Common Patterns

Check If Player Is Home

        local houseInfo = HousingUI.GetCurrentHouseInfo()
        if houseInfo then
            print("House:", houseInfo.name)
        end
    elseif HousingUI.IsPlayerInHouse() then
        local owner = HousingUI.GetHouseOwner()

end

Place a Decoration

local function PlaceDecoration(catalogItemID)
    if not HousingUI.IsHousingModeActive() then
        HousingUI.EnterHousingMode()
    end
    
    local current, max = C_HouseEditorUI.GetPlacementLimits()
    if current >= max then
        print("Decoration limit reached:", current, "/", max)
        return
    end
    
    C_HouseEditorUI.PlaceObject(catalogItemID)
end

Browse Catalog

local function BrowseCatalog()
    local categories = C_HousingCatalog.GetCategories()
    for _, cat in ipairs(categories) do

        if catInfo then
            print("Category:", catInfo.name)
            local items = C_HousingCatalog.GetItemsInCategory(cat)
            for _, item in ipairs(items) do
                local info = C_HousingCatalog.GetItemInfo(item)
                if info then
                    local owned = C_HousingCatalog.IsItemOwned(item)
                    print("  -", info.name, owned and "(Owned)" or "")
                end

Gotchas & Restrictions

12.0.0 only — The entire housing system is new in Patch 12.0.0. APIs may evolve in subsequent patches.
Mode requirements — Must call HousingUI.EnterHousingMode() before using editor functions.
Placement limits — Each house has a decoration cap. Check with GetPlacementLimits().
Expert vs Basic mode — Expert mode allows full 3D positioning; basic mode uses simplified snapping.
Own house only for editing — Cannot edit decorations in someone else's house.
Layout compatibility — Layouts may not load correctly if decorations have been removed from the game.
Neighborhood initiatives — Shared community goals; progress is collective, not individual.
Hardware events — Purchasing catalog items requires user interaction (hardware clicks).
