We focus on projects that need a contractor: remodels, additions, new homes, water damage and larger repairs.

Thanks, we received your request and will be in touch.

The Scope

What ground-up construction involves.

A new building starts with the ground: soils, foundations, shoring and site utilities come before framing. San Francisco lots are tight, neighbors are close and streets are often steep or narrow, so delivery, staging and protection of neighboring properties get planned before the first excavation.

We price the complete scope in writing from your drawings, sequence the trades, manage inspections and run the project through closeout.

Site preparation, excavation and shoring
Foundations and structural frame
Weatherproofing, windows and exterior cladding
Mechanical, electrical, plumbing and fire protection systems
Insulation, drywall and interior finishes
Utility connections and site work
Inspections at each stage
Final walkthrough and closeout documents

What an addition involves.

An addition is a new building that has to be stitched into an old one. Foundations, framing, the existing exterior envelope, plumbing, electrical and mechanical systems all have to meet the new work, and the existing house is still being lived in or protected while it happens.

We work from your architect's plans and engineer's calculations, price the whole scope in writing, and manage the permits, inspections and sequencing.

Site protection and demolition at the connection points
Foundations and structural framing
Weatherproofing and tie-in to the existing building
Extension of plumbing, electrical and mechanical systems
Windows, doors, insulation and drywall
Interior finishes and exterior cladding to match
Inspections at each stage
Punch list and closeout documents

What an ADU project involves.

An ADU is a complete dwelling: its own kitchen, bathroom, egress, fire and energy compliance and, usually, its own utility connections. Converting space inside an existing building and building a new detached unit are different projects with different risks, and both are more involved than their square footage suggests.

We review the lot and the building, price the full scope in writing, and manage construction from permits through closeout.

Site and building review before design starts
Foundation or slab work, or structural upgrades for conversions
Framing, insulation, windows and doors
New kitchen and bathroom, with plumbing and electrical
Heating, ventilation and energy compliance
Fire-safety and egress requirements
Utility connections and site work
Inspections and closeout
