Buying apartments and condominiums in Monaco: a buyer’s decision guide

Start with the use, not the view

Choose the apartment that can legally and practically serve your intended use, rather than the listing with the most attractive photographs. Before requesting an address, define whether the home is for full-time occupation, occasional stays or letting; required bedrooms and usable floor area; step-free access; parking and storage; privacy; noise tolerance; and a maximum all-in budget. Ask the agent for a dated floor plan, the unit and accessory lot numbers, the stated area-measurement basis, annual building charges, occupancy status and the applicable co-ownership rules. No advertised unit is assumed to be available. Reject a candidate early if an essential requirement cannot be supported by documents, even if the location is prestigious.

Compare building types before comparing asking prices

A recently completed serviced residence may offer concierge services, modern equipment and better accessibility, but the service package, staffing and shared plant can generate significant recurring charges. A conventional older apartment may have a lower stated service bill yet require lift, facade, plumbing or energy-system works. A smaller historic building can provide character but constrained access and a higher likelihood of specialised maintenance. A converted or mixed-use building may create commercial noise and use restrictions. None of these descriptions establishes the condition of an individual property. Compare at least two genuinely suitable alternatives on identical criteria: net usable space, light and orientation, privacy, actual amenities, service-charge inclusions, projected works, and documented rights.

Read Monaco price data as context, not a quotation

Monaco's 2025 property-market statistics, discussed after the February 2026 IMSEE release, put an estimated average price at about €57,569 per square metre. This is a market-wide modelled estimate, not an offer price or valuation of a particular condominium. IMSEE changed its methodology for 2025 to incorporate both sales and resales and building age; comparisons with figures issued under the earlier method are therefore not like-for-like. Unit size, floor, exposure, condition, legal rights, outdoor space and quality of the building can cause material deviations. Request recent, genuinely comparable completed transactions and a written explanation of the area measure and adjustments; do not multiply a headline city average by marketing floor area and treat the product as the apartment's value.

The same IMSEE model estimated €71,167/m² for Larvotto and €43,797/m² for Les Moneghetti in 2025; it reported no Monaco-Ville estimate because transaction evidence was insufficient. These are district-level estimates, not transaction quotes or prices for an available apartment. If two candidates are in different districts, compare like-for-like completed sales, building condition and legal rights before attributing their price gap to location alone.

Confirm the precise lot and the chain of title

Monaco's Law No. 1.329 of 8 January 2007 governs buildings divided into co-ownership lots consisting of a privately owned part and a share of common parts. Ask the Monaco notary to check the current title, prior transfers, recorded encumbrances and mortgages, cadastral or lot plans, the co-ownership regulations (règlement de copropriété) and the sale description. The 1862 ordinance on transcription provides for real-property conveyances to be recorded at the Conservation des hypothèques; the recording process and third-party effectiveness matter. Neither a sales brochure nor an agent's statement establishes ownership of a cellar, parking space, secondary entrance or other accessory. Match the exact legal lot references against the physical tour and the draft deed before committing funds.

Differentiate ownership from exclusive enjoyment

A landscaped courtyard, terrace, roof area, garden or parking facility visible from a unit may not form part of the buyer's private property. Monaco's 2022 amendments to Law No. 1.329 distinguish special common parts belonging jointly to some co-owners from common parts allocated for exclusive enjoyment by one lot; the latter remain common property and the exclusive-use right is attached to the lot. Their existence must be expressly identified in the co-ownership regulations. Ask who may enter, who insures and maintains the area, which charges follow the right, whether works need approval and whether any informal exclusive arrangement is documented. Do not price shared space as freehold private floor area.

Underwrite the building, not just the apartment

Request at least the latest available approved budgets and financial accounts, recent general-meeting minutes, the current service-charge allocation for this lot, arrears attributable to it, insurance evidence, and schedules of authorised or proposed major works. Separate routine management, security and concierge, energy, lift and plant servicing, special charges and exceptional levies. Under the co-ownership framework, common-part upkeep and collective-service costs can be allocated on different bases, and special common parts may produce special charges. Ask the syndic or competent representative for documentary confirmation, with the seller's cooperation where necessary. A low historic annual charge is not proof that a facade, lift or waterproofing project is funded; build a reserve for unexpected works.

Use the law actually in force on the transaction date

Law No. 1.590 of 19 May 2026 was published on 29 May 2026 but expressly takes effect on 1 July 2027. It revises the syndic's record-keeping and financial-management obligations, including individualised bank-account arrangements for co-owner associations and defined access to records, with transitional rules for existing appointments. These future requirements must not be presented as obligations already operative in October 2026. For a 2026 purchase, inspect the law and valid documents as they stand today, plus the building's preparation for the 2027 changes. Obtain a date-specific Monaco-law opinion if management quality, a disputed charge or a change of syndic could influence the purchase.

Investigate protected-sector and existing tenant rights

Do not assume every apartment can be let at a freely negotiated rent or delivered vacant on completion. Law No. 1.235 of 28 December 2000 regulates the letting of certain residential premises built or completed before 1 September 1947, subject to statutory exceptions and subsequent amendments. Where applicable, the regime includes protected tenant categories, priority rules and regulated procedures; age alone does not conclusively establish the property's status. Ask for written confirmation of the unit's regime, existing leases, occupants, notice history, vacancy documentation and any State rights relevant to the proposed transaction. If immediate personal occupation or investment letting is essential, have the notary and independent Monaco counsel test that exact scenario before signing a binding agreement.

There is a separate sale-stage risk under Article 38 of Law No. 1.235 where that provision applies. The owner or acting notary must submit a notice of intended disposal to the Minister of State; the notice constitutes an irrevocable offer for one month, during which the State may elect to buy on the stated terms. If it does not, notification to an existing tenant and any applicable tenant rights must still be examined. Building age or a claim of vacant possession cannot replace an analysis of exemptions. Where the dwelling is let and the statutory tenant pre-emption step applies, the notice to the tenant constitutes a separate irrevocable offer for 15 days from receipt. Acceptance may be subject to a statutory financing condition; verify the outcome of that stage before completion. Require the notary to identify whether Article 38 applies, document each required notice and clearance, and reflect the timing and consequences in the preliminary contract.

Separate ownership, planning permission and residence

Owning a Monaco apartment does not by itself confer residence status, tax residence, a right to operate holiday accommodation or permission for structural alterations. Confirm intended occupation, permitted professional or short-stay use, building destination, leases and any authorisations with the competent Monaco professionals and authorities. For refurbishment, check whether changes affect load-bearing structure, facade, common installations, floor area or regulated heritage; secure the required owners' and public approvals before works. Financing and personal immigration or fiscal eligibility must be assessed separately from the conveyance. A property that cannot serve the buyer's intended use is unsuitable even if the title is otherwise sound.

Commission inspections that address the actual building

An independent inspection should examine moisture and waterproofing, windows, ventilation, plumbing, electrics, air-conditioning, acoustics, lift access and the condition of shared plant, with specialists where justified. Inspect at different times if road traffic, construction or neighbouring commercial activity could affect use. Compare the as-built layout with the contractual plans, identify undocumented alterations, ask about permits and warranties, and establish who bears the cost of making any defects good. An attractive renovation inside one apartment does not cure a deteriorating facade or unsettled shared-water ingress claim. Record defects with photographs, estimates and an agreed remedy or price adjustment; do not rely on verbal assurances.

Model the cash requirement and the holding cost separately

Prepare a written purchase-cost statement from a Monaco notary for the particular asset and purchaser structure: price, applicable registration or transfer duties, notarial charges, intermediary fee and its payer, financing security costs, due-diligence fees, and any tax or entity-structure consequences. Do not apply a universal fee percentage without checking current law and the deed. Separately model annual service charges, utilities, insurance, maintenance, any mortgage payments and a capital-works buffer. For money held in a non-euro currency, the effective EUR funding cost depends on the bank's actual exchange rate, spread, transfer charges and transfer date; a reference exchange rate is not a bank's execution rate. Do not confuse gross rental yield with net return after vacancy, legal restrictions and costs.

For a qualifying resale, Monaco Law No. 580 (as amended) sets a 4.75% registration rate for an individual or a qualifying Monaco civil company with identified individual owners; the general rate for other entity acquisitions is 7.5%, while the specified non-transparent beneficial-ownership cases attract 10%. These are conditional legal categories, not interchangeable buyer estimates. The notarial remuneration follows the regulated Monaco notary tariff (Sovereign Ordinance No. 15.252), which is degressive, plus disbursements; ask the notary for the exact amount for the sale price. As an illustration only, a €2 million qualifying individual resale suggests €95,000 registration duty, before notarial remuneration, agency commission, financing, other charges and any case-specific differences. A VAT-covered new-build transaction requires a different calculation. Have the notary confirm the applicable regime, transaction value and detailed total before agreeing to buy.

Stage the purchase and preserve exit conditions

Before a reservation, deposit or preliminary promise, select an independent Monaco notary and, where needed, local counsel and a technical surveyor. Request seller identity and authority, title evidence, mortgage and charge searches, co-ownership papers, the apartment's occupancy and rental status, permits, planned works, and a source-of-funds checklist. Agree in writing what is included in the price and who pays each cost. Have advisers specify finance, vacant-possession, document-verification and defect conditions; remedies and refund mechanics must be explicit, not presumed. The notary should verify deed formalities, settlement instructions and registration/transcription requirements. Do not transfer a deposit to unverified banking coordinates or assume a signature alone resolves financing, possession or third-party rights.

Use a documented proceed, renegotiate or stop test

Proceed to detailed contract drafting only when the lot boundaries and accessory rights match the intended use, the seller can convey the agreed interest, occupation and letting constraints are understood, physical defects are costed, and the full first-year and forward building liabilities are affordable. Renegotiate or condition the price if a documented repair, charge assessment or solvable title discrepancy changes the economics. Stop if ownership or rights cannot be evidenced, vacant possession is indispensable but unachievable, required authorisations are unavailable, major expenditure is unquantifiable or funds cannot be protected under acceptable conditions. Keep a single decision file of source documents, dated quotations, adviser responses and unresolved questions. The checks above are a screening framework, not a title certification or a substitute for Monaco-specific advice.
