What to look for on a Lisbon apartment viewing — a buyer's checklist

A property viewing in Lisbon is the last moment when you’re seeing the apartment with your own eyes and asking your own questions. Once you’re back at home, every decision is made on photos, second-hand information, and what you remember. International buyers in particular tend to view properties in compressed three-day trips, see eight in two days, and then can’t remember whether the kitchen window faced the courtyard or the street.

This checklist is what we run through on a viewing with clients. It’s structured so you can use it on your phone or printed out, and it covers what to look at, what to ask, and what the answers usually mean. It’s written for Lisbon apartments — the most common case — and includes the local quirks (Pombaline buildings, condomínio dynamics, AL restrictions) that international checklists miss.

Before you arrive

A few minutes of prep changes what you’ll notice when you’re actually inside.

Re-read the listing on the way

Photos are flattering — wide-angle lenses, daylight pumped, clutter cropped out. Re-read the listing on the metro and write down three things to verify:

1. Does the apartment actually have the area it claims (you’ll pace it)?
2. Does the orientation match what the photos suggest?
3. Are the views in the photos viewable from the apartment, or only from the building’s rooftop?

Check the neighbourhood at the right time

If the viewing is at 11am on Saturday and you’ll be living there year-round, walk the street at three different times before you commit: weekday morning, weekday evening rush, weekend night. Lisbon’s noise profile changes dramatically — a Bairro Alto street that’s serene on Sunday morning is unbearable on Friday night. A Príncipe Real café-terrace street might be lovely at 8pm and a delivery truck thoroughfare at 7am.

Bring tools

• Phone with camera, voice notes, compass app
• Tape measure — a 5m metal one
• Plug tester if you want to be thorough (€10 on Amazon)
• Water bottle — viewings stretch in summer

Walking up to the building

Most of what you’ll learn about a Lisbon apartment, you learn before you reach its door.

The street

• What’s directly opposite? A taxi rank, a bar, a school, a building site, a tourist restaurant with a 11pm closing time? Each carries a noise/disturbance profile.
• What’s the surface? Pombaline cobble (calçada portuguesa) is beautiful and noisy — drag-a-suitcase noisy. Smooth tarmac is rare in central Lisbon.
• Parking situation? Most of central Lisbon is permit-only zones (zona de estacionamento condicionado). The apartment will need either a registered parking lugar or you’ll be paying €60–€120/month for a spot.
• Bins (contentores) — where are they? Right outside the door is a smell problem in August.

The building’s external state

• Façade condition — flaking paint, exposed brick, signs of recent restoration? A façade restoration is a common condomínio assessment and can cost €5,000–€20,000 per unit depending on building size.
• Windows on neighbouring flats — uniform or each different? Uniform suggests an active condomínio that enforces standards. Each different suggests a hands-off condomínio.
• Building entrance — is the front door secure, in good condition, with a working intercom?
• Heritage status — is the building listed as património (heritage protected)? A blue plaque, a register number on the façade, or the words “imóvel de interesse público” anywhere on documents means renovations need câmara approval and you can’t change windows, façades, or sometimes interior layouts.

The lift (or lack of)

• Walk to it. Press the button. Listen.
• Old lift, noisy = condomínio assessment for replacement coming. A new lift in a Lisbon building costs €25,000–€60,000 split among the owners.
• No lift in a five-storey Pombaline is fine if you’re 40 and healthy. Less fine at 70, with a buggy, or carrying weekly shopping in summer.
• Wheelchair accessibility — almost no pre-1990s Lisbon building has it.

Inside the apartment

First three minutes — trust the instinctive read

Walk in. Don’t ask anything. Just walk through every room slowly. Note:

• Light — does daylight reach the back of the apartment?
• Smell — damp? Cooking from neighbours? Sewage?
• Sound — can you hear the street? Neighbours? The lift?
• Temperature — cold? Warm? The same as outside (suggests no insulation)?

Write these down before the agent gives their pitch. Your first three minutes are the most honest reading you’ll do all day.

Light and orientation

• Stand by each main window at the time you’d actually live there. Is the room bright? Glaringly bright? Dim?
• Check the compass app to verify orientation matches the listing.
• Look at neighbouring buildings — what’s their height? A south-facing flat that’s overshadowed by a 6-storey building 10m away is effectively north-facing.
• Note the windows themselves — single or double glazed? Wooden frames or modern PVC/aluminium? Old single-glazed wooden frames are charming, leaky, and a major source of heat loss.

A useful exercise: at a south-facing window, can you see direct sunlight in the room? In any season, at any time, south-facing means real sun reaches the floor. If you can’t see the sun reaching anywhere, the building opposite is taking it.

Floor by floor

Kitchen

• State of fittings — original, dated, renovated? A kitchen renovation in Lisbon is €8,000–€25,000.
• Extractor fan — does it vent outside or recycle? Lisbon kitchens often vent through a building duct that may or may not be working.
• Gas or electric hob? Gas is more common in older buildings; safety check the certificate is valid (annual requirement).
• Counter space — sufficient for actual cooking, or for show?
• Cupboard inside — open one. Mould? Damp? Smell?

Bathrooms

• How many? A T2 with one bathroom is workable but tight. A T3 with one bathroom is a daily logistics problem.
• Window or no window? A windowless casa-de-banho needs strong mechanical ventilation; otherwise expect persistent damp.
• State of tiling and grout — original or recent? Grout discolouration around the shower is a sign of long-term moisture.
• Water pressure — turn taps on. Slow trickle means old pipes, common in pre-1990s buildings.
• Hot water source — esquentador (gas heater), termoacumulador (electric tank), central building system? Each has a different cost profile.

Bedrooms

• Window properly opens and closes, in every bedroom. Old wooden frames can warp.
• Wardrobe space — built-in (roupeiros) or you’ll need to buy?
• Noise — Lisbon bedrooms facing the street can be loud. Bedrooms over a bar or restaurant kitchen extractor are very loud.
• Heating — is there any? Lisbon apartments often have no heating at all and run electric heaters in winter at considerable cost.

Living room

• Layout — can it actually fit your furniture? Bring a tape measure for awkward dimensions.
• TV/cable point location — sometimes only in one corner of the room, dictates layout.
• Connection to kitchen — open-plan, sliding door, separate room?

Storage and additional spaces

• Arrecadação (storage room) — listed separately. Where is it? Building basement is normal. Check it actually exists and is accessible. Buyers occasionally discover the deeded arrecadação has been informally given to another unit years ago.
• Marquise — enclosed balcony. Common in Lisbon; counts as living space if formally licensed, otherwise as a grey-area extension. Was the marquise on the original plans or is it an unlicensed enclosure?
• Terraço (terrace) — is it private to the apartment, or shared with the building? A 30m² private terrace is a major asset; a shared 30m² terrace is much less so.

Structural and condition checks

Look for these in every room — they’re the things sellers paint over:

• Diagonal cracks in walls — possible structural movement. Hairline cracks at corners are common (Lisbon’s seismic baseline). Diagonal cracks across mid-wall are not.
• Water stains on ceilings — usually from the flat above. Ask if there’s been a repair.
• Fresh paint in patches — what’s underneath?
• Damp bloom along bottom 30cm of walls — rising damp in older buildings. Treatable but expensive.
• Bubbling paint — moisture trapped behind plaster.
• Doors that don’t close flush — settlement, often historic and stable, occasionally not.
• Floor levels — older Lisbon buildings have unmistakably wonky floors. Slight wonkiness is character; balls rolling across a room is structural.

Pombaline-building signals — what to check specifically

If you’re viewing an apartment in a Pombaline building (built after the 1755 earthquake reconstruction, mostly in Baixa, parts of Chiado and Bairro Alto, sometimes labelled “edifício pombalino” in the listing), there’s a specific set of things to verify:

• The gaiola pombalina — the timber lattice frame within the masonry walls. Tap the internal walls: a hollow sound is the timber frame, a solid thud is more recent masonry. The gaiola is what makes these buildings seismically resilient; later renovations that cut through it (to enlarge a doorway, to install a wet room) can compromise the structure.
• Original wooden floors on diagonal joists — the diagonal arrangement is a Pombaline signature. If the floor has been replaced with concrete-and-tile, the load distribution has changed and any settlement you see is more concerning.
• Sash windows (janelas de guilhotina) — original Pombaline sashes are a heritage feature. They’re often leaky and inefficient, but you can’t always replace them — heritage protection rules in some buildings forbid changing window style.
• Wrought-iron balconies with original Pombaline scrollwork — listed feature, can’t be removed.
• Building classification — is the building on the património municipal register (CML’s SIPA database)? Heritage-listed Pombaline buildings have planning constraints that significantly limit what you can change inside and out. Your lawyer should pull the building’s classification status as part of due diligence.
• Settlement vs structural movement — Pombaline buildings have settled visibly over 270 years. Wonky floors, doors not flush, hairline corner cracks — all normal. What’s not normal: diagonal mid-wall cracks, bowing walls, recently-appeared cracks (paint splits across them), or floors that have moved noticeably in the last few years (ask the seller).
• Roof and chimney condition — the original Pombaline roof was timber-framed with terracotta tiles. Replacements have happened (often badly) and current condition varies enormously.

If a Pombaline building has recently been “renovated” by a developer flipping flats, ask exactly what was done. Aggressive renovations that strip out the gaiola or replace original timber floors with concrete decks have, in some Baixa buildings, created structural problems that take years to surface.

The infrastructure

• Electrical box — open it (politely, with the agent watching). Is it modern with circuit breakers, or 1970s fuses? An electrical rewiring is €5,000–€15,000.
• Quadro eléctrico — labelled circuits suggest a recent renovation or thorough installation.
• Gas pipes — copper modern, galvanised old.
• Water meter location — sometimes inside the apartment, sometimes in the building common area. If inside, you’re responsible for visible access.
• Internet readiness — most central Lisbon buildings now have fibre-ready installations. Ask which providers serve the address (MEO, NOS, Vodafone, NOWO).

Air conditioning and heating

• Existing units? Check make and age. Mitsubishi/Daikin inverter splits are reliable; old window units are noisy and inefficient.
• No A/C at all? Common, especially in older buildings. Installation requires condomínio approval if you need external units on the façade — and some Lisbon buildings will refuse.
• Underfloor heating — premium feature, mostly in newer developments and high-end renovations.

The common areas

Often skipped on a viewing, and a mistake. The common areas tell you what the condomínio is actually like.

• Stairwell — clean? In good repair? Recent paint? A neglected stairwell with peeling walls means the owners aren’t paying for upkeep.
• Hallway smell — gas? Damp? Bins? Tobacco from a neighbour?
• Letterboxes — labelled with current names or peeling stickers from 2008? Indicator of building turnover.
• Bicycle storage or pram storage — relevant if you have either
• Communal terrace or roof access — does the apartment have access? Is it shared with the whole building or restricted?

What to ask the agent

These questions are best asked at the viewing, with the agent present, and noted. If the answer comes back “I’ll have to check” — make sure they do.

About the building

1. What’s the monthly condomínio fee?
2. What’s the current fundo de reserva balance?
3. Are there any planned works (obras planeadas) approved by the condomínio assembly?
4. When was the last AGM and what was discussed? (Ask for the acta — minutes — through your lawyer.)
5. Is the building 100% paid up, or are some units in debt to the condomínio?

About the apartment

6. When was the apartment last renovated, and what was done?
7. Has there ever been a water leak, structural repair, or insurance claim?
8. Why is the seller selling? (Often informative — divorce, inheritance, emigration, financial pressure all push for different negotiation positions.)
9. How long has it been on the market? (Months on portals is a negotiation lever.)
10. Is the price negotiable? (Always yes in Portugal. Ask anyway — sometimes the answer reveals seller flexibility.)

About the licensing

11. Is there a valid licença de utilização?
12. Has the apartment been altered from the original plans? (Marquises, partition changes, kitchen relocations all need to be on the licensed plans.)
13. Is alojamento local registered on this unit? Either you’re inheriting an active short-let licence — possibly valuable — or you’re inheriting a property where the condomínio has been fighting one.
14. Is the unit in a building where AL is restricted or banned? Lisbon has multiple zones with restrictions (Alfama, Mouraria, Castelo, Madragoa, Bairro Alto, Bica). The alojamento local situation is complex and changing.

Documents to ask for

If you’re seriously interested, ask the agent to forward the following — your lawyer will need them anyway:

• Caderneta predial (tax registration document)
• Certidão permanente (Land Registry record)
• Licença de utilização copy
• Certificado energético copy
• Ficha técnica de habitação (if post-2004)
• Last 12 months of condomínio actas

If the seller’s side resists or stalls on any of these, that’s a meaningful signal. See the key property documents to check before buying for what your lawyer will check in each.

After the viewing

Within an hour of leaving, while it’s fresh:

• Record voice notes of your reactions. Detail you forget in 24 hours.
• Score the apartment on the criteria that matter to you (light, layout, area, condition, price). A consistent scoring rubric across viewings stops you confusing “the last one we saw” with “the best one”.
• Photos with annotations — every problem area, every question mark.
• Sketch the floor plan if you can. Useful for furniture-fit decisions later.

If you’re seeing more than three properties in a day, this discipline is critical. Otherwise everything blurs.

When to walk away at the viewing

Some signals are bad enough that you can decide on the day:

• Strong damp smell that the agent dismisses (“it’s just from being shut up”)
• Fresh-painted patches the agent can’t explain
• The licença de utilização question gets vague or evasive answers
• The condomínio fee is dramatically higher than expected for the building
• A clear unlicensed extension (a marquise built in 2015 with no permit, a kitchen moved without câmara approval)
• A property listing that doesn’t match what you’re seeing (different layout, different area, different orientation)

Don’t talk yourself into something where the bones are wrong. A different apartment will come up.

Then — what we do next

If a property survives the viewing, our usual sequence is:

1. Lawyer engaged the same day if not already retained, and the document pack goes straight to them. See working with a Portuguese lawyer when buying property in Lisbon for the engagement process.
2. Offer prepared based on the listed price, the apartment’s condition, and the market for comparable Lisbon stock. We don’t usually offer the asking price — but the discount varies by neighbourhood and seller motivation.
3. CPCV drafted by the seller’s side, reviewed by your lawyer. The CPCV is the legally binding contract — once signed, you’re committed. Get the legal review right.
4. Document due diligence in parallel with CPCV negotiation. Bad title, missing licences, condomínio debt — your lawyer is checking for all of it.

The viewing is the last unrushed moment. Use it.
