New construction in San Jose.
San José's new construction landscape combines an all-electric reach code, Hillside (HS) zoning across the foothills, and lowland FEMA SFHA along Coyote Creek and the Guadalupe River — each capable of changing scope and cost materially.
R1 infill and rebuilds in Willow Glen, Rose Garden, and Almaden; multifamily near transit; hillside customs in foothills.
Alpha Dream Construction · CA Lic. #1145233
San José issues new home permits through Planning, Building & Code Enforcement (PBCE) — Building Division; the city has adopted an all-electric reach code for new construction with limited exceptions.
“Confirm reach-code scope, FEMA SFHA status, and hillside zoning before scoping. Expansive-clay soils make geotech effectively mandatory.”
What gets built in San Jose.
- ▸Willow Glen SFR rebuild
- ▸Rose Garden infill
- ▸Almaden hillside custom
- ▸Multifamily near transit
Does the lot work?
Hillside lots constrained by slope, ridgeline protection, and biology. Flat infill mostly governed by FAR and setbacks.
Zoning and entitlement.
San José uses R-1 with detailed FAR/coverage rules; Hillside (HS) and Conservation zones in foothills add slope and biology constraints.
Single-family Design Review applies in some districts; hillside permits require Planning Commission for larger projects.
Jurisdiction & plan check.
New homes in San Jose are permitted by City of San José Planning, Building & Code Enforcement (PBCE) — Building Division.
Accela-based portal; plan check thorough on Title 24 and structural.
City inspectors; online scheduling.

Sitework & utilities.
Grading & drainage. Hillside grading regulated by HS zoning; LID stormwater required.
Utility upgrades. PG&E electric/gas; San José Water Company or San José Municipal Water for water; sewer through ESD.
Sewer / septic. City sewer in developed areas; foothill parcels may still be on septic.
Site access & staging. Foothill parcels with narrow access roads complicate logistics.
Foundation & seismic.
Hayward, Calaveras, and San Andreas fault systems regional; CGS EQ Zone App liquefaction zones in some lowland areas.
Soils. Alluvial fan deposits in the valley; expansive clays common — geotech standard.
Energy code & green building.
Climate Zone 4. Title 24 Part 6 with PV; San José adopted an all-electric reach code for new construction with limited exceptions — verify current scope.
CALGreen Part 11 applies plus city green-building requirements.
Solar resource. Excellent solar resource (~5.5 kWh/m²/day). Heating / cooling. Hot dry summers; cooling loads significant. Rainfall. ~15 in/year, concentrated winter.
Constraints that matter here.
- Hillside
- Almaden and east-foothill Hillside (HS) zoning with slope-based limits.
- Wildfire / WUI
- Foothill parcels in VHFHSZ; Chapter 7A applies.
- Flood
- FEMA SFHA along Coyote Creek, Guadalupe River, and some lowland areas.
- Soils / foundation
- Alluvial fan deposits in the valley; expansive clays common — geotech standard.
- Site access / staging
- Foothill parcels with narrow access roads complicate logistics.
Common risks: Expansive-clay geotech surprises · Hillside slope-band reductions · Reach-code scope misread late

Why San Jose isn’t like the next city over.
All-electric reach code + extensive HS zoning + creek-corridor SFHA + expansive clay geotech.
The Alpha Dream Construction process.
- 1 · Feasibility. Parcel + zoning + overlay screen before any design dollar is committed.
- 2 · Schematic + budget. Massing options, written budget range, schedule with permit risk noted.
- 3 · Design development. Architect, structural, MEP, Title 24, and geotech aligned on one set.
- 4 · Plan check. City of San José Planning, Building & Code Enforcement (PBCE) — Building Division submittal, comment cycles, and entitlements run in parallel.
- 5 · Construction. One superintendent, weekly owner reports, photo-documented hold points.
- 6 · Closeout. Final inspections, warranty walkthrough, O&M binder.
Who you’re working with.
Alpha Dream Construction is a CA Lic. #1145233 general contractor serving California homeowners and developers. Every project is run by a single accountable superintendent and documented in writing from feasibility through closeout.
San Jose new construction · FAQ.
- Does San José have an all-electric requirement?
- Yes — San José adopted an all-electric reach code for new construction with limited exceptions. Verify current scope at intake.
- What is Hillside (HS) zoning?
- Zoning overlay applied to foothill parcels; adds slope-based FAR, ridgeline protection, and grading limits.
- Is my lot in a FEMA flood zone?
- Lots along Coyote Creek and the Guadalupe River are commonly in SFHA; check the FEMA MSC.
- Do I need geotech?
- Effectively yes — expansive-clay soils dominate much of the valley and most new SFRs require geotech-driven foundation design.
- Does Chapter 7A apply?
- Foothill parcels in VHFHSZ — yes. Valley flatland parcels — generally no.
