- [How to rent out your container - a guide for owners](https://maszbox.pl/en/blog/jak-wynajac-swoj-kontener-poradnik-dla-wlasciciela.md): The build has finished, the company has moved to a warehouse or you simply no longer need so much space, and the container stands empty on a yard or plot. It brings in no income, yet it still needs looking after.
- [Container on a plot - notification or building permit?](https://maszbox.pl/en/blog/kontener-na-dzialce-zgloszenie-czy-pozwolenie.md): You want to put a container on your plot to keep tools, equipment or things that do not fit in the house. A truck with a crane brings the container, sets it down in an hour and that is it. It is easy to skip the question of formalities.
- [What container size to choose? 10, 20 or 40 feet](https://maszbox.pl/en/blog/jaki-rozmiar-kontenera-wybrac-10-20-czy-40-stop.md): You are browsing container listings and see labels like "20 ft", "40'" or "40 HC". You do not know what will fit in them or whether the container will even stand on your plot.
- [Owning a container - how to adapt it and look after it](https://maszbox.pl/en/blog/kontener-na-wlasnosc-jak-go-przystosowac-i-o-niego-dbac.md): You have bought a container and it is already standing on your plot or yard. It is suitable for storing things straight away, because it is a tight, lockable box. After the first winter, however, you may find that water collects on the ceiling, the doors have started to stick and rust has appeared at the corners.
- [How to sell a warehouse - documents, tax and the listing](https://maszbox.pl/en/blog/jak-sprzedac-magazyn-dokumenty-podatek-i-ogloszenie.md): You have a warehouse you no longer need: the company has moved, the business has closed or the building has been standing empty for months. You look for a guide and find texts about selling flats that do not answer the questions specific to a warehouse.
- [Small warehouse for an online shop - how to set it up](https://maszbox.pl/en/blog/maly-magazyn-dla-sklepu-internetowego-jak-go-urzadzic.md): Your online shop's stock no longer fits in the flat, so you have rented a small warehouse: a few or a dozen or so square metres, a concrete floor, a door with a code. Guides to organising a warehouse describe halls with pallets and inventory management systems, while you have a box in which you are not even allowed to drill.
- [Self storage - what is it and how does it work?](https://maszbox.pl/en/blog/self-storage-co-to-jest-i-jak-dziala.md): Your things no longer fit at home or in the office, and while looking for somewhere to put them you keep coming across the term "self storage". It sounds like an ordinary warehouse, but you do not know how it differs, how much space you need or what to look at when choosing.
- [Container on a house building site - tools and materials](https://maszbox.pl/en/blog/kontener-na-budowie-domu-narzedzia-i-materialy.md): You are building a house and every day you carry tools to the plot and back, because there is nowhere to leave them. Bags of cement and adhesive lie under plastic sheeting, and every evening you wonder whether everything will still be there in the morning.
- [Warehouse or container for rent - which to choose?](https://maszbox.pl/en/blog/magazyn-czy-kontener-na-wynajem-co-wybrac.md): You have things you have nowhere to keep: stock from an online shop, furniture during a renovation or equipment that comes back into use once a season. Search results give you two options, a warehouse and a container, and most guides are written by companies that sell one of them.
- [Insuring belongings in a rented warehouse](https://maszbox.pl/en/blog/ubezpieczenie-rzeczy-w-wynajetym-magazynie.md): You have rented a warehouse or a self storage box and moved furniture, cardboard boxes, equipment or stock from your shop into it. You have home insurance, so you assume your things are covered.
- [How to secure a storage unit against theft: proven methods](https://maszbox.pl/en/blog/jak-zabezpieczyc-komorke-lokatorska-przed-kradzieza.md): Doors, locks, alarms, a bike anchor and insurance: what actually protects a storage unit from burglary, and what to check before you rent or buy one.
- [Storage unit construction: types, materials and what to look out for](https://maszbox.pl/en/blog/zabudowa-komorki-lokatorskiej-rodzaje-materialy.md): Brick, modular or plasterboard? Storage unit construction types compared on ventilation, privacy, durability and cost.
- [Storage unit rental contract: what it must contain (and what gets forgotten)](https://maszbox.pl/en/blog/umowa-najmu-komorki-lokatorskiej-co-musi-zawierac.md): Which clauses a storage unit rental contract has to include, what ready templates leave out and what to check in the space before you sign.
- [Selling a storage unit step by step: documents, costs and taxes (2026)](https://maszbox.pl/en/blog/sprzedaz-komorki-lokatorskiej-krok-po-kroku.md): When a storage unit can be sold separately from the flat, how to separate it step by step, what the whole procedure costs and which taxes you pay.
- [How much does it cost to rent a storage unit? 2026 prices and how to find one safely](https://maszbox.pl/en/blog/ile-kosztuje-wynajem-komorki-lokatorskiej.md): What storage unit rental prices depend on in 2026, how private rental differs from self-storage, and when buying pays off.
- [How to earn from spare space: basement, garage, plot and more](https://maszbox.pl/en/blog/zarabiaj-na-wolnej-przestrzeni.md): You have a basement where the same boxes have been standing for years, a garage no car ever drives into, or a piece of land nobody visits. This space costs you rent, property tax or simply upkeep, and brings in nothing.
- [How to rent out a commercial unit fast and stop losing money](https://maszbox.pl/en/blog/jak-szybko-wynajac-lokal-uzytkowy.md): Got an empty commercial unit that has been standing unlet for months?
