How to use this Commercial Lease Agreement in Washington

Start with the exact legal names of both entities and decide on a personal guaranty. Enter the rentable area of the premises and the building — that ratio becomes the tenant's share of taxes, insurance and CAM in a modified gross or NNN lease — then set the term, rent commencement, renewal options and escalation. Choose the maintenance split and insurance limits deliberately: they are the clauses that cost money later.

Answer the state-disclosure questions, review the cure periods (pre-filled with Washington's statutory figures where they exist) and decide whether to waive the landlord's lien for the tenant's equipment lender. Both parties sign with name and title; attach the floor plan, work letter, guaranty and rules.

Frequently asked questions

Is a commercial security deposit regulated in Washington?

No — Washington has no statute on commercial security deposits (residential rules do not apply), so the amount, use and return are whatever the lease says; this lease sets a 30-day return with an itemized statement.

How much notice must I give a commercial tenant before eviction in Washington?

Washington requires 3 days' written notice before an eviction action for nonpayment and 10 days for other breaches (RCW 59.12.030); the lease may set a different contractual cure period, and this lease pre-fills it with the statutory figure.

Is there a tax on commercial rent in Washington?

No — commercial rent is not subject to sales or occupancy tax in Washington.

Does a commercial lease need a notary or witnesses in Washington?

No — a written lease signed by both parties is valid for any term; a notary is needed only if you record the lease or a memorandum of lease (RCW 64.04.010).

What is the difference between a gross and a triple-net (NNN) lease?

In a gross lease the base rent covers taxes, insurance and common-area maintenance, so the landlord bears cost increases. In a triple-net lease the tenant pays its pro-rata share of those three items on top of base rent, reconciled annually against actual costs. Modified gross sits between: the tenant pays only increases over a base year. This lease drafts all three, and in Washington the landlord also keeps a statutory lien on the tenant's goods (RCW 60.72.010) unless waived.
