Maple Valley Home Remodeling

61 percent of Maple Valley homes went up between 1990 and 2009

The Census Bureau's 2020 to 2024 survey puts Maple Valley at 9,633 housing units; 5,858 were built in the 1990s or 2000s, including 3,312 in the 2000s alone. The median year built is 2001, and just 35 homes predate 1940. Houses from those years are now 17 to 36 years old, the age when original roofs, water heaters, furnaces and builder-grade kitchens and baths come up for replacement, often within a few years of each other.

Maple Valley rates winter wind, snow and ice as a high-probability hazard

The city's section of the King County hazard mitigation plan says Maple Valley is subject to severe winds, rain, snow and ice, and that past storms brought road closures, downed trees, power outages and some structural damage. The Cedar River runs outside city limits, and the plan records no flood losses in the city to date. The city sits on the edge of the urban growth boundary next to rural forest, which it rates as a low probability wildfire risk with moderate impact. For a remodel, that points to roofs and siding rated for wind, trees cleared from the roofline, and a plan for power outages.

Maple Valley protects trees 12 inches across and larger

Under the tree ordinance in effect since March 22, 2023, a significant tree is any healthy evergreen or deciduous tree at least 12 inches in diameter at four and a half feet above grade, not counting alder or cottonwood. A landmark tree is 24 inches or more. Cutting a significant tree normally takes a Clearing and Grading Permit. Existing single-family lots of two acres or less are exempt, unless the trees sit in a recorded Tree Retention Plan or Tree Protection Area. On a house lot, a hazard tree or any tree within one and a half tree lengths of an existing or permitted building can also come down without that permit.

Usually not on a normal house lot. Maple Valley exempts existing single-family lots of two acres or less, unless the tree is in a recorded Tree Retention Plan or Tree Protection Area.

How do I apply for a building permit in Maple Valley?

Everything is submitted through the city's OpenGov portal; paper and walk-in submittals are not accepted.

First confirm your parcel is inside city limits.

Who issues electrical permits in Maple Valley?

L&I, the state labor department, issues them. Maple Valley handles building, plumbing and mechanical permits through OpenGov, but electrical permits and inspections for addresses in the city come from L&I, which you can reach at 360-902-5269. Even an express rooftop solar permit from the city still needs a separate L&I electrical permit.
