WINTER WEATHERIZATION INSPECTIONS


Rental weatherization inspections are required at the time of property transfer!

  1. The residence is exempt if it has been constructed on or after December 1, 1978 and has 1 or 2 units and has "never" been issued a certificate of compliance and will not be occupied by the owner.

  2. The residence is exempt if it has been constructed on or after April 15, 1976 and 2 to 4 units and has "never" been issued a certificate of compliance and will not be occupied by the owner.

  3. The residence is exempt if it has been constructed on or after April 15, 1976 and has 4 units or more and has "never" been issued a certificate of compliance. "It makes no difference if it is owner occupied or not".

  4. Mobile Homes are exempt.

Contact me to set up an inspection if the residential property does not fit the above criteria.


What the Inspection Criteria's are!

The following requirements were updated as of Dec 1 2008 with new regulation changes.

  1. Doors need to be insulated doors or else non-insulated with a storm door with self closing devise. Needs double glazed windows or storms on side lites.

  2. Windows need to be insulated or single pane glass not cracked or broken with storms and tight fitting with putty in place in the building envelope and basement.

  3. Storm window caulking or storm window glazing needs to be in place where required.

  4. Weather stripping for exterior storm door cracks larger than 0.1 inches.

  5. Blower door testing can be requested but is usually not done. "This is to justify not doing other certain envelope air leakage repairs." It also will need to be done by a weatherization contractor".

  6. Box sills "where accessible need" R-19 insulation if possible or R-11 if space is limited.

  7. Forced air ducts in a vented crawl space need R-5 insulation.

  8. Steam heating pipes in vented crawl space need R-4 insulation.

  9. Hot water heat pipes in vented crawl space need R-2 insulation.

  10. Domestic water pipes in vented crawl space need at least R-2 within 5' of a water heater. (It may be prudent to do more than the requirements).

  11. Shower flow restrictors 3 GPM max. (1 quart in under 5 seconds meets criteria)

  12. Attic hatches need R-5 for side doors and R-19 for over head hatches where they are located within the heating envelope.

  13. Attic insulation if under R-19 needs to be brought up to R-38 or maximum allowable which ever is less.

  14. Attics where accessible need upper and lower venting to split to equal 1 sq ft of venting per 300 sq feet of attic floor surface area. Crawl spaces that are vented need a vapor retarder.

These things can possibly be checked by you prior to me visiting the residence and corrections then also could be done to save time and a return trip.
