Washington State Commercial Rent Increase Rules
A critical distinction for Washington landlords managing mixed portfolios: House Bill 1217's landmark rent stabilization caps (7% + CPI, or 10%) apply exclusively to residential tenancies. Commercial properties in Washington state are completely exempt from these restrictions.
Commercial rent increases are governed entirely by the "Rent Escalation" clauses negotiated into the multi-year lease agreement.
1. Fixed Base Rent Increases (Stepped Rent)
The most predictable escalation method. The lease explicitly states the exact base rent for every year of the term:
These increases are automatically enforceable on the exact anniversary dates stated in the lease, with no additional statutory notice required.
2. Indexed Escalations (CPI Clause)
Many Washington commercial landlords, particularly in the Seattle-Tacoma metro, tie annual rent increases to the Consumer Price Index (CPI) for the Seattle-Tacoma-Bellevue metropolitan area.
- The rent automatically increases by the same percentage the CPI rose over the previous 12 months.
- Caps and Floors: Leases routinely include "collars" (e.g., the CPI increase, but no less than 2% and no more than 5%) to protect both parties from extreme economic volatility.
3. Percentage Rent (Retail)
Common in Washington's retail sector (malls, shopping centers, downtown Seattle retail strips):
- The tenant pays a lower fixed "Base Rent."
- Additionally, they pay a percentage of their gross sales revenue once those sales exceed a negotiated threshold (the "natural breakpoint").
4. Holdover Premiums
If a commercial tenant in Washington remains in the building after their lease has expired without signing a renewal, most leases impose a harsh "holdover premium"—often 150% to 200% of the last month's rent—for every month the tenant illegally occupies the space. Washington courts consistently enforce these provisions as legitimate liquidated damages.
