The Short Answer
YES — California Building Code requires a permit for window replacement when the existing rough opening is altered or structural headers are modified; Daly City's Building Division also requires permits for like-for-like replacements to enforce Title 24 energy compliance documentation.

How window replacement permits work in Daly

The permit itself is typically called the Residential Building Permit — Window/Door Replacement.

This is primarily a building permit. You'll be working with one permit, one set of inspections, and one fee schedule.

Why window replacement permits look the way they do in Daly

Daly City's Doelger-era row houses (1940s-60s) sit on expansive hillside fill and require soils/geotechnical reports for most foundation work. Soft-story condo buildings along Junipero Serra Blvd face seismic retrofit pressure under San Mateo County regional hazard programs. Many parcels in western Daly City (Westlake) fall in mapped landslide hazard zones requiring grading permits even for modest landscaping work.

For window replacement work specifically, energy code and U-factor requirements depend on local conditions: the city sits in IECC climate zone CZ3C, design temperatures range from 38°F (heating) to 73°F (cooling).

Natural hazard overlays in this jurisdiction include earthquake seismic design category D, landslide, fog driven wind, liquefaction zones, and FEMA flood zones. If your address falls within any of these overlay zones, the window replacement permit application picks up an extra review step that can add days to the timeline and specific design requirements to the plans.

HOA prevalence in Daly is medium. For window replacement projects this matters because HOA architectural review committee approval is a separate process from the city building permit, and the two have completely different rules. The HOA reviews materials, colors, and aesthetics; the city reviews structural, electrical, and code compliance. You generally need both, and the HOA approval typically takes 2-4 weeks regardless of how fast the city is.

Daly City has limited formal historic districts; no large National Register districts. Some older Westlake and Mission Hills neighborhoods have aesthetic guidelines but no citywide historic preservation overlay requiring Architectural Review Board approval for routine permits.

What a window replacement permit costs in Daly

Permit fees for window replacement work in Daly typically run $150 to $600. Valuation-based; Daly City typically uses ICC BVD table valuation for fenestration work, with a minimum permit fee plus a plan check fee typically 65–80% of the permit fee

A separate California Building Standards Commission (CBSC) state surcharge (currently $4 per $100,000 of valuation, minimum $1) is added at issuance; Daly City also charges a technology/records fee.

The fee schedule isn't usually what makes window replacement permits expensive in Daly. The real cost variables are situational. Custom window sizing required for non-standard Doelger-era rough openings — off-the-shelf windows rarely fit, adding 20–40% over stock pricing. California Title 24 CZ3C SHGC ≤0.25 requirement limits window selection and often mandates premium low-e glass packages not stocked locally. Stucco patching and re-texturing at exterior after removal of old aluminum frames — Daly City's persistent coastal fog means improperly patched stucco fails quickly, requiring skilled finish work. Structural engineering letter if any rough opening is modified in seismic zone SDC-D bearing-wall construction.

How long window replacement permit review takes in Daly

5-10 business days for standard plan check; over-the-counter same-day review sometimes available for straightforward like-for-like replacements with complete Title 24 CF1R documentation. For very simple scopes, an over-the-counter same-day approval is sometimes possible at counter-staff discretion. Anything with structural elements, plan review, or trade subcodes goes into the standard review queue.

The clock typically starts when the application is logged in as complete (not when it's submitted), so missing documents reset the timer. If your application gets bounced for corrections, you're generally back at the end of the queue rather than the front.

Documents you submit with the application

For a window replacement permit application to be accepted by Daly intake, the submission needs the documents below. An incomplete package is returned without going into the review queue at all.

Who is allowed to pull the permit

Homeowner on owner-occupied | Licensed contractor only | Either with restrictions — California B&P Code §7044 allows owner-builders on owner-occupied single-family residences; homeowner must sign owner-builder declaration and cannot sell within 1 year without disclosure

California CSLB Class B (General Building) or C-17 (Glazing) license required for contracts over $500 in labor and materials; verify at cslb.ca.gov

What inspectors actually check on a window replacement job

A window replacement project in Daly typically goes through 4 inspections. Each inspector has a specific checklist, and the difference between a same-day pass and a re-inspection (which costs typically $75–$250 in re-inspection fees plus another scheduling delay) usually comes down to one or two items on these lists.

Inspection stageWhat the inspector checks
Rough / Framing InspectionHeader size and bearing, rough opening dimensions, shear panel continuity if existing stucco was cut, proper nailing of rough sill and king studs
Waterproofing / Flashing InspectionSelf-adhered flashing at sill, head, and jambs; integration with existing exterior stucco lath or weather-resistant barrier; no exposed gaps in Daly City's fog-driven coastal moisture environment
Energy Compliance InspectionNFRC label on installed unit matches approved CF1R documents; U-factor and SHGC sticker present and legible; proper installation per manufacturer specs
Final InspectionEgress compliance for bedroom windows, operation of hardware, interior trim, stucco patch quality at exterior, and sign-off on Title 24 CF6R installation certificate

If an inspection fails, the inspector leaves a correction notice with the specific items to fix. You make the corrections, schedule a re-inspection, and the work cannot proceed past that stage until it passes. For window replacement jobs in particular, failing the rough-in inspection means tearing back open work that was just covered.

The most common reasons applications get rejected here

The Daly permit office sees the same patterns over and over. These specific issues account for most first-pass rejections, and most of them are entirely preventable with a few minutes of double-checking before submission.

Mistakes homeowners commonly make on window replacement permits in Daly

The patterns below come up over and over with first-time window replacement applicants in Daly. Most of them are rooted in assumptions that work fine in other jurisdictions but don't here.

The specific codes that govern this work

If the inspector cites a code section, this is the list they'll most likely be referencing. These are the live code references that Daly permits and inspections are evaluated against.

California adopts its own Title 24 energy code which supersedes IECC; CZ3C SHGC ≤0.25 is more restrictive than base IECC. Daly City is in a Seismic Design Category D zone — if header or rough opening is modified, shear wall continuity must be maintained per CBC seismic provisions.

Three real window replacement scenarios in Daly

What the rules look like in practice depends a lot on the specific situation. These three scenarios cover the common shapes of window replacement projects in Daly and what the permit path looks like for each.

Scenario A · COMMON
Classic Doelger row house in Westlake with original 1950s aluminum single-pane sliders
Rough openings are non-standard at 57.5" wide, requiring custom vinyl frames; Title 24 CZ3C SHGC ≤0.25 eliminates most stock low-e options, adding 3–4 week lead time and $300–$600 per unit in custom upcharge.
Scenario B · EDGE CASE
1960s Mission Hills stucco home on a mapped hillside landslide zone
Homeowner wants to enlarge a bedroom window for egress compliance, but enlarging the rough opening in the original bearing wall requires a structural engineer's letter for the modified header in SDC-D, adding $800–$1,500 to project cost.
Scenario C · COMPLEX
Second-floor bedroom window in a Daly City soft-story condo near Junipero Serra Blvd
Condo association CC&Rs require board approval for any exterior change, HOA review adds 4–8 weeks before permit can even be submitted, and the replacement unit must match existing exterior profile per HOA aesthetic guidelines.
