If I go to Home Depot and spend $500 on a new bathtub, a door, paper-towels, a new screwdriver set, windex, and valve stems for a faucet; would I break these down into supplies, cleaning and maintenance, and repair with separate entries?

@Justin HerringtonWhile Thorold does not give a maximum occupancy per dwelling unit in a direct manner, it appears to define any building providing lodging to more than four (4) occupants as a boarding house:“boarding house” means a building in which lodging is provided for more than four (4) persons in return for remuneration or for the provision of services or for both and in which the lodging rooms do not have both bathrooms and kitchen facilities for the exclusive use of the individual occupant;In turn, they restrict a rooming house or lodging house (but never marry definitions to that of the boarding house) as follows:Where a dwelling unit contains rooms intended to be used in conjunction with a rooming house or lodging house, the occupants may share a single bathroom provided that: (1) not more than nine (9) persons occupy the dwelling unit; (2) for each additional nine (9) persons or part thereof, there shall be an additional toilet, handwash basin, bathtub or shower; and (3) access to the bathroom can be gained without passing through: (a) a habitable room of another dwelling unit; or (b) an open area, which is not normally heated during the period of the year which heat is required by article 2.22.3 of this by-law.So, it appears to come down to whether boarding houses are permitted where you property is located (and whether they need to be specifically licensed), unless your building would be seen as a non-conforming duplex.This is the question, I believe Thomas was asking.

Here is what we put in our move out letter, which may be helpful to build on:Specifically, here's a list of items you should thoroughly clean before vacating:[ ] Floors[ ] sweep/mop laminate floors[ ] vacuum carpets and rugs (shampoo if necessary)[ ] mop kitchen and bathroom floors[ ] Walls, baseboards, ceilings, and built-in shelves[ ] Kitchen cabinets, countertops and sink, stove and oven--inside and out [ ] Refrigerator--clean inside and out, empty it of food[ ] Bathtubs, showers, toilets, and plumbing fixtures[ ] Doors, windows, and window coveringsPlease don't leave anything behind--that includes bags of garbage, clothes, food, newspapers, furniture, appliances, dishes, plants, cleaning supplies, or other items that belong to you.For move in, put all info in the rental agreement.  

Every once in awhile I have a bathtub with the jets.

The 2nd bathtub I hope to be able to reglace and safe, new vanity and sink. 

Here in Tampa Bay, you can barely find a standard bathtub, so you're probably going from spending $150 on a bathtub to $500.

How much was it to replace a bath tub/shower or just a stand alone tub or walk in shower?

Only thing I wanted to do was redo the bathtub and add blinds, but wanted to start renting so those become expenses and tax write offs.

Primary bedroom includes a beautiful full bathroom with large bath tub.

ie, replacing a damaged bathtub?
