Construction project management in Carouge
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
In Carouge, a municipality of apartment buildings, HMG Construction Management SA manages flat renovations, works on whole blocks and fit-outs of premises. Owner, managing agent or co-ownership, you can hand it the costing, the tenders and the running of the site, and where needed the plans and the permit application, which the firm files as a registered MPQ agent.
Your building work in Carouge
Carouge is densely populated. Its OCSTAT profile shows 23,050 residents at the end of 2025 on 270 hectares, or 8,547 residents per square kilometre. The table of buildings by municipality counts 1,142 residential buildings at 31 December 2025. Only 189 are single-family houses, about one in six. The other 953 hold several dwellings.
A good part of the stock is also old. 441 buildings predate 1946, nearly four in ten, and 201 were built after 2000. In Carouge, work therefore mostly takes place in an occupied building, sometimes an old one, with neighbours, a régie (managing agent) or a PPE (co-ownership), and rules specific to housing. Renovating a flat, redoing the facade or roof of a block, fitting out a shop unit or an office floor are the usual cases.
Local services are listed on the official Carouge website (in French).
Permits in Geneva
In a residential block, the LDTR, the Geneva law on demolition, conversion and renovation of housing, governs works carried out in dwellings. It has to be taken into account from the study stage, on top of the permit procedure itself, described on the page on permit types. With 441 buildings from before 1946, the asbestos, PCB and lead survey before works also concerns many Carouge projects. Our guide to building permits and procedures in Geneva goes through these points one by one.

How HMG manages your project in Carouge
The appointment can take two forms. HMG handles everything, meaning the plans, the permit application, filed as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals), and the management of the works. Or your architect designs the project and obtains the permit, and HMG takes over the file at that point and builds the project with them.
In a block, the difficulty lies less in the works than in organising them. Working hours, use of the stairwell and lift, water shut-offs and removal of rubble all have to be agreed with the régie or the PPE. HMG settles these matters before the site opens, informs the occupants, then coordinates the contractors week after week while checking quality and invoices.

Frequently asked questions
Are there single-family houses in Carouge?
Few. OCSTAT counts 189 of them among 1,142 residential buildings at the end of 2025, about one building in six. The rest are buildings with several dwellings.
Does the LDTR apply to my flat in Carouge?
The LDTR governs works in the dwellings of residential buildings. In a municipality where 953 of 1,142 buildings hold several dwellings, the question arises for a large share of projects. The firm checks this at the study stage, before pricing.
