If you have a spare room in Dublin, you've been told the answer: rent it out under the rent-a-room scheme, take €14,000 a year tax-free, retire at 50. The numbers look unbeatable on paper.
On paper. The actual lived experience of a rent-a-room arrangement is something else, and the people who quietly walk away from it after 18 months don't usually write blog posts about why. So this one will. Storage isn't always the answer — but for a specific, common type of homeowner in Dublin, it is the better trade.
The headline numbers
Rent-a-room: in central Dublin, a furnished single room with bills included goes for €700–€1,000 a month. Under the rent-a-room scheme you can earn up to €14,000 a year tax-free. Net at €1,166/mo: €14,000 a year. Net at €700/mo: €8,400 a year.
Storage: the same spare room, listed on Packhood as a "spare room — locked, indoor, dry, ground floor" lists at €100–€140 a month in central Dublin. €120/mo gross → roughly €72/mo net after the platform fee and tax at 40% marginal → ~€864 a year.
On the headline, rent-a-room wins by 9× to 16×. That's not a close call. So why is anyone choosing storage? Because the headline doesn't include the four hidden costs.
Hidden cost #1 — your kitchen, bathroom, and Wi-Fi are now shared
Sharing a 75m² apartment with one other adult is a different life from living alone in a 75m² apartment. Two people in one shower in the morning. Two cooking schedules in one kitchen. Two heating preferences. Two music tastes at 11pm on a Tuesday.
If you're a single homeowner who travels, has friends over, dates, or just likes silence after a long day at work — you've now agreed to coordinate around someone else for everything. The extra €700–€1,000 a month is real. The cost in lifestyle is also real and harder to put a euro figure on.
Hidden cost #2 — the tenant relationship
Rent-a-room arrangements are governed under licensee status, not tenancy. That sounds clean. In practice, a licensee who hasn't paid for two months, leaves dishes for a week at a time, brings home a different partner every weekend, or has slowly accumulated 14 boxes in the hall — that's a relationship problem you have to solve in person, with someone you live with.
Most landlords do one rent-a-room cycle and either commit fully or quietly pivot to something less personal. Storage is "less personal" in the most useful sense: the renter is never inside your front door past move-in.
Hidden cost #3 — the threshold trap
The rent-a-room scheme has a hard cliff at €14,000. The day you go even €1 over, the entire amount becomes taxable, not just the excess. Many Dublin landlords miscalculate by including bills, included parking, or laundry contributions, then realise at year-end they've blown the limit and the whole €14,200 is now taxable Case I income.
Storage income is taxed normally from euro one. There's no cliff and no surprise. €1,800 of storage income is exactly €1,800 of taxable income. You know on day one what you owe.
Hidden cost #4 — vacancy risk
Spare-room rentals in Dublin have meaningful vacancy: ~3 weeks between tenants is the median, longer if you're picky. During that time you're paying for an empty room (the heat, the rates per-sqft, the opportunity cost) while waiting for the next viewing.
Storage doesn't churn. Median Packhood booking length in IE is 8 months, with ~25% of bookings going past 12 months. A renter storing seasonal kit or business inventory has no incentive to leave; they just keep paying. The long booking is the platform's quietest virtue.
When storage actually wins
Storage is the right answer when one or more of these is true: you live alone and want to keep it that way; you travel for work and don't want to coordinate with a flatmate; you've already done a rent-a-room cycle and the math wasn't worth the friction; the spare room is small (under 7m²) and unglamorous, but dry and lockable; you have a partner who'd veto a stranger living in their house but is fine with strangers' boxes.
It's also the right answer for owners of second properties — an empty parents' house, an inherited terrace in the country, a between-tenants investment property. Spare-room rental requires you to be present (the licensee lives with you). Storage doesn't.
When rent-a-room actually wins
If you genuinely don't mind a flatmate, are prepared to interview, sign agreements, and handle the relationship — rent-a-room's tax efficiency is hard to beat. The €14,000 tax-free is real money, and many homeowners find a good lodger and run the same arrangement for 5+ years happily.
The honest summary: rent-a-room is the right answer if your spare room can comfortably house an adult AND you want one in your home. Storage is the right answer for everyone else with a spare room, especially the ones who tried rent-a-room once and remember why they don't anymore.
How to actually try it
List your spare room as storage on Packhood. The form takes 15 minutes. Five photos: the empty room from the door, from the back wall, the floor, the ceiling/light fitting, the lock. A three-sentence description: where it is (suburb), the dimensions, what's good about it (dry, locked, ground floor, alarmed). Set a price at the city median.
If it doesn't book in 30 days, drop the price 10% and add an extra photo. If it books and the renter is a nightmare, the booking is one calendar month notice and the next one is along the next morning. Low-friction in both directions.
