Local Knowledge, Local Results
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 Permits & Rules

- Historic areas — Exterior changes in Fremont's historic districts, including Niles and Mission San Jose, can require design review.
- Seismic hazard zones — The Hayward Fault crosses Fremont; properties in fault or liquefaction zones may need geotechnical reports and specific foundation design.
- Hillside lots — Eastern hillside properties can require grading, drainage and geologic review.
- ADUs — Approved ministerially under state law; garage conversions need no replacement parking.
- Remodels — Permits are required for structural, plumbing, electrical and mechanical changes.

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.
The type of ADU matters most: converting a garage usually costs far less than building a new detached unit. After that, size, utility trenching and the sewer connection, foundation and soil conditions, and finish level drive the price. We give you a fixed price after a free site visit.
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.
Scope is the biggest factor. A same-layout refresh, a signature remodel with semi-custom cabinetry and layout changes, and an estate-level custom kitchen are very different projects. Moving plumbing, gas lines or walls, cabinetry and countertop selections, appliances and city permit fees also play a role. We give you a fixed price after a free site visit.
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.
