AB 1621 Passes Assembly 67-0: Two-Resubmittal Cap Ends Permit Delays for Pacific Beach Builders

Introduction: The Endless Resubmittal Cycle Ends

California contractors face a frustrating reality: submit building plans, wait 30-60 days for review, receive vague correction requests, resubmit, wait another 30-60 days, and repeat indefinitely. Each resubmittal cycle adds thousands in carrying costs—construction loan interest, property taxes, insurance—while contractors struggle to keep crews scheduled and homeowners watch budgets spiral.

Assembly Bill 1621 aims to end this cycle. On April 27, 2026, the California Assembly passed AB 1621 with a unanimous 67-0 vote, prohibiting local agencies from requesting more than two plan check resubmittals for housing permits unless documented health or safety risks exist. The bill also reduces appeal determination timelines from 60 to 30 business days for projects under 26 units, and from 90 to 45 days for larger developments.

For Pacific Beach, La Jolla, and Mission Beach contractors navigating San Diego Development Services permit reviews—especially for ADUs, major remodels, and coastal construction projects—AB 1621 represents a fundamental shift from endless bureaucratic cycles to predictable, enforceable timelines. After receiving Senate Appropriations Committee approval on August 13, 2026, the bill is advancing toward final passage and potential implementation in 2027.

This legislative analysis examines AB 1621's provisions, its impact on San Diego coastal builders, and practical steps contractors can take to prepare for implementation.

What AB 1621 Changes: The Two-Resubmittal Cap Explained

AB 1621 introduces a strict limit on how many times local building departments can request plan revisions during the permit review process. Under current law, agencies can effectively demand unlimited resubmittals, restarting the review clock with each request and creating indefinite delays.

The bill prohibits local agencies or state agencies from requiring or requesting more than two plan check and specification reviews in connection with an application for a building permit. This two-resubmittal maximum applies to all housing development projects, from single-family homes and ADUs to multi-unit residential buildings.

However, the cap includes a critical exception: agencies can require additional reviews beyond the two-resubmittal limit if they provide written findings based on substantial evidence in the record that the additional review is necessary to address a specific, adverse impact on public health or safety. This health-and-safety exception prevents the cap from compromising legitimate building code enforcement while eliminating arbitrary delay tactics.

For Pacific Beach contractors dealing with complex coastal permits, seismic requirements, or bluff setback regulations, the two-resubmittal cap means agencies must consolidate all feedback into the first two review cycles rather than issuing piecemeal correction requests that drag projects through five, six, or more rounds of resubmittal.

The California Building Industry Association sponsored AB 1621 specifically to address this widespread problem. According to the legislation's findings, some local governments use loopholes in the law to continue delaying permits, slowing down housing production and driving up costs for California families.

Appeal Timeline Reductions: 60 to 30 Days for Small Projects

Beyond the resubmittal cap, AB 1621 significantly tightens appeal timelines when permit denials are challenged. Current law allows local agencies 60 business days to issue written determinations on appeals for projects with fewer than 26 units, and 90 business days for projects with 26 or more units.

AB 1621 reduces these timelines to 30 business days for projects under 26 units and 45 business days for projects with 26 or more units. For Pacific Beach homeowners appealing ADU permit denials or contractors challenging correction requests on single-family remodels, this represents a 50% reduction in appeal resolution time.

The practical impact is substantial. A typical Pacific Beach ADU project delayed by permit appeals currently faces an additional two to three months beyond the initial review period. Under AB 1621's streamlined timeline, that delay drops to approximately one month, reducing carrying costs and construction loan interest.

According to data from Pacific Beach Builder's 2026 permit analysis, a typical four-week permit delay on a $200,000 ADU project creates approximately $2,400-$4,800 in direct carrying costs. Each month of delay costs $4,000 in loan interest alone, not counting property taxes ($1,000-$1,500 monthly for coastal properties) and insurance ($500-$800 monthly).

The appeal timeline reductions complement AB 1621's two-resubmittal cap by creating accountability at both the initial review stage and the appeal stage. Pacific Beach contractors can leverage AB 306's state-level appeal rights when local denials are challenged, preventing agencies from using either mechanism to indefinitely stall housing projects.

Closing Permit Shot Clock Loopholes: Enforceable Timelines

California's existing Permit Streamlining Act establishes 'shot clock' requirements mandating that building departments review permits within specified timeframes: 30 business days for projects with 25 units or fewer, and 60 business days for projects with 26 or more units. However, current law contains loopholes allowing agencies to restart these clocks indefinitely.

AB 1621 closes these loopholes by limiting resubmittal requests and establishing remedies when agencies violate shot clock requirements. The bill makes violations of postentitlement permit provisions actionable violations of the Housing Accountability Act, allowing applicants to seek writs of mandate for approval if appeals are denied or timelines violated.

This enforcement mechanism is critical for Pacific Beach and La Jolla contractors who face extended reviews due to Coastal Development Permit requirements, bluff stability assessments, and California Coastal Commission coordination. Under AB 1621, if San Diego Development Services exceeds the 30-day or 60-day review timeline without documenting legitimate health/safety concerns requiring additional resubmittals, applicants can pursue legal remedies.

Courts are required to award reasonable attorney's fees to housing developers who successfully sue agencies to enforce housing reform laws. This cost-shifting provision creates a strong incentive for local agencies to comply with AB 1621's timelines rather than risk expensive litigation.

According to Attorney General guidance issued in 2026, when a local agency fails to meet review timelines established under the Permit Streamlining Act, the local agency is in violation of state law and potentially subject to Housing Accountability Act enforcement. AB 1621 strengthens this enforcement framework by explicitly tying permit review violations to HAA remedies.

Legislative Status: 67-0 Assembly Vote and Senate Progress

AB 1621 was introduced on January 22, 2026, by Assembly Member Lori Wilson (D-Assembly District 11) with coauthors Assembly Members Blanca Rubio and Buffy Wicks. The bill received amendments on March 4, 2026, and passed the Assembly floor on April 27, 2026, with a remarkable 67-0 unanimous vote—zero opposition votes and 13 abstentions.

The unanimous Assembly passage signals broad bipartisan recognition that California's permit review system requires reform. Housing production advocates and building industry representatives have long documented how unlimited resubmittal cycles delay housing construction and increase development costs, ultimately reducing housing affordability.

Following Assembly passage, AB 1621 moved to the Senate where it received further amendments on June 3, 2026, and August 20, 2026. The bill was referred to the Senate Appropriations Committee suspense file on August 3, 2026—a procedural step where bills with potential fiscal impacts undergo additional review.

On August 13, 2026, the Senate Appropriations Committee pulled AB 1621 from the suspense file and issued a 'Do Pass' recommendation, advancing the bill toward full Senate floor consideration. The mid-August suspense hearing is typically where controversial or costly bills face elimination, making AB 1621's favorable recommendation a strong indicator of likely passage.

If AB 1621 passes the full Senate and receives the Governor's signature, it would likely take effect January 1, 2027, as most California housing legislation follows the standard January 1 implementation date for bills passed in the previous legislative session.

Impact on San Diego Development Services Permit Reviews

San Diego Development Services (DSD) currently processes thousands of residential permit applications annually, including significant volume from Pacific Beach, La Jolla, and Mission Beach coastal communities. Permit processing times have doubled since the pandemic—what once took two to three months now requires five to seven months or more from submission to issuance.

Most applicants receive plan check comments requiring revisions and resubmittal, and each time you resubmit, a new review cycle begins with another three-to-six-week timeline. This resubmittal cycle is the primary factor AB 1621 targets for reform.

Under current practice, San Diego DSD has 15 business days to determine application completeness and 60 days to approve or deny a post-entitlement permit for most housing projects, following state deadlines established by SB 543. However, agencies can issue correction requests that effectively restart these timelines with each resubmittal.

AB 1621 would fundamentally change this process by limiting San Diego DSD to two plan check reviews unless the agency provides written findings documenting specific health or safety risks requiring additional review. This forces consolidation of feedback into the initial review cycles rather than staggered correction requests spanning multiple months.

For Pacific Beach ADU projects—which currently face 3-5 month approval timelines in standard cases and 6+ months when complications arise—the two-resubmittal cap creates predictability. Contractors can budget for a maximum of two correction cycles rather than open-ended delays.

Coastal projects requiring Coastal Development Permits face additional complexity. AB 462, effective October 15, 2025, already streamlined coastal ADU permits to 60-day concurrent review, down from the previous 6-18 month sequential process. AB 1621 would complement this reform by preventing excessive resubmittal requests during the building permit phase that follows coastal permit approval.

Real-World Impact: How Permit Delays Affect Pacific Beach Projects

The financial impact of permit delays compounds quickly for Pacific Beach and La Jolla builders. A typical 4-week permit delay on a $200,000 Pacific Beach ADU project creates approximately $2,400-$4,800 in direct carrying costs, not including contractor scheduling conflicts or lost rental income.

Construction financing for coastal projects typically ranges from 8-10% annual interest. On a $200,000 ADU construction loan at 9% annual rate, each month of permit delay costs approximately $1,500 in interest charges. A six-month delay due to multiple resubmittal cycles costs $9,000 in interest alone.

Property taxes continue during permit delays. Pacific Beach properties assessed at $1.2-$1.8 million pay approximately $1,000-$1,500 monthly in property taxes, which accrue during extended permit reviews. Understanding San Diego's infrastructure investment priorities helps contractors anticipate how permit delays interact with municipal project timelines and resource allocation.

Insurance costs add another $500-$800 monthly for coastal construction projects. Properties near Tourmaline Surfing Park and other Pacific Beach coastal areas including La Jolla, Mission Beach, and Bird Rock face higher insurance premiums due to salt-air exposure, coastal erosion risk, and proximity to the ocean.

Case Study: Pacific Beach ADU Delayed by Multiple Resubmittals

A 2025 Pacific Beach ADU project on Lamont Street illustrates the financial impact of unlimited resubmittal cycles. The applicant submitted complete plans in March 2025, meeting all stated requirements. San Diego Development Services requested corrections in four separate plan check cycles over seven months:

• Resubmittal 1: Electrical panel location change
• Resubmittal 2: Window egress dimension clarifications
• Resubmittal 3: Fire sprinkler specification updates
• Resubmittal 4: Balcony railing height revisions

Each issue could have been identified in the initial plan check. The staggered feedback added $18,000 in carrying costs—construction loan interest, property taxes, and insurance—that AB 1621's two-resubmittal cap would have prevented by requiring consolidated initial review.

Contractor scheduling represents a hidden cost that's difficult to quantify but significantly impacts project feasibility. When permits drag through multiple resubmittal cycles over six to nine months, contractors must reschedule crews multiple times, often losing their place in the queue and facing additional delays when permits finally issue.

AB 1621's two-resubmittal cap directly addresses these cascading costs by creating predictable timelines. Even if a project requires the maximum two resubmittals, contractors can plan for defined review cycles rather than open-ended delays.

Health and Safety Exception: When Additional Reviews Are Allowed

AB 1621's two-resubmittal cap includes a critical exception preventing the limit from compromising legitimate building code enforcement. Agencies can require additional plan check reviews beyond the two-resubmittal maximum if they provide written findings based on substantial evidence in the record that the additional review is necessary to address a specific, adverse impact on public health or safety.

This exception ensures that complex projects involving structural concerns, seismic safety, fire protection, or other legitimate public health and safety issues receive appropriate review depth. For Pacific Beach coastal construction projects dealing with bluff stability, tsunami evacuation routes, or seawall interactions, agencies retain authority to require additional reviews when documented safety concerns exist.

The key requirement is documentation: written findings based on substantial evidence. Agencies cannot simply assert generic safety concerns to bypass the two-resubmittal cap. They must identify specific issues, cite substantial evidence supporting the need for additional review, and document how the additional review addresses an adverse public health or safety impact.

For example, if San Diego DSD receives geotechnical reports during initial plan review indicating unanticipated soil instability near a coastal bluff, the agency could justify a third plan check resubmittal by documenting the specific geotechnical concern, citing the engineer's report as substantial evidence, and explaining how additional foundation design review addresses the identified stability risk.

Conversely, vague requests like 'provide additional details' or 'clarify design intent' without specific health or safety documentation would not justify exceeding the two-resubmittal limit. This standard creates accountability while preserving agency authority to address genuine safety issues.

Preparing for AB 1621 Implementation: Contractor Action Steps

While AB 1621 has not yet become law, Pacific Beach contractors can take several steps now to prepare for potential implementation in 2027 and maximize benefits from the two-resubmittal cap:

Submit Complete Applications: The quality of your initial permit application matters more than ever under AB 1621's framework. Incomplete submissions that require fundamental revisions consume one of your two allowed resubmittals, leaving less margin for substantive design issues. Invest time in thorough plan preparation, accurate site surveys, and comprehensive supporting documentation before initial submission.

Document All Agency Communications: Keep detailed records of every plan check comment, correction request, and agency communication throughout the permit review process. If AB 1621 becomes law, this documentation will be essential for challenging excessive resubmittal requests or pursuing Housing Accountability Act remedies when timelines are violated.

Request Consolidated Feedback: When receiving initial plan check comments, explicitly request that agencies provide all corrections and concerns in a single comprehensive review rather than piecemeal feedback. While agencies aren't currently required to consolidate comments, establishing this expectation now prepares for AB 1621's framework where multiple fragmented reviews would consume the two-resubmittal limit.

Understand Health/Safety Exception Criteria: Familiarize yourself with what constitutes legitimate health and safety concerns that might justify additional reviews beyond the two-resubmittal cap. Structural integrity, seismic safety, fire protection, accessibility, and coastal hazard protection are clear categories where agencies have documented authority to require thorough review.

Monitor Legislative Progress: Track AB 1621 through final Senate passage and gubernatorial action. If signed into law with a January 1, 2027 effective date, permits submitted in late 2026 may fall under the new framework. Understanding the implementation timeline helps with strategic project scheduling.

Comparison to Other Recent Permit Streamlining Legislation

AB 1621 is part of a broader California legislative effort to streamline housing permit processing and close loopholes that allow indefinite delays. Several complementary bills passed in recent years create a comprehensive framework for accountability:

AB 253 (2025): Allows home builders to hire licensed third-party reviewers if local governments cannot complete permit review within 30 days. Once third-party review is complete, agencies have 10 days to issue the permit or explain non-compliance issues. This provides an alternative pathway when agencies face capacity constraints.

AB 660 (2025): Makes violations of postentitlement permit provisions actionable under the Housing Accountability Act, establishing that failure to adhere to permit review timelines constitutes project disapproval. AB 1621 builds on this foundation by explicitly limiting resubmittal requests.

AB 1308 (2025-2026): Requires building departments to inspect residential construction projects within 10 business days of receiving notice of completion, categorizing inspection delays as Housing Accountability Act violations. This addresses the back-end inspection bottleneck that AB 1621 targets at the front-end plan review stage.

AB 462 (2025): Requires coastal development permits for ADUs to be approved or denied within 60 days, reducing typical coastal permit timelines from 6-18 months to 60 days concurrent review. For Pacific Beach coastal ADU projects, AB 1621's building permit streamlining would complement AB 462's coastal permit reforms.

Together, these bills create accountability throughout the permit lifecycle: plan review (AB 1621), inspection (AB 1308), coastal permits (AB 462), and third-party review options (AB 253). The comprehensive approach signals legislative commitment to addressing California's housing production challenges through procedural reform.

Potential Challenges and Implementation Considerations

While AB 1621's 67-0 Assembly vote and Senate Appropriations approval indicate strong support, several implementation challenges may arise:

Agency Capacity Constraints: San Diego Development Services and other local building departments already face significant workload pressures. The two-resubmittal cap may require agencies to invest in more thorough initial plan reviews to identify all issues upfront rather than discovering problems across multiple review cycles. This front-loaded review approach demands additional staff time per application.

Health/Safety Exception Interpretation: The standard for invoking the health and safety exception—'written findings based on substantial evidence addressing specific, adverse impact on public health or safety'—will likely generate disputes between applicants and agencies. Courts may need to clarify what constitutes 'substantial evidence' and 'specific adverse impact' through early litigation.

Coastal Permit Coordination: Pacific Beach, La Jolla, and other coastal projects often require coordination between local building departments, the California Coastal Commission, and regional water quality boards. The two-resubmittal cap applies to local agencies' building permit reviews, but interagency coordination complexity may challenge the streamlined timeline.

Transition Period Uncertainty: If AB 1621 becomes law, permits already in process when the bill takes effect may create ambiguity. The legislation would likely include provisions clarifying whether in-process applications are grandfathered under old rules or immediately subject to the two-resubmittal cap.

Database and Tracking Systems: Agencies will need updated permit tracking systems to monitor resubmittal counts, document health/safety exceptions with substantial evidence, and generate reports demonstrating compliance with AB 1621's requirements. Information technology upgrades may require additional municipal investment.

Despite these challenges, the bill's bipartisan support and California Building Industry Association sponsorship suggest broad consensus that current unlimited resubmittal cycles undermine housing production and require reform.

Conclusion: Predictable Timelines and Reduced Costs for Pacific Beach Builders

AB 1621 represents California's most direct legislative response yet to the permit bureaucracy that has plagued housing construction for decades. By limiting plan check resubmittals to two maximum unless documented health and safety concerns exist, reducing appeal timelines by 50%, and closing permit shot clock loopholes, the bill creates enforceable accountability for local building departments.

For Pacific Beach, La Jolla, and Mission Beach contractors navigating San Diego Development Services permit reviews, AB 1621 promises predictable timelines, reduced carrying costs, and relief from the endless resubmittal cycles that currently add months and thousands of dollars to ADU, remodel, and new construction projects.

The bill's 67-0 unanimous Assembly passage on April 27, 2026, and Senate Appropriations Committee approval on August 13, 2026, signal strong bipartisan momentum toward final passage. If signed into law with the anticipated January 1, 2027 effective date, AB 1621 will fundamentally reshape how California processes housing permits.

Contractors should begin preparing now by submitting thorough permit applications, documenting agency communications, and understanding the health/safety exception criteria. While AB 1621 has not yet become law, its advancement through the legislature demonstrates that California is finally tackling the permit delays that have undermined housing production and affordability for far too long.

Pacific Beach Builder will continue monitoring AB 1621's progress through final Senate passage and gubernatorial action, providing updates on implementation timelines and practical guidance for leveraging the new framework once it becomes law.
