Bakersfield home sales were up in March and marketing times were down as the city’s market for single-family residences continued its transition to the peak season, newly released data show.

The number of Bakersfield homes sold last month jumped about 22 percent to 507, or 4.1 percent more than a year earlier, according to a preliminary report by local appraiser Gary Crabtree. The median number of days homes in the city spent on the market dropped 29 percent from February to 34, or 6.3 percent more than March 2015.

Meanwhile, the median sale price — the point at which half the homes sold for more and half went for less — was unchanged in March at $220,000, Crabtree reported. That’s 6 percent more than the median price a year before, when it was $207,500.

The state Franchise Tax Board is inviting Kern County’s poorest residents to sign up for free tax preparation service Sunday aboard a bus promoting California’s new earned income tax credit.

Reservations are required; they can be made by calling 834-1820.

As of late last month, about 8,500 Kern taxpayers had filed state tax returns claiming the tax credit, which can total up to $2,653 for families, depending on qualifications regarding their income and number of dependent children. The state has estimated up to 20,000 county residents may be eligible for the credit.

A ribbon-cutting Wednesday in Delano celebrated the opening of a solar energy installation expected to result in a 40 percent power bill reduction at the city’s wastewater treatment plant.

The privately funded energy plant at 1107 Lytle Ave. was built by German company BayWa AG. It has been sold to WGL Energy Systems, based in Washington, D.C.

The wastewater plant treats about 7.2 million gallons per day from industry and about 52,000 residents.

The U.S. Supreme Court has declined to review a case challenging Tejon Ranch Co.’s right to develop a 3,450-home mountain resort near Lebec.

The move lets stand a June ruling by the 9th U.S. Circuit Court of Appeals that the company holds legitimate title to the land where it proposes to build Tejon Mountain Village.

The Supreme Court’s decision effectively ends a lawsuit filed by Kern County resident David Laughing Horse Robinson, who had argued the property actually belongs to the federally unrecognized Kawaiisu Tribe of Tejon, of which he claims membership.
