This paper is devoted to studying the regularity properties for the new maximal operator
M
φ
{M_{\varphi}}
and the fractional new maximal operator
M
φ
,
β
{M_{\varphi,\beta}}
in the local case. Some new pointwise gradient estimates of
M
φ
,
Ω
{M_{\varphi,\Omega}}
and
M
φ
,
β
,
Ω
{M_{\varphi,\beta,\Omega}}
are given. Moreover, the boundedness of
M
φ
,
Ω
{M_{\varphi,\Omega}}
and
M
φ
,
β
,
Ω
{M_{\varphi,\beta,\Omega}}
on Sobolev space is established. As applications, we also obtain the bounds of the above operators on Sobolev space with zero boundary values.
