Rohini is served by Delhi Metro's Red Line (Rithala, Rohini East, Rohini West stations) and Yellow Line (Rohini Sector 18/19, Samaypur Badli), with interchange to the Green Line via Inderlok and Kashmere Gate. Road access includes National Highway-9, linking to Haryana, Punjab, Uttar Pradesh and Uttarakhand via NH 10, 24, 87, 74 and 125, plus the Outer Ring Road.

DTC buses and an approved Phase IV metro extension toward Narela further strengthen connectivity.

Rohini hosts the Delhi Technological University (DTU) along with the Jagan Institute of Management Studies and Delhi Institute of Advanced Studies.

School options include Delhi Public School, Ryan International School, Kendriya Vidyalaya, DAV Public School, Sachdeva School, Mount Abu Public School and Queen's Convent, giving residents a wide choice of CBSE schooling and higher-education options within the sub-city.

Rohini itself is predominantly residential, but it borders North West Delhi's manufacturing belt.

The Delhi government's Labour Department lists Mangolpuri (Phase I & II), Wazirpur, Narela, Bawana and Samaipur-Badli among NCT Delhi's approved industrial areas, all within or bordering the Rohini periphery, supporting engineering, plastics, packaging and consumer-goods units and offering employment close to home.

The sub-city's best-known attraction is Swarn Jayanti Park (Japanese Park) in Sector 11, a 96-hectare DDA park with Japanese, Mughal-style and sculpture gardens, boating lakes and picnic spots that draws large crowds, especially on holidays.

Adventure Island, an amusement and water park at the Metro Walk complex in Sector 10, is another major draw for visitors from across Delhi-NCR.

Rohini's retail and leisure scene centres on malls such as City Centre Rohini, Ambience Mall, Unity One Mall and Kings Mall, along with the open-air Metro Walk shopping and dining complex adjoining Adventure Island.

Multiplex cinemas including Cinepolis and other screens serve residents, while sector-wise local markets and Sunday bazaars add to everyday retail and eating-out options.

As DDA's first sub-city project, Rohini has planned road networks, district and neighbourhood parks, community and convenience shopping centres, and a DDA sports complex in Sector 14 with a swimming pool, cricket ground and multiple courts. The Rohini District Courts Complex, operational since 2006, houses courts serving Delhi's West and North West districts.

DDA continues upgrades to roads, drains and open spaces across the sub-city's sectors.
