Single-family semidetached dwellings, two-family duplex dwellings, and single-family attached dwellings may be developed without separate lots for each dwelling unit. In such cases, all of the dimensional standards outlined in § 405-504 above, except for minimum lot size and minimum lot width, must be met.

per dwelling unit in accordance with the following:

The following flexible dimensional standards are applicable to all
lots that meet any of the following conditions:

and nonresidential uses.
(2)
Alterations or additions to residential structures that do not
result in an increase in residential density.
(3)
New residential construction that is either equal to or at a
lesser density than existing conditions.
B.
The Borough of Lansdale Residential Design Review Manual, copies
of which are available from the Code Enforcement Officer of the Borough
of Lansdale, contains median lot size and setback data for all residential
neighborhoods and uses.
(1)
Lot area: The minimum lot area for each dwelling unit shall be the median of all lots on the block that are of the same residential use classification. Where fewer than two lots of the same residential use are located on the block, the lot area from § 405-504 (Standard dimensional criteria) shall be used.

Where fewer than two lots of the same residential use are located on the block, the lot width from § 405-504 (Standard dimensional criteria) shall be used.
(3)
Front yard: The minimum front yard shall be the median of all
lots on the block of the subject property that are a permitted use
in the district. In no case may the front yard be greater than 10
feet of the median. At least 75% of the front facade, at ground level,
must be located within the front yard setback area.
(4)

(a)
Single-family detached, two-family duplex: eight feet.
(b)
Single-family semidetached: six feet with no side yard for the

(3)
Major renovations to the front facade of buildings, which may
include but are not limited to a change in exterior surface materials,
new porches, enclosing porches, changes in the ratio of openings to
wall, rooflines, etc.
B.
Exceptions. Design standards for infill development shall not be
enforced for the repainting, repair, restoration or reconstruction
of existing features such as doors, windows and siding where such
work maintains the outer dimensions and surface relationships of the
existing structure. Design review is not required for the replacement
of doors, windows or other transparent surfaces, provided that they
are replaced with similar-looking materials that do not substantially
alter the front facade of the building.
