Redondo Beach Building & Safety sits at 415 Diamond Street, a short walk from the pier. We've been there enough times that the plan reviewers know us by name. That's not a sales pitch — that's a fact that matters when you're trying to predict how a new build will move through a city.
This post is about permits. Not framing, not finishes, not what the house should look like. Just the paperwork side: what the city wants, how long it takes, and which constraints on a Redondo Beach lot will reshape your design before a single shovel hits the dirt.
We're writing this for owners and architects who are about to submit a new single-family or duplex into Redondo, and for anyone who's already submitted and is wondering why the corrections list is longer than they expected. The short version: it's a coastal city with real wind loads, real height limits, and a counter that reads plans carefully. Plan accordingly.
The Counter at 415 Diamond Street
The building department is at 415 Diamond St, Redondo Beach CA 90277. Phone is (310) 318-0637. Hours are Mon–Thu 7:30am–5:30pm, alternate Fridays. That alternate-Friday schedule trips people up. If you're driving down from somewhere else to submit, call first.
Typical plan-check duration is 4 to 8 weeks for a first review. That's first review only. You will get corrections back. Plan on a second review and sometimes a third before the permit is ready to issue.
Expedited review is available in Redondo Beach if your schedule justifies the cost. We've used it on projects where a financing window or an Edison coordination date drove the timeline. It does not skip the corrections process. It just moves your plans to the top of the stack faster.
What Drives the Corrections List
Four things show up on almost every new build correction letter in Redondo Beach. Knowing them in advance saves a review cycle.
First, the 30-foot height limit in R-1. Single-family parcels are capped at 30 feet, and the way height is measured matters. Average grade, top of ridge, parapet heights — all of it gets checked against a benchmark, and a half-foot mistake costs you a resubmittal.
Second, lot coverage. Most R-1 parcels carry a 50% lot coverage limit. Garages, covered patios, and second-story overhangs all count differently. Read the zoning section before you finalize the footprint.
Third, off-street parking. Off-street parking is required for all new bedrooms. Add a bedroom in design, add a parking space. That cascades into garage sizing and driveway geometry fast.
Fourth, the Hollywood Riviera architectural review. Some streets in the Riviera carry design covenants on visible changes. If your lot is one of them, build the review timeline into your schedule. We've seen Riviera review add four to eight weeks on top of plan check.
Code References That Matter
A new single-family build in Redondo lands under the California Residential Code (CRC) for framing, plumbing, mechanical, and electrical. Duplexes also fall under CRC. Anything 3+ units jumps to the California Building Code (CBC), which is a different review path and a different fee structure.
Title 24 Part 6 governs energy. The 2022 cycle is currently in effect, with the 2025 cycle phasing in. Title 24 Part 11 (CALGreen) is the mandatory baseline for all new construction. Your Title 24 envelope calculations need to be coordinated with HVAC design at the framing stage, not after. That's one of the most common pitfalls we see on new builds.
For wind and seismic, ASCE 7 applies. Redondo Beach is firmly inside Exposure D within roughly 0.5 mile of the coast. King Harbor area carries full coastal wind load. That changes shear wall layouts, hold-down sizing, and roof attachment details. Don't let an out-of-area engineer assume Exposure C — the city will catch it.
The Soft Costs People Forget
We don't publish construction prices on this blog, but the city does publish permit fees and they're worth reading before you submit. For remodels under $50k of valuation, Redondo lists the fee as "1.1% of valuation + $165 plan check" with a TODO to verify. New builds use a separate valuation schedule, but the structure is similar — a percentage of valuation plus a plan-check fee.
The cost people actually forget isn't the city fee. It's the Edison service upgrade. Single-family panel upgrades often run 8 to 14 weeks from utility application to energization. If you're going from a 100-amp legacy panel to a 200- or 400-amp service for a new build with EV charging and an all-electric kitchen, start that application the day you submit to plan check. Do not wait until framing.
The other soft cost is the soils report. On harbor-adjacent lots and any second-story addition over fill, a geotech report is functionally required. The city won't always demand it at intake, but the structural reviewer will. Get it done before structural plan check or you'll lose a cycle.
How We Sequence a Redondo New Build
Our standard sequence on a Redondo new build runs roughly like this. Schematic design and zoning verification first, including height, coverage, and parking. Then construction documents with structural engineering keyed to ASCE 7 Exposure D and Title 24 envelope calcs locked in.
Submit to 415 Diamond. Concurrently, file the Edison service application and order the soils report if the lot warrants it. First plan check returns in 4 to 8 weeks. We address corrections, resubmit, and typically issue within 10 to 14 weeks of first submittal on a clean project.
You can see how this plays out in built work. Our South Redondo Triplex ran through this process as a multi-unit project, which kicked it into CBC territory and added review depth. The Redondo Beach Custom Home was a CRC path, single-family, full coastal wind loading.
What This Means for Your Schedule
A realistic new-build timeline in Redondo, permits included, is in the 40-to-78-week range from kickoff to occupancy. Permits themselves are 10 to 20 weeks of that, depending on review cycles and whether Riviera architectural review is in play.
If someone tells you they can permit a new build in Redondo in four weeks, ask them what they're skipping. The honest answer is that the counter is fair but thorough, and the constraints — height, coverage, wind exposure, parking — are real. Design to them up front and the process is predictable. Fight them and the process is not.
FAQ
How long does plan check take for a new single-family home in Redondo Beach? The city publishes 4 to 8 weeks for typical plan check. First review only. Expect a corrections cycle and a resubmittal.
Is expedited plan check worth it? Sometimes. Expedited review is available in Redondo, and we've used it when financing or utility coordination drove the schedule. It doesn't eliminate corrections, but it shortens the queue time between cycles.
Do I need a soils report for a new build? On most lots, yes — especially harbor-adjacent parcels or anywhere there's fill. The structural reviewer will ask for it. Get it before you submit.
What's the height limit? 30 feet in R-1 single-family. Measured carefully. Don't assume — verify against the city's measurement method.
When should I apply for the Edison service upgrade? The day you submit to plan check, at the latest. Lead times run 8 to 14 weeks from application to energization, and you do not want to be waiting on Edison at finish stage.
