Sterling/lilac Ave The zoning "RS" suggests the lot is intended for single-family residential use under current rules. Because it's a sizable lot (~1.8 acres), there may be opportunities for custom build, subdivision (depending on local zoning/subdivision rules), or other development though you'd need to verify with the city. Being vacant means you'd likely have some of the development costs (infrastructure, utilities, permitting) ahead if you plan to build. The listing price gives you a benchmark for current market value in the area. The APN allows you to pull more official documentation (lot map, legal description, zoning overlays, etc) from the county assessor's or planning department database.
