A backyard cottage or basement unit you can rent out or house family in - Seattle's fastest-growing way to add space without moving.
Getting an EV? A licensed electrician runs a dedicated circuit - and sometimes a panel upgrade - to charge it safely at home.
Older homes often can't handle modern loads - EVs, heat pumps, hot tubs - until the panel is upgraded first.
Instead of digging up your yard, trenchless repair fixes a broken sewer line from the inside - faster and less disruptive.
Swapping a gas furnace or old AC for a heat pump cuts energy bills and often qualifies for utility rebates.
Bolting the foundation and bracing cripple walls so an older Seattle home can survive an earthquake.

An ADU (accessory dwelling unit) is any secondary living space on a property, including one attached to or inside the main house. A DADU (detached ADU) is a separate structure - a backyard cottage - which is what most people picture when they say "ADU" in Seattle.
Yes. Replacing a furnace or AC system with a heat pump requires a mechanical/trade permit from SDCI, filed by a licensed HVAC contractor.
Based on recent local permits, panel upgrades average a few thousand dollars, varying with amperage and whether the service line also needs upgrading.
It's not universally mandatory for single-family homes, but it's strongly recommended for older homes with cripple walls or unbolted foundations, and required for certain unreinforced masonry buildings under city policy.
It's the estimated cost of the construction project itself (what you'd pay a contractor) - not the permit fee. Seattle calculates the actual permit fee separately, from a city fee schedule based on that project value. A $15,000 remodel might carry a permit fee of roughly $1,000, not $15,000.
A contractor with a long, verifiable permit history has a real, city-recorded track record - not just marketing claims. It won't tell you if they're pleasant to work with, so pair it with reviews, license status, and insurance - but permit volume is a strong first filter that can't be faked or bought.
Yes - neighborhood pages show recent permit activity, common project types, and active contractors, useful context for a CMA or buyer conversation about a property's improvement history or ADU potential.
