How Much to Budget for Home Maintenance

The 1% rule says save 1% of your home’s value a year for repairs. See why it’s only a heuristic and build a budget from roof, boiler and appliance lifespans.

7 min read · Updated

A common starting point is to set aside 1% of your home’s value each year for maintenance and repairs, and financial educators put the range at 1% to 3%, with older homes at the high end. Those are rules of thumb, not standards, so a better budget adds up what your actual roof, boiler, water heater and appliances will cost to replace and divides it by the years they have left.

This guide shows both methods, explains why the percentage rule can mislead in New York City, and works through an example for a house and for a co-op or condo apartment.

The rules of thumb, and what they miss

The 1% rule

The Consumer Financial Protection Bureau’s homebuying worksheet includes a line for home maintenance and says a common rule of thumb is 1% of your target home price, divided by 12 for a monthly amount. Cooperative Extension finance educators say most experts recommend 1% to 3% of the home’s value, and that the older the home, the more maintenance and repairs it will need. They also point out that spending varies from year to year, and unspent money can carry forward.

The $1 per square foot rule

You will also see “$1 per square foot per year.” It is a popular heuristic with no official source. It ignores the home’s age, materials and local labor costs, so treat it only as a sanity check.

Why percentage rules can mislead in NYC

A home’s price includes the land under it, and land prices vary far more from place to place than the cost of a roof or a boiler. A roof on a house worth twice as much does not cost twice as much to replace. In a high-priced market like New York City, 1% of value can overstate what a well-kept house needs in a normal year, and still understate it in the year the boiler fails. A component budget fixes both problems.

Build a component budget

A sinking fund means saving small amounts now for a cost you know is coming. For each big item, you need three numbers: what it costs to replace, how old it is, and how long that type of item usually lasts.

Worked example: a two-family rowhouse

Every dollar figure below is a hypothetical input for illustration. Replace it with quotes for your own home. Say you own a brick two-family rowhouse worth $1,100,000. The 1% rule says $11,000 a year, and the 3% end of the range says $33,000.

Flat roof (modified bitumen)$15,00012208$1,875
Boiler$12,000254015$800

The component plan comes in well under 1% of value. That doesn’t mean the 1% figure is wrong for you. The component plan has no line for surprises: a sewer line, a facade crack, a sidewalk violation or a leak that rots a joist. Many owners add a contingency on top, or keep a separate emergency fund (see the homeowner emergency fund calculator). NYC house owners also carry city-specific costs, such as sidewalk repairs and water and sewer bills, which belong in your operating budget rather than your repair fund.

Budgeting in a co-op or condo

Apartment owners budget differently. The building pays to replace the roof, boiler, elevator and facade out of your monthly maintenance or common charges and its reserve fund. Your own budget has two parts instead.

1. What you fix inside your unit

Who fixes what inside the apartment is set by the building’s documents, not by a single law. In a co-op, read the proprietary lease and house rules. In a condo, read the declaration and bylaws. Owners are usually on the hook for their own appliances, fixtures, finishes and any improvements they or a previous owner made. Pipes inside the walls and risers are a common gray area, so look it up before something leaks.

2. Special assessments and maintenance increases

When reserves fall short, the board can raise maintenance or charge a special assessment. In NYC, big triggers include facade work under Local Law 11, emissions upgrades under Local Law 97, roofs and boilers. You can usually see these coming:

  • Read the last two or three years of audited financial statements. Note the reserve fund balance and whether it is growing.
  • Ask the managing agent about planned capital projects and any assessment already approved.
  • Check board minutes, if the building shares them, for facade, roof or boiler discussions.
  • Look up the building on Roofy’s building lookup for open DOB violations and facade filings.

Your condo or co-op insurance can help with one kind of assessment. Loss assessment coverage helps you pay an assessment the association charges to help pay for covered losses to common areas. Some condo owner policies include it in the basic policy, so ask your agent or insurer. Because it is tied to covered losses, don’t count on it for assessments that pay for routine repairs or upgrades. More in special assessments.

Worked example: a two-bedroom co-op

Again, every number here is hypothetical. Say your kitchen appliances are six years old and the apartment was last painted four years ago. Your in-unit sinking fund might be: refrigerator $1,800 over 5 years left ($360 a year), dishwasher $900 over 3 years left ($300 a year), and interior paint $3,000 over 8 years left ($375 a year), plus $600 a year for small repairs. That totals $1,635 a year, or about $136 a month.

Now suppose the board has announced a facade project and your share of the special assessment is $6,000, due in 24 months. Saving $250 a month covers it. Your full apartment budget is about $386 a month while the assessment is pending, and about $136 after. Compare that with 1% of a $700,000 apartment value ($7,000 a year, or $583 a month). The percentage rule would double count the building systems your maintenance already pays for.

Keep the fund working

  • Keep it in a separate high-yield savings account so it isn’t spent on other things.
  • Update the list every year. Replace an item’s age with zero after you replace it.
  • Spend from the fund on schedule. Cheap upkeep, like boiler service and roof inspections, extends expensive lifespans.
  • Follow a seasonal routine with the home maintenance checklist.
  • Fold the result into your full cost of owning. See the true monthly cost of owning a home in NYC.
