Can Buildings Be Depreciated? | The Rules Owners Trip On

Most income-producing buildings can be depreciated over set recovery periods, while land can’t and improvements use their own lives.

You buy a building, you start renting it out or running a business from it, and then tax season arrives. Somewhere in the paperwork you’ll see “depreciation,” and it can feel like a mystery deduction that either saves you money or gets you in trouble.

Depreciation isn’t a loophole. It’s a method for recovering the cost of long-lasting property over time. If your building is used to earn income, the rules often let you deduct a slice of that cost each year. If you mix up land and building, pick the wrong recovery period, or start too early, the numbers can fall apart fast.

This article shows what qualifies, what does not, and how owners usually keep the recordkeeping clean.

What Depreciation Means For A Building

Depreciation treats a building as something that wears out. Roofs, finishes, systems, and layouts age. The tax rules let you recover your cost by taking annual deductions across a set number of years.

The IRS walks through the core depreciation rules, including MACRS and real property recovery periods, in IRS Publication 946 (How To Depreciate Property).

Two guardrails keep the whole topic grounded:

• You depreciate your cost (basis), not today’s market value.
• You depreciate the building, not the land under it.

Can Buildings Be Depreciated? For Rentals And Businesses

Most buildings can be depreciated when they’re used in a trade or business or held to produce income, like rent. Three checks cover most cases:

• Use: business use or income-producing use.
• Placed In Service: ready and available for that use.
• Determinable Life: a structure that wears out over time.

A personal residence that’s only for personal living does not generate depreciation. If part of a home is used for a qualifying purpose, depreciation may apply to that part, based on allocation and the specific use rules.

Land Is Always The Carve-Out

Land never gets depreciated. When you buy real estate, you split the price between land and building, then depreciate only the building portion. The IRS makes this point bluntly in its Depreciation FAQs (PDF), along with practical ideas for allocating value like assessor ratios.

If you skip this step and depreciate the full purchase price, you’ve built a problem into every year’s return.

Placed In Service Is Not A Guess

Depreciation starts when the property is ready and available for its intended use. That might match your closing date. It might not. For a rental, it’s often the point when the unit is rent-ready and actively offered for rent. For a business building, it can be the date you can operate, not the date you signed a purchase contract.

Save proof: permits, contractor sign-off, dated photos, listings, and the first lease.

Build A Solid Basis File Before You Depreciate

Depreciation only works as well as your basis math. Basis usually starts with what you paid, plus costs tied to acquiring the property, plus later capital work. A clean basis file also makes future decisions easier, like refinancing, partial sales, or insurance claims.

For purchases, owners often keep one folder that includes the closing statement, loan documents, any appraisal, and a simple land/building allocation worksheet. If you don’t have an appraisal that splits land and improvements, two common approaches are:

• Assessor ratio method: use the local tax assessment values for land and improvements, then apply the same ratio to your purchase price.
• Appraiser split method: use an appraisal that lists separate land and improvement values.

Also watch the closing statement lines. Some items are current expenses. Some get capitalized into basis. Title work, recording fees, and certain legal fees often belong in the capital bucket. Items tied to financing, like loan points, can follow different rules than property basis. If you keep the HUD-1 or closing disclosure and label each line item once, you won’t have to reverse-engineer it later.

Recovery Periods Owners See Most Often

Real property depreciation usually comes down to picking the right recovery period and then using straight-line depreciation with the mid-month convention.

Residential rental buildings generally sit on a 27.5-year recovery period. Nonresidential real property generally sits on 39 years. Rental specifics are summarized by the IRS in IRS Publication 527 (Residential Rental Property).

Mixed-Use Buildings Can Split The Math

A property can be part residential and part commercial. In that case, owners often allocate basis across the uses (often by square footage), then depreciate each slice under the matching recovery period. Your method should be consistent and backed by your files.

Not Everything Around A Building Has The Same Life

Some spending lands outside the main building bucket. Land improvements like certain paving or fencing can have different lives. Inside, some assets can be personal property rather than structural components. That’s where cost segregation comes in. If you use a study, keep the report and the backup evidence.

Repairs Versus Improvements

The most common owner mistake is treating a big improvement like a current-year repair. The IRS’ Tangible Property Final Regulations explain how to separate deductible repairs from capital improvements, plus elections and safe harbors that can simplify the call.

A practical rule of thumb: repairs keep the property operating as it is, while improvements add value, extend life, or adapt the property to a new use. Improvements are capitalized and then depreciated.

For buildings, the rules also treat major systems as their own buckets, like HVAC, plumbing, electrical, fire protection, elevators, and the building structure. Replacing a small part of a system can look like a repair. Replacing a large portion can push it into improvement territory.

Common Building Costs And How They’re Usually Treated

Real estate bookkeeping gets easier when you sort spending into a few repeatable buckets. Use this table to triage invoices, then match the final treatment to your facts and records.

Cost Or Property Type	Typical Treatment	Detail That Often Decides It
Land purchase value	Not depreciable	Allocation backed by appraisal or assessor split
Residential rental building	Depreciate over 27.5 years	Placed-in-service month affects first-year amount
Nonresidential real property	Depreciate over 39 years	Use based on tenant mix and operations
Full roof replacement	Often capitalized and depreciated	Scope and system impact drive repair vs improvement
Turnover paint and patch	Often deductible maintenance	Remodel context can change classification
Parking lot, fencing, exterior lighting	Often depreciated as land improvement	May have a shorter life than the building
Appliances in a rental unit	Often depreciated as personal property	Attachment to structure can change classification
Tenant build-out paid by owner	Often capitalized	Lease terms and ownership drive treatment

How Depreciation Changes The Yearly Tax Picture

Depreciation is a non-cash deduction. You can have steady cash flow and still report lower taxable income because depreciation sits on the return as an expense. That’s normal.

Two realities keep planning honest:

• Depreciation reduces adjusted basis over time, which matters when you sell.
• When you dispose of the property, part of the past depreciation can be treated as recapture under the tax rules.

So, treat depreciation as timing. It shifts when you pay tax, and it changes the shape of the numbers from year to year.

What Happens When You Sell

Depreciation doesn’t vanish when you dispose of the property. Over the years, depreciation reduces your adjusted basis. When you sell, that lower basis can increase the gain you report. Tax law can also treat some of the past depreciation as depreciation recapture, which can be taxed differently than long-term capital gain.

That sounds scary, yet it’s predictable when your records are clean. Keep the original allocation, your depreciation schedules, and a log of capital projects. When you sell, those three items make it far easier to compute gain, track recapture, and defend the numbers if questions come up.

Fast Checks Before You Claim Building Depreciation

These checks catch the issues that show up most often in real files. If you can answer each line with a document, your depreciation story is usually solid.

Check	What To See In Your File	What To Do If It’s Missing
Land carved out	Workpaper that splits land and building	Create allocation using appraisal or assessor ratios
Use qualifies	Lease, rent roll, or business use documentation	Depreciate only the qualifying portion
Placed-in-service date	Permit, listing, lease, or dated completion proof	Collect proof and set the date consistently
Right recovery period	Residential rental vs nonresidential classification notes	Reclassify and rebuild the schedule
Repairs vs improvements coded	Invoices grouped by project and system	Recode spending using the building system approach
Depreciation schedule saved	Year-by-year schedule tied to the tax return	Rebuild the schedule and store it with tax files

Short Answers To Common Owner Scenarios

Converted Personal Home

If a personal home becomes a rental, depreciation usually starts when it’s rent-ready and offered for rent. Basis and allocation rules can shift at conversion, so document the conversion date, the property condition, and your land/building split.

Inherited Or Gifted Property

Basis rules can differ for inherited and gifted property, and depreciation follows that basis once the property is used for rental or business purposes. Keep the paperwork that backs your starting basis since it’s the anchor for every future year.

Tenant Improvements

Lease terms decide a lot. If the landlord owns the improvement, it’s often capitalized and depreciated by the landlord. If the tenant owns it during the lease, the treatment can sit on the tenant’s side. Your lease file should match your tax treatment.

A Clean Way To Think About The Whole Topic

When owners ask “can I depreciate this building,” they’re usually asking four smaller questions:

• Is the use business or income-producing?
• What part of my cost belongs to the building after land is split out?
• When was the building placed in service?
• Is this spending a repair or an improvement?

Answer those four, keep the documents, and your depreciation deductions tend to stay boring. Boring is good here.
