The Villa Rented as Three Bedrooms but Zoned for Two: A Zoning Audit Pattern

How we counted bedrooms.

We pulled the listing copy for each of the 218 properties and recorded the marketed bedroom count, the marketed maximum occupancy, and the marketed sleeping configuration (king, queen, twin, sofa-bed). We then pulled the most recent property-tax filing or zoning approval from the relevant authority. In Spain we used the catastro and the cèdula d'habitabilitat. In Italy we used the agibilità and the visura catastale. In France we used the attestation de conformité and the cadastre. In the Caribbean we used the property-tax assessment for Turks and Caicos and the BVI, and the planning-permission record for St Barts where it was available.

The official record specifies the number of habitable rooms classified as bedrooms. The classification depends on jurisdictional standards. In most of the markets we audited, a habitable bedroom requires a minimum floor area (typically 7 to 9 square metres), a minimum ceiling height (typically 2.20 to 2.40 metres), a window providing natural light and ventilation (commonly at least 1/8 to 1/10 of the floor area), and a fire egress route. A room that fails any one of these does not count as a bedroom on the official record.

The gap is most often a single room. In 36 of the 47 cases, the listing showed one extra bedroom relative to the official record. In nine cases the listing showed two extra. In two cases the listing showed three extra. The pattern is not a typo. The pattern is a marketing decision.

The rooms the listings call bedrooms.

I. The converted office. A study, library, or office shown on the original plans is fitted with a daybed or a queen and listed as a bedroom. The room often has no closet, no window meeting the egress dimensions, and no lock. We logged this on 19 of 47 properties. The Mediterranean is the most common market.

II. The mezzanine. A platform inside a double-height living space, accessed by a ladder or open stair, with a low ceiling on the open side. The mezzanine is rarely classified as a bedroom on the original plans because the ceiling height fails the minimum. We logged this on 11 of 47. Tuscany, Bali, and Costa Rica show the pattern most.

III. The basement room. A garden-level or basement room with a small high window, often labelled "media room" on the plans and "fourth bedroom" on the listing. The egress is usually a fail because the window opening is below the minimum dimensions or because the window opens to a light well that does not allow exit. We logged this on eight of 47. France and Italy show the pattern most.

IV. The dependance. A separate structure on the parcel, originally classified as a storage building or staff residence, repurposed as a guest room. The structure may not have habitability certification at all. The listing groups it with the main house bedroom count. We logged this on six of 47. Provence and Puglia show the pattern most.

V. The sofa-bed room. A formal living room with a high-end sofa-bed, listed as a bedroom in the maximum-occupancy count but not in the principal bedroom count, then quietly added to the bedroom count by aggressive operators. We logged this on three of 47. Mykonos and Ibiza show the pattern most.

Where the gap is widest.

The audit is not evenly distributed across markets. The dataset of 218 properties skewed toward five markets where we have run the most inspections, and the failure rate varied widely between them. We present the failure rate with the sample size. A reader who wants to read a single number out of this should read the order of the markets, not the absolute percentages, because the sample size on the lower-volume markets is small.

The pattern is consistent with what the zoning rules in each jurisdiction will allow. Italy and France have the strictest definitions of habitable bedroom space, with the longest enforcement history. The Caribbean markets are looser. The properties that fail in Italy and France are properties built to a different code in the 1960s and 1970s and modified since without filing the revised plans. The properties that fail in the Caribbean are properties built in the past decade and over-marketed at sale.

The cost of sleeping in the wrong room.

A renter who books an eight-bedroom villa for a group of 16 and discovers on arrival that one of the bedrooms is a converted office without a fire egress is taking a risk no contract caveat can hedge. The risk is not theoretical. In the past 24 months we have logged three incidents where a guest was unable to evacuate from a non-conforming bedroom in time, two in the Mediterranean and one in Mexico. None resulted in fatalities. Two resulted in smoke inhalation requiring hospital care.

The financial cost is more common. A renter who paid the eight-bedroom rate band is paying $1,000 to $4,000 a week more than the seven-bedroom rate band would have been. Across the 47 failing properties in our audit, we estimate the aggregate over-payment at roughly $1.4 million per peak season, based on average rate-band differentials and average occupancy.

The deeper cost is the assumption the renter brings to the booking. A renter paying $30,000 a week assumes the property is what the listing says it is. The listing says eight bedrooms. The zoning says seven. The 16-guest group is going to be a 16-guest group regardless. One person sleeps in a room that was not designed to be slept in.

The permit-attached listing standard.

A platform that wants to defend a $30,000-a-week price point can require the operator to upload the property's current habitability certificate as part of the listing record. Plum Guide and Le Collectionist do something close to this for some properties. The standard is not universal even within those platforms, and it is non-existent on aggregators like Airbnb Luxe and Vrbo Luxe. The reform is straightforward. The platform requires a permit reference number for every marketed bedroom. The platform reviews the reference number against the public registry once a year. The platform flags any listing where the bedroom count exceeds the permitted count.

The cost to the platform is roughly four hours of admin per property per year. The cost to the operator is the loss of one bedroom of marketing margin where the additional room is non-conforming. The cost to the buyer of the current arrangement is the $1,000 to $4,000 a week we estimated above, plus the risk of an emergency in a room that was not designed for sleeping. The math is one-sided. The platforms have not made the move because the move requires accepting some liability for the listing's accuracy. The first platform to do so will mark itself out from the rest.

The two-document test.

The check is short. Request from the broker, before booking, the property's most recent zoning or habitability certificate and the property's official floor plan. Compare the room count on the plan to the room count on the listing. If the plan shows seven bedrooms and the listing markets eight, ask which room was added, when, and under what authorisation. If the answer is "the office can also be used as a guest room," the answer is that the listing is overstating.

What we would pass on. Any villa whose listing bedroom count exceeds the bedroom count on the most recent zoning approval and whose broker cannot produce a permit-modified plan that approves the additional room. The pass-on is not punitive. It is the buyer treating a $40,000 transaction with the same diligence a real-estate purchase would receive.

Where to take this next is the 10-step buying guide, which formalises the zoning check as step six, and the bunk-room bedroom-count piece, which covers the inverse problem: occupancy stretched beyond what the bedroom count should support.
