Regimen Condominal: Understanding Mexico's Condo Regime Laws for Cabo Buyers

Every condo and townhouse in Los Cabos is governed by the regimen condominal — Mexico's condo regime law that defines what you own, what you share, how decisions get made, and what you pay. Most foreign buyers never read it before signing. That is a mistake that costs money and control later.

What Is the Regimen Condominal?

The regimen condominal is not an HOA agreement — it is a state property law framework that creates the legal structure for shared ownership. In Baja California Sur, it is governed by the Ley de Regimen de Propiedad en Condominio del Estado de BCS. Every condominium, townhouse community, and mixed-use development in Los Cabos operates under this law, from a 6-unit boutique project in El Tezal to a 300-unit resort complex in Cabo del Sol.

The regime is established through two primary documents that you should read — in full, in translation — before buying:

The Acta Constitutiva (Constitutive Act)

This is the founding charter of the condominium. It is filed with the Public Property Registry (Registro Publico de la Propiedad) and has the force of law. It defines:

• Unit boundaries: the exact physical limits of each private unit (your exclusive property)
• Common areas: everything outside private units — lobbies, pools, gyms, roads, parking, landscaping, structural elements
• Indiviso percentages: each unit's proportional share of common area ownership and expenses
• Voting thresholds: what percentage of indivisos is required for different types of decisions
• Developer rights and obligations: what the developer can and cannot do during the construction and sales phase
• Permitted uses: residential only, residential plus short-term rental, commercial, mixed use

This document is deliberately hard to amend — typically requiring 75% of total indivisos (not just those attending a meeting) to change fundamental provisions. That protects you from a future majority trying to redefine your property rights.

The Reglamento (Bylaws and Rules)

The reglamento is the operational rulebook. It covers:

• Fee amounts and payment schedules
• Late payment penalties (typically 2-5% per month in Los Cabos developments)
• Assembly meeting procedures and quorum requirements
• Pet policies, noise restrictions, and guest access rules
• Architectural modification restrictions
• Short-term rental policies (if permitted by the constitutive act)
• Common area reservation and use rules

The reglamento can be amended more easily — usually by a simple majority of attending owners at a properly convened assembly. Read it carefully: this is where you find out whether you can rent your unit on Airbnb, whether you can have a dog, and whether you can modify your terrace. See our HOA fees guide for what these rules mean for your monthly costs.

Understanding Your Indiviso

The indiviso is the concept most foreign buyers struggle with because it has no direct US equivalent. It is your proportional ownership share of the common elements of the property. If your unit's indiviso is 3.5%, you own 3.5% of the pool, 3.5% of the lobby, 3.5% of the parking structure, and 3.5% of every other common area. You also pay 3.5% of all common expenses.

Indivisos are typically calculated based on unit size relative to total project size, but developers have discretion to weight them by other factors:

• Square footage basis: a 200 m2 penthouse in a building totaling 4,000 m2 of private space = 5% indiviso
• Value basis: a penthouse might carry a higher indiviso than its square footage would suggest, reflecting its premium price and view
• Equal basis: some small projects assign equal indivisos to all units regardless of size

Your indiviso also determines your voting power. A unit with a 5% indiviso gets 5% of the total vote at assemblies. This means larger, more expensive units have more say in how the property is managed — which can be either an advantage or a frustration depending on where your unit falls.

Developer Control and the Transition to Homeowner Governance

In the early phases of a development, the developer controls the condominium. They hold the majority of indivisos (through unsold units), appoint the administrador (property manager), set the initial budget, and make all operational decisions. This is standard and necessary — someone has to run the property while it is being built and sold.

The critical question is: when does control transfer to homeowners? Under BCS law, the developer must convene a transition assembly once a threshold percentage of units are sold — typically 51-75%, specified in the constitutive act. At that assembly, homeowners elect a new administrador and assume governance responsibility.

Watch for these common issues during the transition period:

• Delayed transitions: developers who drag their feet on calling the transition assembly, sometimes for years past the threshold. The law provides remedies, but enforcement requires legal action
• Reserve fund deficits: developers who set artificially low fees during the sales phase to make the property attractive, leaving the HOA with insufficient reserves when homeowners take over. Ask for audited financial statements. See our HOA governance guide for what to demand
• Incomplete common areas: developers who sell enough units to trigger transition before finishing all promised amenities. Your purchase agreement should specify delivery timelines for amenities independently of the unit delivery

Assemblies and Voting Mechanics

The asamblea de condominios (condo assembly) is the governing body. Ordinary assemblies happen annually; extraordinary assemblies can be called for urgent matters. Here is how they work:

Quorum: First call requires 75% of total indivisos present or represented by proxy. If quorum is not met, a second call (usually 30 minutes later) requires only 51%. If that fails, a third call can proceed with whatever indivisos are present. This cascading quorum system means that absentee owners who do not send proxies effectively forfeit their voice.

Proxy voting: you can designate a representative to attend and vote on your behalf through a carta poder (simple power of attorney) or a poder notarial (notarized power of attorney). For routine assemblies, a simple carta poder is sufficient. For assemblies where you are voting on constitutive act amendments or major capital expenditures, a poder notarial provides stronger legal standing. See our property documents guide for the mechanics.

Foreign buyer rights: your voting rights are tied to your indiviso, not your nationality. Fideicomiso holders vote identically to Mexican nationals. The bank that holds your trust has no vote — you direct the bank, and the bank acts on your instructions.

Common Pitfalls for Foreign Buyers

After helping dozens of buyers navigate condo purchases across Palmilla, Chileno Bay, Marina Cabo, and other Los Cabos communities, these are the issues I see most often:

• Not reading the constitutive act: buyers rely on their agent's summary or the developer's brochure. The actual document may contain restrictions on rentals, pets, or modifications that the marketing materials glossed over
• Ignoring the indiviso calculation: buyers who discover their fees are disproportionately high after closing because their unit carries a penthouse indiviso on a mid-floor unit
• Missing the rental restriction: some regimes prohibit short-term rentals entirely, limit rental periods, or require homeowner assembly approval. If your investment thesis depends on Airbnb income, verify this before you sign
• Assuming US HOA norms apply: Mexican condo law differs in material ways — there are no board elections in the US sense, the administrador has broader powers than a US property manager, and fee collection remedies differ

The Bottom Line

The regimen condominal is the legal DNA of your condo purchase. Every fee you pay, every rule you follow, every vote you cast, and every modification you make is governed by this document. Having your attorney review the acta constitutiva and reglamento before you sign is not a nice-to-have — it is as fundamental as the title search and the property inspection.

Ask for the documents in advance. Get them translated. Understand your indiviso and what it means for your fees and your vote. Know when the developer transition happens and what condition the reserve fund is in. The buyers who do this homework own their condo with clear expectations. The ones who skip it learn the hard way.
