Can your sister and her family use the house in October when you are not there? Of all the questions buyers ask before purchasing a share in a luxury holiday home, this one comes up earliest and most often — usually before anyone has asked about title deeds, management fees or resale. It is a revealing question, because it goes to the heart of what co-ownership actually is. You are not booking a hotel, where the answer would be no. You are not buying a timeshare, where the answer would be buried in a clause. You own a deeded share of a real house, and the people you love are part of the reason you bought it.
The short answer, at almost every professionally managed co-ownership property, is yes — and the long answer is the subject of this guide. Every shared home operates under a set of usage rules written into the ownership documents: who may stay, whether days can be lent or rented, what happens when a glass door meets a football, whether the dog comes too, and who decides if the kitchen gets remodelled. These rules are not bureaucratic decoration. They are the reason eight families can share one house for a decade without a single argument about it, and understanding them before you buy is one of the simplest pieces of due diligence available. What follows is how the rulebook typically works across the homes listed on Co-Ownership Property, and where the answers genuinely differ from one property to the next.
Guests: Your Time Is Yours to Share
Start with the easiest rule, because it is the one that matters most to families. When you stay in your co-ownership home, you may bring whoever you like — children, parents, friends, the university roommate who always promised to visit. Your allocated days are your private occupancy of the entire house, up to the property''s stated sleeping capacity, and nobody registers an opinion about your guest list any more than a neighbour would. A couple who own a share in a four-bedroom villa in Valbonne can fill all four bedrooms every time they visit. For most owners this is the entire point: the second home exists precisely so that the long table on the terrace has people around it.
The more interesting question is the unaccompanied guest — the sister in October. Here the prevailing model across the luxury co-ownership sector is generous but deliberate: owners can generally lend a stay to family or friends without being present themselves, provided the stay is booked under the owner''s allocation and the guests are registered with the management company in advance. The registration step is not box-ticking. The house team needs to know who is arriving so the property can be prepared, keys or access codes issued, and someone reachable if a shutter jams. The guest occupies the home under the owner''s responsibility — financially and behaviourally — which is exactly the discipline that keeps the arrangement working. Lending a week to your closest friends is hospitality; the agreement simply makes sure it never quietly becomes something else. The detailed mechanics — booking windows, capacity limits, registration — are covered in our staying FAQs.
The Rental Question: Why Most Luxury Co-Ownerships Say No
That "something else" is the rental question, and it is where the philosophy of a co-ownership scheme shows itself most clearly. Across the premium end of the market, the dominant position is that shared homes are for owners and their personal guests, not for paying strangers. The reasoning is practical rather than precious. A house that receives a rotating cast of holiday renters wears differently from a house used by eight known families. Renters have no stake in the furniture surviving the summer; owners do. Neighbours, too, respond very differently to a home occupied by its owners than to one operating as an unofficial hotel — and in an era when many European municipalities are restricting short-let licences, a personal-use covenant keeps the property entirely clear of that regulatory front line.
That said, the market is not uniform, and this is one of the questions worth asking about any specific listing. A minority of schemes — more common in the United States than in Europe — permit owners to release unused days into a managed rental pool, with income offsetting running costs. Where rental is possible at all, it runs through the management company under the property''s licensing, never as a private side arrangement. The honest summary for a buyer is this: if your plan depends on rental income, say so at the first conversation, because it will narrow your shortlist considerably — and if your plan is purely personal use, the no-rental covenant at most properties is not a restriction but a protection. It is one of the structural differences between genuine co-ownership and a timeshare, a distinction we unpack in Fractional Ownership vs Timeshare.
Pets: The Most Personal Rule in the Book
No usage rule generates more correspondence than the dog. This should surprise nobody: according to the European pet food federation FEDIAF, 49 per cent of European households — some 139 million homes — keep at least one pet, and for many families the spaniel is as non-negotiable a travel companion as the children. Co-ownership schemes know this, and pet policies are set home by home rather than platform-wide. Some properties are explicitly pet-friendly, with the deep-clean between stays priced into the operating budget. Others — typically apartments in historic buildings, or homes where a co-owner group has agreed an allergy-conscious standard — are pet-free, full stop.
The important point is that the policy belongs to the property, not to you, and it is fixed before you buy rather than negotiated afterwards. A pet-free house stays pet-free because eight owners bought it on that understanding; a pet-friendly house budgets honestly for the extra housekeeping. Neither model is superior — but a buyer with a labrador should treat the pet policy as a primary search filter, alongside location and share price, rather than a detail to resolve later. It is precisely the kind of question our team answers before a viewing is ever arranged; ask it early.
Damage, Wear and the Difference Between the Two
Things break. In a house that hosts eight families across roughly fifty weeks of occupancy a year, things break more often than in a house that sits empty for ten months — which is, perversely, a sign of health. The rulebook''s job is to distinguish between two categories that look similar and are treated completely differently. Fair wear and tear — the sofa that softens, the dishwasher that retires after a decade, the repainting cycle — belongs to all owners collectively and is funded through the annual budget and reserve fund, exactly as described in our guide to the annual management fee. Damage during a stay — the wine on the rug, the cracked glass door — belongs to the owner whose stay it was, whether the foot that did it was theirs, their teenager''s or their lent-out guest''s.
In practice the system is undramatic. The management company inspects the property between every stay, so the house is documented dozens of times a year and questions of attribution rarely survive contact with the photographs. Minor damage is repaired immediately from house funds and recharged to the responsible owner; significant damage runs through the property''s insurance, with the policy held by the ownership entity itself. What the between-stay inspection really buys, though, is something subtler than accountability: every owner arrives at a house in verified, hotel-standard condition, every time, with no inherited mess and no suspicion. Couples who have previously shared an informally co-owned family house with siblings tend to recognise instantly what that is worth.
Can You Change the House?
The final cluster of rules governs the house itself. You own a share of the property, so may you repaint the kitchen the green you have always wanted? Alone, no — and a moment''s reflection explains why. The interior of a shared home is a common asset, curated to a standard all eight owners bought into. What you may do is propose. Improvements, replacements and upgrades are decided collectively through the ownership entity''s governance — typically a vote weighted by share, with the management company implementing whatever the owners approve and the cost flowing through the agreed budget. The mechanics of how eight owners actually reach those decisions, from pool heating upgrades to full refurbishments, are the subject of our guide to LLC governance and voting.
What remains personal is storage. Most professionally managed shared homes provide each owner with a private, lockable owner''s closet — space for the wetsuits, the espresso machine you trust, the children''s beach kit, the case of local wine that did not fit in the car. Between stays the housekeeping team resets the house to its shared standard and your personal world waits in the cupboard. It is a small detail that does a great deal of psychological work: the house always feels cared-for and consistent, yet within twenty minutes of arrival it also feels unmistakably yours.
Why the Rules Are the Point
It is tempting to read a usage agreement as a list of restrictions, and buyers occasionally do, comparing it unfavourably with the imagined freedom of owning a whole house alone. The comparison misses what the rules purchase. The wholly owned second home has no rulebook — and also, very often, no between-stay inspections, no reserve fund, no governance for disagreements between the family members who informally share it, and no answer when the question of the sister in October curdles into the question of whose children scratched the dining table in August. The co-ownership rulebook is two decades of other people''s holiday-home disputes, distilled and solved in advance. Within its lines, the experience is strikingly free: your weeks, your guests, your dog where the house allows, your voice in how the home evolves — at one-eighth of the capital and one-eighth of the running costs, or one-twelfth at city residences such as the Saint-Germain-des-Prés apartment, where roughly four weeks a year of Left Bank life comes with the same quiet machinery behind it.
Owners tend to stop noticing the rules within a year, the way one stops noticing the banister on a well-built staircase. What they notice instead is the life the rules make possible: the October week lent to the sister, the friends'' faces at the long table, the house that is always ready. That is the second life a share buys — not a contract, but the seasons it quietly organises. To see how the structure works end to end, start with how it works, browse the current homes, or speak with our team about the usage rules at any specific property — including the one your sister has already mentally moved into.
