Dormer addition sought for houses on small lot in mixed-use zone

The applicant wants to renovate existing houses and add a dormer on a 0.19-acre site. Because the development no longer meets current zoning, the city must confirm its legal nonconforming status; the expansion would be under 20%. No change in units or parking is planned.
