THE WORK, EXPLAINED
Start with the condition.
Understand the scope.
Clarify whether the proposal replaces the sashes, installs an insert or removes the complete frame. Ask which balances, locks and other hardware are included and whether any existing components remain. Agree on the finishing scope and a completion check covering the operation of both sashes and the selected tilt features, where fitted.
What may be involved
- double-hung frame
- upper sash
- lower sash
- balances
- meeting-rail lock
- weather seals
- installation trim
Ask the provider to distinguish existing parts to inspect, proposed replacements, and tools, materials or reports included in the service. Confirm the work and exclusions after assessment; this list does not mean that every item will be supplied or replaced.
LOCAL RESEARCH / Visitacion Valley
Housing context
Planning identifies this area among neighborhoods containing RH-1 one-family residential zoning, so individual-home hardware is part of the local mix.
Source ↗Local context
Planning recorded 170 completed new housing units in 2025, so newer residential systems are part of the current building mix.
Source ↗Planning your work
San Francisco's Department of Building Inspection publishes step-by-step instructions for over-the-counter permits covering doors, windows, reroofing and other common exterior residential projects. The page lists in-kind window replacement and in-kind exterior door replacement, at the same size and location, among the projects eligible for over-the-counter review through the PermitSF portal, and separately says that new windows or exterior doors in new locations are among the projects that need plans. Read it before agreeing a scope, and confirm the address, the opening and the review route with the department. It does not decide eligibility, timing or requirements for an individual property.
Source ↗Area-wide context does not establish the condition of your property or equipment.
Before the visit
