Supply: fixed by law, shrinking in practice
Balearic law caps tourist places island-by-island; Ibiza's pool is effectively closed. Simultaneously, enforcement against unlicensed holiday rentals has removed thousands of informal beds from the market, and category-upgrade mandates are converting existing hotels upward — reducing key counts as rooms merge into suites. The result is a supply curve that moves only leftward while record demand presses against it: the fundamental behind Ibiza's archipelago-leading ADR growth. International luxury brands have entered through conversion and management contracts rather than development — there is essentially no greenfield path.
Lane economics
Category-upgrade conversion underwrites best: acquisition of dated coastal stock at yields reflecting its current category, capex into repositioning, exit at luxury-boutique multiples — with the state effectively guaranteeing no new competition. Agroturismo offers the only genuine new-key creation, but each rural estate licence is individually negotiated and capped; scale comes from portfolios, not projects. Legal villa operations monetise the ETV licence itself — professionalised management of licensed villas captures rates that rival hotel ADRs at a fraction of the capex. Marina adjacency is rate-leverage: rooms, F&B and beach-club product feeding the island's highest-spend micro-market, where the constraint is reputation and access, not demand.
Structure, partners and the workforce problem
Entry structures concentrate on asset purchase plus brand/management overlay — conversions dominate deal flow. Balearic and island-level government relations are the critical capability: category upgrades, rural licences and marina concessions all run through discretionary approvals. Workforce housing has become a line item no serious operator can omit — hotel groups now lease or build staff accommodation as standard practice, and projects that internalise this cost underwrite; those that ignore it fail operationally in July.
TIO verdict
Ibiza is the clearest scarcity play in European hospitality. The state has capped supply, criminalised the informal competition and committed to upmarket policy — the developer's job is simply to own compliant capacity and raise its rate. Buy licences and legacy stock, convert upmarket, price the workforce honestly, and let each new regulation compound the moat. In a market where building is banned, ownership is the development strategy.
