Land Improvements and the 15 Year Class

Between the land, which cannot be depreciated, and the building, which is depreciated slowly, sits a third category: land improvements. These are often overlooked and can be meaningful, especially on properties with significant site work.

What they are

Land improvements are generally improvements to land, other than buildings, that have a determinable life and are depreciable. The tax classification for many such items is 15 years. They are generally depreciated using a declining balance method, which is more accelerated than the straight line method used for buildings.

Common examples

• Paved parking lots and driveways.
• Sidewalks and curbs.
• Fencing and retaining walls.
• Landscaping and irrigation systems.
• Site lighting.
• Certain drainage and utility work outside the building.
• Signage in some cases.
• Pools and outdoor recreational features in some cases.

The precise treatment of each depends on its nature and use.

Why they matter

Land improvements are frequently a substantial part of the cost of commercial properties, and some residential properties, especially those with parking areas, landscaping, or amenities. Because they generally have a shorter life than the building, they can produce faster deductions. They may also be eligible for bonus depreciation, subject to current rules. See How Bonus Depreciation and Cost Segregation Interact.

Distinguishing from land

Some site work is treated as part of the land and is not depreciable, for example, work that is inherent in preparing the land, such as grading in some circumstances. The line between land preparation that adds to land basis and depreciable land improvements is a matter of facts and law. This is an area where a careful study earns its cost. See Land Versus Building Allocation and Why It Comes First.

Distinguishing from the building

Some items close to the building, such as certain sidewalks, entrances, or utility connections, may be treated as part of the building or as separate improvements. Case law and guidance discuss such distinctions. A study analyzes them.

New construction and site work

For new construction, the contractor's invoices often separate site work. If that is so, the study can allocate costs directly. See Timing for New Construction and Renovations.

Purchased property

For a purchased property, a study would estimate the cost of land improvements using cost references and reconcile to the price paid. The estimate's quality matters.

Replacement

When you replace paving or landscaping, the treatment of the old item's remaining basis and the new item's cost are separate questions. See Partial Dispositions, Replaced Components, and Studies.

Recapture

Land improvements are real property. On sale, depreciation on them in excess of straight line, if any, can be recaptured as ordinary income, and the remaining depreciation is generally treated as unrecaptured gain taxed at a maximum rate. See Unrecaptured Section 1250 Gain in Plain Terms. The exact treatment depends on the rules in effect, so check.

Property types with more land improvements

Properties with large parking areas, extensive landscaping, or amenities may have more to analyze. Examples include suburban commercial properties, apartment communities, and self-storage facilities. See Commercial Properties: The Study Decision and Multifamily Properties: The Study Decision.

What to ask a provider

Ask whether the study will identify and value land improvements separately, how the provider distinguishes them from land, and what documents are needed.

Illustrative cases in words

An apartment community with a large surface parking lot, sidewalks, exterior lighting, a pool, and landscaping may have a meaningful land improvements category. A single-family rental with a driveway and a fence may have a small one. A retail center may have significant paving and signage. A warehouse may have a large paved area and loading aprons. In each case, the share depends on the site, and the study estimates it.

Questions to raise with a provider

Ask how the provider will treat site preparation costs, such as grading and excavation. Ask how utility connections outside the building will be handled. Ask whether landscaping is included and how mature plantings are treated. Ask whether the provider distinguishes between items that are part of the land and items that are depreciable improvements. Ask how replaced items on the site will be tracked.

Lifespan and replacement

Paving and landscaping wear out and are replaced. When they are replaced, the old item's basis, if identified, may be disposed of, and the new item's cost is capitalized in a new asset. Keep a record so that your schedule remains accurate.

A note on maintenance versus replacement

Routine maintenance of paving, such as sealing or patching, is generally a repair that may be deducted. Full replacement is generally capitalized. Ask your preparer where the line falls for your project.

Coordination with the local jurisdiction

Some site work is required by local codes and is part of the cost of development. Municipal fees and required off-site improvements can have their own treatment, sometimes added to land basis. Ask your preparer how these were treated when you bought or built.

Records to keep

Keep paving contracts, landscaping invoices, fencing receipts, and lighting installation documents, with dates. If you bought the property with these features in place, keep the closing documents and any survey or site plan that shows them. Photographs of the site at acquisition help a later reviewer see what existed.
