A condominium act is the state law that makes it legally possible to divide one building into separately owned units while keeping the roof, lobby, elevators, and grounds under shared ownership, and it sets the ground rules for how the community is created, governed, funded, and sold. About 14 states have adopted the Uniform Condominium Act, a model statute drafted by the Uniform Law Commission, and the remaining states have their own versions that mostly follow the same shape. If you own a unit, sit on a board, or are thinking about buying, this is the law behind almost every right and obligation attached to the property.
How a Condominium Legally Comes Into Existence
A condominium doesn’t exist until a developer records a document called the declaration with the local land records office. The declaration is the founding instrument. It names the condominium, describes the land, defines how many units the developer can build, and assigns each unit its share of the common areas, voting power, and expense obligations. Every adopting state requires these core elements, and many add their own disclosures on top.
Along with the declaration, the developer records plats and plans that work as a three-dimensional map of the property. These drawings fix the exact boundary of each unit by referencing the interior surfaces of walls, floors, and ceilings, so every cubic foot of the building is classified as either private space or shared property. Without this precision, there is no reliable way to tell where your unit ends and the common structure begins.
Recording these documents does two things. It puts future buyers and lenders on notice that the property carries specific legal restrictions, and it turns each unit into an independently taxable, sellable parcel of real estate. If the paperwork isn’t properly recorded, the whole structure can fail, leaving owners with unclear title and lenders unwilling to finance.
What You Actually Own
Condominium property splits into three categories. Your unit is the private interior space you own outright. Common elements are everything shared by all owners: structural frame, roof, lobbies, elevators, hallways, grounds. Limited common elements are shared-property areas reserved for specific units, like a balcony reachable only from your apartment or a storage locker assigned to your deed.
When the declaration is filed, each unit receives a percentage interest in the common elements. That percentage usually tracks the unit’s size relative to the building’s total livable area, though some declarations use other formulas. A large three-bedroom might carry a 2.5 percent interest while a studio carries 0.8 percent. The same percentage controls three things at once: your share of common expenses, your voting weight in association decisions, and your ownership stake in the shared property.
Here is what catches buyers off guard. That allocation is essentially permanent. Under most condominium acts, changing any unit’s common-element interest, voting share, or expense allocation requires unanimous consent from every owner in the building. A simple majority won’t do it, and neither will a supermajority. The narrow exceptions involve structural changes to the condominium itself, such as a developer adding units to an expandable project or the association relocating boundaries between adjoining units.
The association maintains the common elements out of the collective budget. When a limited common element needs repair, the act typically allows the association to charge the cost to the units that actually benefit from it, so a ground-floor owner isn’t subsidizing a penthouse terrace they’ll never set foot on.
Your Rights and Duties as a Unit Owner
Owning a condominium gives you fee-simple title to your interior space, the same form of ownership you’d have with a house. You can renovate, decorate, sell, rent, or mortgage the unit, subject to whatever restrictions the governing documents impose. You also have the right to use the common areas for their intended purposes.
Those rights come with obligations. You are responsible for maintaining everything inside your unit’s boundaries, including plumbing fixtures, appliances, and interior finishes. If you neglect that maintenance and water damage spreads to a neighbor’s unit, you are on the hook for the resulting harm. The line between your maintenance responsibility and the association’s follows the boundaries drawn in the declaration, which is why reading the plats and plans actually matters.
You are also bound by the bylaws and any rules the board adopts. These commonly cover noise, pets, rental restrictions, and modifications to exterior-facing areas like balconies and windows. Violating a rule can bring fines, and the specific amounts vary by state. Some states cap fines per violation, others cap the total that can accumulate from a single ongoing infraction. The key protection across most acts is that fines must be applied uniformly. A board cannot selectively enforce a pet rule against one owner while ignoring the same violation next door.
Notice Before New Rules Take Effect
Boards cannot create rules on a whim. Most condominium acts require some form of notice before a new rule takes effect, giving owners a chance to review and comment. The specific notice period varies by state, but the principle is consistent: owners are entitled to know about proposed rule changes before they are binding. Emergency rules addressing immediate safety or financial threats are an exception in many states, though those emergency measures typically expire after a set period unless formally adopted through the normal process.
The Association and the Board
Every condominium act requires a unit owners’ association to manage the shared property and enforce the governing documents. It is usually organized as a nonprofit corporation. All unit owners are automatic members with no opt-out, and each owner’s voting power corresponds to the percentage interest assigned to their unit in the declaration.
An elected board of directors runs day-to-day operations: budgets, vendors, maintenance, rule enforcement. Board members owe a fiduciary duty to the association, meaning they must act in the community’s interest rather than their own, use reasonable care in making decisions, and avoid conflicts of interest. This is the same general standard that applies to directors of any nonprofit corporation, and it is the basis for holding board members accountable when they mismanage funds or engage in self-dealing.
Owners can remove board members, though the process depends on the governing documents and state law. Most acts allow removal with or without cause unless the bylaws specifically require cause. The removal must happen at a properly noticed meeting called for that purpose. If your board is underperforming, don’t wait for the next annual election. Check your bylaws for the removal procedure and the number of votes needed to call a special meeting.
The association must hold at least one annual meeting where elections occur and the budget is presented. Notice requirements vary by state but typically run from one to four weeks before the meeting date. For any vote to count, a quorum must be present, meaning enough owners show up in person or by proxy to constitute a valid assembly. The specific threshold is set in the bylaws. If you’ve ever sat through a meeting that couldn’t proceed because not enough people showed up, that is the quorum rule at work.
Most association business must be conducted in open meetings any owner can attend. Boards can hold closed executive sessions, but only for sensitive matters such as pending litigation, personnel issues, contract negotiations, collection actions against delinquent owners, or consultation with the association’s attorney. The board must state the purpose of the closed session on the record, and any formal action taken must be recorded in the minutes of the next open meeting. A board that routinely conducts ordinary business behind closed doors is likely violating the act.
Assessments, Liens, and What Happens If You Don’t Pay
The association funds its operations through assessments levied against every unit based on that unit’s allocated percentage of common expenses. Regular assessments are typically billed monthly and cover insurance, maintenance, utilities, landscaping, and reserves for future capital projects. When an unexpected expense hits, the board can impose a special assessment to cover the shortfall. That authority generally rests with the board, though some declarations require owner approval above a dollar threshold.
Failing to pay is serious. The act gives the association an automatic lien against the delinquent unit for the unpaid amount plus interest and reasonable attorney fees. No court filing is needed to create the lien. It attaches by operation of law the moment an assessment goes unpaid.
Priority is where this gets consequential. Under the model act and most state versions, the association’s assessment lien is senior to nearly all other claims against the unit, with three main exceptions: liens recorded before the declaration was filed, first mortgages recorded before the delinquency, and government tax liens. Most versions of the act give the association a limited super-priority over even a first mortgage, typically covering six months of unpaid assessments. That lets the association recover at least several months of delinquent payments even if the unit is foreclosed by the bank, protecting the community from absorbing the full loss.
If the debt stays unpaid, the association can foreclose on the unit to satisfy the lien. It is the nuclear option, but it exists because the alternative is worse. If owners can simply refuse to pay, the remaining owners get stuck covering the shortfall. Late fees and interest rates are regulated by state law to prevent abuse, with caps that vary by jurisdiction.
Buyer Disclosures and the Right to Cancel
Condominium acts build in significant protections for buyers, and this is an area where people routinely leave money on the table by not understanding their rights.
Public Offering Statements for New Units
Before selling any unit in a new condominium, the developer must give each buyer a public offering statement. This disclosure goes well beyond a standard listing. It must include a description of the condominium and its amenities, the construction timeline, copies of the declaration and bylaws, a projected budget for the association’s first year broken out by expense category, a description of any warranties, disclosure of pending litigation, and information about any rights the developer has reserved to expand or modify the project. It must also disclose the projected monthly assessment for each unit type, whether any reserve funding is included in the budget, and any services the developer is providing that the association will eventually need to fund on its own. Developers who fail to deliver a compliant offering statement face potential liability, including the buyer’s right to cancel.
Resale Certificates for Existing Units
When an existing unit changes hands, the buyer is entitled to a resale certificate from the association. This document discloses current assessment amounts, any unpaid balances, the association’s financial statements and budget, reserve fund balances, pending litigation, insurance coverage, and any known violations on the unit. The association must produce the certificate within a set timeframe after the seller requests it, typically between 10 and 14 days depending on the state. Preparation fees generally run from $250 to $400.
Read the resale certificate before closing. It is the single best window into whether the association is financially healthy or heading toward a special assessment. A community with minimal reserves and an aging roof is a community where you will be writing a large check within a few years of moving in.
The Statutory Right to Cancel
Most condominium acts give buyers a statutory right to cancel the purchase within a set period after receiving the disclosure documents. The window exists because condominium purchases carry obligations (assessments, rules, shared governance) that don’t apply to a conventional home purchase. The cancellation period and conditions vary by state, but the right typically cannot be waived in the purchase contract.
Developer Turnover to Owner Control
When a condominium is first created, the developer controls the association’s board. That makes practical sense early on, since few units have been sold and the developer is still building and marketing. But the act imposes a phased transition that gradually shifts power to the residents, tied to the percentage of units sold to non-developer buyers. Full owner control kicks in no later than 60 days after three-quarters of the units have been sold, or two years after the developer stops offering units for sale, whichever comes first. A developer can also hand over control earlier by recording an instrument to that effect.
Turnover is one of the most consequential moments in a condominium’s life, and it is where associations most often get blindsided. The new owner-controlled board should immediately request all association records, contracts, financial accounts, and insurance policies from the developer. Many states require the developer to fund an independent audit covering the entire period from the association’s incorporation through the turnover date. That audit is the board’s best tool for identifying whether the developer underfunded reserves, deferred maintenance, or entered into sweetheart contracts with affiliated companies. Moving quickly matters because warranty claims and legal actions against the developer are subject to statutes of limitations that run regardless of whether the new board has discovered the problem.
Insurance: What the Association Covers and What You Cover
Condominium acts require the association to maintain property and liability insurance covering the common elements and the building’s structure, to the extent that coverage is reasonably available in the market. The association’s policy typically covers the building’s exterior, structural components, and common areas. Individual owners are responsible for insuring their personal property, interior improvements, and personal liability.
Two details trip people up. The association’s policy must generally include a waiver of the insurer’s right to pursue claims against individual unit owners. Without that waiver, the association’s insurer could pay a claim for building damage and then turn around and sue the owner whose unit was the source of the problem. Second, if the association fails to carry the required insurance, most acts require the board to disclose that gap to all owners. Your own coverage decisions depend on what the association’s policy does and doesn’t cover, so you need to know.
Changing or Ending the Condominium
The declaration can be amended, but it is deliberately difficult. Most acts require approval from owners holding at least 67 percent of the association’s total voting power, and the declaration itself can set a higher threshold. Some changes require more: altering any unit’s allocated interest in common elements, voting power, or expense share requires unanimous consent. Amendments must be recorded in the land records to take effect, the same as the original declaration.
Termination dissolves the condominium regime and converts the property back into a single parcel, usually for a bulk sale. The threshold is high. Most acts require agreement from owners holding at least 80 percent of the association’s voting power. The declaration can raise that threshold but generally cannot lower it below 80 percent for residential condominiums. Some older condominiums created before a state adopted the model act may require unanimous consent for termination unless the community opts into the newer statute.
When a condominium is terminated, sale proceeds and any remaining association assets are distributed among the owners in proportion to their percentage interest in the common elements. Outstanding debts and liens against the association or individual units must be satisfied from the proceeds before distributions are made. Minority owners who voted against termination still receive their proportional share, but they cannot block the sale once the required supermajority has approved it.
What the Act Doesn’t Resolve
Condominium acts provide the structural legal framework, but they don’t settle every issue you’ll run into as an owner. Rental restrictions, age restrictions, and short-term leasing policies are governed by the declaration and bylaws rather than the act itself, though the act establishes the procedures for adopting and enforcing those policies. Disputes between neighbors over noise, odors, or behavior usually play out through the association’s internal enforcement process before reaching a courtroom. And while the act gives associations significant power, it does not make them immune from fair housing laws, state consumer protection statutes, or federal regulations that override conflicting provisions in the governing documents.
If you are buying into a condominium, the most useful thing you can do is read the declaration, the bylaws, and the most recent financial statements before closing. The condominium act gives you the right to receive these documents. Use that right, because the problems that cost owners the most money are almost always visible in the paperwork before they show up in a special assessment notice.
