Move a Marin County Project From Property Check to Electronic Plans, Released Holds and Final Approval
The most important first step is deciding whether Marin County is actually your permit authority. County Building and Safety mainly serves unincorporated Marin. A property inside San Rafael, Novato, Mill Valley, Sausalito or another incorporated city or town normally uses that local building department instead.
After jurisdiction is confirmed, the project follows one of two very different paths: a quick online maintenance or minor-improvement permit, or a plan-reviewed permit using electronic applications and ProjectDox. Larger projects can also trigger Planning, coastal, wildfire, septic, Fire, Public Works, water, sanitation, green-building and accessibility requirements.
This guide explains both beginner and professional workflows, current 2026 electronic-plan rules, published review stages, inspection holds, fees, permit expiration, record lookup, contractor checks and final closeout.
Choose the Marin County Permit Task You Need
Use the Fast Residential Lane or the Full Multi-Agency Lane
Simple practical path
- Confirm the property is in unincorporated Marin.
- Write one clear sentence describing all proposed work.
- Check whether the project is exempt, self-service or plan-reviewed.
- Prepare ownership, contractor, value and project information.
- Complete the official online application.
- Do not start until the permit is issued.
- Release holds, complete inspections and save final proof.
Professional control points
- Map Planning, coastal, Fire, septic, Public Works, water and sanitation dependencies.
- Confirm 2025 California code, Marin amendments, green-building and WUI requirements.
- Coordinate architecture, structure, MEP, civil, energy and agency documents.
- Control ProjectDox sheet naming, versions, corrections and design changes.
- Separate application deposits, issuance fees, impact fees and agency charges.
- Clear foundation and close-in holds before requesting inspections.
- Close the permit, all related agency conditions and owner documentation together.

Application and issuance split
The county explains that the Building & Safety service fee is generally divided approximately 77% to the application/plan-review stage and 23% to issuance and inspections.
County surcharges
The fee explanation lists a Planning surcharge of 10% and a technology-enhancement fee of 6%, each calculated from the building application and issuance fees.
Roads impact fee
Public Works lists a roads-impact charge of 1% of the improvement value for qualifying improvements valued at least $10,000.
State taxes
Seismic-monitoring and California green-building taxes are calculated from the project value, subject to minimum charges.
Construction and demolition
The county’s fee explanation lists a construction-and-demolition waste charge generally ranging from $50 to $250 depending on project size.
Other reviewing agencies
Planning, Fire, Environmental Health, Public Works, water, sanitation and school districts can charge separate review, inspection, connection or impact fees.
Check Marin County ADU and Accessibility Fee Programs
ADU fee waiver through December 31, 2026
Marin County extended its ADU and JADU permit-fee waiver program through December 31, 2026 for qualifying projects in unincorporated Marin.
The waiver can apply to qualifying County Community Development Agency fees, including Building & Safety and Planning charges. Eligibility, deed restrictions or affordability requirements can vary by program category.
Accessibility-only permit fee waiver
The county has publicized a building-permit fee waiver when the sole scope of the permit improves accessibility to an existing structure.
Confirm whether the proposed work qualifies before combining it with unrelated remodel work in one permit.
Wildfire, Coastal, Septic and Public Works Reviews Can Control the Project
Wildland-Urban Interface
Properties near wildland can require ignition-resistant materials, defensible-space coordination, fire access, water supply and district-specific construction standards.
Coastal Zone
Development in Stinson Beach, Bolinas, Point Reyes, Dillon Beach, Muir Beach, Tomales, Olema and other coastal areas can require a Coastal Permit, exclusion or categorical-exclusion review.
Septic system
Remodels, additions, pools, decks, bedrooms and new structures can affect wastewater capacity and required setbacks from the tank and dispersal field.
Public Works
Driveways, grading, drainage, utilities, retaining work and construction affecting a county road or right-of-way can require Land Development or encroachment review.
Project condition |
Questions to answer early |
Why delay is expensive |
|---|---|---|
WUI or high fire-hazard area |
Which fire authority serves the parcel? What roof, siding, vent, glazing, deck and vegetation rules apply? |
Material substitutions and access improvements can redesign the project. |
Coastal location |
Is a Coastal Permit, exclusion or categorical exclusion required? Is the decision appealable? |
Building plans may depend on Planning approval and appeal periods. |
Existing septic system |
Will bedroom count, wastewater flow, footprint or setback change? Is a zero-impact certification allowed? |
Septic limitations can control building area, location and occupancy. |
Steep slope or drainage work |
Are geotechnical, grading, drainage, retaining or erosion-control plans required? |
Site engineering can materially change foundation and project cost. |
County road or right-of-way |
Does the driveway, utility, trench, staging or structure affect a county-maintained road? |
Encroachment approval may be needed before or during building work. |
Private water or district services |
Which water and sanitation district serves the property, and what capacity or connection fees apply? |
District holds can block foundation, close-in or final inspections. |
Special Self-Service Options for Properties With Septic Systems
Maintenance and minor improvements
Eligible projects such as solar, battery storage, backup generators and nonstructural kitchen/bathroom remodels can use the self-service route.
A Voluntary Septic System Zero Impact Certification can be available for qualifying work.
Repairing an existing permitted structure
Replacement or repair of an existing permitted deck, pool, spa, foundation or retaining wall still uses the plans-and-review application.
Eligible applicants may be able to submit the county self-certification form instead of full Environmental Health review.
Current California and Marin Green-Building Rules
2025 California code cycle
Marin County adopted the 2025 California Building Standards Code with local amendments effective January 1, 2026.
Green-building requirements
Updated Marin green-building rules took effect January 1, 2026 and apply differently to new construction, additions, renovations, multifamily and nonresidential projects.
Large residential renovations
One- and two-family additions or alterations of 500 square feet or more can trigger the county’s 2026 green-building compliance process and energy-savings point system.
A Planning Permit May Be Required Before the Building Permit
Planning route |
Typical reason |
Building-permit impact |
|---|---|---|
Design Review |
New construction, additions, visible exterior changes or community design standards |
Approved design and conditions must match building plans. |
Coastal Permit |
Development within the Marin coastal zone |
Approval or valid exclusion may be required before building issuance. |
Site Plan Review |
Development needing site-layout and ordinance compliance review |
Building plans must reflect approved site placement and conditions. |
Variance |
Requested deviation from dimensional development standards |
Building permit cannot assume unapproved setback, height or coverage relief. |
Tree Removal Permit |
Removal or impact to regulated trees |
Construction and grading plans must protect or replace trees as conditioned. |
Use Permit or new use |
Business, commercial, institutional or other land-use authorization |
Tenant-improvement and occupancy plans must match the permitted use. |
ADU or JADU review |
New unit, conversion or legalization |
Building, septic, Fire, energy and housing-program conditions can apply. |

Marin County Building Permit, Inspection and Records FAQs
Where do I apply for a Marin County building permit?
Use the official Marin County Online Permitting site. The same starting page provides a self-service route for eligible maintenance and minor-improvement permits and a plans-and-review route for larger projects.
Does Marin County Building & Safety cover every city in the county?
No. Marin County Building & Safety mainly serves unincorporated Marin. Incorporated cities and towns such as San Rafael, Novato, Mill Valley, Sausalito, Larkspur, Corte Madera, San Anselmo, Fairfax, Belvedere, Tiburon and Ross generally operate their own permitting systems.
Does Marin County accept paper building plans in 2026?
No. Effective January 1, 2026, plan submittals must be electronic. Applicants complete the Submittal Checklist and Part A online and receive a ProjectDox invitation for plan uploads.
Which Marin County permits can be obtained without submitting plans up front?
Eligible residential maintenance permits include certain electrical, plumbing, gas, mechanical, reroof, siding, stucco and same-size nonstructural window/door work. Minor-improvement permits include rooftop solar, energy storage, backup generators and qualifying nonstructural kitchen/bathroom remodels.
How long does Marin County plan review take?
The county publishes a snapshot of about three days for intake, 15 days for prescreen, two to four weeks for initial plan review, three to five days for pre-issuance and about three days for final payment and issuance. Corrections and other-agency review can extend the overall six-to-eight-week planning expectation.
How do I schedule a Marin County building inspection?
Release all applicable holds first. Then call the 24-hour automated line at 415-473-6560, text 877-410-7201 or use online scheduling for eligible permits beginning with B. Have the permit number, address and three-digit inspection code ready.
When will the Marin County inspector arrive?
The inspector normally calls or texts between 8:00 and 9:00 AM on inspection day and provides a two-hour arrival window. You may also call Building & Safety at 415-473-6550 after 8:00 AM for the expected window.
What is a Marin County inspection hold?
A hold is a required action that blocks a specific inspection. Foundation and close-in holds are common. Holds may come from Building & Safety, Planning, Fire, Public Works, Environmental Health, school, water or sanitation districts.
How long is a Marin County building permit valid?
Marin County states that a building permit expires after one year. A passed inspection counts as verified progress and extends the expiration by another year.
How do I check a Marin County permit before buying a property?
Use the official permit lookup to search by address, area, map or permit number. Review the inspection and final status rather than relying only on the existence of a permit. Contact Building & Safety when older history is missing.
