What the site adds
Historic-district review, raised foundations, crawlspace access, and salt-air corrosion on existing hardware can all lengthen a project before work even starts.
What belongs in the scope
Panel work, transfer equipment, materials, disposal, and startup testing should be written down, not assumed.
When a permit or specialist gets involved
BAR review, floodplain permitting, and utility coordination can pull in extra time or an additional trade. Confirm current rules with the city and the provider.
