Then please get involved and help shape public policy that will directly impact the look and feel of all future homes in LA.

Over the past six months an ad-hoc working group of over a dozen AIA-member architects has been working together to review the proposed changes that the Department of City Planning will make to the citywide Baseline Mansionization Ordinance (BMO/ BHO).  The BMO/ BHO effects the size and shape of all single-family residential construction projects citywide.  The ad-hoc working group’s primary concern is that the current proposal that is being offered by Department of City Planning will do more harm than good and will not achieve the results that the City is hoping to achieve to  curtail the development of oversize houses.  The attached letter shares several technical recommendations that the ad-hoc working group would like to share.

If you share these same concerns, then please write directly to your Councilmember and to the Department of City Planning with your professional input.  

Please submit comments by June 10, 2016 to: Niall Huffman at and copy Will Wright (

In order to be considered in the report to the City Planning Commission, comments should be received by June 10, 2016.  Comments received after June 10, 2016 should be addressed to the City Planning Commission for its consideration.
