Homes with Casitas & Guest Houses in Highland, Utah
Highland sits at the base of the Wasatch Range along the Alpine Highway corridor, and its larger lots — many a third of an acre or more in neighborhoods like Highland Glen and the areas off 6800 West — make room for casitas and detached guest houses in a way that tighter-lot cities like Lehi or Saratoga Springs often can't match. A lot of these properties started as custom builds where the owner added a detached mother-in-law setup, a converted garage apartment, or a full guest house with its own kitchen and entrance. In Utah County, where multigenerational living is common and college kids at UVU or BYU need a place to land, that separate structure solves a real problem instead of just adding square footage.
Buyers here are usually looking for one of three things: space for aging parents, a rentable unit to offset the mortgage, or a private setup for adult kids who aren't quite ready to leave. Highland's zoning varies by subdivision, so whether a casita can legally be rented out long-term depends on the parcel — something worth confirming with the city before writing an offer. Prices for homes with a legitimate detached guest house tend to run well above Highland's typical range, given the extra square footage and lot size required to support one.

Common questions
About homes with casitas & guest houses in Highland.
Does Highland City allow casitas and detached guest houses? ▾
Yes, but detached accessory dwellings are tied to lot size and zoning — most legal casitas sit on R-1-40 (roughly one-acre) parcels with specific setback requirements. Internal ADUs are allowed more broadly. Always pull the permit history with Highland City before closing, since some guest houses were built as unpermitted additions.
Can I rent out a guest house in Highland on Airbnb? ▾
Short-term rentals are heavily restricted in Highland and most detached ADUs are approved only for family use, not nightly rentals. Long-term rentals may be allowed with owner-occupancy of the main home. Confirm current rules directly with Highland City Planning before counting on rental income.
What's the price premium for a Highland home with a casita? ▾
Expect roughly $80,000 to $150,000 over a comparable home without one, though high-end finishes, full kitchens, and separate utilities can push that higher. Homes in the $1.2M–$2M range on larger Highland Oaks lots are where most permitted guest houses show up.
Are these typically attached mother-in-law suites or fully detached buildings? ▾
Both exist on the Highland MLS. Attached suites with private entrances are more common in newer builds from the 2010s onward, while fully detached casitas tend to appear on the older acre lots closer to the Lone Peak foothills. Listing photos and floor plans usually make the distinction clear.
Do guest houses in Highland have separate utilities? ▾
It varies. Many older detached units share water and gas with the main home, while newer permitted builds often have separate electrical sub-panels and sometimes their own gas meter. Separate utilities matter if you plan to rent long-term or want clean accounting for a home office.
Why are casitas more common in Highland than nearby cities? ▾
Highland's larger minimum lot sizes — particularly in the R-1-40 zone east of the freeway — leave room for a second structure without crowding the property. Cities like Pleasant Grove and Lehi have far more quarter-acre lots where a detached casita just won't fit within setbacks.
