Should your local government require commercial landlords to disclose building infrastructure and fee data?

Seattle lawmakers are set to vote on October 20, 2026, on a commercial lease transparency ordinance that would require property owners to disclose key infrastructure data. The policy aims to protect small businesses from hidden costs and unpredictable fees.

Why it matters

Unpredictable operating fees and infrastructure defects disproportionately affect immigrant- and minority-owned enterprises. By mandating disclosure, the city seeks to level the playing field for local business owners operating in commercial zones.

The ordinance mandates that landlords disclose triple-net operating fees and infrastructure conditions. Coverage includes most commercial spaces, though residential, office, research, and medical facilities remain exempt from these rules.

The details

Proposed by the Office of Economic Development, the legislation requires landlords to provide signed lease copies, Certificates of Occupancy, and annual inspection access for operating invoices. Enforcement does not involve city citations, instead relying on tenants to initiate civil lawsuits for financial damages.

Market Landscape

This legislation marks a significant expansion of commercial real estate regulation by shifting the burden of information onto property owners. It positions the city as a more active regulator in commercial lease disputes compared to historical standards that favored private contract terms.

Small business owners may experience reduced financial uncertainty regarding operating costs and infrastructure maintenance after the policy takes effect. Tenants will gain the legal right to audit annual invoices, potentially saving money on unexpected fee spikes.

The takeaway

Business owners in commercial corridors should begin documenting current lease terms and infrastructure concerns to prepare for potential disclosure requirements. This move highlights a broader trend toward mandating higher transparency standards in private business contracts.
