NOIs

NOIs is an acronym that can refer to several terms across different fields. The two most common meanings are Notice of Intent, used in regulatory and permitting contexts, and Net Operating Income, a key metric in real estate and finance. The term’s meaning depends on jurisdiction and industry.

Notice of Intent (NOI) in regulatory contexts denotes a formal document filed to begin a permit process or to indicate compliance intent. In environmental regulation, an NOI is often used to authorize coverage under a stormwater or wastewater permit, or to initiate actions under air and water quality programs. The NOI outlines project details, location, expected discharges, and the permit applicant. In other settings, an NOI may signal intent to participate in regulatory proceedings or to meet specific reporting requirements. The document is typically followed by further applications, plans, or compliance steps and may carry deadlines or conditions.

Net Operating Income (NOI) is a financial measure of a property’s profitability from ongoing operations. It equals gross operating income minus operating expenses, with operating expenses typically including property management, maintenance, utilities, insurance, and property taxes, but excluding financing costs, depreciation, and amortization. Investors use NOI to assess performance and to estimate value via capitalization rates (value equals NOI divided by the cap rate). NOI is also used in budgeting, underwriting, and comparative analysis of real estate assets, including commercial and multifamily properties.

Other uses of the acronym NOIs appear in specialized contexts within certain organizations or industries; meanings may vary by field. When encountering NOIs, it is important to identify the relevant domain and jurisdiction to determine the correct interpretation.
