Montana has no comprehensive HOA act. Most homeowners assume that means HOAs have free rein — it does not. In Montana, your CC&Rs are a binding contract that courts enforce strictly, and the state still provides meaningful protections for retroactive rule changes and political signs.
If you just received an HOA fine in Montana, the first question most homeowners ask is: what does Montana law say my HOA has to do? The answer is less than Florida, California, or Colorado — but that does not mean you are without defenses.
Unlike states with comprehensive HOA acts, Montana relies heavily on contract law. Your CC&Rs, bylaws, and rules are the contract between you and the association. When your HOA deviates from that contract — wrong notice period, wrong fine amount, skipped hearing — that is a breach you can challenge in court. No statute required.
On top of that contract defense, Montana does have two specific statutory protections homeowners regularly overlook. This guide covers exactly what state-law protections do exist (MCA §70-17-901, §70-1-522), and how to use breach-of-contract defenses when your HOA fines you in Montana.
Montana has no comprehensive HOA statute for planned communities. This is not an oversight — the Montana legislature has consistently declined to pass a blanket HOA regulation law. As a result, when you look for the “Montana HOA Act,” you will not find one.
What does govern Montana HOAs:
There is no Montana statute requiring written notice before a fine. No statute requiring a hearing. No statutory fine cap. Your CC&Rs fill that gap — and that is where the contract defense lives.
This sounds like bad news for homeowners. But here is the insight most Montana homeowners miss: because your CC&Rs are a binding contract, every procedural requirement in them is enforceable. The HOA drafted those documents. If the CC&Rs say “14 days written notice before a fine,” and the HOA sent 10 days, that is a breach. Full stop. Montana courts have enforced HOA CC&Rs as contracts, which means procedural failures are as meaningful as substantive ones.
| Montana | Florida | California | |
|---|---|---|---|
| Comprehensive HOA Act | No | Yes (Ch. 720) | Yes (Davis-Stirling) |
| Statutory fine cap | None | None | None |
| Notice required by statute | No | Yes (14 days) | Yes (§5855) |
| Hearing required by statute | No | Yes | Yes |
| Retroactive rule protection | Yes (§70-17-901) | No equivalent | Limited |
| Political sign protection | Yes (§70-1-522) | Yes (§720.304) | Yes (§4710) |
Montana courts treat CC&Rs as binding contracts between the association and each homeowner. That framing has two important consequences.
First, the HOA must follow every procedural step the CC&Rs require — not just the ones it finds convenient. Notice period, cure opportunity, hearing if required by the documents, fine amount authorized by the schedule. Each step is a contractual obligation.
Second, if the HOA misses any step, it has breached its own contract. That breach is a defense to the fine regardless of whether the underlying violation is legitimate. You do not need to prove the violation did not occur. You only need to show the HOA did not follow its own procedure.
Practical Example
Your CC&Rs require 14 days written notice before a fine is imposed. Your HOA sent a violation notice on Monday and a fine notice on the following Thursday — 10 days later. That is a breach of contract. The fine is procedurally defective regardless of whether you actually violated the rule. In Montana, that defense wins.
The practical checklist: pull your CC&Rs and bylaws, find the enforcement section, and map every step the HOA was required to take. Notice requirements. Cure period. Hearing rights if any. Fine amounts authorized. Then compare that map to what the HOA actually did. Every gap is a defense.

Montana enacted SB 300 in 2019, codified at MCA §70-17-901. This statute does one specific thing with significant impact: it prohibits HOAs from imposing more onerous restrictions on existing homeowners than existed at the time of their purchase — without written consent.
The types of use protected under §70-17-901:
The written-consent exception: an owner can agree to a new, more onerous restriction — but only in writing, and that written consent binds only the consenting owner. The HOA cannot impose a new restriction on all homeowners by board vote alone if it is more onerous than what existed at the time of purchase.
How to invoke it: Identify the rule being enforced and find when it was adopted. If that rule was adopted after your purchase date and is more onerous than what existed at the time you bought, request a formal exemption from the HOA in writing citing MCA §70-17-901. The HOA must record any restriction properly with the county clerk. If the restriction was never properly recorded or was adopted without your written consent, its enforceability is directly challenged by §70-17-901.
Practical Example
You purchased your home in 2017. When you bought, the CC&Rs had no restrictions on short-term rentals. In 2022, the HOA board adopted a new rule banning Airbnb and short-term rentals and is now fining you for listing your property. Under MCA §70-17-901, that 2022 rule is unenforceable against you unless you provided written consent at the time it was adopted. Your rental activity at the time of purchase was protected use — the HOA cannot retroactively strip that right without your written agreement.
This is Montana's most powerful HOA statute because it applies to some of the highest-stakes disputes: rental bans, development restrictions, commercial use changes. If your fine relates to an activity that was permitted when you purchased, §70-17-901 is your first line of defense.
MCA §70-1-522 is straightforward: HOAs in Montana cannot prohibit political signs on an owner's property that advocate the election, appointment, or defeat of a candidate for public office.
What is allowed under §70-1-522: reasonable restrictions on sign size, placement, and duration. What is not allowed: an outright ban on political signs, or a rule that effectively prohibits them through size and placement requirements so restrictive that no sign could comply.
Critically, §70-1-522 applies to both planned communities and condominiums. Whether your HOA is a traditional subdivision or a condo association, this protection applies.
Practical Example
Your HOA fined you for displaying a yard sign supporting a school board candidate. Under MCA §70-1-522, that fine is unenforceable. Political signs for candidates for public office cannot be banned by an HOA in Montana. Send a written dispute letter citing §70-1-522 and request the fine be rescinded.

Because Montana has no comprehensive HOA act, your process is rooted in contract enforcement rather than statute citation. Here is the exact sequence.
Get your complete governing documents
Request the full set: CC&Rs, bylaws, rules and regulations, and the fine schedule. If the HOA fails to provide them, check with your county clerk's office — recorded documents are public record. You cannot defend yourself without knowing exactly what the HOA's own contract requires.
Find the enforcement procedure in your CC&Rs
Look for the enforcement section — usually labeled "Enforcement," "Violations," or "Fines and Penalties." Note every required step: required notice period (number of days, written or certified mail), opportunity to cure, hearing process if any, fine amounts authorized.
Identify every procedural step the HOA missed
Map the required steps against what the HOA actually did. Wrong notice period? Certified mail required but sent via email? Hearing required but never offered? Fine amount exceeds what the schedule authorizes? Each missed step is a breach of contract defense.
Check for the MCA §70-17-901 defense
Find when the rule being enforced was adopted. If it was adopted after your purchase date and restricts residential, agricultural, commercial use, rental ability, or development more than existed at purchase, you may be protected under MCA §70-17-901 — unless you gave written consent to the new restriction.
Check for MCA §70-1-522 if the violation involves a political sign
If your fine is for a political sign advocating a candidate's election, appointment, or defeat, §70-1-522 bars the fine outright. Reasonable size, placement, and duration rules are allowed — a ban is not.
Write a formal dispute letter
Address it to the HOA board in writing. Cite the specific CC&R sections that govern enforcement and identify each procedural requirement the HOA failed to meet. If MCA §70-17-901 or §70-1-522 applies, cite the statute directly. State clearly that the fine is procedurally defective and demand it be rescinded. Keep a copy.
Escalate if the HOA refuses
Montana small claims court handles disputes up to $7,000 — no attorney required. For larger amounts, district court is the venue. Filing a small claims complaint is inexpensive and often motivates settlement before a hearing. There is no state regulatory agency that handles Montana HOA complaints.
Not every Montana HOA fine is worth fighting. Here are three situations where paying and moving on is the rational choice.
The violation is legitimate and the process was followed correctly
If you pull the CC&Rs and confirm the HOA followed every required step — correct notice period, proper cure opportunity, fine within the authorized schedule — and the underlying violation genuinely occurred, paying may be the most efficient resolution.
The fine is small and the time cost exceeds it
Fighting a $50 fine through small claims court costs $30 to file, half a day in court, and significant stress. If the procedural defects are minor and the fine is small, a cost-benefit analysis may favor payment.
You are planning to sell
Unpaid HOA fines can complicate a sale and give a buyer leverage in negotiations or delay closing. If a sale is imminent, clearing outstanding fines — even disputed ones — may be the pragmatic choice.
Does Montana have an HOA act?
No. Montana has no comprehensive HOA statute for planned communities. HOAs are governed by their own CC&Rs, the Montana Nonprofit Corporation Act (MCA Title 35, Ch. 2), and specific protections in MCA §70-17-901 and §70-1-522. Condominiums that opted in via recorded declaration are also governed by the Montana Unit Ownership Act (MCA §70-23-101).
Can an HOA in Montana fine me without a hearing?
Only if your CC&Rs allow it. There is no Montana statute requiring a hearing before a fine. Your governing documents define the process — if they require a hearing and your HOA skipped it, that's a breach of contract and a defense.
What's the maximum HOA fine in Montana?
No state-law cap exists. The cap, if any, is set by your CC&Rs or fine schedule. If your HOA fined you more than the CC&Rs authorize, the excess is unenforceable.
Can my Montana HOA make new rules after I bought my home?
Generally, more onerous restrictions cannot be enforced against you without your written consent under MCA §70-17-901 (enacted via SB 300, 2019). This covers new restrictions on residential, agricultural, commercial use; rental ability; and development.
Who regulates HOAs in Montana?
No state agency regulates HOAs in Montana. Disputes are resolved through civil court — small claims court for amounts under $7,000, district court for larger disputes.
Can my Montana HOA stop me from displaying a campaign sign?
No. MCA §70-1-522 explicitly prohibits HOAs from restricting political signs advocating the election, appointment, or defeat of a candidate. Reasonable size, placement, and duration restrictions are allowed, but outright prohibition is not.
