Lafayette jumbo loans and 2026 loan limits.

Lafayette became a city in 1968. Mount Diablo Boulevard is its main street, running beside Highway 24 through a downtown of shops and restaurants, with the BART station just across the freeway. Lafayette Reservoir, with a paved path around it, is at the western end of town. Briones Regional Park lies to the north, and the Lafayette-Moraga Regional Trail follows an old railway line south along the creek.

Downtown and the streets near it have condominiums, townhouses and apartment buildings, many of them recent. Beyond are neighborhoods of single-story ranch houses from the 1940s to the 1960s, on lots large enough for a pool and a lawn. In the side valleys and on the ridges are larger properties, some of several acres, with custom houses, barns and vineyards. Streets outside downtown often have no sidewalks.

It depends on the kind of home: an association review for a condominium, a remodel history for a ranch house, and the land for a hillside or acreage property.

For a condominium near downtown, the lender reviews the homeowners association: budget, reserves, insurance, owner-occupancy and any lawsuit. In a newly built project, lenders also ask how many homes have sold. Condo financing is described on the Loan options page.

The city protects its ridgelines and hillsides with building rules of its own, which limit where and how large a house can be on a slope. That affects what an appraiser can assume about a lot. Creeks run through many neighborhoods, with setbacks, and a few lots are in a flood zone.

Check any hillside address on the state’s fire hazard map. A lender needs homeowners insurance in place, and near open land it takes longer to arrange. Larger properties may have a well, a septic system or a private road, each of which a lender’s appraiser reports.

Happy Valley is northwest of downtown, north of Highway 24, along Happy Valley Road and Upper Happy Valley Road. The roads wind uphill past large, wooded lots toward the open hills.

This is Lafayette’s area of large lots. Properties of an acre or more are common, with houses set back from lanes that have no sidewalks or street lights. Homes range from older ranch houses to large custom ones, and some keep a barn, a paddock, a vineyard or a tennis court. For a lender, an appraisal here takes care: the appraiser weighs the house, the land and the outbuildings, and finds fewer close matches than in a tract. A second appraisal may be asked for on a larger loan. Some properties are on septic systems or private lanes, so ask for the records and any road agreement. A few horses for your own use do not change the loan; boarding for pay would. The upper valley borders open land, so check the state’s fire hazard map.

Burton Valley is in the southern part of Lafayette, along St. Mary’s Road and Rohrer Drive, on the way to Moraga. Las Trampas Creek and the Lafayette-Moraga Regional Trail run along its edge, and Lafayette Community Park is part of it.

It is a valley-floor neighborhood, built mostly from the 1950s to the early 1970s with single-story ranch houses on regular lots. Two creeks, Las Trampas and Grizzly, wind through it. A large number of the houses have been remodeled, extended or rebuilt, some with a second story. Appraisals are among the more direct in Lafayette, because similar houses sell regularly and the appraiser can match size, age and condition. Check permits for additions. Lots backing onto the creek may have a flood zone or a setback, and the lender’s flood certificate will show whether flood insurance is needed. Check the state’s fire hazard map for the address, above all near the hills. A permitted accessory unit generally does not change the one-unit limit.

Reliez Valley is in the northeastern part of Lafayette, along Reliez Valley Road, which runs through the valley north of Highway 24, toward Briones Regional Park and Martinez. The city boundary winds through the valley, so some homes are in Lafayette and some are in unincorporated Contra Costa County.

Homes include single-story ranch houses of several decades on generous lots, later subdivisions of bigger houses, and hillside custom homes with views toward Mount Diablo. For a loan the county is the same throughout, so the limit does not change with the boundary. What changes is who issues permits and which local rules apply, so check the title report for the city or county. An appraiser notes lot size and slope and whether the house is on a through road or a private lane. The valley is close to open grassland and the regional park, so check the state’s fire hazard map and collect insurance quotes early. Some lots have room for horses or a second building. Tell Sam what is on the property, since outbuildings and second units are valued differently.
