| Required 
<br />Existing exterior building materials shall be retained.  Deterioration of wood materials shall be prevented through repair, cleaning, and 
<br />painting.  The existing architectural detail around windows, porches, doors, and eaves should be retained or replaced by replicas of the same 
<br />design and materials when deteriorated beyond repair.   
<br />Masonry structures shall be maintained, tuckpointed and properly cleaned when necessary.  Masonry shall be cleaned only when necessary to 
<br />halt deterioration or to remove stains, and shall be done with the gentlest method possible, such as low pressure water and soft natural bristle 
<br />bushes. 
<br />Stucco surfaces shall be maintained by cleaning and repainted when necessary.  When repairing stucco a stucco mixture shall be used. 
<br />Recommended 
<br />Whenever possible, the original building materials should be restored.   
<br />Aluminum or vinyl siding may be used when it is the only feasible alternative to maintaining the original surface material.  When used over 
<br />wood surfaces, this siding should be the same size and style as the original wood.  However it must be noted that such material can contribute 
<br />to the deterioration of the structure from moisture and insects. 
<br />Mortar joints should be repointed only when there is evidence of moisture problems or when sufficient mortar is missing to allow water to 
<br />stand in the mortar joint.  Existing mortar shall be duplicated in composition, color, texture, joint size, method of application, and joint 
<br />profile. 
<br />Prohibited 
<br />Wood siding shall not be resurfaced with new material, such as artificial stone, brick veneer, asbestos or asphalt shingl es, which is 
<br />inappropriate or was unavailable when the building was constructed.  Sandblasting or the use of harsh detergents shall not be used on 
<br />masonry or stucco.  This method of cleaning erodes the surface material and accelerates deterioration. 
<br />Not Re commended 
<br />Waterproof or water repellant coatings or surface consolidation treatments should not be used unless required to solve a specific problem that 
<br />has been studied and identified.  Coatings are frequently unnecessary, expensive, and can accelerate deterioration of the masonry.  Mortar 
<br />joints which do not need repointing should not be.  Repointing should not be done with mortar of high Portland cement content, which can 
<br />often create a bond that is stronger than the building materials.  This can cause deterioration as a result of differing coefficient of expansion 
<br />and the differing porosity of the material and the mortar, which can result in serious damage to adjacent brick.  Paint shoul d not be removed 
<br />from masonry surfaces indiscriminately. 
<br />[…] 
<br />b. WINDOWS AND DOORS 
<br />Windows and door frames are in nearly all cases wood.  Brick structures have stone sills and brick lintels; masonry block structures have 
<br />masonry sills and lintels.  In some cases where aluminum siding has been applied window trim has been covered.  About half of the 
<br />structures in the district have aluminum storm windows, the other half wood storm windows.  
<br />Required 
<br />Original windows and doors including sash, lintels, sills, shutters, decorative glass, pediments, hoods, and hardware shall be retained 
<br />or when deteriorated beyond repair, replaced with duplicates of the existing or original. 
<br />Recommended 
<br />Wood frame storm windows and doors, painted to match the existing or original, should be used but should not damage existing frames and 
<br />should be removable in the future.  If new sash and doors are used, the existing or original materials, design, and hardware should be 
<br />used.  When metal storm doors are used, they should be painted anodized or coated to match the existing.  When awnings are used they 
<br />should be of canvas material. 
<br />Prohibited 
<br />Existing or original doors, windows, and hardware shall not be discarded when they can be restored and re-used in place.  New 
<br />window and door openings which would alter the scale and proportion of the building should not be introduced.  Inappropriate new 
<br />window and door features such as aluminum insulating glass combinations that require the removal of the original windows and 
<br />doors shall not be installed. 
<br />Not Recommended 
<br />Metal, vinyl, or fiberglass awnings, hoods, and fake shutters that would detract from the existing character or appearance of the building 
<br />should not be used.

<br />SITE VISIT REPORT:  
<br />Administrator Toering and Inspector Van Overberghe visited the site on August 19th, 2021 to discuss the proposed 
<br />project of adding a new entrance door to the south-east river-facing façade of the structure.  Potential window and 
<br />door configurations were discussed, as well as how they would interact with the riverfront and the yard.   
<br />  
<br />STAFF RECOMMENDATION: Staff recommends approval.
