Houses are maps in PMU which every character is given automatically. Players can enter houses in housing centers. Each house can be mapped to the player's desire and its size is customizable. Whether the house's purpose is for mapping practice or just for fun, players can use their home as a way creating their own domain. Players do not have access to all of the attributes that staff who can access the map editor do. Users are also only allowed to map in their own house rather than in every map in-game unless they have the appropriate staff rank.
Every player in PMU owns their own house; therefore, anyone can enter the mapping contests held by staff members. Mapping could be considered its own mini-game in PMU, as everyone has their own taste and style in house decor.
House Commands[]
House commands are used to modify one's house. If a player also holds down their left 
key and right clicks at the same time inside their own house, they can teleport to the right clicked tile.
Certain commands can only be accessed via certain Explorer Ranks. This gives users incentive to pursue missions.
Normal Rank[]
/edithouse- Opens the house editor in your house./leavehouseor/lh- Leaves the current house you're in./housekickor/hk- Kicks someone from your house./emptyhouseor/hkall- Kicks everyone from your house./houseentrance- This allows the player to change the spawn point of their house to the tile they are standing on. Costs 500 Poké./houseroof- This opens up or closes the roof of the player's house. Weather will be disabled and the time will always resemble day when closed. Costs 500 Poké.
Bronze Rank[]
/housenotice- Similar to/housesign, except it is not a blocked tile, allows the black text to be customized, and a player stands on the tile to receive the note. Base price is 600 Poké, with each character written adding 10 Poké./houseshop- Allows the player to create a shop tile. Costs half the price the shop tile is selling for./housesound- Allows the player to add a sound tile. Costs 500 Poké./housesign- Allows the player to place a sign in their house. The number of characters in the sign affects the cost of the sign, adding 10 Poké per character.
Silver Rank[]
/houselight- Adjusts the darkness of the house. Costs 400 Poké./houseweather- Changes the weather inside the player's house. Costs 300 Poké.
Gold Rank[]
/houseexpand- The player's house can be extended by one tile. A 50x50 house costs 1,100,000 Poké if done from the default house size. However, one doesn't need to expand to the maximum size in one go - rather, they can expand by smaller increments instead if they've got a small budget. Width expansions are 7,500 Poké (Price doubles per width after each expansion) and height expansions are 10,000 Poké per tile.
Trivia[]
- The only way to expand one's house before the summer of 2012 was by winning a mapping contest.
