to questions at 11pm. And the regulatory layer — Dublin City Council requires planning permission for short-term lets in non-PPR units, and the rules around 90-day annual caps are tightening every year.
Real time cost: 3–5 hours per booking turn. Net per hour: Around €25–€40. Real, but not passive.
2. Food delivery (Deliveroo, Just Eat, Bolt)
Headline rate: €13–€22 per hour at peak times in Dublin. Tax + bike costs + insurance and you're looking at €8–€14 net per actual hour. The job is honest but it's a job.
Real time cost: 100% — every euro is paid for an hour you worked. Net per hour: €8–€14. Useful for fast cash; never compounds; can't scale.
3. Dropshipping a Shopify store
Spent €380 on Facebook ads, €45 on a domain + Shopify, ~30 hours setting up, 12 weeks of evening optimisation. Net: €112 in sales, ~€480 in costs, broke even on revenue but lost the time. The case-study videos on YouTube don't show the 3-month learning loop or the Facebook ads-cost climbing year after year.
Real time cost: 80–120 hours before any revenue. Net per hour: negative for me; possibly €5/hr for a top-decile operator. The variance is brutal.
4. Freelance writing on Upwork / Reedsy
Headline rate: €30–€80 per hour for someone with a portfolio. The brutal part is unpaid hours: the writing itself is the easy bit; getting hired requires unpaid pitching, sample submissions, and revision cycles. My realised effective rate over 6 months was €18/hr.
Real time cost: 20–30 hours billable, 50% of that as unpaid sourcing/communication. Net per hour: €15–€25 if you're disciplined. Plateaus around €60/hr unless you specialise.
5. Parking-spot rental (driveway apps)
Renting a driveway near the Aviva or RDS for a match day: €25–€60 a day. I made €380 in one football season. Then the season ended.
Real time cost: Negligible. Net per hour: Very high during events, zero in the off-season. Real but bursty and capped at the number of event days near you.
6. Selling household stuff on Vinted
Decluttered to fund a holiday. Made €840 in 4 months. But the inventory is finite — once you've sold the stuff you don't need, it's over. And the time per item is real: photos, descriptions, replies, packaging, posting.
Real time cost: 30–60 minutes per item. Net per hour: €15–€25 while you have stock; zero when the wardrobe is empty.
7. Storage hosting — the one I kept
Single-car garage in Phibsboro at €145/mo. Two years and counting. Total time invested: 90 minutes for the listing setup (photos, description, ID verification), ~3 hours total across two years for two move-ins, six chat messages, and one renewal.
Net so far: €4,300 across 24 months. Effective hourly rate: Approximately €955/hr if you do the simple time-input math. That's not a real comparator — most of those hours weren't "work" but background availability — but it makes the point.
Why it works: every other option I tried converted my time directly into money. Storage converted my space into money. Space I already had. Space that was earning zero. Once the listing was live, the space was working 24/7 whether I was sleeping, on holiday, or busy with my actual job.
The honest caveats
It's not magic. Three things to know:
(1) Your space has to be acceptable. A wet, mouldy, spider-infested garage will not book. Spend €40 on a cheap sweep and a dehumidifier (the second one runs about €2/mo to power) and the listing rate doubles.
(2) The income is taxable. Net is roughly 60% of gross for a marginal-rate Irish taxpayer. Plan for that.
(3) The platform takes a fee. Packhood charges a small platform fee on each booking — necessary to fund the Host Guarantee, payment processing, and the people answering support emails when something breaks.
Within those caveats: it's the only side income I've ever had that gets quietly better with time and never asks for anything back.
How to start
Open the listing form. Photograph the empty space — five wide shots, lights on, floor visible. Write three sentences describing the suburb, dimensions, and one good feature. Set a price at the city median. Verify identity through Stripe Connect (~2 minutes).
Within 48 hours your listing is searchable. Within 2–4 weeks your first renter shows up. Then it just runs. The boring one wins.
