New construction in Berkeley.
New construction in Berkeley is constrained by the Hayward Fault directly under the eastern hills, an all-electric reach code that removes gas from new homes, and rigorous ZAB review on view-corridor parcels — a unique stack you will not find together elsewhere in the East Bay.
Hillside customs above the UC campus, flatland R-1 rebuilds, and small-scale missing-middle infill enabled by recent zoning reforms.

New single-family permits in Berkeley are issued by City of Berkeley Permit Service Center — Building & Safety Division; California Title 24 Part 6 and CALGreen Part 11 apply statewide on top of any Berkeley reach-code amendments.
“Plan the project all-electric from day one and pull a CGS EQ Zone App report early. A hillside parcel above Tilden almost certainly triggers both Alquist-Priolo design and Chapter 7A construction, which materially shifts foundation, framing, and exterior assemblies.”
What gets built in Berkeley.
- ▸Elmwood R-1 craftsman teardown-rebuild
- ▸Berkeley Hills hillside custom
- ▸Missing-middle small multifamily on a converted SFR lot
Does the lot work?
Buildable envelope is constrained by Berkeley's strict average-grade and daylight-plane rules; hillside parcels add slope-band density and view-preservation considerations.
Zoning and entitlement.
Berkeley's zoning ordinance is being rewritten under the Missing Middle initiative; R-1, R-1H (hillside), and R-2 carry distinct setback, height, and unit-count rules — confirm the adopted version at intake.
Many R-1 projects can clear ministerial review; Zoning Adjustments Board (ZAB) approval is common for height/setback variances and any project visible from designated view corridors.
Jurisdiction & plan check.
New homes in Berkeley are permitted by City of Berkeley Permit Service Center — Building & Safety Division.
Plan check is rigorous on Title 24, structural lateral design, and the city's adopted electrification reach code; expect 2–3 comment cycles on most custom SFRs.
City of Berkeley Permit Service Center — Building & Safety Division schedules inspections through its permit portal; foundation, framing, rough trades, insulation, drywall, and final are the standard hold points for new SFRs in Berkeley.
What drives cost in Berkeley.
Cost in Berkeley reflects local labor, land, and code conditions. The drivers below have the largest schedule and budget impact on ground-up homes here.
- $All-electric mechanical and water-heating equipment
- $Electrical service upsize (200A → 400A) for full-electric load
- $Hillside grading, shoring, and retaining walls
- $Chapter 7A ignition-resistant assemblies above the hill line
- $ZAB-driven story-pole noticing and design revisions
What drives schedule in Berkeley.
- ◷ZAB scheduling on view-corridor projects
- ◷Story-pole installation and noticing window
- ◷Alquist-Priolo geotech review
- ◷PG&E electrical-service upsize lead time
Sitework & utilities.
Grading & drainage. Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Berkeley Permit Service Center — Building & Safety Division; sloped parcels require geotech and an erosion-control plan.
Utility upgrades. PG&E electric/gas; EBMUD water and sewer; Berkeley's all-electric reach code commonly removes gas-service work but adds electrical-service upsize.
Sewer / septic. Municipal sewer service in developed Berkeley parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping.
Site access & staging. Site access in Berkeley 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 Hayward Fault Alquist-Priolo zone runs through the eastern hills — a primary design constraint for any hillside custom; CGS liquefaction zones cover parts of the flats near the Bay.
Soils. Hill parcels sit on Franciscan bedrock or residual clay; flatland parcels include alluvium and (near the Bay) Bay Mud and engineered fill.
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. Berkeley has adopted an all-electric reach code for most new construction; verify current scope and exemptions 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-1H hillside zoning adds slope-based density limits, story-pole noticing, and stricter grading rules; portions of the upper hills are also in CAL FIRE VHFHSZ.
- Wildfire / WUI
- Upper Berkeley Hills (above Grizzly Peak Boulevard and into Tilden) sit in Very-High Fire Hazard Severity Zone — Chapter 7A applies.
- Soils / foundation
- Hill parcels sit on Franciscan bedrock or residual clay; flatland parcels include alluvium and (near the Bay) Bay Mud and engineered fill.
- Site access / staging
- Site access in Berkeley 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: Alquist-Priolo trench requirement late in design · All-electric scope misread leaving gas piping in late drawings · Story-pole opposition triggering redesign

Why Berkeley isn’t like the next city over.
Hayward Fault Alquist-Priolo across the hills + city-wide all-electric reach code + ZAB design review on view-corridor parcels.
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 Berkeley Permit Service Center — Building & Safety 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.
Berkeley new construction · FAQ.
- Does Berkeley require all-electric new homes?
- Berkeley has adopted an all-electric reach code for most new construction with limited exceptions; verify current scope with the Permit Service Center at intake.
- Is my Berkeley lot in an Alquist-Priolo fault zone?
- Use the California Geological Survey EQ Zone App. The Hayward Fault zone runs the length of the eastern hills and constrains foundation design and trenching requirements.
- Does Chapter 7A apply to my Berkeley Hills project?
- If the parcel is mapped Very-High Fire Hazard Severity Zone (common above Grizzly Peak), yes — Chapter 7A ignition-resistant exterior assemblies apply.
- When does my project go to ZAB?
- Variances, design-review triggers, and projects in designated view corridors typically require Zoning Adjustments Board approval; staff can confirm on a pre-application review.
- Does CALGreen apply?
- Yes, statewide — CALGreen Part 11 mandatory measures plus Berkeley's local green-building amendments.
