Winter is historically the slow month for home building.But that isn’t the case this year in Manteca.If all of the single family home permits in review as of Feb. 28 are issued by the end of this month, Manteca builders will have started 107 new homes in the first three months of 2016.If the pace doesn’t pick up — although it usually does as the temperature rises — Manteca is on target to start at least 428 new single family homes this year.There are indications, however, that the number of homes that will be started this year in Manteca could easily surpass 500. The last time more than 500 homes were built in Manteca was in 2006 when there were 549 new homes addedThe current numbers reflect builders that have buildable lots to sell.Three builders are in the process of getting lots ready to build on and sell for new homes. The expectation is they will be ready to move forward by summer.
