Landscaping and Irrigation
Land is not depreciable. Landscaping that would be destroyed with a related depreciable asset is often class 00.3 land-improvement property as reproduced in Publication 946 Appendix B. The dealership matrix uses that replacement test. Trentadue classified vineyard irrigation as a land improvement and trellises as personal property. Educational information, not tax advice.

Key takeaways
- Publication 946 Appendix B, reproducing Rev. Proc. 87-56, lists asset class 00.3 land improvements — sidewalks, roads, drainage, fences, landscaping, and shrubbery — with a 15-year GDS recovery, and excludes buildings and structural components.
- Land itself cannot be depreciated.
- The auto-dealership matrix treats landscaping that would not be replaced with a depreciable asset as land, and landscaping that would be destroyed with a related depreciable asset as class 00.3.
- Trentadue: underground drip irrigation and a well were land improvements; trellises were not inherently permanent.
- Metro National treated lawn sprinkler heads as part of an inherently permanent structure on those facts.
Planting grass on raw land does not, by itself, create a depreciable asset. Treas. Reg. §1.48-1(c) excludes land and improvements such as buildings or other inherently permanent structures from tangible personal property. Buildings, swimming pools, paved parking areas, wharves, docks, bridges, and fences are listed as not tangible personal property. A building is a roofed enclosure used for shelter, housing, or working, office, parking, display, or sales space. Structural components are parts of that building. Landscaping sits outside the building. The usual depreciable home, if any, is a land improvement.
IRS Publication 946 (2025), Appendix B, reproduces Rev. Proc. 87-56 class 00.3. Rev. Rul. 2003-81 quotes that class: improvements directly to or added to land, whether section 1245 or section 1250, provided they are depreciable, with examples including sidewalks, roads, canals, drainage facilities, sewers other than municipal sewers, wharves and docks, bridges, fences, landscaping, shrubbery, and radio and television transmitting towers. Class 00.3 excludes land improvements explicitly included in any other class, and buildings and structural components as defined in section 1.48-1(e). GDS recovery is 15 years; ADS is 20 years. Land remains non-depreciable.
Publication 5653’s auto-dealership matrix applies a replacement test. Landscaping that would not be replaced when a related depreciable asset is replaced is land. Landscaping that would be destroyed with a related depreciable asset is class 00.3. The residential and pharmaceutical matrices mention irrigation systems with fencing and site work. Those rows are examiner guidance. Activity classes can override 00.3 when they specifically include related land improvements, which is the parking-lot-at-the-plant example in Rev. Rul. 2003-81.
Trentadue v. Commissioner, 128 T.C. 91 (2007), applied Whiteco’s six permanence factors — a court test, not a statute — to vineyard assets. Trellises were not permanent land improvements. Drip irrigation was a land improvement mainly because substantial piping was buried and hard to remove. The well was also a land improvement. Metro National treated lawn sprinkler heads as part of an inherently permanent structure, not as personal property. AmeriSouth allowed irrigation outlets and timers among a small set of items. Courts have split on irrigation hardware depending on how permanently it is installed.
Building fire sprinklers are not landscaping; they are listed structural components. Do not place a wet-pipe grid in class 00.3 because lawn heads were litigated in Metro National. Scott Paper electrical allocation does not classify sod. Costing sitework requires allocating land preparation among land, building, and depreciable land improvements, which Publication 5653 Chapter 5 tells examiners to watch, with before-and-after photographs.
Land versus class 00.3
General grading to create a level lot is typically non-depreciable land. Plantings that would be ripped out when a parking lot is reconstructed are the dealership-matrix 00.3 fact pattern. A specimen tree far from any depreciable improvement may remain land. The test is whether the landscaping would be destroyed when the related depreciable asset is replaced, not whether plants are pretty.
Irrigation as a land improvement
Buried mains, valves, and heads that serve site plantings are often class 00.3. Trentadue’s buried drip system is the modern regular Tax Court example. Metro National’s lawn heads were inherently permanent on those facts. Controllers and quick-couplers that AmeriSouth allowed are examples, not a national irrigation class. Photograph burial depth and attachment.
Whiteco on items in the ground
The six questions ask whether the property can be moved, whether it was designed to stay, expected affixation, difficulty of removal, damage on removal, and manner of affixation. Rev. Rul. 2003-54 used the same factors to treat canopy footings as inherently permanent land improvements while the canopy structure was personal property. Irrigation laterals often look like the footings side of that split.
Activity-class overrides
Rev. Rul. 2003-81: a parking lot related to a steam-production plant fell in the utility activity class because that class specifically includes related land improvements; a headquarters lot 100 miles away stayed in 00.3. Theme-park class 80.0 includes park land improvements. Petroleum-marketing land improvements can fall in class 57.1. Read the activity class before assuming every shrub is 00.3.
Documentation
Site plans, planting schedules, irrigation as-builts, and before-and-after photographs of land preparation belong in the file. Publication 5653 Chapter 4 expects a legal analysis and a cost reconciliation that does not depreciate land. Super Intelligence extraction is proposed.
