Scarsdale is 92% owner-occupied and has no industrial zoning at all

Only if you choose the option that requires it, and never without showing you first. At survey we photograph the door, the frame, the hinge side and the existing hardware, and we come back with the three realistic options and what each one does to the woodwork.

On a lot of Scarsdale houses the practical answer is to leave the front door entirely alone and control a side or mudroom door electrically instead. Families overwhelmingly come and go through the side door anyway; the front door is for guests, and guests are perfectly well served by a video door station and a remote release on the storm door or vestibule rather than on the primary leaf.

Length is only one of the questions. The others are: does the gate’s swing arc clear the apron and the road, is there room to place operating controls at least six feet from the gate as UL 325 requires, is there space for photo eyes on both sides of the entrapment area, and can a delivery truck actually turn around inside the gate or will it have to reverse into the street.

On a short apron the honest answer is sometimes no, or not as a swing gate. A slide or bi-fold operator solves the arc problem but needs run-back room along the fence line. And if the driveway is short enough that a car waits in the road while the gate opens, that is a safety consideration worth naming before you spend the money, not after.

Enough that we measure the cable path rather than the sight line, and on these lots the two are not close. The wire goes from the gate post along the fence line, around whatever stone wall or planting bed the drive curves past, to the nearest point it can enter the house, and then down to wherever the panel lives. On a Fox Meadow or Heathcote property where the house sits well back behind mature trees, that walk routinely comes out half again longer than the number an owner guesses from the road, and a Cat6 channel carrying power over Ethernet stops behaving at 328 feet including patch cords.

The number that costs more, though, is power. There is rarely an outlet anywhere near a Scarsdale gate, so the operator, the heater in its cabinet and the entry station all need a circuit brought out by an electrician. Trenching once for both is the largest single saving available on a job like this, and it is only available if the electrical scope is settled before anyone opens the ground. The third consideration is surge. A metal gate at the end of a long run on a wooded lot takes lightning transients the house never feels, so a long outdoor leg gets terminated in a protected, properly grounded enclosure rather than landed straight on the recorder.

Fewer of them, placed on purpose. Decide what each camera is for (identify a person at a specific point, or observe an area) and accept that one camera cannot do both. Three or four identification views at the gate, the front door, the side door and the motor court, plus one or two wide overviews, beats a dozen units on every corner and produces better evidence.

Physically: mount under eaves and soffits rather than mid-wall, use housings in a color that matches the trim, keep cable inside the structure wherever possible, and avoid the wide-angle dome on a bracket that reads as commercial from the street. Where a camera would be conspicuous and useless anyway (aimed into a hedge, or through glass), we will say so rather than sell it.

That is a question for the Village of Scarsdale building department, and it is worth asking rather than assuming. Scarsdale is a coterminous town and village, so there is one building department rather than two, which is simpler than most of the county.

Straight low-voltage signaling and communication work often falls outside a permit requirement, but a gate operator does not exist in isolation: it needs a power circuit, and that is licensed electrical work performed by an electrician, not by us. Gates may also involve setback, height or fence provisions in the village code. We flag all of that at survey so it is priced and scheduled rather than discovered.
