One of the most overlooked ways to earn extra money is renting out space you already have. A spare bedroom, a finished basement, an empty garage, a driveway, or unused storage can all generate steady income with relatively little ongoing effort. Because you are not buying anything new — just putting an existing asset to work — the return can be excellent. This guide covers the main ways to rent out space, what to consider before you do, and how to handle the money, taxes, and risks responsibly.
Ways to Rent Out Space
- A spare room to a long-term roommate — the steadiest option; a monthly rent that can substantially offset your housing costs
- Short-term rentals — renting a room or unit to travelers can earn more per night but takes far more work and faces local rules
- Parking or driveway space — in busy areas, a parking spot can rent monthly with almost no effort
- Storage space — a garage, basement, or shed rented for someone else’s belongings
- Other space — even a yard, a workshop, or space for events can earn through specialized platforms
A Worked Example
Suppose you rent a spare bedroom to a long-term roommate for $700 a month. That is $8,400 a year — enough to cover a large share of many mortgage payments, and far more than most side hustles earn for the modest effort of sharing your home. Even a humble option adds up: a driveway parking spot at $150 a month is $1,800 a year for essentially no ongoing work. Because the asset already exists and your added costs are small, renting space often delivers a better return on effort than almost any other extra-income idea.
Before You Rent: What to Check
- Local laws and rules — cities, HOAs, and landlords often restrict or require permits for renting space, especially short-term rentals; check before you list
- Your lease or mortgage — if you rent rather than own, your lease may prohibit subletting; mortgages and insurance may have conditions too
- Insurance — a standard homeowners or renters policy may not cover renting out space; talk to your insurer about the right coverage
- Safety and screening — for a roommate, screen carefully and use a written agreement; for short-term guests, follow the platform’s protections
Handle the Money and Taxes Properly
Rental income is generally taxable, so keep clear records of what you earn and the expenses tied to the space (a share of utilities, supplies, repairs, and platform fees may be deductible). Use a written rental agreement even for a roommate, collect a security deposit where appropriate, and keep the rental money organized separately so it is easy to report. If short-term renting becomes substantial, the tax and insurance picture gets more complex — a good moment to consult a professional.
Weigh the Trade-Offs
Renting space means giving up some privacy and taking on a small landlord role — screening, agreements, the occasional repair or awkward conversation. A long-term roommate is the lowest-effort, steadiest option; short-term rentals earn more but demand active management and carry more rules and risk. Match the choice to how much privacy you are willing to trade and how much work you want. For many people, renting a spare room is the single highest-value extra-income move available to them.
Frequently Asked Questions
Is renting out a room worth it?
For many people, yes — it is one of the highest-return extra-income options because the asset already exists and the ongoing effort is low. A spare room can offset a large share of housing costs. The main trade-off is privacy and a small landlord role.
Do I have to pay taxes on rental income?
Generally yes. Rental income is taxable, though related expenses like a share of utilities, repairs, and platform fees may be deductible. Keep good records, and consult a tax professional if your rental activity becomes substantial.
What should I check before renting out space?
Local laws and permit rules, any restrictions in your lease, mortgage, or HOA, and whether your insurance covers renting out space. Screen tenants carefully, use a written agreement, and confirm short-term rentals are allowed where you live before listing.
The Bottom Line
Renting out a spare room, parking spot, or storage space turns something you already own into steady income, often with an excellent return for the effort. Before you list, check local rules, your lease or mortgage, and your insurance, then handle the money with a written agreement and proper tax records. A long-term roommate is the easiest, steadiest path; short-term rentals earn more but demand more. For many, it is the highest-value extra income available.
