Bill and Hillary Clinton have been renovating a property that they purchased next to their Chappaqua, New York, home without first securing the necessary permits.

Building department records from Westchester County indicate that the former president and the current Democratic nominee back-filled an in-ground swimming pool and covered it with gravel, The Journal News reported on Friday.

The building department report by inspector William Maskiell of New Castle, New York – the township which has jurisdiction over Chappaqua – shows that a complaint was filed against the Clintons by an anonymous individual.

Maskiell learned upon inspecting the property at 33 Old House Lane earlier this month that the kitchen, floors, and walls were recently renovated and new electrical fixtures were being installed in the ceiling.

The home is right next to 15 Old House Lane, the address of the house that the Clintons officially moved to in 1999, just before Hillary Clinton launched her successful candidacy for one of New York's Senate seats.

The Clintons purchased the property at 33 Old House Lane this past August for $1.16million.

When Maskiell went to the home to follow up on the complaint, he told the contractor there that permits were required for the renovations that were undertaken.

'During conversation I was told that the owners wanted to have all work done and finished by Thanksgiving and were quite adamant about it and what had started as a paint job turned into this,' Maskiell's report read.

The Clintons moved into the home on 15 Old House Lane in 2000. It has been their official residence since Hillary's run for the Senate

The Journal News tried unsuccessfully to contact the Clintons for a response.

Maskiell said that the permits are usually requested by architects and contractors.

Failure to obtain necessary permits for extensive changes to the home like excavations and interior construction could result in fines, according to Maskiell.

'The homeowners have to sign the applications because it's their property,' Maskiell said. 'If you own the house, you're responsible on everything that goes on with that house.'

The Clintons snapped up the three-bedroom house next door to their home in the leafy New York suburb reportedly in a bid to create a secure compound for the whole family to stay.

The ranch-style house sits on 1.5 acres of land and will allow the former – and perhaps future – first couple to extend their current home.
