Homes with Casitas & Guest Houses in Holladay, Utah
Holladay sits in one of the most established pockets of the Salt Lake Valley, with mature trees, half-acre estate lots, and a quiet residential character that has drawn multigenerational families for decades. That history is exactly why secondary dwellings are more common here than in newer Utah suburbs — many original 1950s and 1960s estates along Walker Lane, Holladay Boulevard, and the streets climbing toward Mt. Olympus were built with detached guest quarters, pool houses, or staff cottages. Today those structures are pulling double duty as in-law suites for aging parents, work-from-home offices, returned-missionary apartments, or long-term rentals supplementing a steep Wasatch Front mortgage.
Casitas in newer Holladay construction tend to look different — attached suites above oversized garages, or main-level guest wings with a private entrance off a courtyard. Both types trade at a premium in this market because Holladay's R-1-43 and R-1-21 zoning limits how easily a buyer can add one after the fact, and Holladay City's ADU ordinance has specific rules about owner occupancy, parking, and short-term rental use. With Cottonwood Mall redevelopment, easy access to Big and Little Cottonwood canyons, and Holladay Village's walkable restaurants, demand for flexible multigenerational floor plans has stayed strong even as the broader Salt Lake market has cooled. Browse the active listings below to see which Holladay homes currently include a casita or guest house, and check the remarks carefully for permitting and kitchen details.

Common questions
About homes with casitas & guest houses in Holladay.
What's the difference between a casita and a guest house in Holladay listings? ▾
In Holladay MLS data, a casita usually refers to an attached or detached secondary suite without a full kitchen, while a guest house is a fully self-contained structure with its own kitchen, bath, and often a separate entrance. Holladay's older estate properties tend to have true detached guest houses, while newer builds in places like Cottonwood Heights-adjacent pockets lean toward attached casitas above garages.
Can I legally rent out a casita or guest house in Holladay? ▾
Holladay City allows internal accessory dwelling units by right in most residential zones, but detached ADUs and short-term rentals have stricter rules and may require a conditional use permit. If rental income matters to your purchase, verify the structure's permitted status with Holladay City Planning before writing an offer — many older guest houses predate current code and are grandfathered.
Which Holladay neighborhoods most often have homes with guest houses? ▾
The larger-lot areas along Walker Lane, Holladay Boulevard, and the streets east of Highland Drive toward Mt. Olympus tend to have the original mid-century estates with detached guest quarters or pool houses. Newer construction in the Cottonwood Club area and tear-down rebuilds increasingly include casitas as part of the floor plan.
What price range should I expect for a Holladay home with a casita? ▾
Most Holladay homes with a true second dwelling start around $1.4M and run well into the $3M+ range for estate properties on half-acre-plus lots. The casita itself typically adds $150K to $400K of value depending on size, finish level, and whether it's permitted as an ADU.
Are guest houses counted in the main home's square footage on the MLS? ▾
Usually no — detached guest house square footage is listed separately under outbuildings or accessory structures, and it doesn't count toward the main home's finished square feet. Always check the property's tax records and the listing remarks, because some agents bundle the numbers and some don't, which makes price-per-square-foot comparisons misleading.
Do casitas in Holladay typically have their own utilities? ▾
It varies. Older detached guest houses often share a single meter with the main residence, while newer permitted ADUs are required to have separately metered electric and sometimes gas. If you're planning to rent the unit or house an aging parent who pays their own way, ask the listing agent for utility setup details upfront.
