Every shape is a parcel. Shaded ones have a permit of the chosen type on file. Pick a type to see where it clusters. No addresses are shown.
Permits on file from city and county records. Some permits are not confirmed final, so these are permits, not finished jobs. Hatched parcels are in Algona, Federal Way, Pacific, where we do not have permit records yet. That is not the same as no work, and they are left out of the percentages.
Most homes here have already replaced each system at least once, so this is an estimate of the yearly volume, not a count.
Estimates from public records and typical lifespans, for the 10,112 homes with a year built on record. The roof estimate assumes composition shingle, the most common roof here. Not an inspection.
1,069 finaled permits on file, all-time — city/county records, not tied to any one address.
Ranked by permits on file. Business names come from public permit records — not a recommendation or vetting by SeattleHomework.
Right now it is probably in your head, or a shoebox of receipts. When did we last service the AC? Is the roof still under warranty? Who redid the water heater? SeattleHomework keeps every repair and upgrade in one place, so you always know what has been done and what is coming up. And when you sell, that history becomes proof for the next owner, the way a full service record sells a car.
Every repair, upgrade, and service, with the date and who did it. No more guessing or digging through old email.
See when the roof, AC, or water heater is getting close, before it fails.
A documented home reassures buyers and can help it sell faster.
