General Contractor in Milpitas

Milpitas has a mix of older tract housing and newer development. On the older stock, additions and ADUs both pencil — the deciding factor is usually where utilities run and how much usable rear yard is left.

The Milpitas rule that catches people out is construction waste. The City applies CALGreen construction and demolition recycling to residential work with no dollar threshold at all. Its own table says it applies to a newly constructed building, or an “addition or alteration that increases conditioned space”, or a demolition permit pulled in preparation for one. A heated 260 square foot addition triggers it exactly as a new house does. The requirement is to divert 65% of project waste from landfill.

It is also a two-part filing that lives in two different departments, which is where jobs get stuck. Recycling Report Part I goes to Building before the permit is released — the City states plainly that the permit will not be released without it. Part II goes to Public Works before final inspection. And a hauler weight ticket is not a diversion report: tonnage proves what left the site, while the diversion certificate has to come from the receiving facility. Milpitas also has an exclusive franchised hauler for debris boxes, so a sub who brings their own bin can cost you the tonnage credit.

Practically, that means segregating a clean wood box and keeping concrete separate. Concrete is heavy and close to fully recyclable, so those tickets move the diversion percentage more than anything else on site. We put the service address and permit number on every debris-box work order so the tonnage can actually be tied back to the permit. For the addition side, Engineering (408-586-3329) and Planning (408-586-3279) are the two numbers to call about feasibility before anyone starts drawing.

We work throughout Milpitas — whether you're in McCarthy Ranch, the Great Mall area, Sunnyhills, or Parktown, the build is the same standard.

Permits. Work in Milpitas is permitted through the City of Milpitas Building & Safety Division. We carry the submittal and the plan-check corrections — that is our job, not yours.

Milpitas publishes an ADU permit-fee assistance program and runs scheduled "ADU Monday" appointments with Building, Planning and Land Development together. Worth using before you commit to a design.

Pre-approved ADU plans. Milpitas publishes a gallery of pre-approved ADU plans that homeowners can build from. Since AB 1332 took effect on January 1, 2025, California cities have had to run a pre-approved ADU plan program and post the approved plans publicly. Where a usable plan exists it can take real time and design cost out of a project, because the design has already been reviewed and only the site-specific work is left.
