Parab obtained "illegal" permission from the state revenue department for construction of a twin bungalow (ground+1 floor) over a piece of land falling under CRZ-III, the ED said.
Parab, a senior Shiv Sena leader, reached the ED's office at Ballard Estate in south Mumbai around 2:45 pm, and left around 9 pm.
He was summoned on Wednesday morning, but citing the political developments in the state, he had sought more time to appear before it.
The ED had summoned Parab for questioning in the money laundering probe linked to alleged violation of coastal regulation zone provisions in the construction of a resort in Ratnagiri.
The ED had raided his premises and those allegedly linked to him in May, after registering a fresh case under the PMLA against him and others.
The federal agency wants to question and record Parab's statement under the Prevention of Money Laundering Act (PMLA), they said.
At least seven premises, including Parab's official residence in Mumbai, linked premises in Dapoli and Pune were being searched by the agency with a security escort.
Sena workers gathered near the statue of Tara Rani in the city and raised slogans against the ED's action on party leader Parab, and put up a banner criticising the probe agency.
The ED had earlier arrested Maharashtra minister Nawab Malik and former state Home Minister Anil Desmukh in different money laundering cases.
