Distinguish tax licensing from the casita’s physical cost schedule

Arizona’s Department of Revenue publishes Tucson licensing and local tax information. Use that resource for the applicable account questions, and separately verify land use and property-specific requirements. Arizona Department of Revenue Tucson profile.

Define the property study

A casita renovation may include a small kitchen, cooling equipment, courtyard work, and utility connections shared with the main dwelling. Document which spaces each system serves. If the owner occupies the main house, identify that fact before the provider prepares a whole-parcel estimate.

Records that resolve the main questions

A scoping example

A contractor installs a cooling unit in the guest casita and modifies a shared electrical service. Provide the equipment invoice and electrical scope separately. The casita’s guest-only use does not establish that the entire service upgrade serves only guests.

Illustrative documentation scenario; not a completed client study or a savings estimate.

Does a city tax account determine the rental share of the property?

No. The account concerns operations. Give the preparer the layout, actual use, and supported costs to evaluate the property allocation.
