Energy efficiency in rental properties is no longer optional for smart landlords. Tenants increasingly prioritize energy costs when choosing rentals, and regulatory requirements are tightening. This guide covers landlord obligations, investment strategies, and tax benefits.
Why Landlords Should Care About Energy Efficiency
Financial Benefits
- Higher rents: Energy-efficient rentals command 3-7% higher rents (NAR, 2025)
- Lower vacancy: Tenants stay longer in comfortable, affordable-to-operate units
- Reduced maintenance: Efficient HVAC and well-sealed homes have fewer service calls
- Tax deductions: All energy improvements are deductible as business expenses
Tenant Expectations
- 63% of renters consider energy costs when choosing a rental (National Apartment Association, 2024)
- Energy-efficient features (smart thermostat, LED lighting, efficient appliances) are among the most requested amenities
- High energy bills are a top complaint that drives tenant turnover
Regulatory Trends
Several jurisdictions now require energy efficiency in rental properties:
- Portland, OR: Energy disclosure required at time of sale/rental
- Boulder, CO: SmartRegs require rental properties to meet minimum energy efficiency standards
- Austin, TX: Energy audit required for multifamily buildings
- New York City: Local Law 97 sets emissions caps for larger buildings
Landlord Obligations by Jurisdiction
Mandatory Requirements (Selected Cities)
| Jurisdiction | Requirement | Applies To |
|---|---|---|
| Boulder, CO | SmartRegs energy efficiency standards | All rental properties |
| Portland, OR | Home Energy Score disclosure | All residential sales/rentals |
| Austin, TX | Energy audit for multifamily | Buildings with 10+ units |
| NYC | LL97 emissions caps | Buildings 25,000+ sq ft |
| Berkeley, CA | Natural gas ban (new construction) | New buildings |
Best Practice (No Mandate)
Even without legal requirements, conducting an energy audit and making improvements is financially smart and reduces legal liability related to habitability claims.

Tax Benefits for Landlords
Deductible Expenses (Schedule E)
Landlords can deduct 100% of energy-related expenses:
- Energy audit costs ($200-$600)
- Air sealing and insulation (deducted or depreciated)
- HVAC maintenance and repair
- Utility costs (if landlord pays)
- Smart thermostat and monitoring devices
Depreciation
Major improvements (HVAC, water heater, insulation) can be depreciated over their useful life:
- HVAC systems: 27.5 years (residential rental property component)
- Appliances: 5-7 years
- Insulation and air sealing: 27.5 years (structural improvement)
Section 179 / Bonus Depreciation
Some energy improvements may qualify for accelerated depreciation, allowing larger deductions in the first year. Consult a tax professional for your specific situation.
Tax Credits (Limited for Rentals)
- Section 25C (home improvement credits): NOT available for rental properties
- Section 25D (solar): Available for both primary and secondary residences but NOT rental-only properties
- Depreciation deductions typically exceed the value of unavailable credits
Energy Audit Process for Rental Properties
When to Audit
- Before purchasing a rental property (due diligence)
- Before major renovations
- When tenant complaints about comfort or energy costs arise
- Every 5-10 years as part of maintenance planning
- When local regulations require it
What to Tell Your Auditor
- Typical occupancy and tenant behavior
- Which utilities you pay vs. tenant pays
- Budget constraints and timeline
- Whether you plan to raise rents after improvements
- Any pending renovations that could incorporate efficiency work

Frequently Asked Questions
Can I pass energy improvement costs to tenants through higher rent?
Yes, but strategically. Improvements that reduce tenant utility costs justify modest rent increases. A $50/month rent increase after improvements that save the tenant $100/month in utilities is a win-win.
Should I pay for utilities or let tenants pay?
When landlords pay utilities, they have direct financial incentive to improve efficiency. When tenants pay, the landlord has less incentive (the "split incentive" problem). Consider including utilities in rent for energy-efficient units — it simplifies billing and allows you to capture the value of improvements through higher rent.
Are there energy tax credits for rental properties?
Federal Section 25C credits are NOT available for rental properties. However, all improvement costs are deductible as business expenses or depreciable, which provides tax benefits through a different mechanism. Section 25D (solar) is limited to properties that are your primary or secondary residence.
Can I require tenants to be energy-efficient?
You can include reasonable energy-related provisions in lease agreements, such as maintaining thermostat within certain ranges, not blocking vents, changing air filters, and reporting maintenance issues promptly.
What is the best energy improvement for a rental property?
Air sealing provides the best ROI for most rental properties — it reduces tenant complaints about comfort, lowers energy costs (whether you or the tenant pays), and costs only $500-$2,500 with a 1-4 year payback.
