Book Your Free InspectionThe Lettered Streets, A through G Streets between downtown Bellingham and the Sehome area, form one of the oldest continuously occupied residential blocks in the city. Homes here date from the late 1800s through the early 1900s. They are dense, close-built, and occupied by a mix of longtime residents and student renters in proximity to Maritime Heritage Park and the Whatcom Museum complex.
This combination, old construction, high rental density, and proximity to the drainage network connecting to the waterfront, makes the Lettered Streets one of the most consistent Norway rat call areas in Bellingham.
The Lettered Streets Rodent Profile
Norway rats in the Lettered Streets arrive via the same mechanism as in Columbia: the drainage corridor connecting the waterfront to the residential edge of the neighborhood. G Street, which runs along the higher bluff edge, sees less direct pressure than A, B, and C Streets, which are lower and closer to the drainage network near the Bellingham waterfront.
The student rental population in the Lettered Streets adds a second dynamic. High tenant turnover means pest problems often go unreported between tenants. A gap under the kitchen range or behind the bathroom sink that has existed since the building was constructed in 1902 may have never been sealed, tenants trap mice and move out, the next tenants inherit the same entry points. House mice are common in the interior wall voids of Lettered Streets rental units alongside the Norway rat crawlspace pressure from below.
Entry Points in Lettered Streets Homes
Late 1800s Bellingham construction creates a specific entry point profile:
Foundation mortar joints: Brick or stone foundations in the oldest Lettered Streets homes have mortar joints that have deteriorated over 120-plus years. Small voids between brick courses, especially near grade level, are Norway rat entry points that are invisible without a flashlight and a close inspection.
Original wood sill plates: Pre-1900 sill plates in the Lettered Streets are often made from old-growth Douglas fir, which resists decay well, but the connection to the foundation has settled and in many cases separated. A gap of a quarter inch runs the length of the sill plate in the worst cases.
Under-floor entry via plumbing: Original cast-iron drain stacks in Lettered Streets homes create floor-level gaps at every fixture location, the toilet drain, the bathroom sink drain, the kitchen drain, where the pipe passes through the subfloor. These gaps are routinely found unsealed.
What Rodent Control Looks Like in the Lettered Streets
Given the density of the neighborhood and the age of the homes, we recommend calling in September before the October pressure season begins. Pre-season inspection and exclusion in A, B, and C Street homes, the most Norway rat-affected blocks, is the most effective timing.
Inspection: Full crawlspace and perimeter inspection, with specific attention to mortar joint condition, sill plate gaps, and plumbing penetrations. Foundation mortar joints require a flashlight and a pick in the oldest buildings.
Exclusion: Mortar joint repointing is outside our scope (that’s a masonry contractor job), but sealing the accessible gaps with hardware cloth and metal flashing is within it. We distinguish between structural masonry repair and pest exclusion sealing in our written estimate so there are no surprises.
Frequently Asked Questions
Who is responsible for rodent control in a Lettered Streets rental property?
Under Washington State RCW 59.18.060, the landlord is responsible for maintaining the property in a habitable condition, which includes freedom from pest infestation. When a tenant reports a mouse or rat problem in writing, the landlord has 24 hours to respond for emergency conditions affecting health and safety. For property owners in the Lettered Streets managing student rentals, between-tenant exclusion work, with a written inspection report documenting completed sealing, establishes both the practical solution and the legal compliance record under Washington State tenant law.
Is the mouse problem in my Lettered Streets apartment a landlord issue or my responsibility?
Under Washington State law, if the infestation was present before you moved in, or if it results from the building’s condition (entry points in the structure that predate your tenancy), it is the landlord’s responsibility. If the infestation resulted from conditions you created, leaving food unsealed, creating harborage, the analysis is more nuanced. Submit your report in writing (email is sufficient) and request written confirmation of the planned remediation timeline. Under RCW 59.18.060, you have specific rights if the landlord fails to respond within the required time.
