Are you grandfathered in when the HOA changes the rules?
Reviewed by the OurHOA team · Updated July 2026
Written approval you relied on is the strong version. Eleven years of nobody complaining is the weak one. What actually protects a nonconforming feature.
What grandfathering actually means
The word gets used loosely, so start with the precise version. A feature is grandfathered, or in legal shorthand a nonconforming use, when it complied with the rules in force at the time it was built or installed and a later rule change would have prohibited it. Grandfathering is not a general right to keep anything that has been sitting there a while. It is a narrow argument that the new restriction does not reach backward to your shed, your fence, or your rental. Two things have to be true for it to work: the feature was legitimate when it happened, and the new restriction either does not say it applies retroactively or cannot lawfully be made to.
Written approval is the strong version of the argument
Say the architectural committee approved your detached garage in writing in 2016, you built it to the approved plans, and the board adopted a stricter outbuilding standard in 2024. You are on solid ground, and the reasoning courts use is estoppel: you asked the party with authority to say yes, that party said yes, and you spent real money relying on the answer. A later board generally cannot undo the reliance a prior board created just because it would have decided differently. This is also why the approval letter matters far more than anyone believes at the time. Verbal approval from a board member at a block party is worth very little, and boards turn over a lot faster than fences fall down.
A covenant amendment and a board rule are not the same thing
Boards blur these constantly and homeowners should not. Recorded covenants are amended by an owner vote at whatever threshold the declaration sets, often two thirds or three quarters. Operating rules are adopted by the board itself, under authority the declaration grants, usually with a notice period and a comment window. Rules generally cannot contradict the covenants, and they cannot manufacture a restriction the declaration never authorized. California writes this into statute: under Civil Code section 4350, an operating rule is enforceable only if it is in writing, within the board's authority, not in conflict with law or the governing documents, adopted in good faith and in substantial compliance with the required procedure, and reasonable. So if a board is telling you to remove something under a rule it passed at a meeting, the first question is not whether you are grandfathered. It is whether the declaration ever gave the board power to regulate that subject at all.
Some states answer the question by statute
Rental restrictions are the clearest case of a legislature deciding grandfathering rather than leaving it to courts. Florida Statutes section 720.306(1)(h) provides that an amendment adopted after July 1, 2021 that prohibits or regulates rental agreements applies only to an owner who acquires title after the amendment takes effect, or who consents to it. The exceptions are real and narrow the protection: amendments regulating rentals of six months or less, and amendments prohibiting rentals more than three times in a calendar year, apply to everybody. So a Florida owner who bought in 2018 and rents on twelve-month leases keeps that right through a 2023 rental ban, while the same owner running weekend stays does not. Other states have their own versions on their own subjects, and plenty have none at all, which is why an honest answer to this question always begins with which state you are in.
When the association simply never said anything
There is a second, weaker argument that people also call grandfathering: the fence has been there eleven years and nobody ever complained. That is not grandfathering. It is one of three related defenses - waiver, laches, and estoppel. Waiver is the claim that the association enforced the covenant so laxly for so long that it gave up the right to enforce it now. Laches is the claim that the association delayed unreasonably and you were prejudiced by the delay, meaning you spent or did something you would not have if they had spoken up. Estoppel is the claim that the association's words or its silence told you the rule would not be enforced and you relied on that. There is no magic number of years for any of them, and none is a right you hold in advance. They are defenses you raise after the association has already come after you, usually with lawyers in the room, which is a far worse position than holding the approval letter.
How grandfathered status gets lost
The most common way people lose a nonconforming feature is by improving it. Rebuild the rotted fence and it is a new fence subject to today's standard, not the one from 2009. Expand the shed by half and you may be told to bring the whole structure into compliance. Replace a grandfathered roof and the current color and material rules generally apply to the replacement. The other way it disappears is a change in ownership, and that depends entirely on how the exemption was created. A grandfather clause written into the recorded covenants usually runs with the land and survives a sale. An informal understanding between one homeowner and one board that never made it onto paper usually does not, which is how buyers end up with a violation notice in month two. If you are buying and something on the property looks like it would not be approved today, ask for the approval paperwork before closing, not after.
Making the argument and keeping the record
Start by finding the paper. Pull the approval application, the committee's written response, dated photos, the county permit if one was issued, and the version of the covenants or rules that was in effect the year you built. Then compare the old language to the current language and be honest with yourself about whether the feature actually complied back then, because the argument collapses if it did not. Write to the board rather than arguing at a meeting, attach the documents, and ask them to confirm in writing that the feature is recognized as nonconforming. If you are on the board and changing a rule going forward, the cleanest move is to write the exemption into the amendment itself with an explicit cutoff date and a sentence about what happens on replacement, because that removes the ambiguity these fights are made of. A board that keeps architectural approvals, dated rule versions, and the minutes that adopted them in one searchable place can settle a grandfathering question in ten minutes instead of ten increasingly unpleasant emails, and holding that record for self-managed boards is a large part of what OurHOA is for. None of this is legal advice, and how much weight courts give grandfathering, waiver, and laches varies considerably by state and by what your declaration says, so talk to your association attorney before either side digs in.
