Washington Commercial Leases ## Commercial vs. Residential Leases Commercial leases are negotiated contracts between sophisticated parties — businesses and commercial landlords. Unlike residential leases, commercial leases are NOT governed by RCW 59.18 (the Residential Landlord-Tenant Act). There is no implied warranty of habitability, no mandatory security deposit return timeline, no just cause eviction requirement, and far fewer consumer protections.

Landlord perspective: Bears all expense risk; if taxes or maintenance costs rise, the landlord absorbs it. ### 2. Net Lease (and Variations) The tenant pays base rent PLUS some or all operating expenses. The key variations: | Type | Tenant Pays | |---|---| | Single Net (N) | Base rent + property taxes | | Double Net (NN) | Base rent + taxes + insurance | | Triple Net (NNN) | Base rent + taxes + insurance + maintenance/CAM charges | Triple net (NNN) is the most common structure for commercial retail and industrial properties. The tenant pays for nearly everything. Base rent is typically lower to compensate. Real-world exam trap: "Net" does not always mean the same thing — always identify whether it is N, NN, or NNN. Triple net = all three: taxes + insurance + CAM (common area maintenance).…
