Structure and building envelope<\/h2>\n<h3>Roofs<\/h3>\n<ul>\n<li>Residential: sloped shingles, visible wear and tear, attic ventilation<\/li>\n<li>Commercial: flat roof with layered membrane, water pooling areas, potential leaks that can\u2019t be spotted without proper testing<\/li>\n<\/ul>\n<h3>Foundations<\/h3>\n<p>Both building types present challenges, but commercial properties may require:<\/p>\n<ul>\n<li>Reinforced slabs for heavy machinery<\/li>\n<li>Deeper foundations<\/li>\n<li>Loading docks or drive-in access<\/li>\n<\/ul>\n<h2>2. Mechanical and technical systems<\/h2>\n<p>This is where the biggest gap lies between commercial and residential inspections.<\/p>\n<h3>Electrical<\/h3>\n<ul>\n<li>Residential: basic circuits, standard panels<\/li>\n<li>Commercial: three-phase systems, higher loads, specific rules for ventilation and equipment<\/li>\n<\/ul>\n<h3>Plumbing<\/h3>\n<ul>\n<li>Residential: visible pipes, standard water use<\/li>\n<li>Commercial: variable pressure, industrial drainage, more complex equipment<\/li>\n<\/ul>\n<h3>Ventilation &#038; air conditioning<\/h3>\n<ul>\n<li>Commercial buildings often rely on central ventilation, rooftop units (RTUs), or multi-zone systems.<\/li>\n<\/ul>\n[\/et_pb_text][et_pb_testimonial author=&#8221;Project Manager &#8211; Genispec&#8221; portrait_url=&#8221;https:\/\/genispec.com\/wp-content\/uploads\/2018\/05\/genispec-icon.png&#8221; quote_icon_color=&#8221;#036e8c&#8221; _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]\n<p>\u201cThese systems require a more in-depth look.

Building usage matters<\/h2>\n<p>The building\u2019s function also influences the inspection:<\/p>\n<ul>\n<li>Retail: check storefronts, floors, accessibility (e.g. wheelchair access), electrical setup<\/li>\n<li>Industrial: assess foundations, concrete slabs, storage areas, load-bearing capacity<\/li>\n<li>Offices: air quality, HVAC system performance, space layout<\/li>\n<\/ul>\n<p>Each usage type brings its own technical requirements and inspection checklist.<\/p>\n<h2>5. What general inspectors may miss<\/h2>\n<p>Residential building inspectors don\u2019t always have the authority or training to assess:<\/p>\n<ul>\n<li>The structural integrity of an industrial concrete slab<\/li>\n<li>The durability of a centralized mechanical system<\/li>\n<li>Whether a commercial property meets the right safety codes<\/li>\n<\/ul>\n[\/et_pb_text][et_pb_testimonial author=&#8221;Project Manager &#8211; Genispec&#8221; portrait_url=&#8221;https:\/\/genispec.com\/wp-content\/uploads\/2018\/05\/genispec-icon.png&#8221; quote_icon_color=&#8221;#036e8c&#8221; _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]\n<p>\u201cAs an engineering firm, the scope of our reports is much broader\u2014especially when lenders or insurance companies are involved,\u201d says the expert.<\/p>\n[\/et_pb_testimonial][et_pb_text _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]\n<h2>6.
