New construction in Sunnyvale.
Sunnyvale's new construction landscape is shaped by an all-electric reach code, an aggressive Heritage District overlay across the older central neighborhoods, and a R-1 daylight-plane / second-story FAR cap pairing that decides massing before design begins.
R-0/R-1 SFR rebuilds across the older central neighborhoods, R-2 small multifamily, and downtown-adjacent multifamily within the precise plan.

New single-family permits in Sunnyvale are issued by City of Sunnyvale Community Development Department — Building Safety Division; California Title 24 Part 6 and CALGreen Part 11 apply statewide on top of any Sunnyvale reach-code amendments.
“Treat the project as all-electric and confirm Heritage District status before scoping. The daylight-plane and second-story area cap together dictate roof geometry on most R-1 rebuilds.”
What gets built in Sunnyvale.
- ▸Heritage District R-1 careful rebuild
- ▸Cherry Chase teardown-rebuild
- ▸Downtown Specific Plan multifamily
Does the lot work?
Daylight-plane, second-story FAR cap, and rear-yard rules dominate R-1 envelope; protected-tree ordinance further shapes siting.
Zoning and entitlement.
Sunnyvale uses R-0, R-1, R-1.5, R-2, R-3 and R-4 districts plus the Downtown Specific Plan; R-1 single-family rules govern FAR, daylight plane, and second-story area.
Most R-1 SFRs are ministerial; Heritage District and other historic-resource overlays trigger design review and demolition findings.

Sitework & utilities.
Grading & drainage. Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Sunnyvale Community Development Department — Building Safety Division; sloped parcels require geotech and an erosion-control plan.
Utility upgrades. PG&E electric/gas; City of Sunnyvale water (Hetch Hetchy + local supply) and sewer; coordinate service upsize early.
Sewer / septic. Municipal sewer service in developed Sunnyvale parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping.
Site access & staging. Site access in Sunnyvale can require temporary street-use or encroachment permits depending on street width, on-street parking restrictions, and proximity to schools or transit corridors.
Foundation & seismic.
Regional Hayward, Calaveras, and San Andreas systems; CGS liquefaction zones touch parts of the city near the Bay.
Soils. Alluvial fan deposits and expansive-clay layers; geotech-driven foundation design is standard.
Energy code & green building.
California Energy Commission Climate Zone 4. New single-family homes must comply with the current Title 24 Part 6 envelope, HVAC, hot-water, and rooftop solar-PV requirements.
CALGreen Part 11 mandatory measures (≥65% C&D waste diversion, water-efficient fixtures, indoor-air-quality measures) apply to all new homes. Sunnyvale has adopted an all-electric reach code for new construction with limited exceptions; confirm scope at intake.
Solar resource. Strong California solar resource; Title 24 PV sizing is calculated per conditioned floor area and orientation. Heating / cooling. Mild marine-influenced summers; cooling loads are modest but heat-pump HVAC is now the default new-construction spec under Title 24. Rainfall. ~20 in/year, concentrated November–March; sequence slab pours and exterior envelope work around the wet season to stay compliant with the LID plan.
Constraints that matter here.
- Flood
- Limited FEMA SFHA — primarily along Calabazas Creek and bayside areas; verify on the FEMA MSC.
- Soils / foundation
- Alluvial fan deposits and expansive-clay layers; geotech-driven foundation design is standard.
- Site access / staging
- Site access in Sunnyvale can require temporary street-use or encroachment permits depending on street width, on-street parking restrictions, and proximity to schools or transit corridors.
