Winterizing Your Mobile Home Park: A Practical Guide for Midwest Owners

Winter in the Midwest can be unforgiving, particularly for mobile home park owners responsible for aging infrastructure, exposed water lines, and a mixture of park-owned homes (POHs) and tenant-owned homes (TOHs).

In Nebraska, Iowa, South Dakota, Minnesota, and surrounding states, extended periods of subzero temperatures, high winds, and deep frost can turn a relatively minor maintenance issue into an expensive emergency.

A successful winterization program begins long before the first freezing temperatures arrive. It starts with establishing clear expectations in your lease agreements and community rules, including minimum indoor thermostat temperatures, responsibilities for maintaining adequate heat, and identifying who is responsible for inspecting, maintaining, and repairing vulnerable components such as water lines, heat tape, insulation, and skirting.

These responsibilities can vary significantly between park-owned and tenant-owned homes. Establishing them in advance and communicating expectations to residents before winter helps prevent misunderstandings, encourages early reporting of problems, and reduces the potential for costly emergency repairs.

Of course, written policies are only one part of an effective winterization program. Owners and managers should also physically inspect their infrastructure, identify recurring problem areas, and complete preventive maintenance before severe weather arrives.

For mobile home park operators, winterization isn't simply about keeping pipes from freezing. It's about protecting infrastructure, maintaining essential services, reducing unexpected expenses, and preparing both the property and its residents for the challenges of a Midwest winter.

Here are several areas every Midwest mobile home park owner should evaluate before winter arrives.

Set a Halloween Deadline

One rule of thumb I've followed throughout my years of mobile home park ownership is simple: Have your winterization completed by October 31 - Halloween.

It's an easy date to remember and provides a practical deadline for inspecting water lines, checking heat tape, repairing insulation, and addressing other cold-weather vulnerabilities.

Of course, freezing temperatures can arrive well before November in the upper Midwest, so don't wait until Halloween to begin the work. Instead, use October 31 as your final completion deadline, adjusting earlier when weather conditions require it.

The goal is to have your park ready for winter before winter decides to arrive rather than after.

1. Inspect Water Risers, Heat Tape, and Pipe Insulation

Water service connections are among the most vulnerable components of a mobile home park during extreme cold.

Pay particular attention to water risers extending from the ground, exposed piping beneath homes, and connections entering utility closets.

Inspect existing heat tape for deterioration, damaged connections, and proper operation. Where additional protection is needed, use heat tape specifically approved for the pipe material and installation conditions.

Proper insulation is equally important. It helps retain heat and reduces exposure to cold air. Always follow the heat tape manufacturer's installation instructions, particularly when it comes to insulation and whether the heat tape can overlap.

Operator Pro Tip: Identify homes with a history of frozen water lines. Those locations deserve additional attention to prevent a recurring freeze-up each time the temperature drops.

2. Examine Skirting and Underbelly Conditions

Manufactured homes are particularly susceptible to cold air entering through damaged skirting, missing access panels, and openings around utility connections.

Walk the perimeter of each park-owned home and inspect for loose panels, gaps, and damaged sections.

Underneath the home, look for exposed plumbing, leaks, sewer backups, missing insulation, and deteriorated underbelly material.

The objective is twofold. First, to keep cold air from getting underneath the home while still allowing for proper ventilation. Second, to ensure there are no surprises that could clearly have been addressed while it was warm out.

Operator Pro Tip: For tenant-owned homes, provide written reminders of the importance of maintaining skirting and protecting exposed plumbing. After all, how they prepare for winter can directly impact your park’s infrastructure. Having documented reminders can help settle disagreements over who's responsible for repair expenses when freezing does occur.

3. Don't Overlook Water Heater Closets

Exterior-access water heater closets are common in older manufactured homes, and they're frequently overlooked during winter preparation.

Even when the water heater operates properly, the surrounding plumbing may be vulnerable to freezing.

Inspect the hot and cold water connections, openings around pipes coming through the floor, insulation, and exterior access door.

Most external water heater closets share walls with heated interior spaces, providing a degree of protection. However, that shouldn't be mistaken for guaranteed freeze protection during prolonged subzero weather.

A poorly sealed and insulated access door can still allow freezing temperatures to reach plumbing that would otherwise remain protected. One method I’ve used over the years was to safely hang insulation inside the closet door’s frame while making sure the insulation doesn't crowd or come into contact with the water heater.

Regardless of how you insulate the closet, make sure the water heater still has the fresh air it needs to operate safely. This is especially important with gas water heaters, which are typical within exterior water heater closets.

Operator Pro Tip: Years ago, many operators counted on gas water heaters to help keep exterior closets warm. However, today's more efficient and better-insulated water heaters often give off much less heat. Don't assume the water heater alone will keep the surrounding plumbing from freezing.

4. Service Heating Systems Before They're Needed

For park-owned homes, preventive furnace maintenance can help prevent costly emergency after-hours service calls.

Inspect furnace operation, replace dirty filters, examine venting, and verify thermostats are functioning properly and have fresh batteries in modern digital thermostats.

Smoke alarms and carbon monoxide detectors should also be checked, with particular attention to older homes and heating equipment.

Encourage residents to report heating problems immediately rather than waiting until the home becomes dangerously cold.

For tenant-owned homes, homeowners typically maintain their own heating systems. Nevertheless, a heating failure can quickly become a community concern when frozen plumbing threatens shared infrastructure.

Operator Pro Tip: One practice I've followed for years with my park-owned homes is including a minimum thermostat temperature requirement for winter months in the lease. While this doesn't guarantee tenants will follow the rules, it helps establish responsibility when recurring freeze-ups result from a tenant turning down the thermostat or relying on other sources of heat.

5. Establish Clear Written POH and TOH Responsibilities

Nobody likes more paperwork. However, including a few basic winter maintenance requirements in your lease agreements can help prevent last-minute emergencies when freezing temperatures arrive.

Obviously, how you do that depends on the mobile home park and whether it is a POH or TOH.

For POHs, management generally handles home-related maintenance, including water-line protection, heating equipment, and exterior conditions.

For TOHs, homeowners generally maintain their own homes, including skirting, heat tape, and plumbing beyond the park's responsibility.

However, responsibility for service connections and utility infrastructure can vary from park to park. So, your park’s lease agreements and community rules should address these responsibilities well before winter comes.

Clearly establishing written requirements for minimum thermostat temperatures, responsibility for water and sewer lines, and maintenance of skirting and other exterior components can dramatically reduce an owner's headaches when freezing temperatures arrive.

Before winter arrives, provide residents with a written reminder of these requirements. This not only keeps expectations fresh in everyone's mind but also gives management a consistent set of guidelines to follow throughout the winter.

6. Prepare the Grounds and Utility Infrastructure

Winter preparation should extend well beyond inspecting the individual homes. Your park's underground utilities, roads, drainage, and access to emergency repairs deserve just as much attention.

Start with your water shutoffs and curb stops. Make sure they're accessible, functioning properly, and clearly marked so they can be located beneath snow and ice. If you have curb stops that haven't been operated in years, fall is a much better time to discover they don't work than during a January water emergency.

Address known water leaks and sewer problems before the ground freezes. A repair that might take a couple of hours in October can become an expensive, all-day project when you're dealing with deep frost lines underground and subzero temperatures.

Inspect drainage areas, remove debris that could interfere with snow removal and thaw runoff, and identify trees or branches that could damage homes or utility lines during heavy snow and ice storms.

Make arrangements for snow removal well before the first major storm. While this seems like a no-brainer, you'd be surprised how many out-of-state park owners wait until the first big snowfall to start looking for someone. Make sure your snow removal provider understands which roads, entrances, and areas need priority attention.

Finally, make sure you, your manager, and any backup personnel have an updated list of water shutoff locations, utility contacts, plumbers, and other emergency service providers. Time is often not on your side with winter emergencies such as broken water lines. If you or your manager is unavailable, someone else should still be able to locate a shutoff and arrange for repairs.

Operator Pro Tip: Don't wait until an emergency to find out whether your local plumber or excavation contractor offers after-hours service. Establish those relationships well before winter and keep their contact information readily available. When a water line breaks at 2 AM in January, that's not the time to start looking for someone willing to come out and get the water shut off.

Final Thoughts

When it comes to winterizing a mobile home park, a little preventive maintenance can save thousands of dollars in emergency repairs and a lot of unnecessary headaches.

For Midwest mobile home park owners, the greatest risks often come from relatively small vulnerabilities: an exposed water riser, a missing access panel, a poorly sealed water heater closet, or a furnace that failed in the middle of the night due to low batteries during a snowstorm.

Addressing these concerns before winter arrives helps protect residents, preserve infrastructure, and reduce unexpected operating expenses.
