In Washington, commercial maintenance obligations are primarily governed by the terms of the written lease agreement and general contract law principles. Unlike the residential sector, which is bound by the non-waivable Implied Warranty of Habitability under the RLTA (RCW 59.18.060), there is no statutory implied warranty of habitability for commercial properties in Washington.

In the commercial sector, this warranty does not exist.

Maintenance responsibilities in Washington commercial real estate are dictated by the written lease agreement. The allocation of repair duties, including structures like Triple Net (NNN) leases and Common Area Maintenance (CAM) charges, is determined by the contractual agreement between the landlord and tenant.

1. Single-Tenant Properties: Absolute NNN

If a commercial tenant rents an entire freestanding building in Washington (e.g., a standalone retail store, a warehouse in Kent, or an industrial facility in Everett), the lease is almost always structured as an absolute Triple Net (NNN) Lease.

Under a pure NNN lease, the tenant assumes total responsibility for the entire property:

• Daily Operations: Landscaping, janitorial services, parking lot maintenance, and (given Washington's climate) significant rain gutter and drainage upkeep.
• Systems Maintenance: HVAC servicing, plumbing maintenance, electrical panel inspections.
• Major Structural Repairs: If the roof fails or the HVAC unit catastrophically dies during a Pacific Northwest winter storm, the tenant pays for the replacement.

2. Multi-Tenant Buildings and CAM Charges

In multi-tenant commercial buildings (like the office towers in downtown Seattle or strip malls across the Puget Sound region), the landlord typically retains physical control over the common areas—but recovers 100% of the costs from tenants via Common Area Maintenance (CAM) Charges.

The Annual CAM Reconciliation

1. The Estimate: At the start of the year, the landlord estimates total building operating costs (e.g., $200,000). A tenant occupying 15% of the building pays $30,000 annually ($2,500/month) in addition to base rent.
2. The Reconciliation: At year's end, the landlord audits actual expenses. If the persistent rain required more drainage repairs and the actual bills were $240,000, the tenant receives an invoice for their share of the $40,000 shortfall ($6,000). If bills were only $180,000, the tenant gets a $3,000 credit.

3. Condition at Surrender (Dilapidations)

Washington commercial leases routinely require the tenant to return the premises in "good condition and repair, ordinary wear and tear excepted."

When a lease expires, the landlord will perform a rigorous walk-through inspection comparing the property's condition against the baseline established at lease commencement. Any tenant-caused damage (cracked flooring, damaged drywall, broken fixtures) will be itemized and charged to the tenant—potentially deducted from their security deposit or invoiced separately.
