Fremont ADU Builder.
large lots, efficient review.
Fremont ADU work moves through City of Fremont Community Development. Fremont's larger typical lot sizes (especially Mission and Warm Springs) make detached ADU work more straightforward than in dense East Bay neighborhoods, and the city's plan-check has a reputation for moving efficiently.
