Triplexes: Ownership and use map

Identify the owner, user and payer for the property and its components. Map the three units and common-area costs before assigning figures to an individual unit.

Preparation resource. Record completion does not determine eligibility, deductions or tax savings. Ask your qualified tax professional to resolve the facts and applicable rules.

What this file should establish

Match title, agreements and cost records. Explain personal use, tenant-owned property and shared systems where relevant. Legal title and tax reporting can require professional interpretation; preserve the documents rather than assuming the answer.

Map the three units and common-area costs before assigning figures to an individual unit.

A situation to work through

The owner upgrades common stairs and one unit's kitchen in the same contract.

For this situation, start with unit inventory. Identify the period and legal owner before combining it with the other records. Keep the original source and explain any adjustments in a separate reconciliation.

Review point

Separate location and function within the contractor package.

An item visible at the property is assumed to belong to the landlord.

Question for the reviewer

Who owns and reports each material component and what use facts matter?

Expected handoff

An owner-user-payer map with questions marked.

Separate facts supported by documents from estimates and unresolved assumptions. Assign each missing item to a responsible person and a date. Send the reconciliation alongside the source references so the reviewer can trace each conclusion.

Use the following primary guidance to frame the questions. The worksheet organizes facts; it does not replace analysis of the relevant year, ownership, elections or state treatment.
