Tacoma has about 222,800 residents (American Community Survey 2024 5-year). The median home was built in 1967, about 43% of homes predate 1960 and about 27% predate 1940. About 56% of occupied homes are owner-occupied, with a median value of $479,600.
Seattle-Tacoma International Airport records a normal 39.34 inches of precipitation a year, with November (6.31 inches), December (5.72) and January (5.78) the wettest months and July the driest at 0.60 inches (NOAA, 1991-2020). The 2001 Nisqually earthquake, magnitude 6.8, was centered about 52 kilometers deep beneath Anderson Island; the PNSN notes that Tacoma had less damage than Seattle despite being closer, which it attributes to differences in the ground beneath each city.

Foundation Repair in Tacoma: Questions
How do I know if my Tacoma house is bolted to its foundation?
Look in the crawl space where the wood sill sits on the concrete: anchor bolts with nuts and washers every few feet are a good sign. Older homes may have few or none. A provider can check and quote bolting; Fixr and HomeGuide put foundation bolting at $1,000 to $5,000.
When is the best time to check for foundation and drainage problems in Tacoma?
During or just after the winter rains, when problems show. November through January bring about 17.8 inches of rain together at Sea-Tac in a normal year (NOAA 1991-2020). Note where water collects and take photos, then schedule repairs for the drier months if the work involves digging.
