Additional context
Admittedly, this is a matter of opinion, but I'm not sure if this was something that was considered when houses were made more common.

You can try lowering value of basement_hidden_lab_stairs:

Cataclysm-DDA/data/json/regional_map_settings.json

Line 537 in 4a1ab34

"basements": { "basement": 1000, "basement_hidden_lab_stairs": 50, "basement_bionic": 50 },

@Inglonias I've been doing some local testing with the value mentioned by ZhilkinSerg and when changing the value from 50 to 25 the results are much more reasonable.

I created a world with default settings (city size 8 and city spacing 4). I left the regional settings at default and checked 30 generated cities that contained at least 10 houses each. I found 33 basement labs in the 30 cities checked.

I created another world with the same settings but I changed regional settings for basement_hidden_lab_stairs to 25. I found 9 basement labs in the 30 cities checked.

Does that seem more acceptable?
