Staircase renovation in Lausanne: A comprehensive guide for property owners

The staircase is the backbone of your building.1 °C and a climate marked by 53 frost days per year, thermal comfort and sealing of this area are crucial.

An old staircase suffers from temperature variations and moisture transfer between floors, which can accelerate the deterioration of paints and coverings. Renovating this area helps improve sound insulation and limit cold drafts from unheated zones.

The timing is strategic to minimize inconvenience. It is advisable to choose moderate seasons to facilitate the drying of materials.

A well-planned renovation not only allows for modernizing the general aesthetics but also integrates low-consumption LED lighting systems, thus reducing long-term condominium charges.

In a condominium (PPE), the decision is made at the general assembly, often after identifying signs of obvious wear or regulatory compliance needs.

The renovation project strongly depends on the desired quality level and selected materials.

For floor coverings, you have the choice between complete replacement or restoration of old materials like natural stone or solid wood, which are very common in Lausanne's architecture.

Choosing materials resistant to heavy traffic is essential to ensure the longevity of the investment. Lighting options must also be studied precisely: installing motion detectors allows for optimized energy management while securing residents' paths.

An essential point concerns compliance with safety standards for railings and handrails. If existing elements no longer meet height regulations, structural modifications will be necessary.

It is strongly recommended to anticipate fire safety requirements, particularly regarding apartment doors and emergency lighting, right from the design phase. These safety elements, although technical, contribute to the overall value of the building.

Phasing by floor can be a practical solution to keep the building occupied while works take place in common areas, thus avoiding temporary relocation of residents.

The real estate stock in Lausanne, with about 24% single-family homes, offers a great diversity of construction eras. For buildings constructed before 1990, special attention must be paid to the potential presence of hazardous materials.

Before any major intervention, an asbestos diagnostic is mandatory, as this material was frequently used in tile adhesives, mastics, or insulating elements of old staircases.

Ignoring this risk can lead to significant delays and major additional costs related to specialized asbestos removal measures.

Older buildings often have obsolete electrical networks that are wise to modernize during painting or refreshment work. Thermal insulation of staircases is another major issue: in period buildings, thermal bridges at landings and entrance doors are common.

Working on airtightness without compromising natural ventilation is a technical challenge for professionals in the Canton of Vaud. Furthermore, Lausanne relies on the Architectural Census of the Canton of Vaud to identify heritage elements.

If your building is listed, specific conservation constraints will apply to original woodwork, ironwork, and floor coverings, limiting your renovation choices.

However, as soon as the work affects the external appearance, building dimensions, or if the building is protected, the situation changes. In such cases, you must follow the simplified building permit procedure.

It is always recommended to consult the municipal urban planning department before incurring any expenses to confirm the need for a formal application.

Built heritage is protected by federal, cantonal, and communal inventories.

If your building is listed in the Architectural Census of the Canton of Vaud, any modification must be discussed with the competent authorities to preserve the historical integrity of the property.

This can concern railings as well as apartment doors or floor materials. Never assume permission for modification. A written inquiry to the commune is the safest method to obtain official confirmation on how to proceed.

This preventive step ensures your design choices will not be blocked later by an order to restore the premises.

Although some energy transition measures may benefit from cantonal or federal aid, it is essential to follow the order of procedures: the aid application must imperatively be submitted and validated before the actual start of work.

Any commencement of work before receiving a written agreement generally cancels your right to subsidies. Regularly check updated programs with competent cantonal bodies.

Tax-wise, renovation and maintenance work can, under certain conditions, be deducted from your taxable income.

Expenses that serve to maintain the value of your property are considered deductible maintenance costs, while those that increase its value may be treated differently.

It is strongly advised to keep all detailed invoices and have clear quotes drawn up by local companies. Consult your tax advisor to optimize the impact of these investments on your tax return.

In condominiums, do not forget to request the renovation fund, which is the preferred financial instrument to cover these common expenses.

The success of a staircase renovation lies in following a logical sequence of steps. Once authorizations are obtained and quotes validated, the site usually begins with the protection of common areas and access to apartments.

The preparation phase includes removing old coverings and restoring surfaces (walls, stairs). If electrical work is planned, it is carried out at this stage before any painting.

Coordination between different trades, such as electricians, painters, and carpenters, is crucial to avoid unnecessary overlaps.

It is wise to plan work outside of periods of extreme cold, although Lausanne experiences demanding winter temperatures.

Drying plasters and paints requires a stable ambient temperature; frost days can significantly slow down these steps if the building is not properly heated or ventilated. Phasing is a proven method to maintain resident movement.

By completing one floor after another, you limit the impact on the occupants' daily life. Once finishing work is completed, a formal project acceptance must be carried out to check the quality of execution before final payment of invoices.

Avoiding classic mistakes helps secure your renovation project in Lausanne. Never neglect to request multiple detailed quotes to compare services fairly.

Check that each company has valid civil liability insurance to cover any damage caused to common areas during construction.

It is not advisable to order materials without verifying their compliance with current safety standards, particularly regarding slip resistance for stairs. Finally, do not underestimate the time required for administrative coordination with other co-owners.

Here is an essential checklist before you start : 1. Have you checked if your building is listed in the cantonal architectural census? 2. Was the renovation decision formally validated in the condominium assembly? 3.

Have you included fire safety requirements in your specifications? 4. Do the companies consulted understand the access constraints for residents? 5. Have you budgeted for technical contingencies related to hidden networks? 6.

Have drying times been included in the project schedule?
