Water, Power, and Infrastructure: The Practical Guide for Los Cabos Property Buyers
Los Cabos sits at the tip of a 1,000-mile desert peninsula, hundreds of miles from the nearest mainland infrastructure. For American buyers accustomed to reliable utilities delivered through established systems, understanding how water, electricity, internet, and other services work in Baja California Sur is essential — both for day-to-day living and for evaluating the long-term value of any property investment.
This guide covers the infrastructure realities that every buyer should understand before purchasing property in Los Cabos.
Water: The Most Critical Resource
Water is the defining infrastructure challenge in Baja California Sur. The state receives less than 10 inches (250mm) of rainfall annually, and the growing population and tourism industry are placing increasing pressure on underground aquifers. Understanding water supply is arguably the single most important due diligence item for any property purchase.
Municipal Water (OOMSAPAS)
OOMSAPAS (Organismo Operador Municipal del Sistema de Agua Potable, Alcantarillado y Saneamiento) is the municipal water authority for Los Cabos. Key facts:
- Municipal water is generally reliable in established neighborhoods and communities
- Water quality varies — most residents and expats use bottled or filtered water for drinking
- Service interruptions can occur, particularly during peak summer months. Cisterns (water storage tanks) are standard in most homes
- Monthly water bills are modest: $20-$80 USD for residential properties
Well Water
Properties outside of municipal service areas may rely on private wells:
- Well permits (concesiones) are issued by CONAGUA (Comisión Nacional del Agua)
- Obtaining new well permits has become increasingly difficult as aquifer management has tightened
- Properties with existing well permits and proven water production are significantly more valuable than those without
- Water quality from wells varies — testing is essential before purchase
Desalination
Desalination is becoming a critical part of the Los Cabos water strategy:
- Several large-scale desalination plants are operational or under construction in the region
- Many luxury developments (Costa Palmas, Diamante, Quivira) operate their own private desalination plants, providing reliable water supply independent of municipal systems
- Residential-scale desalination units are available for individual homes ($15,000-$50,000 installed)
- The cost of desalinated water is higher than municipal water but provides reliability and quality assurance
Water Storage
Every home in Los Cabos should have a cistern (tinaco or aljibe) — a water storage tank that provides a buffer during supply interruptions:
- Rooftop tinaco: 1,100-5,000 liter tanks on the roof providing gravity-fed water. Standard in most Mexican construction.
- Underground aljibe: Larger storage tanks (5,000-50,000+ liters) buried underground with pump systems. Common in luxury homes.
- Recommended capacity: Minimum 3-5 days of household water supply
Electricity (CFE)
Electricity in Baja California Sur is supplied by CFE (Comisión Federal de Electricidad), Mexico's state-owned power company.
Key Considerations
- Tiered pricing: Mexico uses a tiered system where rates increase dramatically with consumption. The basic residential tariff (1-1B) provides subsidized rates for the first ~1,000 kWh/bimonthly. Above that, the DAC (Doméstica de Alto Consumo) tariff kicks in at approximately 3-4x the base rate.
- Air conditioning impact: In a desert climate, AC is the largest electricity consumer. A luxury home running AC year-round can easily exceed the DAC threshold, resulting in bills of $500-$2,000+ USD per month.
- Power outages: Brief outages occur periodically, particularly during storms. Backup generators are standard in luxury homes ($5,000-$25,000 installed).
- Voltage: Mexico uses 120V/60Hz, the same as the United States. Electrical outlets and plugs are compatible with U.S. devices.
Solar Power
Los Cabos is ideal for solar energy, with over 300 days of sunshine annually:
- Residential solar systems typically cost $15,000-$40,000 for a full installation
- Mexico's net metering program allows homeowners to sell excess power back to CFE, effectively zeroing out their electric bill
- ROI on solar installations is typically 3-5 years, making it one of the best investments for homeowners
- Many luxury developments now include solar as standard in new construction
Internet and Communications
Internet connectivity in Los Cabos has improved dramatically in recent years, making remote work and digital lifestyles fully viable:
- Fiber optic: Available in many established neighborhoods and all major developments. Speeds of 100-500 Mbps from providers like TotalPlay and Megacable.
- Cable internet: Available through Megacable and other providers. Speeds of 50-200 Mbps.
- Starlink: Increasingly popular for rural or underserved areas. Provides 50-200 Mbps with low latency. Initial equipment cost approximately $500 USD with monthly service around $50-$75.
- Mobile data: 4G/LTE coverage is extensive throughout Los Cabos from Telcel, AT&T Mexico, and Movistar. 5G is rolling out in urban areas.
Natural Gas and Propane
Los Cabos does not have natural gas infrastructure. All gas-powered appliances use propane (LP gas):
- Propane is delivered by truck and stored in tanks (stationary or portable)
- Monthly propane costs for a typical home: $50-$150 USD
- Many luxury homes are going all-electric to avoid propane dependency
Sewage and Wastewater
- Municipal sewer service is available in established areas of Cabo San Lucas and San José del Cabo
- Properties outside municipal service areas require septic systems or private treatment plants
- Luxury developments typically operate their own wastewater treatment plants, often recycling treated water for landscape irrigation
Infrastructure Due Diligence for Buyers
Before purchasing any property in Los Cabos, verify:
- Water source: Municipal connection, private well, or desalination? What's the backup?
- Water rights: If the property has a well, does it have a valid CONAGUA concession?
- Electrical capacity: Is the CFE service adequate for the property's needs? What's the tariff classification?
- Internet availability: Can you get fiber or reliable broadband at the property?
- Sewer/septic: Municipal connection or septic system? When was the septic last serviced?
- Road access: Is the access road public or private? Who maintains it?
Infrastructure may not be as glamorous as ocean views or golf courses, but it's the foundation that determines whether a property is truly livable — and whether its value will appreciate or stagnate over time. Properties with robust, redundant utility systems command premiums for good reason.
