What the law actually requires

Oregon regulates condos and planned communities under two parallel statutes: ORS 100.175 governs condominiums and ORS 94.595 covers planned communities. Both require the association to maintain a reserve account and to commission a reserve study analyzing the maintenance, repair, and replacement of common elements over a 30-year horizon.

Oregon's framework requires that the reserve study be updated when there are 'material changes' to the components or replacement costs — there is no fixed cycle, but the 'material change' standard effectively requires a 3-5 year refresh for most associations as components age and material costs shift.

Reserve account funds in Oregon must be held in a separate account from operating funds and can only be used for the major maintenance, repair, restoration, or replacement of common elements identified in the reserve study. Diverting reserve funds to operating purposes is a statutory violation and a recognized fiduciary breach under Oregon HOA case law.

How Apex Reserve Studio handles Oregon

Apex Reserve Studio's Oregon compliance jurisdiction enforces the 30-year projection requirement and produces ORS 100.175 / 94.595 disclosure language that distinguishes the protected reserve account from operating funds. The condo and planned-community PDF builders handle the slight format differences between the two statutory schemes.

Frequently asked questions — Oregon

How often does an Oregon HOA need a reserve study?

Oregon does not mandate a fixed cycle, but ORS 100.175 / 94.595 require the study to be updated when there are 'material changes' to components or replacement costs. Most Oregon associations refresh their study every 3-5 years to remain defensible.

What's the difference between Oregon condos and planned communities?

Oregon regulates condominiums under ORS 100 and planned communities under ORS 94. The reserve requirements are nearly identical but technically separate statutes — Apex's compliance jurisdiction handles both with slight PDF format differences.

Can Oregon reserve funds be used for operating expenses?

No. ORS 100.175 / 94.595 require reserve funds to be held in a separate account and used only for the major maintenance, repair, restoration, or replacement of common elements. Diversion to operating purposes is a statutory violation.

What is Oregon's reserve study projection horizon?

30 years. Oregon's statutes explicitly require a 30-year analysis of common-element components, longer than Hawaii's 20-year minimum and matching the NRSS-recommended best practice.
