How to say one street branches from another?

Question

My house is located on a side street that branches from a main street. If I wanted to formally write my home address, how should I do it? I'm thinking:

[Side street name], branching from [main street name]

Edit:

I'm going to send this information to US State Department via this web-form:

Answer 1

Addressing conventions vary from country to country. In the US, for example, a street address does not usually contain information about so-called "cross-streets", but takes this basic format:

{Number} {Street}  {Floor, Apartment, Condo#, etcetera)
{CityName}, {StateAbbreviation} {PostalCode}

such as

1234 Elm Street Apt 6
Albany, NY 12203

You could say that your street intersects a particular street.

Answer 2

The usual phrasing is "off [main street]" (see definition 1b, MW). In speech you will often hear "off of", though there's some debate over whether this is valid usage.

Tᴚoɯɐuo is correct, though, that if you want to actually write down your address rather than just describe its location, you would follow the standard format for the relevant area.
