The municipality of Odivelas, Portugal, has implemented a new affordable housing program designed to limit rental costs for residents. The initiative establishes maximum rent values for various property types, ranging from 400 euros for studio apartments (T0) to 1,125 euros for five-bedroom homes (T5). A key component of the program is ensuring that housing costs do not exceed 35% of a tenant's income, referred to as the “effort rate”. This aims to increase housing accessibility for a wider range of income levels within the community. The scheme provides a structured and capped rental market, offering stability for renters and potentially addressing a growing need for affordable options. Authorities hope this program will mitigate rising housing costs and improve the quality of life for Odivelas residents.
