Managing Disaster Recovery for Redlands Historic Commercial Buildings

Redlands is one of the Inland Empire's most architecturally significant cities. Its historic downtown, centered around State Street and Orange Street, features commercial buildings dating back to the late 1800s and early 1900s — brick masonry structures, Victorian-era storefronts, and early 20th-century civic buildings that give the city its distinct character.

When a disaster — fire, water damage, or earthquake — strikes one of these historic structures, restoration requires a fundamentally different approach than modern construction. The materials, construction techniques, and preservation requirements create challenges that standard restoration contractors aren't equipped to handle.

This guide is for historic property owners, municipal facility managers, and HOA boards in Redlands who need to navigate disaster recovery while preserving architectural integrity.

Why Historic Buildings Require Specialized Restoration

Materials Differences

  • Solid brick masonry: No cavity walls or weather barriers. Water that penetrates the brick stays in the wall until it evaporates.
  • Lime mortar: Older mortars are softer and more permeable than modern Portland cement mortar. Aggressive cleaning can damage joints.
  • Plaster walls: Lathe and plaster construction, not drywall. Water damage causes different failure patterns.
  • Old-growth wood: Denser and harder than modern lumber. Often worth restoring rather than replacing.
  • Lead-based paint: Present on most pre-1978 buildings. Requires EPA RRP-certified contractors for any paint disturbance.
  • Asbestos: Common in older buildings in floor tiles, pipe insulation, and joint compound.

Regulatory Considerations

  • Historic preservation codes: Redlands has historic preservation ordinances that may govern what can be modified
  • Secretary of the Interior's Standards: The federal standards for historic building restoration
  • California Historical Building Code: Provides alternative compliance paths for historic structures
  • Lead and asbestos regulations: EPA and Cal/OSHA requirements for handling hazardous materials in older buildings

Disaster Response for Historic Buildings

Water Damage in Historic Brick Buildings

Brick masonry absorbs water through capillary action. After water damage:

  1. Assess moisture depth: Use moisture meters designed for masonry to determine how deep water has penetrated
  2. Slow drying: Historic brick must dry slowly to prevent spalling (surface delamination). Rapid drying with heat can cause permanent damage.
  3. Monitor mortar joints: Water can dissolve lime mortar, requiring repointing after drying
  4. Check for efflorescence: Salt deposits on the surface indicate water migration through the brick
  5. Interior plaster: Plaster walls may take weeks to fully dry. Remove damaged sections carefully to preserve underlying lath.

Fire Damage in Historic Buildings

Fire damage in historic structures presents unique challenges:

  1. Soot removal from brick: Use gentle, non-abrasive methods. Aggressive cleaning can damage the brick surface.
  2. Smoke odor in old wood: Old-growth lumber is very porous and absorbs smoke deeply. Ozone treatment and thermal fogging may be needed.
  3. Lath and plaster: Fire-damaged plaster may need to be replaced, but lath can often be salvaged.
  4. Historic woodwork: Trim, doors, and architectural details may be irreplaceable. Prioritize restoration over replacement.
  5. Lead and asbestos disturbance: Fire damage can expose or disturb these materials. Testing before demolition is essential.

Earthquake Damage

Redlands sits in a seismically active region. After a significant earthquake:

  1. Structural assessment: Hire a structural engineer experienced with historic masonry
  2. Brick inspection: Check for cracked, displaced, or loose bricks
  3. Mortar joint assessment: Look for separation and cracking
  4. Chimney inspection: Historic chimneys are particularly vulnerable
  5. Seismic retrofitting: Consider retrofitting during restoration to improve future earthquake resistance

Working with Preservation Authorities

Before beginning restoration on a historic building in Redlands:

  • Contact the Redlands Planning Department to determine if the property has historic designation
  • Determine if the Secretary of the Interior's Standards apply
  • Identify which modifications require preservation commission approval
  • Document existing conditions before any work begins

Choosing a Restoration Contractor for Historic Buildings

Key qualifications:

  • Experience with historic building restoration
  • EPA RRP certification (required for pre-1978 buildings)
  • Asbestos and lead testing capabilities
  • Understanding of lime mortar repointing
  • Familiarity with the California Historical Building Code
  • Proper insurance for historic building work

FAQ

Can I use modern materials to repair a historic building? Not always. Historic preservation standards may require period-appropriate materials. Modern Portland cement, for example, can damage historic brick by trapping moisture.

Do I need special permits for restoring a historic building in Redlands? If the property has historic designation, you may need approval from the preservation commission before making modifications.

Can I dry historic brick walls with heat? No. Rapid drying can cause brick spalling and mortar damage. Historic masonry must dry slowly and naturally with controlled ventilation.
