Interestingly you are not the first person to request this and I dismissed it the first time as musically-rhythmical-but-not-very-metrical, but now that two of you have requested it, I guess I should take a look!

Here's my read of the first verse.

– ◡ ◡ ◡ – ◡ ◡ || ◡ – ◡ – Welcome to the neighborhood! You just moved in? ◡ ◡ ◡ – ◡ ◡ ◡ – – ◡ ◡ – ◡ ◡ – ◡ I saw the truck outside and brought over some cookies to meet you ◡ ◡ – ◡ ◡ ◡ – – ◡ ◡ – ◡ – ◡ I'm a member of the Homeowner's Association ◡ ◡ ◡ – – ◡ ◡ || ◡ – ◡ ◡ – And if you need anything, I'm just down the street ◡ – – ◡ ◡ – ◡ – ◡ – – ◡ You might want to peruse the HOA pamphlet ◡ ◡ ◡ – – ◡ || ◡ – ◡ – ◡ – ◡ – ◡ – – There is a lot in it, and I don't mean to overwhelm your first day ◡ ◡ – – ◡ ◡ – ◡ – ◡ – But the backyard needs a little TLC ◡ – ◡ – – ◡ ◡ – ◡ ◡ – || ◡ – ◡ – The weeds are right up to the property line, that's not okay

Much of the song is tetrameter because that's what fits the music the best, but part of the song's style is that a lot of the lines have significantly more syllables (including one or two extra stresses) than would be required to keep a steady tetrameter rhythm, and/or the lexical stress doesn't match the music.

happenchance and trisectrices

I'm sure you can figure out why
