Cost and timing

Half of 25,747 city permits list an amount in this range. Permit amounts are often lower than what you pay.

How to read this range
Contractors write a job value on the permit form, and the city uses it to set the permit fee. It is not the contract price, and it is often lower than what you pay. A quarter of the permits list less than this range, and a quarter list more. Use it to see if a quote is in the normal range.
Rebates
Seattle's Clean Heat Program: $2,000 off for most homes that switch from oil heat to a Mitsubishi Electric heat pump. Households earning 81% to 150% of the area median income get $4,000 more, $6,000 in all. The install must be finished by May 30, 2027, by one of the program's participating contractors.
