When investors evaluate a mobile home park, they often focus on lot rent, occupancy, and location. However, one factor can quietly shape returns more than many expect: how the community gets its water and handles its sewer. Understanding public vs private utilities may help investors spot both opportunity and risk before they commit capital.

Public vs Private Utilities in a Mobile Home Park: What Are They?

In simple terms, the difference comes down to who owns and maintains the infrastructure.

Public (Municipal) Utilities

With public utilities, the mobile home park connects to city or county water and sewer lines. The municipality typically treats the water, maintains the main lines, and handles its own regulatory compliance. Meanwhile, the mobile home park owner usually stays responsible for the pipes inside the property.

Private Utilities

With private utilities, the mobile home park owns and operates its own systems. These often include:

• Private wells for drinking water
• Septic systems for wastewater
• Lagoons or small on-site treatment plants

Private systems are common in rural areas. In fact, the EPA estimates that around 15% of the U.S. population, or over 43 million people, rely on private wells for drinking water. Similarly, the agency reports that more than one in five U.S. homes depend on septic systems.

Why Public vs Private Utilities Matter for Mobile Home Park Investments

Utilities can influence a mobile home park’s operating costs, risk profile, and financing. Therefore, investors may want to treat them as a core part of due diligence rather than an afterthought.

Regulatory Responsibility

Many first-time investors miss this detail. Under the federal Safe Drinking Water Act, a system that supplies water to at least 15 service connections, or serves an average of at least 25 people for at least 60 days a year, counts as a “public water system.” According to the EPA, these systems may be publicly or privately owned.

As a result, a mobile home park with its own well may face testing and reporting rules similar to those of a small town. This could mean hiring a licensed operator, sampling water routinely, and filing reports with the state. Falling behind on these requirements may lead to fines or costly corrective work.

Capital Expenditure Risk

Private systems age, just like roads and homes. Wells may need new pumps, pressure tanks, or treatment upgrades over time. Likewise, the EPA notes that septic tanks typically need pumping every three to five years, and neglected systems can fail. Lagoons and on-site treatment plants may carry even larger repair and compliance costs.

On the other hand, public utilities shift much of this burden to the municipality. Even so, the mobile home park owner may still face aging internal lines, leaks, and rising municipal rates.

Financing and Exit Strategy

Lenders often look closely at utility type. Many tend to favor a mobile home park on city water and sewer, since these properties may carry less environmental and operational risk. Consequently, public utilities could support more favorable loan terms and a wider pool of future buyers.

The Case for Each Option

Neither setup is automatically better. Instead, each comes with its own trade-offs.

Advantages of Public Utilities

Lower Operational Burden

The municipality handles treatment, testing, and major infrastructure. This can free up the operator to focus on occupancy, resident relations, and improvements.

Potentially Easier Financing

Because lenders may view municipal utilities as lower risk, financing and refinancing could be more straightforward.

More Predictable Costs

While city rates can rise, owners generally avoid large, unexpected system replacements.

Advantages of Private Utilities

Potential Pricing Opportunity

Some buyers avoid a mobile home park with private systems altogether. As a result, these properties may trade at a discount, which could create value for experienced operators who know how to manage them.

Greater Control

Owners may have more control over water costs and avoid sudden municipal rate increases.

Possible Connection Upside

In some cases, a city extends its lines close to a property. Connecting to municipal service could lower long-term risk and potentially lift value. However, tap fees and construction costs can be significant, so investors may want to weigh them carefully.

Utility Billing: Another Key Factor

Regardless of who supplies the water, billing structure matters. Historically, many mobile home park owners included water and sewer in lot rent. Today, more owners consider submetering or bill-back programs, where residents pay for what they use.

This approach may encourage conservation and could improve net operating income. That said, state and local rules vary widely, so owners may want to confirm what’s permitted before making changes.

Questions Investors May Want to Ask

Before investing, it may help to ask the operator or sponsor:

• Is the mobile home park on public or private water and sewer?
• If private, is the water system regulated as a public water system, and is it in compliance?
• How old are the wells, septic systems, or lagoons?
• Are there any notices of violation on record?
• Do residents pay for their own utility usage?
• Is a future municipal connection possible?

The Bigger Picture

Manufactured housing plays a major role in America’s affordable housing supply. Roughly 22 million people live in manufactured homes, and the National Manufactured Home Owners Association estimates there are about 45,000 manufactured home communities nationwide. With affordable housing in high demand, a well-run mobile home park may continue to draw investor interest.

Ultimately, utilities don’t automatically make a mobile home park a good or bad investment. Rather, they shape the risk profile, the capital plan, and the level of operating expertise required. Investors who understand these differences may be better positioned to evaluate opportunities with clear eyes.
