Oakland Contractor BondsRetrofit Demand Meets a Two-Layer Bonding Reality
Oakland Municipal Code Chapter 15.27 requires seismic evaluation and retrofit of every qualifying wood-frame soft-story building in the city — a program the City itself estimated at somewhere between 1,400 and 2,600 buildings holding over 24,000 residential units. That mandate is driving sustained demand for Class B general building and Class C-5 framing contractors, and every one of them needs the same $25,000 statewide CSLB bond under Business and Professions Code §7071.6 before they can pull a permit — plus, on many jobs, a separate city-filed excavation or encroachment layer OakDOT and Public Works administer independently.
Oakland Municipal Code Chapter 15.27: The Retrofit Program Behind the Bond Demand
Ordinance No. 13516 C.M.S. added Chapter 15.27, and it is still generating permitted work city-wide
Oakland City Council adopted Ordinance No. 13516 C.M.S., adding Oakland Municipal Code Chapter 15.27 — "Mandatory Seismic Evaluation and Retrofit of Certain Multi-Unit Residential Buildings" — following the 2009 mandatory screening program under OMC Chapter 15.26. The findings behind the ordinance are specific: a joint City/Association of Bay Area Governments (ABAG) survey identified roughly 1,400 to 2,600 potential soft-story buildings holding more than 24,000 residential units, representing at least 11% of Oakland's rental housing stock — and, per the City's own estimate, as much as two-thirds of the city's expected housing losses in a future damaging Hayward Fault earthquake.
Subject Buildings (OMC §15.27.030): constructed or permitted before January 1, 1991 (or designed to the 1985-or-earlier Uniform Building Code), with five or more dwelling units and a wood-frame "target story." If none of those three conditions apply, the building isn't covered. Buildings that complete a compliant retrofit get a 15-year conformance period (§15.27.040) before the City can require another seismic upgrade of the same force-resisting system.
OMC Chapter 15.27 Compliance Tiers — Table 15.27.070
Deadlines run in years after 30 days following the chapter's effective date
Tier 1
4-year retrofit deadline
- 20+ dwelling units (not Tier 2/3-eligible) — subcategory Tier 1-LB
- OR missed the 2009 screening deadline (OMC §15.26.230), roughly 7/28/2011 — subcategory Tier 1-NR
- Mandatory evaluation + initial affidavit: 2 yrs · Retrofit permit: 3 yrs · Retrofit complete: 4 yrs
Tier 2
5-year retrofit deadline
- 5–19 dwelling units, not Tier 3-eligible
- OR legally permitted business/mercantile occupancy on the target story
- Mandatory evaluation + initial affidavit: 3 yrs · Retrofit permit: 4 yrs · Retrofit complete: 5 yrs
Tier 3
6-year retrofit deadline
- Legally permitted residential occupancy on the target story, not Tier 1/2
- The most common assignment for typical apartment buildings
- Mandatory evaluation + initial affidavit: 4 yrs · Retrofit permit: 5 yrs · Retrofit complete: 6 yrs

Zoning and rent-pass-through relief travel with the mandate
The same ordinance amended the Oakland Planning Code to add §17.102.250, granting special zoning exceptions to buildings undergoing permitted Chapter 15.27 retrofit work, and directed the Rent Adjustment Program (OMC Chapter 8.22) to set an amortization schedule so owners can pass retrofit costs through to tenants as a capital improvement. Neither of these change your CSLB bonding requirement — they change how the owner finances and permits the job you're bidding.
Who signs off before a contractor ever touches the frame
OMC §15.27.060 requires evaluation reports and schematic retrofit reports to be sealed by a licensed architect or civil engineer before a retrofit permit is issued — that engineering step happens upstream of the contractor. Once the design is stamped, the CSLB-bonded Class B or C-5 contractor executes the permitted retrofit work and requests final Bureau of Building inspection under §15.27.050(D).
OakDOT's Two Separate Right-of-Way Instruments — a Bond and an Insurance Policy
Excavation gets a cash-backed performance deposit; encroachments get a liability policy. They are not interchangeable.
Excavation Permit — OMC §12.12.022 Performance Deposit
Before excavating in the Oakland right-of-way — soil boring, monitoring-well work, potholing, trenching, UST/UGS tank removal — the Transportation Department (OakDOT) requires a bond, cash deposit, or other Public-Works-acceptable security under Chapter 12.12 (Excavation).
Obstruction / Encroachment Permit — OMC Chapter 12.08
Blocking or obstructing the sidewalk, bike lane, or a travel lane — scaffolding, a dumpster, a fenced staging area for retrofit work — needs an Obstruction Permit under Chapter 12.08 (Encroachments), plus an approved Traffic Control Plan when a lane is affected.
Official California (Oakland) Requirements
"Each applicant shall submit and maintain with Public Works a bond, cash deposit, or other security acceptable to Public Works securing the faithful performance of the obligations of the owner and its agent under any permit to excavate and comply with all terms and conditions of this chapter. The bond or deposit shall be in the sum of $25,000.00 or as determined by the Director of Public Works, his or her designee. Each deposit or bond shall be retained by the City for a period of three years after the satisfactory completion of the excavation."Oakland Municipal Code §12.12.022 (Performance Deposit), Chapter 12.12 Excavation • Oakland Municipal Code §12.12.022 (Ord. No. 13300, §1, 3-31-15)
Neither city-layer instrument is filed with CSLB, and neither substitutes for the statewide $25,000 CSLB bond covered below. Confirm which permit applies to your scope at the OakDOT Permit Counter, 250 Frank H. Ogawa Plaza, 2nd Floor, before pricing the job.

Same instrument, same amount, everywhere in California — Oakland doesn't change it
Every Oakland contractor — whether bidding a soft-story retrofit under Chapter 15.27, a routine kitchen remodel, or a sidewalk repair that never touches the right-of-way — must hold the same $25,000 CSLB license bond under BPC §7071.6 before the Contractors State License Board will issue, renew, or reactivate a license. LLC contractors carry an additional $100,000 employee/worker bond under BPC §7071.6.5 — $125,000 total — regardless of whether their Oakland work involves the soft-story program at all. For the full statewide breakdown of classifications, LLC bonding, and the 2023 SB 607 increase from $15,000, see our California contractor license bond page — this Oakland guide focuses on what the city layers on top.

Alameda County Notes: Recorded Titles, Unincorporated Roads, and Berkeley's Different Rulebook
Three things change the moment you step outside Oakland's city line — or don't leave, but still touch the County Recorder
Chapter 15.27 compliance can reach the County Recorder without you ever leaving Oakland
OMC §15.27.120(C)(2) lets Oakland's Bureau of Building file a statement describing a Chapter 15.27 violation with the Alameda County Recorder's office, released only once the owner corrects it. Separately, §15.27.140 requires the Bureau to report each subject building's compliance status and parcel number to the Alameda County Clerk-Recorder every six months. Retrofit contractors bidding on a building with a checkered compliance history should factor in that the paper trail isn't only at 250 Frank H. Ogawa Plaza — it can also sit in the county's own property records.
Unincorporated Alameda County runs its own right-of-way permitting
Contractors who cross Oakland's border into unincorporated pockets of the county — areas like San Lorenzo, Ashland, Cherryland, or Castro Valley — leave OakDOT's jurisdiction entirely. The Alameda County Public Works Agency issues its own encroachment permits for county road right-of-way, with bonding tied to the road commissioner or engineer's estimate for the specific job rather than Oakland's flat $25,000 excavation figure. If a job spans both Oakland streets and county-maintained roads, confirm which agency has jurisdiction over each segment before you assume one bond covers the whole scope — contact ACPWA directly to confirm current bonding amounts for county-road work.
Berkeley's SWOF program is a different ordinance with a different cutoff
Berkeley, also in Alameda County, runs its own mandatory soft-story program under Berkeley Municipal Code Chapter 19.39 — covering soft, weak, or open-front (SWOF) wood-frame buildings with five or more units permitted before January 1, 1978, versus Oakland's January 1, 1991 cutoff. A C-5 or Class B contractor working both cities cannot assume Oakland's Chapter 15.27 rules travel to a Berkeley job — the subject-building test, deadlines, and program administration are entirely separate, even though the underlying $25,000 CSLB bond is identical in both cities.
| City | Ordinance / Code | Construction Cutoff | Minimum Units |
|---|---|---|---|
| Oakland | OMC Ch. 15.27 (Ord. 13516 C.M.S.) | Before 1/1/1991 | 5+ dwelling units |
| Berkeley | BMC Ch. 19.39 | Before 1/1/1978 | 5+ dwelling units |
CSLB Bond Premium by Credit Tier — Plus What the City Layers Cost Separately
The $25,000 bond is priced on credit; the excavation deposit isn't a premium at all
Annual Premium on a $25,000 CSLB Bond
Based on a $25,000 bond amount
- Excellent (750+)Rate: 0.5%–1%$125–$250
- Good (680–749)Rate: 1%–2%$250–$500
- Fair (620–679)Rate: 2%–4%$500–$1,000
- Below 620Rate: 4%–10%+$1,000–$2,500+
LLC contractors add the $100,000 BPC §7071.6.5 bond on top — priced separately, on the same credit tiers.
The OMC §12.12.022 excavation deposit isn't underwritten the same way — Public Works accepts a surety bond, but many contractors instead post a cash deposit or letter of credit for the $25,000 figure, since it's refundable (minus any restoration deduction) after the three-year retention period rather than a sunk annual premium. If you'd rather not tie up $25,000 in cash for three years per job, ask about a dedicated excavation surety bond instead of a cash deposit — the annual premium is typically a small fraction of the deposit amount.
