Can an HOA stop you from installing hardwood floors?
Reviewed by the OurHOA team · Updated July 2026
Why condos regulate hard surface flooring, what IIC and STC ratings mean, and how to get an install approved without a noise fight.
It depends almost entirely on what is under you
In a single-family community, nobody cares what you put on your floors. The covenants govern the exterior, and the inside of the house is yours. In a condominium or any stacked or attached building, flooring is one of the most heavily regulated things you can touch, because the floor of your unit is the ceiling of somebody else's bedroom. Pulling carpet and putting down oak, tile, or luxury vinyl plank removes the single best sound absorber in the building, and the person below you hears it the first morning you walk to the coffee maker.
What the documents usually say
Three patterns show up. Some CC&Rs flatly prohibit hard surface flooring above the ground floor. More commonly, the documents permit it but route it through architectural review, so you need written approval before installation and the board can attach conditions. The third pattern is a performance standard: hard surface is fine as long as the finished assembly hits a stated sound rating, usually verified by the underlayment manufacturer's test report or, in stricter communities, a field test after installation. Ground floor units and units over a garage or unoccupied space are often exempt outright, since there is no one underneath to protect.
IIC and STC, decoded
Two acronyms run this whole conversation. STC, the Sound Transmission Class, measures airborne noise like voices and television. IIC, the Impact Insulation Class, measures footfall and dropped objects, which is the one that actually causes flooring disputes. Higher numbers are better. The International Building Code requires floor and ceiling assemblies separating dwelling units to hit at least 50 for both STC and IIC when tested in a lab, or 45 when tested in the field, and plenty of associations write a higher number than that into their rules. The catch worth understanding before you buy anything: those ratings belong to the whole assembly, not to the underlayment roll. The same pad that tests at 60 over an eight-inch concrete slab can land well below that over a wood joist floor, so a spec sheet number means nothing until you match it to your building's construction.
The rug rule
Even where hard surface is allowed, many condos and co-ops require area rugs covering a set share of the floor, often 80 percent of everything except kitchens and bathrooms. Owners tend to read that as decorating advice, and it is not. It is an enforceable rule, and courts have backed it up. In Ryland Mews Homeowners Association v. Munoz, a 2015 California appellate decision, an owner replaced his carpet with hardwood without approval, partly to help his wife's severe dust allergy, and the neighbor below started hearing everything. The court upheld an injunction requiring him to cover much of the floor with rugs while the case proceeded. Worth noting that a medical need for hard flooring is not automatically a losing argument, but it belongs in a written reasonable accommodation request to the board before installation, not as a defense after the fact.
Floors that were already there when you bought
This is the situation that catches people, because you did not install anything. If the previous owner put hardwood in without approval, the violation generally runs with the unit, and you can inherit the enforcement letter. Before closing, ask the association in writing whether the flooring was approved, and get the answer in the estoppel or resale package rather than from the seller. Genuinely grandfathered installations, meaning ones approved under the rules in effect at the time, usually stay put when the rules later tighten. Unapproved ones are a different story, and even an approved floor is not immune if the noise rises to a nuisance under the governing documents.
How to get it approved without a fight
Submit before you order materials, not after the installer is on site. A packet that gets approved usually has the product and underlayment spec sheets, the lab test report showing the IIC and STC of the assembly over your building's floor type, the installer's name and insurance, and the proposed schedule so the board can check it against construction hour rules. Offer to add rugs in the high-traffic paths even if the rules do not require them, because it costs you little and removes the objection before it is raised. Then keep everything: the approval letter, the test report, and the photos of the underlayment going down before the flooring covered it. Owners who can produce that packet years later almost never lose a noise complaint, and boards that keep approvals and architectural records where the next owner can actually find them, which is the sort of thing OurHOA is built to handle, stop relitigating floors every time a unit changes hands.
