Loi du 21 septembre 2006

Luxembourg law governing residential leases (bail à usage d'habitation): written form, inventory, deposit capped at two months' rent, notice periods, and rent indexation rules.

Trêve hivernale

Winter truce from 1 November to 15 March during which enforcement of eviction from a dwelling is suspended, except by court order for specific grounds.

Copropriété voting majorities

Under the 1975 co-ownership law, structural works require a three-quarter majority of the general assembly; changing the building's destination requires unanimity.

PAG

Plan d'Aménagement Général: the communal land-use plan defining zones, building coefficients and urban rules; adopted after public enquiry and ministerial approval under the 2013 planning law.

PAP

Plan d'Aménagement Particulier: a project-level plan that must be compatible with the PAG; either 'quartier existant' or 'nouveau quartier', requiring a convention with the commune for infrastructure.

COS vs CUS

COS (coefficient d'occupation du sol) equals building footprint divided by plot area; CUS (coefficient d'utilisation du sol) equals gross floor area divided by plot area.

Servitude urbanistique

A planning easement (setback, building line, height limit) recorded in the PAG or PAP that binds all subsequent owners and runs with the land.

Permis de construire

Communal building permit required for new construction, substantial alteration, change of use and certain demolition; explicit authorisation is needed - silence does not grant it.

Certificat d'urbanisme

A non-binding information document issued by the commune stating the planning rules applicable to a specific plot; it does not authorise works.

Recours au Conseil d'État

Appeal against a building-permit refusal lodged with the administrative jurisdiction of the Conseil d'État within three months of notification; it does not automatically suspend the decision.

PEB certificate

Certificat de performance énergétique required for new buildings and for sale or rental; energy class A to I; valid for ten years under the 2016 energy-performance law.

nZEB requirement

Nearly zero-energy building standard (bâtiment à consommation quasi nulle) mandatory for new public buildings from 2021 and private buildings from 2023 in Luxembourg.

K-value

Global thermal transmission coefficient of a building envelope; new residential buildings must achieve K ≤ 0.30 W/m³K under Luxembourg PEB rules.

Glaser method

Steady-state calculation of temperature and vapour-pressure profiles through a building element to check for interstitial condensation risk; vapour barrier placed on the warm side.

Eurocode national annex

Luxembourg National Annexes (ANL) to the Eurocodes set nationally determined parameters such as snow load, wind velocity and seismic acceleration for design.

Luxembourg seismic zone

Luxembourg lies in a low-seismicity zone with design ground acceleration generally ≤ 0.04g; EN 1998-1 applies with the national annex for ordinary buildings.

Imposed floor loads

EN 1991-1-1 characteristic values: 1.5 kN/m² for residential floors, 3.0 kN/m² for stairs, 2.5 kN/m² for balconies (categories A and B).

Luxembourg geology

Luxembourg Sandstone (Lias) dominates the centre and east (Gutland); schist and quartzite form the Ardennes (Oesling); geotechnical investigation per EN 1997 precedes foundation design.

VMC heat recovery

Mechanical ventilation with heat recovery (η ≥ 80%) required for nZEB dwellings; minimum ventilation rate about 0.3 air changes per hour under EN 13141.

RGIE / AREI

Luxembourg general regulation on electrical installations: 30 mA differential protection for socket circuits, TN earthing, and inspection before energisation.

Legionella prevention

Domestic hot water stored at ≥ 60 °C and distributed at ≥ 50 °C to limit Legionella growth; dead legs and oversized tanks should be avoided.

Lift inspection

Lifts designed to EN 81-20/50 must be inspected every 12 months by an approved inspection body in Luxembourg.

Coordinateur sécurité-santé

Safety and health coordinator required under the 1994 law whenever several contractors work on a site; appointed from design phase through completion.

Smoke detector obligation

Under the 8 June 2004 law, every dwelling must have smoke detectors; common areas of apartment buildings also require detection and maintained escape routes.

Reaction to fire classes

EN 13501-1 classes A1 to F; floor coverings in escape routes must be at least Bfl-s1 and wall linings at least B-s1,d0 in common areas.

Asbestos inventory

Before renovating buildings completed before 2005, an asbestos inventory is required under the 2007 law; removal must be done by certified firms.

Ramp slope limit

Under the 2022 accessibility law, ramps in public buildings have a maximum slope of 6% (5% preferred), flights of at most 10 m, and landings of 1.5 m.

Accessible door width

Clear door width of at least 0.90 m for public buildings and 0.80 m minimum for interior doors in dwellings; threshold height ≤ 2 cm; lever handles at 1.00-1.10 m.

Accessible parking space

Minimum width 3.30 m (2.50 m plus 0.80 m transfer zone); at least one space per 50 spaces, located close to the accessible entrance.

OAI mission phases

Ordre des Architectes et des Ingénieurs-Conseils mission stages: esquisse, avant-projet, projet, dossier d'autorisation, appel d'offres, chantier, réception, defined in the architecture contract.

Marché à forfait

Lump-sum construction contract in which the price is fixed; variation claims are limited to unforeseen circumstances or client-ordered changes.

Responsabilité décennale

Ten-year liability of builders for structural and waterproofing defects; provisional acceptance starts the one-year perfect-completion guarantee.

Retenue de garantie

Five percent of the contract price retained until final acceptance; may be replaced by a bank guarantee under Luxembourg construction practice.
