Local Knowledge, Local Results
Why Milpitas HomeownersChoose True Builders.
Milpitas has established single-family neighborhoods west of I-680 and hillside areas to the east. Two-story tract homes often have room for a Junior ADU in an attached garage or ground-floor wing, while larger lots can take a detached ADU. Hillside properties can involve additional grading and geologic review, and some newer neighborhoods add HOA approval to the process. We work with the City of Milpitas so your project is designed to be approved.
Every project includes a fixed construction price and one project manager.

Milpitas Permits & Rules
What to Know Before You Build in Milpitas.
We handle every permit. Here's the short version of what Milpitas typically requires for common projects:
- ADUs & JADUs — Approved ministerially under state law. A single-family lot can have both an ADU and a Junior ADU.
- Hillside areas — Properties in the eastern foothills can require geotechnical reports and added grading and drainage review.
- Additions — Must meet zoning setbacks, height and lot coverage limits for your district.
- Remodels — Building, plumbing and electrical permits are needed when layouts, drains or circuits change.
- HOA communities — Some Milpitas neighborhoods require HOA architectural approval in addition to city permits; we help prepare those submittals.

MILPITAS FAQS
Local Questions, Answered.
It depends on your lot and budget. A Junior ADU inside the home is usually fastest and least expensive, a garage conversion creates a separate unit, and a detached ADU offers the most privacy. We compare options during a site visit.
Converting a bedroom and sharing the main home's bathroom is the lowest-cost option. Adding a private bathroom, or converting an attached garage, costs more because of new plumbing, insulation and entry work. We give you a fixed price after a free site visit.
If your home is in an HOA community, exterior changes and ADUs may need HOA architectural approval. California limits how far HOAs can restrict ADUs, but their approval process still applies.
Construction for a single-room addition typically takes 3–4 months, and a primary suite addition 4–6 months, plus time up front for design, engineering and permits.
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.
Plans and permits typically take 8–14 weeks, and construction of a detached ADU usually takes 16–22 weeks once permits are issued, so most detached ADUs are finished in about 6–9 months. Garage conversions and JADUs are usually faster.
