Renovation budgets: why a contingency line matters

Projects rarely cost exactly what the first sketch suggested. A budget with room in it is calmer to live with.

4.1Budget lines to include

LineExamples
MaterialsCabinets, flooring, tile, fixtures, paint
LaborTradespeople, installers, general contractor if used
Soft costsPermits, design help, disposal, temporary storage
Living costsEating out while a kitchen is closed, a temporary bathroom
ContingencyA set percentage held back for the unexpected

4.2What a contingency is

A contingency is money you set aside, separate from the main budget, for problems found once work begins, such as rot behind a wall or an out-of-date wiring panel. How much to hold back depends on the age of the home and the type of work. Ask a licensed professional what is reasonable for yours.

4.3Changes cost more midstream

Changing your mind after work starts usually costs more than deciding earlier. Make the big choices, like layouts and major fixtures, before work begins, and ask how changes are priced.

4.4Track as you go

Keep one simple list of what you have spent against each line. If one line runs high, you can see which other line to trim, or whether to pause and decide.
