Perpetual Savings Bank said this week that several would-be buyers have made offers for the Washington Building at 1440 New York Ave. NW, its strategically located 11-story office building within sight of the White House, but so far it has rejected all of them as too low.

Perpetual acknowledged the offers in an unusually terse press release that was void of any substantive information about the bids it had received on the Beaux Arts building, which was built in 1927 and recently renovated. Perpetual acquired the 215,000-square-foot building in 1983 as part of a package when it purchased Interstate Federal Savings and Loan. Since then, the building has been on the sales market, but Perpetual said all offers so far have "been deemed unsatisfactory."

"Other than that, I can't comment," said Perpetual spokesman James Pastore. He declined to say how many offers or what specific dollar amounts have been made for the building.

The District has assessed the building as worth $34 million.

The value of building permits issued in the nation's 200 largest cities declined by 2.4 percent during the first quarter of 1987, dropping from $12.5 billion to $12.2 billion, according to Dun & Bradstreet Corp.

But among cities where the value of building permits increased, Alexandria ranked second in the nation behind Miami. Dun & Bradstreet reported that Alexandria's total increased from $9.9 million in the first three months of 1986 to $62.6 million in the first quarter this year, a 530.3 percent gain. Miami's total increase was 1,154 percent, from $4.8 million to $59.8 million.

"The current decline in building permit values largely reflects the ongoing economic pressures in the oil-producing states," according to Joseph W. Duncan, Dun & Bradstreet's corporate economist and chief statistician. "For example, in the 19 cities Dun & Bradstreet tracks in Texas, the total value of permits issued was down 40 percent from the first quarter of 1986."

New York, with $811.4 million, ranked first in total building permit value, followed by Los Angeles ($705 million) and San Diego ($447.1 million).
