New construction in Redwood City.
Redwood City is two cities at once: an Emerald Hills hillside community with R-1-H slope rules, and a Redwood Shores bayside community with FEMA SFHA and Bay Mud foundations. New construction decisions diverge sharply between the two sides.
R-1 rebuilds in Mt. Carmel and Roosevelt, hillside customs in Emerald Hills, and multifamily near downtown and Redwood Shores.

New single-family permits in Redwood City are issued by City of Redwood City Community Development & Transportation Department — Building Division; California Title 24 Part 6 and CALGreen Part 11 apply statewide on top of any Redwood City reach-code amendments.
“Identify which 'side' of Redwood City your lot is on before scoping — Emerald Hills triggers hillside review and geotech; Redwood Shores triggers flood freeboard and Bay Mud foundations.”
What gets built in Redwood City.
- ▸Mt. Carmel R-1 rebuild
- ▸Emerald Hills hillside custom
- ▸Redwood Shores bayside SFR
Does the lot work?
Buildable envelope set by R-1 coverage, setbacks, and 30-foot height limit; R-1-H adds slope-band density caps and ridgeline rules.
Zoning and entitlement.
Redwood City uses R-1 sub-districts (R-1, R-2-A, etc.) plus Hillside Residential (R-1-H) in Emerald Hills; downtown precise plan controls the urban core.
Most R-1 SFRs are ministerial; R-1-H hillside parcels add Architectural Review and slope-based density rules.
Jurisdiction & plan check.
New homes in Redwood City are permitted by City of Redwood City Community Development & Transportation Department — Building Division.
Plan check rigorous on Title 24, structural lateral design, and (in Redwood Shores) FEMA elevation requirements.
City of Redwood City Community Development & Transportation Department — Building Division schedules inspections through its permit portal; foundation, framing, rough trades, insulation, drywall, and final are the standard hold points for new SFRs in Redwood City.

Sitework & utilities.
Grading & drainage. Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Redwood City Community Development & Transportation Department — Building Division; sloped parcels require geotech and an erosion-control plan.
Utility upgrades. PG&E electric/gas; California Water Service (Cal Water) for water in most areas; City for sewer — coordinate service-upgrade lead times.
Sewer / septic. Municipal sewer service in developed Redwood City parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping.
Site access & staging. Site access in Redwood City 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.
The San Andreas Fault zone is west in the hills; CGS liquefaction zones touch the bayside Redwood Shores district.
Soils. Alluvium and (in Redwood Shores) Bay Mud / engineered fill; geotech-driven foundation design standard.
Energy code & green building.
California Energy Commission Climate Zone 3. 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. Redwood City may layer reach-code or local green-building amendments — confirm the current adopted ordinance 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.
- Hillside
- R-1-H zoning in Emerald Hills adds slope-band density, retaining-wall height limits, and Architectural Review.
- Wildfire / WUI
- Western hillside parcels (above Emerald Hills) approach VHFHSZ-mapped areas; verify on the CAL FIRE FHSZ map.
- Flood
- Redwood Shores and bayside parcels are in FEMA SFHA — elevation certificates and freeboard requirements apply.
- Soils / foundation
- Alluvium and (in Redwood Shores) Bay Mud / engineered fill; geotech-driven foundation design standard.
- Site access / staging
- Site access in Redwood City can require temporary street-use or encroachment permits depending on street width, on-street parking restrictions, and proximity to schools or transit corridors.
Common risks: FEMA freeboard requirement raising finished floor late · R-1-H slope-band reducing buildable area · Bay Mud geotech requiring pile or ground-improvement
