Common property is everything in a condominium, townhome, or planned community that sits outside the walls of an individual unit and belongs to all owners collectively — the roof over your head, the lobby you walk through, the pool, the parking lot, the pipes running between floors. You hold an undivided interest in it alongside every other owner, which means you cannot claim a specific square foot as your own, and the community association manages it on everyone’s behalf using the dues you pay.
What Counts as Common Property
Common property falls into three broad categories. Structural components come first: the foundation, roof, exterior walls, and load-bearing framing that hold the building together. Shared infrastructure comes next, including main electrical systems, centralized plumbing lines, elevator shafts, and fire suppression equipment. Then there are the amenities most people picture when they hear the term: fitness centers, pools, parking structures, and landscaped grounds.
The definition reaches past what you can see. Utility easements, drainage systems, and shared access roads are common elements too, even though residents rarely think about them until something fails. The Uniform Common Interest Ownership Act, a model law adopted in some form by a number of states, is the framework behind most of these definitions. Under the UCIOA, common elements in a condominium or cooperative include everything in the development that is not part of an individual unit; in a planned community, they include any real estate the association owns or leases other than the units themselves.
Limited Common Elements
Not everything shared is shared equally. Limited common elements are portions of the common property reserved for the exclusive use of one or a few units. Your private balcony, assigned parking space, patio, or basement storage locker are the familiar examples. The association still owns these spaces; you simply have the sole right to use them.
Where unit ownership ends matters here. The UCIOA draws unit boundaries at the interior finished surfaces of walls, floors, and ceilings. Everything past those surfaces — structural framing, the exterior face of a balcony, the concrete slab under your patio — belongs to the common elements. You cannot make structural changes to your own balcony without association approval, and the same principle explains why you cannot repaint your front door or alter other exterior surfaces on a whim.
Who Maintains What
Your governing documents spell out the split, and the split varies widely from one community to another. In general, the association handles structural integrity — keeping a balcony’s concrete and railing sound, for instance — while you handle day-to-day upkeep like cleaning and clearing debris. Some declarations charge the cost of repairs to a limited common element only to the owners who use it, rather than spreading the expense across the whole community. Read your declaration carefully before you assume anything.
When Shared Spaces Cause Damage
Water damage is the most common flashpoint. If a pipe serving only your unit fails because the association neglected maintenance, the association generally bears responsibility for both the repair and the resulting damage inside your unit — drywall, flooring, cabinets, mold remediation. The reverse applies too. Let your balcony drain clog and send water into the unit below, and you can face liability for failing to maintain the limited common element assigned to you. The question in any dispute is where the problem started and whether the responsible party met their maintenance duty.
What You Pay For Common Property
Every owner pays regular assessments, usually monthly or quarterly, into a fund the association uses to maintain the common property. These dues cover landscaping, cleaning, utilities for shared spaces, insurance premiums on the master policy, and management fees. The board of directors sets the budget and decides how the money is allocated.
Reserve Funds
Beyond operating costs, a well-run association keeps a reserve fund for major repairs and replacements: a new roof, repaving the parking lot, replacing an aging elevator. The industry benchmark treats a reserve at 70% or more of projected future costs as adequately funded. Associations below that line face a higher risk of surprise charges when something expensive breaks. A growing number of states now require periodic reserve studies, which estimate the remaining useful life and replacement cost of major common elements so the association can set aside enough each year to avoid a single catastrophic bill.
Special Assessments
When reserves fall short, or an emergency hits that no one budgeted for, the board can levy a special assessment. This is a one-time charge on top of regular dues, and the amount can range from a few hundred dollars per unit for a modest project to well into five figures for a major structural repair after years of deferred maintenance. Owners who don’t pay risk having the association file a lien against their unit, and in most states the association can foreclose on that lien. Unpaid assessments can ultimately cost you your home.
What the Board Owes You
Board members managing these funds owe a fiduciary duty to the community. That duty breaks into two parts: a duty of care, meaning they must make reasonably informed decisions and exercise ordinary diligence, and a duty of loyalty, meaning they must act in the community’s interest rather than their own. Chronically underfunding reserves, ignoring deteriorating common elements, or diverting maintenance money elsewhere can form the basis of a breach of fiduciary duty claim that owners can bring.
Insurance on Common Property
Most state condominium statutes require the association to carry a master policy covering common elements. That policy pays for structural damage from covered events such as fire, storms, and water intrusion. It does not cover your personal belongings, interior upgrades inside your unit, or your personal liability.
That gap is where your individual condo policy, commonly called HO-6 coverage, comes in. An HO-6 covers your personal property, interior improvements, and liability within your unit. It also usually includes a small amount of loss assessment coverage, which pays your share when the master policy’s limits or deductible leave a shortfall. Default loss assessment coverage is often low, around $1,000 in a standard policy, so a large uninsured loss at the building level could leave you owing much more. Increasing that coverage is usually inexpensive, and worth considering in older buildings.
The association also carries liability insurance for injuries that occur on common property. If a guest slips on an icy walkway or trips over a broken step, the association can be held liable when the injury resulted from negligent maintenance. Associations that ignore known hazards or delay repairs after notice face the greatest exposure.
Rules You Have to Follow
Living in a common interest community means following the governing documents: typically a Declaration of Covenants, Conditions, and Restrictions (CC&Rs), bylaws, and supplemental rules adopted by the board. These control how you use shared areas, covering noise, pets, pool hours, guest access, and much more. You cannot store personal items in shared hallways, hang unapproved signs from your balcony, or treat common space as an extension of your unit.
Aesthetic rules are a frequent source of friction. Many communities prohibit hanging laundry on balconies, installing visible satellite dishes, or painting a front door an unapproved color. Agree with them or not, they are enforceable once recorded in the governing documents.
How Rules Get Enforced
Enforcement usually follows a graduated path. The typical sequence starts with a written violation notice, escalates to fines for continued non-compliance, and can lead to suspension of amenity privileges or legal action. Fine amounts and procedures vary by community and state law. Most governing documents require the board to give the owner notice and a chance to be heard before imposing penalties.
Changing Anything That Touches Common Property
If you want to modify something that touches common property — adding a structure to your patio, installing a new exterior light, changing your front landscaping — you need written approval before starting. Most communities route these requests through an architectural review committee that evaluates whether the proposal complies with the governing documents and fits the community’s aesthetic standards. Submit thorough plans; incomplete applications are the most common reason for delay or denial. A denial should come with a written explanation, and many communities let you modify the proposal and resubmit.
Resolving Disputes
Disagreements over maintenance, rule enforcement, or assessment levels are inevitable. Many states require or strongly encourage alternative dispute resolution before anyone files suit. Mediation brings in a neutral third party who helps both sides work toward a voluntary agreement; nobody is forced into a particular outcome. Arbitration is more formal, with an arbitrator hearing evidence and issuing a binding decision.
Mediation tends to be faster and cheaper, and it is better suited to a community where people still have to live next to each other. Arbitration fits disputes where the parties are too far apart to negotiate or one side is clearly not acting in good faith. Check your CC&Rs; many include a mandatory dispute resolution clause that requires mediation or arbitration before litigation. Even without one, going outside court first is almost always the smarter move. Suing your own association is expensive, slow, and damages the community long after the legal issues are settled.
How Common Property Affects Buying and Selling
The condition and financial health of common property directly affect your ability to buy or sell. Before a sale closes, the association provides a resale disclosure package (sometimes called a resale certificate) that includes current financial statements, reserve balance, any pending or planned special assessments, and information about ongoing litigation. Review it closely. An underfunded reserve or a looming special assessment can add thousands of dollars in costs that are not reflected in the purchase price.
Lenders look at common property too. Fannie Mae will not purchase mortgages on units in projects that need critical repairs, defined as conditions that significantly affect safety, structural integrity, or habitability. That includes material deficiencies likely to cause system failure within a year, active water intrusion or mold, advanced physical deterioration, and unfunded repairs exceeding $10,000 per unit that should be completed within the next twelve months. Projects where the association is involved in litigation related to structural safety or habitability are also ineligible.1Fannie Mae. Ineligible Projects If a building fails these standards, conventional financing dries up, values drop, and selling becomes very difficult.
Fannie Mae also looks at financial health. Association budgets that allocate less than 10% of total assessment income to reserves raise red flags in loan review. A building with chronically deferred maintenance and thin reserves is a property future buyers may struggle to finance, which affects your investment whether you plan to sell next year or a decade from now.
