MDR-18 dimensional standards.

These are the letter-of-the-law limits for the base MDR-18 district. Overlays (historic, neighborhood plan, and similar) can tighten them; a specific address check resolves the overlays that actually apply.

Sources

Every figure above is quoted verbatim from the current ordinance. We never substitute a typical-for-zone default: a field absent from the record shows nothing, not a guess.

    Informational only — not a permit, appraisal, or professional engineering opinion. Verify with your local planning department before acting on it. See Terms and data sources.
