Can you take a Section 179 deduction on apartment appliances and improvements?
Sometimes, but fewer apartment purchases qualify than most owners expect. The building, its structural parts and roofs or HVAC on a residential building do not qualify; appliances and other personal property can, but only if the rental is an actively conducted trade or business with enough taxable income, and individual owners also face a rule that limits Section 179 on property leased to others. Many small owners end up using regular depreciation or the de minimis safe harbor instead.
What Section 179 is
Section 179 lets you elect to deduct the cost of qualifying property in the year you place it in service instead of depreciating it. Publication 946 says that for tax years beginning in 2025 the maximum deduction is $2,500,000, reduced by the amount by which the cost of Section 179 property placed in service exceeds $4,000,000 (IRS Publication 946). For an apartment owner, the dollar cap is almost never the problem. The three hurdles below are.
Hurdle 1: is the item the right kind of property?
| Purchase | Section 179 eligible type? | Why |
|---|---|---|
| Refrigerators, ranges, dishwashers in units | Can be | Publication 946 lists property in a building that is not a structural component, such as refrigerators, as tangible personal property, and includes certain property used to furnish lodging |
| Washers and dryers you own in a laundry room | Can be | Tangible personal property |
| A new roof on an apartment building | No | Qualified Section 179 real property covers roofs only on nonresidential real property |
| New HVAC, fire alarm or security systems for the building | No | Same: these count only as improvements to nonresidential real property |
| Interior renovation of units | No | Qualified improvement property is limited to the interior of nonresidential buildings |
| The building itself | No | Buildings and structural components are not tangible personal property |
So for an apartment owner, the candidates are mostly appliances, furniture in furnished units and equipment. Roof and system replacements on residential buildings go through regular depreciation, or the partial disposition election for the old part.
Hurdle 2: the business income limit
Publication 946 says the deduction is limited to the taxable income from the active conduct of any trade or business during the year, and that you actively conduct a trade or business if you meaningfully participate in its management or operations. That income can include wages you earn as an employee. Anything disallowed carries forward to the next year.
Two questions follow. First, is your rental a trade or business at all? That depends on facts like how many units you own, how involved you are, and how regular the activity is. Second, do you have enough taxable business income that year? A building that shows a loss after depreciation does not, by itself, make room for more deductions.
Hurdle 3: property you lease to someone else
Publication 946 says that generally you cannot claim Section 179 on the cost of property you lease to someone else, and that this rule does not apply to corporations. A non-corporate owner who buys property and leases it can still qualify only if both tests are met:
- The lease term, including renewal options, is less than 50% of the property's class life.
- For the first 12 months after the property goes to the lessee, your business deductions on it (other than rents and reimbursed amounts) are more than 15% of the rental income from it.
Whether a refrigerator inside a leased apartment counts as property leased to the tenant, and whether those tests are met, is a question for your tax preparer. It is the main reason many small landlords who own buildings personally or through an LLC taxed as a sole proprietor or partnership do not use Section 179 at all.
A worked example
Example a made-up owner of a 30 unit building spends $13,800 on 12 refrigerators ($1,150 each), $7,600 on 4 laundry room washers ($1,900 each) and $88,000 on a new roof in the same year. The roof is out under hurdle 1, so it is depreciated over 27.5 years. The $21,400 of appliances passes hurdle 1. If the preparer concludes the rental is an actively conducted business and the leasing tests are met, and the owner's taxable business income is $15,000, Section 179 is capped at $15,000 for the year and $6,400 carries forward. If any hurdle fails, the $21,400 is depreciated instead, or each $1,150 refrigerator may be expensed under the de minimis safe harbor, which the IRS says allows up to $2,500 per invoice or item for taxpayers without an applicable financial statement (IRS, tangible property regulations).
How DoorKeeping keeps these purchases straight
DoorKeeping's AI bill reading codes each invoice to the right account in that property's books, with appliances, improvements and repairs kept apart and the invoice saved in documents. At year end your tax preparer gets one list per property to decide Section 179, depreciation or de minimis treatment. DoorKeeping does not make the election or give tax advice.

Questions
- Can I use Section 179 for a new roof on my apartment building?

- What is the Section 179 limit for 2025?
- Publication 946 gives a $2,500,000 maximum for tax years beginning in 2025, reduced dollar for dollar once qualifying purchases exceed $4,000,000.
- Why might a landlord not qualify for Section 179 on appliances?
- The rental may not be an actively conducted trade or business with enough taxable income, and non-corporate owners face a rule limiting Section 179 on property leased to others. Ask your tax preparer.
