About this data
- Neighborhood pages cover 2018 onward: City of San Diego Development Services Department permits located in this community planning area, the city's official neighborhood boundaries, which may not match every local definition of the neighborhood. Build type is classified automatically from permit descriptions.
- Costs are declared permit valuations (single-ADU permits only), not final construction costs.
- The city closes a permit both after its final inspection and after it expires, and its data doesn't say which, so this page doesn't estimate how many permits were finished. Closed permits stay in the counts.
