Why Fremont HomeownersChoose True Builders.
Fremont is large and varied: historic homes in Niles and Mission San Jose, post-war tracts in Centerville and Irvington, and hillside properties to the east. That variety changes the permit path. Historic areas have design review, hillside lots can require geotechnical study, and parts of the city fall within earthquake fault or liquefaction hazard zones that affect foundation design. We sort out those requirements with the City of Fremont before you commit to a design.
You’ll get a fixed construction price and one project manager.

FREMONT FAQS
Local Questions, Answered.
It can. Projects in mapped earthquake fault or liquefaction zones may need a geotechnical report and a foundation designed around it. We check hazard maps for your parcel during feasibility.
Most Fremont ADUs run about $150,000–$250,000 for a garage conversion and $275,000–$600,000 for a detached unit, depending on size, soils and finishes.
Yes. Exterior changes in historic areas are reviewed for compatibility with the district, while interior remodels generally need only building permits. We prepare drawings with that review in mind.
Most garage conversions to an ADU take 4–6 months including design, permits and construction.
Most Fremont kitchen remodels fall into three levels: about $60,000–$95,000 for a refresh, $95,000–$150,000 for a signature remodel with semi-custom cabinetry and layout changes, and $150,000–$250,000 or more for an estate-level custom kitchen, plus city permit fees.
It depends on scope: remodeling select spaces such as the kitchen and bathrooms takes about 4–5 months, a comprehensive remodel with structural changes 6–8 months, and a complete home redesign 8–12 months or more.
