01
Show emergency access on the site plan
Construction adds temporary risks: stored materials, open trenches, blocked paths, hot work, occupied-home protection, and temporary utility conditions. Plan controls with the sequence.
Draw the path from the street with gates, projections, buildings, and grade changes. Field measurements should support the clearances shown on paper.
02
Keep the route usable during construction
Smoke and carbon-monoxide alarms, fire-resistance details, egress, and addressing belong in the coordinated documents. Do not rely on a generic checklist alone.
Trenches, lumber, bins, and parked vehicles can block a route that looked clear before work began. Set staging limits and maintain access for the occupied home.
03
Coordinate alarms, openings, and separation
Anaheim Building and Fire staff determine applicable requirements. Ask early when the site presents narrow access, unusual separation, or hillside conditions.
Window placement, eaves, wall assemblies, smoke alarms, carbon-monoxide alarms, and addressing belong in the same coordinated drawing set.
04
Ask early when the lot is unusual
Narrow side yards, hillside conditions, or close building relationships deserve a City conversation before the layout and price become difficult to change.
