Searches for flavor changing neutral currents in production and decay of top quark pair and single top process using the data collected by the Compact Muon Solenoid (CMS) experiment at $\sqrt{s}$ = 13 TeV in 2016 is presented, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Final states with one isolated lepton and at least three jets including 2 b-tagged jets are selected. In both single top (pp$\rightarrow$tH) and $\mathrm{t\bar t}$ (t$\rightarrow$qH) decays, only the H$\rightarrow$$\mathrm{b\bar b}$ decay is selected. No significant deviation is observed from the standard model prediction. Observed (expected) upper limits are obtained at 95% confidence level, which are B(t$\rightarrow$uH) < 0.47% (0.34%) and B(t$\rightarrow$cH) < 0.47% (0.44%).
