Short-Term Rentals Around Crystal Lake: Two Townships, Two Ordinances

Lake Township: permits, inspections, and a hard cap since 2023

Lake Township, which includes a stretch of Crystal Lake shoreline, passed its short-term rental ordinance in September 2023, effective November 30 of that year. The program requires an actual permit and a property inspection before a rental can operate, and it caps how concentrated ownership can get: no single owner may hold more than two short-term rental permits within the township. The township also caps total participation at 75 annual licenses countywide within its borders -- a hard ceiling rather than an open-ended registration system. If you're evaluating a Lake Township property specifically to add to an existing short-term rental portfolio, the two-property-per-owner cap is worth checking before assuming a third property in the township could be licensed at all.

Crystal Lake Township: a newer ordinance, still phasing in

Crystal Lake Township passed its own, separate short-term rental ordinance on March 19, 2025, effective May 2, 2025 -- and it's being phased in deliberately rather than enforced at full strength immediately. The first year functions as a data-gathering period: the township collects information on the local short-term rental situation starting in spring 2025 without yet applying the ordinance's full enforcement measures, with full implementation targeted for fall 2025. As of September 15, 2025, the township had already made its 2026 license application packet available online, suggesting the phase-in was on track to reach full licensing requirements for the 2026 rental season. A buyer evaluating a Crystal Lake Township property today should confirm exactly which phase of implementation is currently active and what the 2026 licensing packet actually requires, since this ordinance is new enough that its practical effect was still settling in as of this research.

What to verify before counting on short-term rental income here

• Which township the specific parcel sits in -- Lake Township and Crystal Lake Township have separately-adopted, differently-timed ordinances even though both touch the same lake.
• In Lake Township, whether the current owner already holds a permit count near the two-per-owner cap, and whether the township's 75-annual-license ceiling has room.
• In Crystal Lake Township, the current phase of the ordinance's implementation and what the current-year license application packet requires.
• Whether the specific property has an existing short-term rental permit that could transfer, versus needing a new application under whichever cap or phase currently applies.
