STR Rules

Owner-Occupied vs. Investor-Owned: What It Means for STR

The single most consequential STR regulation in many cities isn't a night cap or a permit fee — it's the owner-occupancy requirement. If you're considering an investment property for short-term rental use, understanding this distinction can determine whether your strategy is legal at all.

What Is an Owner-Occupancy Requirement?

An owner-occupancy requirement (also called a primary-residence requirement or hosted-only rule) means that only a property where the owner actually lives can be listed as a short-term rental. Investor-owned properties — homes or units purchased as pure investments — cannot be listed for STR regardless of the duration.

The policy rationale: cities with housing shortages use owner-occupancy requirements to prevent investors from converting long-term housing stock into de-facto hotels. The argument is that a homeowner renting out a room or their home while they're away does not remove housing from the market; an investor operating an unoccupied STR unit does.

Cities With Strict Owner-Occupancy Requirements

New York City

New York's Local Law 18 (effective September 2023) created one of the most restrictive STR regimes in the U.S.:

• Hosts must register with the Mayor's Office of Special Enforcement (OSE). Registration requires proof of primary residency.
• The host must be present during the guest's stay. Whole-apartment STRs are effectively banned.
• Maximum 2 guests at a time, must have free access to all rooms.
• Platforms (Airbnb, Vrbo) are prohibited from listing non-registered properties, with fines up to $5,000 per violation.

In practice, Local Law 18 has dramatically reduced NYC Airbnb listings — from approximately 22,000 active listings before the law to under 3,000 afterward in Manhattan alone.

Santa Monica, California

Santa Monica was an early mover on owner-occupancy STR requirements:

• Home-sharing (host present) is permitted with registration. Maximum 30 nights per calendar year per rental period.
• Vacation rentals (host absent) are prohibited entirely for periods under 31 days.
• Fines of $500/day per violation are actively enforced.
• The city has sued Airbnb and platforms for listing non-compliant properties.

San Francisco, California

• Host must occupy the property for at least 275 nights per year (establishing primary residency).
• Unhosted whole-apartment STRs capped at 90 nights per year.
• Multi-family buildings with 5+ units: STRs subject to additional building-level restrictions.

Los Angeles, California

• Primary residence requirement for all whole-home listings.
• "Type A" (unhosted) allows up to 120 nights per year if your primary residence.
• "Type B" (unhosted, above 120 nights) license issuance has been effectively suspended.
• RSO-covered units face near-total prohibition regardless of occupancy status.

Portland, Oregon

• Owner must occupy at least one unit of the property being listed.
• Maximum 2 guest rooms in the hosted unit.
• Accessory Dwelling Units (ADUs) may be listed separately from the main unit if the owner lives in the main structure.

Cities That Explicitly Allow Investor-Owned STRs

Many markets have no owner-occupancy requirement. These cities are more favorable for pure investment STR strategies:

• Palm Springs, CA — No primary residence requirement. Permit required; active enforcement of health/safety rules.
• Nashville, TN — Non-owner-occupied STRs permitted in non-residential and commercial zones. Residential zones have restrictions.
• Scottsdale / Phoenix, AZ — Arizona state law (SB 1350) preempts many local bans; investor-owned STRs broadly permitted with registration.
• Galveston, TX — Beach vacation rentals permitted citywide; no owner-occupancy requirement.
• Gulf Shores / Orange Beach, AL — Vacation rentals are a primary economic driver; broadly permitted.
• Gatlinburg / Pigeon Forge, TN — Cabin rental market; no primary residence requirement.

How to Verify Occupancy Status on a Property

County public records often indicate owner-occupancy status:

• Homestead exemption status: If the current owner has a homestead exemption on the property, it's (or was) their primary residence. No exemption often signals investor ownership.
• Owner mailing address: County assessor records include the owner's mailing address. If different from the property address, the owner doesn't live there.
• Voter registration: Public voter rolls sometimes reflect the owner's registered address.
• Rentcast and other data providers: Include an "ownerOccupied" field derived from public records. AbodeIQ surfaces this in the Property Details section for Premium users.

What This Means for Your Investment Strategy

If you're buying a property specifically for STR income:

1. Identify the city and county jurisdiction before purchase.
2. Check whether an owner-occupancy requirement exists.
3. Understand whether the requirement is enforced (some cities have rules on paper but no compliance mechanism).
4. Model the downside: if STRs are restricted after purchase, what does long-term rental cash flow look like?
5. Never rely on the current regulatory environment being permanent — STR rules are the most actively changing area of local real estate regulation.

STR regulations change rapidly. Verify current owner-occupancy requirements with the relevant city or county before purchasing or listing a property. This guide is for educational purposes only.
