Hermosa Beach is barely a mile deep from the Strand to the eastern city line. That single fact drives almost every schedule decision on a new build here. Salt air, Exposure D wind, a Coastal Zone that covers most of the parcels west of PCH, and lots that average about 2,700 sq ft mean the calendar is set by permits and site access as much as by framing crews.
We have been building in this city for decades, and clients almost always ask the same question first. How long from signed drawings to keys? The honest answer is a range. Our typical new-build timeline runs 40 to 78 weeks from design kickoff to certificate of occupancy, and where a Hermosa project lands in that band depends on four things: the Coastal Development Permit, the concurrent plan review at 1315 Valley Dr, Edison service coordination, and the physical constraints of the lot.
Here is how we sequence it.
Weeks 1 to 12: Feasibility, Design, and the Coastal Question
The first thing we do before anyone draws a floor plan is confirm which permit stream applies. Much of the city lies in the Coastal Zone, and a Coastal Development Permit may be required, including where a project increases height by more than 10% or affects coastal resources. That single determination can add months. If the project needs a CDP with a public hearing, we plan for it early instead of running into it at submittal.
Zoning envelope work happens in parallel. The 30 ft maximum height applies in most residential zones, and the Planning Commission may allow up to 35 ft only in unique circumstances where all abutting properties already exceed 30 ft. On a 2,100 sq ft lot the allowed coverage is 70%, which changes what a two-story program actually looks like on paper.
Schematic design, structural coordination with the geotech, and Title 24 envelope calcs all happen in this window. The energy calcs must be coordinated with HVAC design at framing stage, not afterthought. Getting the mechanical designer in the room during schematic saves a redesign loop later.
Weeks 10 to 14: Soils, Survey, and Pre-Submittal
The soils report is often the gating item. On the Hermosa Hills lots and anywhere with meaningful excavation, we need it before structural plan check. A boundary and topographic survey runs alongside. Neither is expensive relative to the whole job, and both prevent expensive surprises.
We use this window for a pre-submittal conversation with the Community Development Department, reachable at (310) 318-0242. A 20-minute call before you print drawings saves weeks. The building permit counter runs 7:00 to 8:30am and 4:30 to 6:00pm, Monday through Thursday, so we plan counter trips around those windows.
Weeks 14 to 30: Plan Check
Here is where Hermosa differs from most South Bay cities. The city runs concurrent plan review, meaning Planning, Building and Public Works review a submittal at the same time rather than in sequence. That helps. What it does not do is guarantee a turnaround, because Hermosa Beach does not publish a plan check timeline.
Our working assumption on a clean single-family submittal is a first-round comment set in 4 to 8 weeks. Comment responses take us 2 to 4 weeks depending on scope. A second round comes back faster. Two rounds is typical, three is not unusual on complex coastal or hillside projects.
If a Coastal Development Permit is required through the Planning Commission or the Coastal Commission, add 8 to 20 weeks to this phase and plan a hearing. We front-load the drawings on those projects so we are not chasing corrections between hearings.
Weeks 20 to 34: Edison and Utility Coordination
We file the Edison service application the day we submit for plan check. Not later. Single-family panel upgrades often run 8 to 14 weeks from utility application to energization, and on a new service the timeline can be longer. If the transformer needs an upgrade or a new pull, you can lose a month at rough-in waiting for a meter.
Sewer lateral capacity is worth checking during this same window. Older Hermosa lots may need lateral replacement, and Public Works has a say in the encroachment permit for any work in the street.
Weeks 30 to 70: Construction
Permits in hand, we mobilize. On a Strand or walk-street lot, the access and staging plan drives the schedule more than the framing sequence does. There is no room for a dumpster in front of a walk-street house because there is no street. Material deliveries get scheduled by the hour, not the day, and lifts get planned around neighbors.
For a straightforward two-story single-family on a standard interior lot, we plan 32 to 40 weeks of construction. Foundation and rough framing runs 10 to 14 weeks. MEP rough, insulation, drywall, and exterior envelope take another 12 to 16 weeks. Finishes, cabinetry, tile, hardwood, and site work fill the last 10 to 14. Coastal exposure means we specify marine-grade stainless fasteners west of Sepulveda and Hardie panel with smooth-finish stucco to hold up.
Weather adds a wildcard. Rainfall averages 13.2 inches a year, most of it between December and March, and May Gray and June Gloom compress the exterior paint window. We schedule stucco and exterior finishes to land outside those windows when we can.

Weeks 70 to 78: Inspections, Punch, and COO
Final inspections in Hermosa are straightforward if the rough inspections were clean. Building final, Planning sign-off on any coastal or zoning conditions, Public Works sign-off on any street work, and the fire clearance for WUI assemblies where mapped. Cal-Fire Chapter 7A applies in mapped fire severity zones and drives the roof assembly, vent specs, and exterior wall requirements.
Punch list runs 2 to 4 weeks. Certificate of Occupancy issues once all corrections are cleared and the final inspection card is signed. Move-in follows.
FAQ
Do I need a Coastal Development Permit for a new single-family home in Hermosa? It depends on the parcel and the scope. Much of the city is in the Coastal Zone, and a CDP may be required if the project increases height by more than 10% or affects coastal resources. We confirm this in the first two weeks of feasibility.
How long does Hermosa Beach plan check take? The city does not publish a turnaround. Our working assumption on a clean single-family submittal is a first-round comment set in 4 to 8 weeks, with two rounds typical before approval. Concurrent review across Planning, Building, and Public Works helps compress the calendar.
What is the height limit? 30 ft in the zones where it applies. The Planning Commission may allow up to 35 ft only in unique circumstances where all abutting properties already exceed 30 ft. Do not design to 35 ft on the assumption you will get relief.
When should we call Edison? The day plans are submitted for permit. Panel upgrades run 8 to 14 weeks and new services can take longer. Waiting until framing is the number one cause of a stalled rough-in.
What code cycle applies right now? Title 24 Part 6 (energy) 2022 cycle is currently in effect, with the 2025 cycle phasing in. CALGreen Part 11 is the mandatory baseline for all new construction. We design to the cycle in effect at permit submittal.
