Construction project management in Perly-Certoux
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
HMG Construction Management SA manages building work in Perly-Certoux, for a flat in a block as well as for a house. An independent Geneva firm founded in 2014, it prepares the plans and the permit application as a registered MPQ agent, prices the work, obtains competing bids from contractors and runs the site.
Your building work in Perly-Certoux
Perly-Certoux is a modest-sized municipality. The municipal profile compiled by OCSTAT records 3,294 residents at the end of 2025 on 254 hectares, or 1,299 people per square kilometre. It belongs to the left-bank sector between the Rhône and the Arve.
The cantonal table of buildings counts 367 residential buildings there at 31 December 2025. Unusually for a place of this size, single-family houses are not in the majority. There are 158 of them, against 209 buildings holding several dwellings.
Most of the stock is of intermediate age. 78 buildings predate 1946 and 48 were built after 2000. The other 241, close to two thirds, fall in between. For an owner this means homes that have seen some use, where pipework, sanitary fittings and finishes need redoing, sometimes in a co-owned building where each decision is discussed with the other owners.
The official Perly-Certoux website (in French) gives the contact details of the town hall.
Permits in Geneva
Redoing a flat in a multi-dwelling building calls for two checks. The first concerns the LDTR, the Geneva law that governs work inside dwellings in residential blocks. The second is about hazardous substances, the subject of the cantonal page on renovating, converting or demolishing safely.
Our guide to building permits and procedures in Geneva explains the order in which to deal with these points and who files the application.

How HMG manages your project in Perly-Certoux
The appointment can take two forms. In the first, HMG leads the project from the first survey to handover and files the permit application as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals). In the second, your architect deals with design and permit, then HMG takes over the file and manages the works together with them.
In a multi-dwelling building, coordination is what matters most. The firm informs the régie (managing agent) or the co-owners, sets working hours and access, sequences the trades without idle time and protects the common areas. You receive a detailed budget before signing with contractors, then a regular statement of committed spending.

Frequently asked questions
Is Perly-Certoux mostly houses?
No. According to OCSTAT, 158 of the 367 residential buildings are single-family houses and 209 hold several dwellings. Apartment renovation is therefore just as relevant there as house renovation.
Who informs the managing agent or the co-owners before work starts?
The firm does this with you. It passes on the specification, the programme and the site hours, and remains the neighbours' point of contact for the whole job.
Will the firm take on a single bathroom?
Yes, as long as several trades need coordinating. A call to +41 22 552 08 22 is enough to discuss it, and you are called back within 24 hours.
