What Is a Lot of Record in Zoning?
What is a lot of record? A lot legally created by a recorded plat or deed before current zoning rules, which may still be buildable even if it is small.
What is a lot of record? A lot of record is a lot that was lawfully created and recorded, by plat or deed, before current zoning or subdivision rules took effect. Many zoning codes allow a lot of record to be built on even if it no longer meets today’s minimum size, width, or frontage, as long as other standards like setbacks can be met. Codes define the term differently, and some require that adjoining lots under common ownership be combined. This page is general land-records background, not legal advice.
Why it matters
When a city adopts or raises minimum lot sizes, older lots may become substandard. Without lot-of-record protection, those lots might be unbuildable. Lot-of-record provisions recognize that owners relied on the earlier rules.
Typical code language
| Element | Common rule |
|---|---|
| Created legally | Recorded before a specific date or ordinance |
| Separate ownership | Sometimes required as of the ordinance date |
| Setbacks | Must still be met, sometimes reduced |
| Use | Usually limited to single-family on residential lots |
Merger of substandard lots
Many codes include a merger rule: if two or more adjoining substandard lots are owned by the same person, they may be treated as one lot for zoning. This can prevent building on each one separately. Merger rules vary widely, and some states restrict them by statute.
Lot of record vs nonconforming use
A nonconforming lot concerns lot size or dimensions; a nonconforming use concerns how the property is used. Both are protected in some ways by grandfathering. See what is a legal nonconforming use.
Lots vs parcels
A tax parcel is not necessarily a lot of record. Assessors may combine or split parcels for tax purposes without creating legal lots. See lot vs parcel vs tract.
How to confirm
- Find the recorded plat or deed that created the lot.
- Check the date against zoning ordinance history.
- Review ownership history for merger issues.
- Ask the zoning office for a determination or zoning verification letter.

When a variance is needed
If the lot cannot meet setbacks or other standards, the owner may need a variance. See what is a zoning variance.
Buying a small lot
Before buying a vacant lot that looks small for its district, confirm its lot-of-record status and whether utilities and access are available.
Common situations
Older beach and lake communities often have 25-foot or 40-foot lots platted in the early 1900s, long before modern zoning required 60 feet or more. Rural counties may have small tracts deeded off farms before subdivision rules existed. In both cases, the lot-of-record provision is what makes a house possible. The answer often turns on dates: when the lot was created, when the zoning changed, and who owned the neighboring lots at that time.
Bottom line
A lot of record is a lawfully created and recorded lot that predates current rules and may still be buildable despite not meeting today’s size or frontage minimums. Merger rules, setbacks, and local definitions matter, so confirm with the zoning office. Find county records via the Platbookmapper map.
