Environmental protection

Living in a society requires that certain rules of "savoir vivre" are followed, many of which are dictated by common sense and basic notions of public-spiritedness: respect for others, respect for public and private spaces... When needed, municipal bylaws exist to remind individuals that neglecting to respect the environment and living conditions shall not be tolerated and that such behaviour may even be liable to penalties.
Breaches of regulations, whether with respect to hygiene, waste management, works, noise or dog droppings, not only constitute nuisances for fellow citizens, but also an additional cost to the community.

Improvements to Housing Conditions

For works to proceed, they must be issued a permit establishing that they comply with regulations for the land use plan and the protected historical areas. The latter includes the entire historic city centre. It is mandatory to connect to the main sewer and to restore façades every 10 years. You will be personally notified by mail of this, and it affects all parts of the street, whether visible or not. Depending on the condition of the coatings, it may vary from basic cleaning to complete repair. As for the colour chosen, it must respect Saint-Germain-en-Laye’s palette.

Pollutions and Nuisances

  • Be mindful of noise! Outside of the following time periods -- business days (8:30 a.m. to noon and from 2:30 p.m. to 7:30 p.m.), Saturday (9 a.m. to noon and from 3 p.m. to 7 p.m.), Sunday (10 a.m. to noon) – all noise produced by do-it-yourself activities, amplified music (stereos and instruments) and the use of loud engines is prohibited. The following are also considered punishable: works involving renovations or household equipment liable to mar the acoustic environment of local residential premises, the continual barking of pets, “modified” scooter exhaust pipes and disturbance of the peace at night, including during parties and receptions.
  • A fantastic view... It is prohibited to beat rugs and to hang laundry to dry in windows that can be seen from the street.
  • Be wary of pests: Stray animals, pigeons, rodents and insects may carry germs and cause harm to buildings, and are attracted by litter and stagnant water. Exercise vigilance.
  • Water has a cost...: Even though water is not in short supply in Saint-Germain, moderate your  consumption and don’t contribute to polluting the water table: use biodegradable washing powder, clean your vehicle or have its oil changed on the sites specially set up to collect waste water  polluted by hydrocarbons (garages, service stations, car wash stations...). You may consult the water analysis that is regularly displayed in the entrance of the City Hall and in the Administrative Centre.
  • ...and so does energy: The addition of sound and thermal insulation may, in some cases, benefit from financial assistance. Please review the PACT Yvelines - 3, rue Porte de Buc - 78000 VERSAILLES. Tel.: 01 39 07 78 51 -

  • Give yourself some air: Properly maintain your heating equipment and your vehicles. Equip them with the most recent pollution-reducing devices.

Sweeping and Snow Clearance

City inhabitants are obliged to sweep (or, if applicable, clear snow from) the sidewalks opposite the shops, workshops, buildings or properties they occupy. Sweeping (or snow clearance) must be done before 7:30 a.m. between April 1 and October 1, and before 8 a.m. between October 1 and April 1. Local residents may be held liable for any accidents occurring as a result of their negligence.

In the Event of Snowfall: Sweeping in Front of your Door

While it is the City's responsibility to provide street snow clearance for the commune, it is up to the inhabitants to clean (or to have cleaned) the sidewalks in front of their home (Bylaw of 1933). In fact, the landlord or tenant is held liable in the event of an accident occurring on his or her doorstep. Snow removal is an action of good citizenship that enables everyone to travel easily and safely. The Bylaw of 31 July 1933 is very clear and, most importantly, is still enforced today: 

"Inhabitants are hereby directed to sweep, arrange for sweeping and weed the sidewalks in front of shops, workshops, buildings or properties for which they are landlords or tenants. Sweeping shall take place every day before 7:30 a.m. from April 1 to October 1, and before 8 a.m., from October 1 to April 1. 
In the event of snow, ice or thawing, landlords or tenants (...) are under an obligation to carry out one or several additional cleanings of sidewalks, to clear snow in piles, to break ice on streams and, in the event of black ice, to spread sand or ashes on these sidewalks."

During incidences of snowfall, it is recommended to sweep snow just after it has fallen in order to avoid having it freeze on the sidewalk.


Organic Waste Collection

Burning of household and similar waste, building waste and vegetable waste is prohibited (Decree of 8 March 2012). You may either drop off your plant waste (grass, leaves, various plants, branches, etc.) at the waste reception centre on rue Frédéric Bastiat or have them removed every 15 days (every week in the rue du Pontel sector) by the “plant waste removal” service.

  • Maintenance of green spaces;
  • Some landscaping works are subject to special requirements. Please make the necessary inquiries before proceeding;
  • Trees or other vegetation that jut out over the public highway must not impede the free flow of pedestrians, cars or trucks, public lighting, road signage or the various overhead lines. Ensure that vegetation that juts out is trimmed under proper safety conditions. Your liability is at stake. If you must cut down a tree, request written approval from the Environment department;
  • If your garden is maintained by a specialised company, the company must provide for the removal of plant debris and must not deposit them on the public highway;
  • The use of lawnmowers, chainsaws and other noisy devices used in gardens is authorised (municipal bylaw of March 30, 1993) within certain time intervals: business days (8:30 a.m. to noon and from 2:30 p.m. to 7:30 p.m.), Saturday (9 a.m. to noon and from 3 p.m. to 7 p.m.), Sunday and holidays (10 a.m. to noon).


Precipitation Measurement Station

The communal precipitation measurement station is located in the new cemetery. A daily reading is sent to Paris and Versailles.
