As the weather heats up, Mecklenburg County is cracking down on a fast-growing trend of renting pools online.

Why it matters: Listing pools on short-term rental apps like Swimply has become a source of income for homeowners and a fun option for families and groups looking to cool off in the summer.

• But Mecklenburg County says it's a safety issue, especially for children.

Driving the news: This week, the county's public health department warned residents that short-term rentals of home pools are forbidden.

• "Residential pools cannot be rented or offered for general public use," Chrystal Swinger, Mecklenburg County Public Health Environmental Health Division director, stated in a news release. "Only a properly permitted public pool can be rented to or used by the general public, and we inspect those pools every year."

Between the lines: North Carolina does not consider a home swimming pool as private once it's rented for money, the release explains.

• At that point, the state deems it a public pool and requires an operation permit and high standards to be met related to construction, injury prevention and other safety hazards.

Yes, but: Airbnbs, Vrbos and other short-term vacation rentals often advertise pools as amenities. Those pools aren't held to the same standard as county-regulated pools.

Local restaurants keep adding brunch menus to their lineups, responding to a growing demand for late-morning eggs and Bloody Marys.

• So many have expanded their brunch offerings, that we decided to strike non-North Carolina-based chains (like Snooze and First Watch) from our brunch guide.

Catalú, the tapas restaurant in the former Eight+Sand spot, is the latest place to start serving brunch on weekends.

What to expect: Like its dinner menu, Catalú's brunch offering features shareable plates from the Catalonia region of Spain, which includes Barcelona.

• In addition to new menu items — like tortilla Española and avocado toast — you'll find brunch iterations of dinner menu favorites.
• The steak and huevos, for instance, is the brunch version of the steak on Cabrales blue cheese sauce on the dinner menu.
