Making a rented Luxembourg apartment feel like yours without breaching the lease

Almost everything worth doing to a rented flat is reversible, and almost everything that causes trouble at the exit inspection was fixed to a wall. Knowing which is which is the whole discipline.

Two documents set the boundary

Your lease governs your relationship with the landlord. A separate document, drawn up by the co-owners and administered by the syndic, governs what you may do inside the building. Most Luxembourg leases bind the tenant to respect the règlement de copropriété and any règlement d'ordre intérieur, which means agreeing to something many tenants are never shown.

Your landlord owns one lot inside that structure and cannot grant you rights the co-ownership has not granted them. This is the source of most friction: the landlord says yes, and the syndic subsequently says no, and the syndic is correct. Ask for both documents and get any permission in writing.

What is almost always fine

• Lighting. Plug-in floor and table lamps transform a Luxembourg living room in February, where a single ceiling fitting does not. Three or four sources at different heights.
• Textiles. Rugs, throws, cushions, bedding. Rugs also resolve more acoustic disputes than any amount of correspondence, particularly in converted townhouses with timber floors and little separation between units.
• Curtains, hung correctly. Inside the reveal they permanently cover glass; hung outside and above it they clear the opening entirely when open. In a dark room that difference is significant.
• Freestanding storage and shelving that leans or stands rather than fixes.
• Plants, indoors. Outdoors, check the rules on planters fixed to a railing.
• Removable adhesive hooks for lighter items, tested on an inconspicuous area first.

What needs written permission

Painting. Some Luxembourg landlords permit it and some require a return to the original colour at the end. Either way it belongs in writing, with the colour specified, because repainting an entire apartment at the exit is a substantial cost to absorb on someone else's instruction.

Anything fixed to a wall with a plug: shelving, heavy mirrors, wall-mounted televisions. The lease decides, and the practical protection is photographing each wall before and after. Filling and touching in a picture hook costs a few euros before the exit inspection and appears at contractor rates afterwards.

Replacing light fittings, changing bathroom fixtures, altering the kitchen, or anything touching a load-bearing wall or the building's common systems. These need the landlord's consent and frequently the co-ownership's, and where you do replace something, keep the original and reinstate it at the end.

What the building will refuse

The facade is almost always common property even where the balcony is for your exclusive use. That rules out awnings, satellite dishes, external air-conditioning units, and often planters fixed to railings, and in some buildings there are rules on the colour of anything visible from outside.

Storage in common areas is the other consistent prohibition: bicycles in the corridor, prams under the stairs, boxes outside the cave. These are the most commonly breached rules and the most commonly enforced, because they are visible to every other resident. Storing tyres or bicycles in an underground parking space is prohibited in many buildings for fire-safety reasons rather than aesthetic ones.

Where the building has a local à vélos, bicycles are usually required to live there rather than in the cave.

The changes that cost nothing and matter most

Three interventions do more than any purchase.

Move the furniture before you buy any. Live with the room for a fortnight and notice where you actually sit in the evening and where the light falls. Most people arrange a room the way the previous occupant did and then buy to match a layout they never chose.

Deal with the entrance. Many Luxembourg apartments have no hall, and in a heating season running October to April an entrance that has nowhere for coats and wet boots undermines the whole flat. A bench, a mat and hooks that do not require drilling resolve it.

Fix the acoustics before they become a complaint. Rugs, felt pads under furniture, a curtain across a hard wall. Noise complaints go first to the syndic, then to the owner, then to you, and a tenant with two such letters has created a problem for their landlord.

Keeping the exit in view

Everything above is easier if you photograph the apartment as you received it and keep the entry inventory accessible. Six weeks before you leave, read the entry document against the flat as it stands and make a list of the differences you can still resolve yourself.

Normal wear and tear is not chargeable, and there is no published depreciation table in Luxembourg, so the line is argued case by case. Faded paint after three years, a flattened carpet along a circulation route and yellowed silicone read as wear. A hole in plasterboard, a stained parquet panel and a damaged door frame do not. The way to keep that argument short is to have made the entry document long.

Three questions we are asked

Can I keep a pet? Building rules commonly restrict or prohibit them, and that restriction sits above whatever the landlord says verbally. Get any permission in writing and check whether it names the animal or the category.

Can I sublet a room? Frequently prohibited outright by the co-ownership, independently of what your lease permits. Short-stay letting in particular is one of the fastest routes to a formal notice from a syndic.

The rules are in French or German and I read neither. Ask the agent for a written summary covering pets, subletting, balconies, works and bicycle storage. A written answer you can point to later is worth more than a full translation you skim once.

Working with the light rather than against it

Luxembourg sits at 49 degrees north. In late December the sun rises around half past eight and sets before half past four, and a large share of days between November and February are overcast. More than any single purchase, adapting to that is what makes a rented flat feel habitable rather than temporary.

Three adjustments cost little. Position seating towards the window rather than towards a wall, since in a dark month the view out is doing more work than any object in the room. Choose pale, matt surfaces for anything large you add, because gloss reflects the ceiling fitting rather than the daylight. And place a mirror facing a window rather than facing into the room, which is the single most effective reversible change available in a north-facing space.

Where the apartment overheats in summer instead, note the distinction between internal and external shading. Internal blinds stop glare; external roller shutters, common in Luxembourg construction, stop heat before it enters. You cannot fit external shading yourself, because the facade is common property, so check what already exists rather than planning to add it.

Three questions we are asked

Can I change the light fittings? Often yes with the landlord's consent, and the practical rule is to keep the original fitting and reinstate it at the end. Anything wired should be done by a professional, and anything touching the building's common systems needs the co-ownership's consent as well.

Will the landlord mind if I paint? Some permit it and some require a return to the original colour at the end. Either way, get the permission and the colour in writing, because repainting an entire apartment at the exit inspection is a substantial cost to absorb on a verbal understanding.

How much can I reasonably spend on a rented flat? Spend on things that leave with you: lamps, rugs, textiles, freestanding storage, art. Be cautious with anything fixed, anything cut to size, and anything that only fits this particular room. The crossover point is whether it still has value in the next apartment.
