In brief: An objection to a building permit in Switzerland is the legal remedy with which affected parties challenge a building application during the public inspection. The objection periods range from 14 days in St. Gallen to 30 days in Aargau, Schaffhausen and Basel-Stadt. Decisive, and wrongly presented in almost every guide: the Canton of Zurich has no objection procedure at all in the building permit process. Anyone who wants to defend themselves here must file a request for service of the decision under § 315 PBG within 20 days of the public notice and then lodge an appeal with the building appeal court within 30 days. Anyone who misses the request for service forfeits their right of appeal (§ 316 PBG).
This article explains both systems, gives the deadlines for each canton with the legal reference, sets out the appeal stages with costs and actual procedural durations, and clarifies when the paid withdrawal of an objection becomes extortion. All figures with source, as at August 2026.

1. Objection, representation, appeal: three terms that do not mean the same thing
Three terms are constantly mixed up even though they refer to different stages of the procedure. Anyone who keeps them apart immediately understands why the answer to "how does an objection work" differs from canton to canton.
Objection (Einsprache): A legal remedy against a building application, lodged with the building authority during the public inspection, that is, before the permit has been decided. This is how Zug, Aargau, Schwyz, Thurgau, St. Gallen, Schaffhausen and Basel-Stadt work.
Representation (Einwendung): The submission made in a planning procedure, for instance against a development plan or a change to the zoning plan. It is usually open to anyone, not only to affected parties, and is dealt with collectively when the plan is adopted.
Appeal (Rekurs): The legal remedy against a decision that has already been issued, addressed to an appeal body. In the Canton of Zurich this is the building appeal court in building matters, with a deadline of 30 days under § 22 para. 1 VRG.
Anyone who files an objection in the Canton of Zurich therefore files something that does not exist there. At best the letter is accepted as a request for service of the decision, at worst the deadline simply runs out.
2. The special case of the Canton of Zurich: there is no objection at all
The Canton of Zurich has no objection procedure in the building permit process. The route for affected parties has two stages.
Request for service of the decision within 20 days (§ 315 PBG). Anyone who wants to take part in the procedure asks the local building authority, within 20 days of the public notice, to serve the building decision on them.
Appeal within 30 days of service of the decision (§ 22 para. 1 VRG). Only against the building decision once it has been issued is an appeal to the building appeal court of the Canton of Zurich available. Only here is the substance argued out.
The trap lies in step one. Anyone who does not file the request for service in time forfeits their right of appeal under § 316 PBG. The decision is never served on them at all, and by the time they hear about the building project it is already legally binding. It then does not help that the impact on them would be obvious.
For clients this is the other side of the same coin: in Zurich it is settled within 20 days of the public notice who can have a say in the procedure at all. Anyone who has involved the neighbours beforehand has nothing to fear from these 20 days. How that works is described in the article avoiding objections: what really helps as a client.
3. Building notice and building profiles: how you find out in the first place
For the deadline to run fairly at all, the project has to be made visible and publicly known. In the Canton of Zurich a double system applies.
Staking out with building profiles (§ 311 PBG). The building project is marked out on the ground with profile poles and cords so that position, height and volume can be read off. The staking out must be in place by the time of the public notice and must remain standing for at least the whole inspection period. The building authority may require the profiles to stay up until the building decision.
Public notice (§ 314 PBG). The building application is published in the cantonal official gazette and in the municipality's official publication channel and is laid open for public inspection for 20 days. The deadline for the request for service runs from this publication.
Anyone who wants to know regularly what is being submitted in their municipality should subscribe to the official publication channel. Relying on the building profiles is risky, because the deadline is tied to the publication and not to visibility.
4. Objection periods compared by canton
The deadlines differ considerably. What always governs is the law of the canton where the site lies, in its version currently in force.
Canton | Remedy during public inspection | Deadline | Legal reference |
Zurich | no objection procedure, request for service | 20 days, then 30 days for the appeal | §§ 314 to 316 PBG, § 22 VRG |
Zug | objection to the municipal council | 20 days | §§ 45, 47a PBG, BGS 721.11 |
Schwyz | objection under public law | 20 days | §§ 78, 80 PBG, SRSZ 400.100 |
Thurgau | objection | 20 days | §§ 102 f. PBG, RB 700 |
St. Gallen | objection | 14 days | Art. 139 para. 3 PBG, sGS 731.1 |
Aargau | representation (Einwendung) | 30 days | § 60 BauG, SAR 713.100 |
Schaffhausen | representation (Einwendung) | 30 days, exceptionally 20 | Art. 61 f. Building Act, SHR 700.100 |
Basel-Stadt | objection, free of charge | 30 days | § 91 BPG and § 45 para. 1 BPV |
These deadlines are forfeiture deadlines. They cannot be extended, and a late submission is not dealt with, however justified the objection may be on the merits.
5. Who actually has legal standing
There is no actio popularis. Anyone who wants to defend themselves must be affected in person.
§ 21 para. 1 VRG (LS 175.2): Anyone who is touched by the order and has an interest worthy of protection in its annulment or amendment is entitled to appeal.
For building projects the Federal Supreme Court requires a particularly close spatial relationship. BGE 137 II 30 states: in the case of building projects the closeness of the relationship to the subject matter of the dispute must exist in spatial terms in particular. There is no fixed limit in metres. The widespread rule of thumb of 100 metres is not a rule of law but an aid to orientation. The Federal Supreme Court has affirmed legal standing at a distance of around 25 metres, but the decision is taken case by case and depends on how strongly the project affects the person's own property.
Tenants can also have legal standing if they are specifically affected by immissions. Anyone who is merely annoyed in general terms about the building activity, or who has a purely aesthetic concern, does not have legal standing.
6. What can be challenged and what cannot
Legal remedies are not a verdict on taste. They succeed only if a legal norm has been breached.
Can be challenged: breach of the setback rules, exceeding the utilisation ratio, the building height or the number of storeys, disregard of building lines, forest setback or watercourse space, deficiencies in access and parking, breaches of the Noise Abatement Ordinance, use that is not permitted in the zone concerned, formal errors in the procedure.
Can be challenged only within limits: integration into the surroundings and design. The aesthetic requirements of the building and zoning ordinance are justiciable, but the authority has considerable room for assessment, which the courts review with restraint.
Cannot be challenged: the mere loss of a view, provided that no corresponding easement is entered in the land register and no integration requirement is breached. Equally not: a loss of value of your own property, construction immissions during the building period as such, and the fact that you do not like the project.
Anyone who proceeds without a legal basis loses and as a rule bears the costs. That is why a level-headed preliminary review of the building application is worth it before any legal remedy.
7. The appeal stages from the municipality to Lausanne
The route through the instances is clearly regulated in the Canton of Zurich. The cost ranges are set by statute, the durations come from the published accountability and annual reports.
Stage | Deadline | Court or administrative fee | Average duration |
Request for service, municipality | 20 days from the public notice | City of Zurich CHF 50, otherwise the municipal fee schedule | runs alongside the building application |
Appeal to the building appeal court ZH | 30 days from service | as a rule CHF 500 to CHF 50,000 (§ 65a VRG) | around 4 to 5 months on average |
Appeal to the administrative court ZH | 30 days | same range (GebV VGr, LS 175.252) | around 6 months |
Appeal to the Federal Supreme Court | 30 days (Art. 100 BGG) | CHF 200 to 5,000 without financial interest, otherwise up to CHF 100,000 (Art. 65 BGG) | around 189 days |
The 12 to 36 months often quoted for the Federal Supreme Court do not match the statistics. The 2025 annual report shows an average duration of proceedings of 189 days. Anyone who exhausts the full appeal route must nevertheless reckon with two to three years, because the stages add up and the transfer of the files in between takes time.
8. What the procedure really costs
At municipal level the procedure is cheap. In the Canton of Zurich the request for service costs CHF 50 in the city of Zurich, in Basel-Stadt objections are expressly free of charge, and in the objection cantons too the first stage usually remains free of charge or very cheap. It only becomes expensive from the appeal onwards.
Court fees: § 65a para. 1 VRG provides for as a rule CHF 500 to CHF 50,000 for the building appeal court and the administrative court. In building matters there is usually no determinable amount in dispute, which is why the range is used according to effort and significance. In particularly demanding proceedings the fee can be doubled.
Lawyer's fees: Experience shows that a legal mandate for an appeal at both cantonal levels moves in the range of CHF 2,000 to CHF 5,000 for a simple submission, and considerably above that once expert opinions and several instances are added. Indicative figures, as at 2026.
Party costs: Whoever loses usually has to pay party costs to the other side. That is exactly where the real risk of a hopeless submission lies, not in the court fee.
9. How long it takes
For context: a building application without a legal remedy already takes longer in the Canton of Zurich than many expect. For the building appeal court, § 339a para. 1 PBG provides for a target deadline of six months. According to the accountability report the court meets it in around 78 percent of proceedings, with an average duration of proceedings of 4.3 months.
As a client, work with this rule of thumb: an appeal costs you half a year, taking it on to the administrative court another one, and the Federal Supreme Court a good half year again. Anyone working with construction loans and fixed-date contracts should know this timeline before filing. How long the procedure takes without a legal remedy is set out in the article how long a building permit takes.
10. May construction go ahead while the procedure is pending?
No, and that follows directly from the law:
§ 25 para. 1 VRG: The running of the appeal period and the filing of the appeal have suspensive effect.
So the running appeal period alone already blocks enforceability, not just the appeal once it has been filed. Before the deadline expires and before the decision becomes legally binding, construction is in principle not permitted. Anyone who starts anyway risks a stop-work order and, in the extreme case, an order to restore the lawful condition, that is, removal of the works at their own expense.
That is the real leverage of every objection: not winning, but time. A project that stands still for a year costs interest, inflation and often the contractor, who has meanwhile committed elsewhere.
11. Withdrawal for money: where the line to extortion runs
Withdrawing a legal remedy in return for money is not prohibited across the board. But it quickly becomes a criminal offence, and the line runs more sharply than many assume.
An agreement is permissible if it compensates a genuine, legally founded disadvantage, for instance a contribution to a noise abatement measure or to an access installation from which both sides benefit. An agreement that merely buys off the delay to the procedure, or pays for a submission that was hopeless from the outset, is contrary to public policy and void under Art. 20 CO.
It becomes a criminal offence under Art. 156 SCC where a payment is demanded for waiving the legal remedy to which there is no entitlement, and this is linked to the threat of loss caused by delay. The Federal Supreme Court has decided such a case: an objector first demanded CHF 150,000 for the withdrawal, then CHF 820,000, and threatened an appeal and construction delay. The Federal Supreme Court upheld the conviction for attempted extortion.
For clients this means: do not pay anything under time pressure and without legal review. Document every demand in writing, record which legal disadvantage it is supposed to compensate, and have the agreement reviewed before you sign. What has already been paid can be reclaimed under Art. 62 et seq. CO if the agreement is void.
12. What belongs in an objection or an appeal
A submission does not have to be elegant, but it has to be complete. These seven points belong in it:
Addressee and description of the project: authority, building application number, plot, client, date of publication.
Your legal standing: who you are and why you are affected. Position of your own property, distance, specific impact. This point decides whether the authority will consider your submission at all.
Your requests: what exactly is being asked for, that is, refusal of the permit, conditions, or amendment of specific parts.
Reasons with the legal norm: for each point name the provision that has been breached, with the section. Without a norm there is no chance.
Evidence: plans, photographs, extracts from the building and zoning ordinance and from the zoning plan, a land register extract where easements are involved.
Deadline and form: on time, in writing, signed. Where several people are affected, have all of them sign.
Willingness to negotiate: one sentence on which adjustment would settle the concern. That opens the way to a solution without proceedings.
From the client's point of view the same list is a checklist: a building application that cannot be attacked on any of these points is a good building application. How a dossier is sharpened up to that point is shown in the article from preliminary design to the building application, and the course of the procedure is explained in building application and building permit.
13. Frequently asked questions about an objection to a building permit in Switzerland
Is there an objection against a building application in the Canton of Zurich? No. The Canton of Zurich has no objection procedure in the building permit process. Anyone who wants to take part must file a request for service of the decision under § 315 PBG within 20 days of the public notice and can then lodge an appeal with the building appeal court within 30 days against the decision once it has been issued. Anyone who misses the request for service forfeits their right of appeal under § 316 PBG.
How long does the objection period run in Switzerland? It is governed at cantonal level and ranges from 14 to 30 days: St. Gallen 14 days, Zug, Schwyz and Thurgau 20 days, Aargau, Schaffhausen and Basel-Stadt 30 days. In the Canton of Zurich the deadline for the request for service is 20 days and the subsequent appeal period is 30 days. All these deadlines are forfeiture deadlines and cannot be extended.
Who may object to a building project? Only someone who is affected in person. § 21 para. 1 VRG requires the person to be touched by the order and to have an interest worthy of protection. For building projects, BGE 137 II 30 requires a particularly close spatial relationship. There is no fixed limit in metres, and the widespread rule of thumb of 100 metres is not a rule of law.
May construction take place while an objection is pending? No. Under § 25 para. 1 VRG, the running of the appeal period and the filing of the appeal already have suspensive effect. The decision is therefore not enforceable, and as a rule no construction may take place before it becomes legally binding. Anyone who starts anyway risks a stop-work order and removal of the works at their own expense.
What does an appeal against a building permit cost? The first stage is cheap: in the city of Zurich the request for service costs CHF 50, in Basel-Stadt objections are free of charge. From the appeal onwards, § 65a para. 1 VRG provides for a court fee of as a rule CHF 500 to CHF 50,000, and at the Federal Supreme Court the range under Art. 65 BGG is CHF 200 to 5,000 without financial interest. On top of that come lawyer's fees and, if you lose, the party costs of the other side. Indicative figures, as at 2026.
May money be demanded for the withdrawal of an objection? Not prohibited as such, but quickly a criminal offence. Where a payment to which there is no entitlement is demanded for waiving the legal remedy, and this is linked to the threat of loss caused by delay, that fulfils the elements of extortion under Art. 156 SCC. The Federal Supreme Court has upheld such a conviction. Under civil law an agreement is void under Art. 20 CO if it merely buys off the delay to the procedure. Anyone who cannot assess the situation should take advice before paying, for instance through independent owner's advisory.
