It’s a deal — Albany style, that is.

New York City rent regulations will remain in effect for the next four years — with the annual household income threshold at which apartments can be deregulated increased from $175,000 to $200,000.

Which is precisely the level Assembly Speaker Sheldon Silver originally had in mind to qualify for his so-called “millionaire’s” tax.

Only in New York, then, are “millionaires” so beset that they are in need of rent control.

Or, more specifically, only in Albany.

Gov. Cuomo, Silver and Senate Majority Leader Dean Skelos yesterday reached a “framework agreement” on most pending issues — except for same-sex marriage — that will allow legislators to skate after the votes are tallied today.

The good news, approximately, is that the deal also includes a much-needed 2 percent local property-tax cap — redeeming a Cuomo campaign goal to which Skelos also pledged allegiance.

Alas, the cap appears to come with a five-year, built-in expiration date. That’s better than nothing at all, but — pending the parsing of details — it could mean that the cap will be hard-pressed to survive the pressure sure to be brought against it as soon as it takes effect.

The expectation had been that the cap would be institutionally linked to the extension of rent regulations in such a way that any “sunset” clauses would affect them both, simultaneously.

Given that rent regulations are never going to expire — they’ve been in effect since 1946, after all — such a linkage would’ve given the tax cap a fighting chance for long-term survival.

Indeed, it seems that the teachers and other public-sector unions already are at work eroding the cap. Silver, nominally a tax-cap opponent, originally proposed a bill with no expiration at all — but Cuomo and Skelos, purportedly strong supporters, somehow managed to negotiate a sunset into the bill.

Go figure.

Again, the fine print matters.

And none of this is meant to minimize the importance of the tax cap — it’s a critical first step in bringing the cost of local government in New York to something approximating rational levels.

And who knows?

Perhaps New Yorkers, who have become used to ever-spiraling property-tax rates, will become so fond of the cap that they’ll demand renewal in five years.

Stranger things have happened.
