Millbrae is a transit-connected Peninsula community located near SFO and anchored by a combined BART and Caltrain station. The city features a mix of post-war homes and newer construction across established residential neighborhoods. With convenient access to both San Francisco and Silicon Valley, Millbrae draws families and commuters who want a suburban setting with strong transit links. Custom home building in Millbrae allows homeowners to update older homes with modern layouts and finishes.
Millbrae is a compact Peninsula city with a residential character shaped by its post-war development. Much of the city's housing stock was built in the 1950s and 1960s, with concentrations of ranch-style and tract homes in the Meadows, Central Millbrae, and Lomita Heights neighborhoods. The Mills Estate area features larger lots and more varied architecture, including some newer custom construction. Many of these older homes have functional but dated layouts that homeowners are updating to meet current needs.

The most popular project types in Millbrae include kitchen and bathroom remodeling, home additions, and ADU construction. Kitchen remodels are common because original floor plans often feature closed-off kitchens separated from living areas. Home additions allow families to add bedrooms or expand living space without leaving their neighborhood. ADU construction benefits from Millbrae's strong transit access: the combined BART and Caltrain station makes rental units especially attractive to commuters.

Millbrae's Building Division handles residential permits for the city. The permitting process for new construction and significant additions includes plan review and may require design compatibility evaluation depending on the scope. Lot sizes in Millbrae are moderate by Peninsula standards, making efficient design important for additions and detached ADU projects. Hillside lots in the Highlands and Lomita Heights areas may require additional engineering for grading and foundation work.

Homeowners invest in Millbrae construction because the city offers a practical combination of transit access, proximity to SFO, good schools, and a quiet residential setting. The city's location between Burlingame and San Bruno provides access to dining and shopping in neighboring downtowns. Home values in Millbrae have been strong, and quality renovations and additions hold their value well in this transit-oriented market.
