Summary
Medford caps building footprint as a share of lot area under Section 10.710's site development table, with the ceiling set by both zoning district and housing type. Detached single-family homes are held to 50 percent lot coverage across every residential district from SFR-00 through MFR-15.
Lot Coverage (percentage) ... Lot coverage may exceed the percentages below when the total building footprint of a detached SFR or duplex is not more than 2,000 square feet. Detached SFR: 50 percent [SFR-00, SFR-2, SFR-4, SFR-6, SFR-10]. Duplex: 50 percent [SFR-2 through MFR-20]. Townhouse: 75 percent [SFR-4 through MFR-20]. Triplex: 60 percent [SFR-4, SFR-6, SFR-10], 65 percent [MFR-15], 70 percent [MFR-20]. Cottage Cluster: No maximum lot coverage allowance.

Full Breakdown
710-1, tied to the zoning district (SFR-00, SFR-2, SFR-4, SFR-6, SFR-10, MFR-15, MFR-20, MFR-30) and the type of housing being built. A detached single-family residence may cover no more than 50 percent of the lot in every one of those districts. Duplexes are capped at the same 50 percent in SFR-2 through MFR-20. Townhouses get a higher allowance, 75 percent, in SFR-4 through MFR-20, while triplexes and quadplexes are capped at 60 percent in SFR-4, SFR-6 and SFR-10, rising to 65 percent in MFR-15 and 70 percent in MFR-20.
Multifamily buildings of five or more attached units follow the same tiered scale: 60 percent in MFR-15, 65 percent in MFR-20 and 70 percent in MFR-30. 818A's separate cottage cluster standards. The table also builds in a footprint bonus: coverage may exceed the listed percentage for a detached single-family home or duplex whenever the total building footprint does not exceed 2,000 square feet, letting smaller, denser homes exceed the district's normal ceiling. 706 supplies the companion formula the Planning Department applies once the applicable percentage is identified: maximum coverage (MC) equals lot area (LA) multiplied by the district's coverage factor (cf), expressed as MC = LA(cf).
836: an ADU may push the primary parcel's lot coverage up to 10 percent above the otherwise-applicable limit, but only for the ADU's own footprint, not for any other structure on the lot.
Violations & Fines
A building permit application that shows a footprint exceeding the Table 10.710-1 percentage for its district and housing type will be rejected by the Building Safety Department at plan review, since compliance with Chapter 10's site development standards is a prerequisite to permit issuance. An owner who builds over the limit without approval faces the same code enforcement path as any other Land Development Code violation: a correction order from the City, followed by citation if the excess coverage is not remedied or approved through a variance or the Section 10.707(1)(e) setback-adjustment process where applicable.
