How to make a click to be owner door?

I'm making a hotel type thing and I want to make it so once a player clicks a door they own it and they can open and close it whenever they want. I also want to make it so that it dosen't kill other players they just can't get in and so that a player can only claim one room per server. I'm pretty bad at this stuff so please tell me where to put the scripts and stuff too. Thank you.

Try out my owner-part script, this should work if you put the script in a part.

I just wrote this so I don't know what the errors/down-sides of using this is yet. I hope this works for you!

local Players = game:GetService("Players")

local OwnablePart = script.Parent
local ClickDetector = Instance.new("ClickDetector")

local ToggleCollision = function(Part)
	if Part.CanCollide == false then
		Part.CanCollide = true
		Part.Transparency = 0
	else
		Part.CanCollide = false
		Part.Transparency = .5
	end
end

ClickDetector.MouseClick:Connect(function(Player)
	if Player:FindFirstChild("OwnsADoor") then
		local OwnsADoor = Player["OwnsADoor"]
		if OwnsADoor:IsA("ObjectValue") and OwnsADoor.Value == OwnablePart then
			ToggleCollision(OwnablePart)
			print("This door is yours, toggling the door...");
		end
	else
		for _,OtherPlayer in pairs(Players:GetPlayers()) do
			if OtherPlayer ~= Player and OtherPlayer:FindFirstChild("OwnsADoor") and OtherPlayer["OwnsADoor"].Value == OwnablePart then
				print("You do not own this door.");
				return
			end
		end
		local OwnsADoor = Instance.new("ObjectValue")
		OwnsADoor.Name = "OwnsADoor"
		OwnsADoor.Value = OwnablePart
		ToggleCollision(OwnablePart)
	end
end)
