Luxury Remodeling Investment Guide
— Marin County
Transparent pricing ranges for every project. Fixed-scope contracts. No surprises.
Pricing transparency is the number one complaint homeowners have about the construction industry. Custom work means no flat rate — every site, every scope, every finish level is different. What we can guarantee is this: the number in our fixed-scope contract is the number you pay. No change orders that weren't owner-directed. No last-minute surprises at closeout.
We also use PlanPass.ai — our proprietary AI tool that pre-analyzes permit risk before a shovel goes in the ground. Permit complications are where most Marin projects blow their budgets. PlanPass.ai eliminates that variable, so the number you approve is the number that arrives at the finish line.

Cost Factors
What Drives Your Investment
Permit Complexity
Marin County permitting is among the most demanding in California. Each project requires jurisdiction-specific filings, fire district coordination, and setback analysis. ConstruBay's PlanPass.ai pre-analyzes permit risk before the first dollar is spent — eliminating the building department surprises that derail most projects.
Material Level
The difference between a $95,000 kitchen and a $175,000 kitchen is largely materials — custom cabinetry versus stock, quartzite versus quartz, Sub-Zero versus standard appliances. We source to your finish level and lock it in writing before construction begins.
Structural Scope
Opening walls, relocating load-bearing elements, or adding square footage adds engineering, structural reports, and additional permit requirements. We identify structural scope in the proposal phase — not during demolition.

Client Perspective
“Paulo presented a fixed-scope contract on day one and held to every number. The final invoice matched the proposal exactly. After two previous contractors who never delivered that, it changed how we think about building.”
