Cost Segregation for Condos and Townhomes
Practical guidance for business owners and residential rental investors.
Identify what the owner actually owns
A condominium purchase includes rights described in the governing documents, not unrestricted ownership of every amenity in the development. Distinguish the unit, any relevant common-element interest and assets owned by the association. Townhome ownership can differ from condominium ownership even when the buildings look alike. The deed and governing documents matter more than the marketing label.
Begin with legal ownership boundaries
Request the deed and relevant condominium declaration or townhome ownership documents. Identify the unit, land interest, exclusive-use areas and shared facilities. The physical appearance of a building does not determine who owns an asset for tax purposes. If an association purchases or maintains a facility, distinguish its expenditure from the unit owner's supported basis before assigning a cost to the study.
Evaluate association charges by purpose
Regular dues, reserve contributions and special assessments may pay for different things. Keep the association's explanation of the project and any cost detail. A large assessment for replacing common infrastructure is not automatically a current repair expense. Conversely, not every association payment should be added to the unit's depreciable basis. The preparer needs the purpose and ownership facts to evaluate treatment.
Reconcile unit furnishings and personal use
Separately purchased beds, appliances or electronics may already appear on the owner's schedule. Match them against the report before importing assets. Preserve the unit's actual rental and personal-use calendar, especially when the owner uses the property seasonally. Ownership of a condominium rather than a house does not remove the vacation-home rules or establish that a generated loss is currently deductible.
Illustrative decision
An owner cannot automatically add a share of the community pool's replacement cost to the unit's tax basis. A special assessment also needs analysis of what it pays for and how the payment is treated. Retain the association notice and supporting project description instead of labeling every assessment a repair.

Practical review: cost segregation for condos
A condo or townhome requires a property-specific review. The unit's name and purchase price do not establish which assets belong in a study. Your records should explain what you acquired, what you later improved, and how shared facilities relate to your ownership.
Describe the unit separately from the development
Create two lists: items inside or attached to your unit, and facilities shared across the development. Provide the governing documents and ask the provider which ownership interests require further analysis.
A listing that advertises a pool, gym, and landscaped grounds is useful context, but it is not a complete tax allocation. Ask how the report distinguishes the unit, shared property interests, and separately purchased items.
Identify your renovations
Provide invoices for work you funded, including the location, scope, completion date, and any separately acquired equipment or furniture. Explain which work the association performed and how you were charged.
An assessment labeled “capital project” may leave several questions unanswered. Obtain available project descriptions, statements, and allocation records so your preparer can evaluate the facts.
Keep rental and personal-use records together
Tell the advisor whether the unit is a long-term rental, short-stay accommodation, or a property you also use personally. Provide a dated use calendar rather than an annual percentage estimated from memory.
The IRS describes special rules for dwelling units used personally and rented in Publication 527. A study does not resolve those use questions by itself.
Compare the scope before comparing the price
Ask whether the quote covers the unit only, later improvements, furnishings, and any supported common-property interests. Confirm what the provider needs from the association and who obtains it.
If another quote appears cheaper, compare exclusions. A proposal based on incomplete ownership records may require additional work later.
Review AE's study pricing and documents checklist. Bring an organized property packet and a list of unresolved HOA questions to the initial conversation.
