How Much Should a Building Budget for Maintenance? The 2–4% Rule

How Much Should You Budget for Building Maintenance?

How Much Should a Building Budget for Maintenance?

A widely cited guideline from a 1990 U.S. National Research Council report is to budget 2–4% of a building's current replacement value each year for maintenance and repair. As our own rule of thumb, older buildings tend to need the high end. It is a planning guideline, not a price: real quotes and your own past spending should refine it.

Replacement value is what it would cost to rebuild the building today, not its market price. Your property insurance policy often states a figure close to it.

How to Apply It

Find the current replacement value.
Pick a point in the 2–4% range. As our own rule of thumb, use the low end for a newer building in good condition and the high end for an older or heavily used one.
Compare with what you spent in each of the last three years.
Split the result into preventive contracts, repairs and a reserve.

Our budget calculator does the arithmetic.

What the Guideline Leaves Out

Utilities, cleaning and security
Backlogs of deferred work, which need separate funding
Major upgrades and changes of use

Lease Check

Under a triple-net lease the tenant may pay for much of this; under a gross lease the landlord usually does. Read who pays for roof and HVAC replacement before budgeting.

Refine It With Quotes

Ask two or three contractors to price your actual systems and compare the quotes. Local rates vary a lot, so we do not publish a national price per square foot.
