A primary residence can generate income without the need to sell it or take out a new loan. Partial rentals, making unused spaces available, occasional services: the mechanisms vary depending on the available space, local regulations, and the time the owner is willing to dedicate. Here are ten concrete ideas to transform your home into a source of supplementary income.
1. Rent a furnished room while remaining an occupant
Renting a room to a tenant while continuing to live in the property falls under a different regime than traditional seasonal rentals. The annual limit of 90 or 120 days does not apply when the owner remains on-site and the room is part of their occupied primary residence.
This arrangement is suitable for owners with an unoccupied room, particularly after a child has moved out. The signed lease is a standard furnished rental contract, with rent set freely within reasonable limits. One point of caution: check that the co-ownership regulations do not prohibit partial subletting.

2. Seasonal rental of the entire property during your vacations
Renting out your home for short durations during your own absences remains one of the most direct methods to generate supplementary income. The Le Meur law of November 19, 2024, has modified the applicable rules: for income received from 2025, the micro-BIC allowance has been set at 30% with a revenue ceiling of €15,000 for non-classified properties.
The national limit of 120 days per year can now be reduced to 90 days by municipalities. Before publishing an ad on a platform, checking the municipal regulations has become necessary.
The registration of tourist accommodations is gradually becoming widespread at the national level, including for primary residences. A registration number must be obtained from the town hall, which turns this source of income into an activity requiring real administrative follow-up.
3. Install a charging station for electric vehicles
Owners of single-family homes with a garage or parking space can install a charging station and offer it to electric vehicle drivers through dedicated platforms. The installation cost is partially offset by local energy transition aids, and income comes from billing per kilowatt-hour consumed.
This model works particularly well in suburban areas where public charging stations are still rare. Profitability depends on the household’s electricity rate and the number of monthly charges.
4. Rent out your garden or yard for events
A spacious outdoor area can host birthdays, outdoor workshops, or photo shoots. Platforms connecting individuals allow you to offer a garden for half a day or a full day, with a price set by the owner.
The owner’s liability insurance must cover this type of use. A specific insurance contract or an amendment to the multi-risk home insurance is recommended before any rental.
5. Offer a storage space between individuals
Cellars, attics, unused garages: these vacant square meters are of interest to city dwellers lacking space. Peer-to-peer storage is growing on specialized sites that manage the contract and insurance.
Income remains modest per square meter, but the management burden is almost nonexistent. No preparation of the property, no hosting of visitors, no cleaning between rentals. A standard-sized garage can generate regular passive income without any daily interaction with the tenant.
6. Rent a parking space or garage
In large urban areas where parking is scarce, a private parking space rents easily through online platforms or direct ads. The lease is a simple rental contract, distinct from a residential lease, and the notice period for termination is short.
This type of rental does not require any technical diagnostics or declaration of tourist accommodation. Charges are limited to basic maintenance and, if applicable, to co-ownership fees related to the lot.
7. Transform a space into a shared office by the day
Remote work has created a demand for quiet workspaces, rented by the day or half-day. An independent room with a desk, reliable internet connection, and separate access can be made available on peer-to-peer coworking platforms.
This model is suitable for properties located in city centers or near train stations. The advantage over seasonal rentals: no linen to provide, no kitchen to equip, and limited time slots that preserve the household’s privacy.
8. Host a photo or video shoot
Production agencies regularly seek authentic settings for advertising shoots, music videos, or photo sessions. Properties with distinctive architectural features (moldings, old parquet, unobstructed views) are particularly in demand.
Compensation for a day of shooting far exceeds that of a night in seasonal rental. Specialized platforms connect owners and image professionals, with a commission taken from each booking.
9. Host a relay antenna or advertising panel
Owners of houses located at height or along busy roads may be approached by telecom operators or advertising agencies. Installing a relay antenna on a roof or an advertising panel on the facade entitles the owner to an annual rent set by contract.
The constraints are regulatory: planning permission, compliance with the local advertising plan, and agreement from the co-ownership if applicable. The income is stable and indexed, but the initial negotiation requires particular attention to duration and renewal clauses.
10. Grow and sell produce from your vegetable garden
A large plot allows for the production of fruits, vegetables, or herbs sold through short circuits. Direct sales to neighbors, at a local market, or via a CSA do not require a commercial status as long as the activity remains occasional and the amounts are modest.
- Seasonal vegetables grown without chemical treatment find eager buyers among local consumers sensitive to short circuits.
- Dried herbs (thyme, rosemary, mint) have a long shelf life and sell at a price per kilo significantly higher than fresh vegetables.
- Surplus production can also be turned into preserves or jams, provided local health standards are respected.
Every primary residence holds at least one space, time slot, or underutilized equipment. The choice of formula depends on the available time, tolerance for third-party access to the property, and municipal regulations. Always check the reporting and insurance obligations before receiving the first euro, as this precaution conditions all others.
