ALBUQUERQUE, N.M. (KRQE) – Albuquerque has rules on the books requiring home heating, but a new change is also now requiring property owners to put in cooling systems. City Councilor Tammy Fiebelkorn said the bill is really aimed at making sure older buildings are retrofitted with cooling systems. "Cooling is a basic human necessity and I urge your support," Fiebelkorn said at the city council meeting early Tuesday morning.

Passed just after 1:00 am Tuesday, Fiebelkorn led the push to keep the city cool as the summers become hotter and longer. Up to this point, the Uniform Housing Code has only required Albuquerque homes to have heating. Fiebelkorn said this amendment makes sure older buildings get retrofitted to also make homes habitable in the summer. "New buildings are being built correctly, but we do have a lot of existing housing stock in our city, particularly multi-family units that maybe didn't already have that," Fiebelkorn said, "When these houses were built and when these apartment buildings were built back in the 50s, it wasn't as hot here. And so, there was no need for putting in cooling for every single building. But, with climate change, we've seen really hot, hot summers that stay hot longer and gets hotter later into the year." "So we need to go back in and retrofit those existing homes; but honestly, there are very few that haven't been retrofit[ted]. What we needed was a way to enforce that if you have cooling in your rental units and it breaks, you have a right as a tenant to have that fixed. And now, because this bill passed, you do have that right and the city can help us enforce that so that people aren't sitting there baking in their own homes," Fiebelkorn said. The proposal drew mixed reactions from the crowd; some argue that the costs of revamping older homes are too high for landlords and homeowners. "A lot of these rentals are owned by school teachers, single women, retired people that use that income to supplement their retirement. So, I ask you to consider those things and not do something that's going to cause an even more drastic shortage of affordable housing in our current market," said Jack Corder, who opposed the change. Others entreated the council to pass the change: "I live in a home that doesn't have heating or cooling and I'd like some A/C. So, I'm asking if I can have some. Please," said Thomas Abeyta who supported the change. "Extreme heat is not felt equally across communities. It disproportionately affects low-income people, people with chronic diseases, the disabled, elderly, children, and most especially renters," said Leila Salim who supported the change. The amendment passed narrowly on a five to four-vote. If the mayor signs it, it could go into effect within the next month. The new ordinance also states if a home does not have cooling, it will be considered 'inadequate sanitation' under the Uniform Housing Code—which could carry citations or fines worth hundreds of dollars.
