to find. there's an 1869u sds,ge odectic, service map representation that's somewhat accurate, not where lots are provided but there's a little black dot and the whole thing is about 24 inches by 30 inches and covers the whole city. so it's not fine grained but you can say there was blob there in 1869. >> do they have this many the history room? >> yes. if you do a web search you can find it on-line. there's one source where you can actually like zoom in and

there's another,us coast map from the 1850s but i would think pretty much any building from the 1850s is already kind of done. >> this gentleman has a question? >> are they consistent block numbers from year to year and agency to agency. >> they have changes. when the original city was layed out by the city surveyor it was called the 50 bar survey. when it was expanded to market. so up until the teens the city kept those as separate surveys and theres the different surveys in the outside lands which is sort of the western part of the city. >> the uninhabitable part of san francisco. >> they were different surveys

and blocks in those. mission block 38 and then in the 19 teens or 20s everything was consolidated into the big block and lot list. so mission block 32 became block 3927 or something like that. >> this is a good time to put a plug in on the san francisco public library history room. on page 38 you will find a document how to research your san francisco building. they have lots of references to other agencies but quite frankly the san francisco history room in the san francisco library is a fantastic resource and people there are extraordinarily knowledgeable. and page 14 talks about when the photo collection is open. you have to wear white gloves

and can look at a couple at a time and they will often have photos of your block or neighborhood or the ones that are fascinating and part of your collection as well. >> my experience with that resource has been really excellent over the years. they really take a lot of pride in the collection and get excited when somebody wants to use it. i encourage you to use these people as a resource. the street photographs are not the only resource for photographs that are really invaluable. they have a lot of news related photograph ss that are indexed sometimes by dris strict or street but never by address but that does not mean you won't see the address your after. san francisco heritage located

in the,li z, 200 franklin street, 441 -- 3000. they have original print version of the sand born map from 1830s. building files and files on architects that practices in san francisco and major contractors that worked in san francisco their biographies and certain indexes that are not available else where. so i would suggest contacting them. >> and joining. it's a nonprofit organization that preserves san francisco heritage. >> okay i want to flip through some of these other materials

we brought along to show you. not the building codes. here today, fantastic book you want to tell us about it. >> here today, is the end results of years worth of research done by the junior league of san francisco. a book published in the late 1960's and there's an enormous volume of research. architecture, social that went into the making and not every building researchs in the making of this book is published. there are background files that san francisco library history room, the planning department has an index but the library has on their web page the index you can download some you can go by the street and check to see if the number of your

buildings listed and they will have a research file on that building. >> -- just to mention i have in, my here today, copy the resolution of boardrd of supervisors adopted this as an official list of resources in that time. so if you have your property lists or even in the back where there's a listing of olive street all of the shingles are a later addition it maintain as purity of line. especially is the blind window on the side. if your buildings listed in one of these your a qualified historical resource and you may use the space historical building code which provided alternatives to the other building code requirements and this is a great resource for us

to approve the most important resources in the city. >> if that window needs to be repairs whoa to you. >> i get a lot of requests to use the state historic building code. it's called the san francisco golden age postcards and we had a copy of this and i suddenly realized a lot of people came in and they're not listed but i have this wonderful old photograph from wherever it might be. 1930s and i can use this to help document that it's appropriate to use the state historic cold or code and it's showing every aspect. old cable cars and when they were taken out officer vice and put out on the beach to make little houses and all over the

city. great book. i'll pass that around. did you want to mention anything about it. >> i was going to touch upon the block book one last time. the library if you look on page 9 of the research guide they've got the block books from 1960, 94, 06, 07', 09' and 10. there was long thought to be along ellipse from the early part of the 20th century but i recently like two years ago found out the assessors office has the 19, 14 all the way through 1974 block books if you find your block and lot you can find out who owned that

building up to the 50s i believe. at least through 1946 because we have a copy of the 46 so you can find out who lived there and if you go to the asses ri quarters office and they don't know what your talking about if you're looking straight ahead, there's a balcony that goes around the upper level and on the far left side there's a column that comes down from the call connie and it's at the base of that column that you can direct the researcher to go to get these micro films. >> talk about secrets of city government. that's great. >> i guess that's what i had to say. there's a little secret document out there. >> in terms of working with these agencies and little places where all this information lies, just as i was

talking about how excited people are at the public library history room to help you you will find there's agencies not there to help you research your home as you might find. the assessor is thinking their job is to asses your home for taxation so your interest is not their concern necessarily. we talked about the property card each property has. this building card. most clerks when you approach them and ask for that they will send you to a computer monitor so to see what they have on-line. stand firm. you want to see the source document. they'll do it if you push them to do it. >> okay. couple more resources here. >> when you find out the people that used to live in

your building, you can then go to the san francisco directories and their available that public libraries and they have many many years worth of these and you can find out that lawrence fox was married to betty who was a stockbroker and presided at 42 pacific avenue. you can find out if the owner was also occupying the building they owned so you can start to build a biography of the people that lived in your house through these city directors. >> i wanted to mention the building department has miscallaneous records of all sorts and let me just, a lon the length of letting you into the inner city secrets of records being kept. this is the unreenforced masonry building survey.

we have people here on the third -- second floor that do upgrade work and we surveyed all the buildings and there's photographs and descriptions and some of it made it to the building department of records and we have soils reports. maybe very valuable if there's a voils report of your neighborhood. i bought my house and thought it was in ma great location. but the earthquake turns out shook our neighborhood really badly. the soils reports would have shown me that and will show you that and we have maybe tens of thousands by block and lot number here on the second floor that building department. on the six floor is the housing inspection division.

they have their own separate records, what they call street files for buildings three or more units and sometimes fewer occasionally if their stuck away in there they have inspection records of all the multi-family buildings in san francisco and they're suppose to go out and look at them once every five years unfortunately, they recently cleaned the files out and we lost a lot of the day-to-day records of people. we have the summary documents but there's still quite a few. here's the secret. you look that files up there and you open it up and there's all these records and a lot of stuff you don't know sm gone, but inside the file is a pocket and inside the pock seat microfiche so, then you can request copies. how do they do that.

>> there's a viewer to see, you can stick them in and see what documents are on that and if you need copies someone from housing will escort you to the micro film counter and wait your turn to get whatever prints you need. >> those are very valuable records and your goal should be to put together that complete binder. let's see. what other information. oh, the 76 survey files upstairs. >> we have the original files and we also, i guess there are two secret things i can share. lawrence held up the binder for the unreenforced masonry building. if your buildings on there and you think it's quite snappy, we have the negatives. we also have the negatives from

the 1976 survey and if you make an appointment with me and my number is up there, i can make arrangements to have enlargements of these made for you. then, the 76 survey itself was a windshield survey that the planning department worked on with some graduate students that looked at what they felt in their served jury pool to be the representative top ten percent of the top stylist architecture so they gave us photograph and some information of the outside of the building from 1976 often thousand buildings in every part of the

city. >> how do you know if yours is on that list. >> the planning department has a list of all the surveys any given property may not have background information on. you can call the planning information counter and ask that it be looked up and you can come in and -- >> -- okay. planning information counter. 583877. best to call early in the morning and be patient. we're currently under staffed. i would call at 8 o'clock. 8 a.m. and 30 minutes after. if you call at thirty to 5 preponderance you might not get anyone. >> we're almost done. another couple of minutes.

but i want to point out one of the easiest references lying around the counter. we have one on the first floor of this building and one on the six floor and the floor next door. the san francisco realty directory. if you look at this you can find by address, on or broad rick street, the construction or type, single family dwelling, zoning code, value, block and lot. last sales date. walk up and all this information is right there so you don't even need to go to the library for that. >> that's information from the

tax assessor so it should be the same information as the tax assessor. >> it's a good simple starting point. jeremy, what's that magnifying glass for that you have in your pocket. >> just because it has that sherlock holmes thing. so much of what i do involves looking through directories and all of these map's for changes that have been made and tracking when those things were done and there are other sources in text that can be very difficult to get through but have really wonderful pieces of information. the voters rolls. the pulp directories tell you things about the fabric of the city. i had an interesting case to establish a legal dwelling unit

that had to pre date a certain date with a ceiling height and it turns out a person resided at this address that was a bartender and a regular sterd socialist. the owner of the building that lived there owned the bar and he was the current chairman of the socialist party of the city. with that city planning was willing to acknowledge the bartender lived in his bosses unit in the basement of his house. there you have it. >> amazing. we will stick around and answer questions after but we have to stop right now because the time is up and i want to thank jeremy, paul, and moses and alan and thank you all for coming and we'll see you next

month. thanks.

>> welcome to the brown bag

lunch, i am lawrence cornfield. we are here at beverly prior's law office. we are going to look at one of the greenest business office spaces in san francisco. you just celebrated the first anniversary of your green office space >> there are many elements. what we're celebrating, what you say it's one of the greenest office buildings. it's the contribution methodology. the materials mechanical systems that we look at. we are using recycles materials. how off gases. >> all focussed toward the goal

of reducing impacts? >> exactly. we are using materials that are rapidly renewable. there's another aspect. there are many aspects to being green >> what lead you to this green office? >> it's an interesting story. these kinds of thing start with gee, it's time to find a new office of our idea has evolved over time. how do we work together? what kind of space do we want that will support what we want?

we have very ambitious goals. all those things started to factor in. we had a brain storm session and made it clear, it's not an ideal world, we are not going to be able to get all the things they like. we ask people to prioritize and across the board, the staff said they want a sustainable office. it's a leed silver and we got excited it went to leed gold >> wow. so leed has a series of standards. starting with leed certified.

you have met a high level the sustainability. you can go to leed silver or gold. it's leadership of environmental design. it's a process of the u.s. green building council. beverly is ahead of this curve. we see every new building as sustainable features. they are not all leed certified. that's what the market demands >> our work is in the public sector. community colleges and so on. 5 years ago, we were trying to get them to think about it. then think about california is on the forefront of nation. san francisco is on the

forefront of state >> and beverly prior is way up there. we are up there at the top. it sounds like the challenge came to making this physical reality achiefable. what is the marginal cost? every always asks me. what is the marginal costs. may be i shouldn't ask. i have to say, there's a huge difference. between building a building from scratch, where you can design at will features from the ground up and the marginal cost then when you take an existing building. you were talking about major

changes. i presume that has a major impact. >> we don't own the building. so the landlord gave us an allowance. we had to make a bigger commitment. there's actually, sala might want to share about that. we had to convince the landlord in many cases. not everything that's green is about our tenant space. there's the restrooms, which the landlord had control over. making decisions about the mechanical. it was part of our strategy, whenever we started to raise the green flag, the landlord would say wo. >> it was part of that, i love

that that leed stands for is leadership it energy and environmental design. part of leadership is bringing people along and having them see the benefits. at least for their own pocket book. that was part of our strategy to have the landlord buy into the some of the strategies, but how it's making sense for them as business owners >> the long time returns, how many years you look at the 10-year cycle and evaluate these things >> i just realize i didn't answer your question about the marginal costs. one of the things is you hear about how much more does it cost to do leed and so on. there are those out there that

tell you it's minimal, one or 2 percent. i think they are talking against a brand-new project where you have a lot of influence on things. >> by the way, we have done enough documentation on new buildings to show that meeting certain leed standards, i think we're looking at leed gold was a 2 to 5 percent marginal increase for a brand-new building. >> to even get leed silver. there's no additional cost because in california, the state energy codes and all these different things are supportive of good quality, so the state is really coming along too. in terms of percent, marginal. do you want to say sala? it
