Completing construction of a modular home requires fulfilling formalities in the form of a completion notice or obtaining an occupancy permit decision. The choice of procedure depends on whether the investor plans to move into the building before all work specified in the project is finalized.
Key Takeaways
- In the case of standard single-family home construction, the investor typically submits a completion of construction notice, which is a significantly faster procedure than obtaining a full administrative decision.
- Final documentation must be prepared by individuals with construction qualifications in the appropriate specialty, which ensures that the completion of the building structure complies with safety standards and the project.
- The building supervision authority has exactly 14 days to raise an objection to your notice; if the deadline passes without a response, you can begin using the building structure.
- It’s worth remembering that you can choose an occupancy permit instead of a completion of construction notice, which is necessary when you plan to use the building before completing all work covered by the project.
- Every completion of construction notice for a structure must include a post-construction inventory, which is regulated by the geodetic and cartographic law, confirming, among other things, the building’s location on the plot.
What is completion of construction and an occupancy permit?
Completion of construction is a factual and legal state in which construction work has been finalized according to the project, allowing for notification of completion of construction to the appropriate authority. An occupancy permit is an administrative decision issued by building supervision, which is mandatory only in strictly defined cases or at the explicit request of the investor.
Formal completion of investment in 2026 – completion of construction notice
In 2026, every investor building a single-family home must formalize the completion of work before moving into the property. Although modular homes are built quickly, building law treats them the same as masonry buildings. To legally begin using the structure, you must submit documentation to the District Building Supervision Inspectorate.
Most people building homes up to 70m2 or larger residential structures use the notification procedure. This means that after completing work, you submit a completion of construction notice, and if the authority does not raise an objection within 14 days, you can legally move into the home. The lack of objection is referred to as “tacit consent” for use of the building.

When is an occupancy permit for a building mandatory?
Although a notice is typically sufficient for a single-family home, there are situations where a decision on an occupancy permit is necessary. This particularly applies to cases where construction was carried out based on a building permit, and the investor wants to start using part of the home before completing the whole.
Cases requiring a permit:
- Partial use – the investor wants to finish the ground floor and move in there, while the attic remains in a shell state.
- Legalization of unauthorized construction – the building was erected in violation of regulations and underwent a legalization process.
- Non-residential structures – if a modular home is to serve a commercial function (e.g., office, practice), a full occupancy permit is required.
Without obtaining this decision, commencing use of a building structure of a commercial nature is illegal. This carries high financial penalties imposed by building supervision.
Notice vs. permit – comparison of procedures
The table below presents key differences between the two paths for formally completing construction of a modular home.
| Feature | Completion of construction notice | Occupancy permit |
| Application | Standard for single-family homes | Special situations or upon request |
| Waiting time | 14 days (tacit consent) | 21 to 60 days (decision) |
| Official inspection | Possible, but not mandatory | Mandatory on-site DBSI inspection |
| Required opinions | Usually none (unless the project states otherwise) | Fire Department, Sanitary Inspectorate |
| Cost | Free (for individual investor) | May require stamp duty |
Documentation required to close construction
To effectively notify completion of work, you need to compile an extensive set of attachments. The most important is the original construction log, which documents the progress of work from the day you decided to start construction.
Key documents include:
- Construction manager’s statement of compliance of the structure’s execution with the project and regulations.
- Construction manager’s statement of compliance of the structure’s execution with the building permit conditions.
- Post-construction geodetic inventory report.
- Testing and inspection reports for installations (electrical, gas, chimney).
- Copy of the energy performance certificate for the residential building.
The construction manager must also confirm that the construction site and its surroundings have been properly cleaned and restored, including neighboring properties if they were used during module installation.
How to obtain an occupancy permit step by step?
If your situation requires an administrative decision, the process is more rigorous. An application for an occupancy permit is submitted after obtaining opinions from the Fire Department and the State Sanitary Inspectorate. These services have 14 days to take a position.
After submitting the application, the authority schedules a mandatory inspection. The inspector checks the building structure’s compliance with the construction project and analyzes whether the building poses a threat to the life or health of residents. If the inspection reveals significant deviations from what the construction project assumed, a refusal decision is issued, and the investor may be fined.
Advice from a PARTNER company specialist
“Many people building modular homes forget that notification of completion of construction must occur before actually moving in. At PARTNER, we help clients verify the completeness of the construction manager’s statement of compliance of work, which eliminates the risk of penalties for illegal use of the structure. Remember that proper geodetic documentation is half the success at the office.”

Penalties for investors for illegal use of a building – failure to notify completion of construction
Commencing use of a home without fulfilling formalities is an offense. Building supervision then imposes financial penalties, the amount of which is calculated based on a statutory formula. The calculation takes into account the product of the fee rate, the building structure category coefficient, and the building structure size coefficient.
For a single-family home (category I), these penalties can range from several to several tens of thousands of zlotys. It’s therefore worth waiting the required 14 days from the date of submitting the notice before you decide to officially commence use.
Construction notice vs. completion notice – common mistakes
A common mistake by investors is confusing the concept of construction notice (made before starting work) with the concept of completion of construction notice (after finishing work). These are two separate processes. Another problem is the lack of current entries in the document that is the construction log, which prevents the manager from issuing a reliable statement about the execution of the building structure according to the project.
With modular homes, investors sometimes assume that since the building arrived “ready,” formalities are minimal. The truth is that foundations, utility connections, and site development are subject to the same inspection as in traditional construction. An application for a permit must include confirmation of acceptance of all utilities.
Why is it worth entrusting formalities to specialists?
The process of obtaining an occupancy permit can be stressful due to complexities in building law regulations. Professional modular home construction companies, such as PARTNER, offer support not only in installation, but also in preparing post-construction documentation.
By working with our experts:
- You gain certainty that the construction manager’s statement of compliance is prepared flawlessly.
- You avoid the risk of application rejection by the authority due to formal deficiencies.
- You receive complete geodetic inventory and installation reports.
- You have certainty that the building fully complies with the building permit conditions.
Summary
Proper use of a building structure begins with orderly documentation. Regardless of whether a simple notice is sufficient or an application for an occupancy permit is necessary, the key is close cooperation with the construction manager. Remember that a modular home is modern technology that deserves professional formal completion, guaranteeing peace of mind for your family for years.

FAQ – Frequently asked questions
1. Where and when should I submit a completion of construction notice for a structure?
Submit the appropriate completion of construction notice to the district building supervision inspectorate immediately after actually finalizing work. This procedure applies to investments carried out based on a construction notice and those with a permit, unless the law imposes an obligation to obtain an occupancy decision.
2. Can I move into the home if the investment requires a completion notice, but not all work is finished?
If you want to move into a residential building or a building with a residential section before completing all work (e.g., unfinished upper floor), you must obtain an occupancy permit instead of a completion of construction notice. This allows for legal partial use of the structure in accordance with the law.
3. What documents confirming completion of work must I prepare?
The investor must compile construction documentation, including the original construction log. Also important is the construction manager’s statement about completion of construction work and documentation about measurement of the building’s usable area.
4. What happens if my notice is incomplete?
If the notice is incomplete, building supervision will call on you to supplement deficiencies within a specified deadline. In such a case, the 14-day period for objection is suspended, and completion of proceedings regarding the notice will occur only after providing all required attachments.
5. What obligations does the construction manager have upon completion of construction and intention to commence use?
The construction manager, as one of the persons with construction qualifications, must confirm the building’s compliance with the project. They prepare a statement about restoring the site to proper condition and confirm parameters regarding the building’s usable area and individual installations, which is necessary for building supervision to accept the notice.
6. Will I receive any document after notifying the authority of completion of construction?
Typically, building supervision will accept the completion of construction notice without sending correspondence (so-called tacit consent). However, you can apply for a certificate of no objection to the completion of construction notice, which is often required by banks or for registration.
7. When can I submit an application for an occupancy permit instead of a notice?
You can always submit an application for a permit for occupancy voluntarily, even if such a permit is not required for your building with a residential section. This is often practiced with complex projects to have a formal decision confirming that building supervision has been fully informed about completion of construction and has accepted the technical condition.
8. How does the verification process proceed regarding a completion of construction notice?
When you submit a completion of construction notice, officials check the correctness of your construction notice against the construction project. If no violations are found, your completion of construction notice will be processed positively through the lack of an objection decision, which means that after 14 days you can legally use the property.
