Every lot's limits, quoted, before you draw a line.
Check a client's lot in a minute: what it can hold, where the building can go and the building code that applies, with every rule quoted so nobody has to take your word for it.
The lot
- Homes allowed, floor area ratio, height and setbacks, with narrow-lot and taller-ADU rules
- Every way to build: by right, ADUs and Bonus ADUs, SB 9 splits, the state density bonus and City programs
- Overlays that change the answer: coastal, fire hazard, transit areas, historic districts, airport zones
- Save, share and download each lot you check
The code
- The 2025 California codes and the San Diego Municipal Code, searchable by section or plain question
- Answers to code questions with every citation checked against the code library
- A quick plan check against the zone's numbers and the residential code
- Project checklists drafted from the code sections that apply
The plans
- Mark up plan sets, add comments and share them with the team
- Projects that keep each lot, its checks and its drawings together
- The building code section for each ADU kind, written in plain English
- Permit fee estimates from the City's fee schedule
The rule, not a summary of it.
When the report gives a setback, the sentence and section come with it, ready to drop into your plan notes or a reply to a correction.
“The minimum street side yard setback of an ADU shall be 4 feet or the minimum street side yard setback of the base zone, whichever is less.”
