Berkeley's Short-Term Rentals: The Rules That Matter

Every city handles short-term rentals a little differently. In Berkeley, California, there are 11 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Extended Home Share

Berkeley permits unlimited extended home-share nights when the host stays onsite and rents only a portion of the dwelling, recognizing roommate-style arrangements as distinct from whole-home rentals.

Key details: Night cap: None when hosted. Tax: TOT collection required. Recordkeeping: Guest log one year. Code: BMC 23.328.

Failing to register an extended home-share, omit transient tax, or maintain guest logs leads to fines starting at 250 dollars and rising to 1,000 dollars per repeat violation.

Taxes & Fees

Beyond the citywide 12% occupancy tax, Berkeley's short-term rental ordinance layers on a host enforcement fee of 2% of rents charged and requires $1 million in liability insurance, a Zoning Certificate and a business license before a host residence can be listed.

Key details: Enforcement fee: 2% of rents charged. Occupancy tax: 12% under BMC Ch. 7.36. Liability insurance minimum: $1,000,000. Unhosted stay cap: 90 days per calendar year. Required approvals: Zoning Certificate and Business License.

A host who skips the Zoning Certificate, business license, enforcement fee or $1 million insurance requirement is subject to the general penalty and administrative citation provisions of BMC Sections 1.20 and 1.28, and operating in violation is also declared a public nuisance abatable under Sections 1.24, 1.26 and 23.414. A host is barred from operating any short-term rental for one year after a third violation affidavit is issued under the Second-Response Ordinance for loud or unruly gatherings.

Compared to other cities, Berkeley takes a harder line on taxes & fees. The enforcement and penalty structure reflects that.

Repeat Violator Strikes

A Berkeley short-term rental host loses the right to operate for a full year after a third violation affidavit is issued under the city's Second Response Ordinance. The rule ties directly to noise and party enforcement under BMC Chapter 13.48.

Key details: Strike threshold: Third violation affidavit. Penalty: One-year operating ban. Underlying ordinance: Second Response Ordinance, BMC Ch. 13.48. General penalties: BMC §§ 1.20, 1.28. Resident lawsuit notice: 30 days written notice required.

A third violation affidavit under the Second Response Ordinance triggers an automatic one-year operating ban under Section 23.314.060.A, on top of general penalties under Sections 1.20 and 1.28 and nuisance abatement under Sections 1.24, 1.26, and 23.414. The prevailing party in an enforcement action may recover attorneys' fees, capped at the City's own reasonable fees, and any Berkeley resident may sue for injunctive relief after 30 days' notice to the City and host.

This is not one of those rules that cities tend to ignore. Berkeley actively enforces its repeat violator strikes requirements.

Host Platform Liability

Berkeley lets a hosting platform like Airbnb stand in for the host on money obligations: it can pay the host's enforcement fee and it must, along with the host, cover the transient occupancy tax. Sections 23.314.050(E) and (H) set the split.

Key details: Platform definition: BMC § 23.314.020(A)(4). Enforcement fee: 2% of rents, platform may pay. Occupancy tax duty: Host or platform, either may pay. Fee revision: By City Council resolution.

Nonpayment of the enforcement fee or transient occupancy tax, whether by the host or by a hosting platform paying on the host's behalf, is a violation of Chapter 23.314 punishable under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations), and the host's Zoning Certificate remains at risk of revocation-track enforcement regardless of which party was supposed to remit.

Night Caps

When the host is not on site, Berkeley caps a short-term rental at 90 days per calendar year. Section 23.314.050(B)(2) sets that limit, and going over it is a Chapter 23.314 violation enforceable through the City's general penalty and administrative citation process.

Key details: Unhosted cap: 90 days per calendar year. Hosted rentals: No day limit, § 23.314.050(B)(1). Tracking basis: Presence filings, § 23.314.050(A). Penalty for excess days: BMC §§ 1.20, 1.28, 1.24/1.26.

Section 23.314.060(B)(1) makes any violation of Chapter 23.314, including exceeding the 90-day unhosted cap, punishable under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations); subsection (B)(2) additionally treats the violation as a public nuisance subject to abatement under Sections 1.24, 1.26 and 23.414, with attorneys' fees available to a prevailing party if the City elected up front to seek them.

Host Presence Rule

Berkeley defines 'host present' as the host actually living in the host residence during the rental period, and that status controls how many nights the unit can be rented. Section 23.314.050(B)(1) gives hosted rentals unlimited days a year once the host meets that presence test.

Key details: Definition section: BMC § 23.314.020(A)(3). Hosted rental limit: Unlimited days per year. Multi-unit parcels: Presence counts on any unit on parcel. Proof required: Filed with Planning and Development Dept..

Falsely claiming host presence to obtain the unlimited-day allowance is a documentation violation under Section 23.314.050(A) and is enforced the same way as any other Chapter 23.314 violation, through BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations), plus nuisance abatement under Sections 1.24, 1.26 and 23.414 if the false claim enabled a nuisance-generating rental.

Short-Term Rental Permits

Berkeley will not let anyone rent a home for fewer than 14 days without a Zoning Certificate and a city Business License first. Table 23.202-1 lists short-term rentals as a ZC* use in residential districts, and Chapter 23.314 spells out the paperwork the Planning and Development Department requires before a host can operate.

Key details: Permits required: Zoning Certificate and Business License. Zoning status: ZC* use, Table 23.202-1. Issuing department: Planning and Development. Ad requirement: Zoning Certificate number on every listing. Penalty code: BMC §§ 1.20, 1.28, 1.24/1.26.

Operating or advertising a short-term rental before the Zoning Certificate and Business License are approved is enforced under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations), and the City can pursue it as a public nuisance subject to abatement under Sections 1.24, 1.26 and 23.414. A prevailing party can recover attorneys' fees if the City elected up front to seek its own, and any Berkeley resident can sue for injunctive relief after giving the City and the host 30 days' written notice of the alleged nuisance.

Insurance Requirements

Every short-term rental in Berkeley has to carry at least $1 million in liability insurance. Section 23.314.050(F) lets either the host or the hosting platform hold that coverage, so a host booking exclusively through a platform that provides host-liability coverage can rely on it to meet the rule.

Key details: Minimum coverage: $1,000,000 liability insurance. Who can hold it: Host or hosting platform. Governing section: BMC § 23.314.050(F). Linked disclosure duty: § 23.314.050(G) noise/smoking notices.

Operating a short-term rental without the $1 million liability coverage required by Section 23.314.050(F) is a violation of Chapter 23.314's operating standards, enforceable under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations) and subject to public-nuisance abatement under Sections 1.24, 1.26 and 23.414 if the uninsured operation is also generating neighborhood complaints.

Primary-Residence-Only Rule

Berkeley bans short-term rentals everywhere except the host's own principal residence. Section 23.314.040(A) states it flatly, and Section 23.314.020(A)(5) defines that residence by where the host actually lives, sleeps, and returns, not by ownership alone.

Key details: Core rule: STRs allowed only in host residence. Residence test: Principal residence, indicia-based. Proof examples: DMV registration, driver's license, voter reg.. Related bars: No BMR units; 5-yr bar after no-fault eviction.

Operating a short-term rental in a unit that is not the host's documented principal residence is enforced under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations) and can be treated as a public nuisance subject to abatement under Sections 1.24, 1.26 and 23.414, with any Berkeley resident able to seek injunctive relief after 30 days' notice to the City and host under Section 23.314.060(B).

This is not one of those rules that cities tend to ignore. Berkeley actively enforces its primary-residence-only rule requirements.

Noise Rules

A Berkeley short-term rental host has to comply with the city's Second Response Ordinance, and a third violation affidavit for loud or unruly parties bans that host from operating any short-term rental for a full year. Section 23.314.060(A) sets the rule; excessive noise itself is also defined as a public nuisance.

Key details: Noise compliance duty: BMC § 13.48 Second Response Ordinance. Third-strike penalty: 1-year operating ban. Nuisance examples: Excessive noise, crowds, minors drinking, fights. Guest disclosure: Chapter 13.40 Noise Ordinance copy required.

A third violation affidavit under the Second Response Ordinance triggers a one-year ban on operating any short-term rental under Section 23.314.060(A); noise and party nuisances at a short-term rental are separately punishable under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations) and abatable as a public nuisance under Sections 1.24, 1.26 and 23.414, and any Berkeley resident can bring a private injunctive action after giving the City and host 30 days' written notice.

This is one of the stricter rules in Berkeley's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Occupancy Limits

Berkeley does not put a flat headcount on a short-term rental; Section 23.314.050(C) sends the occupant limit to the Housing Code, whose floor-area math in Section 19.40.030 requires at least 120 square feet in one room and adds 50 square feet for every sleeping-room occupant past two.

Key details: Occupant limit source: BMC ch. 19.40, incorporated by § 23.314.050(C). Minimum single room: 120 sq. ft.. Other habitable rooms: 70 sq. ft. minimum. Extra sleeping-room occupant: +50 sq. ft. each past two. Ceiling height minimum: 7 ft. 6 in. (7 ft. in 1-2 family homes).

Renting a short-term rental unit to more transients than its rooms support under the Section 19.40.030 floor-area formula, as incorporated by Section 23.314.050(C), is enforced under BMC Sections 1.20 (General Penalty) and 1.28 (Administrative Citations), and an overcrowded unit generating neighbor complaints can also be pursued as a public nuisance subject to abatement under Sections 1.24, 1.26 and 23.414.

The Bottom Line

Berkeley is tougher than many cities when it comes to short-term rentals. Out of the 11 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Berkeley, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Berkeley's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
