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.

Most JADUs cost about $55,000–$95,000 when converting a bedroom with a shared bath, and up to about $190,000 with a private bath or an attached-garage conversion.

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.

Most Milpitas 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.

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.
