The ancillary costs of building a house

You're having a house built: anticipate ancillary costs

Building a house requires a controlled, planned budget. In fact, in addition to the costs associated with the house, you'll have to deal with a number of ancillary costs. Polimmo La Maison, your house builder in South Finistère, tells you about these costs that you shouldn't forget to plan for.

Land-related costs

Notary fees

 Buying a plot of land involves transfer duties (or taxes), which you need to factor into your budget. These taxes, which correspond to the notary's fees, vary depending on whether you are buying from a private individual or a professional. 

If you are dealing with a private individual, the plot is subject to registration duties. Since the Macron law of 2016, these transfer duties for a new-build purchase correspond to 0.715% of the sale price, inclusive of tax, in most French departments. Added to this are the notary's fees, as well as the property security contribution and the costs associated with formalities (obtaining cadastral fees, for example). The notary's fees can therefore represent a total of 7 to 8% of the land's sale price. 

If you buy from a professional, he or she is liable for VAT, which means a reduction in costs of up to 2 to 3% of the selling price of the plot. 

The cost of demarcating and servicing the plot

If your plot of land is "off the grid" or outside an allotment, you will need to have it serviced and marked out, which will cost you. To have it connected to the various networks (electricity, gas, water, telephone, etc.), it will cost you around 10 to 20% of the price of the plot. You will also need to have a boundary survey carried out, at a cost of between €1,000 and €1,500. 

Another possible expense is a soil survey to check the stability and homogeneity of the land, at a cost of between €1,500 and €3,000. 

If you buy from an estate agent, don't forget their commission, which is usually between 5 and 7% of the sale price. 

The ancillary costs of your loan

A mortgage also generates additional costs, such as guarantee fees, death and disability insurance, administration fees, etc. Ask your lending institution to estimate the amount. 

Costs during construction

Development tax

Once the building work has started, you will be liable for the taxe d'aménagement (formerly the taxe locale d'équipement since 2012). It is calculated as follows

Development tax = Surface x Fair market value x Rate set by the local authority 

PAC, or Collective Sanitation Contribution

If your municipality is connected to the mains sewerage system, it will set the amount of the PAC. If it is not, you will be responsible for installing a non-domestic sewage system, which will cost you a minimum of €10,000. 

Building damage insurance

You become the owner when you have your house built. You then need to take out damage and construction insurance, which gives you the same protection as the ten-year guarantee. Polimmo La Maison offers you this insurance, included in the price, and on attractive terms, negotiated for our entire customer portfolio.
