Why this comparison matters
A zoning analysis done wrong or done late causes redesigns. The most common failure is not reading the code incorrectly; it is not reading it at all before schematic design starts. Zoning research is time-consuming enough that many firms do a quick check and miss overlay zones, state law overrides, or recent ordinance amendments that change what is actually buildable.
Step-by-step comparison
Same task. Different workflows.
The manual way
With TrussNote
Find the APN and zoning designation
Look up the Assessor Parcel Number on the county assessor portal. Navigate to the city or county GIS zoning map. Search the parcel to find its base zoning designation. Check for overlay zones separately.
Find the APN and zoning designation
Enter the address. TrussNote returns the APN, base zone designation, and all applicable overlay zones from the jurisdiction database.
Pull development standards
Open the municipal zoning ordinance to the chapter for the identified zone. Find the development standards table. Manually transcribe setbacks, height limit, FAR, lot coverage, and minimum lot size.
Pull development standards
The full development standards table is returned in structured format: setbacks by direction, height limit, FAR, lot coverage, minimum lot dimensions, and open space requirements.
Research permitted uses and parking
Find the use table for the zone. Identify whether the proposed use is permitted by right, requires a conditional use permit, or is prohibited. Then find the parking ratio table and calculate required spaces.
Research permitted uses and parking
Permitted uses, conditional use requirements, and parking ratios for the proposed use type are returned with direct ordinance citations.
Check for recent amendments
Search the city council meeting records for recent zoning ordinance amendments. Check whether any state housing laws override local zoning. This step is frequently skipped due to time.
Check for recent amendments
Recent ordinance amendments and applicable state law overrides (including AB 2011, SB 9, and ADU laws in California) are flagged automatically.
What you end up with
Manual approach
- Hand-transcribed notes from the ordinance
- No citations unless added manually
- Frequent gaps in overlay zone research
- State law overrides often missed
With TrussNote
- Structured zoning report with all development standards
- Ordinance citations for every data point
- Overlay zones and special districts identified
- State law overrides and recent amendments flagged
