The neighborhoods of San Isidro and Opañel, in Carabanchel, are adding 3,100 regulated parking spaces to the SER zone following a neighborhood referendum in which 74% of residents voted in favor. This is another step in the expansion of the regulated parking system toward the southern part of the city, through which the City Council aims to curb the “border effect” and ensure parking spaces for those living in these areas, which are increasingly burdened by through traffic.
San Isidro and Opañel are part of the Carabanchel district, one of Madrid’s major residential neighborhoods anda magnet for cars coming from outside the city to park for free near the M-30 and low-emission zones. The new Sustainable Mobility Ordinance already provided for these two neighborhoods to be included in the SER before December 31, 2029, as part of a first phase that also includes Peñagrande, Valdezarza, and Costillares.
Now, the City Council is moving forward with the plan in Carabanchel, where signage, road markings, and parking meters will be installed in the coming months. According to the documentation from the public consultation, the rollout will be phased to gradually adjust streets and green/blue zones to actual demand, but the goal is clear: before the end of the decade, the entire perimeter of these neighborhoods will be under SER control.
A change supported by residents
One of the City Council’s political arguments is that this expansion “is not being imposed from above,” but rather comesafter being requested on multiple occasions by neighborhood associations and ratified through Decide Madrid. In the specific consultation on the expansion of the SER in Carabanchel, the combined results for San Isidro (phase 2) and Opañel (phase 1) showed 74% support for regulating parking on these streets.
The reason lies in everyday life: since low-emission zones were implemented in the city center and parking meters were reinforced in neighboring districts, many drivers have begun using San Isidro and Opañel as free park-and-ride areas, saturating residents’ parking spaces. For those who live there, paid parking has become a lesser evil, since it does mean paying to park, yes, but in exchange it ensures turnover, limits long-staying non-resident cars, and improves the chances of finding a spot when arriving home.
What the new SER zone in San Isidro and Opañel will look like
Although the detailed plans are published on the municipal website, the model is the same as that applied in other neighborhoods that have recently been incorporated into the SER.
Key points:
- Green parking spaces for residents, where those with a resident card can park for extended periods by paying a reduced annual or monthly fee.
- Blue parking spaces for non-residents, with time limits (maximum 2–4 hours depending on the zone) and per-minute rates designed to encourage the rotation of passing cars.
- General SER hours: Monday through Friday from 9:00 a.m. to 9:00 p.m., and Saturdays (and some holidays) until 3:00 p.m., although the new ordinance opens the door to expanding the service to Sundays and evenings in specific areas, a move that could come later if pressure demands it.
In total, the expansion of the SER to 22 neighborhoods across seven districts (including Carabanchel and Usera) will add 66,120 new regulated parking spaces by 2035, a 36% increase over current levels. The 3,100 spaces in San Isidro and Opañel are just one piece of that puzzle, but a very significant one for the southern part of the city.
Although this specific expansion affects Carabanchel, the broader context also includes Usera: neighborhoods such as Moscardó, Almendrales, Pradolongo, Zofío, and Orcasur have been gradually incorporated into the SER over time to curb the border effect in the south. Zofío, for example, recently installed parking meters, and other areas of Usera have already seen how green zones have changed the way people park.
