Renters, Landlords, and Mold
Mold problems in buildings are a result of water and moisture problems. Renters need to operate the heating and ventilation systems to reduce water condensation. Renters need to notify landlords promptly, in writing, of any water leaks or moisture problems. If there is a water leak or moisture problem, it should be fixed by the landlord. Your local building and code enforcement official may take action if building problems are not addressed - they won't respond to mold complaints, so it's important to stress the source of the water problem.
Landlords are responsible for maintaining rental units, including fixing building problems such as water leaks and ventilation or heating defects which may lead to moisture problems. Landlords must notify their tenants about the health hazards associated with exposure to indoor mold and ways to control mold growth in their dwelling units. Posting this information in a visible, public location at the dwelling unit property is allowed. The following materials can fulfill the notification requirements:

Example of Remediation for Attic Mold in Seattle
Date of Remediation: Jan. 25th, 2011
- Inspection of attic revealed moderate mold growth throughout significant areas of attic sheathing. At this time, the mold growth has led to some structural damage, and is an indication of a failure of the home to adequately exhaust damp air created by the occupants.
- Elevated moisture noted throughout significant portions of the attic sheathing. It is necessary to thoroughly dry the framing and sheathing prior to the application of encapsulant.
- No obvious roof leaks were observed on inspection of the attic. Environix is not a professional roofing contractor and cannot guarantee the condition of any roofing structure.
- Insulation has been saturated and must be removed.
- Insufficient ridge area ventilation installed throughout attic. This limits the exhaustion of humid air through the roof assembly.
- Insufficient soffit ventilation throughout the attic. Existing ventilation blocked by improperly installed insulation. This limits the influx of fresh air through the soffit vents, leading to excess condensation and mold growth. It is recommended that blocked soffit vents be cleared and all soffit venting be protected by the appropriate baffling.
- Proper ventilation is necessary to minimize condensation and subsequent mold growth. All areas of elevated moisture or improper ventilation must be addressed to ensure the effectiveness of our process. Current code calls for 1sqft net free area of ventilation for every 300 square feet of attic space, distributed evenly between the ridge and soffit area.
- The ceiling currently lacks proper air sealing, allowing excess moisture and heat to escape into the attic area. This air leakage is a key cause of energy loss, attic condensation and mold growth.
- The exhaust ducting from the bathroom fan, whole house fan and/or kitchen range exhaust hood is not appropriately venting to the exterior. This condition allows warm moist air to flow into the attic and is likely a contributing factor in condensation. It is necessary for all exhaust ducting to vent completely to the exterior through insulated ducting and be connected to a dedicated roof jack with appropriately sized collar.
Trash and debris:
- The attic is currently free from excessive amounts of trash and construction debris.
- The property is heated primarily by electric wall heaters or radiant hydronic heating.
- Homes that are not equipped with a forced air heating system must have special care taken to ensure appropriate ventilation, and prevent the buildup of humidity and other pollutants.
- Current standards recommend 0.35 to 0.7 air changes per hour, this may be attained by installation of a ducted heat recovery ventilator or upgrading mechanical exhaust ventilation to function on a continuous flow (the recommended units for this method is a Panasonic Whisper Green exhaust fan).
- The estimated square footage of this home is 1700 sq.ft.
- The necessary flow rate to establish 0.35-0.7 ACH for this home is 90-180CFM.
- The home is equipped with an exhaust fan above the laundry fixture that has been set on a timer. At the time of inspection the timer had been deactivated.
- To achieve the necessary ventilation 2 of the existing exhaust fans can be replaced with a Panasonic Whisper Green 80CFM exhaust fan set to run at 50CFM continuous flow and for 60 minutes at 80CFM once the motion-sensor has been activated.
- Roofing contractors have informed the home owners that the roofing should be replaced, it will be most cost-effective to remove all wet and/or contaminated sheathing at this time.
- All insulation should be removed as has been saturated.
- Protective baffles should be installed to prevent insulation from blocking the soffit vents.
- The vaulted portion of the attic may need to have batt insulation installed as thick as possible while the roof is off. Contrator must ensure that appropriate ventilation is maintained.
- All possible penetrations should be sealed using expandable foam, in accordance with standard air-sealing procedures.
- Appropriate ventilation should be installed in the attic to ensure that moisture does not return to the attic.
- All exhaust fans should be ducted fully to the exterior via insulated ducting and connected to dedicated roof jacks. Roof jacks should be placed as close to the exhaust fans as is feasible.
- Once the roof has been replaced and all insulation removed the few remaining areas of wet building materials (rafters and gable walls) can likely be dried by the home owners using fans and heaters.
- Once the wet building materials have been thoroughly dried, Environix can perform the 2-stage remediation process listed above in select areas of remaining contamination.
- Once the all work has been completed the flat portion of the attic should be insulated to industry standards of no less than R-38.

Evictions skyrocket, along with complaints of crummy rentals
By VANESSA HO
The young couple and their dog were living in the crawl space of a South Park building, with dirt floors and not enough ceiling height to stand upright. The rent? About $300 a month.
Another tenant, a college student in the University District, was renting a tiny furnace room as her living quarters, until she twice went to the hospital with carbon monoxide poisoning.
Those were just two cases handled by Seattle's Department of Planning and Development, which saw a small rise in the number of substandard housing calls and a huge rise in eviction complaints.
The trends, referenced in a department briefing this week, spoke to the continuing, painful fallout of the Great Recession. Housing advocates said foreclosures, continuing joblessness, and a lack of affordable housing have led to a massive increase in evictions, and a steady stream of tenants living in dangerous conditions.
Last year, the city's Planning and Development department, which enforces building codes, saw a doubling in calls about evictions. Some of the increase came from better record keeping, said Karen White, director of the department's code compliance division. Read more.
