A Santa Fe mailing address does not necessarily mean a property is inside city limits. Buyers can get excited about a home’s short-term rental potential only to discover that they were looking at the wrong set of rules.
Before estimating rental income, the first question is simple:
Is the property in the City of Santa Fe or in unincorporated Santa Fe County?
I have covered the City of Santa Fe’s short-term rental rules in a separate guide. This article focuses on Santa Fe County, where the application process depends on how you plan to use the property and where it is located.
Owner-Occupied or Non-Owner-Occupied?
Santa Fe County treats rentals of fewer than 30 consecutive days as short-term rentals.
An owner-occupied short-term rental is generally the owner’s primary residence—or an accessory dwelling unit, such as a casita, on the same legal lot as that residence. The County’s current application materials define the primary residence as one occupied by the owner for at least 275 days per year.
A non-owner-occupied short-term rental is a dwelling that is not owner-occupied.
The distinction affects the paperwork. Owner-occupied short-term rentals use a County business registration, while non-owner-occupied rentals require a business license.
If the property will be a true second home rather than your primary residence, it will generally fall into the non-owner-occupied category. If you plan to live on the property and rent a casita, the owner-occupied rules may apply.
Because the details of the property and your intended use matter, confirm the specific setup with County staff before relying on rental income.
Are There Limits on County Rentals?
Yes.
Santa Fe County allows a maximum of two short-term rental registrations or licenses per owner, and each residence needs its own registration or license—even when two residences are located on the same property.
The County also limits non-owner-occupied short-term rentals in certain Census Designated Places. Depending on the area, the limit may be either 3% or 7% of homes. If an area has reached its limit, an applicant may be placed on a waiting list.
Owner-occupied short-term rentals are not subject to those particular area limits.
This is an important difference between the City and County systems. The City has a citywide cap on residential permits, while County availability for non-owner-occupied rentals can depend on the particular area where the property sits.
A neighboring property’s rental license does not establish that another application will be available when you buy.
If a property is already operating as a short-term rental, do not assume its existing approval automatically carries over to a new owner. Ask County staff what a change of ownership would require for that specific property before counting on continued rental use.
Can That Casita Legally Be Rented?
A charming casita can be a real selling point in Santa Fe, but buyers should look beyond how the space is described in an advertisement.
Santa Fe County requires a dwelling used as a short-term rental to be legally constructed and permitted, and the property must also be a legal lot of record.
An unpermitted garage conversion, studio, casita, or other dwelling may require after-the-fact permitting, a plat, a variance, or another form of County approval before it can qualify for full short-term rental approval.
The County’s application process may also call for items such as:
- an approved survey plat;
- proof that property taxes are current;
- an assigned address;
- a fire self-certification form;
- a site plan;
- and a floor plan.
The site plan identifies features such as structures, access, designated parking, and trash storage. The County allows these plans to be hand-drawn; what matters is that they accurately represent the property and proposed rental space.
If rental use is important to your purchase, make time during due diligence to confirm a casita or converted space’s permit history and discuss the property directly with the County.
That conversation can tell you much more than a listing description can.
What Responsibilities Come With Operating a County Rental?
Approval is only part of the picture.
County operators must notify adjacent neighbors and any applicable homeowners association. That notice includes a 24-hour contact person who can respond if there is a disturbance.
Operators must also post the County’s notice to renters inside the property.
Occupancy is generally limited to two people per approved bedroom, up to ten adults, with children under five excluded from that count.
That means the number of approved bedrooms and the property’s parking setup are practical questions worth investigating before you buy.
There are also tax and reporting responsibilities.
Short-term rental income in Santa Fe County may be subject to New Mexico gross receipts tax and County lodgers’ tax. County lodgers’ tax reporting follows a monthly schedule, and hosts using third-party booking platforms may still have County reporting responsibilities even when the platform remits tax on their behalf.
If rental income is important to your financial plan, include these obligations alongside management, insurance, maintenance, utilities, and periods when the property may be vacant.
A Few Questions to Ask Before Making an Offer
If short-term rental income is part of your buying decision, I would start here:
- Which jurisdiction governs the property?
Confirm whether it is inside City limits or in unincorporated Santa Fe County. - Which County category fits your plans?
Will the rental be owner-occupied or non-owner-occupied? - Is there capacity for a non-owner-occupied rental in that area?
Ask County staff about the specific address. - Is the dwelling legally permitted?
This is especially important for casitas, converted spaces, and properties with multiple residences. - Does an HOA have its own restrictions?
Review association documents separately from County requirements. - What happens if the property already operates as an STR?
Confirm what a new owner would need to do rather than assuming an existing registration or license transfers. - Do the expected numbers still work?
Include licensing, taxes, insurance, management, maintenance, utilities, and realistic vacancy—not just the nightly rate shown online.
The County accepts short-term rental applications by appointment. Its current short-term rental staff can be reached at 505-995-2700 or str@santafecountynm.gov.
I love helping buyers see the possibilities in a Santa Fe property, especially one with a casita or a layout that offers flexibility. But if rental income is central to the purchase, it deserves careful homework before closing.
Knowing which rules apply to the specific property gives you a much clearer picture before you make that decision.
