How to Choose a General Contractor: Your Pre-Hire Checklist

Marin County real estate carries some of the highest property values in California, and building or renovating at that level raises the stakes on who you hire. A contractor who does great work in a straightforward market might struggle with a hillside lot, a wildfire zone, or a design review board in Ross or Belvedere.

This checklist walks through what to verify before you sign anything: licensing, local permitting experience, communication process, portfolio, and contract terms. Work through it with any general contractor Marin County property owners are considering, and you’ll walk into that first meeting with real questions instead of a gut feeling.

Key Takeaways

• A California contractor’s license is the baseline, not the finish line. Local Marin experience matters just as much.
• Marin’s wildfire (WUI) rules and multi-town permitting process trip up contractors who haven’t worked in the county before.
• A true design-build contractor keeps one team accountable from design through construction, instead of passing you between an architect and a separate builder.
• References from comparable Marin projects tell you more than a polished portfolio site.
• The lowest bid is rarely the safest one. Get specific about what’s included before comparing prices.

Why Marin County Makes This Harder Than a Generic Checklist

Marin isn’t one uniform market. It’s a patchwork of incorporated towns (San Rafael, Mill Valley, Larkspur, and others) and unincorporated county land, each with its own permitting rules layered on top of state building code.

Add in hillside lots that need geotechnical review, wildfire hazard zones with some of the strictest exterior material rules in California, and design review boards in aesthetically protective communities, and it’s clear why local experience matters more here than in most markets.

A contractor who’s only worked in flatter, less regulated areas can still be a good builder. They may just not know what your specific address requires until it’s already causing delays.

Licensing, Bonding & Insurance

Confirm the basics first. This part is non-negotiable no matter where you’re building.

• Active CA contractor’s license. Confirm it’s current and in good standing on the CSLB (Contractors State License Board) website. Holly Construction’s own license, CA #757136, is a good example of what to look for.
• General liability insurance. Coverage should match the size and value of your project.
• Workers’ compensation. Required for every employee, and worth verifying for subcontractors too.
• Appropriate bonding. Ask what bond level applies to a project your size.
• A clean disciplinary record. The CSLB site shows any complaints or actions on file.

Pro tip: Ask for the license number in writing, then look it up yourself. Don’t take a business card’s word for it.

Local Permitting & Regulatory Experience

This is where Marin trips up contractors who haven’t built here before.

• Direct Marin County project experience, not just general California experience.
• Familiarity with your specific jurisdiction. A project in unincorporated Marin follows a different review path than one in San Rafael or Larkspur.
• Wildland-Urban Interface (WUI) knowledge, if your lot sits in a fire hazard zone. Marin’s rules on exterior materials are among the strictest in the state.
• Hillside and geotechnical experience, for sloped or view lots that may need soils reports and grading permits.
• Design review familiarity, for towns like Ross, Belvedere, or Mill Valley, where architectural review boards weigh in before a permit is issued.
• A real answer on creek setbacks or environmental review, if your property is near a waterway or protected habitat.

Heads up: If a contractor can’t speak specifically to your jurisdiction’s process, it’s worth asking why.

Design-Build Process & Communication

How a contractor is structured affects how smoothly your project runs.

• A true design-build model, where one team owns both design and construction, rather than passing you between a separate architect and builder.
• A single point of contact, usually a project manager, for the life of the project.
• A clear communication plan. How often will you hear from them, and in what format?
• Budget input during design, not after the plans are finished.
• A defined change order process, so you know what happens when something needs to shift.

Portfolio, References & Local Reputation

A polished website only tells you so much.

• A portfolio of custom or luxury homes similar in scope to yours.
• References you can actually call, ideally from Marin or a comparable market.
• Membership in local trade groups, such as the Marin Builders Association.
• A decade or more in the local market. Longevity matters more here than in less specialized regions.
• Recognition or awards from local or industry sources.

Contract & Budget Clarity

This is where good intentions turn into, or fail to become, a workable agreement.

• A detailed written contract before any work begins.
• A payment schedule tied to milestones, not a lump sum upfront.
• A clear system for tracking budget and change orders.
• A realistic timeline with milestones, not just a start and end date.
• A clear line between what’s included and what’s an upgrade or allowance item.

Red Flags to Watch For

A few signs it’s worth pausing before you sign:

• Reluctance to share a license number or proof of insurance
• Pressure to sign quickly or pay a large deposit upfront
• No Marin-specific project references
• Vague or dismissive answers about WUI compliance or local permitting
• A bid noticeably lower than every other quote you’ve received, with no clear explanation why

Frequently Asked Questions

How long should I spend interviewing general contractors before hiring one?

Most homeowners talk to at least two or three contractors before deciding. For a project the size of a custom home, give yourself several weeks to check references, compare bids, and confirm licensing rather than deciding after a single meeting.

What license should a Marin County general contractor hold?

Look for an active California contractor’s license through the CSLB, in a classification that matches your project (typically a B general building license for custom homes). Confirm it directly on the CSLB website rather than taking a business card’s word for it.

Why does WUI compliance matter so much for hillside or fire-zone properties?

Marin has some of the strictest wildfire construction rules in California, including restrictions on combustible exterior materials in high fire hazard zones. A contractor unfamiliar with these rules can end up redesigning your exterior mid-project, which costs time and money.

Is a design-build contractor different from a general contractor?

A general contractor may only handle construction, working from plans an architect already finished. A design-build contractor owns both design and construction under one team, which usually means fewer coordination gaps and clearer accountability.

What’s a reasonable deposit before work starts?

Deposits vary by project size and contract terms. A payment schedule tied to completed milestones is a healthier structure than a large lump sum upfront. Ask any contractor to explain their schedule in plain terms before you sign.

What if my property is in unincorporated Marin instead of a specific town?

Unincorporated Marin is reviewed directly by the county, while incorporated towns like San Rafael or Mill Valley run their own planning departments. The requirements aren’t identical, so it’s worth asking a contractor how they’ve handled projects in your specific jurisdiction.

How do I check if a contractor is in good standing?

Search their license number on the CSLB website. It shows license status, bond information, insurance status, and any complaints or disciplinary actions on file.
