In brief
In 2026, Parisian storage rooms offer the highest gross yield in the Paris property market, 6 to 10%: a 5 to 10 sqm storage room is bought for 10,000 to 30,000 euros (1,500 to 4,000 euros/sqm) and rents for 60 to 120 euros/month. A combined parking-and-storage lot at 28,000 euros (a 12 sqm garage rented at 180 euros/month, an 8 sqm storage room at 70 euros/month) generates net income of 2,420 euros/year, a 7.76% net yield, with no rent control, no winter eviction ban, no energy rating and no decency decree. These lots are mostly found through condominium managers, notaries and auction sales, rarely on standard portals, and ideally complement a residential portfolio through their immediate cash flow. Home Select, a property hunter in Paris since 2011 (16 buying agents, 1,200+ buyers supported), spots ancillary lots available in the condominiums where it identifies apartments, for a fee of 2.5% of the purchase price (minimum 10,000 euros incl. VAT) and 6% average negotiation off the seller's price.
Key takeaways
- Parisian storage rooms offer gross yields of 6 to 10%, the highest in the Paris property market, with prices from 10,000 to 30,000 euros
- A combined parking and storage lot at 28,000 euros collects 250 euros per month in rent, over 200 euros of it as net cash flow, for a 7.76% net yield
- Micro-investments in ancillary lots face no rent controls, no winter eviction ban and no energy rating requirements
- Condominium managers, notaries and auction sales are the main sources for finding underpriced ancillary lots
A lock-up garage at 22,000 euros returning 6.8% net. A storage room at 12,000 euros returning 9% gross. A combined parking and storage lot at 28,000 euros collecting 250 euros/month in rent, more than 200 euros of it as immediate net cash flow. Parisian property micro-investments are the market’s worst-kept secret, probably because they do not inspire dreams. In terms of pure yield, no Parisian apartment can compete.
What yield does a storage room in Paris produce?
A 5 to 10 m² storage room sells for 10,000 to 30,000 euros in Paris (1,500 to 4,000 euros/sqm) and rents for 60 to 120 euros a month, a gross yield of 6 to 10%: the highest in the Paris property market. On one precise case, a 6 m² storage room in the 11th bought for 12,000 to 15,000 euros and rented at 80 to 100 euros a month comes out between 7 and 10%, at the top of the range.
Parisian storage rooms thus represent the highest gross yield in French property, a level that even the best parking spaces cannot match.
Demand comes from three sources. Personal storage (Parisians lack space in increasingly small apartments). Professional storage (self-employed workers, e-commerce sellers who need accessible space at low cost). Wine cellars (a clientele willing to pay a premium for a temperature-controlled, secure space, with rents of 100 to 150 euros/month for well-maintained 8 to 10 m² rooms).
Prices vary by arrondissement. In the 18th, 19th and 20th: 1,500 to 2,000 euros/sqm, i.e. 7,500 to 16,000 euros for 5-8 m². In the Marais or the 6th: 3,000 to 4,000 euros/sqm, offset by rents of 80-100 euros/month. The most sought-after rooms, those in good condition, dry, easily accessible, in secure basements, sell above these averages and rent within days.
Why add ancillary lots to a residential portfolio?
Because three to five ancillary lots bought for 80,000 to 120,000 euros generate 500 to 800 euros of monthly cash flow, or 6,000 to 9,600 euros a year: the equivalent of an extra studio for an investment three to four times smaller. They also bring complete regulatory diversification, since rent controls, the winter eviction ban and energy ratings do not apply to them.
The dedicated article on parking spaces in Paris covers investing in a standalone garage. Here, we address building a portfolio of ancillary lots as a complement to a residential property portfolio.
An investor holding two rental studios (approximately 400,000 euros in capital) can diversify by adding three to five ancillary lots for 80,000 to 120,000 euros. These lots generate monthly cash flow of 500 to 800 euros, or 6,000 to 9,600 euros/year: a supplementary income equivalent to that of an additional studio, for an investment three to four times smaller.
Risk diversification is the first advantage. A parking space and a storage room do not depend on the same tenants, the same regulations or the same cycles as apartments. No rent controls, no winter eviction ban, no energy rating, no minimum decency standards. If a parking tenant leaves, the monthly loss is 150 euros, not 1,200 euros.
Immediate cash flow is the second advantage. An ancillary lot is often purchased outright (no credit needed for 20,000 euros) and generates income from the first month. For an investor who has finished repaying their mortgages and is looking for liquid yield, it is an ideal vehicle.
What does a combined parking and storage lot in the 11th actually earn?
On a lot sold at 28,000 euros, or 31,200 euros including notary fees, and rented for 250 euros a month in total, gross annual income is 3,000 euros: 9.62% gross and 7.76% net after 580 euros of charges. After tax under the micro-foncier regime, 1,429 euros a year remain, a 4.58% net-net yield.
A lot comprising a 12 m² lock-up garage and an 8 m² storage room in an 11th arrondissement condominium, sold as a single lot at 28,000 euros. Notary fees (high fixed notary charges on small amounts): 3,200 euros. Total investment: 31,200 euros.
The garage rents at 180 euros/month. The storage room rents at 70 euros/month for storage. Gross annual income: 3,000 euros. Gross yield: 9.62%.
Charges are minimal. Condominium: 400 euros/year. Property tax: 120 euros. Insurance: 60 euros. Total: 580 euros. Net income: 2,420 euros. Net yield: 7.76%.
Under the micro-foncier regime (30% flat-rate deduction, applicable if total rental income is below 15,000 euros), taxable income of 2,100 euros. At a 30% marginal rate plus 17.2% social levies, tax of 991 euros. Net-net yield: 1,429 euros, or 4.58%. That is double the net-net yield of a studio in the same arrondissement.

What are the constraints of a Paris storage room?
Three constraints drive the yield: dampness, accessibility and security. Dampness is the number one risk; accessibility and security shift the rent by 20 to 30% for the same surface area.
Dampness is the number one risk. 19th-century Parisian basements are rarely waterproof. Infiltration from the water table or perimeter walls damages stored goods and discourages tenants. Inspect during rainy periods and check general assembly minutes for past claims.
Accessibility determines the rent. A first-level basement with a wide, well-lit staircase commands 20-30% higher rent than a third-level basement behind two fire doors. Professional tenants (e-commerce storage) need regular access with boxes: difficult access eliminates them.
Security is the third factor. Basement break-ins are common. A secured basement (reinforced doors, lighting, CCTV) justifies 20 to 30% higher rent.
Where do you find parking spaces and storage rooms to buy in Paris?
Not on standard property portals, which list only a minority of them: the four good channels are condominium managers, notaries, auction sales and condominium general meetings. Managers sell off abandoned lots at 50-70% of market price, which makes them the most profitable source.
Ancillary lots are not found on standard property portals. Condominium managers sell off abandoned lots (unpaid charges) at 50-70% of market price. Notaries sell inheritance lots at a discount. Auction sales offer attractive starting prices with limited competition. General assembly meetings sometimes vote on the sale of communal lots that have been repurposed: an attentive co-owner can seize these opportunities as a priority.
How is income from a parking space or storage room taxed?
As property income (revenus fonciers) as soon as the lot is rented unfurnished, under the micro-foncier regime and its 30% flat-rate deduction as long as total property income stays below 15,000 euros. Above that threshold, the actual expenses regime applies.
Parking and storage income counts as property income (revenus fonciers) when rented unfurnished. The micro-foncier regime (30% flat-rate deduction) applies if total property income does not exceed 15,000 euros. Beyond that, the actual expenses regime applies with deduction of charges and loan interest.
For storage rooms rented as fitted professional storage space (shelving, lighting, secure access), furnished rental status may be claimed, opening access to LMNP depreciation. This optimisation should be discussed with an accountant.
Do ancillary lots really build wealth?
No: they generate cash flow, not capital gains. A parking space bought for 22,000 euros in 2026 will be worth 25,000 to 28,000 euros in ten years, whereas an apartment works through capital appreciation and mortgage leverage.
In a diversified wealth strategy, ancillary lots play the role of cash-flow generators. They do not build wealth in the sense of capital appreciation: a parking space bought for 22,000 euros in 2026 will be worth 25,000-28,000 euros in ten years. But they produce regular, predictable income with minimal management.
The ideal combination: one or two apartments (wealth building through capital gains and leverage) and three to five ancillary lots (cash-flow generation and improved overall yield). This diversification protects against risks specific to each asset type and smooths the total return.
Our property hunters do not handle standalone parking purchases (disproportionate fees), but we direct our clients towards the right channels and check the ancillary lots available in condominiums where we identify apartments. A service that costs nothing and can generate thousands of euros in annual yield.

Frequently asked questions
01 What yield can you expect from a rented storage room in Paris?
Parisian storage rooms offer a gross yield of 6 to 10%, the highest in the Paris property market. A 5 to 10 m² storage room purchased for between 10,000 and 30,000 euros (1,500 to 4,000 euros/sqm) rents for 60 to 120 euros/month.
02 How do you find parking spaces and storage rooms to buy in Paris?
Condominium managers (abandoned lots), notaries (inheritances), auction sales, and general assembly meetings (sale of communal lots). Standard property portals list only a minority.
03 What are the risks of investing in a storage room in Paris?
Dampness (frequent water infiltration), limited accessibility, security (break-ins in unsecured basements) and low capital appreciation potential. The rental yield compensates, but capital growth is virtually nil.
04 Can you buy a combined parking space and storage room lot?
Yes, combined lots are common in older condominiums. The combined price is often lower than the sum of separate lots, and the overall yield is optimised through pooled charges.
