1. Structural System:
(1) Bolt Connections: For space cabins composed of multiple modules, it is necessary to have professionals check the bolt connections of key structures regularly (e.g., once a year) to ensure they are not loose and to tighten them if necessary.
(2) Rust Prevention: Inspect the metal frames (if exposed or in the foundation part) for rust and apply anti-rust paint in a timely manner if rust is found.

2. Electrical System:
(1) Regularly check the wiring in the distribution box to ensure it is secure and free of any burnt smell.
(2) Check the operation of the smart home system (such as smart lighting, temperature control, and security) to ensure it is functioning properly and update the software and firmware in a timely manner.
(3) Solar System (if applicable): Regularly clean the surface of the solar panels to maintain high efficiency in power generation; check the operation status of equipment such as inverters. It is recommended to have an annual inspection by professionals.

3. Water System:
(1) Regularly clean the water tank (especially the storage type) and filters.
(2) In winter, if the house is located in a cold area and is not heated, it is crucial to completely drain the water from the pipes to prevent the pipes and equipment from freezing and cracking. This is of utmost importance!
(3) HVAC System (Heating, Ventilation, and Air Conditioning):
Follow the equipment manual to clean or replace the filters of the air conditioning and fresh air systems.
Check if the outdoor unit of the air conditioner (if present) is blocked by debris and ensure good heat dissipation.
