Custer, SD Short-Term Rental Rules: What Hosted Permits Require

Needles Highway granite and pines in Custer State Park, no people

If you're sitting on a house near the Needles Highway or a spare bedroom a few blocks off Mt. Rushmore Road, June and July are when the math finally makes sense. Custer fills up fast in the summer, and every host in town has watched a neighbor's driveway go from empty to full of out-of-state plates almost overnight. But before you list a room or a whole house for the season, it's worth sitting down with the actual municipal code instead of guessing from what a friend down the street told you they did five years ago.

Custer's short-term rental rules live in Title 17 of the municipal code, and they draw a hard line between two very different animals: a hosted rental, where you're living in the house while a guest stays under your roof, and an unhosted rental, where the whole property is handed over with nobody home. The city treats those two situations differently depending on which zoning district your parcel sits in, and getting that distinction wrong is the single most common way hosts in Custer end up with a code enforcement letter instead of a booking calendar.

This guide walks through what the code says, section by section, what the city's 2026 fee schedule actually charges, what the sales and lodging tax stack looks like once a reservation posts, and where there are still real open questions worth a phone call to City Planning before you commit. None of this is a substitute for reading the ordinance yourself or talking to the city directly, and this is not legal advice.

Hosted vs. Unhosted: The Definition That Decides Everything

Everything in Custer's short-term rental rules flows from one definition in municipal code section 17.12.020. A hosted short-term rental is one where the owner is physically present on the property during the nights any portion of it is rented out, and a short-term rental itself is defined as anything under 30 consecutive calendar days. So the clock that matters isn't a weekend versus a week; it's whether you cross the 30-day line, and whether you're home while guests are staying.

That word 'hosted' is doing a lot of work in this code. It doesn't mean you're friendly and responsive by text. It means you, the owner, are sleeping on the property the same nights a guest is renting a room, a basement, an accessory space, or another portion of your home. If you're renting the entire house while you're away for the weekend, that's not a hosted rental under 17.12.020, and it changes which zoning rules apply to you.

Before you build a listing description or a pricing calendar, figure out honestly which category you fall into. A lot of the frustration hosts run into with any city's short-term rental code comes from assuming their situation is hosted because they live in Custer generally, when the ordinance is asking a narrower question: are you present on this specific property on the specific nights a guest is there.

Where You Can Actually Operate: Zoning by District

Zoning is where the hosted/unhosted distinction gets teeth. In residential districts, section 17.12.060.C prohibits boarding houses and any short-term rental that doesn't meet both the hosted definition in 17.12.020 and the specific standards laid out in 17.12.080. In plain terms, a residentially zoned property in Custer cannot run an unhosted short-term rental at all. The only path to renting in a residential district is the hosted path, and even that path has its own conditions layered on top.

Hosted short-term rentals are treated as a permitted conditional use in residential districts under section 17.12.050.M. That word 'conditional' matters just as much as 'permitted' — it means the use is allowed, but only when the conditions attached to it are actually met, and those conditions are the ones spelled out in 17.12.080, which we'll get into next.

If your property sits in the Central Business district or the Highway Commercial district, the picture changes. Sections 17.16.020.L and 17.20.020.L list short-term rentals right alongside hotels and motels as permitted principal uses in those two districts. That means Custer is not running a blanket citywide ban on unhosted rentals — commercial-zoned parcels have a much more straightforward path than residential ones. The takeaway for any host evaluating a property: pull up the parcel's actual zoning designation before you assume you know which rules apply. A house two blocks apart from another can land in completely different columns depending on the zoning line.

The Details Inside 17.12.080: Owner-Occupancy, the 80 Percent Cap, and ADUs

Section 17.12.080, adopted as Ordinance 922 in 2024, is where the hosted short-term rental conditions actually live, and it's worth reading slowly because several of its provisions will directly shape how you can use your property. First, the principal structure has to be the owner's primary residence — this isn't a rule you can satisfy with a second home you visit occasionally. Second, the owner has to be present on the nights the property is rented, echoing and reinforcing the 17.12.020 definition.

Third, and this is a detail a lot of hosts miss when they're mentally carving up their square footage: no more than 80 percent of the habitable area of the principal structure can be devoted to the short-term rental use. If you're renting most of the house and keeping one small room for yourself, run the math on habitable square footage before you list, because that 80 percent ceiling is a hard number in the ordinance, not a guideline.

Fourth, the code caps it at one hosted short-term rental per parcel. You can't split a single lot into multiple separately-listed hosted units and stack the income. And fifth, accessory dwelling units are explicitly excluded from being used as hosted short-term rentals — 17.12.080 says ADUs may not be used this way, and section 17.34.040.N separately bars ADUs from short-term rental use as well. If your plan involves renting out a detached guest cottage, carriage house, or converted garage apartment as your short-term rental while you live in the main house, that's the one configuration Custer's code closes off entirely, regardless of how the hosted/owner-occupancy math would otherwise work out.

Parking Requirements Hosts Tend to Overlook

It's easy to spend all your planning energy on occupancy percentages and zoning districts and forget that Custer's code also has something to say about where your guests park. Section 17.12.090.G.3 requires off-street parking for hosted short-term rentals. That means a guest's car in the street, even on a quiet residential block, doesn't satisfy the requirement — you need an actual off-street space or spaces available.

This one is worth thinking through before your first summer booking, not after a neighbor calls it in. If your driveway comfortably fits one car and you're advertising a listing that sleeps six with two vehicles expected, you've got a mismatch between what your listing implies and what the code requires you to provide. Walk your own property with fresh eyes and count actual off-street spaces, the way an inspector would, rather than assuming 'there's room on the street' will hold up.

The $300 Fee, and the One Question Still Worth Confirming

Custer adopted a new fee schedule on December 15, 2025, effective January 1, 2026, and it lists a permitted conditional use fee of $300. Since hosted short-term rentals are classified as a permitted conditional use under 17.12.050.M, that $300 figure is the number to budget for the application. There is no separate, dedicated short-term rental license line item in the current fee schedule — don't confuse this with the $300 special transient peddler fee that shows up elsewhere on the same schedule, which is a different category entirely and not what applies to a hosted rental application.

Here's the honest ambiguity, and it's worth naming rather than smoothing over: section 17.12.050.M frames hosted short-term rentals as a conditional use requiring that process, while 17.12.080 states the use 'shall be permitted' when its conditions are met, which reads more like a permitted-by-right standard once you satisfy the checklist. Those two sections don't obviously point to the same fee treatment, and it's genuinely unclear from the text alone whether every new hosted short-term rental still has to go through and pay for the full conditional use process, or whether meeting 17.12.080's conditions is meant to streamline that. The responsible move here is to call City Planning directly and ask which process applies to your specific parcel before you assume the $300 conditional use fee is either mandatory or optional for you.

You may also come across older press coverage from around 2022 referencing grandfathered conditional use permits from an earlier version of the ordinance. That coverage predates the current 17.12.080 text adopted in 2024, and it should not be read as a promise that permits are transferable between owners or that older approvals automatically carry forward under today's rules. Treat it as historical context, not current guidance.

Doing the Tax Math: What You Actually Collect and Remit

Once you're cleared to operate, the next practical question is what to charge on top of your nightly rate. Inside Custer city limits, a transient lodging stay under 28 days stacks four separate taxes: the state sales tax at 4.2 percent, the municipal sales tax at 2.00 percent (Department of Revenue code 088-2), the municipal gross receipts tax at 1.00 percent (code 088-1, per Custer municipal code 3.08.010), and the state tourism tax at 1.5 percent under SDCL 10-45D. Add those together and you land at 8.7 percent total on top of your rate for any guest staying inside city limits for less than 28 days.

If your property sits in unincorporated Custer County rather than inside the city limits, the stack is shorter: just the 4.2 percent state sales tax and the 1.5 percent state tourism tax, for a combined 5.7 percent. That's a real difference in what a guest pays and what you need to remit, and it's one more reason confirming your parcel's actual location — inside city limits or in the unincorporated county — matters as much as confirming its zoning district.

One more wrinkle worth knowing about: per the Department of Revenue's own hotels fact sheet, if the same guest stays 28 or more consecutive days, that stay becomes exempt from these transient lodging taxes entirely. If you're building a listing strategy around longer stays — say, a traveling nurse or a summer contractor booking a full month — that 28-day threshold is the number that flips your tax obligation off, and it's worth building into how you structure minimum-stay pricing for extended bookings.

City Limits vs. the County: Why the Line on the Map Still Matters

All of the Title 17 zoning rules we've walked through — the hosted definition, the residential district restrictions, the 80 percent cap, the conditional use fee — apply within Custer's corporate city limits. Custer County's own planning FAQ states plainly that the county currently has no zoning or building codes of its own. That does not mean unincorporated county land is a free-for-all with no permitting at all; the county still issues permits for things like driveway approaches, wastewater systems, and building work. It simply means the county hasn't adopted a short-term rental ordinance the way the city has.

This is a distinction hosts get wrong in both directions. Some assume that because a property has a Custer mailing address, Title 17 automatically applies — it doesn't, if the parcel is actually outside the corporate limits. Others assume no zoning code in the county means no permits of any kind are needed — also wrong, since the county still runs its own permitting for infrastructure even without zoning. And a property being inside the city's extraterritorial jurisdiction for platting purposes is not the same thing as that property being subject to Title 17's short-term rental provisions; ETJ status governs how new lots get platted, not which STR ordinance applies. Before you plan around either the city's tax stack or the county's simpler one, confirm with the city or county assessor which side of the corporate limits your actual parcel sits on.

The State License Question Nobody Should Skip

Beyond the city's zoning code, there's a separate, statewide layer to be aware of: South Dakota's Department of Health lodging license requirements can apply to a 'vacation home,' defined as a property rented in its entirety for more than 14 days in a year where it is not occupied by the owner or a manager. That definition is built around properties that sit empty of the owner while guests occupy the whole place.

Here's where hosts get themselves into trouble by pattern-matching too quickly: because you're running a hosted short-term rental where you're present every night guests are there, it's tempting to assume that automatically exempts you from any state lodging license requirement. Don't make that leap. The hosted, owner-present nights described in Custer's municipal code do not cleanly match the DOH's 'vacation home' definition, which centers on the property being unoccupied by the owner — but that mismatch doesn't automatically resolve the question either way, and it deserves an actual conversation with the Department of Health rather than an assumption made from your kitchen table. This is not legal advice, and a call to the DOH about your specific setup is worth the twenty minutes it takes.

Your Practical Next Steps Before You List

Pulling all of this together, here's the order that makes sense for a Custer host getting ready for summer bookings. First, confirm whether your parcel sits inside city limits or in unincorporated Custer County — that single fact determines whether Title 17 zoning applies to you at all, and which tax stack you'll be collecting. Second, confirm your zoning district, since residential, Central Business, and Highway Commercial parcels are governed by different sections of the code entirely.

Third, if you're in a residential district, work through the 17.12.080 checklist line by line: is this your primary residence, will you be present the nights you rent, does the rented portion stay under 80 percent of habitable area, is this your only hosted rental on the parcel, and does your setup avoid using an ADU as the rental unit. Fourth, call City Planning directly and ask, in plain terms, whether your specific application requires the $300 conditional use process under current practice, given the tension between 17.12.050.M and 17.12.080 — don't guess on this one. Fifth, walk your property and count actual off-street parking spaces against what your listing will advertise. And sixth, call the Department of Health about the vacation home lodging license question if there's any doubt about how your hosted setup is classified.

None of these steps require a lawyer to complete, but a few of them absolutely require a phone call to the city or the state rather than a guess based on what worked for a friend's property or what an old news article described. Custer's summer booking season doesn't wait for paperwork, so the hosts who start these calls in the spring are the ones with a compliant listing live by the time the Needles Highway traffic picks up in June.

Frequently Asked Questions

What's the difference between a hosted and unhosted short-term rental in Custer?

A hosted short-term rental, defined in municipal code 17.12.020, requires the owner to be physically present on the property during the nights any portion is rented, with stays under 30 consecutive days. An unhosted rental means the whole property is turned over with no owner present. Residential districts in Custer only allow the hosted path; unhosted rentals are limited to Central Business and Highway Commercial zoning under 17.16.020.L and 17.20.020.L.

Can I rent out my whole house in a residential neighborhood in Custer?

Only if you meet the hosted definition, meaning you're present on the property the nights it's rented, and even then no more than 80 percent of the habitable area of your principal structure can be devoted to the rental under 17.12.080. Renting the entire house while you're away doesn't qualify as hosted in a residential district, since 17.12.060.C prohibits unhosted short-term rentals there.

Can I use my accessory dwelling unit as a short-term rental?

No. Section 17.12.080 explicitly excludes ADUs from being used as hosted short-term rentals, and section 17.34.040.N separately reinforces that ADUs cannot be used as short-term rentals at all. If your plan depends on renting a detached guest house or garage apartment while you live in the main home, that specific configuration isn't allowed under current code regardless of how the rest of your setup meets the hosted requirements.

How much does a short-term rental permit cost in Custer?

The city's 2026 fee schedule, adopted December 15, 2025 and effective January 1, 2026, lists a permitted conditional use fee of $300, which is the applicable line item since hosted short-term rentals are classified under 17.12.050.M. There's no separate dedicated short-term rental license fee, and this should not be confused with the $300 special transient peddler fee listed elsewhere on the same schedule.

Do I definitely need to pay the $300 conditional use fee for a hosted rental?

This is genuinely unresolved from the text alone. Section 17.12.050.M frames hosted rentals as a conditional use, while 17.12.080 says the use 'shall be permitted' once conditions are met, which reads more like permitted-by-right. Because those two sections don't obviously agree on process, confirm directly with City Planning whether your specific application still requires the full conditional use fee before you budget around it.

What taxes do I need to collect on bookings inside Custer city limits?

Inside city limits, a stay under 28 days stacks four taxes: 4.2 percent state sales tax, 2.00 percent municipal sales tax (DOR code 088-2), 1.00 percent municipal gross receipts tax (code 088-1, per CMC 3.08.010), and 1.5 percent state tourism tax under SDCL 10-45D, totaling 8.7 percent. This is separate from any conditional use fee and applies to every qualifying short-term stay you book.

Is the tax rate different if my property is in unincorporated Custer County?

Yes. Properties in unincorporated Custer County only owe the 4.2 percent state sales tax and the 1.5 percent state tourism tax, totaling 5.7 percent, since the municipal sales tax and municipal gross receipts tax only apply inside city limits. Confirming whether your parcel is inside or outside the corporate limits is essential before you set your tax collection rate.

Does Custer County have its own zoning rules for short-term rentals?

According to the county's own planning FAQ, Custer County currently has no zoning or building codes of its own, so Title 17's short-term rental zoning rules don't extend into unincorporated areas. The county still issues permits for things like driveway approaches, wastewater systems, and building work, so the absence of zoning doesn't mean there's no permitting process at all for county properties.

Do I need a state Department of Health lodging license for my hosted rental?

It depends, and it isn't automatic either way. The DOH's vacation home license applies to properties rented in their entirety for more than 14 days a year without the owner or a manager present, which doesn't cleanly match a hosted setup where you're there every rented night — but that mismatch alone doesn't guarantee an exemption. Call the Department of Health about your specific situation, since this is not legal advice.

Does my hosted rental need off-street parking?

Yes. Section 17.12.090.G.3 requires off-street parking for hosted short-term rentals in Custer, meaning street parking for guests isn't sufficient to meet code. Before finalizing your listing's maximum guest count, walk your property and confirm you have enough actual off-street spaces to match how many vehicles your advertised occupancy is likely to bring during a busy summer weekend.

Can I run more than one short-term rental on my property?

No. Section 17.12.080 limits hosted short-term rentals to one per parcel, so you can't divide a single lot into multiple separately-listed rental units to stack income streams. If you're considering splitting a property into two rentable spaces, both would need to fall under the same single hosted listing rather than being marketed and booked as separate units.

I read that older Custer permits were grandfathered — does that apply to me?

Coverage from around 2022 referenced grandfathered conditional use permits under an earlier version of the ordinance, but that predates the current 17.12.080 text adopted via Ordinance 922 in 2024. Don't assume permits transfer between owners or that older approvals automatically carry forward under today's rules; confirm the status of any existing permit directly with City Planning rather than relying on older news coverage.
