After August 1st, it'll be one to obtain the permit :
Starting Aug. 1, when the 2004 California Electrical Codes automatically take effect, residents will have to apply for a city building permits to replace or add wall, porch and ceiling lamps, light switches, electric receptacles, and other common do-it-yourself chores.
So changing that noisy electrical switch with a quieter mercury switch will cost a lot more. Besides the costs of the new switch, there’ll be the $81 basic permit fee plus an additional surcharge of $2.15 for each receptacle, outlet or switch and—if you want to add more—$21.50 for altering or changing wiring.
Under the current city code, such small changes can be made without permits and inspections; starting Aug. 1, not so.
