Keep the lawn green. Keep the tenants happy. Keep the HOA from sending notices. Make sure the sprinkler system runs often enough that the yard does not become a problem.
In a normal summer, that approach may be simple enough. This summer is not shaping up to be normal.
Denver Water has declared a Stage 1 drought and is asking customers to reduce total water use by at least 20%. To help reach that goal, mandatory outdoor watering is now restricted to two assigned days per week, with watering only allowed before 10 a.m. or after 6 p.m.
That alone would be enough to change how rental owners should think about landscape maintenance this season. But the restrictions are only part of the story.
Denver Water has also approved temporary drought pricing on outdoor water use, beginning with May 2026 water use and showing up on June 2026 bills. The drought pricing is currently set to remain in place through April 30, 2027, unless the Denver Board of Water Commissioners takes further action. Repeated watering violations can also trigger escalating charges, starting with a warning and increasing from there.
For landlords, this is where a simple watering rule can become an operational issue very quickly. Because rental properties rarely involve just one person making one decision.
Sometimes the owner pays the water bill, but the tenant controls the sprinkler system. Sometimes the tenant is responsible for lawn care, but does not understand the watering schedule. Sometimes a landscaper sets the irrigation timer months ago and has not updated it. Sometimes the HOA expects one standard of appearance while Denver Water is enforcing another standard of conservation. Sometimes everyone assumes someone else is paying attention.
That is where problems begin.
The Rules Are Simple. The Rental Property Reality Is Not.
Under Denver Water’s Stage 1 drought restrictions, single-family residential properties are assigned watering days based on address. Even-numbered addresses may water on Sunday and Thursday. Odd-numbered addresses may water on Wednesday and Saturday. All other customers, including multifamily properties and commercial properties, may water on Tuesday and Friday.
Outdoor watering is only allowed before 10 a.m. or after 6 p.m. Denver Water also says customers should not water during rain or high winds, should keep water off pavement, sidewalks, and streets, and should repair leaking or broken sprinkler systems within 10 days.
On paper, that sounds simple. In practice, landlords should be asking a much more important question: Who is actually making sure that is happening at the property?
That question matters because many rental properties are set up around habits, not active systems. The sprinkler timer may still be programmed for three or four days per week. A tenant may be hand-watering at the wrong time of day. A broken sprinkler head may be spraying the sidewalk every morning before anyone notices. A landscaper may be maintaining the yard according to the old schedule unless someone tells them otherwise.
And for owners who are not local, are not checking the property regularly, or are relying on tenants to report issues accurately, those details can go unnoticed until they become more expensive.
This is exactly the kind of thing that tends to catch landlords off guard.
Not because the rule is impossible to understand, but because the follow-through requires coordination.
A Green Lawn May Not Be the Right Goal This Summer
One of the hardest parts of this summer may be resetting expectations.
Many owners still evaluate landscape maintenance by appearance. If the lawn is green, the property feels well cared for. If the lawn starts to brown, it can feel like neglect. That instinct is understandable, especially for owners who used to live in the property and still remember how the yard looked when they maintained it themselves.
But this year, a perfectly green lawn may not be the most realistic or responsible benchmark.
With watering restricted to two assigned days per week, Denver landlords should expect more visible lawn stress during hot, dry stretches. Some dry patches may be unavoidable. Turf may look different than it has in previous summers. Certain areas of the yard may not recover as quickly. And in some cases, the right maintenance decision may be to prioritize trees, shrubs, perennials, and long-term landscape health over keeping every inch of grass looking perfect.
Grass can usually recover from seasonal stress more easily than mature trees or established shrubs. Losing long-term plantings can create much larger replacement costs for the owner. Denver Water’s drought guidance also allows trees, shrubs, perennials, annuals, and vegetables to be watered on any day using a hand-held hose or low-volume, non-spray irrigation, as long as watering does not occur between 10 a.m. and 6 p.m.
That means owners should not think about the yard as one uniform category.
The lawn, the trees, the shrubs, the garden beds, the irrigation system, and the tenant’s day-to-day behavior may all need to be managed differently.
For self-managing landlords, this is often where things get complicated. The lease may say the tenant is responsible for lawn care, but does the tenant understand drought watering rules? Does the lease explain what happens if a city or utility rule limits watering? Does the owner know whether the sprinkler system is functioning properly? Has anyone told the tenant that some browning may be expected this season? Has anyone documented what condition the yard was in before the hottest part of the summer?
Those are not theoretical questions. They are the kinds of details that determine whether a stressful summer turns into a tenant dispute, an owner frustration, a surprise bill, or an avoidable maintenance issue.
Drought Pricing Adds Another Layer
The other piece landlords should understand is the billing side.
Denver Water’s temporary drought pricing applies to outdoor water use. For residential customers, Tier 1 water use, which is meant to cover essential indoor use, is exempt from the temporary drought charge. Tier 2 water use receives an added drought charge of $1.10 per 1,000 gallons, and Tier 3 receives an added drought charge of $2.20 per 1,000 gallons. These charges are added on top of existing 2026 water rates.
That may not sound dramatic at first glance.
But for rental properties with irrigation systems, large yards, inefficient sprinkler heads, leaks, or tenants who are trying to keep the lawn greener than the restrictions realistically allow, outdoor water use can climb quickly.
This is especially important because many landlords misunderstand how water responsibility works when a tenant is involved. Denver Water allows tenants to be added to an account and invoiced, but the landlord or owner’s name remains on the account. Denver Water’s landlord/tenant policy states that landlords are ultimately responsible to Denver Water for financial charges incurred on the account.
In other words, an owner may be able to address water costs with the tenant through the lease, but that does not necessarily remove the owner from the account-level responsibility with Denver Water.
That distinction matters during a drought.
If a tenant over-waters, ignores a leak, runs sprinklers during restricted hours, or fails to report a broken irrigation issue, the owner may still be pulled into the financial consequences. If the owner is not receiving duplicate bills, monitoring usage, or checking whether outdoor consumption has changed, the problem may not be obvious until after the cost has already occurred.
Violations Can Escalate
Denver Water’s current enforcement structure also creates another reason for landlords to pay attention.
For single-family residential customers, Denver Water lists the first watering violation as a warning. The second violation is listed at $250, the third at $500, and the fourth at $1,000.
That should get the attention of rental owners.
A tenant watering on the wrong day may not feel like a major issue in the moment. A sprinkler system running at the wrong time may feel like a small mistake. Overspray hitting a sidewalk may feel like something that can be dealt with later. But repeated violations can become expensive, and the owner may not be the person physically creating the violation.
That is one of the unique challenges of rental ownership.
The person with day-to-day control of the property is not always the person who absorbs the long-term cost or liability. And unless expectations are clear, documented, and actively managed, both owners and tenants can end up frustrated.
The tenant may feel blamed for rules they did not understand.
The owner may feel blindsided by charges or landscape decline.
The property manager may have to sort out what happened after the fact.
And the yard itself may suffer because no one adjusted the plan early enough.
This Is Also a Tenant Communication Issue
For landlords, one of the most important steps this summer is communication.
If tenants are responsible for watering, they should not be left to figure out the drought rules on their own. They should know which days apply to the property, what times watering is allowed, what counts as water waste, and what to do if they notice a broken sprinkler head, leak, pooling water, or runoff.
They should also understand the owner’s expectations.
That may include explaining that some lawn stress is expected this summer. It may include clarifying that tenants should not over-water in an attempt to keep the lawn perfectly green. It may include giving specific instructions about trees, shrubs, and garden areas. It may include asking tenants to report irrigation issues immediately instead of assuming the problem is minor.
This is where many self-managing landlords unintentionally create conflict. They assume the lease language is enough. But lease language does not automatically create practical understanding.
A tenant may technically be responsible for yard care while still having no idea how the sprinkler system works, what the new watering days are, how drought pricing affects the property, or whether the owner would prefer a less green lawn over higher usage and potential violations.
When expectations are not clearly communicated, everyone fills in the gaps differently.
The owner thinks the tenant should know better.
The tenant thinks they are doing their best.
The lawn becomes the evidence in the middle.
This Is a Good Time to Review Irrigation Systems
This summer is also a good reminder that irrigation systems are not “set it and forget it” systems.
A sprinkler timer that worked last year may be wrong this year. A system that was efficient in May may need adjustment in July. A broken head can waste significant water before anyone notices. Overspray can put water onto sidewalks, driveways, streets, or alleys. Poor coverage can leave some areas soaked and others dry.
During drought restrictions, those problems matter more.
Owners should be thinking about whether irrigation schedules have been updated to match assigned watering days, whether sprinklers are running only during permitted hours, whether there are leaks or broken heads, and whether the system is watering efficiently instead of simply running longer.
This is also where the emotional side of owning a rental property can interfere with good decision-making.
Owners who are attached to the property may want the yard to look exactly the way it looked when they lived there. They may see browning grass as a personal failure or as tenant neglect. But a rental property has to be managed based on current conditions, not memory.
And the current conditions are different.
This summer, protecting the property may mean accepting a less-than-perfect lawn while focusing on compliance, water efficiency, communication, and long-term landscape survival.
The Bigger Takeaway for Landlords
Most landlords can understand the watering rule once it is explained.
The harder part is building the system around it.
That means knowing who is responsible for watering. Confirming which watering days apply. Updating sprinkler timers. Communicating expectations to tenants. Watching water usage. Responding quickly to leaks. Coordinating landscapers. Understanding billing responsibility. Documenting property condition. And resetting owner expectations before the lawn starts showing stress.
That is the part many self-managing landlords underestimate.
They think of property management as collecting rent, finding tenants, and handling repairs when something breaks. But rental ownership is increasingly shaped by operational details that shift from season to season: new laws, new utility rules, new market conditions, new tenant expectations, and new risks that do not always announce themselves loudly before they become a problem.
Denver’s drought restrictions are a good example.
This is not the most complicated rule landlords will ever face. But it touches multiple parts of the rental relationship at once: maintenance, billing, tenant communication, vendor coordination, curb appeal, compliance, and owner expectations.
That is why it matters.
A lawn that looks a little stressed this summer may not be the real problem.
The real problem is when no one knows who is watching the details.
