Commercial Real Estate in Jenner: Coastal Permits, Commercial Tourist Zoning and Rural Community Limits

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Jenner sits where the Russian River meets the Pacific on Highway 1, a small cluster of homes, an inn with cottages, a restaurant or two, a visitor center and boating businesses on the estuary, with steep coastal hills above. Every parcel is in the Coastal Zone and unincorporated, so the County’s Local Coastal Plan and coastal zoning code govern, and most development needs a coastal development permit. Confirm each parcel’s zoning with Permit Sonoma before relying on this page.

Who controls the parcel

Coastal plan. The Board adopted a comprehensive Local Coastal Plan update on July 17, 2023. The California Coastal Commission conditionally certified it on November 14, 2024, and the Board accepted the certified version on February 4, 2025, so the new LCP is now in effect.
Implementation. The County says it will carry out the plan by amending its Coastal Zoning Ordinance and Coastal Administration Manual. Expect the code text to change.
Coastal zoning. Chapter 26C of the County Code applies inside the Coastal Zone, with its own districts, design review and coastal permit rules. The Official Zoning Database shows each parcel’s zoning.
No urban service area. Jenner does not appear among the 21 areas on the County’s urban service area layer.
Water. Permit Sonoma’s referral list names Russian River Utility as serving Jenner and also lists Jenner under County Transportation and Public Works.

What the Local Coastal Plan says about Jenner

The Board-adopted 2023 Land Use Element makes Jenner one of the coast’s Rural Communities (Policy C-LU-6j). Its key points:

Commercial scale. Objective C-LU-6.3 allows only limited new commercial activity in Jenner, sized to its scale and character.
Infill conditions. Policy C-LU-5m permits modest visitor-serving and local-serving infill only where water supply and wastewater treatment and disposal requirements can be met.
Density. Outside the Bodega Bay urban service area, residential densities are one unit per acre or less (Policy C-LU-6a).
Existing lodging. The plan’s visitor facilities table lists the 21-room Jenner Inn & Cottages and the Jenner Visitors’ Center.
Visitor priority. The plan quotes Coastal Act Section 30222: land suited to visitor-serving recreation has priority over private residential and general commercial development, though not over agriculture or coastal-dependent industry.

The Coastal Commission certified the plan with modifications, so confirm the certified wording of these policies.

Lodging, height and site standards in CT

The CT text in Chapter 26C sets the working numbers:

Hotels of 16 or more units. These need a use permit. Room caps are 200 in urban service areas, 100 in rural areas with public sewer and 50 otherwise. With Jenner outside any urban service area, one of the lower caps would apply.
Height. West of Highway 1, the limit is 16 feet for residential and 24 feet for commercial buildings. East of the highway it is 24 feet where visible from a designated scenic road and 35 feet where not. Increases need findings on views and community character.
Lot size. Minimums run from 10,000 square feet with public water or sewer, to one acre with water only, to 1.5 acres with neither.
Slopes and access. No development on slopes over 30% unless no feasible alternative exists. Coastal access easements may be required.
Design review. Required for all permitted uses, and new utility lines go underground.

Vacation rentals and coastal permits

Permit Sonoma allows vacation rentals in the Coastal Zone with a zoning permit, a certified property manager, a TOT number and a license, under countywide performance standards. The LCP Land Use Element counted about 600 coastal vacation rentals in summer 2022, mostly at The Sea Ranch and Bodega Harbour. It treats them as among the lowest-intensity visitor uses. Its Policy C-LU-4g bars use of ADUs and JADUs as vacation rentals or other uses subject to TOT. Under Chapter 26C, Article XXXIV governs coastal development permits; some County coastal decisions can be appealed to the Coastal Commission. See our vacation rental rules.

Flood and shoreline

Jenner’s estuary and shoreline parcels may be mapped in FEMA flood zones, including coastal high hazard (VE) areas. County Chapter 7B allows no enclosure below the lowest floor in VE zones except breakaway walls, bars new manufactured homes there, and requires nonresidential buildings to be elevated or floodproofed 12 inches above base flood elevation. See our Jenner coastal property records and coastal home inspections pages.

Transfer tax, business tax and property tax

The County Recorder charges $0.55 per $500, less assumed loans, and Jenner has no city tax. Lodging operators collect County TOT; we did not verify its rate. A change of ownership generally triggers Proposition 13 reassessment.

Due diligence that matters in Jenner

Use our commercial due diligence checklist, and add:

Pull the coastal zoning and every past coastal development permit and its conditions.
Confirm water service and septic capacity in writing; LCP infill depends on both.
Check slope, bluff, geologic hazard and VE flood mapping.
Measure existing building heights against the CT limits on your side of Highway 1.
For lodging, confirm the room count the permits actually authorize.
Track the County’s coastal zoning amendments implementing the 2025 LCP.
