Multiple-family residential; 1000 sf per dwelling unit; also allows all land uses of the C-1 district
What you may build in R-5
Every verdict below is the base-district answer read out of the
ordinance of record, with the section that says so. A use with no row is shown as
unknown rather than folded into “no”.

Not listed. R-5 imports the C-1 use list per 501.3.2, and self-storage is not permitted in C-1 either, so it is still prohibited
Multifamily
Allowed, but only with a discretionary approval

Capped in practice by the 1000 sf lot area required per dwelling unit (502); a single building of up to 4 units on one lot of record does not require a POD

DERIVED. This is the closest thing MCZO has to a mixed-use district: 501.3.2 states the R-5 district "also allows all land uses within the C-1 zoning district", so residential and C-1 commercial can coexist. Verify with the county before marketing it as mixed-use

Standards notes. Multi-family development requires a Plan of Development; a single building of no more than four units on one lot of record does not
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.
