The 'Rocket Man' hitmaker and his husband have sold adjoining condos at West Hollywood's Sierra Tower for $4.65 million because of concerns about 21-month-old Zachary's safety due to the abode being ''dangerously high up''.
A source told RadarOnline.com: ''The reason behind Elton and David giving up their West Hollywood condos is because they thought it wasn't a suitable place for a toddler to grow up in.
''They did love the home, but now they are parents they have to think more sensibly and it wasn't ideal for Zachary.
''The apartment was situated halfway up the Sierra Towers complex, so it was dangerously high up.''
The passing of Eric Clapton's four-year-old son Conor - who plunged 49 storeys to his death in 1991 after falling out of an open window - is also said to have heavily influenced Elton and David's decision to sell the condos, which were in David's name and on the market since March.
The source added: ''Despite all the constant attention they give Zachary, Elton and David feared that the toddler could climb out of one of the apartment's many windows and fall.
''Zachary is very precious to them, and Elton remembered what happened to his close friend Eric Clapton who lost his son Conor in such a tragic way.
''They thought about installing window guards all throughout but Elton was terrified that one of them could malfunction or break, and he couldn't live with that on his conscience.''
The pair have since splashed out on a $7.65 million child-friendly home in Beverly Hills, which boasts three bedrooms, 3.5 bathrooms, a staff bedroom and bathroom, pool, a gym, floor-to-ceiling windows and white-oak flooring.
