After receiving the building permit decision, you have 3 years to start construction work – but before the construction site gets busy, there are several formal steps required by construction law for every investor. For a modular home, the order of these steps determines whether you can complete the entire investment in 89 days.
Key Takeaways
- A building permit only becomes legally effective 14 days after it has been delivered to all parties – construction work cannot legally begin before this period expires.
- Notification to the relevant building supervision authority about the start date of works must reach the PINB at least 7 days before the planned start – omitting this obligation qualifies the construction as unauthorized building.
- For a modular home, the foundation and module production in the factory run in parallel, so formalities after receiving the permit – appointing a site manager, construction logbook, notifying the PINB – must be handled immediately to avoid delaying the schedule.
- A surveyor must mark out the building’s outline on the plot before the foundation is laid, and after construction is completed, prepare an as-built survey – both services are arranged by the investor independently or with the help of the manufacturer.
- A modular home from PARTNER can be legally occupied within 14 days of submitting the notification of completion of construction, provided that the as-built documentation and installation acceptance protocols are complete.

I have a building permit, what’s next?
A building permit is an administrative decision issued by the competent authority – the district governor or city mayor – which authorizes the commencement and conduct of construction work in accordance with the building design. The document itself does not initiate construction. Before crews enter the plot, the investor must fulfill a series of obligations directly resulting from the Construction Law.

Step 1 – Check when the permit decision becomes final
The building permit decision becomes final 14 days after its delivery to all parties involved in the proceedings. Only a final decision grants the right to legally commence work.
If any party – e.g., a neighbor – files an appeal, the decision is not final until the appeal is resolved by a higher-level authority (Voivodeship Building Supervision Inspectorate). Before signing a contract with the manufacturer, check if your building permit is already final. You verify this with a “final” stamp on the document or by inquiring at the district office.
Step 2 – Appoint a construction manager
For the construction of a single-family home requiring a permit, a construction manager is mandatory. This is a person with construction qualifications to manage construction works in the appropriate specialty – for a residential home, these are structural and building qualifications.
The construction manager is responsible for:
- compliance of construction with the building design and regulations,
- safety and health protection on the construction site,
- maintaining the construction logbook,
- securing the construction area,
- reporting any irregularities to the investor and supervisory authorities.
The construction manager does not have to be employed by the home manufacturer – it can be a person indicated by the investor. For modular homes from PARTNER, the company assists in organizing a construction manager if the investor does not have their own contact. This is a real time-saver, as finding a qualified manager on your own in popular locations can take several weeks.
Step 3 – Obtain and stamp the construction logbook
The construction logbook is an official document in which the progress of construction works is recorded. Without a construction logbook, it is not possible to legally carry out work for a permitted construction.
The construction logbook is obtained from the district starosty office or city hall appropriate for the plot’s location. It costs a dozen or so zlotys. The competent authority stamps the construction logbook upon its issuance – only a stamped logbook has official validity.
The first entry in the logbook is made by the construction manager – it is a statement of assuming the responsibility for managing the construction. Each subsequent entry concerns the progress of works, visits by the supervision inspector, and any deviations from the design.
Step 4 – Notify the competent authority of the start date of works
Before the actual commencement of construction works, the investor is obliged to submit a notification of the intended start date of works to the relevant building supervision authority – the District Building Supervision Inspectorate (PINB).
The notification must be submitted at least 7 days before the planned start date of works. The notification should include:
- a statement from the construction manager confirming acceptance of the duty to manage the construction,
- a statement from the investor’s supervision inspector (if appointed by the investor),
- information regarding safety and health protection (BIOZ plan) – if required.
The 7-day deadline is non-negotiable. Construction of a house started without submitting the notification is unauthorized building, even if the building permit is valid.
Step 5 – Ensure the construction site is marked
In accordance with the provisions of the Construction Law, before commencing construction, an information board must be placed on the plot. The board includes:
- type of construction work,
- address and plot number,
- building permit number,
- investor and construction manager details,
- emergency phone numbers.
The board is hung by the construction manager. Its absence may result in comments from the building supervision inspector during site inspections.
Step 6 – Site and foundation preparation – in parallel with module production
This is where the actual house construction begins. For a modular home, site and foundation preparation takes place in parallel with module production at the PARTNER factory. This mechanism allows the entire investment to be completed in 89 days.
What needs to be organized on the plot:
- Surveyor and building demarcation – before the foundation is laid, a surveyor marks the building’s outline on the plot according to the site development plan. Without this step, it’s unclear exactly where to place the foundation. The cost of demarcation is 500–1,500 PLN depending on the location.
- Foundation – a modular home is lighter than a traditional brick house, so a foundation slab is often sufficient instead of deeper footings. Laying a foundation slab for a house of 80–120 m² takes 2–4 weeks and costs approximately 20,000–40,000 PLN.
- Utility connections – check if electricity, water, gas, and sewage are connected to the plot. Initiate connection procedures with utility providers in parallel with foundation preparation. The waiting time for an electrical connection is 2 to 8 weeks – if you start this procedure after the house assembly, you will unnecessarily delay the final inspection.
- Construction site access – modules are transported by flatbed trucks up to 3.5 m wide and 14 m long. The access road and entrance to the plot must accommodate this. A road that is too narrow or soft, unpaved ground is a common reason for delivery delays.

Building supervision during modular home construction
The District Building Supervision Inspector (PINB) has the right to inspect the construction site at any time. The inspector checks:
- whether construction is being carried out in accordance with the building design,
- whether the construction logbook is being properly maintained,
- whether the construction manager is present on site,
- whether the construction area is properly secured.
If the inspector finds an irregularity – they may issue an order to suspend works. For modular home construction, the risk of irregularities is lower than for traditional construction, as most work is performed in the factory under constant quality control, not on the construction site.
Advice from a PARTNER company specialist
“After receiving a building permit, investors often waste time because they don’t know what to do next. Notification to the PINB, construction logbook, manager – all this must be ready before the module transport trucks arrive. We’ve seen situations where the foundation was ready, the modules arrived, but the investor hadn’t yet submitted the notification to building supervision. Assembly had to be postponed by a week because work could not formally begin.
When building with PARTNER, we provide the investor with a specific list of steps with deadlines – who, what, and when needs to be done after receiving the permit. We help find a construction manager and coordinate connection procedures. The investor approves the design and receives the keys. The rest is on us.”

When can you move into your new home? Completion of construction and acceptance
After all works are completed – module assembly, finishing, installation connections – the construction manager prepares a statement of completion of construction and compliance with the design. The investor submits a notification of completion of construction to the PINB.
The notification should include:
- a statement from the construction manager,
- geodetic as-built survey (commissioned by a surveyor),
- installation acceptance protocols (electrical, gas, ventilation).
If the PINB does not raise an objection within 14 days – you can legally move into the building. For a PARTNER modular home, this entire stage, from assembly to acceptance, takes 2–4 weeks.

FAQ – Frequently Asked Questions
What to do after receiving a building permit for a modular home?
First, check if the building permit decision is final – 14 days must pass from its delivery to all parties. Then, appoint a construction manager, obtain a construction logbook from the district office, and submit a notification to the PINB at least 7 days before the planned start of works.
Is a construction manager required for modular home construction?
Yes – building a single-family home with a permit requires a manager with qualifications to manage construction works in the structural and building specialty. For modular home construction, PARTNER assists in finding a qualified manager.
How much time do I have to start construction after obtaining a permit?
Construction law gives the investor 3 years to start works from the day the building permit decision became final. If you do not start construction within this time – the permit expires.
What is the notification of the start date of works and where should it be submitted?
It is a document that the investor submits to the District Building Supervision Inspectorate appropriate for the plot’s location. The notification must be received at least 7 days before the planned start date of construction works.
Can building supervision inspect modular home construction?
Yes – the District Building Supervision Inspector has the right to inspect the construction site at any time. They check the compliance of works with the building design, the status of the construction logbook, and site security. For a modular home, most production takes place in the factory, so the scope of on-site inspection is limited.
When can you move into a modular home after assembly?
After assembly and finishing are complete, a notification of completion of construction is submitted to the PINB along with the manager’s statement and a geodetic survey. If the inspection does not raise an objection within 14 days – you can legally move into your new home.
Is a surveyor needed for modular home construction?
Yes – an authorized surveyor marks the building’s outline on the plot before the foundation is laid (demarcation) and prepares a geodetic as-built survey after construction is completed. Both documents are required in accordance with construction law regulations.
Does PARTNER handle formalities after receiving a building permit?
PARTNER coordinates the entire process: provides the investor with a schedule of formal steps, helps find a construction manager, and organizes connection procedures. The investor approves the design and participates in the acceptance – the manufacturer handles the rest.
