3. Custom Built-In: Integrating a drawer microwave into new or existing cabinets, often part of a larger kitchen remodel.
• Countertop Replacement: $150 – $350
• Over-the-Range Retrofit: $750 – $1,500
• Custom Built-In: $1,400 – $3,200

1. Electrical Capacity
Many pre-1950s Victorians run on 60-amp panels. Upgrading to a dedicated 20-amp circuit adds $400 – $900. CountBricks voice estimates automatically flag undersized panels and insert the correct allowance.
2. Venting Requirements
Over-the-range units need a 3¼" x 10" or 6" round duct to the exterior. In multi-unit buildings, condo HOAs may restrict penetrations, driving up costs for recirculating filter kits—budget an extra $125.
3. Cabinet Modifications
San Francisco’s diverse architecture means custom sizes. Shaving face frames, adding fillers, or building a microwave shelf can add 4–8 labor hours. CountBricks blueprint AI calculates those carpentry hours from uploaded PDFs.
• Measure twice, order once: San Francisco return freight charges can exceed $150 for oversized appliances.
• Confirm HOA rules before cutting vent holes to avoid costly fines.
• Use low-profile ducts in shallow Victorian walls to meet code without compromising plaster.
• Schedule electrical and carpentry on the same day to reduce parking permit fees.
• Generate your permit packet through CountBricks.com/portfolio templates to speed approval.
