    Power line going to workshop is too low?

    I swear I can almost reach up and grab it stand ling by the meter so I want to say its 7ft tall. You aren't going to be driving any vehicles under it, that's for sure. I thought power lines were supposed to be atleast 12ft tall? Or is that only the line connected to the power poles?

    Generally 10ft, 12 ft over driveway and more in other cases.

    all depends on where it originates, what it crosses and where it stops.
    Odds are all or most of the work/money to raise it is on you
    ONLY if it originates on power company pole and crosses a public road, alley, etc is it possibly partially on the power company. It would have to be lower than 16-18 ft (depends on what it crosses) on the power pole and at least that height on your building where it is attached. THEN if it is too low for what it crosses the power company, inspector and you would have to have a meeting to determine who does what to get it higher. If the power pole in on your lot or adjunct to your lot and crosses no public space the height is a lot lower than crossing a public street.
    "I swear I can almost reach up and grab it stand ling by the meter so I want to say its 7ft tall" THIS is on your nickle, attachment point is way too low on your structure.

    From 2017 NEC. I don’t think many communities have adopted the 2020 cycle, yet.
    Even then, local municipalities can choose to amend the NEC as they see fit.

    230.24
    A) Above Roofs. Conductors shall have a vertical clearance
    of not less than 2.5 m (8 ft) above the roof surface. The vertical
    clearance above the roof level shall be maintained for a
    distance of not less than 900 mm (3 ft) in all directions from
    the edge of the roof.

    (B) Vertical Clearance for Overhead Service Conductors.
    Overhead service conductors, where not in excess of 600 volts,
    nominal, shall have the following minimum clearance from
    final grade:
    (1) 3.0 m (10 ft) — at the electrical service entrance to build‐
    ings, also at the lowest point of the drip loop of the build‐
    ing electrical entrance, and above areas or sidewalks
    accessible only to pedestrians, measured from final grade
    or other accessible surface only for overhead service
    conductors supported on and cabled together with a
    grounded bare messenger where the voltage does not
    exceed 150 volts to ground
    (2) 3.7 m (12 ft) — over residential property and driveways,
    and those commercial areas not subject to truck traffic
    where the voltage does not exceed 300 volts to ground
    .....
    (exceptions for over 300 volts nominal)


    230.26 Point of Attachment. The point of attachment of the
    overhead service conductors to a building or other structure
    shall provide the minimum clearances as specified in 230.9 and
    230.24. In no case shall this point of attachment be less than
    3.0 m (10 ft) above finished grade.
    edit: The NEC is now available online for free (requires you to register an email). Not searchable via keywords, nor can you highlight and copy, but if you’re familiar with its layout, you can eventually find what you’re looking for.
    That link we have in the stickies has been dead for years. Maybe re-title it to point to the NFPA website?

    I can't help with the code but I can offer this, for what it's worth. About 10 years ago we had a bad winter storm (yet was unusually warm) and a tree split. The part that broke took out the mast going to the meter on the side of his house. Of course the power company came out very quickly to cut power but when they showed up they told me that while they owned everything above the meter it was my father who had to pay for repairing it. His power line was also pretty low and he would use a long piece of wood to prop it up each time he would park his RV on that side of the house. Since he was paying to have an electrician come out we had him raise the mast up another 4'. You may want to call your power company and ask them. My father had no choice and had to pay "emergency" prices since going without power in the middle of winter isn't an option unless you have a wood stove in Vermont. But it may not be too expensive if it's a normal service call and you can get a few prices ahead of time.
