Key takeaways
- Over a recurring schedule of two to three weekly nights (covering three to four days on site) lasting several months, the cost difference between housing options amounts to thousands of euros per employee per year: approximately €5,712 under a defined-days lease compared to €9,360 for tourist rentals and €13,200 for hotel stays.
- A defined-days lease bills only for the nights actually occupied rather than continuous full-time presence: a single, predictable budget line replaces a constant stream of individual expense reports.
- Each employee signs an independent civil defined-days lease, with zero financial joint liability toward potential co-occupants of the property: the employer is never exposed to third-party defaults or behavior.
- The average cost for two nights per week (covering 3 days on site, e.g., Tuesday evening to Thursday morning) under a defined-days lease (at €55 per night) totals approximately €476 per month (based on an average of 4.33 weeks per month). For a single night per week (2 days on site), the budget drops to approximately €238 per month.
A consultant travels two to three days per week to a client site across the country. A new hire begins a probation period far from their primary residence. A hybrid team returns to the office on a fixed part-time schedule. In all three scenarios, the same question lands on the HR Director’s or Office Manager’s desk: how much will housing cost for this employee on assignment, and which budget line should cover it?
The cost of employee housing on a recurring assignment cannot be calculated by simply multiplying single hotel night rates. Over a recurring schedule extending across several months, the financial gap between accommodation formats reaches thousands of euros per employee annually. This article compares, backed by real data, the three options companies evaluate for a recurring assignment (requiring two to three nights per week, covering three to four days on site): hotels, short-term tourist rentals (often managed as aparthotels), and the defined-days lease, the contract framework governing part-time furnished rentals at Kowo. The objective: establishing a clear monthly and annual budget for your next HR framework decision.
Why a recurring assignment is not a standard business trip
Standard corporate travel budgeting relies on the assumption of isolated overnight stays: an employee travels, stays one or two nights, returns, and accounting processes a single expense report. This model works seamlessly for occasional round trips. However, it quickly becomes inefficient when the schedule repeats weekly (two or three recurring nights over several months): the employee is no longer making occasional trips, but managing a professional dual residence between their primary family household and the assignment city.
From a legal perspective, this secondary weekday home occupied a few fixed days a week constitutes a secondary residence for the employee. Setting up this accommodation falls under the French Civil Code (Articles 1714 and following), rather than restrictive primary residence rental laws. This flexible framework allows companies to establish custom contracts tailored to the employee’s actual work rhythm, rather than paying full-time rent for partial usage.
What directly impacts corporate housing budgets
Four core parameters dictate the real cost difference between market options:
- Contractual fixed nights: a defined-days lease locks in occupied days and nights from day one (for instance, Tuesday evening to Thursday morning, which equals 2 nights / 3 days on site) with pro-rated monthly rent, whereas hotels or short-term rentals bill each night at fluctuating market rates.
- Cost per occupied night, not paid night: traditional full-time monthly leases charge for seven nights a week even if the employee stays only two or three nights; a defined-days lease charges strictly for scheduled nights.
- Single budget line: a written lease agreement replaces an endless stream of individual hotel expense receipts, securing a guaranteed rate for the assignment duration.
- Fixed address and personal comfort: unlike short-term tourist rentals where addresses change based on availability, a defined-days lease guarantees the same apartment week after week. The employee benefits from a locked storage locker to leave personal belongings on-site.
Employee housing cost on assignment: a financial breakdown
Consider a common corporate scenario: an employee present 3 days per week requiring 2 fixed weekly nights (e.g., Tuesday evening to Thursday morning). Below are the monthly and annual accommodation costs across available options (based on an average of 4.33 weeks per month and €55 / night under a defined-days lease):
- Kowo defined-days lease (2 nights / 3 days per week): €55 per night on average, amounting to €476 per month and €5,712 per year. (For 1 single night per week / 2 days on site, the budget is approximately €238 per month).
- Tourist rental / aparthotel: approximately €780 per month for the same 2-night frequency, totaling €9,360 per year.
- Standard hotel: approximately €1,100 per month (based on an average rate of €125 per night for 2 nights), totaling €13,200 per year.
- Traditional full-time monthly rental: a studio rented full-time costs €1,200 to €1,500 per month for the same occupied nights, totaling €14,400 to €18,000 per year.
Annual savings per employee are substantial: choosing a defined-days lease for 2 nights per week saves approximately €3,648 per year compared to tourist rentals, and €7,488 per year compared to hotels for identical usage. If the assignment requires 3 fixed nights per week (covering 4 days on site, at €55 per night), the defined-days lease budget becomes approximately €714 per month (€8,568 per year), maintaining massive cost savings over hotel rates.
Impact on employee performance and talent retention
Beyond financial savings, housing quality on business assignments directly affects employee retention and Quality of Working Life (QVT). Repeated hotel stays create latent fatigue, leading to burnout and assignment friction.
Providing a fixed weekday home with a locked storage locker allows employees to leave personal belongings, workout clothes, and toiletries on-site. The employee travels light on Mondays with just a laptop bag, arriving in a welcoming, home-like environment. This stability increases productivity and signals strong employer support.
Why property hosts welcome corporate employees
When budgeting corporate housing, companies often ask: will property hosts accept this part-time arrangement? For hosts owning furnished apartments or secondary residences, a corporate employee on a recurring assignment is an ideal profile:
- Payment is reliable and regular.
- Presence days and nights are known in advance and remain stable throughout the year.
- The property is respected by a responsible professional on business travel.
Unlike the constraints of mobility leases or short-term tourist lodging (revolving turnover, property damage, heavy management), part-time rentals provide hosts an ideal balance between yield and peace of mind. Furthermore, each employee signs their own independent defined-days lease, with zero joint liability toward potential co-occupants of the same apartment.
Accounting and tax treatment of assignment housing expenses
Managing corporate overnight accommodation costs requires strict compliance with tax and social security regulations (Urssaf). For recurring assignments, financial departments utilize two primary reimbursement methods:
1. Rent reimbursement backed by receipts
The company can reimburse the employee the rent specified in the defined-days lease (€476 per month for 2 nights/week). Monthly rent receipts issued by the host serve as official accounting proof. How the Urssaf treats this coverage is explained in housing an employee in France: how it works.
2. Allowance for long-distance travel expenses
According to the Urssaf, the employer can also pay flat-rate long-distance travel allowances, one for accommodation and one for meals, within exemption limits that decrease as the assignment lengthens. The conditions and the 2026 scale are covered in our guide to the long-distance travel allowance.
Do not confuse: mobility leases, tourist rentals, and business travel expenses
Be careful not to confuse defined-days leases with neighboring accommodation mechanisms:
- Mobility lease (bail mobilité): capped at 10 months and restricted to specific legal reasons, it rents properties on a full-time continuous basis. For an employee present 2 nights per week, the company pays rent for empty nights.
- Short-term tourist rentals: designed for occasional tourism, lacking guaranteed rates or address stability across months.
- Isolated travel expenses: designed for one-off overnight stays, not for recurring work schedules established across semesters or years.
Checklist before finalizing your corporate HR budget
- Exact number of required nights per week (e.g., 2 nights from Tuesday evening to Thursday morning, covering 3 days on site).
- Estimated assignment duration to match contractual commitment windows.
- Accounting reimbursement format: rent reimbursement backed by receipts or flat-rate long-distance travel allowance.
- Contractual notice period clauses allowing lease termination without penalty if an assignment ends early.
Frequently asked questions

No: on Kowo, the lease runs for at least three months. For very short-term needs, hotels or aparthotels remain simpler.
Who signs the lease agreement?
On Kowo, the lease is signed by the employee in their own name; the company can cover the rent under its reimbursement policy.
How do you substantiate this expense?
Rent receipts, issued every month through Stripe, can be used for expense reports.
