RV / boat storage
Unknown — this dataset has no row for it
No row for RV or boat storage in R1-18 in this dataset. That means unknown — go and look. It does not mean no.
How big you may build it
A blank cell means this dataset carries no number for that standard — read it as “go and look”, not as zero.

| Floor area ratio (FAR) | — | far |
| Maximum height | 35 ft | max_height_ft |

No district in this dataset publishes a floor area ratio: intensity in this code is governed by lot coverage, height and — for residential — density or minimum lot area per dwelling unit. See the metro page for the provenance note on that.

This is a base-district reading of the ordinance text, transcribed from the source below. It is not a Zoning Verification Letter, not a determination by the jurisdiction, not legal advice, and not a substitute for asking the planning department about a specific parcel. Overlays, recorded plan conditions, rezoning stipulations and parcel geometry are not checked here, and any one of them can change the answer on this page.
Verify locally before you spend money. Call the planning counter, pull the parcel's zoning-map designation and its case history, and confirm the section cited above still reads the way it reads here.
