What is NAICS 531110?#

NAICS 531110 falls under the broader sector 53: Real Estate and Rental and Leasing, and specifically the subsector 531: Real Estate. The official NAICS definition describes it as: “Establishments primarily engaged in the rental or leasing of residential buildings and dwellings, such as single-family homes, apartments, townhouses, and manufactured homes (excluding those operated by mobile home dealers).”

In simpler terms, this code covers businesses that own and rent out residential properties to tenants. Unlike property management companies (which may handle rentals on behalf of owners but don’t own the properties themselves—these are classified under NAICS 531311, Residential Property Managers), NAICS 531110 businesses are the direct owners and lessors of the residential real estate they lease.

Scope and Definition: What’s Included (and Excluded)?#

To avoid confusion, it’s critical to clarify what is and is not covered under NAICS 531110.

Included Activities#

• Rental of residential buildings: This includes apartments (low-rise, mid-rise, high-rise), single-family homes, townhouses, duplexes, and triplexes.
• Leasing of manufactured homes: If a business owns manufactured homes and leases them to tenants (e.g., a company that rents out mobile homes in a park), this falls under 531110.
• Short-term and long-term rentals: Both short-term (e.g., month-to-month leases) and long-term (e.g., 12-month leases) residential rentals are included.
• Ancillary services: Basic property maintenance (e.g., repairs, landscaping) and tenant screening are part of the core operations for these businesses.

Excluded Activities#

• Property management without ownership: Companies that manage rentals for third-party owners (but do not own the properties) are classified under NAICS 531311 (Residential Property Managers).
• Hotels, motels, and inns: These are temporary lodging and fall under NAICS 721110 (Hotels and Motels).
• Manufactured home dealers: Businesses that sell (not lease) manufactured homes are classified under NAICS 453930 (Manufactured (Mobile) Home Dealers).
• Student dormitories owned by educational institutions: These are part of NAICS 611310 (Colleges, Universities, and Professional Schools).
• Senior living communities with healthcare services: Facilities that combine housing with medical care (e.g., nursing homes) are classified under NAICS 623311 (Continuing Care Retirement Communities).

Key Activities of NAICS 531110 Businesses#

Businesses in NAICS 531110 engage in a range of activities to operate and maintain their residential rental properties. These include:

• Property Acquisition and Ownership: Purchasing or developing residential real estate (e.g., building an apartment complex or buying a portfolio of single-family homes).
• Tenant Screening and Selection: Conducting background checks, credit checks, and reference verifications to ensure reliable tenants.
• Lease Agreements: Drafting and enforcing rental contracts that outline terms (rent amount, lease duration, pet policies, etc.).
• Rent Collection: Managing monthly rent payments, including late fees and payment reminders.
• Property Maintenance: Handling repairs (plumbing, electrical, HVAC), landscaping, and general upkeep to keep units habitable.
• Marketing and Vacancy Management: Advertising vacant units (via online platforms, signage, or real estate agents) to minimize downtime between tenants.
• Compliance: Ensuring properties meet local building codes, safety standards, and fair housing laws.

Types of Establishments in NAICS 531110#

NAICS 531110 encompasses a diverse range of businesses, from small local landlords to large national corporations. Here are the most common types:

1. Apartment Complexes#

These are multi-unit residential buildings (e.g., 5+ units) owned by individuals, partnerships, or companies. Examples include mid-rise buildings in urban areas or garden-style apartments in suburbs.

2. Single-Family Rental (SFR) Companies#

Businesses that own and rent out single-family homes, often as part of large portfolios. In recent years, institutional investors (e.g., private equity firms) have expanded into this space, acquiring thousands of homes to lease.

3. Small-Scale “Mom-and-Pop” Landlords#

Individuals or small businesses that own a handful of residential properties (e.g., a duplex, triplex, or a few single-family homes). These landlords often manage properties themselves.

4. Student Housing Providers#

Companies that own and lease housing specifically for students (e.g., off-campus apartments near universities). These may include amenities like study rooms or shuttle services.

5. Manufactured Home Lessors#

Businesses that lease manufactured homes (mobile homes) to tenants, often in designated communities. Some also lease the land on which the homes sit (though land leasing alone may fall under a different NAICS code).

Current Market Trends Shaping the Industry#

The residential rental market is dynamic, influenced by economic, demographic, and technological shifts. After a period of rapid rent growth during the pandemic, the market has softened in 2025–2026, with vacancy rates rising to 7.3 percent in early 2026 and rent growth hovering near zero, according to the Harvard Joint Center for Housing Studies. Here are the top trends impacting NAICS 531110:

1. Shifting Rental Demand#

With homeownership costs (mortgages, down payments) increasing, more households have turned to renting. The U.S. Census Bureau reports that approximately 46 million households rented their homes in 2025. However, demand softened in late 2025 due to weaker job markets and economic uncertainty, with apartment household growth falling from 784,000 in mid-2025 to 366,000 by year’s end, according to the Harvard Joint Center for Housing Studies.

2. Growth of Build-to-Rent (BTR) Communities#

Developers are increasingly building new single-family and townhouse communities specifically for renters. As of 2026, more than 64,000 BTR homes are under construction nationwide, with an additional 139,000 units in planning stages, according to Matthews Real Estate Investment Services. These BTR properties appeal to families seeking more space than apartments, with amenities like playgrounds and fitness centers. The sector is consolidating under a smaller number of large operators as the market matures.

3. Tech Adoption#

Landlords are using property management software (e.g., AppFolio, Buildium) to streamline tasks: online rent payments, maintenance requests, and tenant communication. Smart home features (e.g., keyless entry, thermostats) are also becoming common to attract tech-savvy tenants.

4. Focus on Affordability#

Affordable housing shortages remain acute. In 2024, a record 22.7 million renter households (49 percent) were cost-burdened, spending more than 30 percent of income on rent and utilities, according to the Harvard Joint Center for Housing Studies. Some governments offer tax incentives to developers who include affordable units in their projects, and the 2025 federal reconciliation bill permanently increased Low-Income Housing Tax Credit allocations by 12 percent.

5. Remote Work Impact#

Remote and hybrid work arrangements have shifted rental preferences: tenants continue seeking larger units (for home offices) and moving to suburban or rural areas with lower rents, reducing demand in some expensive urban cores. This trend has persisted beyond the pandemic, influencing where new rental supply is being delivered.

Challenges Facing Residential Building Lessors#

While the residential rental market remains substantial, it also faces significant challenges:

1. Regulatory Changes#

Rent control ordinances (e.g., in cities like New York, San Francisco, and Portland) limit how much landlords can increase rents, squeezing profit margins. Fair housing laws (e.g., the U.S. Fair Housing Act) also require strict adherence to anti-discrimination practices, increasing compliance costs.

2. Rising Operating Costs#

Inflation has driven up expenses for maintenance, repairs, property taxes, and insurance. The cost of building materials surged during 2021–2022 and remains elevated, making renovations and new construction more expensive. Rising insurance premiums have been a particular challenge in states prone to natural disasters.

3. Tenant Turnover#

High turnover rates (common in student housing or urban areas) lead to lost rental income during vacancies and costs for cleaning, repairs, and re-marketing units.

4. Economic Uncertainty#

Recessions or job losses can lead to higher vacancy rates and late rent payments, putting pressure on landlords’ cash flow.

5. Competition#

In hot markets, landlords must compete for tenants by offering lower rents, better amenities, or flexible lease terms, which can reduce profitability.

Regulatory Landscape for NAICS 531110#

Compliance is critical for NAICS 531110 businesses, as they are subject to federal, state, and local regulations. Key laws include:

• Fair Housing Act (FHA): Prohibits discrimination based on race, color, religion, sex, national origin, disability, or familial status in housing transactions, including rentals.
• Local Rent Control Laws: Hundreds of U.S. cities and counties have some form of rent stabilization or control, limiting annual rent increases. California’s Tenant Protection Act (AB 1482), which caps increases at 5% plus the local consumer price index (or 10%, whichever is lower), is set to expire in mid-2026 unless renewed by the state legislature.
• Habitability Standards: Landlords must maintain units in a safe, livable condition (e.g., working plumbing, heat, and no mold). Violations can lead to fines or tenant lawsuits.
• Eviction Laws: Rules for evicting tenants vary by state, with some requiring extensive notice periods or mediation (e.g., New York’s “Right to Counsel” law provides free legal aid to tenants facing eviction).
• Tax Regulations: Landlords can deduct expenses like mortgage interest, property taxes, and repairs, but must report rental income to the IRS.

How to Use NAICS 531110: Practical Applications#

NAICS codes are not just for classification—they have real-world uses:

• Business Registration: When registering a business, you’ll need to select your NAICS code to determine tax rates, licensing requirements, and eligibility for government programs.
• Market Research: Investors and analysts use NAICS 531110 to study industry trends, size, and growth potential (e.g., via data from the U.S. Census Bureau or IBISWorld).
• Government Contracts: Small businesses in NAICS 531110 may qualify for federal contracting opportunities set aside for specific industries.
• Insurance and Lending: Lenders and insurers use NAICS codes to assess risk and set rates for rental property loans or insurance policies.

Conclusion#

NAICS 531110—Lessors of Residential Buildings and Dwellings—is a cornerstone of the housing market, providing homes to millions while driving economic activity. From small landlords to large institutional investors, businesses in this industry navigate evolving trends (tech adoption, remote work, BTR growth) and challenges (regulations, inflation, affordability pressures) to meet tenant demand. As of 2026, the market is adjusting to slowing demand, rising vacancy rates, and cooling multifamily construction. Whether you’re a tenant looking to understand your landlord’s operations or an investor exploring the rental market, a clear grasp of NAICS 531110 is essential. As the industry continues to adapt, staying informed about its dynamics will be key to success.
