Households access public ERP through municipality/ATER allocation procedures and local notices; check the municipality where the household seeks housing for the current application window and ranking rules. A separate Lazio 2026 ATER-complex social-animation notice (G11697) closed 23 September 2026 and funded resident community activities, not housing acquisition or renovation. It is not a group capital scheme. Other social-housing calls found in the search were prior-year/closed; the reviewed sources do not establish a currently open regional capital grant for a cohousing group.
