Why issue closes nothing
Three reasons, all legal.
The permit is open to challenge. Third parties may contest it before the administrative courts within a defined period.
The starting point of that period depends on a formality falling to the holder, the display, covered in the article on display and certificate.
The permit lapses if works are not begun within a set period, covered in the article on lapse and extension.
Issue therefore opens a phase; it does not close one.
| Obligation | Who bears it | Timing |
|---|---|---|
| Display of the permit | The holder | From issue |
| Observing the appeal period | The holder | During the set period |
| Starting within the validity period | The holder | Before lapse |
The three obligations that follow
They fall on the holder, not on the municipality. The display obligations rest with them.
Display the certificate at the site, visibly and legibly from the public highway.
Comply with the conditions of the permit, any departure exposing the works to a stop notice.
Begin works within the period, failing which the permit lapses by operation of law.
The first obligation is the one believed optional, and that is a significant error of analysis, as the next section explains.
The window of risk to cross
A counterintuitive point worth stating plainly. A permit once issued is not yet final.
One might think it better not to display, so as not to draw neighbours' attention.
The opposite is true. The appeal period runs from display. So long as display has not taken place, the window in which the permit can be challenged does not close.
Not displaying means extending your exposure indefinitely, while also breaching an obligation.
Displaying early and properly is therefore the most effective measure of legal security, and it costs nothing.
The decisions not to take too early
Four commitments to defer until the appeal period expires, where the programme allows. They concern orders and irreversible works.
Ordering irreversible works, notably earthworks and foundations.
Long-lead orders committing substantial sums with no possibility of cancellation.
Resale or letting of the property on the basis of the permitted scheme.
Firm contractual commitments with contractors, or at least making them conditional on the absence of appeal.
This precaution does not remove the risk, an appeal remaining possible within the period, but it limits the financial consequences.
What remains possible during this period
Three things, useful for not losing time. They are done as soon as the decision is issued.
Preparing the tender and analysing the offers.
Obtaining the other permits required, covered in the article on other permits required.
Finalising the financing and the production information.
The appeal period is therefore not lost time, provided the programme has been built accordingly, as the article on the timeline of a project explains.
