Updated September 5, 2026. Quick answer: For condos, Oklahoma’s statute leaves the collection method to the bylaws and defaults general decisions to a majority vote of unit owners; for subdivision HOAs, the statute simply hands the association a levy-and-lien power with no vote requirement at all, so the real approval rule comes from each community’s own declaration or bylaws.
Key statute: Okla. Stat. tit. 60, §§ 501-530 (Unit Ownership Estate Act, Oklahoma condominium law); Okla. Stat. tit. 60, §§ 851-858 (Real Estate Development Act, governing subdivision HOAs)
How Oklahoma lets an association approve it
For condominiums, bylaws must state the “manner of collecting from the unit owners for the payment of the common expenses” (60 O.S. § 520(d)), and general meeting decisions require that “a majority of unit owners… is required to adopt decisions” (60 O.S. § 520(b)); special assessments aren’t separately addressed. For subdivision HOAs, 60 O.S. § 852(C) gives “the owners association… the power to enforce any obligation in connection with membership in the owners association by means of a levy or assessment which may become a lien,” with no statutory vote requirement whatsoever; approval terms come entirely from the recorded owners-association instrument.
The notice you’re owed
Neither act sets a per-assessment notice requirement. The only notice-related protection is a one-time onboarding disclosure under the Real Estate Development Act: “No lien may be placed or mortgage foreclosed unless the homeowner was informed in writing upon joining the owners association of the existence and content of the owners association restrictions and rules, and of the potential for financial liability to the individual owner by joining said owners association” (60 O.S. § 852(C)).
Paying it: plan, interest, and late fees
Statute is silent on both acts. We read the full bylaws-contents section (60 O.S. § 520) and the full books/records section (60 O.S. § 521) for condos and the full Real Estate Development Act (§§ 851-858), and found no statutory right to pay a special assessment in installments and no interest-rate cap or late-fee rule for delinquent assessments; these terms are left to the declaration/bylaws.
For condos, “[a]ll sums assessed by the council of unit owners for the share of the common expenses chargeable to any unit which sums remain unpaid shall constitute a lien on such unit,” foreclosable “in like manner as an action for foreclosure of a mortgage upon real property” (60 O.S. § 524(a)-(b)). For subdivision HOAs, an unpaid levy/assessment “may become a lien… which said lien may be foreclosed in any manner provided by law for the foreclosure of mortgages or deeds of trust,” and “the prevailing party shall be entitled to recover reasonable attorney’s fees” (60 O.S. § 852(C)).
Does Oklahoma require a reserve study?
No. Having read the full Unit Ownership Estate Act (60 O.S. §§ 501-530) and the full Real Estate Development Act (60 O.S. §§ 851-858), neither imposes any reserve-study, reserve-fund, or capital-funding-plan requirement.
Honest gaps
Oklahoma’s condo statute predates the modern Uniform Condominium Act and doesn’t separately address special versus regular assessments, so approval/notice/payment terms for a special assessment specifically are governed by each association’s own declaration, not the statute. The official oklegislature.gov/oksenate.gov PDF of Title 60 could not be read directly, so the current codified section text was read through the Oklahoma State Courts Network (oscn.net), which mirrors the official statutes; we did not review every other cross-referenced provision of Title 60 outside the two chapters cited.

General information drawn from each state’s own statutes as read at its official legislature or code-publisher site (or a verbatim codified mirror where noted), not legal advice. Special-assessment law is state law, and every association’s own declaration and bylaws add rules on top of the statutory floor described here. We are not a law firm and this is not legal advice.
