My avionics technician passed my airplane for its 24 month avionics check. The avionics technician forgot to remove black tape covering 3 of the 4 static holes. I was flying out of ZZZ and received an IFR to VFR clearance. On takeoff; my airspeed indicator was working fine; and my altitude indicator stopped at 400 ft. Just like the books tell you; the altitude indicator acted like a barometer. ATC had showed me squawking 450 ft; and my copilot gauges seemed to work. I began to fly using the copilot instruments. I was on flight following and asked ATC to return to ZZZ. I declared an emergency. They vectored me to ZZZ VOR approach. I made a safe landing. After leaving the plane I found the black tape covering the static holes and removed it. I contacted my avionics technician and told him about the problem. I have grounded the airplane until my avionics technician retests my avionics. It was my fault for not checking the static holes before my flight.
