ancillary provision

An ancillary provision is an additional clause in an administrative act or contract that supplements, restricts, or imposes conditions on the main content. In real estate law, it is most commonly found in building permits, development agreements, and official approval notices. Ancillary provisions may take the form of conditions, requirements, time limits, or reservations of revocation, and are legally binding.

Types of ancillary provisions in real estate law

In public building law, there are primarily four types of ancillary provisions (regulated in § 36 VwVfG):

• Condition: The administrative act only takes effect or terminates if a specific event occurs (e.g., a building permit subject to a positive species protection assessment).
• Requirement: The beneficiary is imposed with an obligation that must be fulfilled independently (e.g., the obligation to restore a portion of the land to its original state after completion of construction work).
• Time limit: The administrative act is valid only for a specific period.
• Reservation of revocation: The authority reserves the right to revoke the approval under certain circumstances.

Ancillary provisions may also be of a private-law nature-e.g., in sales contracts as suspensive or resolutive conditions (Sections 158 et seq. BGB). A condition precedent makes the conclusion of the contract contingent upon the occurrence of a specific event-classically, a bank’s commitment to provide financing. If the condition is not met, the purchase contract has not taken effect.

Ancillary Provisions in Building Permits

Building permits in Bavaria are frequently subject to conditions that must be fulfilled by the builder. Typical examples include: requirements regarding sound insulation (e.g., soundproof windows in noise protection zones), rainwater infiltration (swales or green spaces instead of fully sealed surfaces), the proportion of green space, or proof of parking spaces. These conditions are an integral part of the permit and must be strictly adhered to-otherwise, the permit may be revoked or a fine imposed.

It is important for developers and investors to factor in ancillary provisions early in the project calculation, as they can result in significant additional costs. A soundproofing requirement may necessitate the installation of soundproof windows costing several thousand euros per unit; a parking space requirement may force the construction of an expensive underground garage.

An objection can be filed separately against an ancillary provision deemed unlawful-that is, independently of the main administrative act. This is important to know, because anyone who wishes to use the permit but challenge a specific condition can do both at the same time.

Ancillary Provisions in Private-Law Purchase Agreements

In private purchase law, ancillary provisions are referred to as conditions. A real estate purchase agreement can, for example, be concluded subject to the condition precedent of the bank’s financing commitment: if the financing fails, the agreement does not take effect. Conditions resolutives are also possible-for instance, if a right of first refusal is exercised: if the right of first refusal takes effect, the original purchase agreement is automatically void without the need for a termination agreement.

Due to the formal requirements of real estate purchase law (§ 311b BGB), such conditions must be notarized. A condition agreed upon separately-for example, via email or verbally-is invalid and, in the worst case, can jeopardize the entire purchase contract.

Implications for Buyers and Investors

For real estate buyers, the ancillary provision regarding the financing contingency is particularly relevant. Anyone who purchases a property before the bank has definitively approved the financing bears the risk of being unable to rescind the purchase agreement in the event of a rejection. A clearly worded financing contingency-notarized as a condition precedent-resolves this problem: The purchase agreement only becomes effective once the financing commitment has been granted.

Practical Tip for Property Owners in Nuremberg and Franconia

For construction projects in the city of Nuremberg and the surrounding area, we regularly see that building permits are subject to extensive conditions-particularly regarding drainage, landscaping, and soundproofing. Anyone who receives a permit should carefully read all ancillary provisions and document their fulfillment. We recommend consulting an architect or a specialist attorney for construction law in a timely manner to avoid surprises upon completion.

For buyers who wish to include a financing contingency in the purchase agreement, we are happy to serve as intermediaries and coordinate the appropriate wording with the notary.

Frequently Asked Questions

Can I challenge a condition in a building permit?

Yes, conditions can be challenged separately without jeopardizing the building permit as a whole. The objection must be filed with the relevant district office or municipal authority within the statutory deadline (in Bavaria, typically one month after notification).

What happens if I do not comply with a condition in the building permit?

The building authority may revoke the building permit, impose fines, or order the demolition of the building. In the worst case, an order to remove the structure may be issued for conditions that violate building regulations.

Is a collateral provision in the purchase agreement binding?

Yes, provided it is notarized, a collateral provision-such as a suspensive or resolutive condition-is legally binding on both parties to the contract. If the condition is met (or not met), this has an immediate legal effect on the purchase agreement.

What is the difference between a condition and a requirement?

A condition makes the occurrence or continuation of a right dependent on a future event-if the event does not occur, there is no right (or it expires). A requirement, on the other hand, grants the right immediately but simultaneously obligates the beneficiary to perform a specific action. If the requirement is not fulfilled, the administrative act may be revoked-but it is not invalid from the outset.

How do I handle complex ancillary provisions in a building permit?

If a building permit is subject to extensive or costly conditions, builders should weigh three options: First, fulfilling the conditions if they are reasonable and technically feasible. Second, appealing individual conditions if they appear unreasonable or are based on incorrect factual assumptions-in this case, the building permit remains valid otherwise. Third, engaging in dialogue with the building authority to find a modified solution that achieves the objective of the condition through alternative means. In Nuremberg and the districts of Erlangen-Höchstadt and Nürnberger Land, we frequently encounter conditions regarding parking space documentation, infiltration systems, and noise protection measures for new construction projects near industrial zones or major thoroughfares. Those who seek a discussion with the building authority in a timely manner-that is, well in advance of submitting the application-can avoid many of these requirements through adapted planning. Upon request, we can provide contacts to experienced real estate attorneys and architects who routinely assist with such coordination processes.
