The Step-by-Step Process for an SB9 Lot Split

Successfully completing a lot split under California’s SB9 law is a detailed, multi-phase process that requires careful planning, coordination, and professional management. At Riechers Engineering, we guide our clients through every step — from the initial eligibility check to the final recording of the new parcels.

Here’s an overview of the two major phases involved in an SB9 lot split:

Part 1: Tentative Parcel Map (TPM) Project Management and Approval

The first phase of an SB9 lot split focuses on preparing, submitting, and obtaining approval for a Tentative Parcel Map (TPM). This phase ensures that your proposed subdivision complies with city or county regulations.

Here’s how the process unfolds:

• Full Eligibility Assessment
  We conduct a thorough review of your property to confirm it qualifies for an SB9 lot split under state law and local ordinances. 
• Preparation of Affidavit and Application Documents
  We prepare all required affidavits and official application documents for your jurisdiction. 
• Title Guarantee Order
  We order and pay for a title guarantee to verify clear ownership and disclose any restrictions. 
• Evidence B-K Documentation
  We assemble all supporting documentation needed to demonstrate your property’s eligibility. 
• Submittal Requirements and Fee Determination
  We determine what your specific city or county requires for submittal, including applicable fees. 
• Lot Layout Consultation
  We work closely with you to finalize the proposed layout of the new parcels before drafting begins. 
• Drafting of Tentative Parcel Map
  Our team prepares the formal tentative parcel map in compliance with local mapping standards. 
• Application and Map Submittal
  We submit the completed application and tentative parcel map to the planning department. 
• Payment of City/County Fees
  We ensure that all required fees are paid promptly to avoid delays. 
• Project Management, Oversight, and Expediting
  From start to finish (typically 3–8 months, but timelines can vary), we manage the process, respond to city comments, and advocate for approval. 
• Environmental Coordination (As Needed)
  If required, we coordinate:
  • Biological assessments and reports
  • Wetland assessments and reports 
• Incompleteness Reviews and Re-Submittals
  If the city requests additional information, we quickly address comments and resubmit. 
• Client Communication and Support
  We provide monthly project status updates and remain available for client calls and questions throughout the entire process.

Part 2: Final Parcel Map (FPM) Project Management and Approval

After the tentative parcel map is approved, the project moves into the Final Parcel Map (FPM) phase — the formal recording process that legally establishes your new parcels.

This phase includes:

• Topographic and Boundary Surveys
  We complete detailed surveys required for final map drafting and certification.
• Reference Document Collection
  We outline the certificate sheet and order all necessary reference materials.
• Drafting of the Final Parcel Map
  Our team prepares a precise and legally compliant final map for city and county review.
• Preparation and Submittal of FPM Documents
  We compile and submit the final map package and pay any remaining submittal fees.
• Project Management, Oversight, and Expediting
  We manage this phase from start to finish (typically 5–10 months, depending on the city/county).
• Utility Coordination
  We obtain “Will Serve” letters from utility providers confirming service availability for each new lot.
• Engineering Plans (As Needed)
  If required, we coordinate:
  • Drainage plans and erosion control plans
  • Improvement plans for utilities, driveways, or other site needs
• Tax and Recording Coordination
  • Pay any required tax collector fees
  • Prompt you to pay property taxes based on assessor’s figures
  • Contact assessor’s office and pay assessor processing fees
  • Pay title company processing fees
• Easement Agreements (As Needed)
  We prepare any easement documents needed for access, utilities, or drainage.
• Final Map Signing and Recording
  • We order the mylar copy of the map, obtain notarized client signatures, and submit it for city signatures.
  • After all approvals, we pay the recording fee and officially record the final parcel map.

Why Professional Project Management Matters

An SB9 lot split involves dozens of steps, multiple agencies, and precise compliance with technical standards. Missing a small detail or a deadline can cause months of delays — or even jeopardize your project.
