Window Replacementin Manhattan Beach, CA
Window replacement in Manhattan Beach is covered by federal lead-safe rules in any home built before 1978, and the City's own code names window replacement as remodeling that needs a City permit. About 59 percent of homes predate 1980. Coastal-zone and design-overlay lots may add review, so describe your scope to the City before you order.
Manhattan Beach filled in fast. The Census counted 6,398 people in 1940, 17,330 in 1950 and 33,934 in 1960, and the 2024 five-year estimates show 3,416 of its 15,281 homes, 22.4 percent, built in the 1950s. About 7.5 percent date from 1939 or earlier, and 59.1 percent predate 1980. Any original window in those houses is old enough to carry lead paint on its frame, which sets the first rule of this page.
Below we cover the lead rule, the permit wording in the City's code, the Coastal Zone, Gaslamp and historic reviews, changing an opening, the glass and energy questions we could not settle, and how an install day runs. The City's website refused our tools, so the Municipal Code text comes from GoCodebook and Zoneomics mirrors of the 2022 edition, and a 2025 update is unconfirmed. Confirm anything that matters with Building and Safety. Price ranges and phases are on our windows page.
Manhattan Beach Building and Safety and Planning rules that apply to window work
Where windows permits come from in Manhattan Beach: City of Manhattan Beach Community Development Department, Building and Safety Division.
- Window replacement is named, with roof replacement and patio construction, as remodeling that needs a City permit in the City's definition of construction activity (Municipal Code 9.44.010). Bay windows may project into required yards only if at least 50 percent of the vertical surfaces are glass, no longer than 8 feet at the setback line, and no more than a quarter of the buildable length or width in aggregate per level (Municipal Code 10.60.040(F)).
- On a historic resource, repair or replacement of windows, siding, roofs, chimneys, accessory structures or fences with materials of the same kind, type and texture already in use can be approved administratively by the Director as a certificate of appropriateness; other window changes go to the Planning Commission (Municipal Code 10.86.150).
- EPA's lead rule always covers window replacement in housing built before 1978, whatever the square footage; the Census 2020 to 2024 estimate is that about 59 percent of Manhattan Beach housing units were built before 1980.
- CSLB defines the C-17 Glazing classification as a contractor who selects, cuts, assembles or installs glass, glass work, mirrored glass and glass substitute materials, and fabricates and glazes frames, panels, sashes and doors.
Lead-safe window replacement in a Manhattan Beach home built before 1978
This is the one firm rule. EPA's Renovation, Repair and Painting rule requires anyone paid to disturb paint in housing built before 1978, sole proprietors included, to be certified and to use lead-safe work practices. Minor repair is exempt only at 6 square feet or less of paint per room inside or 20 square feet or less outside, and window replacement is always covered, whatever the size of the job.
In Manhattan Beach the odds favor the rule: 59.1 percent of homes were built before 1980, and the estimated median year built is 1970. Ask the installer for the certification, how the work area is sealed and how sashes and trim are removed and bagged.
Age adds a second reason to ask questions. The Census count shows 1,145 homes built in 1939 or earlier and 1,139 more from the 1940s, so a good share of the windows in older streets may be original wood sashes with many coats of paint. Sealed, repainted and stuck windows are a different decision from a failed one, and a contractor who quotes a whole-house replacement without opening a single sash is guessing. Ask for a window-by-window list that says which frames stay, which are repaired and which are replaced.
- Is the firm EPA lead-safe certified, and can it show the certificate?
- How are the room and the floor protected during removal?
- Who cleans up, and how is the debris bagged and hauled off?
Does window replacement need a permit in Manhattan Beach, even a same-size swap?
Plan on one. Municipal Code 9.44.010 defines construction activity to cover remodeling that needs a City permit and names window replacement, along with roof replacement and patio construction, as examples. That is the clearest wording we found. The City's permit pages were closed to our tools, so we cannot say whether it offers a quick over-the-counter path for a same-size, same-type change, as Los Angeles does. Ask which route applies to your address.
Whoever pulls the permit needs a valid contractor's license in the trade and proof of workers' compensation under 9.04.010, unless an owner-builder qualifies under Business and Professions Code 7044. CSLB's glazing class, C-17, covers selecting, cutting, assembling and installing glass and fabricating and glazing frames, panels, sashes and doors. It does not name windows outright, so the license that fits a given window job is a question for the contractor and the City.
California allows an unlicensed person to take minor work of $1,000 or less, but not if a permit is required or a worker is hired. Starting without a permit adds a fee set by the Building Official plus an investigation fee of up to the permit fee.
Windows near the beach and on older streets: Coastal Zone, Gaslamp review and historic homes
Three layers can sit on top of the base zone. The Coastal Zone covers the western edge of the city, 17 of 114 points in our sample, and development there needs a Coastal Development Permit unless an exemption applies. We could not read the exemption list. We say only that coastal-zone work may need coastal review, and you should ask before you assume a window swap is exempt.
The D3 Design Overlay covers the Gaslamp neighborhood and adds special design standards and review. Other D overlays, D1 to D8, touch other corridors, and the code text does not list parcels, so each address has to be checked on the zoning map.
On a historic resource, repair or replacement of windows with materials of the same kind, type and texture already in use can be approved by the Director as a certificate of appropriateness. Other window changes go to the Planning Commission (10.86.150). We did not find the City's register, so we make no claim about any particular street.
Changing a window opening: bay windows, larger glass and the setback rules
A replacement in the same opening is one job, and a new or bigger opening is another, because it changes the wall. We found no sourced threshold for when the City asks for plans, so describe the change on the call. Bedroom egress sizes and tempered-glass locations are in the building code, and we did not read those sections, so we print no dimensions.
One projection rule is clear. Under Municipal Code 10.60.040(F), bay windows may extend into required yards only if at least 50 percent of the vertical surfaces are glass, they are no longer than 8 feet at the setback line, and together they take up no more than a quarter of the buildable length or width on a level. Side setbacks are 10 percent of lot width with a 3 foot minimum, which is tight on narrow lots.
Anything that adds height is a different job. The 26 foot and 30 foot limits and the way height is measured are voter-protected, so a design that grows taller cannot be rescued by an exception.
Glass labels, frames and energy rules: what we could and could not confirm
We read no adopted values for U-factor or solar heat gain, because city handouts disagree and the 2025 Energy Code took effect statewide on January 1, 2026, while the local text on the mirror still shows the 2022 edition. Ask for windows with an NFRC label that meet Title 24 Part 6 for your climate zone, and ask the City which edition it applies to your permit. In Los Angeles, dual glazing certified by the National Fenestration Rating Council is required for replacements. We have not confirmed that Manhattan Beach states it the same way.
Climate sets the stakes. NOAA's normals for the airport station show average highs from 65.6 F in February to 76.7 F in August, only 4.8 days a year above 90 F and 12.23 inches of rain, so cooling loads are mild. We found no sourced savings figure for the city and will not invent one.
The federal 25C Energy Efficient Home Improvement Credit is not allowed for property placed in service after December 31, 2025, according to the IRS, although many older pages still advertise it. Los Angeles County's copy of the state fire map put all 114 sample points in non-wildland areas, so we found no fire-zone glazing package here.
Lead times, noise hours and install day for windows in Manhattan Beach
Custom windows are built to order, and 4 to 8 weeks from order to delivery is a safe planning figure, followed by 1 to 3 days of installation and another 1 to 3 days of stucco and trim repair. Window replacement counts as construction activity here, so work stays inside 7:30 a.m. to 6:00 p.m. on weekdays and 9:00 a.m. to 6:00 p.m. on Saturdays, with nothing on Sundays or City holidays. Delivery trucks that idle or unload count too.
A delivery or dumpster over the public right-of-way needs a temporary encroachment permit unless it lasts under 2 hours with no street, lane or sidewalk closure. If your window permit lands in Area Districts III or IV, the Construction Management and Parking Plan and the 10 day notice to neighbors within 100 feet also apply, although the Director can waive items that do not fit a small job.
As MDG Builders, CSLB #1040337, we measure, order and manage the job, and a licensed glazing and installation firm sets the windows. Ask for the firm's license number and certificate of insurance. Our post on how general contractors use subcontractors explains the chain of responsibility.

What windows costs around Manhattan Beach
The windows page values vinyl replacement at about $550 to $1,200 per window installed and a whole house of 10 to 15 windows at about $14,000 to $28,000, with wood and fiberglass costing more. Three Los Angeles sources bracket those numbers: the 2025 Cost vs. Value report from Remodeling magazine, with vinyl at $23,783 and wood at $27,913 and resale recovery of about 83.2 and 81.9 percent; Angi's July 2026 average of $19,356; and a ConsumerAffairs page that gives no cost method. None is a Manhattan Beach quote, and Manhattan Beach's median home value is top-coded at $2,000,000 or more, so the resale percentages are only a regional guide. The license check guide explains how to verify the firm. Nearby cities set their own rules, so compare window replacement in Redondo Beach, Torrance, Hawthorne and Los Angeles. Windows in a new room go on our Manhattan Beach room addition page, a bath window on the Manhattan Beach bathroom page, a backyard unit on the Manhattan Beach ADU page, and the Manhattan Beach area page lists every trade we cover in the city.

Manhattan Beach window replacement questions, answered
Do I need a permit to replace windows in Manhattan Beach?
Plan on one. The City's code defines construction activity as remodeling that needs a City permit and names window replacement as an example. Whether a same-size swap gets a quick over-the-counter review is not stated in the pages we could read, so ask Building and Safety before you order.
Do replacement windows need to be lead-safe in Manhattan Beach?
Yes in any home built before 1978. EPA's rule always covers window replacement in older housing, whatever the square footage, and requires certified firms and lead-safe work practices. About 59 percent of Manhattan Beach homes predate 1980, so ask any installer for the certification.
How much do replacement windows usually cost?
Expect roughly $550 to $1,200 per vinyl window installed and $14,000 to $28,000 for a whole house of 10 to 15 windows, more for wood or fiberglass. Three Los Angeles sources support those figures and none covers Manhattan Beach, so a measured written proposal sets the real price.
How long does it take for new windows to be installed?
Ordering takes 4 to 8 weeks, and installation takes 1 to 3 days for a typical house, plus 1 to 3 days for stucco and trim repair. Work must finish by 6:00 p.m. on weekdays and Saturdays and cannot happen on Sundays. Special sizes and finishes cause most delays.
Are double pane windows required in California?
Usually, for replacements, but we could not confirm Manhattan Beach's own wording. Los Angeles requires dual glazing certified by the National Fenestration Rating Council under Title 24 Part 6, and Manhattan Beach adopts the state Energy Code. Ask Building and Safety what your permit will require.
Which is better, replacement windows or new windows?
It depends on the frames. A retrofit insert goes into the existing frame, keeps stucco and trim intact and costs less, while a full-frame replacement removes the frame, allows flashing repairs and usually means stucco work. Rotted or lead-painted frames argue for full-frame. A site visit settles it.
Is replacing home windows worth it?
At resale, vinyl window replacement recovered about 83.2 percent of its cost in the 2025 Los Angeles Cost vs. Value report, and wood about 81.9 percent. We found no sourced energy savings figure for Manhattan Beach, where cooling needs are mild, so judge the job on comfort, noise and condition.
What size egress window is required in a bedroom?
The building code sets minimum size and sill height for bedroom egress windows, but we did not read those sections and will not print dimensions. A new or enlarged opening usually needs plans. Ask Building and Safety for the numbers that apply to your bedroom before you order any windows.
Do I need special fire-resistant windows in Manhattan Beach?
Probably not for wildfire. Los Angeles County's copy of the state fire map classed every point we sampled as non-wildland, so no Very High Fire Hazard Severity Zone turned up. Confirm a specific address on the CAL FIRE viewer, since a sample cannot clear every lot.
