Specialty shapes windows in San Francisco, California
Arches, circles, eyebrows, and custom geometric shapes — usually fixed. For San Francisco's older housing stock (77.2% of homes predate 1980), specialty shapes window replacement is a common project — and in the ENERGY STAR South-Central zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.
Short answer
Specialty shapes windows in San Francisco typically cost $775–$3,885+ installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Specialty shapes windows and San Francisco's climate
San Francisco sits in the ENERGY STAR South-Central zone (IECC zone 3C (warm, marine), San Francisco County), where the priority is a low SHGC (≤ 0.23) to block solar heat.
With no operable joints to leak, a specialty shapes window delivers the best whole-unit efficiency of any style — the easiest way to clear the South-Central-zone target of SHGC 0.23 or lower. Pair it with operable units where you need ventilation or bedroom egress.

What Specialty shapes windows cost in San Francisco
Specialty shapes window replacement in San Francisco runs $775–$3,885+ installed. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand. San Francisco is one of the most expensive window-replacement markets in the country, and the premium isn't just Bay Area labor rates. Pre-war buildings mean nonstandard opening sizes, ornate bay windows, and frequent custom fabrication rather than off-the-shelf units. If your building is a designated historic resource, matching requirements can push you toward wood or approved wood-clad frames, which cost meaningfully more than vinyl. Nearly every home here predates 1978, so lead-safe work practices under the EPA's RRP rule add prep and containment time. Permit fees from the Department of Building Inspection apply to every job, and Planning review — where still required — can add time and revisions. The 2025 rule change allowing vinyl on non-historic buildings should ease costs for many owners, but get any material assumptions confirmed against your building's historic status before you sign a contract.

Rebates & incentives in California
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
California's IRA rebates run through the California Energy Commission. The HEAR-funded HEEHRA program (delivered via TECH Clean California / The Switch Is On) launched for income-eligible households, but Phase I single-family rebates were fully reserved statewide as of early 2026, with a waitlist and a Phase II in design. HOMES funds are being routed into the Equitable Building Decarbonization Direct Install program and a Pay-for-Performance program that were not yet issuing rebates as of mid-2026. Confirm current availability first. See our San Francisco guide for the full program list.
